The lower connecting plate press-fitting and holding assembly is a device or apparatus specially used in the lower connecting plate press-fitting process. Its main function is to ensure the stability, accuracy and efficiency of the lower connecting plate during the press-fitting process.

[0003] The lower connecting plate press-fitting and holding assembly usually includes a frame, a workbench, a supporting device, a pressing head, a piston rod and other parts. During the press-fitting process, the supporting device fixes the lower connecting plate on the workbench, and the pressing head is driven up and down by the piston rod to apply pressure to the lower connecting plate to achieve the press-fitting operation.

[0004] Among them, after searching, it was found that the patent application number CN201520447753.7 discloses a press-fitting processing device for a lower connecting plate assembly. It includes a frame, a workbench is arranged at the lower part of the frame, and a supporting device for supporting the lower connecting plate is arranged on the workbench; a pressing head corresponding to the lower connecting plate is arranged at the upper part of the frame, and the pressing head is driven by a piston rod to move up and down; a sensing block is arranged on the piston rod, and a proximity switch corresponding to the sensing block is arranged on the frame;

[0005] When this structure is in use, a proximity switch is installed on the frame, and its sensing block is installed on the piston rod. When in use, the sensing block is adjusted to a position where the pressure required to be measured during the pressing process of the lower connecting plate is detected by the proximity switch. However, this structure is not easy to position the workpiece when in use, causing the workpiece to easily shift during press-fitting, making it difficult to ensure the press-fitting accuracy.
