Description

Technical Field

[0001] The invention relates to the technical field of linear guide rails, and in particular to a linear guide rail module with an oil injection mechanism. Background Art

[0002] Linear guides are used for high-precision or high-speed linear reciprocating motion, and can bear a certain torque, and can achieve high-precision linear motion under high load conditions; The linear guide in the prior art uses an oil guide pipe in conjunction with an oil spray nozzle to facilitate the oil to be sprayed onto the surface of the linear guide, thereby facilitating a certain lubrication effect on the linear guide and increasing the movement rate of the moving card. Since the linear guide is coated with an anti-corrosion paint layer, the linear guide can be effectively protected from corrosion and the service life of the linear guide is extended. In addition, an oil receiving groove is provided to collect excess lubricating oil and reduce waste. In the prior art, when the linear guide is filled with oil, the lubricating oil is sprayed onto the linear guide through the oil spray nozzle for lubrication, and the excess lubricating oil is received by the oil receiving groove. However, dust will accumulate on the guide rail when it is used for a long time, which causes the lubricating oil received by the oil receiving groove to contain impurities and is not easy to reuse. At the same time, when the lubricating oil is sprayed directly onto the guide rail by the oil spray nozzle, the guide rail may not be covered thoroughly by the lubricating oil. Therefore, there is room for improvement. Summary of the invention

[0019] The implementation principle of a linear guide rail module with an oil filling mechanism in an embodiment of the present invention is as follows: first, since the dust-blocking belt 54 is an elastic belt, when adding lubricating oil to the oil storage chamber, the dust-blocking belt 54 is directly pulled open at the movable seat 3, and the lubricating oil is added to the oil storage chamber through the oil filling nozzle 23 using an oil filling gun. When oil filling is needed, the electric valve on the first oil filling pipe 25 is opened to add the lubricating oil in the oil storage chamber in the oil filling seat 5 to the first oil filling pipe 25. As the movable seat 3 moves, the movable seat 3 drives the L-shaped strip 33 and the second plug rod 36 to move as a whole when it moves. When one end of the second plug rod 36 slides in the lifting groove 37, it can drive the second oil filling pipe 26 to move upward on the first oil filling pipe 25, thereby pushing the blocking block 30 at one end of the L-shaped rod 28 out of the oil leakage groove 31, releasing the blocking work on the fixed block 29, so that the lubricating oil in the oil storage chamber can be smoothly discharged from the first The oil filling pipe 25 and the second oil filling pipe 26 are added to the oil filling cotton 14, and when the movable seat 3 drives one end of the second plug rod 36 to slide into the first transverse groove 35 to slide, the blocking block 30 is driven to move down into the oil leakage groove 31 for blocking. In this way, as the movable seat 3 moves, the first oil filling pipe 25 can be intermittently blocked, thereby reducing the waste of lubricating oil and reducing the oil filling cost during the oil filling process. At the same time, the movement of the movable seat 3 drives one end of the first plug rod 18 to slide in the spiral groove 21, to drive the rotating tube 18 and the first gear 19 to rotate as a whole on the first fixed sleeve 17, and the second gear 22 automatically drives the rotating sleeve 11 to rotate on the mounting sleeve 8. In this way, during the oil filling process, the oil filling cotton 14 can be driven to rotate and fill oil against the guide rail rod 2, so that the guide rail rod 2 is filled with oil more thoroughly, and the quality of the oil filling work is improved, so that the oil filling work can be realized.

[0020] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
