Description

Technical Field

[0001] The present invention relates to the technical field of linear guides, and more particularly to a linear guide module with an oil injection mechanism. Background Art

[0002] Linear guides are used in high-precision or high-speed linear reciprocating motion applications and can bear a certain torque, enabling high-precision linear motion under high loads.

[0003] In the prior art, a linear guide uses an oil guide pipe in cooperation with an oil injection nozzle, facilitating the oil to fall on the surface of the linear guide, thereby playing a certain lubricating role for the linear guide, increasing the movement speed of the moving plate. Since an anti-corrosion paint layer is applied to the linear guide, it can effectively protect the linear guide from corrosion, extend the service life of the linear guide, and a drip tray is provided to collect excess lubricating oil and reduce waste.

[0004] In the prior art, when injecting oil into a linear guide, the lubricating oil is sprayed onto the linear guide through an oil injection nozzle for lubrication, and a drip tray is used to receive the excess lubricating oil. However, when the guide is used for a long time, dust will accumulate on the guide, resulting in impurities in the lubricating oil received by the drip tray, making it difficult to reuse. At the same time, when directly spraying lubricating oil onto the guide through the oil injection nozzle, the lubricating oil coverage on the guide is not thorough enough. Therefore, there is room for improvement. Summary of the Invention

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.

[0041] See also Figure 1 , Figure 5 , Figure 6 , Figure 11 and Figure 12 The mounting structure includes a plurality of slots 38 provided on the inner wall of the rotating sleeve 11, and the slots 38 are provided corresponding to the position of the first oil filling port 10. Two moving blocks 39 are respectively provided in each slot 38 for sliding, and the end faces of the moving blocks 39 and the slots 38 are both in a "T" shape. The mounting block 13 is connected to each group of two moving blocks 39, and second transverse grooves 42 are provided on the inner walls on both sides of the slots 38. A through rod 41 is fixedly passed through the moving block 39 on the left side, and the two ends of the through rod 41 are respectively movably inserted into the second transverse groove 42. An opening 40 connected to the slot 38 is provided on the right end face of the rotating sleeve 11, and a positioning block 57 inserted into the opening 40 is installed on the mounting block 13, and a positioning structure is provided in the opening 40;

A positioning bar 43 is movably inserted into the arc-shaped groove 47. A positioning groove 44 for the positioning bar 43 to pass through is opened on the positioning block 57. A spring is connected between one end of the positioning bar 43 and the end groove wall of the arc-shaped groove 47. A toggle block 46 that is movably connected to the positioning bar 43 passes through the through groove 45. When replacing the oil injection cotton 14 that is full of oil stains after long-term use, the guide rail cover plate 4 can be detached from the guide rail bottom plate 1. By using the corresponding toggle block 46 to drive the positioning bar 43 in the through groove 45 to be withdrawn from the positioning groove 44 of the positioning block 57, the positioning of the mounting block 13 on the rotating sleeve 11 is released. Then, the mounting block 13 can be directly withdrawn from the rotating sleeve 11 by sliding the moving block 39 in the slot 38. When the mounting block 13 is withdrawn to the maximum extent, one of the moving blocks 39 is completely withdrawn from the slot 38, and the other moving block 39 slides to the opening 40. The through rod 41 on the other moving block 39 slides to one end of the second transverse groove 42. In this way, the mounting block 13 can be rotated upward with the through rod 41 as the axis to replace the oil injection cotton 14 in the placement groove 15, making the replacement work of the oil injection cotton simpler and more convenient.

[0043] See Figures 1 - 3 , the dust-proof structure includes L-shaped columns 55 connected to the left and right sides of the guide rail bottom plate 1 near both ends. A rotating cylinder 56 is rotatably sleeved on the L-shaped column 55. Bottom grooves 52 are opened near the left and right sides of the moving seat 3. U-shaped rods 53 are connected to the front and rear sides of the moving seat 3 near the bottom grooves 52. A dust-proof belt 54 passes through the bottom grooves 52. The dust-proof belt 54 is an elastic belt. The dust-proof belt 54 bypasses the rotating cylinder 56. Both ends of the dust-proof belt 54 are connected to the U-shaped rods 53. By using the dust-proof belt 54, dust in the external air can be blocked, reducing the accumulation of impurities such as dust in the external air on the oil-injected guide rail rod, causing difficulties in cleaning and affecting the service life of the guide rail. And by using the rotation of the dust-proof belt 54 around the rotating cylinder 56, the problem that the dust-proof belt 54 hinders the normal movement of the moving seat 3 can be avoided.

[0044] The implementation principle of a linear guide module with an oil injection mechanism in an embodiment of the present invention is as follows: First, since the dust-proof belt 54 is an elastic belt, when adding lubricating oil into the oil storage cavity, directly pry open the dust-proof belt 54 at the moving seat 3, and use an oil injection gun to add lubricating oil into the oil storage cavity through the oil injection nozzle 23. When oil injection is required, open the electric valve on the first oil injection pipe 25 to add the lubricating oil in the oil storage cavity of the oil injection seat 5 into the first oil injection pipe 25. As the moving seat 3 moves, when the moving seat 3 moves, it drives the L-shaped bar 33 and the second insertion rod 36 to move as a whole. When one end of the second insertion rod 36 slides in the lifting groove 37, it can drive the second oil injection pipe 26 to move upward on the first oil injection pipe 25, thereby pushing the plugging block 30 at one end of the L-shaped rod 28 out of the oil leakage groove 31 and releasing the plugging work on the fixed block 29, so that the lubricating oil in the oil storage cavity can smoothly be added from the first oil injection pipe 25 and the second oil injection pipe 26 to the oil injection cotton 14. And when the moving seat 3 drives one end of the second insertion rod 36 to slide into the first horizontal groove 35 and drives the plugging block 30 to move down into the oil leakage groove 31 for plugging. In this way, as the moving seat 3 moves, the first oil injection pipe 25 can be intermittently plugged, so that during the oil injection process, the waste of lubricating oil can be reduced and the oil injection cost can be lowered. At the same time, as the moving seat 3 moves, it drives one end of the first insertion rod 18 to slide in the spiral groove 21, so as to drive the rotating pipe 18 and the first gear 19 to rotate as a whole on the first fixed sleeve 17, and automatically drive the rotating sleeve 11 to rotate on the mounting sleeve 8 through the second gear 22. In this way, during the oil injection process, the oil injection cotton 14 can be driven to closely adhere to the guide rail rod 2 for rotary oil injection, making the oil injection of the guide rail rod 2 more thorough and improving the quality of the oil injection work. In this way, the oil injection work can be realized.

[0045] The above are all the preferred embodiments of the present invention, and the protection scope of the present invention is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
