[0004] The positioning auxiliary device for metal workpiece processing in the above-mentioned patent has the following shortcomings: when processing existing metal workpieces, the auxiliary mechanism is mostly a clamping and fixing structure to achieve precise clamping of the workpiece, but in the process of processing the workpiece, since the workpiece needs to be processed as a whole, the position of the workpiece needs to be manually adjusted many times, and automatic adjustment during processing cannot be achieved, resulting in low processing efficiency. Utility Model Content

[0029] Example:

[0030] Reference Figure 1 、 Figure 2 、 Figure 6 , a metal workpiece processing auxiliary mechanism includes an adjusting plate 1 and a processing plate 2 slidably connected to the adjusting plate 1, a bracket 25 is fixedly installed on the processing plate 2, a slide groove 11 is provided on both sides of the adjusting plate 1, two sliders 21 are fixedly installed on both sides of the bottom of the processing plate 2, the sliders 21 are slidably installed inside the slide grooves 11, and the slide grooves 11 provided on both sides of the adjusting plate 1 allow the processing plate 2 to be adjusted in the horizontal direction through the sliders 21. This design increases the flexibility of the processing plate 2, so that the operator can easily adjust the position of the processing plate 2 according to the size of the workpiece and processing requirements. An adjusting groove 26 is provided on the processing plate 2, which is a space for the push plate 22 to move. A push plate 22 is movably installed inside the adjusting groove 26, and top plates 24 are fixedly connected on both sides of the push plate 22. The top plate 24 is arranged on the outside of the slider 21, and the top plate 24 abuts against the slide groove 11. A number of supporting springs 23 are fixedly connected to the push plate 22, and the free ends of the supporting springs 23 are fixedly connected to the inside of the adjusting groove 26. The elasticity provided by the supporting springs 23 makes the slider 2 fit tightly into the inside of the slide groove 11, and the movement of the processing plate 2 is limited. Through the free movement of the processing plate 2, the processing plate 2 is moved out of the processing equipment for loading before processing, and it is convenient to move to the processing equipment after loading to limit the movement of the processing plate 2.

[0031] Reference Figures 1-4 The support 25 is fixedly connected to the processing plate 2, wherein a hollow rod 41 is rotatably connected in the support 25, and the hollow rod 41 passes through the support 25 and extends to the top and is fixedly connected to the mounting head 42, and the mounting head 42 is rotatably connected with a clamping claw, which is used to clamp the workpiece; the rotating shaft 33 rotatably connected to the hollow rod 41, wherein the axis of the hollow rod 41 coincides with the axis of the rotating shaft 33, the rotating shaft 33 passes through the mounting head 42 and extends to the top, and the rotating shaft 33 rotates with the upper clamping plate 5; the driving part is used to drive the hollow rod 41 and the rotating shaft 33 to rotate, and the hollow rod 41 serves as the support and transmission component of the upper clamping system, and at the same time allows the rotating shaft 33 to pass through its interior to realize the linkage of the upper and lower clamping systems, the mounting head 42 is a concave structure, and a rotating rod 43 is rotatably installed on the mounting head 42, and the clamping claw is fixedly connected to the rotating rod 43, and the rotating rod 43 is fixedly connected to a linkage bevel gear 44, which rotates in coordination with the rotating shaft 33. The upper end of the worm gear 31 is meshed with the upper worm gear 4, and the upper worm gear 4 is fixedly connected to the lower end of the hollow rod 41, and the lower worm gear 32 is meshed with the lower worm gear 32, and the lower worm gear 32 is fixedly connected to the lower end of the rotating shaft 33. Through the cooperation between the worm gear 31 and the two worm gears, not only the purpose of multi-angle adjustment of the metal workpiece to be processed on the clamping jaw can be achieved, but also the self-locking function can be achieved after the angle adjustment.

[0032] Reference Figure 5 The clamping jaws include an upper clamping plate 5, which is fixedly connected to the outer side of the rotating rod 43, and a piston rod 52 is slidably installed inside the upper clamping plate 5.

The return spring 53 is arranged inside the upper clamping plate 5, and the piston rod 52 can perform linear motion inside the upper clamping plate 5, thereby driving the lower clamping plate 51 to move closer to or away from the upper clamping plate 5, thereby clamping or releasing the workpiece. When the lower clamping plate 51 approaches the upper clamping plate 5 under the drive of the piston rod 52, the two jointly form a clamping force on the workpiece, and the return spring 53 is sleeved on the outer wall of the piston rod 52. The return spring 53 provides clamping force for the lower clamping plate 51, so that when the workpiece is placed between the upper clamping plate 5 and the lower clamping plate 51, the purpose of adjusting the clamping of metal parts of different sizes is achieved.

[0033] Before processing the metal workpiece, first place the workpiece between the upper clamping plate 5 and the lower clamping plate 51 to clamp and fix it. After the fixation is completed, push the push plates 22 on both sides and adjust the position of the workpiece according to the corresponding processing mechanism of the processing plate 2 according to the size of the workpiece. After the adjustment is completed, release the push plates 22 on both sides, and the elasticity of the support spring 23 allows the top plate 24 to apply force to the inner wall of the slide groove 11 to fix the processing plate 2.

[0034] Secondly, during processing, by rotating the upper worm 31, the workpiece can be rotated around the hollow rod 41 as the axis, thereby adjusting the processing position of the workpiece. When the lower worm 31 rotates, the workpiece rotates around the rotating rod 43 as the axis. By controlling the rotation of the two worms 31 separately, the free rotation of the workpiece is achieved, and the processing angle of the workpiece can be freely adjusted during processing, thereby improving processing efficiency.
