Description

Technical Field

[0001] The utility model relates to the technical field of linear modules, in particular to an externally oil-injected linear module. Background Art

[0002] Linear modules usually have several names, such as linear modules, Cartesian robots, linear slides, etc. They are automated upgrade units following linear guides and ball screw linear drive mechanisms. Linear modules can achieve linear and curvilinear motions of the load through the combination of various units, making the automation of light loads more flexible and positioning more accurate. The module device mainly plays a driving role. After long-term operation, it needs to be oiled for maintenance. The conventional oiling method is to oil through the oil injection holes opened on the fixed structure sleeved on the sliding rod, allowing the lubricating oil to penetrate into the position slidingly connected to the sliding rod, so that the linear module slides more smoothly on the sliding rod. The existing oiling method requires the disassembly of most parts of the module to oil the fixed structure sleeved on the sliding rod, which is rather troublesome and not convenient for maintenance.

[0003] Therefore, it is necessary to provide a new externally oil-injected linear module to solve the above technical problems. Summary of the Utility Model

The front end of the rotating shaft is fixedly connected to a sealing cover at the lower end opening of the storage cavity. The rear side of the rotating shaft penetrates to the outside of the rear side of the mounting seat and is fixedly connected to a pressing rod. A flow pipe is connected and fixedly connected from the lower end of the storage cavity to the center where the fixed sleeve is sleeved on the sliding rod.

[0008] Preferably, sliding sleeves are movably connected in parallel through fixing bolts at the upper and lower openings of the sliding hole. The fixed sleeve can be sleeved and fixed on the sliding rod through the provided sliding sleeves.

[0009] Preferably, limiting blocks are symmetrically and fixedly connected to both sides of the front end surface of the mounting seat. The provided limiting blocks can prevent the mounting seat from being worn when installing the module.

[0010] Preferably, multiple groups of mounting holes are opened on the limiting blocks. The provided mounting holes can facilitate the installation of the module.

[0011] Preferably, limiting posts are fixedly connected in a parallel and symmetric manner at the rear of the upper and lower ends of the fixed sleeve. The provided limiting posts can limit the position when the fixed sleeve slides to the edge of the slide rail.

[0012] Preferably, limiting plates are fixedly connected to the centers of the inner walls on both sides of the slide rod. The provided limiting plates can position the fixed sleeve.

[0013] Preferably, sliding hooks are fixedly connected in a parallel and symmetric manner on the outer sides of the centers of both sides of the fixed sleeve.
