With the continuous progress of industrial technology and the expansion of application scope, there is an increasing demand for high-precision linear sliding blocks that can handle larger-sized workpieces and have longer travel capabilities.

[0003] Existing linear sliding block designs typically rely on a single or multiple raceways to support and guide the movement of rollers. However, when the size of the sliding block increases and the inner raceway has a long travel, traditional designs face many challenges. For example, long travel increases the friction within the raceway, causing increased wear between the rollers and the raceway, thereby shortening the service life of the sliding block. In addition, large-sized sliding blocks are more prone to vibration and deviation during operation, affecting the overall precision and stability of the system. At the same time, long travel also increases the difficulty and cost of manufacturing, as it is very difficult to ensure consistency and uniformity throughout the entire travel range. SUMMARY

[0039] The application will be further described below in combination with the drawings:

[0040] Referring to the drawingsFigures 1 to 9 As shown: A linear slider device for guiding roller guide sleeves includes: a slider body 1 with inner raceway holes 100 on its left and right sides for roller movement, a pair of retainers 2 connected to the left and right sides of the slider body 1 respectively, and two end caps 3 fixed to the two end faces of the slider body. Each side of the slider body 1 has two inner raceway holes 100, and the two inner raceway holes 100 on the same side are arranged vertically and parallel to each other along the height of the slider body 1. Each end of the retainer 2 is provided with a positioning frame 200 that abuts against the end of the slider body 1. The positioning frame 200 has two internal circulation through holes 201 that match the internal raceway holes 100. The outer end of the positioning frame 200 has an internal circulation raceway section 202. The internal circulation raceway section 202 communicates with one of the internal circulation through holes 201. The internal circulation raceway sections 202 on both sides of the retainer 2 are arranged in opposite directions and are staggered. Each internal raceway hole 100 has two auxiliary strips 10 inserted into it, which fit together and form an internal raceway 101 in the middle. The internal raceway 101 is used to guide the flexible guide sleeve 11 with rollers installed to move along the length direction of the slider body 1 in the internal raceway 101.

[0041] The slider body 1 is the core part of the entire device. It has two inner raceway holes 100 on each of its left and right sides for the movement of the rollers. The two inner raceway holes 100 on the same side are arranged parallel to each other vertically along the height of the slider body 1. This double-layer raceway design increases the slider's load-bearing capacity and stability. A pair of retainers 2 are connected to the left and right sides of the slider body 1 respectively to support and fix the rollers and ensure their smooth operation within the inner raceways 101. Both ends of the retainers 2 are provided with connections to the ends of the slider body 1. The positioning frame 200, which is attached to the cage 2, ensures precise positioning between the cage 2 and the slider body 1 and provides necessary support. The positioning frame 200 has two internal circulation through holes 201 that match the inner raceway holes 100. These through holes allow the rollers to circulate within the inner raceway 101. In this embodiment, the outer end of the positioning frame 200 has an inner circulation raceway section 202, which communicates with one of the inner circulation through holes 201 to form a complete raceway circulation path. The cage 2 has two inner circulation through holes 201 on both sides. The inner circulation raceway section 202 is arranged in an alternating pattern with opposite orientations. This design allows the rollers to move smoothly in different directions, improving overall motion efficiency and stability. Each inner raceway hole 100 has two auxiliary strips 10 inserted into it, which fit together and form the inner raceway 101 in the middle. The design of the auxiliary strips 10 not only provides additional support, but also ensures the smooth operation of the rollers by forming a stable inner raceway 101. The inner raceway 101 is used to guide the flexible guide sleeve 11, on which the rollers are mounted, to move along the length of the slider body 1 in the inner raceway 101. The design of the flexible guide sleeve 11 increases the flexibility and adaptability of the rollers, enabling them to better cope with various working conditions. Two end caps 3 are fixed to the two end faces of the slider body 1, respectively, to close the two ends of the slider body 1, protect the internal structure, and prevent dust and other impurities from entering. The design of the end caps 3 also includes a detachable inner circulation end cap 300 for the flexible guide sleeve 11 to rotate cyclically. The detachable design facilitates maintenance and replacement, while ensuring the sealing and reliability of the entire device.

[0042] It is worth mentioning that the end cover 3 is equipped with an oil circuit system to facilitate the lubrication of the rollers in the inner raceway.

[0043] Preferably, such as Figure 3 , Figure 4 , Figure 7 , Figure 8 and Figure 9 As shown, an inner groove 102 is provided on the auxiliary strip 10 along its length direction. The inner grooves 102 of the two auxiliary strips 10 face the same direction. When the two auxiliary strips 10 are in contact with each other, the two inner grooves 102 surround each other to form an inner raceway 101.

[0044] Each auxiliary bar 10 has an inner groove 102 along its length. The inner grooves 102 of the two auxiliary bars 10 face the same direction. When the two auxiliary bars 10 are in contact with each other, their inner grooves 102 can be aligned and form a continuous channel. The main function of the inner groove 102 is to guide and support the movement of the roller inside it. Through the precise design of the inner groove 102, the movement of the roller in the slider body 1 can be ensured to be more stable and smooth. The inner groove 102 also provides the necessary guiding function, so that the roller can move in a straight line on a predetermined path, reducing the possibility of deviation and vibration, and increasing the load-bearing capacity and stability of the raceway. It is worth mentioning that the alignment and contact of the two inner grooves 102 is very critical. It must be ensured that there are no gaps or misalignments to avoid the roller getting stuck or worn during operation. The inner raceway 101 formed by the two inner grooves 102 is a closed and continuous channel in which the roller can move freely in a loop. This design not only improves the movement accuracy of the roller, but also enhances the durability and reliability of the entire slider device.

[0045] Furthermore, such as Figure 3 and Figure 7 As shown, guide grooves 103 are formed on the left and right sides of the inner raceway 101, and guide blocks 104 are provided at both ends of the flexible guide sleeve 11. The guide blocks 104 on both sides of the flexible guide sleeve 11 are slidably connected to the guide grooves 103 on both sides of the inner slide groove 102.

[0046] Guide grooves 103 are provided on the left and right sides of the inner raceway 101. These guide grooves 103 extend along the length of the inner raceway 101, ensuring continuous guidance throughout the entire stroke range. The guide grooves 103 are designed with high precision and surface finish to reduce friction and ensure smooth sliding of the guide blocks 104 within them. The flexible guide sleeve 11 is a key component for mounting the rollers, supporting and guiding the movement of the rollers in the inner raceway 101. Guide blocks 104 are provided at both ends of the flexible guide sleeve 11. These guide blocks 104 match the guide grooves 103 on both sides of the inner slide groove 102, ensuring precise positioning and stable movement of the flexible guide sleeve 11 in the inner raceway 101. The guide blocks 104 are located at both ends of the flexible guide sleeve 11, and their shape and size are precisely designed to ensure smooth sliding within the inner raceway 101. The tight fit of the guide groove 103 and the main function of the guide block 104 are to provide additional lateral support to prevent the flexible guide sleeve 11 from shifting or vibrating during operation. The sliding connection between the guide block 104 and the guide groove 103 ensures the smooth movement of the flexible guide sleeve 11 in the inner raceway 101, reducing unnecessary friction and wear. When the flexible guide sleeve 11 is installed in the inner raceway 101, the guide blocks 104 on both sides of it are slidably connected to the guide grooves 103 on both sides of the inner slide groove 102. This sliding connection not only provides the necessary lateral support, but also ensures the linear movement of the flexible guide sleeve 11 in the inner raceway 101, reducing the possibility of shifting and vibration, enabling the roller to perform high-precision linear movement on the predetermined path, and improving the stability of the entire slider device.

[0047] Furthermore, such as Figure 3 , Figure 7 and Figure 8 As shown, guide portions 105 are provided on the auxiliary strips 10 on both sides of the inner groove 102 along the length direction of the auxiliary strips 10. When the two auxiliary strips 10 are in contact with each other, the two guide portions 105 on the same side form guide grooves 103.

[0048] Guide portions 105 are provided on the auxiliary strips 10 on both sides of the inner groove 102 to further enhance the guiding accuracy and stability of the roller in the inner raceway 101. The guide portions 105 are located on both sides of the inner groove 102 of each auxiliary strip 10 and extend along the length of the auxiliary strip 10. Their shape and size are precisely designed to ensure that when the two auxiliary strips 10 are in contact with each other, the two guide portions 105 on the same side can be perfectly aligned and form a continuous guide groove 103. This design not only provides additional lateral support for the flexible guide sleeve 11, but also ensures its accurate positioning and stable movement in the inner raceway 101.

[0049] Preferably, such as Figure 4 , Figure 6 and Figure 7As shown, limiting grooves 106 are provided on both ends of the auxiliary strip 10. The inner circulation raceway 202 is provided with a first limiting part 203 facing the inner raceway hole 100 connected thereto. A pair of fitted auxiliary strips 10 are inserted from the other end of the inner raceway hole 100. One of the limiting grooves 106 at the insertion end of the two auxiliary strips 10 is engaged with the first limiting part 203, and the other limiting groove 106 is engaged with the end cap 3.

[0050] Limiting grooves 106 are provided at both ends of the auxiliary strip 10, and corresponding limiting parts are provided on the inner circulation raceway 202 and the end cap 3. The linear slider device of the present invention realizes the precise positioning and fixation of the auxiliary strip 10 in the inner raceway hole 100. When a pair of fitted auxiliary strips 10 are inserted from the other end of the inner raceway hole 100, the limiting groove 106 of one auxiliary strip 10 engages with the first limiting part 203 of the inner circulation raceway 202, and the limiting groove 106 of the other auxiliary strip 10 engages with the second limiting part 301 on the end cap 3. This design not only ensures the firm fixation of the auxiliary strip 10, but also facilitates maintenance and replacement.

[0051] Furthermore, such as Figure 4 , Figure 6 and Figure 7 As shown, a detachable inner circulation end cap 300 is provided on the inner side of the end cap 3. The inner circulation end cap 300, together with the inner sliding groove 102 and the inner circulation raceway 202, is used to allow the flexible guide sleeve 11 to rotate cyclically. A second limiting part 301 is provided on the inner circulation end cap 300. The second limiting part 301 is engaged with another limiting groove 106 at the insertion end of the two auxiliary strips 10.

[0052] The inner circulation end cap 300 is located inside the end cap 3 and is connected to the end cap 3 by insertion. The design of the inner circulation end cap 300 ensures that it can fit tightly against the end face of the slider body 1 and work in conjunction with the inner groove 102 and the inner circulation raceway 202. The main function of the inner circulation end cap 300 is to provide a closed and continuous circulation path for the flexible guide sleeve 11, so that the flexible guide sleeve 11 can smoothly circulate and rotate between the inner circulation end cap 300, the inner groove 102 and the inner circulation raceway 202. This design not only ensures the smooth operation of the flexible guide sleeve 11, but also improves the sealing and reliability of the entire slider device. The inner circulation end cap 300 is provided with a second limiting part 301, which is used for... The second limiting part 301 is designed to engage with another limiting groove 106 at the insertion end of the auxiliary strip 10. The design of the second limiting part 301 requires high precision to ensure that it can be accurately and tightly engaged with the limiting groove 106 on the auxiliary strip 10, thereby fixing the position of the auxiliary strip 10. When the two auxiliary strips 10 are attached to each other and inserted from the other end of the inner raceway hole 100, the limiting groove 106 of one auxiliary strip 10 engages with the first limiting part 203 of the inner circulation raceway part 202, and the limiting groove 106 of the other auxiliary strip 10 engages with the second limiting part 301 on the inner circulation end cover 300. This double engagement design ensures the accurate positioning and firm fixation of the auxiliary strip 10 in the inner raceway 101, preventing it from loosening or falling off during use.

[0053] Furthermore, such as Figure 4 , Figure 6 and Figure 7 As shown, the inner circulation end cap 300 is also provided with a third limiting part 302, which is engaged with the limiting groove 106 at the other end of the two auxiliary strips 10.

[0054] A third limiting part 302 is provided on the inner circulation end cap 300. The linear slider device of the present invention further enhances the fixation and positioning of the auxiliary strip 10 in the inner raceway 101. The third limiting part 302 is tightly engaged with the limiting groove 106 at the other end of the auxiliary strip 10. Together with the first limiting part 203 and the second limiting part 301, it achieves double fixation of both ends of the auxiliary strip 10. This multi-interlocking design not only improves the accurate positioning and firm fixation of the auxiliary strip 10, but also prevents it from loosening or falling off during use.

[0055] Preferably, the bottom of the auxiliary strip 10 is provided with a smooth surface 107, the smooth surface 107 is parallel to the bottom surface of the inner groove 102, and an arc-shaped portion 108 matching the inner raceway hole 100 is formed between one side of the smooth surface 107 and the guide portion 105 on the same side.

[0056] The bottom of the auxiliary bar 10 is provided with a smooth surface 107, and an arc-shaped portion 108 matching the inner raceway hole 100 is formed between one side of the smooth surface 107 and the guide portion 105 on the same side. This achieves higher stability and precise positioning. The smooth surface 107 is parallel to the bottom surface of the inner groove 102, providing a flat and smooth contact surface, reducing friction between the auxiliary bar 10 and the inner raceway hole 100, and improving operating efficiency and lifespan. The design of the arc-shaped portion 108 enhances the fit between the auxiliary bar 10 and the inner raceway hole 100, reduces the possibility of offset and vibration, ensures the stability and precise positioning of the auxiliary bar 10 in the inner raceway 101, and disperses the load, reducing local stress concentration.

[0057] Furthermore, such as Figure 4 , Figure 7 and Figure 9 As shown, a number of grooves 109 are evenly provided on the smooth surface 107, and the groove edges of adjacent grooves 109 form reinforcing ribs 110.

[0058] A plurality of grooves 109 are evenly provided on the smooth surface 107 of the auxiliary strip 10, and the groove edges of adjacent grooves 109 form reinforcing ribs 110. The linear slider device of the present invention achieves higher structural strength and stability. The design of the grooves 109 not only reduces the weight of the auxiliary strip 10, but also optimizes the use of materials and improves the lightweight design. The reinforcing ribs 110 enhance the structural strength of the auxiliary strip 10, prevent deformation or damage under load, and better distribute the load, reducing local stress concentration.

[0059] Preferably, such as Figure 4 and Figure 7 As shown, the positioning frame 200 is provided with two outer raceways 204 that match the inner circulation raceway section 202.

[0060] The positioning frame 200 is provided with two outer raceways 204 that match the inner circulating raceway 202. The outer raceways 204 provide an additional rolling path for the roller, allowing the roller to move smoothly in a circular motion between the inner and outer raceways 204.
