[0001] The utility model belongs to the technical field of hardware processing, in particular to an adjustable clamp for hardware processing. Background Art
[0002] Traditional hardware refers to objects made of five metals: gold, silver, copper, iron, and tin. They are very common in life. When processing hardware, clamps are usually used to clamp and fix the hardware in order to ensure the stability of the processing.
[0003] Existing clamps are generally composed of screws and splints. The splints generally have a certain shape, but the shapes of hardware vary. When clamping some special-shaped hardware, the shape of the splint does not match the hardware, resulting in fewer force points on the hardware and unstable clamping, which affects the processing accuracy. Utility Model Content
[0004] In order to overcome the above-mentioned defects, the utility model provides an adjustable clamp for hardware processing, which solves the problem that when the existing clamps clamp some special-shaped hardware, the shape of the clamping plate does not match the hardware, resulting in fewer force points on the hardware and unstable clamping, thus affecting the processing accuracy.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an adjustable fixture for hardware processing, comprising a bottom plate, a fixed block is fixedly connected to the top of the bottom plate, a rotating plate is hinged on the fixed block, two clamping plates are slidably connected to the top of the rotating plate, a box body is provided on one side of the clamping plate, a threaded rod is rotatably connected to one side of the box body, and a screw rod is threadedly connected to the box body;
[0006] One end of the screw rod is rotatably connected to a moving block, two connecting rods are hinged on the moving block, a moving rod is hinged on the connecting rod, a limiting rod is fixedly connected to the moving rod, two moving rods are slidably connected to a fixed rod, two grooves are provided on the clamping plate, and two limiting holes are provided on the clamping plate.

[0011] As a further solution of the utility model: one end of the worm is fixedly connected to a second nut, and one end of the screw is fixedly connected to a rotating column.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] 1. The adjustable hardware processing clamp is provided with a screw rod, a connecting rod, a moving rod, a limit rod and a second nut. When it is necessary to replace a splint of a different shape, the rotating column is rotated to drive the screw rod to rotate, so that the moving block moves downward. When the moving block moves downward, the two moving rods and the limit rod are pushed away from each other by the connecting rod. At the same time, the limit rod is disengaged from the inside of the limit hole, and the limit fixation of the splint is released. The splint can be disassembled and replaced with a splint of a different shape. When installing the splint, it is only necessary to repeat the above operation in reverse. The clamp is convenient for replacing splints of different shapes, so that the shape of the splint is easy to match with special-shaped hardware, thereby improving the clamping stability and avoiding affecting the processing accuracy.
[0014] 2. The adjustable hardware processing fixture is provided with a worm, a worm wheel, a second nut, and a rotating plate. When in use, the hardware is placed between the two clamping plates, and the first nut is rotated to drive the threaded rod to rotate, so that the box body and the clamping plate move, and the clamping plate clamps and fixes the hardware. When the angle of the hardware needs to be adjusted, the second nut is rotated to drive the worm, the worm wheel, the rotating rod and the rotating plate to rotate, so as to complete the angle adjustment of the hardware. The fixture is convenient for adjusting the angle of the hardware, and is convenient for the processing device to process the hardware at different angles. In addition, the worm and the worm wheel have a self-locking function, which improves the stability of the angle adjustment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0020] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.
[0021] like Figure 1-4 As shown, the utility model provides a technical solution: an adjustable hardware processing fixture, including a base plate 1, a fixed block 2 is fixedly connected to the top of the base plate 1, a rotating plate 4 is hinged on the fixed block 2, two clamping plates 10 are slidably connected to the top of the rotating plate 4, and four mounting holes 3 are opened on the base plate 1. Because the mounting holes 3 are U-shaped, when the base plate 1 is installed on the processing equipment, it is possible to prevent the mounting holes 3 from being misaligned with the threaded holes on the processing equipment, thereby facilitating personnel to install the base plate 1, thereby facilitating personnel to install the base plate 1. A waterproof box 5 is fixedly connected to the top of the base plate 1. Because the waterproof box 5 is provided, the waterproof box 5 can isolate moisture in the air, prevent the worm wheel 14 and the worm 12 from getting damp and rusting, and play a waterproof role.
[0022] A box body 7 is provided on one side of the splint 10, and a threaded rod 8 is rotatably connected to one side of the box body 7. A screw rod 15 is threadedly connected to the box body 7, and a moving block 17 is rotatably connected to one end of the screw rod 15. The threaded rod 8 is threadedly connected to the rotating plate 4, and a plastic pad 11 is fixedly connected to the splint 10. Because of the plastic pad 11, when the splint 10 clamps the hardware, the plastic pad 11 can protect the hardware, reduce the wear of the hardware caused by the splint 10, and improve product quality.
[0023] Two connecting rods 18 are hinged on the moving block 17, a moving rod 19 is hinged on the connecting rod 18, a limiting rod 20 is fixedly connected to the moving rod 19, a fixed rod 21 is slidably connected to the two moving rods 19, a worm 12 is rotatably connected to the waterproof box 5, and a worm wheel 14 is meshed on the worm 12.
[0024] Two grooves 22 are provided on the splint 10, two limit holes 23 are provided on the splint 10, a rotating rod 6 is fixedly connected to the worm wheel 14, a first nut 9 is fixedly connected to one end of the threaded rod 8, and a second nut 13 is fixedly connected to one end of the worm 12. Since a plurality of grooves are provided on the second nut 13, friction can be increased, which makes it easier for personnel to rotate the second nut 13 and improves operational convenience. A rotating column 16 is fixedly connected to one end of the screw rod 15.
[0025] The working principle of the utility model is:
[0026] When in use, place the hardware between the two clamping plates 10, rotate the first nut 9 to drive the threaded rod 8 to rotate, so that the box body 7 and the clamping plate 10 move, and the clamping plate 10 clamps and fixes the hardware. When the angle of the hardware needs to be adjusted, rotate the second nut 13 to drive the worm 12, the worm wheel 14, the rotating rod 6 and the rotating plate 4 to rotate, and the angle adjustment of the hardware is completed;
[0027] When it is necessary to replace the splint 10 with a different shape, the rotating column 16 is rotated to drive the screw 15 to rotate, so that the moving block 17 moves downward. When the moving block 17 moves downward, the two moving rods 19 and the limiting rod 20 are pushed away from each other through the connecting rod 18. At the same time, the limiting rod 20 is disengaged from the inside of the limiting hole 23, and the limiting fixation of the splint 10 is released. The splint 10 can be disassembled and replaced with a splint 10 of a different shape. When installing the splint 10, you only need to repeat the above operation in reverse.
