Cutting tool for boring inner hole groove

Abstract

The invention discloses a cutting tool for boring an inner hole groove. The cutting tool can be used for directly boring the inner hole groove without taking off a workpiece after the inner hole process is performed on a drilling machine or a milling machine. The cutting tool for boring the inner hole groove comprises a cutter bar and a tool bit, wherein the tool bit is inserted in a square hole of the cutter bar in a sliding fit way; the upper end of the tool bit is connected with a cutting feed shifting fork; the cutting feed shifting fork toggles the tool bit to move axially along a boringtool bar to bore the inner hole groove; the cutting feed shifting fork is hinged with the cutter bar through a hinged shaft; the cutting feed shifting fork abuts against a sliding sleeve; the slidingsleeve is in sliding fit connection with the cutter bar; the shifting fork connected with the sliding sleeve is arranged at the lower end of a threaded rod; the threaded rod is connected with a fixedseat with nuts; the fixed seat is arranged on the cutter bar through a shaft; the lower part of the cutting feed shifting fork is provided with a spring; and a guide sleeve and a guide post are arranged on one side of the fixed seat to play an auxiliary guide role and prevent safety accidents caused by that the fixed seat rotates along with the cutter bar.

Description

technical field [0001] The invention relates to a machine tool, in particular to a boring tool for machining inner hole grooves by a drilling machine or a milling machine. Background technique [0002] The processing of the inner hole groove is generally done on the drilling machine or milling machine first, and then transferred to the boring machine to process the inner hole groove. This processing method has secondary card loading and secondary alignment, which is not only labor-intensive and time-consuming, but also has low production efficiency, and is prone to secondary alignment errors, which affect the processing quality. If the volume of the part to be processed is large, it is also limited by the table of the boring machine, and sometimes it cannot be processed. SUMMARY OF THE INVENTION [0003] In order to solve the problems of the prior art, the present invention provides an inner hole groove boring tool, which can be used to directly bore the inner hole groove...

AI Technical Summary

Problems solved by technology

This processing method has secondary clamping and secondary alignment, which is not only labor-intensive and time-consuming, but also has low production efficiency, and is prone to secondary alignment errors, which affect the processing quality.

If the part to be processed is large in size, it is also limited by the worktable of the boring machine, and sometimes it cannot be processed
