[0034] The outer wall of the screw rod 23 is provided with a movable telescopic rod 24, the other end of the telescopic rod 24 is connected to a cutting host 25, and the lower end of the cutting host 25 is provided with a laser cutting head 251. This design can perform cutting processing on forgings.

[0035] The telescopic rod 24 is provided with a screw hole 241 engaged with the screw rod 23 , and this design enables the telescopic rod 24 to move up and down.

[0036] The rotation adjustment assembly 3 includes a screw rod 31 rotatably installed in the slide groove 11 . The screw rod 31 passes through the right end of the workbench 1 and is provided with a rotating disk 32 . Rotating the rotating disk 32 can drive the screw rod 31 to rotate.

[0037] The clamping assembly 4 includes a base 41 , a sliding seat 42 is provided on the lower end surface of the base 41 , the sliding seat 42 is installed on the outer wall of the screw rod 31 , and is provided with a thread groove 421 engaged with the screw rod 31 , and the sliding seat 42 can drive the base 41 to slide.

[0038] The left end face of the base 41 is provided with an inwardly recessed stabilizing hole 411, the left end of the base 41 is provided with a rotatable sleeve 43, and the sleeve 43 is provided with a stabilizing shaft 431 at one end close to the base 41, and the stabilizing shaft 431 is inserted into the stabilizing hole 411. The stabilizing shaft 431 inserted into the stabilizing hole 411 can stabilize the main sleeve 43.

[0039] A motor 412 is disposed on the right end surface of the base 41 , and the output shaft of the motor 412 is fixedly connected to the stabilizing shaft 431 . The motor 412 can drive the sleeve 43 to rotate slowly.

[0040] The left end surface of the sleeve 43 is provided with an inwardly recessed installation chamber 432, and a plurality of clamping blocks 433 are arranged in the installation chamber 432. This design can clamp and fix the forging.

[0041] The outer wall of the sleeve 43 is provided with a plurality of electric cylinders 434 , and the output shafts of the electric cylinders 434 extend into the interior of the installation bin 432 and are fixedly connected to the clamping block 433 .

[0042] The specific operation mode of the utility model is as follows: when processing the slewing bearing ring forging (hereinafter referred to as the forging), firstly, the equipment is powered on, and then the slewing bearing ring forging is inserted into the installation bin 432 of the sleeve 43, and the electric cylinder 434 is started. The four electric cylinders 434 push the clamping block 433 in the same direction to fix the forging. After fixing, the rotating disk 32 is rotated to rotate the screw rod 31. The rotating screw rod 31 cooperates with the threaded hole of the sliding seat 42 to move the sliding seat 42 (that is, the base 41 moves). When the forging moves to the bottom of the laser cutting head 251 and is aligned with it in the vertical direction, after alignment, the rotating disk 32 is continued to be rotated to make the forging extend to the required size.

[0043] At this time, the servo motor 22 is started, and the servo motor 22 drives the screw rod 23 to rotate. The screw rod 23 engages with the screw hole 241 of the telescopic rod 24, so that the telescopic rod 24 moves downward (that is, the cutting host 25 and the laser cutting head 251 move downward). When the laser cutting head 251 is not far above the forging, the servo motor 22 can be stopped. At this time, the laser cutting head 251 can be started to cut the forging. As the cutting proceeds, the motor 412 will also be started synchronously to drive the stabilizing shaft 431 to rotate, so that the sleeve 43 rotates, which can drive the forging to rotate. As the forging rotates, the laser cutting head 251 can cut it off. After cutting a section, continue to push the forging that has not been cut forward, and extend it to the same size to continue processing. When the entire forging is cut and processed, the servo motor 22 is reversed to reset the cutting host 25 and the laser cutting head 251, and the work is completed.
