The invention discloses trepanning equipment for building materials. The trepanning equipment comprises an abutting-pressing top plate and a shell; a lifting adjusting plate and a driving motor are arranged in the shell; a through hole is formed in the middle of the bottom wall of the shell; a trepanning drill bit is arranged on a main shaft of the driving motor; an annular through groove which is concentrically arranged with the through hole is formed in the bottom wall of the shell; at least four convex columns are arranged on the bottom surface of the abutting-pressing top plate; an annular positioning abutting block is arranged in the annular through groove; four cylinders are uniformly arranged on the top surface of the annular positioning abutting block; the four convex columns are inserted into the four cylinders respectively; an inclined guide plate is fixedly arranged at the outer side end of the annular positioning abutting block; and a lifting air cylinder is fixed between the top surface of the lifting adjusting plate and the bottom surface of the abutting-pressing top plate. The trepanning equipment has the advantages that the structure set is reasonable, and the drill bit can be effectively prevented from shifting in the drilling process, and therefore the use stability and the drilling precision can be greatly improved, the technical defects that a trepanning tool is prone to eccentricity or displacement in a traditional technology can be overcome, the using stability is good, and the applicability is high.
Description
technical field [0001] The invention belongs to the technical field of building equipment, and in particular relates to a hole opening equipment 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. Contents of the invention [0003] The purpose of the present invention is to provide a drilling device for building materials with reasonable structure and good...
