Description

Technical Field

[0001] This utility model relates to a slider. Background Technology

[0002] The slider is a key component in machine tool processing and other fields, serving as a linear guide for repetitive linear motion. In the existing technology, the slider includes a slider body, a reverse circulator, and an oil scraper. Generally, the reverse circulator is first installed on both sides of the slider body along the axis, and then the oil scraper is installed on both sides of the reverse circulator. Finally, it is axially fixed by relatively long bolts.

[0003] In actual production, because the reverse circulator and the slider body are matched through a planar mating structure, the reverse circulator is prone to displacement during assembly. This leads to misalignment between the rolling groove inside the slider body and the arc-shaped turning groove on the directional circulator, making the product unqualified. When it enters the market, it will greatly affect the accuracy of the slider in linear motion and its service life will also be greatly affected, causing incalculable losses to users. Summary of the Invention

[0004] The purpose of this invention is to provide a slider with a high assembly qualification rate and the ability to effectively improve the efficiency of sound production.

[0005] To achieve the above objectives, this utility model employs a slider, which includes...

[0006] The slider body has an axially extending groove for matching the guide rail, so that the slider can achieve linear movement on the guide rail. In this utility model, guide walls are formed on both sides of the groove, and a first and a second axially extending groove for the rolling of the ball are formed on each guide wall. The first and the second grooves are parallel to each other on the same horizontal plane.

[0007] Reverse circulator: It is used to install at both ends of the slider body along the axial direction. A boss is formed on the side facing the slider body. A groove is formed on the slider body at the position corresponding to the boss. The groove is adapted to the boss. An arc-shaped turning groove is formed on the boss. The two ends of the arc-shaped turning groove are respectively matched with the first rolling groove and the second rolling groove, so that the first rolling groove and the second rolling groove form a closed-loop link of an elongated oval track structure through the arc-shaped turning grooves at both ends. Furthermore, the balls in the closed-loop link achieve infinite cyclic rolling, so that the slider forms a linear sliding motion on the guide rail.

[0008] Oil scraper: Installed at both ends of the reverse circulator, it serves the functions of dust prevention and providing lubrication passage.

[0009] As a further feature of this invention, an arc-shaped protrusion is formed on the slider body at a position corresponding to the arc-shaped turning groove. A transverse positioning groove is formed between the arc-shaped protrusion and the slider body. A transverse positioning rib adapted to the transverse positioning groove is formed on the protrusion. An axially extending longitudinal positioning rib is also formed on the protrusion, and a longitudinal positioning groove adapted to the longitudinal positioning rib is formed at the bottom of the groove. This positioning structure effectively ensures the matching accuracy between the arc-shaped turning groove and the first and second rolling grooves, preventing displacement beyond the error range between the reverse circulator and the slider body. As a further improvement of this invention, the inner edge of the longitudinal positioning rib matches the arc-shaped edge of the arc-shaped turning groove.

[0010] As a further feature of this invention, the reverse circulator has at least two axially extending first positioning posts on the side facing the slider body, and the slider body has a first positioning hole adapted to the first positioning posts. This structure further ensures the assembly accuracy between the reverse circulator and the slider body, and further improves the stability, reliability and pass rate of the product.

[0011] As a further feature of this invention, in order to improve the assembly accuracy between the oil scraper and the reverse circulator, at least two axially extending second positioning posts are provided on the reverse circulator on the side facing the oil scraper, and the oil scraper is provided with second positioning holes adapted to the second positioning posts.

[0012] Through the improvement of the existing technology by the above-mentioned technology, the slider of this utility model achieves the following beneficial effects: due to the direct use of the matching structure of boss and groove, combined with the positioning of the first positioning post and the first positioning groove, the product is more easy to assemble, which greatly improves the assembly efficiency and the qualification rate of the finished product.

[0018] Figures 1-5 As shown, this embodiment uses a slider. Figure 1 The diagram clearly shows that it includes a slider body 1, a reverse circulator 2, and an oil scraper 3, combined with... Figure 2 , Figure 3 and Figure 5 It is known that the slider body 1 has an axially extending groove 10 for matching the guide rail, so that the slider can achieve linear movement on the guide rail. In this embodiment, guide walls 11 are formed on both sides of the groove 10. Each guide wall 11 is formed with an axially extending first groove 110 and a second groove 111 for rolling of balls. The first groove 110 and the second groove 111 are distributed in parallel on the same horizontal plane.

[0019] Figure 2 , Figure 3 Combination Figure 4 It is understood that the reverse circulation device 2 is used to be installed at both ends of the slider body 1 along the axial direction. A boss 20 is formed on the side facing the slider body. A groove 112 is formed on the slider body 1 at the position corresponding to the boss 20. The groove 112 is adapted to the boss 20. An arc-shaped turning groove 200 is formed on the boss 20. The two ends of the arc-shaped turning groove 200 are respectively matched with the first rolling groove 110 and the second rolling groove 111. Thus, the first rolling groove 110 and the second rolling groove 111 form a closed-loop link of an elongated oval track structure through the arc-shaped turning groove 200 set at both ends of the axial direction. Furthermore, the balls in the closed-loop link achieve infinite cyclic rolling, so that the slider forms a linear sliding motion on the guide rail.

[0020] Figure 1 , Figure 2 and Figure 3 As can be seen from the diagram, the oil scraper 3 is installed at both ends of the reverse circulator 2, and it has the functions of dust prevention and providing lubrication passage.

[0021] Figure 2 , Figure 3 and Figure 5 As shown in this embodiment, an arc-shaped protrusion 113 is formed on the slider body 1 at a position corresponding to the arc-shaped turning groove 200. A transverse positioning groove 114 is formed between the arc-shaped protrusion 113 and the slider body 1. A transverse positioning rib 201 adapted to the transverse positioning groove 114 is formed on the boss 20. Figure 4Further, the boss 20 has an axially extending longitudinal positioning rib 202, and the bottom of the groove 200 forms a longitudinal positioning groove 115 that matches the longitudinal positioning rib 202. The above-mentioned positioning structure in this embodiment can effectively ensure the matching accuracy between the arc-shaped turning groove 200 and the first rolling groove 110 and the second rolling groove 111. During the assembly process, it can avoid the phenomenon of displacement beyond the error range between the reverse circulator 2 and the slider body 1. In this embodiment, preferably, the inner edge of the longitudinal positioning rib 202 matches the arc-shaped edge of the arc-shaped turning groove 200, so that the inner surface of the longitudinal positioning rib 202 also becomes part of the ball raceway (i.e., closed-loop link).

[0022] Figure 2 , Figure 3 As shown in this embodiment, the reverse circulator 2 has at least two axially extending first positioning posts 21 on the side facing the slider body 1, and the slider body 1 has a first positioning hole 12 adapted to the first positioning posts 21. This structure in this embodiment further ensures the assembly accuracy between the reverse circulator 2 and the slider body 1, and the stability, reliability and pass rate of the product are further improved.

[0023] Figure 2 and Figure 3 Furthermore, in this embodiment, in order to improve the assembly accuracy between the scraper blade 3 and the reverse circulator 2, at least two axially extending second positioning posts 22 are provided on the reverse circulator 2 on the side facing the scraper blade 3, and the scraper blade 3 is provided with second positioning holes 30 that are adapted to the second positioning posts 22.
