[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0017] Example 1

[0018] like Figures 1 to 3 As shown, a specific embodiment of a guide rail adjustment device for a three-dimensional coordinate measuring machine described in the utility model comprises: a moving seat 4 installed on an assembly plate 1 of the three-dimensional coordinate measuring machine, a guide rail body 14 is installed above the moving seat 4, a side adjustment block 2 is fixedly installed on the assembly plate 1, the side adjustment block 2 is arranged on the left and right sides of the moving seat 4, an adjusting bolt 3 is threadedly installed at the center position of the side adjustment block 2, one end of the adjusting bolt 3 abuts against the side of the moving seat 4, the adjusting bolt 3 is used to adjust the horizontal position of the moving seat 4, a transverse groove 5 and a threaded adjustment hole 7 are opened on the moving seat 4, the threaded adjustment hole 7 is opened in the middle position of the moving seat 4, and three equidistantly arranged transversely A threaded sleeve 12 is installed in the inner thread of the threaded adjustment hole 7, and an adjusting disc 8 is integrally formed on the top of the threaded sleeve 12. The threaded sleeve 12 and the adjusting disc 8 are used to level the height of the guide rail body 14; the transverse groove 5 is symmetrically arranged on both sides of the movable seat 4, and a first fixing bolt 6 is installed in the transverse groove 5. The first fixing bolt 6 is used to fix the movable seat 4. A bottom plate 13 is provided at the bottom of the assembly plate 1, and a second fixing bolt 11 is installed on the bottom plate 13. The second fixing bolt 11 passes through the bottom plate 13, the assembly plate 1, the threaded adjustment hole 7 and the threaded sleeve 12 in sequence and is threadedly connected to the guide rail body 14. The second fixing bolt 11 is used to fix the whole after the adjustment is completed.

[0019] A conical groove is formed on the top of the adjusting disc 8, and a conical pad 10 for supporting the guide rail body 14 is installed in the conical groove. The conical pad 10 is used to provide more stable support for the guide rail.

[0020] The three-dimensional coordinate measuring machine needs to be installed with two parallel guide rails. Two guide rail adjustment devices are assembled into a group to assemble one guide rail. One of the guide rail adjustment devices is installed with two adjustment discs 8 and two second fixing bolts 11, and the other guide rail adjustment device is installed with one adjustment disc 8 and a second fixing bolt 11. When adjusting, only the end with fewer components can be adjusted. This installation method is convenient for adjusting the horizontal angle of the guide rail, so that the two guide rails on the three-dimensional coordinate measuring machine are parallel, and at the same time, they can also remain firm and stable.

[0021] The first fixing bolt 6 and the second fixing bolt 11 are provided with elastic washers and gaskets.

[0023] Working principle of the utility model: The utility model can perform horizontal adjustment and height adjustment: by screwing the adjusting bolt 3, one end of the bolt will push the moving seat 4 to make it move horizontally on the assembly plate 1, and this movement will change the horizontal position of the guide rail body 14 until the required horizontality is reached; by rotating the adjusting disk 8 in cooperation with the crescent wrench and the tooth hole 9, the threaded sleeve 12 will be driven to move up and down. Since the threaded sleeve 12 is indirectly connected to the guide rail body 14, this movement will change the height of the guide rail body 14. By accurately controlling the rotation angle and force, the height of the guide rail body 14 can be fine-tuned until the required horizontality and stability are reached, and finally the first fixing bolt 6 and the second fixing bolt 11 are tightened to fix the whole.

[0024] The entire adjustment process is simple and easy, with high accuracy and stability, and is suitable for various high-precision three-dimensional coordinate measuring machines.
