Trimming and burr clearing device for orifice

Abstract

The invention discloses a trimming and burr clearing device for an orifice. The trimming and burr clearing device comprises a handle, a rocker arm, a connecting rod, a spindle, a chamfering countersink and a casing. The casing is of a hollow structure, and the spindle is arranged in the casing. One end of the spindle extends out of the casing and is connected with the connecting rod in a transmission mode, and the other end of the spindle extends out of the casing and is connected with the chamfering countersink in a detachable mode. A first through hole is formed in one end of the connecting rod, the spindle penetrates the first through hole and is connected with the connecting rod through a first nut, and the connecting rod can drive the spindle to rotate. A second through hole is formed in the other end of the connecting rod, and one end of the rocker arm penetrates the second through hole and is fixedly connected with the connecting rod through a second nut. The other end of the rocker arm is connected with the handle. The trimming and burr clearing device for the orifice has fewer parts, is simple in structure, small in weight and light in hand holding and can achieve trimming and burr clearing of a screw hole in a deep long shaft hole easily by lengthening the countersink.

Description

technical field [0001] The invention relates to an orifice flash and burr cleaner. Background technique [0002] There are many screw holes and light holes for connection on general mechanical parts, such as: gearboxes, robot components, generator components, etc., which are covered with dozens or even hundreds of screw holes and light holes. After they are processed, there will be flashes and burrs in the holes, which must be cleaned. Usually, these flashes and burrs are cleaned by hand with tools such as abrasive skins, scrapers, files, hand chamfering drills, hook chamfering tools, etc. These tools have the following disadvantages in use: [0003] 1. The production efficiency is low, it takes a lot of working time, and the operator's mood is easy to become irritable, which affects the product quality; [0004] 2. Because the palm is operating with force, it will take longer if there are more holes, and the palm or arm will become sore. It will be more prominent when enc...
