Description

A cylinder support tooling

technical field

The invention relates to a cylinder supporting tool.

Background technique

The busbar barrels of fully filled and closed combined electrical appliances need to undergo a withstand voltage test before leaving the factory. As shown in Figure 1, the withstand voltage test equipment includes a high voltage generator 100, and one side of the high voltage generator 100 is connected with a joint whose axis extends in the horizontal direction 200 , the joint 200 is coaxially threaded with wires, and the end of the joint 200 is provided with a butt flange 300 . During the test, the bus barrel is set horizontally, one end of the bus barrel is fixedly connected to the joint through the flange, and the other end is supported by the support tool 500. After the bus barrel is connected to the withstand voltage test equipment, the wires inside the bus barrel 400 are connected to the wires in the joint, and the high voltage generated by the high voltage generator 100 is transmitted to the bus barrel 400 through the joint 200, and the withstand voltage test can be performed.

The existing support tooling includes a bracket and a V-shaped block fixed on the top of the bracket. When in use, the busbar barrel is horizontally placed in the V-shaped groove of the V-shaped block. Since the center height of the joints of the pressure test equipment is fixed, and the specifications of the busbar barrels to be tested are different, and the diameters are different, in order to meet the center height of the busbar barrels with different diameters, they can be kept consistent with the center height of the joints of the pressure test equipment To realize the connection between the busbar tube and the pressure test equipment, different diameters of the busbar tube are required to correspond to different support heights. Since the included angle of the V-groove of a V-shaped block is certain, if the diameter of the busbar barrel to be supported is large, after the busbar barrel is placed on the V-shaped block, the supporting angle of the V-shaped block cannot be equal to the diameter of the busbar barrel. Adaptation will cause the problem of unstable support; in addition, the increase of the diameter of the busbar barrel is accompanied by the rise of the center, which requires reducing the support height of the support tooling. Due to the unstable support of the support tooling, it is easy to cause the busbar The barrel falls and causes damage to the external structure of the busbar barrel. When the diameter of the bus barrel is small, although the V-shaped block can stably support the bus barrel, there is a mismatch between the V-shaped block and the diameter of the bus barrel, which causes the center height of the bus barrel to be low. In order to match the diameter of the V-shaped block and the busbar barrel, usually the same V-shaped block can only support one or two different specifications of the busbar barrel. A support tool that can match busbar barrels of various diameters is required.
