Description

Technical Field

[0001] This utility model relates to the field of linear guide technology, specifically a combined linear guide. Background Technology

[0002] Modular linear guides are mechanical components primarily used in various automated equipment, precision machine tools, and other industrial applications to achieve high-precision, high-efficiency linear motion. They typically consist of guide rails, sliders, and ball or roller components, and can be modularly combined and adjusted according to different application requirements. Modular linear guides feature high precision, low friction, high rigidity, fast response, and good durability. Through modular design, they are easy to install and maintain, can withstand loads in different directions, and ensure stable equipment operation.

[0003] Existing modular linear guides require the guide rails to be installed first, followed by the slider. Since linear guides are often manufactured with fixed lengths, they may need to be spliced ​​during use. After splicing, errors in straightness and parallelism may occur between the two sections, requiring adjustment by operators. This adjustment involves directly moving the guide rails, which is cumbersome and hinders precision control. Utility Model Content

The rectangular plate 5 is fixedly mounted on the rear surface of the splicing track 4 and slidably inserted into the rectangular grooves 7 on the first guide rail 1. The two threaded rods 6 are rotatably mounted on the rear surface of the splicing track 4 and are threadedly connected to the interior of the first guide rail 1.

The two first adjusting bolts 9 are respectively threadedly connected to the interiors of the corresponding first guide rail 1 and the splicing track 4.

[0025] Furthermore, the splicing mechanism also includes two second adjusting bolts 10. The lower surfaces of the first guide rail 1 and the splicing track 4 are both provided with second circular grooves 11. The two second adjusting bolts 10 are respectively rotatably installed inside the two second circular grooves 11. The upper ends of the two second adjusting bolts 10 are rotatably inserted into the corresponding rectangular grooves 7. The two second adjusting bolts 10 are respectively threadedly connected to the corresponding first guide rail 1 and splicing track 4.

[0026] Furthermore, by pushing the rectangular plate 5 into the corresponding rectangular groove 7 and then rotating the two rotating rods 15 to rotate the threaded rod 6, the first guide rail 1, the splicing track 4, and the second guide rail 12 can be fixed, spliced, and disassembled. This allows workers to perform modular splicing between different guide rail sections and to make more convenient fine adjustments through the first adjusting bolt 9 and the second adjusting bolt 10 to compensate for deviations caused by manufacturing tolerances or installation errors, thereby improving the flexibility and convenience of the linear guide rail.

[0027] Furthermore, a second guide rail 12 is installed on the front side of the splicing track 4. Two identical threaded rods 6 are rotatably installed on the rear surface of the second guide rail 12. Both identical threaded rods 6 are connected to the internal threads of the splicing track 4. An identical rectangular plate 5 is fixedly installed on the rear surface of the second guide rail 12. The identical rectangular plate 5 is slidably inserted into the rectangular groove 7 on the splicing track 4.

[0028] Furthermore, a third circular groove 13 is provided on the upper surface of both the splicing track 4 and the second guide rail 12, and two mounting grooves 14 are provided inside both the splicing track 4 and the second guide rail 12, and the four threaded rods 6 rotate through the four mounting grooves 14 respectively.

The rotation of the rotating rod 15 drives the two second bevel gears 17 fixedly mounted on its outer surface to rotate, causing the first bevel gear 16 meshing with the second bevel gears 17 to rotate. The rotation of the first bevel gear 16 drives the two threaded rods 6 fixedly connected to it to rotate, so that the two threaded rods 6 enter the interior of the two threaded holes on the first guide rail 1, thereby tightening and fixing the first guide rail 1 and the splicing rail 4. After fixing, the first adjusting bolt 9 and the second adjusting bolt 10 on the first guide rail 1 can be rotated to move up and down inside the rectangular groove 7, thereby adjusting the rectangular plate 5 and the splicing track 4 fixedly connected to it.
