Description

Technical Field

[0001] The utility model relates to the technical field of production and processing of hydraulic pumps, in particular to a drilling tool for a pump housing. Background Art

[0002] The hydraulic pump housing includes left and right housings and an intermediate housing. During the production process of the hydraulic pump intermediate housing, a large number of holes need to be processed on the front and back sides. When processing the holes, tooling is required to fix the hydraulic pump housing to avoid dislocation due to unstable clamping, which will affect the holes drilled in the hydraulic pump housing.

[0003] After searching, it was found that the publication number is CN216097598U, and the name is a drilling tool for the front and back sides of the intermediate housing of a hydraulic pump. The patent with application number: 201720871713.4 has the problem that when processing the hydraulic pump housing, the fixing of it is not stable enough. During processing, it is easy to be dislocated, which affects the hydraulic pump housing. By setting a clamping assembly, by setting a detachable mounting block and a clamping block in the connecting groove in the movable plate, the intermediate housing of the hydraulic pump can be clamped more firmly, avoiding dislocation during drilling processing, which affects the processing of the intermediate housing of the hydraulic pump. However, the application drives the movable plate to move by the forward and reverse screw rod. When the clamping force is too small, it is difficult to stably clamp the pump housing. When the clamping force is too large, the thread teeth of the forward and reverse screw rod are subjected to excessive force, which is very easy to deform and wear, reducing the service life. At the same time, the debris generated during drilling will fall onto the surface of the forward and reverse screw rod, affecting the operation of the forward and reverse screw rod. Frequent cleaning is also very troublesome, and further improvements can be made.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
