Lead screw sliding rail with lubricating oil path

Abstract

The invention aims to provide a lead screw sliding rail which is simple and rapid in lubricating oil supplementing operation. The lead screw sliding rail comprises a sliding seat, a lead screw and a sliding block, the lead screw is rotatably matched in the sliding seat, the sliding block is in sliding fit with the sliding seat, a lead screw nut matched with the lead screw is arranged in the sliding block, the top of the sliding seat is provided with a covering sheet matched with the sliding block, a fixing block is arranged at the end part of the sliding block, the lead screw nut is fixed in the fixing block, an oil injection hole is formed in the side end of the sliding block, an oil inlet cavity is formed in the fixing block, the oil injection hole is in communication with the oil inletcavity through an oil conveying channel, an oil guide groove is formed in the outer wall of the lead screw nut, the bottom of the oil inlet cavity is in communication with the oil guide groove, and alead screw oil inlet hole communicating with the inner wall of the lead screw nut is formed in the upper half part of the oil guide groove. The lead screw sliding rail is applied to the technical field of screw transmission mechanisms.

Description

technical field [0001] The invention is applied to the technical field of screw transmission mechanisms, and in particular relates to a screw slide rail with its own lubricating oil passage. Background technique [0002] The linear modules on the market include synchronous belt type and lead screw type. Among them, the lead screw type is composed of a motor and a lead screw slide rail assembly. The motor drives the lead screw to rotate, and then drives the lead screw nut fitted on the lead screw to move Rotary motion is converted to linear motion. In order to ensure the smooth operation between the screw and the screw nut, it is necessary to supplement the lubricating oil to the screw slide rail. At the same time, the lubricating oil also needs to be added between the slider and the sliding seat of the screw slide rail assembly. However, the traditional screw The slide rail assembly needs to dismantle the end and top parts to refill the lubricating oil, which is a cumbersom...

Problems solved by technology

In order to ensure the smooth operation between the screw and the screw nut, it is necessary to supplement the lubricating oil to the screw slide rail. At the same time, the lubricating oil also needs to be added between the slider and the sliding seat of the screw slide rail assembly. However, the traditional screw The slide rail assembly needs to remove the end and top parts to replenish the lubricant, which is a cumbersome operation
