Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a clamp for processing a ball valve. Background Art

[0002] As we all know, ball valves are mainly used to cut off or connect the medium in the pipeline, and can also be used for fluid regulation and control. Among them, the hard-sealed V-type ball valve has a strong shear force between its V-type ball core and the metal valve seat with cladding carbide, which is particularly suitable for media containing fibers, tiny solid particles, etc. Ball valves are mainly used to cut off or connect the medium in the pipeline, and can also be used for fluid regulation and control. Among them, the hard-sealed V-type ball valve has a strong shear force between its V-type ball core and the metal valve seat with cladding carbide, which is particularly suitable for media containing fibers, tiny solid particles, etc. During the processing of the ball valve, it is necessary to clamp it with a fixture, and perform operations such as drilling and tapping the valve cover.

[0003] The patent with publication number CN216881851U proposes a ball valve processing fixture, including a fixture box, a first sliding opening is opened on the left side of the upper end surface of the fixture box, and a first slide plate is slidably connected to the inner wall of the first sliding opening, and a motor is fixedly installed on the left end of the fixture box, and the output end of the motor is fixedly connected to the first threaded rod, and a second sliding opening is provided on the front and rear sides of the upper end surface of the fixture box, and the inner wall of the second sliding opening is slidably connected to the second slide plate, and the second slide plate is threaded with a second threaded rod. When in use, the motor drives the first threaded rod and the second threaded rod to rotate synchronously. When the first threaded rod rotates, it will drive the first slide plate to move to the right side, and the limit plates on the left and right sides will position the two ends of the ball valve body. When the second threaded rod rotates, it will drive the second slide plates on the front and rear sides to move relatively, and the positioning piece will fit between the valve cover and the ball valve body, thereby improving the positioning effect and ensuring the accuracy of the valve cover when punching.

[0004] When the above structure is in use, the tool box lacks a buffer structure, and the valve body is directly placed on the tool box, which is easy to bump into the tool box, thus shortening the service life of the tool box. Utility Model Content
