Description

Technical Field

[0001] The utility model belongs to the technical field of indexing devices, and in particular relates to a indexing device with high indexing accuracy. Background Art

[0002] In one clamping of the workpiece, after each surface is processed, the movable part of the fixture is rotated a certain angle or moved a certain distance together with the workpiece to change the position of the processed surface. The device that achieves the above-mentioned indexing requirements is called an indexing device.

Commonly used mechanical indexing plates use either the hive-tooth method or the worm gear method. Long-term drive rotation will inevitably lead to wear of the structural parts, resulting in reduced matching accuracy between the structural parts, making it impossible to deliver the workpiece to the preset position.

[0013] Compared with the prior art, the beneficial effects of the utility model are: the driving component drives the indexing plate to rotate, the light emitter and the light receiver are turned on, and the indexing plate drives the reflector to rotate synchronously. When the reflector rotates to a preset position, the light signal emitted by the light emitter is received by the light receiver through reflection by the reflector, proving that the mounting seat has rotated to the preset position at this time. The light receiver controls the driving component to stop driving the indexing plate to rotate through the control system, thereby achieving high-precision indexing positioning.
