Hole opening equipment for building materials

Abstract

The invention discloses tapping equipment for building materials. The tapping equipment comprises a top plate, a pipe body and a bottom plate, the bottom plate is provided with a central through holeand a plurality of strip-shaped through holes, a driving motor with a tapping drill bit is arranged in an inner cavity of the pipe body, a guide column penetrates through a middle supporting plate ofthe driving motor, and the guide column is fixed on the inner wall of the pipe body through a positioning block, the outer side of the guide column is sleeved with a first spring, the lower end of thepositioning block is connected with a first propping block through a second spring, the first propping block is in sliding connection with a second propping block, a driven pressure rod is arranged above the first propping block, the lower end of the first propping block extends to form an anti-deflection block, and a main pressure rod with a handle penetrates through the top plate. The first propping block and the second propping block are reasonable in division of work, the first propping block prevents eccentricity of a drill rod by the anti-deviation block on the first propping block, andthe second propping block makes contact with plates by a pressing foot, so that the anti-skid effect is good; the exhaust heat radiation system is reasonable in design, an extra motor is needed, a main shaft of the driving motor is used for driving a fan blade assembly to rotate, and good heat radiation is realized.

Description

technical field [0001] The invention relates to the technical field of building material processing, in particular to a drilling device for building materials. Background technique [0002] In the construction process, some building materials need to be drilled according to the needs, and the hole diameter required by the building materials will be relatively large. The traditional building drilling device is mainly composed of a motor and a drilling tool. Although it can be used to a certain extent However, due to the high hardness of the building material and the uneven distribution of the seal, it is easy to cause the eccentricity or displacement of the drilling tool during drilling, which will affect the accuracy and accuracy of drilling. efficiency, so the applicability and practicality are limited. [0003] For this reason, in the patent specification that publication number is CN107138771B, disclose a kind of opening device for building material, comprise pressing to...

AI Technical Summary

Problems solved by technology

There are deficiencies in this kind of opening equipment for building materials. The first is that the setting of the ring through groove will cause the through hole in the middle of the bottom wall of the housing to have no supporting matrix, so the ring through groove needs to be improved; the second is the positioning of the ring. There are anti-slip protruding teeth on the bottom of the block, so that when the ring is positioned against the building plate, the surface of the plate will be easily scratched due to its own activities; the third is that the position of the inclined guide plate cannot be adjusted according to the demand; the fourth is the exhaust and heat dissipation The system design is relatively complicated, and an additional motor is required to provide wind power
