A deburring device for orifice of cylindrical parts

Abstract

The invention discloses a tubular part orifice deburring device. The tubular part orifice deburring device comprises a file module, a spring and a mounting member capable of rotating around the axis of a tubular part; the end surface of the mounting member, which faces towards the orifice of the tubular part, is provided with a tool groove extending the axial direction of the tubular part; one endof the file module, which faces toward the orifice of the tubular part, extends into the tool groove and is hinged to the mounting member at a hinge point, one end of the file module, which backs tothe orifice of the tubular part, extends out of the tool groove and is fixedly connected to one end of the spring, and the other end of the spring is fixedly connected with the mounting member; the file module can swing around the hinge point, and inside the tool groove a yielding space for the file module to swing around the hinge point is formed. When the tubular part orifice deburring device isin work, the spring drives the file module to produce working pressure onto the orifice of the tubular part; due to the fact of being capable of flexibly rotating around the hinge point inside the tool groove and with the spring providing the rotating force, the file module can ensure high-efficiency and effective removal of burrs of the orifice of the tubular parts and meanwhile avoid hard scratching of the tubular part.

Description

technical field [0001] The invention belongs to the technical field of machining parts grinding, and in particular relates to a device for deburring holes of cylindrical parts. Background technique [0002] There are many burrs in the inner hole of the end surface of the cylindrical parts after the head is cut, and the hole burrs need to be dealt with. At this stage, manual methods are often used to remove burrs from the orifice of cylindrical parts in machining, which has low removal efficiency, poor removal effect and high labor intensity. [0003] CN207120121U discloses a polishing grinding head for the deburring of the orifice of the inner hole of the steel pipe, and CN207522241U discloses a self-centering polishing device for the deburring of the orifice of the inner hole of the steel pipe. However, the practice shows that the conical grinding head is in rigid contact with the part orifice, and it is easy to cause hard damage to the part orifice during the working proc...

At present, manual methods are often used to remove burrs from the orifice of cylindrical parts in mechanical processing, which has low removal efficiency, poor removal effect and high labor intensity.

[0003] CN207120121U discloses a polishing grinding head for the deburring of the orifice of the inner hole of the steel pipe, and CN207522241U discloses a self-centering polishing device for the deburring of the orifice of the inner hole of the steel pipe. However, the practice shows that the conical grinding head is in rigid contact with the part orifice, and it is easy to cause hard damage to the part orifice during the working process, which will affect the product quality and even lead to an increase in the scrap rate
