[0002] Machine tool indexing is a device used to rotate and position workpieces or tools on machine tools. It is one of the key equipment for precision machining. Since the indexing of machine tools is rotating, there is a certain gap. However, if the gap is large, the overall load will be small. If the gap is small, it is easy to cause wear between the indexing plate and the base, resulting in a short service life of the indexing plate. Summary of the invention

[0005] According to the indexing suitable for precision surface treatment machine tools of the embodiment of the present invention, a first locking mechanism is provided, and the second oil cylinder drives the first holding piece, so that the first locking groove and the first locking rod are clamped together to fix the dividing plate, thereby preventing the dividing plate from shaking, thus forming the first fixation of the dividing plate; a second locking mechanism is provided, and the locking plate is fixed by the second locking mechanism, so that the connection between the locking plate and the base is more stable, that is, the supporting force of the dividing plate will be greater, the overall supporting force will be greater, and the load will be greater, thus forming the second fixation of the dividing plate; by fixing the dividing plate twice, the overall load can be guaranteed even when the gap is large.

[0006] According to the indexing device applicable to a precision surface treatment machine tool according to the embodiment of the present invention, the second locking mechanism evenly locks the locking disk.

[0007] According to the indexing method for a precision surface treatment machine tool according to an embodiment of the present invention, the second locking mechanism includes A third oil cylinder, the third oil cylinder comprising an oil cylinder seat; A second pressing member, wherein a pressing portion is provided at a first end of the second pressing member, a middle portion of the second pressing member is hinged to a cylinder seat, a second end of the second pressing member is connected to an output shaft of a third cylinder, and the second end of the second pressing member is lifted up by the output shaft of the third cylinder; The locking disk and the indexing disk are fixedly connected through a concentric shaft and form a second locking groove, and the diameter of the locking disk is smaller than the diameter of the indexing disk.

The locking plate 600 is pressed by multiple second locking mechanisms 500, so that zero clearance can be achieved between the locking plate 600 and the base 700, which better supports and fixes the indexing plate 100. The locking plate 600 is fixedly connected to the indexing plate 100 through a concentric axis and forms a second locking groove 610. The diameter of the locking plate 600 is smaller than the diameter of the indexing plate, and the holding portion 521 extends into The second locking groove 610 drives the second pressing member 520 through the third oil cylinder 510 to push the second end of the second pressing member 520 upward, so that the pressing portion 521 moves downward to press the locking plate 600, thereby realizing the second fixation of the dividing plate 100, and a plurality of second locking mechanisms 500 are evenly arranged. The second locking mechanism 500 evenly presses the locking plate 600 to ensure that the locking plate 600 and the rotating shaft 200 are evenly stressed, and zero gap between the locking plate 600 and the base 700 can be achieved, that is, the locking plate 600 and the base 700 form a whole, the overall structure is more stable, the supporting force is stronger, and the load is greater.
