Abstract

Technical Field
[0001] The utility model belongs to the technical field of precision metal processing and relates to a piston drilling detection and positioning processing tooling applied to a door closer piston. Background Art
[0002] The door closer piston is a component of the door closer. The difficulty lies in the fact that there are many holes in the component, various concentric holes, eccentric holes, and superposition of center holes and eccentric holes. During assembly, it must be ensured that all these holes are good, otherwise it will cause trouble for subsequent assembly. The processing of the concentric holes is the initial processing position. If the position of the concentric holes is inaccurate, the subsequent processing is meaningless, and continuing the processing will waste production costs. Therefore, it is particularly important to detect the initial position concentric holes. Considering reducing production costs and improving work efficiency, it is urgent to develop a processing tooling that can simultaneously detect concentric holes and position workpieces.
