[0002] Ball valves are valves whose opening and closing parts are driven by the valve stem and rotate around the axis of the ball valve. They can also be used for fluid regulation and control. The hard-sealed V-type ball valve has a strong shear force between its V-type ball core and the metal valve seat welded with cemented carbide, which is particularly suitable for media containing fibers, tiny solid particles, etc.

[0003] At present, ball valves are assembled manually by workers. Even if there are assembly equipment, the degree of automation of the equipment is low, the assembly efficiency is low, and when the ball valve is clamped, the angle needs to be changed manually by workers, which affects the continuous processing of the ball valve.

Since the two clamping frames are engaged with the outside of the main valve body, the two clamping plates and the clamping frame drive the main valve body to rotate through the bearings to adjust the direction of the ball valve, and the first motor can be controlled to drive the rotating plate at the output end to rotate, thereby driving the fixed plate, the movable plate and the main valve body to rotate, and adjusting the angle of the valve body, so as to facilitate better assembly of the valve body at different angles and directions.

[0017] Second, the present invention sets a material box, a discharge chute, a partition plate, a push plate and a second hydraulic push rod, adjusts the position of the partition plate in advance, adjusts the height of the adjustment plate in the discharge chute, and adjusts the position of the push plate.

At this time, the third motor 1002 is controlled to run. The internal technology of the third motor 1002 is the existing technology. After the third motor 1002 runs, it drives the output end screw rod 1003 to rotate. When the screw rod 1003 rotates, it drives the support frame 1005 and the moving block through the threaded sleeve 1004. 1006 moves to one side, so that the two support rods 1008 inside the moving block 1006 move to the two sides of the valve body flange. At this time, the two cylinders 1007 inside the moving block 1006 are controlled to operate. After the cylinder 1007 operates, it drives the output end support rod 1008 to move inward. When the support rod 1008 moves inward, the clamping sleeve 1009 inside it clamps to the outside of the two flanges. After the two flanges are clamped and limited by the clamping sleeves 1009 on both sides, they are passively aligned, so that the main valve body and the auxiliary valve body are aligned. After alignment, the mechanical arm 12 is screwed to grab the bolts and nuts to fix the two flanges, so that the main valve body and the auxiliary valve body are fixedly connected.
