[0031] Specifically, after the jig 3 drives the first connecting member 101 and the second connecting member 102 to move between the spinning component 1 and the lifting component 2, the lifting drive assembly 21 drives the support column 22 to support the bottom of the first connecting member 101, and the spinning drive 11 drives the pressure head 12 to rotate and move downward until the pressure head 12 rivets the upper end of the first connecting member 101 onto the second connecting member 102. In the present utility model, the spinning mechanism can spin the first connecting member 101 onto the second connecting member 102, ensuring the stability of the connection between the first connecting member 101 and the second connecting member 102, and in the process of the spinning component 1 spinning the first connecting member 101, the lifting component 2 supports the bottom of the first connecting member 101, avoiding the accident of the first connecting member 101 loosening during the spinning process, further proving the stability of the connection between the first connecting member 101 and the second connecting member 102.

[0032] In one embodiment, if Figure 2 As shown, the lifting drive assembly 21 includes a mobile drive member 211, a roller 212, a guide block 213, a support frame 214 and a top block 215 slidably mounted on the support frame 214; the support column 22 is mounted on the top block 215; it can be understood that the top block 215 is slidably mounted on the support frame 214 along the up and down directions, and the mobile drive member 211 includes but is not limited to a linear motor, a pneumatic cylinder, a hydraulic cylinder and a screw nut mechanism.

[0033] The guide block 213 is provided with a guide bevel 2131, and the roller 212 is rotatably mounted on the top block 215 and rollingly mounted in the guide bevel 2131; it can be understood that the guide bevel 2131 includes a first guide groove, a second guide groove and a bevel connected between the first guide groove and the second guide groove, and the height of the first guide groove is greater than the height of the second guide groove.

[0035] Specifically, the movable drive member 211 drives the guide block 213 to move horizontally, and the roller 212 rolls in the guide chute 2131 of the guide block 213, thereby driving the guide block 213 to move up and down on the support frame 214. The top block 215 then drives the support column 22 thereon to support the bottom of the first connecting member 101. In this embodiment, the lifting drive assembly 21 has a compact structure, occupies a small space, and has a large lifting force; the lifting drive assembly can also withstand a large riveting pressure.

[0036] In one embodiment, if Figure 2 As shown, the fixture 3 is further provided with a positioning hole 32 , and the lifting component 2 further includes a positioning member 25 installed on the top block 215 ; the positioning member 25 is inserted into the positioning hole 32 for positioning the fixture 3 .

[0037] Specifically, the mobile driving member 211 drives the guide block 213 to move horizontally, and the roller 212 rolls in the guide inclined groove 2131 of the guide block 213, so that the guide block 213 can drive the top block 215 to move up and down on the support frame 214, and then the top block 215 drives the positioning member 25 thereon to be inserted into the positioning hole 32, and the top block 215 can drive the support column 22 thereon to support the bottom of the first connecting member 101, so that the lifting component 2 has the function of bearing the riveting pressure while also having the positioning function, further ensuring the riveting accuracy and riveting stability of the spinning mechanism.

The second connecting member 102 is mounted in the mounting slot 31, and the bottom of the first connecting member 101 extends through the through-hole. It is understood that the upper end of the first connecting member 101 extends above the jig 3, and the lower end of the first connecting member 101 extends through the through-hole, so that the pressing head 12 can press and rivet the upper end of the first connecting member 101, and the support column 22 can support the lower end of the first connecting member 101.

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
