Description

technical field [0001] The invention relates to the technical field of pump joint processing, in particular to a double-sided integrated processing jig for a pump joint and a processing method thereof. Background technique [0002] The pump joint is a ball-column splicing overall structure, one end is a sphere and the other end is a cylindrical connecting rod. The characteristics of this device make it possible to change the angle of the pipe connection, so that it is convenient for the pipe connection that needs to change the angle. This joint is often used in the pipe connection of the dynamic device. [0003] The piston oil injection joint of the engine needs to use the pump joint, which is a common device for pipeline connection. For the engine oil circuit, if the joint leaks, it will cause great danger. Therefore, the manufacturing accuracy of the pump joint used in the engine and other high-reliability connection requirements is very high. In order to ensure the high...

Problems solved by technology

[0004] At present, in the processing of pump joints, the sphere is usually clamped with a general fixture, and then the surface exposed outside the fixture is cut, and then the sphere is drilled with a drill bit, and then the sphere is arced inside the hole with a smaller turning tool. Next, remove the pump connector and replace one side for clamping, expose the unprocessed side of the sphere to the outside of the fixture for clamping, and reprocess this side. Such operations need to be carried out on different equipment with different fixtures Repeated clamping is not only cumbersome to operate, but also cannot guarantee the parallelism of the two end faces of the sphere, nor can it guarantee the positional relationship between the connecting rod and the hole in the sphere, so the accuracy cannot be guaranteed

In addition, the current method of opening the inner hole of the sphere is to drill through a drill, which is difficult to control the axis position of the sphere. Reaming and reaming after drilling with the drill bit can only improve the dimensional accuracy but not the position accuracy of the hole. It can ensure the dimensional accuracy of the hole and improve the position accuracy of the hole, which can reach the pump joint standard of the oil circuit of the automobile engine

In short, the operation of the traditional processing method is complicated, the accuracy control is difficult, and the pass rate and efficiency are not high.
