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.

[0026] Embodiment 1, as Figure 1-Figure 5 As shown, the utility model provides a mechanical parts processing fixture, including a clamping mechanism 1, and a lifting mechanism 2 is fixedly installed at the bottom of the clamping mechanism 1;

[0027] The clamping mechanism 1 includes a support plate 101, a slide groove 102 is provided on the top of the support plate 101, a group of first holes 103 are provided on the outer wall of the support plate 101, a bidirectional threaded rod 104 is movably inserted between the inner wall of the group of first holes 103, a first adjusting wheel 105 is fixedly installed on one side of the outer wall of the bidirectional threaded rod 104, four support legs 106 are fixedly installed on the bottom of the support plate 101, the outer wall of the bidirectional threaded rod 104 is rotatably connected to two sliders 107, and the outer walls of the two sliders 107 are movably embedded with the inner wall of the slide groove 102, and the tops of the two sliders 107 are fixedly installed with the outer wall of the two sliders 107. A fixing plate 108 is fixedly installed at the bottom of each of the two fixing plates 108, a group of first threaded holes 109 are opened on the top of each of the two fixing plates 108, a group of fixing screws 110 are rotatably connected to the inner surface walls of the two groups of first threaded holes 109, a clamping block 111 is rotatably connected between the outer surface walls of the two groups of fixing screws 110, a second threaded hole 112 is opened on the top of each of the two clamping blocks 111, a threaded column 114 is rotatably connected to the inner surface walls of the two second threaded holes 112, a second adjusting wheel 113 is fixedly installed on the top of each of the two threaded columns 114, and an extrusion plate 115 is fixedly installed on the bottom of each of the two threaded columns 114.

[0028] The effect achieved by the entire embodiment 1 is that when the clamp cannot fix the mechanical parts well, it is only necessary to rotate and twist the two sets of fixing screws 110 to remove the two clamping blocks 111, and then the appropriate clamping blocks 111 can be fixed on the two clamping blocks 111 through the two sets of fixing screws 110 according to the size of the metal parts, thereby increasing the functionality and adaptability of the clamp, and one clamp can meet multiple fixing requirements, and can also save costs. Then the mechanical parts can be placed on the support plate 101, and the first adjusting wheel 105 is rotated to drive the bidirectional threaded rod 104 to rotate, so that the two sliders 107 are close to each other inside the slide groove 102, and the two sliders 107 will drive the two clamping blocks 111 to move closer to each other through the two fixing plates 108 on the top, clamping and fixing the mechanical parts, and then the two second adjusting wheels 113 are rotated to make the two extrusion plates 115 rotate downward to fix the mechanical parts. Multi-directional fixation can increase the fixing effect and prevent the metal parts from loosening during processing.

[0029] Embodiment 2, as Figure 2-Figure 5As shown, the lifting mechanism 2 includes two support columns 201, the inner walls of the two support columns 201 are movably inserted with worm gears 202, the outer walls of the two support columns 201 are fixedly installed with shells 203, the outer walls of the two shells 203 are each provided with a group of second holes 204, a rotating shaft 205 is movably inserted between the inner walls of the two groups of second holes 204, a motor 207 is fixedly installed on one side of the outer wall of one of the two shells 203, and the output end of the motor 207 is fixedly connected to one side of the outer wall of the rotating shaft 205, two worm gears 206 are fixedly sleeved on the outer wall of the rotating shaft 205, and the outer walls of the two worm gears 206 are meshed with the inner walls of the worm gear 202, and the bottom of the support plate 101 is fixedly connected to the tops of the two worm gears 202.

[0030] The effect achieved by the entire embodiment 2 is that when the height of the mechanical parts needs to be adjusted, the motor 207 can be started to drive the rotating shaft 205 to start rotating. When the rotating shaft 205 rotates, the two worm gears 206 fixedly mounted on its outer wall will drive the two worms 202 to rise, and then drive the mechanical parts to rise. By adjusting the height, the practicality of the device can be increased, and workers of different heights and body shapes can be prevented from feeling inconvenienced when working, and bad working postures can be prevented from damaging the health of workers.

[0031] Working principle: When it is necessary to fix the mechanical parts, it is only necessary to place the mechanical parts on the support plate 101 first, and then rotate the first adjusting wheel 105. The first adjusting wheel 105 will drive the bidirectional threaded rod 104 to rotate inside a group of first holes 103. When the bidirectional threaded rod 104 rotates, it will drive the two sliders 107 to slide close to each other inside the slide groove 102 through the surface threads. When the two sliders 107 slide, they will drive the two fixing plates 108 on the top to move together. The two fixing plates 108 will make the two fixing screws 110 make the two fixing screws 110 The clamping blocks 111 are brought close to each other to clamp and fix the mechanical parts. Then, the two second adjusting wheels 113 can be rotated to make the two threaded columns 114 rotate and move downward inside the two second threaded holes 112, driving the two extrusion plates 115 to fix the mechanical parts. After the mechanical parts are fixed, the motor 207 can be started according to user needs. The motor 207 can drive the rotating shaft 205 to move together. When the rotating shaft 205 rotates, it will drive the two worm wheels 206 to rotate together, so that the two worms 202 rise and lift the support plate 101.
