Description

Technical Field

[0001] The utility model belongs to the technical field of linear guide rails, in particular to a self-lubricating linear guide rail for an ultra-high precision positioning table. Background Art

[0002] Linear guides can be divided into three types: roller linear guides, cylindrical linear guides, and ball linear guides. They are used to support and guide moving parts to perform reciprocating linear motion in a given direction. According to the nature of friction, linear motion guides can be divided into sliding friction guides, rolling friction guides, elastic friction guides, fluid friction guides and other types. In actual use, sliding friction guides will cause wear after long-term use due to sliding friction between the guide and the slider, so self-lubricating linear guides are needed.

[0003] The existing linear guide rails are very inconvenient to use lubricating oil during the lubrication process, and the oil storage tank cannot be quickly installed and disassembled. It is very inconvenient when the oil storage tank needs to be disassembled for maintenance. Long-term use will cause dust and impurities around the oil storage tank, which will affect the lubrication system. The oil storage tank cannot be disassembled, which is very inconvenient to clean.

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] For specific embodiment 1, please refer to Figure 1-5 The utility model is a self-lubricating linear guide for an ultra-high precision positioning table, comprising a guide assembly 1, a mounting assembly 2 and two oil pressure assemblies 3.

Disassembling the oil tank 103 allows the operator to more easily clean the old oil and add new lubricating oil to ensure the good lubrication state of the guide rail. The push plate 302 is pushed by the push rod 301 to squeeze the lubricating oil inside the oil tank 103, which is more convenient when oiling the linear guide rail.

[0031] Specifically: the number of sliding blocks 207 and sliding rods 208 is set to four, and they are respectively arranged on the opposite side of the two tooth plates 205. When the tooth plates 205 move, it is convenient for them to support and limit the tooth plates 205. The number of bearings 209 is set to two. The bearings 209 are movably connected to the rotating rod 202, and the other end is connected to the protective shell 201, so that the rotating rod 202 can be more convenient when rotating. Specific embodiments

[0032] See also Figure 1-5 On the basis of the first and second specific embodiments, grooves are provided on the opposite sides of the two limit blocks 104, the side of the spring 303 close to the oil tank 103 is fixedly connected to the oil tank 103, a positioning block 305 is fixedly installed on the bottom of the push plate 302, and positioning grooves 306 are provided on the front and rear sides of the bottom of the inner cavity of the oil tank 103, and a first sealing ring 307 is fixedly installed on the front and rear sides of the oil tank 103. The inner cavity of the first sealing ring 307 is movably connected to the surface of the push rod 301, and a second sealing ring 4 is provided on the surface of the oil filling pipe 105, and the bottom of the second sealing ring 4 is fixedly connected to the top of the oil tank 103.

[0033] Specifically: the number of positioning blocks 305 and positioning grooves 306 are set to four, and are arranged at the bottom of the push plate 302. When the push plate 302 moves, it is convenient for them to support and limit the push plate 302. The number of first sealing rings 307 is set to four, and are arranged on the surface of the push rod 301, so that the push rod 301 has better sealing performance when in use. The number of second sealing rings 4 is set to two, and are arranged on the surface of the oil filling pipe 105, so that the oil filling pipe 105 has better sealing performance when in use.

[0034] The working principle of the utility model is as follows: two oil storage tanks 103 are inserted from the top of the slide plate 102 to the two sides of the slide plate 102, and the rotating disk 203 is rotated. When the rotating disk 203 rotates, the rotating disk 203 drives the gear 204 to rotate through the rotating rod 202. When the gear 204 rotates, it drives the two tooth plates 205 to move in opposite directions. When the tooth plates 205 move, they drive the clamping block 206 to move, and the clamping block 206 is moved to the groove on the limit block 104, so that the oil storage tank 103 can be quickly installed. When it needs to be disassembled, the rotating disk 203 is rotated in the opposite direction, and the clamping block 206 is moved out of the inner cavity of the limit block 104 to quickly disassemble the oil storage tank 103. Disassembly can facilitate the replacement and maintenance of the lubricating oil. The lubricating oil enters the interior of the oil storage tank 103 through the oil filling pipe 105, and the lubricating oil flows out through the oil outlet 304, thereby lubricating the linear guide rail. By pushing the push rod 301, the push rod 301 drives the push plate 302 to move when pushed, and the lubricating oil is pushed by the push plate 302 to move, which makes it more convenient to oil the linear guide rail. The oil pressure in the oil tank can ensure that a uniform lubricating film is formed between the slide plate 102 of the guide rail and the guide rail body 101, effectively reducing the direct contact between the metal surfaces, thereby reducing the friction coefficient, reducing energy loss, and extending the service life of the guide rail body 101 and the slide plate 102.
