The crimping connector 105 is snapped and fixed to the upper end of the solenoid valve solenoid tube 304. The inner side wall of the lower end of the riveting head 103 is provided with a pressing slope. The pressing slope gradually narrows from bottom to top. During the downward movement of the pressing slope, the pressing slope presses and narrows the solenoid valve cover 303.
[0024] The press machine is model BGO106-01. The solenoid valve seat 302 is located on the side of the shock absorber 301, and the solenoid valve cover 303 is located on the solenoid valve seat 302.

Through the first protective pad 209, the top of the mounting frame 400 can be prevented from being pressed; through the second protective pad 210, the rotating support block 203 can be prevented from being pressed. In addition, through the first protective pad 209 and the second protective pad 210, the surface of the force receiving place of the electromagnetic valve gland 303 can also be prevented from being pressed.
[0029] After the worker installs the mounting frame 400 on the machining table of the press machine and installs the press rivet head 100 on the lifting structure of the press machine, the pin shaft 211 and the rotating support block 203 can be moved upward, so that the clamping plate 206 is separated from the clamping hole 207, and then the rotating support block 203 is adjusted in rotation, so that the rotating support block 203 is separated from the top of the mounting frame 400.
[0030] Subsequently, after the soft pad and the snap spring are installed on the side of the solenoid coil 304, the solenoid coil 304 is placed into the solenoid cover 303, and then the solenoid base 302 is moved through the access hole 202 into the first mounting clamping hole 201, and then the rotating support block 203 is adjusted to rotate again, so that the rotating support block 203 first touches the top of the mounting frame 400, and then the rotating support block 203 is moved downward, so that the clamping plate 206 is moved downward and clamped and fixed with the clamping hole 207, so that the solenoid base 302 is clamped and fixed by the first mounting clamping hole 201 and the second mounting clamping hole 204, and the boss 305 is supported by the top of the mounting frame 400 and the top of the rotating support block 203, so as to realize the vertical support and fixation of the shock absorber 301.

[0032] Then, the pin shaft 211 and the rotating support block 203 are moved upward again, and the rotating support block 203 is separated from the top of the mounting frame 400, so that the riveted shock absorber 301 can be taken off from the tooling, and the feeding and discharging of the shock absorber 301 can be quickly and conveniently realized, and the overall processing efficiency is improved.
