[0040] The rolling groove assembly is provided with two, and is arranged on the corresponding turnover table assembly respectively, the rolling groove assembly comprises a motor two 401 and a rotating shaft 402, the motor two 401 is arranged on the top of the mounting table 302, a belt wheel two 407 is arranged on the driving shaft of the motor two 401, the rotating shaft 402 is rotatably arranged on the front side of the mounting table 302, a belt wheel one 405 is arranged on one end of the rotating shaft 402, the belt wheel one 405 and the belt wheel two 407 are connected through a transmission belt 406, a roller 403 is arranged on the other end of the rotating shaft 402, and abrasive flanges 404 are arranged on the circumferential side wall of the roller 403; after the damper inner tube is axially and pressingly limited and stabilized, the belt wheel two 407 is driven to rotate by starting the motor two 401, the rotating shaft 402 is driven to rotate through the transmission belt 406 and the belt wheel one 405, and then the roller 403 is driven to rotate;

[0041] With the continuous recovery of the telescopic end of the electric telescopic rod 303, the mounting table 302 rotates and moves downward around the hinge with the stand 301, which can drive the rollers 403 to move downward, i.e., close to the inner tube of the damper, to realize the rolling groove process. When the mounting table 302 rotates and moves downward, and the bottom of the mounting table 302 presses on the travel switch 306 on the top of the assembled body of the screw cylinder 304 and the screw post 305 with the overall length adjusted, the travel switch 306 can be triggered, i.e., the telescopic end of the electric telescopic rod 303 stops recovering, so that the electric telescopic rod 303 maintains the current telescopic length, and the mounting table 302 is kept stable, so that the rollers 403 stop the downward movement process, i.e., the required rolling groove process amount has been reached. At this time, the abrasive flanges 404 in the rotating rollers 403 have been ground into the wall of the inner tube of the damper. Then, by manually rotating the inner tube of the damper, the abrasive flanges 404 on the two rollers 403 can be ground into the required grooves at both ends of the inner tube of the damper during the rotation of the rollers 403 and the inner tube of the damper, so as to realize the one-time rolling groove processing of the inner tube of the damper at both ends, thereby improving the work efficiency.

[0042] In order to avoid affecting the further rotation and downward movement of the mounting table 302 to drive the rollers 403 to move downward to close to the inner tube of the damper to realize the rolling groove process operation, two clamping grooves 602 are arranged on the assembled frame 601, and a limiting column 603 is vertically arranged in each clamping groove 602.

A pressing wheel 606 is rotatably arranged on one side of each clamping block 604. When the pressing wheel 606 is pressed on the top of the inner tube of the damper, the clamping block 604 can be driven to move upward during the further rotation and downward movement of the mounting table 302, so that the spring 605 is contracted, so that the mounting table 302 can still move downward a certain amount after the pressing wheel 606 is pressed on the top of the inner tube of the damper, thereby not affecting the rolling groove process operation of the rollers 403 moving downward to close to the inner tube of the damper.

[0043] Moreover, the position of the sliding table 103 on the table 101 can be adjusted, so that the position distance between the corresponding components on the sliding table 103 and the same components on the table 101 can be adjusted, thereby being capable of processing dampers with different lengths.
