Numerical control deep hole keyway milling machine

Abstract

The invention discloses a numerical control deep hole keyway milling machine and belongs to the technical field of machine tools. A working table is mounted on the tool body of the machine tool; a servo tailstock is fixedly mounted at the front end of the working table; a main transmission case is arranged on the rear of the tool body of the machine tool; a cantilever boring frame stretching forward is arranged on the main transmission case; a machine tool electric cabinet and a machine tool control panel are arranged on the two sides of the main transmission case; a hydraulic station is arranged outside the front end of the tool body of the machine tool; the length of the cantilever boring frame is greater than 10 times of the radial size of the cantilever boring frame; a milling axle boxdriven by the main transmission case to move front and back is arranged in the cantilever boring frame; the power source of the milling spindle of the milling axle box is also from the main transmission case outside the cantilever boring frame; a workpiece is hoisted and placed on a support frame, the working table is moved backwards to enable the deep hole of the workpiece to be arranged outsidethe cantilever boring frame in a sleeving manner and to connect the front end of the cantilever boring frame with the tailstock at the front end of the working table; a cutter feeding size is manually adjusted; the cutter is controlled to operate through the main transmission box; and the milling axle box is controlled to move to the front end from the rear end of the deep hole workpiece throughthe main transmission box so as to realize a deep hole milling groove.

Description

technical field [0001] The invention relates to a numerical control deep hole keyway milling machine, which belongs to the technical field of machine tools. Background technique [0002] The grooving of deep holes of workpieces with relatively large length and diameter has always been a difficult problem in domestic machining, especially large workpieces with a deep hole length to diameter ratio of more than ten times. For example, for a workpiece with a length of 5 meters and a deep hole with an inner hole diameter of 0.5 meters, existing machine tool tools cannot be processed in the elongated hole. At present, known deep hole processing machine tools can only process deep holes with a diameter of more than 1 meter, but the processing depth is less than ten meters. [0003] Domestic milling of large and ultra-deep inner hole keyways can only be done manually or semi-mechanically, or the workpiece is processed in sections. The precision of segmented groove lines is suffici...

AI Technical Summary

Problems solved by technology

The accuracy of segmented groove lines is sufficient, but it is difficult to ensure the consistency of multi-segment groove lines, and it is difficult to ensure the accuracy of key grooves through manual and semi-mechanical processing.

It not only increases the labor intensity of the staff, reduces the processing efficiency of the factory, but also cannot meet the needs of the market
