Examples

As shown in fig. 1 and 2, an ultra-precise indexer for an optical profile grinder includes a base 10, a brushless motor 20, and a top base 40; the brushless motor 20 is arranged on the base 10, an output shaft of the brushless motor 20 is arranged upwards, the top seat 40 is arranged on the output shaft of the brushless motor 20 through the reduction gear box 30, a magnet 42 for adsorbing and fixing a workpiece is arranged at the top of the top seat 40, and a threaded hole 43 for installing and fixing the workpiece is arranged at the center of the top seat 40; the brushless motor 20 is connected with a pulse signal generator.

In one embodiment, two grooves 41 are symmetrically formed in the top of the top base 40 around the central axis, and bar-shaped magnets 42 are respectively mounted in the two grooves 41.

In one embodiment, the top of the top seat 40 is symmetrically provided with two positioning holes 44 centered on the threaded hole 43.

In one embodiment, a ring of L ED lamps 50 is disposed around the top base 40.

The invention sends pulse signals to the brushless motor 20 through the pulse signal generator to control the work of the brushless motor 20, the brushless motor 20 drives the top to rotate after passing through the reduction gear box 30 with large reduction ratio, thereby driving the workpiece fixed on the top seat 40 to rotate, and the workpiece can be fixed through bolts or directly and conveniently adsorbed on the top seat 40 by the magnet 42. The rotating angle of the output shaft of the brushless motor 20 driven by a single pulse and the reduction ratio of the reduction gear box 30 can be calculated, so that the rotating angle of the top seat 40 driven by the brushless motor 20 under the single pulse can be calculated, and the indexing positioning of the circular workpiece can be realized by controlling the pulse number output by the pulse signal generator to the brushless motor 20 according to the rotating angle of the workpiece.

The positioning hole 44 is used for positioning a circular workpiece while preventing the workpiece from rotating when the workpiece is mounted by a bolt, and the L ED lamp 50 can provide sufficient illumination conditions for the optical curve grinding machine.

The above-mentioned embodiments only express the specific embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
