Drilling depth positioning device for machining

Abstract

The invention provides a drilling depth positioning device for machining, and relates to the technical field of drilling depth positioning devices.The drilling depth positioning device comprises a drilling positioning assembly, a positioning shell is inserted into a supporting shell, when the drilling depth positioning device is used, the drilling positioning assembly can limit and adjust the maximum drilling depth of a drill bit assembly, and the maximum drilling depth of the drill bit assembly can be adjusted; according to the drilling device, positioning is more accurate during drilling, the drilling device can adapt to the operation of drilling a workpiece at different depths, and a drill bit of a drill bit assembly of the drilling device is hidden in a supporting shell in a reset state, so that the phenomenon that the drill bit is broken due to external bumping and collision when not used can be avoided; the problems that an existing drilling device is not provided with a drilling depth positioning device, multiple times of repeated measurement and drilling are needed for drilling a hole with the needed depth, the steps are tedious and quite troublesome, and a drill bit is exposed out of the device and is prone to being broken due to external collision and collision are solved.

Description

technical field [0001] The invention relates to the technical field of drilling depth positioning device, in particular to a drilling depth positioning device for machining. Background technology [0002] Drilling is one of the most common processing operations in machining. Drilling refers to the operation of machining holes on solid materials with a drill bit. In machining, the drill bit is driven to rotate by a motor to drill the surface of the workpiece, so as to complete the subsequent processing and assembly of the workpiece through the drilled holes. [0003] However, as far as the current drilling device is concerned, it does not have a drilling depth positioning device. When drilling, it is completely based on the experience of workers, and the holes drilled to the required depth need to be measured and drilled repeatedly. The steps are cumbersome and cumbersome. In addition, the drill bits of the existing drilling device are generally leaked outside the device, and ther...

[0003] However, as far as the current drilling device is concerned, it does not have a drilling depth positioning device. When drilling, it is completely dependent on the experience of the worker to drill the hole, and the hole of the required depth needs to be repeatedly measured and drilled, and the steps are cumbersome. It is very troublesome, and the drill bit of the existing drilling device generally leaks outside the device, and there is no buffer device when drilling, and it is easy to cause the drill bit to break and become unusable due to external bumps, collisions and constant downforce in the drilling hole Occurs, virtually increases the cost of use, poor practicability
