When the photoelectric switch 711 on the induction base 71 facing the lower die sleeve 421 detects whether a work station 423 is blocked or not, and when the blocking is not detected, the controller 73 controls the divider 41 to drive the turntable 42 to rotate 90 degrees anticlockwise, so that the lower die sleeve 421 after the feeding is completed rotates to two work stations 424, when the photoelectric switch 711 on the induction base 71 detects that the lower die sleeve 421 at the two work stations 424 is blocked by a valve body, the controller 73 controls the lifting cylinder one 25 to push the bearing seat one 251 to move downwards, so that the spline sleeve one 23 and the upper die sleeve one 24 synchronously move downwards, the upper die sleeve one 24 contacts with a valve cap on the lower die sleeve 421, the return spring one 243 buffers and protects the upper die sleeve one 24, and after the correlation switch 72 detects that a flashboard is arranged in the valve body through a flow passage of the valve body, the controller 73 controls the rotating motor one 21 to rotate reversely, so that the valve rod is in threaded connection with the gate valve, the gate valve is lifted, and the correlation, the controller 73 controls the first rotating motor 21 to rotate forwards, so that the valve cover is in threaded connection with the valve body, the first rotating motor stops rotating after the valve cover is connected with the valve body, the first upper die sleeve 24 moves upwards under the control of the first lifting cylinder 25, and the first rotary assembly mechanism 2 finishes working.

The divider 41 controls the turntable 42 to rotate 90 degrees counterclockwise, so that the lower die sleeve 421 drives the assembled valve rod, gate, valve cover and valve body to rotate to the three-station 425, when the photoelectric switch 711 on the induction base 71 detects that the lower die sleeve 421 at the three-station 425 is shielded by the valve body, the controller 73 controls the lifting cylinder two 35 to push the spline sleeve two 33 and the upper die sleeve two 34 to move downward, the upper die sleeve two 34 moves downward to the valve body to be assembled on the lower die sleeve 421 and is nested with the press cap, the rotating motor controls the upper die sleeve two 34 to rotate, so that the press cap is in threaded connection with the valve cover, the rotating motor two 31 stops rotating, the lifting cylinder two 35 drives the upper die sleeve two 34 to move upward, and the assembly mechanism two 3 finishes working.

The divider 41 controls the turntable 42 to rotate 90 degrees counterclockwise, so that the lower die sleeve 421 drives the assembled valve body to rotate to the four-station 426, after the photoelectric switch 711 on the induction base 71 detects the valve body on the four-station 426, the controller 73 controls the lifting cylinder three 51 to drive the rotary cylinder 52 to move downward, meanwhile, the clamping jaw cylinder 54 controls the clamping jaw 541 to separate, after the output end of the lifting cylinder descends to the lowest point, the controller 73 controls the clamping jaw cylinder 54 to work, so that the clamping jaw 541 closes, at the moment, the clamping jaw 541 clamps the lower end of the press cap and controls the clamping jaw 541 to move upward by the lifting cylinder three 51, after the photoelectric switch 711 on the induction base 71 does not detect the valve body on the three-station 425, the controller 73 receives a signal and controls the marking machine 61 to start marking the valve body on the clamping jaw 541, after the time of the marking machine 61 is over, the marking machine 61 stops working, the rotary cylinder 52, the clamping jaw 541 and the valve body on the clamping jaw 541 are located on the outer side of the machine frame 1, the controller 73 controls the clamping jaw 541 to be separated, blanking is completed, and the assembly process of the valve body is completed; while blanking, the divider 41 controls the turntable 42 to rotate 90 degrees counterclockwise, so that the blanked lower die sleeve 421 rotates back to the first station 423; the lower die sleeve 421 at one station 423 can be loaded without a valve body to be assembled, and the other three stations can work simultaneously.

The controller 73 controls the first lifting motor 111 and the second lifting motor 121 to work, so that the heights of the first assembling mechanism 2 and the second assembling mechanism 3 are adjusted, and the gate valves with different heights are assembled.
