During the actual use, the first six-axis manipulator 15 moves the valve body assembly on the second turnover table 25 to the vacant fixed tooling 33, then places the valve cover assembly in the first assembling mechanism 1 on the valve body, and the lead screw module 345 drives the first connecting frame 343 and the second connecting frame 344 to the upper part of the valve cover, and then closes the tightening assembly 34 to act: the lead screw module 345 drives the first connecting frame 343 and the second connecting frame 344 to move downwards, so that the second connecting frame 344 abuts against the stop piece 350, a screw hole of the valve cover is aligned with the lower end of the vertical through hole 3572, then a middle cavity bolt is fed into the silicone tube, the middle cavity bolt enters the vertical through hole 3572 after passing through the inclined through hole 3571, then the lead screw module 345 continues to drive the first connecting frame 343 to move downwards relative to the second linear guide rail 133, at the moment, the second connecting frame 344 is fixed and does not move, so that the first linear bearing moves downwards relative to the optical axis 35353 until the lead screw module 345 drives the conversion head 349 to enter the vertical through hole 72 and be clamped with the middle cavity bolt in the vertical through hole 3572, and then the first motor 346 is started to drive the universal joint 347, the transmission shaft 348 and the conversion head 349 to synchronously rotate, so that the middle cavity bolt is screwed. After the product is screwed, the lead screw module 345 drives the first connecting frame 343 to move upwards, the first connecting frame 343 drives the second connecting frame 344 to move upwards through the guide piece, and then the power source drives the rotating table 32 to rotate, so that the fixing tool 33 at another hole position rotates to the position below the folding and screwing assembly 34.

In the design, the first connecting frame 343 and the second connecting frame 344 which can move relatively are arranged, after the silica gel guide pipe 358 enters the middle cavity bolt, the first connecting frame 343 moves downwards to enable the converting head 349 to extend into the connecting block 357 to be clamped with the middle cavity bolt, further screwing of the middle cavity bolt is guaranteed, and the closing efficiency of the valve body assembly and the valve cover assembly is improved.

Specifically, the method comprises the following steps: as shown in fig. 3, the guiding member includes a first linear bearing disposed on the first connecting frame 343, a second linear bearing 352 disposed on the second connecting frame 344 and corresponding to the first linear bearing, an optical axis 353 slidably fitted in the first and second linear bearings 352, a stop 354 disposed at an upper end of the optical axis 353, a fixing block 355 disposed at a lower end of the optical axis 353, and a cushion 356 disposed at an upper end of the fixing block 355,

in actual use, when the valve body assembly and the bonnet assembly are brought together without aligned threaded bores below the tightening assembly 34. The first connecting frame 343 and the second connecting frame 344 need to reserve a space for transferring the manipulator 36, at this time, the cushion pad 356 abuts against the lower end of the second connecting frame 344, and the stop block 354 abuts against the second connecting frame 344, so that the second connecting frame 344 and the first connecting frame 343 are fixed to the rotary table 32 by the screw rod module 345, and the valve body assembly and the valve cover assembly can be moved to a position below the closing and tightening assembly 34. After the valve body assembly and the valve cover assembly move to the position below the closed tightening assembly 34 along with the fixing tool 33, the screw rod module 345 drives the first connecting frame 343 to move downwards, so that the optical axis 353 synchronously moves downwards for a certain distance, and finally the second connecting frame 344 moves to enable the vertical through hole 3572 of the connecting block 357 to be aligned with the screw hole of the valve cover assembly.

In the above design, by arranging the optical axis 353, the stopper 354 and the fixing block 355, the second connecting frame 344 can slide relative to the first connecting frame 343, and meanwhile, the cushion 356 is arranged so that when the first connecting frame 343 moves upwards to drive the second connecting frame 344 to move synchronously, the cushion 356 eliminates the impact between a part of the fixing block 355 and the second connecting frame 344, and the service life of the fixing block 355 and the second connecting frame 344 is prolonged.
