[0022] When working, the hinge, as a mechanical device, is designed to connect two solids and allow them to rotate relative to each other. Hinges are widely used, including doors and windows, furniture and other fields. When hinges are processed and produced, they need to be fixed with a processing fixture to facilitate many subsequent processing operations of the hinges; the hinge processing fixture is generally composed of a clamping component and a fixing component. The hinge to be processed is placed within the action range of the clamping component, and the hinge is clamped and fixed with the fixing component, thereby achieving smooth processing of the hinge; due to the use requirements in different environments, hinges of different specifications and sizes have emerged, but the clamping effect of the existing hinge processing fixture is single, and cannot meet the clamping and fixation of hinges of various shapes and sizes. It takes a lot of time to replace the corresponding fixture, which affects the speed of hinge processing. Place the workpiece between the clamping blocks 4 at both ends, start the motor 12, drive the transmission shaft 13 to rotate, and the bidirectional screw 14 rotates accordingly, driving the moving block 15 to move, and then the clamping blocks 4 at both ends move toward the middle, and at the same time, the comb teeth 6 initially clamp the workpiece, start the cylinder 9, and the telescopic rod 10 starts to work, pushing the push plate 11, and the steel ball 8 moves toward the direction of the comb teeth 6 to further clamp the workpiece. At the same time, the cross bar 18 installed in the waist hole 17 moves with the movement of the comb teeth 6, driving the connecting blocks 19 installed at both ends of the cross bar 18 to move accordingly, so that the spring 20 is stretched. It meets the clamping and fixing of hinges of various shapes and sizes, and does not need to spend a lot of time to replace the corresponding clamps, so that the hinge processing efficiency is improved.

[0024] During operation, after the processing is completed, the cylinder 9 stops working, the telescopic rod 10 contracts, and the push plate 11 moves. At the same time, the spring 20 installed on the fixed seat 21 contracts due to the reaction force, driving the connecting block 19 to pull back, and the cross bar 18 arranged in the waist hole 17 is pulled back accordingly. When the cross bar 18 is pulled back, it drives the comb teeth to return to the initial position.
[0025] Working principle: As a mechanical device, hinges are designed to connect two solids and allow them to rotate relative to each other. Hinges are widely used in doors and windows, furniture and other fields. When hinges are processed and produced, they need to be fixed with processing fixtures to facilitate the subsequent processing of hinges. Hinge processing fixtures are generally composed of clamping components and fixing components. The hinge to be processed is placed within the range of action of the clamping components, and the hinge is clamped and fixed with fixing components to achieve smooth processing of the hinge. Place the workpiece between the clamping blocks 4 at both ends, start the motor 12, drive the transmission shaft 13 to rotate, and the bidirectional screw 14 rotates accordingly, driving the moving block 15 to move, and then the clamping blocks 4 at both ends move toward the middle, and at the same time, the comb teeth 6 initially clamp the workpiece, start the cylinder 9, and the telescopic rod 10 starts to work, pushing the push plate 11, and the steel ball 8 moves toward the direction of the comb teeth 6 to further clamp the workpiece. At the same time, the cross bar 18 installed in the waist hole 17 moves with the movement of the comb teeth 6, driving the connecting blocks 19 installed at both ends of the cross bar 18 to move accordingly, so that the spring 20 is stretched. After the processing is completed, the cylinder 9 stops working, the telescopic rod 10 contracts, and drives the push plate 11 to move. At the same time, the spring 20 installed on the fixed seat 21 contracts due to the reaction force, driving the connecting block 19 to pull back, and the cross bar 18 set in the waist hole 17 is pulled back accordingly. When the cross bar 18 is pulled back, the comb teeth are driven back to the initial position. This technology meets the clamping and fixing of hinges of various shapes and sizes, and does not need to spend a lot of time to replace the corresponding clamps, so that the hinge processing efficiency is improved.
