Precision blind hole key groove cutting machine

Abstract

The invention relates to a precision blind hole key groove cutting machine. The cutting machine comprises a workpiece positioning guide sleeve, a socket head cap screw, a cutting head, a feeding rod, a main rod, a cutter bar body, a spring, a transmission handle, a servo motor, a screw, a servo motor support, a fixed connection flat key, an axially sliding coupler, a sliding connection flat key, a conical handle, a conical handle positioning screw, a main rod positioning screw, a spring piece fixing screw, a spring piece, a fixing plate, a main movement guide rod, a guide sleeve fixing plate, a guide sleeve, a bidirectional hydraulic main cylinder, a machined part, a workpiece positioning clamp, a control cabinet and a rack. The cutting machine is characterized in that a workpiece is positioned by the workpiece positioning guide sleeve, only the cutting head performs radial displacement for adjustment during multi-cutting feed, the workpiece positioning guide sleeve does not perform radial displacement, the servo motor drives feed, the bidirectional hydraulic main cylinder is used for cutting, and the cutting process is controlled through numerical control programs. The precision blind hole key groove cutting machine is reasonable in design, compact in structure and high in machining precision and definitely becomes the best blind hole key groove finish machining machine.

Description

technical field [0001] The invention relates to a precision blind hole keyway cutting machine. Background technique [0002] At present, the machine tools used for blind hole keyway processing in metal cutting machine tools are mainly slotting machines and planers. There are two problems in the processing of keyways in these two types of machine tools: one is the correction and adjustment of the position relationship between the workpiece and the tool before processing, and the other is machining accuracy. Difficult to guarantee (mainly dimensional accuracy, symmetry and surface roughness), for processing parts with high precision requirements, very few domestic enterprises have to spend huge sums of money to import precision CNC blind hole keyway processing machine tools from abroad, and most enterprises due to insufficient funds Hope to stop, restricting the development of my country's machinery manufacturing industry as a whole.
