Industrial drill hole deburring tool with small damage and good deburring effect

Abstract

The invention discloses an industrial drill hole deburring tool with small damage and a good deburring effect. The deburring tool comprises two cutter strip single bodies. One ends of the two cutter strip single bodies are hinged simultaneously through a pivotal shaft. Each cutter strip single body comprises a rotary part, an expansion part and a force bearing part, wherein the rotary part is hinged to the pivotal shaft, and the expansion part is arranged at the rear end of the rotary part. A telescopic gasbag is arranged between the expansion parts of the two cutter strip single bodies. An expansion gasbag is connected to the telescopic gasbag. The force bearing parts are arranged at the rear ends of the expansion parts. The outer side walls of the two cutter strip single bodies are sleeved with elastic force rings correspondingly. Cutting edges are arranged on the outer side walls of the rear ends of the force bearing parts. According to the deburring tool, through expansion of the expansion gasbag, the tension of the telescopic gasbag to the expansion parts is effectively relieved, the effects that the acting force of the cutting edges to the inner wall of an industrial drill hole is enough but not too large are ensured, and large damage does not occur to the inner wall of the industrial drill hole while the deburring effect is ensured.

Description

technical field [0001] The invention relates to the technical field of deburring tools, in particular to a deburring tool for industrial drilling with less damage and excellent deburring effect. Background technique [0002] The surface of the existing workpiece often needs to process holes, and the holes are generally processed by drilling. The inner wall and edge of the processed hole often have burrs, which requires secondary processing of the edge and inner wall of the hole. At present, the burrs of the machined holes are often removed by deburring knives. Taking "A Deburring Tool" with the application number CN201410242606.6 as an example, the existing deburring tools often use an elastic arm at the front end of the blade, and a cutting edge on the outer periphery of the elastic arm. Adapt to the needs of industrial drilling deburring in different hole diameter ranges. However, in daily use, when the caliber of the industrial drill hole is small, the elastic arm needs...

AI Technical Summary

Problems solved by technology

The invention overcomes the defect that the existing deburring tool easily causes a large loss to the inner wall when deburring the industrial drilling with a smaller aperture, and effectively relieves the tension of the telescopic airbag on the expansion part through the expansion of the inflatable airbag, ensuring that the cutting edge is right The force on the inner wall of the industrial drilling is sufficient but not too large. While ensuring the deburring effect, it will not cause major damage to the inner wall of the industrial drilling
