[0026] See also Figure 1-3 A machine tool fixture comprises a support plate 1, a fixed block 2, an adjusting block 3, a threaded rod 4 and a linkage assembly, wherein the fixed block 2 and the adjusting block 3 are both provided with two and symmetrically arranged on the top of the support plate 1, the threaded rod 4 is fixed between the fixed block 2 and the adjusting block 3, and a linkage assembly is arranged inside the support plate 1;

[0027] The linkage assembly includes two rotating rods 7, two first gears 8, a second gear 9 and a motor 10. The two rotating rods 7 are symmetrically distributed inside the support plate 1. The two first gears 8 are respectively fixed with the middle bolts of the two rotating rods 7. The second gear 9 is meshed with the two first gears 8. The output end of the motor 10 is fixed with the middle bolt of the first gear 8.

[0028] In this embodiment, the fixed block 2 is composed of a fixed plate 201, an adjustment plate 202 and two sliding feet 203. The adjustment plate 202 is welded to one side of the fixed plate 201. The side of the adjustment plate 202 away from the fixed plate 201 is set as a first inclined surface, and baffles are set on both sides.

[0029] It is currently explained that, through the cooperation between the first inclined surface of the adjustment plate 202 and the second inclined surface of the adjustment block 3, a stable clamping environment is provided for the workpiece, and the baffles arranged on both sides can effectively prevent the workpiece from sliding sideways during the clamping process, thereby ensuring the stability and safety of the clamping.

[0030] In this embodiment, one side of the adjustment block 3 is set as a second inclined surface with the same inclination angle as the first inclined surface, and is in contact with the first inclined surface. A runway-shaped through hole 301 is opened on the top of the adjustment block 3, and a threaded groove 204 is opened on the top of the first inclined surface. The threaded rod 4 passes through the runway-shaped through hole 301 and is fixed with bolts on the threaded groove 204.

[0031] It should be noted that the design of the racetrack-shaped through hole 301 on the adjusting block 3 allows the threaded rod 4 to be adjusted within a certain range to meet the clamping requirements of workpieces of different widths.

[0032] In this embodiment, a slide groove 5 is provided on the top of the support plate 1 , and the slide foot 203 is welded to the fixed plate 201 and is slidably connected to the slide groove 5 .

[0033] It should be noted that the slide groove 5 on the support plate 1 provides a stable sliding track for the slide foot 203, ensuring the smooth movement of the fixed block 2 and the adjustment block 3 in the horizontal direction.

[0034] In this embodiment, the rotating rod 7 is provided with two sections of threads in opposite directions on the outside, and the threads are respectively connected to the two sliding feet 203 .

[0035] It should be noted that when the rotating rod 7 rotates, due to the opposite directions of the threads, the two sliding feet 203 will move in opposite directions, thereby driving the fixing block 2 and the adjusting block 3 to perform clamping or loosening operations.

[0036] In this embodiment, an adjustment slot 6 is provided at the bottom of the support plate 1, and the linkage components are all located inside the adjustment slot 6. The top of the motor 10 is fixed to the top of the adjustment slot 6 with bolts.

[0037] In this embodiment, no threads are provided at the middle and both ends of the rotating rod 7, and the first support frame 11 and the second support frame 12 are rotatably connected through bearings respectively. The tops of the first support frame 11 and the second support frame 12 are fixed with the top bolts of the adjustment slot 6.

[0038] It should be noted that the adjustment slot 6 at the bottom of the support plate 1 provides sufficient installation space for the linkage assembly, ensuring the compact layout and stable operation of the various components. The first support frame 11 and the second support frame 12 are connected to the rotating rod 7 through bearings, which not only enhances the stability of the rotating rod 7, but also reduces friction and wear, thereby extending the service life of the clamp. At the same time, the top of the support frame is fixed to the top of the adjustment slot 6 by bolts, further enhancing the stability of the entire clamp structure.

[0039] Working principle:

[0040] According to the width of the workpiece to be processed, the motor 10 is started to drive the second gear 9, the first gear 8 and the two rotating rods 7 to rotate in sequence. Since the rotating rod 7 is provided with two sections of threads in opposite directions on the outside, and they are respectively threadedly connected with the sliding feet 203 on both sides, the sliding feet 203 are driven to move in the horizontal direction, and then the adjusting block 3 and the fixed block 2 are driven to move in the horizontal direction. After adjusting to the appropriate position, the motor 10 is turned off, and then the fixed block 2 is pushed downward by tightening the threaded rod 4. While the fixed block 2 moves downward along the second inclined surface, the other side squeezes the workpiece to be processed, thereby clamping the workpiece.

[0041] Beneficial effects:

[0042] The machine tool fixture adjusts the clamping force by matching the first inclined surface on the adjusting plate 202 of the fixed block 2 with the second inclined surface of the adjusting block 3, and then passing the threaded rod 4 through the track-shaped through hole 301 of the adjusting block 3 and connecting with the threaded groove 204 of the fixed block 2. The motor 10 drives the second gear 9 to rotate, thereby driving the two first gears 8 to rotate, and then driving the rotation of the two rotating rods 7. Since the rotating rod 7 is provided with two sections of threads in opposite directions on the outside, and they are respectively threadedly connected with the sliding feet 203 of the fixed block 2, the rotation of the rotating rod 7 will drive the sliding feet 203 to slide in the sliding groove 5 of the support plate 1, thereby realizing the horizontal movement of the fixed block 2 and the adjusting block 3. This design enables the fixture to be quickly and accurately adjusted according to the width of the workpiece, and ensures that the workpiece is kept in the middle of the support plate 1 when clamping the workpiece after adjustment, thereby improving the subsequent processing accuracy.

[0043] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
