Problems solved by technology

[0002] During the internal thread processing of the workpiece, due to the hole position and depth size, etc., it is difficult to remove the internal thread tooth profile burrs.
Especially when it comes to internal threads of deep holes or complex shells, the fitter usually uses taps or self-made scrapers to process them. When processing with taps, the effect of removing burrs is not good due to the tolerance of the bottom diameter hole of the internal threads, and it is easy to use a scraper to process. The thread is damaged and the removal effect is not good, and the processing efficiency is low

Abstract

The invention discloses an adjustable internal thread deburring device which comprises a screw rod (1) and is characterized in that a mounting groove (8) is formed in the bottom of the screw rod (1), a guide blade (2) is arranged in the mounting groove (8), the guide blade (2) is connected with a spring (3), and the other end of the spring (3) is connected with a plug (4). The device has low requirements on machining environments such as the appearance and the thread position of a machined workpiece, and the process operability is high; the use is convenient, the thread is not easy to scratch, and smooth transition between thread forms is realized. The problem that parts such as screws cannot be taken out due to clamping stagnation of burrs after being screwed into internal threads is solved. And when internal threads with the same specification are machined, the influence of the diameter of a bottom hole of the internal threads is avoided, the cutting force of the adjustable plug and the spring on the guide blade is automatically adjusted, and the flexibility is high.

Description

technical field [0001] The invention relates to a technology for removing burrs from tooth profiles of internal threads in mechanical processing, in particular to an adjustable deburring device for internal threads. Background technique [0002] During the internal thread processing of the workpiece, due to the hole position and depth size, etc., it is difficult to remove the internal thread tooth profile burrs. Especially when it comes to internal threads of deep holes or complex shells, the fitter usually uses taps or self-made scrapers to process them. When processing with taps, the effect of removing burrs is not good due to the tolerance of the bottom diameter hole of the internal threads, and it is easy to use a scraper to process. The thread is damaged and the removal effect is not good, and the processing efficiency is low. To solve the above problems, a tool that can be automatically adjusted in the thread bottom hole is made to remove thread burrs and improve thre...
