Abstract

The invention relates to a guide structure of a piston rod of a nitrogen gas balanced oil cylinder. The guide structure comprises a cylinder barrel, the piston rod, a front end cover and a guide sleeve, wherein the front end cover is fixed at the front end of the cylinder barrel; the piston rod is mounted in the cylinder barrel and passes through the front end cover; the guide sleeve is mounted between the front end cover and the piston rod; a dustproof cap is mounted between the guide sleeve and the piston rod; and a sealing ring is mounted between the front end cover and the piston rod. According to the guide structure, the dustproof cap is arranged at the front end of the guide sleeve and the sealing ring is arranged at the back end of the guide sleeve, so the sealing performance is good, dust cannot fall into the cylinder barrel and the service life of the oil cylinder is prolonged.

Description

technical field [0001] The invention relates to a nitrogen balance system for a spindle counterweight of a machine tool machining center, in particular to a guide structure for a nitrogen balance oil cylinder piston rod. Background technique [0002] The nitrogen balance system of the machine tool machining center replaces the traditional spindle counterweight counterweight, which not only reduces the resource consumption of raw materials, reduces the total weight of the machine tool, but also reduces the micro-vibration generated by the spindle movement, and improves the product quality. precision. [0003] For the oil cylinder in the nitrogen balance system, a guide sleeve is arranged between the front end cover of the cylinder barrel and the piston rod to seal and support the piston rod. The existing guide sleeve has poor sealing performance, thereby affecting the service life of the oil cylinder. Contents of the invention [0004] In view of the above problems, the p...
