Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of mechanical transmission and guiding devices, and specifically relates to a separable rolling linear guide pair. Background Technology
[0002] In modern industrial manufacturing, linear guides are key components that enable sliding parts to perform high-precision linear reciprocating motion along a fixed direction. Their performance directly affects the working accuracy, rigidity, stability, and service life of the entire machine. Rolling linear guide pairs, due to their advantages such as low frictional resistance, high positioning accuracy, and fast dynamic response, have become core guiding elements in high-precision mechanical systems.
[0003] Traditional rolling linear guide pairs typically consist of a guide rail and a slider, where the slider achieves linear motion by rolling balls or rollers on the guide rail. The slider and guide rail are designed as a single unit, which often requires complete disassembly of the slider-guide rail connection mechanism during assembly or maintenance. This process is complex, time-consuming, and can easily cause the balls to scatter or be damaged, affecting subsequent installation accuracy and operational stability. Utility Model Content
[0004] The purpose of this invention is to address the separable rolling linear guide pair, which has the advantages of facilitating disassembly during operation and handling of dust accumulation on the track that cannot be cleaned.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a split type rolling linear guide pair, including a slide rail, a first slider and a second slider are slidably connected to the front and back of the slide rail, a first flat plate is rotatably connected to the top of the first slider, a slide groove is opened on the right side of the first flat plate, a second flat plate is rotatably connected to the top of the second slider, a cross platform is welded to the right side of the second flat plate, and the surface of the cross platform is engaged with the inner wall of the slide groove, and a left protrusion is bolted to the left side of the first slider and the second slider.
[0006] The above technical solution is adopted as follows: the first and second ball bearing groups on the inner walls of the first and second sliders are snapped onto both sides of the slide rail; the auxiliary slide table at the bottom of the first flat plate is snapped onto the inner wall at the bottom of the slide rail; the cross table on the right side of the second flat plate is slidably connected to the slide groove of the first flat plate; the cross table is snapped and fixed using a fixing block; a U-shaped block is snapped into the fixing block to increase stability; and dust and debris are cleaned during the operation of the first and second sliders by bolting on the left side protrusion.
[0007] The present invention is further configured such that a first set of ball bearings is installed on the inner wall of the first slider.
[0008] The above technical solution involves installing a first set of ball bearings on the inner wall, which is then snapped onto both sides of the slide rail during use to provide sliding force.
[0009] The present invention is further configured such that a second set of ball bearings is installed on the inner wall of the second slider.
[0010] The above technical solution involves installing a second set of ball bearings on the inner wall. During use, the first and second sets of ball bearings are engaged on both sides of the slide rail to provide sliding force.
[0011] The present invention is further configured such that an auxiliary slide is welded to the bottom of the first flat plate, and the surface of the auxiliary slide is slidably connected to the inner wall of the top of the slide rail.
[0012] The above technical solution involves welding an auxiliary slide table. After the first ball bearing on the inner wall of the first slider is engaged with the slide rail surface, the auxiliary slide table is then engaged with the top of the slide rail, providing assistance and stability during operation.
[0013] The present invention is further configured such that fixing blocks are engaged on the front and back of the cross platform.
[0014] The above technical solution is adopted: after the first plane plate and the second plane plate are snapped together, the cross platform is fixed with a fixing block to increase stability and prevent derailment and separation during operation.
[0015] The present invention is further configured such that U-shaped blocks are snapped into the front and back ends of the fixing block.
[0016] The above technical solution is adopted: by snapping on the U-shaped block, after snapping on the fixing block, the U-shaped block is snapped into the fixing block, and by stabilizing the first and second flat plates, separation is avoided during rapid operation.
[0017] The present invention is further configured such that a right-side protrusion is bolted to the right side of the first slider and the second slider.
[0018] The above technical solution is adopted because the surface of the slide rail is prone to dust and debris. By bolting the right-side protrusion, the first and second slides can be effectively cleaned during operation.
[0019] The present invention is further configured such that the inner walls of the left and right protrusions are provided with grooves.
[0020] The above technical solution involves cleaning debris and dust by pushing the left and right protrusions along with the first and second sliders, and the grooves prevent accumulation.
[0021] In summary, this utility model has the following beneficial effects:
[0022] 1. After the slide rail is engaged by the first slider and the first ball bearing assembly, the first flat plate is twisted and rotated to engage the auxiliary slide table on the top of the slide rail for fixation. After the second slider and the second ball bearing assembly are engaged on one side of the slide rail, the second flat plate is twisted and rotated to engage the slide groove with its cross table. The cross table is engaged with the fixing block, and the U-shaped block is engaged with the fixing block for fixation and installation, which is convenient for disassembly and installation.
[0023] 2. By bolting the left and right protrusions to both ends of the first and second flat plates, the left and right protrusions clean the dust and debris on the slide rail surface through the groove design during the pushing operation of the first and second sliders, thus preventing foreign objects from causing jamming in the operation of the first and second slider groups and affecting their use.

[0034] refer to Figure 3 An auxiliary slide 11 is welded to the bottom of the first flat plate 4, and the surface of the auxiliary slide 11 is slidably connected to the top inner wall of the slide rail 1. After the first ball bearing group 9 on the inner wall of the first slider 2 is engaged with the surface of the slide rail 1, the auxiliary slide 11 is engaged with the top of the slide rail 1, providing assistance and stability during operation.
[0035] refer to Figure 1 , Figure 2 , Figure 3 The cross table 7 has fixing blocks 12 snapped into its front and back sides.
