Rotary trimming and chamfering device capable of being used obversely and reversely

Abstract

The invention discloses a rotary trimming and chamfering device capable of being used obversely and reversely and provides a burr trimming tool. According to the burr trimming tool, operation is easy and convenient, the other finish-machined surfaces are not prone to scratches, the machining efficiency is high, and the surfaces are smooth after burr treatment. According to the technical scheme, the front end of a tool bar guiding body (2) is provided with a hole access guiding body; an L-shaped cutting tool (4) passes through a radial through hole of the hole access guiding body in the radial direction in a length-adjustable mode, and chamfering blades are manufactured on the two sides of a tool bit of the L-shaped cutting tool; the cutting edge of the L-shaped cutting tool is locked and fixed in the axial direction through a locking bolt (5) after being turned downwards or upwards. The rotary trimming and chamfering device is mainly used for removing burrs, which cannot be turned easily, on a rotary surface, and the burrs can be removed manually and can also be removed on a vertical drilling machine. When the rotary trimming and chamfering device is in use, the corresponding tool bar guiding body is selected or a proper hole guiding bush is assembled according to the size of an inner hole of a part, and the burrs are removed through rotary cutting after the position of the cutting tool is adjusted and fixed according to the positions of the burrs.

Description

technical field [0001] The invention relates to a non-standard tool for chamfering and deburring the double-sided, internal and external hole walls of cylinders and various valve body holes, especially the chamfering of small hole walls, which cannot be completed by traditional tools in mechanical manufacturing. Background technique [0002] Right-angle burrs, groove burrs, outer circles, inner holes, cross holes, counterbores and other burrs that are inevitable in the production process of metal parts or plastic parts. After automatic or semi-automatic large-scale processing of metal parts or plastic parts, many products need to clean the surface burrs, use files and sandpaper to polish, the efficiency is low, and the surface after treatment is rough. Using the rotary deburring mechanism of the upper machine equipment, it is necessary to replace the precision cutter head for repair, which is time-consuming and laborious. In recent years, aviation products have been continu...

Problems solved by technology

[0003] The purpose of the present invention is to aim at the sharp edge of the outer disk of the non-cylindrical inner and outer hole walls, the bearing closure, the double-ear cylinder body and the double-ear tailstock parts U-shaped groove inside the inner guide hole bushing and the outer disk sharp edge, especially the non-turning inner and outer holes End burr repairing, file polishing, manual operation is inconvenient, and it is easy to damage the finishing plane. We provide a flip-type positive and negative repairing machine with simple and convenient operation, which is not easy to scratch the rest of the finishing surface, high processing efficiency, and has a smooth surface after burr treatment.
