Edge pressure-controlled perforator

Abstract

The invention provides an edge pressure-controlled perforator, and belongs to the technical field of punching equipment. The edge pressure-controlled perforator comprises a base, a longitudinal beam,a horizontal cross beam and a floating block; the base is horizontally arranged; the longitudinal beam is fixedly connected to one corner part of the plane of the base; a slide block sleeves the longitudinal beam; the horizontal cross beam fixedly connected with the slide block as a whole is arranged on one side of the slide block; the floating block sleeves the horizontal cross beam; a motor fixed flange and a motor ring base are fixedly connected through bolts to fix a motor on the floating block; a motor output shaft of the motor downwards penetrates in a shaft hole of the floating block, and downwards extends out of the shaft hole; a spline is arranged at the extension end of the bottom end of the motor output shaft; a quick joint is arranged on a shaft body of the motor output shaft above the spline; and the motor output shaft is matched and connected with a perforation drill bit through the quick joint. The motor directly drives the perforation drill bit, so that the perforationoperation is quickly finished, and perforation is powerful; through arrangement of a pipe orifice ring cutter, perforation edges are uniform without burrs; and a drilling chip channel facilitates removal of dripping chips.

Description

technical field [0001] The invention relates to the technical field of punching equipment, in particular to an edge-type pressure-controlled puncher. Background technique [0002] Generally, most of the hole openers in the prior art commonly used in daily life adopt a hinge structure, such as the hole opener for paper pages adopts the hinge form, and the belt belt hole opener adopts the form of hand-held pliers. The torque of this type of hole saw is mostly based on the lever principle of the body design to realize the hole opening action. Its short moment arm and small torque can provide limited hole opening force, and in many cases it cannot meet the needs of hole opening, or even complete the hole opening action, and cannot completely open the hole. [0003] There is a hand drill type hole saw in the large-scale appliance hole saw of the prior art. The instrument itself is bulky and needs electric power to provide power. Although it can realize fast hole opening, it cann...

AI Technical Summary

Problems solved by technology

The force arm is short and the torque is small, which can provide limited force for opening holes. In many cases, it cannot meet the needs of opening holes, or even complete the opening action, and cannot completely open holes.

[0003] The hole saws for large appliances in the prior art have hand drill type hole saws. The instruments themselves are bulky and require electric power to provide power. Although they can realize fast hole opening, they cannot be carried around at will, nor can they be used flexibly.
