Problems solved by technology

[0004] 1. During the operation process, due to the inconsistency and large fluctuations in the magnitude and direction of the driving force manually applied to the tool, it is easy to cause incomplete burr removal, resulting in the absence of product quality, and the process capability cannot be guaranteed during mass production
[0005] 2. Every time the tool is deburred, the position of the tool relative to the part fluctuates greatly. During the operation, the tool body contacts the inner hole wall of the part and scratches the inner hole wall of the workpiece, which affects the product quality
[0006] 3. The operator is prone to fatigue and negligence during mass production, so that the quality of deburring of parts cannot be guaranteed, and the labor intensity of the operator is increased
[0007] 4. The processing efficiency of manual operation is very low, which is not conducive to mass production

Abstract

The invention discloses a tool for processing burrs at a through position of a through hole, and belongs to the technical field of machining. The tool mainly consists of a tool body, a cutting body and connecting screws. The tool has compact structure, good consistency of removing the burrs and high product burr removal quality, reduces the processing cost, lightens the labor intensity of an operator, and the like. The tool can be widely applied in processing of the removed burrs at the through position of the through hole in machining.

Description

1. Technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a tool for removing burrs at intersecting parts of mechanical processing intersecting holes. 2. Background technology [0002] Tools for removing burrs at intersecting holes are mainly used in the field of machining. During the machining process, when the machining inner hole intersects with other inner holes, processing burrs will be generated at the intersection of the two holes. In some precision parts, burrs will seriously affect the accuracy and life of the parts. During the assembly process, the burrs will fall to the positioning surface, which will cause inaccurate positioning of the parts and produce waste products. Especially, the oil of precision parts that uses the inner hole as the oil path will take away the burrs. Access to precision parts such as bearings and friction parts will cause abnormal wear or direct damage, and at the same tim...
