Automatic grease injection mechanism for outer frame of slide track

Abstract

The invention relates to an automatic grease injection mechanism for an outer frame of a slide track. The automatic grease injection mechanism comprises a cylinder, an air claw and nozzles, wherein the cylinder is in driving connection with a moving rack; the air claw is arranged on the moving rack; two nozzles which are symmetrically distributed are arranged on the air claw through a nozzle bracket; the appearances of the two nozzles accord with the internal shape of the outer frame of the slide track; four oil jet holes which are distributed in angles of 90 degree are arranged at corner parts on the two nozzles; and a grease pipeline of an oil feeding system is communicated with the nozzles through oil valves. According to the automatic grease injection mechanism, grease is uniformly injected into four corners of the almost sealed outer frame of the slide track in an extremely small space, and the grease injection precision is ensured; and when the air claw is opened, the two nozzles are adhered to the inner wall of the outer frame of the slide track, thereby ensuring that the grease can be well injected into the four corners of the frame body.

Description

technical field [0001] The invention relates to an automatic oiling device, in particular to an automatic grease filling mechanism for the outer frame of a slide rail, which is used for automatically injecting grease to the four corners inside the outer frame of the slide rail. Background technique [0002] The lubrication of the slide rail steel ball is the core technology of the slide rail. The precision of the grease determines the sliding effect and service life of the slide rail. [0003] With the continuous updating of products, the previous one-sided volleyball slide rail can no longer meet the needs of the society, not only cannot meet the demand for increased bearing capacity, but also cannot adapt to the balance of sliding. In the past production, oil leakage often occurred in the oil circuit and the phenomenon of oil leakage continued after filling the oil. [0004] At present, the current production method cannot be used for the four-row steel ball slide rail. T...
