[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This hydraulic cylinder bore boring and rolling composite machining tool, through the setting of the snap-fit ​​assembly, allows the operator to press the slide rod inward according to the needs of the application scenario. The spring extends outward, and the extension plate moves accordingly with the movement of the slide rod and the spring, causing the snap-fit ​​block to extend backward inside the snap-fit ​​groove. Then, the limiting post is inserted into the mounting frame. When the limiting post moves to the appropriate position, the slide rod is released, and the spring drives the extension plate and the snap-fit ​​block to rebound, causing the snap-fit ​​block and the snap-fit ​​groove to engage. During disassembly, the operator only needs to press the slide rod, which drives the spring, the extension plate, and the snap-fit ​​block to move backward, causing the snap-fit ​​block and the snap-fit ​​groove to separate. Then, the limiting post can be pulled out, thus achieving quick installation and disassembly and improving convenience.

[0016] 2. This hydraulic cylinder bore boring and rolling composite machining tool utilizes a rotating chip removal assembly, a hob, and a boring tool. In use, an external power source is first connected, and a servo motor is started. The servo motor drives the transmission rod and the spiral chip removal rod to rotate. The rotation of the spiral chip removal rod causes the hob and boring tool to rotate and work on the hydraulic cylinder bore. During operation, the hob and boring tool generate chips. The rotation of the spiral chip removal rod quickly removes these chips from inside the hydraulic cylinder, thus preventing chip accumulation and ensuring proper machining.
