Double cutting feed rotating seal main shaft of honing machine

Abstract

The invention relates to a main shaft for machine tool, in particular to the double-feeding rotary sealing main shaft of a honing machine; the main shaft comprises a main shaft which can be fixed in a main shaft box in a rotary mode, and a main shaft sleeve sleeved on the main shaft by moveable connection. The main shaft of the invention is characterized in that the main shaft is a hollow shaft; the upper end of the main shaft can be fixed on a supporting frame in a rotary mode, and the lower end of the main shaft can be fixed on the main shaft box in a rotary mode; a rough honing feed cylinder and a finish honing feed cylinder are fixedly arranged on the supporting frame arranged at the upper end of the main shaft and are concentric with the main shaft; a finish honing push rod in the finish honing feed cylinder is sheathed in a hollow rough honing push rod for rough honing feed cylinder, and the finish honing push rod and the hollow rough honing push rod are arranged in the hollow main shaft; a reciprocating cylinder which drives the main shaft to make reciprocating beeline motion is fixed on the main shaft box, and the upper end of a piston rod in the reciprocating cylinder is fixedly connected to the supporting frame. As the structure and the motion form of the main shaft are changed, the problem of oil leakage of a sealing clamp for honing machine is fundamentally solved. Thus, the structure of the sealing clamp and that of the main shaft become simpler and more reasonable.

Description

Technical field [0001] The invention relates to a machine tool spindle device, in particular to a double-feed rotary sealed spindle of a honing machine. Background technique [0002] The honing machine tool realizes the honing process of hole parts through the rotation and reciprocating linear motion of the grinding head. At present, the rotation of the main shaft of the honing machine tool is driven by the gear that is fixedly installed on the main shaft sleeve and meshed with the internal gear of the gearbox to drive the main shaft sleeve to rotate. card head. A feeding mechanism is assembled on the sealing chuck, and the feeding mechanism is composed of a rough honing feeding oil cylinder and a fine honing feeding oil cylinder. Driven by the rough honing feed cylinder and the fine honing feed cylinder respectively, they move radially to realize the honing of the hole. Because the above-mentioned structure is very complicated, it brings a lot of inconvenience to process...

AI Technical Summary

Problems solved by technology

Because the above-mentioned structure is very complicated, it brings a lot of inconvenience to processing, manufacturing, assembly and use, especially the rough honing feed cylinder and the fine honing feed cylinder on the sealing chuck will rotate with the main shaft, and the sealing device will be damaged after being used for a period of time. , there will be oil leakage, which will affect the normal operation of the sealing chuck, so that the sealing device needs to be replaced frequently
