AI Technical Summary

Technical Problem

Existing automotive pipe drilling and positioning mechanisms are complex in structure, inconvenient to fix, affecting work efficiency, and the drill bits are difficult to maintain, resulting in a shortened service life.

Method used

A positioning mechanism including a collection trough, a limiting plate, and a cleaning component was designed. The fixing process is simplified by using the arc to match the fixing pipe, and the cleaning component removes dirt and dust from the drill bit. The drying device is used to maintain the drill bit and prevent damage from external collisions.

Benefits of technology

It enables rapid fixing of pipe fittings, improves drilling efficiency, extends the service life of drill bits, and avoids damage caused by complex fixing and external collisions.

Abstract

The utility model belongs to the technical field of punching and positioning of automobile pipe fittings, and particularly relates to a positioning mechanism for punching of automobile pipe fittings, which comprises a workbench and further comprises a collecting tank movably mounted on one side of the top of the workbench, a fixing block fixedly mounted between the collecting tank, a limiting plate movably mounted on the top of the fixing block, and a positioning plate movably mounted on the limiting plate. Through holes are formed in one ends of the limiting plates in a penetrating mode, fixing bolts are movably installed on the tops of the limiting plates, the fixing blocks can be fixed through the collecting grooves, the fixing blocks are provided with radians and can be matched with the radians of the pipe fittings, the pipe fittings are placed, the limiting plates are placed in the collecting grooves, then the limiting plates are pushed, and the fixing bolts are movably installed on the tops of the limiting plates. The pipe fittings can be clamped in the collecting groove, then the limiting plate is fixed into the through hole through the fixing bolt, the limiting plate can be fixed, the pipe fittings of different lengths and sizes can be clamped, the pipe fittings are used in cooperation, a pipe fitting fixing mechanism is convenient enough, and complex fixing is not needed before punching.
