Bench drilling machine high in clamping degree and convenient to adjust

Abstract

The invention relates to the technical field of bench drilling machines, and discloses a bench drilling machine high in clamping degree and convenient to adjust. The bench drilling machine comprises abase, wherein supporting legs are fixedly arranged at the bottom of the base. According to the bench drilling machine high in clamping degree and convenient to adjust, the size of a limiting groove is matched with the size of an object to be drilled, so that the limiting groove is used for limiting the object to be drilled for the first time, and then displacement is prevented from being generated in the front-and-back mode; after the object to be drilled is placed, threaded rods are rotated, at the moment, the threaded rods rotate oppositely after first threaded holes and second threaded holes are rotated, and then two clamping blocks are pressed on the front side and the rear side of the object to be drilled; air in suction grooves is squeezed out, so that the interiors of suction grooves are enabled to be in a maintain state, and then the object to be drilled is clamped; the suction grooves with the number of not being smaller than two are formed, so that clamping on the object tobe drilled through the clamping blocks is enabled to be steadier; and moreover, the clamping blocks are arranged as rubber and can be slightly deformed, so that the clamping blocks are more tightly attached to the object to be drilled, and the purpose of high clamping degree is achieved.

Description

technical field [0001] The invention relates to the technical field of bench-top drilling machines, in particular to a bench-top drilling machine with high clamping degree and easy adjustment. Background technique [0002] The bench drill is referred to as a bench drill, which refers to a small drill that can be placed on the workbench and the main shaft is arranged vertically. The position of the belt on the tower pulley is realized. The spindle feed is manually operated. The bench drilling machine is mainly used for drilling, reaming, reaming, tapping and scraping of small and medium-sized parts. It is used in processing workshops and mold repair workshops. Compared with the same type of machine tools at home and abroad, it has the characteristics of small horsepower, high rigidity, high precision, good rigidity, convenient operation and easy maintenance. [0003] For example, Chinese patent CN 104070197B discloses a multifunctional desktop drilling machine, the lower wor...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a desktop drilling machine with high clamping degree and easy adjustment, which has the advantages of high clamping degree and solves the disadvantage of low clamping degree. When processing the object to be drilled, due to The clamping degree of the object to be drilled is not high, and it is easy to make it move, so that the drilled hole is not perpendicular to the object to be drilled, which affects the accuracy of the drilled hole
