DETAILED DESCRIPTION
[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.
[0023] Reference Figure 1-Figure 4 The cam 6 is provided with two camshafts 6 at the bottom, and a guide groove 7 is provided on one side of the cam 6, and a worm 10 is movably connected in the guide groove 7. An adjusting component for driving the cam 5 to rotate and a power mechanism for driving the movable plate 3 to move are provided in the cavity 12. A positioning mechanism for fixing the position of the worm 10 is provided at one end of the worm 10. The angle of the cam 5 is adjusted by the adjusting component, and the position of the cam 5 is changed by the power mechanism, so as to realize the adjustment of the position of the brake bracket placed in the cam 6. Different processing requirements can be met without disassembling the brake bracket, so as to improve the processing efficiency of the brake bracket.
[0024] Among them, the adjustment component includes a connecting shaft 21, which is fixed to the bottom outer wall of the placement frame 5 by bolts. One end of the connecting shaft 21 is keyed to a worm wheel 9, and the worm 10 can be used in conjunction with the worm wheel 9. A avoidance groove 16 is provided on the top of the base 1, and the connecting shaft 21 passes through the avoidance groove 16. When the worm 10 is engaged with the worm wheel 9, the worm 10 is rotated, thereby driving the worm wheel 9 to rotate, and then the placement frame 5 is rotated, thereby changing the angle of the brake bracket on the placement frame 5, and improving the applicability of the clamp. The power mechanism includes two connecting frames 13, and the two connecting frames 13 are symmetrically distributed on the lower surface of the movable plate 3. Two slide grooves are provided on the top of the base 1 11, and the two connecting frames 13 slide in the two slide grooves 11 respectively, and the opposite sides of the two connecting frames 13 are provided with threaded grooves 14, and a threaded rod 15 is welded at one end of the worm 10, and the threaded rod 15 and the threaded groove 14 can be used in conjunction with each other. When the threaded rod 15 is engaged with the threaded groove 14, the worm 10 is rotated, thereby driving the threaded rod 15 to rotate, and then the movable plate 3 and the placement frame 5 move synchronously, meeting the lateral adjustment of the brake bracket, and further improving the applicability of the clamp. The positioning mechanism includes a slider 8, which is rotatably connected to the outer side of the circumference of the worm 10, and the slider 8 is in contact with the base 1, and a sliding hole 17 is provided on one side of the slider 8. The sliding hole 17 is provided on the one side of the slider 8. An elastic component 19 is provided on the inner wall of one side of the cavity 12. The elastic component 19 can be a spring, elastic rubber, etc. A card bead 18 is provided on the other end of the elastic component 19. The card bead 18 moves in the slide hole 17. Two arc-shaped grooves 20 are provided on the inner wall of one side of the cavity 12, and the card bead 18 is located in one of the arc-shaped grooves 20. When the position of the worm 10 is adjusted, the worm 10 is pushed to move, and the worm 10 drives the slide block 8 to move synchronously, so that the arc-shaped groove 20 squeezes the card bead 18 to move into the slide hole 17, and then the slide block 8 and the slide hole 17 can move synchronously. When the card bead 18 moves to the other arc-shaped groove 20, the compressed elastic component 19 is reset. At this time, the elastic component 19 will squeeze the card bead 18 into the arc groove 20, thereby completing the fixation of the position of the slider 8 and the worm 10, and then completing the function selection. One end of the worm 10 is fixed with a turning handle 2 by a bolt. Two scales 4 are provided on the top of the base 1, and the two scales 4 are used in conjunction with the moving plate 3. The moving distance of the moving plate 3 can be clearly observed. Friction blocks are bonded to both ends of the bottom of the moving plate 3, and the friction blocks are in contact with the base 1, increasing the friction between the moving plate 3 and the base 1, preventing the moving plate 3 from easily moving when the threaded rod 15 is out of contact with the threaded groove 14, so that the moving plate 3 can be stably fixed.
[0025] Finally, it should be noted that: for those skilled in the art, they can still modify the technical solutions recorded in the above embodiments, or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of this utility model shall be included in the protection scope of this utility model.
