The vertical plate 6 also includes a rectangular through hole 16. A rectangular through-hole 16 extends between the two sides of the vertical plate 6. A sliding plate 17 is slidably installed within the rectangular through-hole 16. The second electric cylinder 7 is fixedly installed on one side of the sliding plate 17. A second lead screw 18 is fixedly installed on the top of the sliding plate 17. A cylinder 19 is fixedly installed on the top of the vertical plate 6. An internally threaded cylinder 20 is rotatably installed inside the cylinder 19. The second lead screw 18 threadedly passes through the corresponding internally threaded cylinder 20. A first bevel gear 21 is fixedly sleeved on the internally threaded cylinder 20. A second motor 22 is provided on one side of the vertical plate 6. A second bevel gear 23 meshing with the first bevel gear 21 is provided on the output shaft of the second motor 22. This arrangement facilitates the adjustment of the position of the second electric cylinder 7, thereby facilitating the adaptation to different irregularly shaped workpieces 4. This greatly facilitates the clamping and positioning of the irregularly shaped workpiece 4. A first through hole is formed on the top inner wall of the chamber 8, through which the rotating shaft 9 rotates. The first through hole facilitates support and positioning of the rotating shaft 9. The operating table 3 is a box-shaped structure with openings on both sides. The first electric cylinder 5 is fixedly installed on the top inner wall of the operating table 3.

Two clamping plates are fixedly installed inside the chamber 8. The first lead screw 12 rotates through the two clamping plates, and the first motor 14 is fixedly installed on the corresponding clamping plates.This facilitates the support and limiting of the first lead screw 12. Multiple third through holes are provided on the slide plate 17, through which the output rod of the second electric cylinder 7 slides. Sliding grooves are provided on both inner walls of the rectangular through hole 16, and sliders are slidably installed within these grooves. The sliders are fixed to one end of the slide plate 17. The third through holes facilitate the extension and retraction of the output rod of the second electric cylinder 7. A fourth through hole is provided on the top inner wall of the rectangular through hole 16, through which the second lead screw 18 passes.

Contact plates are fixedly installed on the output rods of the first electric cylinder 5 and the second electric cylinder 7, and these contact plates contact the irregularly shaped workpiece 4. The support plate facilitates the installation and fixation of the second motor 22.

[0037] The working principle of this utility model is as follows: In use, the irregularly shaped workpiece 4 is first placed on top of the operating table 3. Then, multiple first motors 5 are turned on, and the output rods of the first motors 5 extend, lifting the irregularly shaped workpiece 4 and placing it in a horizontal position. Next, two second motors 22 are turned on. The output shafts of the second motors 22 drive the second bevel gear 23 to rotate, which in turn drives the corresponding first bevel gear 21 to rotate. The first bevel gear 21 drives the internal threaded cylinder 20 to rotate, which in turn drives the second lead screw 18 to rise and fall. The second lead screw 18 drives the slide plate 17 to slide and rise and fall within the rectangular through hole 16, adjusting the height of the multiple second electric cylinders 7 to a suitable level. Then, the multiple second electric cylinders 7 are turned on, and the output rods of the second electric cylinders 7 press against the irregularly shaped workpiece 4, clamping and fixing it. Then, the CNC machining assembly 2 can be turned on to process the irregularly shaped workpiece 4. This setup facilitates the processing of the workpiece. The position of the second electric cylinder 7 is adjusted to better accommodate different irregularly shaped workpieces 4, greatly facilitating the clamping and positioning of these workpieces. When the irregularly shaped workpiece 4 needs to be rotated, the first motor 14 is turned on. The output shaft of the first motor 14 drives the third gear 15 to rotate, which in turn drives the second gear 13 to rotate. The second gear 13 then drives the first lead screw 12 to rotate, causing the rack 11 to slide laterally on the top inner wall of the chamber 8. This causes the first gear 10 to rotate, which in turn drives the rotating shaft 9 to rotate, causing the operating table 3 to rotate. The operating table 3 then rotates the irregularly shaped workpiece 4 by a certain angle. This arrangement facilitates the rotation and adjustment of the irregularly shaped workpiece 4, making it easier to adjust its processing position and to observe the processing status, thus greatly facilitating the processing of irregularly shaped workpieces.
