[0035] Usage process:

[0036] 1. External centering end pressing: First, place the to-be-machined ring gear part 4 on the disk body 30 of the centering end pressing tray 3; then, the external alignment end pressing tray unit 2 works. The slewing bearing 213 on the fixed base 20 rotates, and the servo motor 22 on the slewing base 21 drives the lead screw 27 to rotate through the speed reducer 23, causing the first quick-connect integrated board 28 to move. During this process, the position of the ring gear is detected by the laser distance sensor 214. After calculating the deviation value, control the two groups of servo motors 22 to move in the X and Y directions to make the center of the ring gear part 4 coincide with the reference center, achieving automatic alignment and centering; after the workpiece centering adjustment is completed, start the disc spring pressing swing cylinder 37 to press the end face of the ring gear. After pressing, the hydraulic oil circuit of the disc spring locking cylinder 33 is disconnected to mechanically lock the clamping sleeve and complete the end pressing and fixing;

[0037] 2. Hoisting and connection: Lift the ring gear part 4 and the centering end pressing tray 3 that have completed centering end pressing by the workshop overhead crane and hoist them onto the machine tool. The centering end pressing tray 3 and the internal tray of the machine are powered by a handheld small pump station, and the quick-connect pipeline joint is used to release the lock, quickly connecting and positioning the centering end pressing tray 3 and the internal tray of the machine;

[0038] 3. Machining: After the connection is completed, the machine tool starts to machine the ring gear part 4. During the machining process, all the clamping mechanisms of the internal tray of the machine are in the final mechanical locking state to ensure reliable machining;

[0039] 4. Removal and replacement: After machining is completed, remove the centering end pressing tray 3 with the machined ring gear from the internal tray of the machine, place it on the external alignment end pressing tray unit 2 by the workshop overhead crane, and remove the machined ring gear from the centering end pressing tray 3.

[0040] Finally, repeat the above steps, put in a new to-be-machined ring gear part 4, and start the next round of machining.
