AI Technical Summary

Technical Problem

Existing oil pump end cap drilling devices have poor clamping adaptability during processing, especially for disc-shaped end caps with protruding edges, and the drilling operation has low continuity, affecting processing efficiency.

Method used

A drilling device for end cap processing was designed. It adopts clamping components equidistantly arranged on a bearing turntable. The clamping components are moved by a rotation control motor to realize continuous drilling of the end cap. The device is adapted and positioned by the protrusion placement cavity and protrusion limiting accessories in the clamping components to ensure stability.

Benefits of technology

This improves the continuity and efficiency of end cap drilling, avoids the impact of disassembly and clamping operations on processing efficiency, and ensures the stability and adaptability of the drilling process.

Abstract

The application relates to the technical field of drilling devices, in particular to a drilling device for end cover machining. Four sets of clamping assemblies are equidistantly arranged on a bearing turntable to clamp the end cover. When the end cover is drilled by a drilling mechanism, a rotating control motor drives a certain clamping assembly on the bearing turntable to move to a machining position, the drilling of the end cover has good continuity in the process, so as to avoid the influence of dismounting and mounting operations on the drilling efficiency, and the machining efficiency is improved. The clamping assembly arranged in the application can be matched with the end cover for clamping and positioning, in particular, a convex head cavity for placing the convex head body is arranged in the bearing ring body, and the convex head body is clamped and positioned by the arranged convex head limiting accessory, so that the end cover has better clamping and positioning effect, and the stability of drilling is ensured.
