Description

Technical Field

[0001] This utility model relates to the field of linear guide rail technology, and in particular to a linear guide rail with a lubrication and leak-proof structure. Background Technology

[0002] Linear guideways are precision guiding components widely used in mechanical transmission systems, primarily for achieving high-precision, low-friction linear motion. Their core structure typically consists of a guide rail, a slider, and rolling elements (such as balls or rollers). They are characterized by high rigidity, high load capacity, and long service life, and are widely used in CNC machine tools, automation equipment, robotics, semiconductor manufacturing, medical devices, and other fields.

[0003] The key bottleneck of existing linear guide rail technology lies in the insufficient long-term maintenance capability of its lubrication system. Traditional lubrication designs mostly adopt periodic manual oiling, which makes it difficult to achieve continuous lubrication of the friction interface. This leads to the problem of rapid lubricant consumption during long-term operation of the guide rail system, which in turn shortens the service life and restricts the performance improvement of linear guide rails. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a linear slide rail with a lubrication and leakage prevention structure.

[0005] An embodiment of this utility model provides a linear slide rail with a lubrication and leak-proof structure, comprising:

[0006] A slide rail body, on which a slide block is slidably disposed;

[0007] The bottom of the slide rail body is provided with an installation groove, and lubrication components are provided on both sides of the installation groove. The lubrication components include an oil tank, a positioning groove, an oil delivery cylinder, a spring, and a movable block. The oil tank is connected to the positioning groove. The oil delivery cylinder is fixedly installed on one side of the positioning groove and is fixedly installed through one side of the slide rail body. The positioning groove is provided with a through hole through the oil delivery cylinder. An oil outlet is provided through the outer side of the oil delivery cylinder. The spring is fixedly installed on one side of the positioning groove and is installed inside the oil delivery cylinder. A movable block is fixedly installed at the other end of the spring, and the ball bearing is slidably embedded in the outer side of the movable block.

[0024] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0025] like Figures 1-5 As shown, this utility model embodiment proposes a linear slide rail with a lubrication and leak-proof structure, comprising:

[0026] The slide rail body 1 has a sliding block that can be driven to move on the slide rail body 1.

[0027] The bottom of the slide rail body 1 is provided with a mounting groove 2, and lubrication components are provided on both sides of the mounting groove 2. The lubrication components include an oil tank 3, a positioning groove 7, an oil delivery cylinder 8, a spring 12, and a movable block 13. The oil tank 3 is inclined so that the lubricating oil in the oil tank 3 can flow to the tank opening, and the lubricating oil is automatically replenished by gravity. The oil tanks 3 on both sides are arranged opposite each other.

[0028] The oil tank 3 is connected to the positioning groove 7. The oil delivery cylinder 8 is fixedly installed on one side of the positioning groove 7 and is also fixedly installed through one side of the slide rail body 1. The connection structure ensures that the oil passage is unobstructed. The positioning groove 7 is provided with a through hole 11 through the oil delivery cylinder 8. The through hole 11 is used for the passage of lubricating oil and is a key channel for the flow of lubricating oil. An oil outlet 9 is provided through the outside of the oil delivery cylinder 8. The oil outlet 9 is used for the overflow of lubricating oil to directly supply oil to the friction parts.

[0029] Spring 12 is fixedly mounted on one side of positioning groove 7 and is located inside oil delivery cylinder 8. A movable block 13 is fixedly mounted on the other end of spring 12, allowing the movable block 13 to be elastically connected to the oil delivery cylinder 8 via spring 12, providing pressure. Ball bearings 14 are slidably embedded on the outside of the movable block 13 and roll within it, providing both sealing and reducing friction. The movable block 13 abuts against the inside of the oil delivery cylinder 8, and the ball bearings 14 are located inside the oil outlet 9, allowing the movable block 13 to block the oil outlet 9, initially preventing lubricant leakage in a sealed state.

[0030] A connecting assembly is used to connect the oil tank 3 to the positioning groove 7. The connecting assembly includes a mounting plate 4 and two spring clips 17. The opening of the oil tank 3 passes through the mounting plate 4 and is fixedly installed. Both ends of the mounting plate 4 are provided with locking holes 6. The mounting plate 4 serves to position and support the load. A locking groove 10 is provided on one side of the positioning groove 7. The mounting plate 4 is set in the positioning groove 7 through the locking groove 10, which provides installation guidance and limitation.

[0031] An extrusion strip 15 is fixedly installed on the inner side of the positioning groove 7. One end of the extrusion strip 15 is set at an angle, so that when the mounting plate 4 is inserted into the positioning groove 7, the extrusion strip 15 squeezes the mounting plate 4, making it abut against the positioning groove 7. The angled surface guides the self-tightening function. A sealing gasket 5 is fixedly installed on one side of the mounting plate 4. The sealing gasket 5 abuts against the inner side of the positioning groove 7. The sealing gasket 5 plays a sealing role to prevent lubricating oil from leaking out.

[0032] Both sides of the positioning groove 7 are provided with limiting holes 16. Two spring pieces 17 are fixedly installed in the two limiting holes 16 respectively. A retaining ball 18 is fixedly installed on the inner side of the spring piece 17, so that the retaining ball 18 can be pushed outward and can be inserted into the retaining hole 6, thereby fixing the mounting plate 4. The retaining ball 18 structure provides a reliable quick installation and quick removal function.

[0033] The detailed working process of this utility model is as follows:

[0034] 1. During installation, insert the oil tank 3 into the mounting groove 2 and insert the mounting plate 4 into the positioning groove 7; at the same time, the extrusion strip 15 will extrude the mounting plate 4, thereby pressing the sealing gasket 5 against the inside of the positioning groove 7; when the locking ball 18 is extruded into the locking hole 6, the mounting plate 4 can be locked, thereby fixing the oil tank 3 in place.

[0035] 2. During use, the lubricating oil in the oil tank 3 will flow into the oil delivery cylinder 8. When the slide passes over the ball 14, it will squeeze the ball 14 inward and push the movable block 13 to separate from the inside of the oil delivery cylinder 8. At this time, the lubricating oil in the oil delivery cylinder 8 will seep out through the gap to lubricate the slide. By slowly discharging the lubricating oil, the continuous lubrication effect is ensured and the service life is extended.

[0036] 3. When disassembling, pull the oil tank 3 and the mounting plate 4 outward to separate the retaining ball 18 from the retaining hole 6, and then pull out the oil tank 3 to replace or refill the lubricating oil.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
