Drilling device with protecting function

Abstract

The invention discloses a drilling device with a protecting function. The drilling device with the protecting function comprises a bottom plate, a left vertical plate is vertically and fixedly installed on the bottom plate, limiting springs are vertically and fixedly installed on the lower bottom face of a top plate, an L-shaped support is fixedly installed at the lower ends of the limiting springs, and a positioning arc groove is formed in the right side wall of the L-shaped support. A sliding rod is vertically arranged on the L-shaped support in a penetrating mode, a driving bevel gear is coaxially and fixedly installed on a first gear, a limiting shaft sleeve is fixedly installed on the left side of a right vertical plate, and a rotating shaft is rotationally arranged in the limiting shaft sleeve in a penetrating mode. According to the drilling device with the protecting function, a drill bit is driven to rotate through the rotating shaft, a clamp clamps a workpiece and moves downwards, and the drilling action to the workpiece is achieved; after the drill bit finishes drilling the workpiece, a position roller is clamped in the positioning arc groove, a sliding seat drives a second gear to move leftwards, the second gear breaks away from a first gear, the drill bit stops rotating, the protecting function is well achieved, safety accidents can be effectively prevented, and meanwhile the drilling quality of the workpiece is guaranteed.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a drilling device with a protective function. Background technique [0002] Machining refers to the process of changing the shape or performance of a workpiece through a mechanical device. Mechanical processing can be divided into cutting processing and pressure processing according to the difference in processing methods. Thermal processing commonly includes heat treatment, forging, casting and welding. With the rapid development of modern mechanical processing and the rapid development of mechanical processing technology, many advanced mechanical processing technology methods have gradually emerged, such as micro-machining technology, rapid prototyping technology, precision ultra-precision processing technology, etc. [0003] When processing a mechanical workpiece, it is often necessary to drill the workpiece and open a reserved installation hole for assembly.

Problems solved by technology

[0003] When processing a mechanical workpiece, it is often necessary to drill the workpiece and open a reserved installation hole for assembly. The current drilling device usually needs to be braked manually after the drilling is completed, but it is often due to the operation of the operator. If you forget to turn off the power to stop the operation by mistake, it is easy to cause the drill to rotate continuously in the workpiece, which is not only prone to safety accidents, but also causes a decrease in drilling quality
