[0028] In order to solve the problem that the length of the linear guide rail in the prior art is difficult to adjust, the embodiment of the first aspect of the present application provides a modular combined linear rail device, which includes a platform, a base and a guide rail. The base is arranged on the platform, and the guide rail is arranged on the base. The platform plays a role of supporting the base and the guide rail, and the base plays a role of supporting the guide rail and providing a mounting plane with high flatness for the guide rail, so that the guide rail can be stably installed on the mounting plane, the accuracy of the guide rail is improved, and the vibration of the guide rail is reduced.

[0029] like Figures 1 to 4 As shown, the platform includes a platform module 10 or a plurality of platform modules 10 sequentially spliced ​​along the length direction. That is, the platform is a modular platform, which can be spliced ​​by the platform modules 10. The structures and sizes of the platform modules 10 can be the same. Of course, according to actual needs, the structures and sizes of the platform modules 10 can also be different.

That is, the base is a modular base, which can be spliced ​​by the base modules 20. The structures and sizes of the base modules 20 can be the same. Of course, according to actual needs, the structures and sizes of the base modules 20 can also be different.

[0031] like Figures 1 to 4 As shown, the guide rail includes a guide rail module 30 or a plurality of guide rail modules 30 sequentially spliced ​​along the length direction. That is, the guide rail is a modular guide rail, which can be spliced ​​by the guide rail modules 30. The structures of the guide rail modules 30 can be the same, and the sizes can also be the same. Of course, according to actual needs, the structures of the guide rail modules 30 can also be different, and the sizes can also be different.

[0032] exist Figures 1 to 4 In the example, each platform module 10 has the same structure and size. The platform module 10 includes a square frame-shaped main structure 101, a plurality of rollers 102 disposed at the bottom of the main structure 101, and a plurality of support legs 103 disposed at the bottom of the main structure 101.

[0033] exist Figures 1 to 4In the example, the structures of the base modules 20 are the same, but the sizes are not exactly the same. Specifically, the base modules 20 have different lengths, but the widths and heights are the same. The base module 20 includes a plate-shaped body 201 and a plurality of bolts 202. The body 201 has an upper surface 2011 and a lower surface 2012. The upper surface 2011 of the body 201, especially the middle part of the upper surface 2011, is a plane 2013 with high flatness. The guide rail is placed on the plane. The plurality of bolts 202 are installed on the lower surface 2012 of the body 201. The base module 20 contacts the platform module 10 through the plurality of bolts 202. The bolts 202 include bolt rods and nuts. The height of the bolts 202 can be adjusted by rotating the nuts, thereby adjusting the flatness of the upper surface of the base module 20.

[0034] exist Figures 1 to 4 In the example, the structures of the guide rail modules 30 are the same, but the sizes are not exactly the same. Specifically, the guide rail modules 30 have different lengths, but the widths and heights are the same. The bottom surface of the guide rail contacts the upper surface 2011 of the base module 20, and the two sides of the guide rail are respectively provided with slide grooves 301 extending along the length direction to cooperate with the sliding body 50, so that the sliding body 50 can move smoothly and linearly along the upper surface 2011 of the guide rail and the slide grooves 301 on both sides.

[0036] like Figures 5 to 21 As shown, a platform module 10 is a platform module 10 of length n. When assembling a linear track device, one or more platform modules 10 can be used to form a platform.
