Patent Application
20220241914
The subject matter herein generally relates to a fixing jig for positioning a workpiece.
In a vibration test of a workpiece of a computer server, a stopper is usually used to fix a displacement of the workpiece in a horizontal direction. However, gaps may exist between the stopper and the workpiece, which will reduce the accuracy of vibration testing.
Implementations of the present disclosure will now be described, by way of embodiments, with reference to the attached figures.
It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. Additionally, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures and components have not been described in detail so as not to obscure the related relevant feature being described. The drawings are not necessarily to scale and the proportions of certain parts may be exaggerated to better illustrate details and features. The description is not to be considered as limiting the scope of the embodiments described herein.
Several definitions that apply throughout this disclosure will now be presented.
The term “coupled” is defined as connected, whether directly or indirectly through intervening components, and is not necessarily limited to physical connections. The connection can be such that the objects are permanently connected or releasably connected. The term “substantially” is defined to be essentially conforming to the particular dimension, shape, or another word that “substantially” modifies, such that the component need not be exact. For example, “substantially cylindrical” means that the object resembles a cylinder, but can have one or more deviations from a true cylinder.
The term “comprising” means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in a so-described combination, group, series, and the like.
The receiving groove 10a penetrates a bottom surface of the fixing member 10, and a bottom surface of the stopper 20 is flush with the bottom surface of the fixing member 10 and contacts the top surface of the support plate 100a, so that the stopper 20 is always located on the support plate 100a. Thus, the stopper 20 is prevented from shaking or excessively deforming.
In order to reduce a contact area with the workpiece 200, the stopper 20 includes a main body 21 and a pushing portion 22. The main body 21 is slidably received in the receiving groove 10a. The pushing portion 22 is coupled to one end of the main body 21 protruding from the receiving groove 10a. A length of the main body 21 is greater than a length of the pushing portion 22. A width of the main body 21 is the same as a width of the pushing portion 22. A cross-sectional area of the pushing portion 22 is smaller than a cross-sectional area of the main body 21. In one embodiment, both the main body 21 and the pushing portion 22 are substantially a rectangular parallelepiped, and a height of the pushing portion 22 is less than a height of the main body 21.
In order to reduce internal stress and deformation of the stopper 20, the bottom surface of the pushing portion 22 is flush with the bottom surface of the main body 21, so that the stopper 20 as a whole adheres to the support plate 100a, and a top surface of the pushing portion 22 is coupled to a top surface of the main body 21 through an inclined surface 23 to prevent excessive stress at a connection between the pushing portion 22 and the main body 21, which improves a bonding strength between the pushing portion 22 and the main body 21 and prevents the pushing portion 22 from breaking off the main body 21.
In order to further reduce the internal stress and deformation of the stopper 20, a rounded edge 24 is arranged between the inclined surface 23 and the top surface of the pushing portion 22. The rounded edge 24 is used to improve the bonding strength between the pushing portion 22 and the main body 21 to prevent the pushing portion 22 from breaking off the main body 21 when the workpiece 200 is pushed.
The cross-sectional shape of the main body 21 is the same as the cross-sectional shape of the receiving groove 10a. Thus, a side of the receiving groove 10a slidably contacts an outer side of the stopper 20, thereby preventing the stopper 20 from rotating in the sliding groove 10a.
In one embodiment, the adjusting member 30 can adjust a distance that the stopper 20 extends from the receiving slot 10a within a range of 4-5.5 cm.
As shown in
In summary, the workpiece 200 is placed on the support plate 100a. The adjusting member 30 is rotated so that the stopper 20 abuts the workpiece 200 until the workpiece 200 is fixed in the horizontal direction. When the workpiece 200 is adjusted, the locking member 40 is rotated to lock the position of the stopper 20, thereby locking the position of the workpiece 200 in the horizontal direction. Then, the height of the beams 100c is adjusted to press the workpiece 200 onto the support plate 100a, thereby stabilizing the position of the workpiece 200 in the vertical direction.
As shown in
A vibration testing machine (not shown in the figures) may include a vibrator and the fixing jig 100. The fixing jig 100 is used to position the workpiece, and the vibrator is used to vibrate the fixing jig 100 to drive the workpiece to vibrate.
The embodiments shown and described above are only examples. Even though numerous characteristics and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the detail, including in matters of shape, size and arrangement of the parts within the principles of the present disclosure up to, and including, the full extent established by the broad general meaning of the terms used in the claims.
