Automatic assist device capable of precisely blocking and preventing inner hole deformation and used for woodworking drilling machine

Abstract

The invention discloses an automatic assist device capable of precisely blocking and preventing inner hole deformation and used for a woodworking drilling machine. The automatic assist device is structurally characterized by comprising a precise blocking device, a knob button, a baffle plate, a limiting pin, a hand-pushing plate and a fixed plate. The automatic assist device has the beneficial effects that: a partition plate is utilized to protect a drill bit while a protective assembly is in contact with a drill bit of the drilling machine, so that blowing effect on wood bits stayed in holesis achieved during drilling by moving gas flow, and a phenomenon that holes are inconsistent in size due to the fact that the stayed wood bits expand the hole diameters of the holes and change the hole depth is avoided. A fixed buckle structure is mutually matched with a friction strip, so that linear drilling of the holes is achieved during drilling, hole twisting due to equipment vibration is avoided while a woodworker drills is avoided; and moreover, the wood worker needs to position and change continuously to cause inaccurate hole lines to affect later-stage buckling.

Description

technical field [0001] The invention relates to the technical field of drilling machine positioning, more precisely, it relates to an automatic auxiliary device for woodworking drilling machinery that precisely locks the position and prevents deformation of the inner hole. Background technique [0002] With people's pursuit and upsurge of logs in home decoration, more and more people prefer to use wood panels for house interior decoration. Therefore, under the influence of different needs for wood decoration, carpenters need to carry out suitable adjustments for solid wood panels. Processing, when drilling wood panels with a drilling machine, due to the vibration generated by the drilling machine during operation, the drilled holes are distorted, requiring continuous positioning changes by the woodworker, resulting in hole lines It is not accurate enough, which will affect the fastening of parts in the later stage. At the same time, when drilling, there will be a large amoun...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the deficiencies in the prior art, the object of the present invention is to provide an automatic auxiliary device for woodworking drilling machinery that is precise in position and prevents deformation of the inner hole, so as to solve the vibration generated by the drilling machinery in the prior art during operation. As a result, the drilled holes are distorted, requiring the carpenter to constantly change the positioning, resulting in inaccurate hole lines, affecting the fastening of the later parts. At the same time, there will be a large amount of wood chips staying inside the hole when drilling , causing the staying wood chips to expand the diameter of the hole and change the depth of the hole, resulting in the defect that the drilled holes are of different sizes
