Problems solved by technology

[0008] By setting the carriages on the left and right sides of the headstock, one end of the tool bar is fixed on the carriage I on the right side of the headstock, and the other end of the tool bar is fixed on the left side of the headstock through the central hole of the headstock spindle. Supporting both ends of the tool rod on the carriage II of the tool can solve the problem that the tool rod overhangs due to the large length of the workpiece, resulting in large deflection and deformation of the tool rod and difficult to guarantee the manufacturing accuracy; The two ends of the tool bar are fixed and only let the tool bar move in a straight line, which reduces the vibration and deformation of the tool bar during the processing, which in turn can increase the feed rate of each tool, so that the processing speed is accelerated and the processing efficiency is high.

Abstract

The invention relates to the technical field of machining, in particular to an inner wall machining machine tool. The inner wall machining machine tool comprises a machine tool body, a spindle box and carriages. The carriages comprise the carriage I located on the right side of the spindle box and the carriage II located on the left side of the spindle box. One end of a cutter bar is fixed to the carriage I, and the other end of the cutter bar penetrates through a center hole of a spindle of the spindle box to be fixed to the carriage II. The inner wall machining machine tool has the advantages of being capable of machining long workpieces and high in machining precision and machining efficiency.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to an inner wall processing machine tool and a processing method. Background technique [0002] At present, when processing the inner wall of a large and long workpiece, due to the long through hole of the workpiece, the length of the tool holder must be long enough to complete the processing of the inner wall of the workpiece through hole. One end of the tool is fixed and the other end is suspended. Because the tool bar is too long, the overhang of the tool bar will be lengthened, and the deflection of the tool bar will be large during processing, which is difficult to ensure the manufacturing accuracy; at the same time, the tool bar is too long and it is easy to generate vibration. It is difficult to guarantee the shape and position tolerance, surface roughness and dimensional accuracy of the workpiece; in addition, in the existing processing method, in order to mini...
