Positioning and punching protection device for automobile hub punching machine tool

Abstract

The invention relates to the technical field of automobile part machining machine tools, and discloses a positioning and punching protection device for an automobile hub punching machine tool. The positioning and punching protection device comprises a shell, wherein a photosensitive component is fixedly connected to the interior of the shell, a supporting plate is fixedly connected to the interiorof the shell, a turntable is movably connected to the exterior of the supporting plate, and a connecting rod is movably connected to the exterior of the turntable. Under the interaction of all the structures of the device, when a wheel hub is machined, the circle center of the wheel hub can be the dead center, in this way, the situation that when an operator fixes the wheel hub, the center of thewheel hub deviates, and consequently the machined wheel hub is unqualified is avoided, machining precision is improved, and the percent of pass of products is guaranteed. A ratchet wheel disc can bedecelerated in time when the rotating speed of the ratchet wheel disc is too high, so that the effect of decelerating the ratchet wheel disc in time when the ratchet wheel disc stalls is achieved, thepersonal safety of an operator is protected, the machining efficiency is improved, and the device conforms to the design concept of intelligent manufacturing.

Description

technical field [0001] The invention relates to the technical field of automobile parts processing machine tools, in particular to a positioning and punching protection device for automobile wheel hub punching machine tools. Background technique [0002] The automobile wheel hub punching device is a device used to punch the wheel hub in the process of automobile production and processing to obtain complete parts of the automobile. It has been widely used in the field of automobile production and processing; but the current punching device It is necessary for the operator to put the wheel hub on the bottom plate, and the operator needs to rotate or move it, so that not only the stability is poor when drilling the wheel hub, but also the operator's operation safety cannot be guaranteed. Although the processing machine tool does not need to fix the wheel hub, it can only punch holes at equal angles and uniformly, and the punching device cannot be adjusted according to different...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a positioning and punching protection device for automobile wheel hub punching machine tools, which can automatically adjust the processing position, automatically fix the wheel hub, and timely align it when the ratchet disc stalls. The advantage of deceleration solves the problems that the processing angle cannot be adjusted, the hub cannot be fixed automatically, and the processing will cause problems when the ratchet disc stalls.
