In other embodiments, the number of the feeding mechanism 30 and the pressing mechanism 40 can be specifically set, which will not be described in detail here.

[0048] Furthermore, if Figure 5As shown, the jacking mechanism 10 includes a jacking driving member 12 and a jacking seat 13. The fixed end of the jacking driving member 12 is installed on the frame, and the jacking seat 13 is drivingly connected to the output end of the jacking driving member 12. The jacking driving member 12 is used to drive the jacking seat 13 to move up and down, and the jacking seat 13 is used to support the cylinder block assembly 2. Specifically, in this embodiment, the jacking mechanism 10 further includes a fixing plate 11. The fixing plate 11 is installed on the top of the third frame 16. The jacking driving member 12 is an oil cylinder. The output shaft of the oil cylinder is connected to the jacking seat 13, and the cylinder body of the oil cylinder is connected to the fixing plate 11. The jacking seat 13 supports the cylinder block assembly 2.

Specifically, in this embodiment, the tightening driving member 151 is a tightening cylinder. The cylinder body of the tightening cylinder is fixedly connected to the fixing plate 11. The output shaft of the tightening cylinder is connected to the tightening block 152. After the oil cylinder jacks up the jacking seat 13, the tightening cylinder drives the tightening block 152 to tightly abut against the guide shaft 141, which can fix the guide shaft 141, prevent the guide shaft 141 from sliding along the guide hole, thereby ensuring the stability of the jacking seat 13, further enhancing the stability of the cylinder block assembly 2, and facilitating the positioning of the cylinder block assembly 2.

[0053] In this embodiment, one side of the tightening block 152 close to the guide shaft 141 is of an arc structure, which can increase the contact area with the guide shaft 141, thereby increasing the friction force and ensuring the wedging effect of the guide shaft 141. The tightening block 152 is made of rubber, which can also improve the friction force and further enhance the wedging effect to ensure the stability of the guide shaft 141.

[0054] Further, please refer to Figure 3 As shown, the side positioning assembly 21 includes an abutting plate 211 and a side driving member 212.
