Stable-performance automatic resilience deburring cutter for industrial drilled hole

Abstract

The invention discloses a stable-performance automatic resilience deburring cutter for an industrial drilled hole. The cutter comprises two single blade bodies, wherein two corresponding ends of the two single blade bodies are hinged through a pivotal shaft; each of the two single blade bodies comprises a rotary part, an expansion part and a strength-bearing part; the rotary parts are hinged to the pivotal shaft; the expansion parts are arranged at the rear ends of the rotary parts; a return spring in a compression state is arranged between the expansion parts of the two single blade bodies; the strength-bearing parts are arranged at the rear ends of the expansion parts; elasticity rings are arranged on the outer side walls of the strength-bearing parts of the two single blade bodies; cutting blades are arranged on the outer side walls of rear ends of the strength-bearing parts. The stable-performance automatic resilience deburring cutter overcomes the defects that elastic force of an elasticated arm of the existing deburring cutter is prone to attenuation and is instable in performance; the return spring is arranged, and elastic force of the return spring is utilized to enable the cutting blades to cling to the inner wall of an industrial drilled hole, so that the deburring effect is ensured.

Description

technical field [0001] The invention relates to the technical field of deburring tools, in particular to an automatic springback deburring tool for industrial drilling with stable performance. 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 "An Automatic Rebound 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 knife bar, and a cutting edge on the outer periphery of the elastic arm. Internal deformation to meet the needs of industrial drilling deburring in different hole diameter ranges. However, in daily use, the elastic force of the elastic arm...

AI Technical Summary

Problems solved by technology

The invention overcomes the defects that the elastic force of the elastic arm of the existing deburring tool is easy to attenuate and the performance is not stable enough. By setting the return spring, the elastic force of the return spring is used to make the cutting edge close to the inner wall of the industrial drilling to ensure the deburring effect
