Technical Field

[0001] The utility model belongs to the technical field of valves, in particular to a ball valve assembly workbench. Background Art

[0002] A ball valve is a valve whose opening and closing parts are spherical. This is the most obvious feature. It is a valve whose opening and closing parts are driven by the valve stem and rotate around the axis of the ball valve.

[0003] The valve is not produced at one time, but is assembled by the staff from various parts such as the internal valve body, valve seat, valve cover, valve core, valve stem, etc. During the assembly, the valve body needs to be fixed;

[0004] Among them, it was discovered during production that the existing assembly device, when fixing the valve body, uses a clamping mold to limit the valve neck of the valve body. When other valve bodies need to be assembled, the clamping mold needs to be replaced, which causes the problem of low efficiency of the device. The flange hole of the valve body itself has a supporting effect. Therefore, a device that can directly position the flange hole is designed to meet the assembly needs of valves of multiple specifications. Utility Model Content

The anti-slip ear 304 is provided in a sheet shape. The valve body is placed on the workbench 2, and the flange hole of the valve body is inserted into the cylinder 301. At this time, the flange hole is pressed down, causing the anti-slip ear 304 to shrink and then open, thereby achieving the purpose of anti-slip. Then, the staff uses an air pump to control the piston rod 302 to move downward. At this time, the anti-slip head 303 and the anti-slip ear 304 move synchronously to anchor the flange hole, thereby achieving the purpose of fixing the valve body.

[0032] When the valve body is removed, the piston rod 302 can be directly extended, and the staff can pinch the anti-disengagement ear 304 by hand to separate the flange hole from the cylinder 301.

[0041] Working principle: First, place the valve body on the workbench 2. When the position of the cylinder 301 needs to be adjusted according to the vacant space of the flange hole, the rack 3011 drives the rotating gear 4 to rotate while pushing the cylinder 301 to move. At this time, the rotating gear 4 engages with another rack 3011 and moves in the opposite direction to adjust the position of the cylinder 301. Then, insert the flange hole of the valve body into the cylinder 301. At this time, the flange hole is pressed down, causing the anti-slip ear 304 to shrink and then open, thereby achieving the purpose of anti-slip. Then, the staff uses an air pump to The piston rod 302 is controlled to move downward. At this time, the anti-slip head 303 and the anti-slip ear 304 move synchronously to anchor the flange hole, thereby fixing the valve body. When the valve body is removed, the piston rod 302 can be directly extended, and the staff can pinch the anti-slip ear 304 by hand to disengage the flange hole from the cylinder 301. Then, by controlling the first electric support rod 101 to extend, the workbench 2 can be rotated around the bearing column 102, thereby changing the angle of the workbench 2, thereby driving the valve body to rotate to meet the assembly needs of the staff.
