[0038] To enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this specification, and not all embodiments. Based on the embodiments in this specification, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this specification.

[0039] To address the problem of difficulty in adjusting the length of existing linear guides, an embodiment of the first aspect of this application provides a modular combined linear track device, comprising a platform, a base, and a guide rail. The base is disposed on the platform, and the guide rail is disposed on the base. The platform supports both the base and the guide rail, while the base supports the guide rail and provides a flat mounting surface for the guide rail, allowing it to be stably mounted on the mounting surface, improving the guide rail's accuracy and reducing its vibration.

[0040] like Figures 1 to 4 As shown, the platform includes one platform module 10 or multiple platform modules 10 sequentially assembled along its length. That is, the platform is a modular platform, which can be assembled from platform modules 10. The structures and dimensions of each platform module 10 can be identical. Of course, depending on actual needs, the structures and dimensions of each platform module 10 can also be different.

[0041] like Figures 1 to 4 As shown, the base includes a single base module 20 or multiple base modules 20 sequentially assembled along its length. That is, the base is modular, and it can be assembled from base modules 20. The structures and dimensions of each base module 20 can be identical. Of course, depending on actual needs, the structures and dimensions of each base module 20 can also be different.

[0042] like Figures 1 to 4 As shown, the guide rail includes one guide rail module 30 or multiple guide rail modules 30 sequentially spliced ​​along its length. That is, the guide rail is a modular guide rail, which can be assembled from guide rail modules 30. The structures and dimensions of each guide rail module 30 can be identical. Of course, depending on actual needs, the structures and dimensions of each guide rail module 30 can also be different.

[0043] exist Figures 1 to 4 In the example, each platform module 10 has the same structure and size. The platform module 10 includes a rectangular main structure 101, a plurality of rollers 102 located at the bottom of the main structure 101, and a plurality of support legs 103 located at the bottom of the main structure 101.

[0044] exist Figures 1 to 4 In the example, the various base modules 20 have the same structure but not exactly the same dimensions. Specifically, the base modules 20 have different lengths but the same width and height. Each base module 20 includes a plate-shaped body 201 and multiple bolts 202. The body 201 has an upper surface 2011 and a lower surface 2012. The upper surface 2011, especially the middle portion, is a flat surface 2013 with high flatness. The guide rail is placed on this flat surface. Multiple bolts 202 are installed on the lower surface 2012 of the body 201. The base module 20 contacts the platform module 10 through these bolts 202. Each bolt 202 includes a bolt rod and a nut. The height of the bolt 202 can be adjusted by rotating the nut, thereby adjusting the flatness of the upper surface of the base module 20.

[0045] exist Figures 1 to 4 In the example, the various guide rail modules 30 have the same structure, but their dimensions are not exactly the same. Specifically, the lengths of the guide rail modules 30 are different, while their widths and heights are the same. The bottom surface of the guide rail contacts the upper surface 2011 of the base module 20. The two sides of the guide rail are respectively provided with sliding grooves 301 extending along the length direction to cooperate with the sliding body 50, so that the sliding body 50 can move smoothly in a straight line along the upper surface 2011 of the guide rail and the sliding grooves 301 on both sides.

[0046] In some embodiments, to facilitate module combination, a platform module, three types of base modules, and nine types of guide rail modules are provided.

[0047] like Figures 5 to 21 As shown, a platform module 10 has a length of n. When assembling a linear track device, one or more platform modules 10 can be used to form a platform. For example, when a linear track device with a length of 3n is required, three platform modules 10 can be quickly assembled to obtain a linear track device with the required length.

[0048] like Figures 5 to 21 As shown, the three base modules are a first base module 21 with a length of 1n-t, a second base module 22 with a length of 2n-t, and a third base module 23 with a length of 3n-t, where t is the sum of the gaps between the end faces of the base and the end faces of the platform. When assembling the linear track device, one or more base modules can be selected from the group consisting of the first base module 21, the second base module 22, and the third base module 23, such that the gaps between the end faces of the entire base and the end faces of the entire platform are t / 2 respectively. For example, only the first base module 21 can be selected, one or more first base modules 21 can be used, or only the second base module 22 and the third base module 23 can be selected, and the number of the second base module 22 and the third base module 23 can be one or more.

When assembling the linear track device, one or more of the following components can be selected from the group consisting of the first guide rail module 31, the second guide rail module 32, the third guide rail module 33, the fourth guide rail module 34, the fifth guide rail module 35, the sixth guide rail module 36, the seventh guide rail module 37, the eighth guide rail module 38, and the ninth guide rail module 39, such that the gaps between the end faces of both ends of the entire guide rail and the end faces of both ends of the entire platform are m respectively. For example, only the second guide rail module 32 can be selected, and one or more first guide rail modules 31 can be used; or only the eighth guide rail module 38 and the ninth guide rail module 39 can be selected, and the number of the eighth guide rail module 38 and the ninth guide rail module 39 can be one or more.

[0050] The platform module 10, base module 20 and guide rail module 30 provided in this embodiment are related in length and fully consider the gap parameters between the platform, base and guide rail, so as to facilitate quick splicing to obtain a linear track device of the required length without adjusting the length of the linear motion track by means of cutting.

[0051] When assembling the linear track device, the end faces of any two adjacent platform modules are made to fit together, and there is a gap of length t between any two adjacent base modules. The gaps between the end faces of the two ends of the base and the end faces of the two ends of the platform are 2 / t respectively. The end faces of any two adjacent guide rail modules are made to fit together, and the gaps between the end faces of the two ends of the guide rail and the end faces of the two ends of the platform are m respectively.
