[0035] See also Figure 1-8 The guide rail assembly 100 of the embodiment of the present application is suitable for a magnetic suspension conveyor line, and the guide rail assembly 100 includes two guide rails 1 and a slider (not shown), the slider is installed on the guide rails 1, and can slide between the two guide rails 1. More specifically, as follows:
[0036] like Figure 1-7 As shown, the guide rail 1 of the embodiment of the present application has a top surface 11, two side surfaces 12, a bottom surface 13 and two end surfaces 14. The top surface 11 and the two side surfaces 12 are in contact with the slider, the bottom surface 13 and the top surface 11 are arranged back to back, the top surface 11 and the two side surfaces 12 extend along the guiding direction 9 (parallel to the direction indicated by the arrow L) of the guide rail 1, the two side surfaces 12 are parallel to each other and are respectively arranged on both sides of the top surface 11, the two side surfaces 12 are respectively perpendicular to the top surface 11, and the two side surfaces 12 are respectively provided with a slide groove 12a, and the two slide grooves 12a extend along the guiding direction of the guide rail 1, and each divides the corresponding side surface 12 into a first group of surfaces 121 close to the top surface 11 and a second group of surfaces 122 away from the top surface 11, and the two second groups of surfaces 122 are configured as the reference surface of the guide rail 1. One end of the guide rail 1 has a transition docking section 1a, and the top surface 11 is provided with a top surface chamfer 11a in the transition docking section 1a. The two first groups of surfaces 121 are respectively provided with a side chamfer 121a, so that when the slider slides away from the transition docking section 1a, the shell greatly reduces the bounce and ensures the smooth sliding of the slider.
[0037] It is understandable that, according to actual conditions, in other embodiments, a slide groove 12a may be provided on only one side surface. Correspondingly, the slide groove extends along the guiding direction of the guide rail 1, and each divides a corresponding side surface 12 into a first group of surfaces close to the top surface 11 and a second group of surfaces away from the top surface 11. A second group of surfaces divided out is used as a reference surface of the slider, and a first group of surfaces divided out is also provided with a side chamfer in the transition section, which can also achieve the above-mentioned effect, so it is not limited to this.
[0038] like Figure 8 As shown, the guide rail assembly 100 of the embodiment of the present application further includes a ball (not shown), which is arranged between the slider and the guide rail 1 to reduce the friction between the slider and the guide rail 1. Specifically, Figure 1-7 As shown, any first group of faces 121 is provided with a first ball groove 16 on one side close to the corresponding slide groove 12a, and the top surface 11 is provided with a second ball groove 17, and the balls are respectively arranged in the first ball groove 16 and the second ball groove 17, and the first ball groove 16 and the second ball groove 17 are extended along the guide direction of the guide rail 1 to penetrate the guide rail 1, thereby providing a limit and guide for the balls, and ensuring a stable support and smooth sliding between the slider and the guide rail 1, but not limited to this; in addition, preferably, two second ball grooves 17 are arranged in parallel and spaced apart, of course, according to actual conditions, in other embodiments, one second ball groove 17 can be arranged, or three, four, five, etc., of the second ball grooves 17 can be arranged in parallel and spaced apart, so it is not limited to this. Similarly, in other embodiments, two, three, four, etc., etc., can also be arranged on one side, not limited to the attached drawings.
[0039] Without being limited to the drawings, in the guide rail assembly 100 of the embodiment of the present application, the slider can be slidably engaged in the slide groove 12a.
[0040] For example, the angle α of the top chamfer 11a relative to the top surface 11 is 1.5°-2.5°, which can greatly reduce the bounce of the slider. Figure 4 As shown, the angle α of the top chamfer 11a relative to the top surface 11 is 2° to further reduce the bounce of the slider, but the present invention is not limited thereto.
[0041] For example, the angle β of the side chamfer 121a relative to the side 12 is 1.5°-2.5°, which can greatly reduce the bounce of the slider. Figure 7 As shown, the angle β of the side chamfer 121a relative to the side 12 is 2° to further reduce the bounce of the slider, but the present invention is not limited thereto. It is understandable that in other embodiments, the angle β of the side chamfer 121a relative to the side 12 can also be 1.5°, 1.8°, 2.2°, 2.5°, etc., which are different degrees within the range of 1.5°-2.5°, so the present invention is limited thereto.
[0042] For example, the maximum depth H of the top chamfer 11a relative to the top surface 11 is 0.05mm-0.15mm deeper than the depth of the corresponding second ball groove 17 relative to the top surface 11, which can greatly reduce the bounce of the slider. Figure 5 As shown, the maximum depth H of the top chamfer 11a relative to the top surface 11 is 0.1mm deeper than the depth of the second ball groove 17 relative to the top surface 11, so that the detected runout value of the transition of a single slider can be reduced to less than 0.001mm, and the runout value detected on both sides of the transition of the four sets of slider assembly structure is less than 0.01mm, which is more suitable for high-speed and high-precision occasions, but not limited to this. It can be understood that in other embodiments, the maximum depth H of the top chamfer 11a relative to the top surface 11 is 0.05mm, 0.07mm, 0.12mm, 0.15mm, etc., which are different depths within 0.05mm-0.15mm than the depth of the corresponding first ball groove 16 relative to the top surface 11, so this is limited.
[0043] like Figure 8 As shown, in the guide rail assembly 100 of the embodiment of the present application, at least two guide rails 1 are provided, and the end surfaces of two adjacent guide rails 1 are arranged in an aligned manner so that the slider can slide between the two guide rails 1. It is understandable that in other embodiments, the guide rails 1 may also be provided in different numbers such as three, four, and five, and correspondingly, the end surfaces of two adjacent guide rails 1 are arranged in an aligned manner so that the slider can slide between any two adjacent guide rails 1; of course, according to actual conditions, only one guide rail 1 may be provided, so it is not limited thereto.
[0044] Not limited to the attached drawings, the distance between two adjacent guide rails 1 is less than or equal to 1 / 3 of the diameter of the ball, which can greatly reduce the bounce of the slider. Figure 8 As shown, in the guide rail assembly 100 of the embodiment of the present application, the distance between two adjacent guide rails 1 is 1 mm, and the diameter of the ball is 3 mm, so as to further reduce the vibration, but it is not limited to this. It is understandable that in other embodiments, the distance between two adjacent guide rails 1 is 0.5, and the diameter of the ball is 1.5 mm; or, the distance between two adjacent guide rails 1 is 1.5, and the diameter of the ball is 4.5 mm, so it is not limited to this.
[0045] It should be noted that, in the drawings, the direction pointed by the arrow L is the guiding direction of the guide rail 1 , but the present invention is not limited thereto.
[0046] Compared with the prior art, the guide rail 1 of the embodiment of the present application has a top surface 11 and two side surfaces 12 that are connected to the slider, the top surface 11 and the two side surfaces 12 extend along the guide direction of the guide rail 1, the two side surfaces 12 are parallel to each other and are respectively arranged on both sides of the top surface 11, the two side surfaces 12 are respectively perpendicular to the top surface 11, at least one side surface 12 is provided with a slide groove 12a, the slide grooves 12a extend along the guide direction of the guide rail 1, and divide the corresponding side surface 12 into a first group of surfaces 1 close to the top surface 11. 21 and a second group of faces 122 away from the top surface 11, the second group of faces 122 are configured as the reference surface of the guide rail 1, one end of the guide rail 1 has a transition docking section 1a, the top surface 11 is provided with a top surface chamfer 11a in the transition docking section 1a, and the first group of faces 121 is provided with a side chamfer 121a in the transition docking section 1a, so that when the slider passes through the transition docking section 1a of the guide rail 1 of the embodiment of the present application and slides away, the bounce of the slider can be greatly reduced, so that the guide rail of the embodiment of the present application is suitable for high-precision application scenarios. In addition, since the guide rail assembly 100 of the embodiment of the present application includes a slider and a guide rail 1, the slider can be slidably engaged in the slide groove 12a. By the same token, it can be known that the guide rail assembly of the embodiment of the present application is suitable for high-precision application scenarios.
[0047] The above disclosure is only a preferred example of the present application, and its role is to facilitate the technical personnel in this field to understand and implement it, but it cannot be used to limit the scope of rights of the present application. Therefore, equivalent changes made within the scope recorded in this application still fall within the scope covered by this application.
