BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to an auxiliary component for the operation of a material cutting machine, and more particularly to an innovative structural design of an auxiliary adjusting and abutting device for a material cutting machine.

2. Description of Related Art Including Information Disclosed Under 37 CFR 1.97 and 37 CFR 1.98

During operation of a material cutting machine (e.g., a rotary blade bench saw, a wood milling machine etc.), when the user wants to cut out a workpiece of a narrow width from the material (e.g., 3 mm), usually an abutting and positioning piece will be configured on the bench for the material to abut. In this way, an accurate cutting size can be obtained. The prior-art auxiliary adjusting and abutting device for a material cutting machine comprises a fixing seat positioned on the material cutting machine and a movable adjusting seat. The two sides of the adjusting seat is assembled with a transparent plate with a zero position marks. The two sides of the fixing seat is correspondingly configured with scale marks for feeding of the material. During operation, the abutting end of the adjusting seat is abutted on the side of the saw blade, and the transparent plate is moved to align its zero position line to one scale mark line for material feeding on the fixing seat. Then, the transparent plate is locked to complete the resetting operation. Then, adjust the adjusting seat to a preset workpiece cutting dimension, and lock up the adjusting seat. In this way, when the cutting side of the material to be cut is abutted to the abutting end of the adjusting seat, an accurately cut workpiece can be obtained.

However, in actual applications, it is found that the above-mentioned prior-art structure still has some problems and shortcomings. For example, because the cutting environment is full of fine powders, when the transparent plate of the prior-art structure with the zero position mark covers the scale marks configured on the fixing seat to display the cutting size, the transparent plate may have deposit of dust or scratches, causing blur and difficult recognition. Furthermore, the zero position mark of the transparent plate is usually aligned to the middle section of the scale marks configured on the fixing seat for resetting. However, when the cutting size is adjusted, the user must clearly remember the correct marking line aligned to during the resetting, otherwise the value of the adjusted distance will be mistaken. Therefore, the prior-art structure does not provide good size recognition.

In addition, in the material processing field, the dimension marks are mostly based on the decimal form of metric or English measurement systems (e.g., in the case of metric unit mm, a longer marking line with an integer number mark is provided for every length of 10 mm to facilitate recognition). Therefore, during application of the prior-art structure, if the workpiece to be obtained has a cutting width exceeding one integer mark (e.g., 13 mm), the operator may easily forget or be confused about which range is the current adjusted position is located within, and will have to redo the resetting. Because the user cannot do the operation intuitively, it is quite inconvenient.

DETAILED DESCRIPTION OF THE INVENTION

Depicted in the FIG. 1 to FIG. 6 is a preferred embodiment of the auxiliary adjusting and abutting device for a material cutting machine according to the present invention. However, such a preferred embodiment is for illustrative purpose only and is not intending to limit the scope of the invention.

The material cutting machine 05 (e.g., a rotary blade bench saw, wood milling machine) is used for the cutting operation of a material 06. The auxiliary adjusting and abutting device 100 comprises a base 10, comprising a front section part 11 and a rear section part 12, wherein the top face of the front section part 11 is formed with a guiding groove 13, and the bottom face of the rear section part 12 has a mounting component 14. The top face of the rear section part 12 is formed with a limiting part 15 (can be, but not limited to, a through-hole type), and the base 10 is defined with a material feeding direction L1 and a cutting width adjusting direction L2 based on the status of the cutting operation of the material 06. The cutting width adjusting direction L2 and the material feeding direction L1 are perpendicular to each other, and the guiding groove 13 is configured along the cutting width adjusting direction L2. A sliding seat 20 is configured inside the guiding groove 13 of the base 10 in a manner that it can slide along the cutting width adjusting direction L2. The sliding seat 20 comprises a passive end 21 and an abutting end 22. The abutting end 22 is used to abut against one side of the material 06, and the abutting end 22 protrudes out of the front section part 11 of the base 10. The passive end 21 is configured with a passive connected part 23. An adjusting assembly 30 is configured between the passive end 21 of the sliding seat 20 and the limiting part 15 of the base 10. The adjusting assembly 30 at least comprises a connecting tube part 31 and a rotary tube 32 in the shape of a hollow through tube. The connecting tube part 31 is assembled on the limiting part 15 of the rear section part 12 of the base 10. The rotary tube 32 comprises a first end 321 and second end 322, wherein the first end 321 and the connecting tube part 31 are in threaded connection through a male and female thread joint section 33. The second end 322 of the rotary tube 32 is assembled on the passive connected part 23 of the sliding seat 20 in a relatively rotatable manner, so that, when the rotary tube 32 rotates clockwise or anticlockwise, the sliding seat 20 will be driven to move forward or backward. A ruler rod 40 is configured inside the connecting tube part 31 and the rotary tube 32 in the shape of a hollow through tube of the adjusting assembly 30 in a coupling relationship that allows movement in a fixed direction. The ruler rod 40 comprises a control rod head 41 and a tail rod section 42, wherein the control rod head 41 protrudes out of the connecting tube part 31, the tail rod section 42 is sleeved on the rotary tube 32 and placed on the passive connected part 23 of the sliding seat 20, and a zero position 43 and size scales 44 are configured from the control rod head 41 to the tail rod section 42. A connecting and positioning piece 50 is screwed on the passive connected part 23 of the sliding seat 20. The connecting and positioning piece 50 comprises an operating part 51, a screw joint part 52, and a locking end 53 (see FIG. 8). The passive connected part 23 is configured with a screw hole 235 for threaded connection with the screw joint part 52. The connecting and positioning piece 50 has a released mode and a locked mode. When in the locked mode, as shown in FIGS. 5 to 6, the locking end 53 is locked on the ruler rod 40, so that the ruler rod 40 and the sliding seat 20 can move simultaneously; whereas in the released mode, as shown in FIG. 7, the ruler rod 40 can move relatively forward or backward inside the adjusting assembly 30.

As shown in FIG. 2, in the present embodiment, the control rod head 41 of the ruler rod 40 is further formed with a ring flange 45, so that the location of the ring flange 45 is equivalent to the zero position. The advantage of the design disclosed in the present invention is that the resetting can be realized when the ring flange 45 abuts the end portion of the connecting tube part 31. It can be understood that, when without the configuration of a ring flange 45, the zero position can also be pure scale marks or other marks.

Referring to FIG. 2, in the present embodiment, one side of the ruler rod 40 is formed with an axial bolt slot 46. The terminal ends of the axial bolt slot 46 do not go through the control rod head 41 and the tail rod section 42 and is formed with two spaced convex walls 47. The locking end 53 of the connecting and positioning piece 50 firstly sticks into the axial bolt slot 46 and is then locked on the ruler rod 40, so that the ruler rod 40 and the adjusting assembly 30 are in a coupling relationship that they can only move in a fixed direction. Disclosed in this example is a preferred embodiment in which the ruler rod 40 and the adjusting assembly 30 are in a coupling relationship that they can only move in a fixed direction and their positions are limited to avoid falling off.

In addition, the ruler rod 40 and the adjusting assembly 30 are in a polygonal coupling relationship, so that the locking end 53 of the connecting and the positioning piece 50 is locked on one side of the polygon of the ruler rod 40, so that the ruler rod and the adjusting assembly are in a coupling relationship that they can only move in a fixed direction. (Note: the present embodiment is omitted in the figure. The advantage of the assembly design of the present embodiment is that, based on the matching sections of the locking end 53 and the ruler rod 40, the locking between them can be more effective.)

Referring to FIG. 2, in the present embodiment, the passive connected part 23 of the sliding seat 20 is in the shape of a hollow tube, and the passive connected part 23 and the second end 322 of the rotary tube 32 are in threaded connection through a second male and female thread joint section 70, so that, when the rotary tube 32 rotates, it will move axially forward or backward in relation to the passive connected part 23. In the design disclosed in the present embodiment, the rotary tube 32 can rotate, and both ends are threaded form guided movement, thus enhancing the rotary movement. Furthermore, the passive connected part 23 is formed with a shoulder part 237 and is aligned to the passive end 21 of the sliding seat 20. The passive end 21 is locked with a plurality of positioning bolts 215. Each positioning bolt 215 has a bolt head 217 to abut against the shoulder part 237 (see FIG. 4), so as to fix the passive connected part 23.

Referring to FIG. 2, in the present embodiment, the top face of the front section part 11 of the base 10 is further configured with two limiting frames in the form of a pair 80 on both sides of the guiding groove 13. Each limiting frames 80 has a pressing claw part 81. The sliding seat 20 is correspondingly formed with two guiding troughs in the form of a pair 24, respectively for the pressing claw part 81 of each of the limiting frames 80 to insert and be coupled. As a preferred embodiment, the present embodiment is designed to limit the movement stroke of the sliding seat 20 and the assembly state.

Referring to FIG. 2 to FIG. 4, in the present embodiment, the abutting end 22 of the sliding seat 20 is further configured with a rotary rolling piece 90 (can be, but not limited to, a metal wheel).

Based on the above structural designs and technical features, the actual operation of the auxiliary adjusting and abutting device 100 disclosed in the present invention is as illustrated in FIG. 9. Through the mounting component 14 on the bottom face of the rear section part 12 of the base 10, the device can be mounted at the position of a preset mounting trough 08 with a distance to the cutting part 07 (e.g., the rotary blade or the milling cutter) of an existing material cutting machine 05 (e.g., a rotary blade bench saw, a wood milling machine etc.), so that the whole auxiliary adjusting and abutting device 100 can move along the material feeding direction L1 to adjust the cutting width. During operation of the present invention, firstly the rotary tube 32 of the adjusting assembly 30 needs to be rotated to drive the abutting end 22 of the sliding seat 20 to move along the cutting width adjusting direction L2 (as indicated by Arrow L3 in FIG. 9), till the abutting end 22 abuts the cutting part 07. Then, conduct the resetting of the ruler rod 40. As shown in FIG. 6, the user applies a force to push the ruler rod 40 (in the direction indicated by Arrow L4) so that its ring flange 45 abuts the end portion of the connecting tube part 31, thus completing the resetting action. Then, as shown in FIG. 7, the connecting and positioning piece 50 is set to the locked mode (in the direction indicated by Arrow L5), so that the passive connected part 23, the ruler rod 40 and the sliding seat 20 move simultaneously. Then, as shown in FIG. 10, the whole auxiliary adjusting and abutting device 100 is pushed along the material feeding direction L1 (in the direction indicated by Arrow L6), and adjusted to the front side of the cutting part 07 in a crossing form. Now, the user adjusts the cutting width by turning the rotary tube 32 (as indicated by Arrow L7 in FIG. 7) of the adjusting assembly 30 to drive the abutting end 22 of the sliding seat 20 to move away from the cutting part 07 (as indicated by Arrow L8 in FIG. 7 and FIG. 10). The size scales 44 of the ruler rod 40 will be moved beyond the end portion of the connecting tube part 31, as shown in FIG. 10. If, for example, the value of the size scales 44 reads 5 mm, it means the cutting width value of the abutting end 22 of the sliding seat 20 is 5 mm. In the end, as shown in FIG. 11, the abutting end 22 is used to abut against one side of the material 06, then the material 06 is moved along the material feeding direction L1. In this way, after cutting of the material 06 by the cutting part 07, a cut finished product 09 with the width value of 5 mm can be obtained. The cutting width is very accurate.

It is to be noted that, because the assembly between the ruler rod 40 and the adjusting assembly 30 can be easily dismantled, manufacturers can easily use different ruler rods to change the metric/English dimension system mode of the scale marks, adding more flexibility to the product structure.
