This application claims the benefit of priority to Taiwan Patent Application No. 112116526, filed on May 4, 2023. The entire content of the above identified application is incorporated herein by reference.
Some references, which may include patents, patent applications and various publications, may be cited and discussed in the description of this disclosure. The citation and/or discussion of such references is provided merely to clarify the description of the present disclosure and is not an admission that any such reference is “prior art” to the disclosure described herein. All references cited and discussed in this specification are incorporated herein by reference in their entireties and to the same extent as if each reference was individually incorporated by reference.
The present disclosure relates to a fixture, and more particularly to a grinding apparatus and a crystal orientation adjustment fixture thereof.
A crystal orientation adjustment mechanism in a conventional grinding device provided for adjusting a crystal orientation of a to-be-processed object is operated in a rough manner (e.g., beating two ends of the to-be-processed object by a rubber hammer), so that an amplitude of the crystal orientation of the to-be-processed object is large. This makes the crystal orientation adjustment mechanism difficult to meet crystal orientation requirements that are gradually becoming stricter.
In response to the above-referenced technical inadequacies, the present disclosure provides a grinding apparatus and a crystal orientation adjustment fixture thereof for effectively improving on the issues associated with conventional grinding devices.
In order to solve the above-mentioned problems, one of the technical aspects adopted by the present disclosure is to provide a grinding apparatus, which includes a grinding machine and two crystal orientation adjustment fixtures. The grinding machine includes two rotational shafts arranged along an arrangement axis. The two crystal orientation adjustment fixtures are respectively assembled to the rotational shafts and are configured to respectively clamp two ends of a to-be-processed object. Each of the two crystal orientation adjustment fixtures includes a fixing seat, an adjustment body, a first adjustment component, and a universal mandrel module. The fixing seat is assembled to the corresponding rotational shaft. The adjustment body has a rear end surface and a front end surface that is opposite to the rear end surface. The adjustment body is assembled to the fixing seat through the rear end surface. The adjustment body has a universal slot recessed in the front end surface, and the adjustment body has a first adjustment slot that is recessed along an adjustment direction and that has a bottom corresponding in position to the fixing seat. The first adjustment component is movably assembled to the first adjustment slot along the adjustment direction and abuts against the fixing seat. The universal mandrel module is rotatably assembled to the universal slot and is configured to abut against the to-be-processed object. The first adjustment components of the two crystal orientation adjustment fixtures and the arrangement axis are arranged on an adjustment plane, and the two first adjustment components are diagonally opposite to each other. The two first adjustment components are adjustable along the adjustment direction by a same distance, such that the two adjustment bodies are moved relative to the two fixing seats along the adjustment direction and are respectively moved in two opposite directions away from each other, thereby rotating the to-be-processed object in the adjustment plane.
In order to solve the above-mentioned problems, another one of the technical aspects adopted by the present disclosure is to provide a crystal orientation adjustment fixture of a grinding apparatus, which includes a fixing seat, an adjustment body, a first adjustment component, and a universal mandrel module. The adjustment body has a rear end surface and a front end surface that is opposite to the rear end surface. The adjustment body is assembled to the fixing seat through the rear end surface. The adjustment body has a universal slot recessed in the front end surface, and the adjustment body has a first adjustment slot that is recessed along an adjustment direction and that has a bottom corresponding in position to the fixing seat. The first adjustment component is movably assembled to the first adjustment slot along the adjustment direction and abuts against the fixing seat. The universal mandrel module is rotatably assembled to the universal slot and is configured to abut against one end of a to-be-processed object.
Therefore, the crystal orientation adjustment fixture provided by the present disclosure can be applied to the grinding machine of different types, and the crystal orientation adjustment fixture can be configured to effectively reduce an amplitude of movement or adjustment of the to-be-processed object, such that a fine-adjustment of crystal orientation of the to-be-processed object can be implemented for meeting different requirements.
Moreover, in the grinding apparatus provided by the present disclosure, the two crystal orientation adjustment fixtures have a specific relationship therebetween (e.g., the first adjustment components of the two crystal orientation adjustment fixtures and the arrangement axis are arranged on an adjustment plane, and the two first adjustment components are diagonally opposite to each other) for precisely implementing the fine-adjustment of crystal orientation of the to-be-processed object.

Referring to
The grinding apparatus 1000 includes a grinding machine 200 and two crystal orientation adjustment fixtures 100 that are assembled to the grinding machine 200, and the two crystal orientation adjustment fixtures 100 of the grinding apparatus 1000 in the present embodiment are arranged in a 2-fold rotational symmetry, but the present disclosure is not limited thereto. For example, in other embodiments of the present disclosure not shown in the drawings, the crystal orientation adjustment fixture 100 can be independently used (e.g., sold) or can be used in cooperation with other components.
In the present embodiment, the grinding machine 200 is configured to grind the to-be-processed object I. The grinding machine 200 includes two rotational shafts 201 arranged along an arrangement axis L. The two crystal orientation adjustment fixtures 100 are respectively assembled to the two rotational shafts 201, and are configured to respectively clamp two ends of the to-be-processed object I. In other words, a central axis of the to-be-processed object I can be arranged on (or overlapped with) the arrangement axis L.
It should be noted that as the two crystal orientation adjustment fixtures 100 in the present embodiment are of substantially the same structure, the following description discloses the structure of just one of the two crystal orientation adjustment fixtures 100 for the sake of brevity, but the present disclosure is not limited thereto. For example, in other embodiments of the present disclosure not shown in the drawings, the two crystal orientation adjustment fixtures 100 can be of different structures.
As shown in
The fixing seat 1 is assembled (e.g., threaded) to the corresponding rotational shaft 201 of the grinding machine 200, so that the crystal orientation adjustment fixture 100 and the corresponding rotational shaft 201 can be synchronously rotated. In other words, the relative position of the fixing seat 1 and the corresponding rotational shaft 201 can be maintained and fixed.
Moreover, the adjustment body 2 includes a rear end surface 21, a front end surface 22 being opposite to the rear end surface 21, and a surrounding lateral surface 23 that is arranged between the rear end surface 21 and the front end surface 22. The adjustment body 2 is assembled to the fixing seat 1 through the rear end surface 21, and the adjustment body 2 is movable relative to the fixing seat 1 along an adjustment direction D (that is perpendicular to the arrangement axis L). The movement distance of the adjustment body 2 along the adjustment direction D can be less than or equal to 0.5 mm, but the present disclosure is not limited thereto. For example, in other embodiments of the present disclosure not shown in the drawings, the movement distance can be increased according to design requirements (e.g., the to-be-processed object I needs to be adjusted by a large angle).
Specifically, the adjustment body 2 has a universal slot 24 and a plurality of buffering slots 25. The universal slot 24 and the buffering slots 25 are recessed in the front end surface 22. In the present embodiment, the universal slot 24 penetrates through the adjustment body 2 from a center of the front end surface 22 to the rear end surface 21 along the arrangement axis L, and the buffering slots 25 surround the universal slot 24 and are spaced apart from each other by a same distance.
Moreover, the adjustment body 2 in the present embodiment includes two slanting surfaces 211 arranged on the rear surface 21, two airflow channels 212 recessed in the rear surface 21, and two protruding portions 213 that protrude from the rear surface 21 and that are approximately located between the two slanting surfaces 211, but the present disclosure is not limited thereto. For example, in other embodiments of the present disclosure not shown in the drawings, a quantity of the two slanting surfaces 211 can be at least one, a quantity of the two airflow channels 212 can be at least one, and the two protruding portions 213 can be omitted according to design requirements.
The two slanting surfaces 211 are located at two opposite sides of the universal slot 24 and are mirror-symmetrical relative to the arrangement axis L, and an angle σ between the arrangement axis L and each of the two slanting surfaces 211 is within a range from 30 degrees to 60 degrees (e.g., the angle σ is preferably within a range from 25 degrees to 45 degrees), but the present disclosure is not limited thereto. In addition, the adjustment body 2 can tightly abut against the fixing seat 1 through any one of the two slanting surfaces 211, and the fixing seat 1 and a part of the rear end surface 21 other than the two slanting surfaces 211 have a gap G therebetween (e.g., the gap G can be substantially 1 mm, but the present disclosure is not limited thereto), thereby facilitating the adjustment between the adjustment body 2 and the fixing seat 1. Moreover, the gap G can be used for monitoring a service life of the crystal orientation adjustment fixture 100 (e.g., the service life of the crystal orientation adjustment fixture 100 is deemed to be expired when the gap G disappears), such that the crystal orientation adjustment fixture 100 can be controlled more intuitively.
Specifically, each of the two slanting surfaces 211 has a substantial rectangular shape having a longitudinal direction parallel to the adjustment direction D, two short edges of each of the two slanting surfaces 211 are connected to the surrounding lateral surface 23 of the adjustment body 2, and a distance between the two slanting surfaces 211 gradually increases in a direction along the arrangement axis L and toward the front end surface 22.
Moreover, the two airflow channels 212 are respectively located at two outer sides of the two slanting surfaces 211, each of the two airflow channels 212 has an elongated shape parallel to the adjustment direction D, and an edge (or an inner side wall) of each of the two airflow channels 212 is connected to a long edge of an adjacent one of the two slanting surfaces 211. In addition, two ends of each of the two airflow channels 212 are in spatial communication with the surrounding lateral surface 23, and the two airflow channels 212 are in spatial communication with bottoms of the buffering slots 25.
The adjustment body 2 has a first adjustment slot 26 that is recessed along the adjustment direction D and a second adjustment slot 27 that is recessed along an extending path of the first adjustment slot 26. Moreover, a bottom of the first adjustment slot 26 and a bottom of the second adjustment slot 27 correspond in position to (or are arranged adjacent to) the fixing seat 1, and each of the first adjustment slot 26 and the second adjustment slot 27 is an inner threaded slot, but the present disclosure is not limited thereto.
Specifically, each of the first adjustment slot 26 and the second adjustment slot 27 penetrates through the adjustment body 2 along the adjustment direction D from the surrounding lateral surface 23, and the first adjustment slot 26 and the second adjustment slot 27 are respectively formed in the two protruding portions 213. It should be noted that any one of the first adjustment slot 26 and the second adjustment slot 27 is at least partially arranged between the two slanting surfaces 211.
The first adjustment component 3 is movably assembled to the first adjustment slot 26 along the adjustment direction D and abuts against the fixing seat 1, and the second adjustment component 4 is movably assembled to the second adjustment slot 27 along the adjustment direction D and abuts against the fixing seat 1. Each of the first adjustment component 3 and the second adjustment component 4 is a stop screw, and the first adjustment component 3 and the second adjustment component 4 are respectively threaded into the first adjustment slot 26 and the second adjustment slot 27, but the present disclosure is not limited thereto.
Specifically, ends of the first adjustment component 3 and the second adjustment component 4 adjacent to each other respectively pass through the first adjustment slot 26 and the second adjustment slot 27 for jointly clamping the fixing seat 1. Moreover, the first adjustment component 3 (or the second adjustment component 4) can be adjusted along the adjustment direction D so as to move the adjustment body 2 relative to the fixing seat 1 along the adjustment direction D, thereby moving the to-be-processed object I.
Accordingly, the crystal orientation adjustment fixture 100 in the present embodiment can be applied to the grinding machine 200 of different types, and the crystal orientation adjustment fixture 100 can be configured to effectively reduce an amplitude of movement or adjustment of the to-be-processed object I (e.g., the movement of any one end of the to-be-processed object I can be controlled to be less than 0.5 mm, but the present disclosure is not limited thereto), such that a fine-adjustment of crystal orientation of the to-be-processed object I can be implemented for meeting different requirements.
The universal mandrel module 5 is rotatably assembled to the universal slot 24 of the adjustment body 2 for abutting against the to-be-processed object I. It should be noted that the universal mandrel module 5 can be formed of different structures according to design requirements, and the following description describes the universal mandrel module 5 formed of a preferred one of the structures for the sake of brevity, but the present disclosure is not limited thereto.
The universal mandrel module 5 in the present embodiment includes a universal bearing kit 51, a mandrel head 52 assembled to the universal bearing kit 51, and a plurality of buffering components 53 that abut against the mandrel head 52. The universal bearing kit 51 is assembled in the universal slot 24 and is not in contact with the fixing seat 1, and the universal bearing kit 51 is formed by a plurality of components that are not described herein for the sake of brevity.
The mandrel head 52 includes a plate 521 and a column 522 that is (perpendicularly) connected to the plate 521. The plate 521 has a contacting surface 5211 that is roughened and that is arranged on one side thereof for abutting against the to-be-processed object I. The column 522 extends from a substantial center portion of another side of the plate 521. The mandrel head 52 is assembled to the universal bearing kit 51 through the column 522, and the mandrel head 52 is rotatable relative to the adjustment body 2 through the universal bearing kit 51.
The buffering components 53 are respectively assembled to the buffering slots 25, and an end of each of the buffering components 53 protrudes from the corresponding buffering slot 25 and abuts against the plate 521. In the present embodiment, the buffering components 53 are of substantially the same structure, and each of the buffering components 53 includes a spring 531 arranged in the corresponding buffering slot 25 and a locating pin 532 that is in contact with the spring 531 and that partially protrudes from the corresponding buffering slot 25. The shape of the locating pin 532 in the present embodiment is similar to that of a bullet nose, but the present disclosure is not limited thereto. The locating pin 532 of each of the buffering components 53 abuts against the another side of the plate 521 through the spring 531, thereby firmly maintaining the position of the plate 521.
The above description describes the structure of one of the two crystal orientation adjustment fixtures 100, and the two crystal orientation adjustment fixtures 100 of the grinding apparatus 1000 have a specific relationship therebetween for precisely implementing the fine-adjustment of crystal orientation of the to-be-processed object I. As shown in
In summary, the two first adjustment components 3 are adjustable along the adjustment direction D by a same distance, such that the two adjustment bodies 2 are moved relative to the two fixing seats 1 along the adjustment direction D and are respectively moved in two opposite directions away from each other, thereby rotating the to-be-processed object I in the adjustment plane P. In addition, the two second adjustment components 4 can be adjusted according to the positions of the two first adjustment components 3, such that the first adjustment component 3 and the second adjustment component 4 of each of the two crystal orientation adjustment fixtures 100 can be maintained to abut against (or clamp) the fixing seat 1.
In conclusion, the crystal orientation adjustment fixture provided by the present disclosure can be applied to the grinding machine of different types, and the crystal orientation adjustment fixture can be configured to effectively reduce an amplitude of movement or adjustment of the to-be-processed object, such that a fine-adjustment of crystal orientation of the to-be-processed object can be implemented for meeting different requirements. In addition, the grinding apparatus of the present embodiment can be used to directly implement the crystal orientation adjustment to the to-be-processed object by using the grinding machine without needing to repeatedly disassemble components thereof.
Moreover, in the grinding apparatus provided by the present disclosure, the two crystal orientation adjustment fixtures have a specific relationship therebetween (e.g., the first adjustment components of the two crystal orientation adjustment fixtures and the arrangement axis are arranged on an adjustment plane, and the two first adjustment components are diagonally opposite to each other) for precisely implementing the fine-adjustment of crystal orientation of the to-be-processed object. Specifically, the grinding apparatus in the present embodiment is provided with functions for rotating angle and adjusting crystal orientation, and a reference point of the above functions is set at a center position of the to-be-processed object, thereby ensuring that a maximum adjustable angle of crystal orientation can be adjusted according to a required angle. Moreover, the angle can be adjusted to a precision of 0.1 degrees, but the present disclosure is not limited thereto.
The foregoing description of the exemplary embodiments of the disclosure has been presented only for the purposes of illustration and description and is not intended to be exhaustive or to limit the disclosure to the precise forms disclosed. Many modifications and variations are possible in light of the above teaching.
The embodiments were chosen and described in order to explain the principles of the disclosure and their practical application so as to enable others skilled in the art to utilize the disclosure and various embodiments and with various modifications as are suited to the particular use contemplated. Alternative embodiments will become apparent to those skilled in the art to which the present disclosure pertains without departing from its spirit and scope.
