[0002] A hinge is a device that allows a door to rotate naturally and smoothly to open and close. A door hinge consists of a hinge seat and a hinge body. One end of the hinge body is connected to the door frame through a mandrel, and the other end is connected to the door leaf. Since the hinge body is divided into two sections and connected as a whole through a connecting plate, the door leaf can be removed for repair by removing the connecting plate. A fixture is a device used to fix the processing object in the mechanical manufacturing process so that it occupies the correct position for construction or inspection. It is also called a fixture. In a broad sense, any device used to quickly, conveniently and safely install a workpiece in any process in the process can be called a fixture.

[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] Example 1

[0023] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a hinge processing fixture, including a base 1, bottom plates 2 are symmetrically arranged at both ends of the top of the base 1, a bracket 3 is fixedly connected to one end of the top of the bottom plate 2, a fixing frame 4 is arranged on one side of the bracket 3, a motor 5 is arranged on the top of the fixing frame 4, the output end of the motor 5 movably passes through the fixing frame 4 and is connected to a screw rod 6, a connecting plate 7 is arranged on the outer side of the screw rod 6, a pressure plate 9 is connected to the bottom of the connecting plate 7, and two fastening bolts 8 are installed on the top of the connecting plate 7.

[0024] In this embodiment, the motor 5 drives the screw rod 6 to rotate, causing the connecting plate 7 to slide on the screw rod 6, thereby driving the pressure plate 9 to move up and down to adjust the height. The fastening bolts 8 can be used to fix the pressure plate 9 and the connecting plate 7 together, thereby increasing the connection strength between the two, thereby achieving flexible adjustment of the height of the pressure plate 9, and then adapting to clamping hinges of different thicknesses, effectively improving the versatility of the clamp, while also improving the stability of clamping to meet different usage requirements.

[0025] Example 2

[0026] like Figure 1-Figure 4 As shown, a slide groove 10 is provided on the top of the base 1, and cylinders 11 are symmetrically provided at both ends of the base 1. The output end of the cylinder 11 movably passes through the base 1 and is connected to a slider 12. The top of the slider 12 is connected to the bottom plate 2. The slider 12 is provided on the inner side of the slide groove 10, and a guide rod 13 is provided on the inner side of the slide groove 10. The slider 12 is movably installed on the outer side of the guide rod 13. A rubber anti-skid pad 14 is provided on the top of the bottom plate 2, and countersunk bolts 15 are installed at the four corners of the top of the rubber anti-skid pad 14. Two groups of mounting seats 16 are symmetrically provided on both sides of the base 1, and a notch 17 is provided on the surface of the mounting seat 16. A mounting bolt 18 is provided on the inner side of the mounting seat 16, and a gasket 19 is sleeved on the outer side of the mounting bolt 18.

[0027] In this embodiment, two cylinders 11 are used to push the corresponding sliders 12 to slide in the slide groove 10, thereby adjusting the distance between the two brackets 3, so as to clamp and fix hinges of different sizes and lengths, thereby improving the clamping effect, improving the stability of the hinge during later processing, and improving the overall work efficiency. The slider 12 can limit the guide rod 13, and at the same time maintain the stability of the slider 12 when it moves, to prevent the slider 12 from shaking and causing the clamping effect of the clamp to deteriorate. The countersunk bolt 15 can fix the rubber anti-skid pad 14 on the bottom plate 2 and keep its surface flat, thereby preventing the rubber anti-skid pad 14 is loose, and the rubber anti-skid pad 14 can increase the friction force to prevent the hinge from sliding off due to vibration during processing. At the same time, the hinge is protected to prevent the hinge from being damaged due to excessive clamping force. The mounting seat 16 can increase the friction force between the base 1 and the processing equipment to prevent the vibration generated by the hinge processing from causing the fixture to shake, thereby improving the clamping effect and stability and ensuring the normal progress of the hinge processing. The base 1 can be installed and fixed on the hinge processing equipment by installing the bolts 18, and the gasket 19 can be used to increase the friction force, which can effectively prevent the mounting bolts 18 from loosening, thereby improving the stability of the fixture during the hinge processing process.

[0028] The working principle of this embodiment: when in use, first place the base 1 on the hinge processing equipment, tighten the mounting bolts 18 to install and fix it, then start the two cylinders 11, and simultaneously push the corresponding sliders 12 to slide inside the slide groove 10, adjust the distance between the two brackets 3 to adapt to the size and length of the hinge to be clamped, and finally place the hinge to be processed on the rubber anti-slip pad 14, and start the two motors 5 at the same time to drive the corresponding screw rods 6 to rotate, so that the connecting plate 7 drives the pressure plate 9 to press down, and the hinge is clamped and fixed, thereby completing the use of the hinge processing fixture.

[0029] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
