Clamp driving mechanism special for ornament machining equipment

Abstract

The invention relates to a clamp driving mechanism special for ornament machining equipment. The clamp driving mechanism comprises a rotation unit, an ornament surface parting unit and an equipment body, wherein left and right ends of the rotation unit are fixed to the equipment body respectively; the left end of the ornament surface parting unit is supported inside the left end of the rotation unit, and the right end of the ornament surface parting unit is fixed to the middle of the rotation unit; two ends of a clamp base of the rotation unit are connected with a support shaft and a connecting shaft; the support shaft is supported on a left bearing pedestal by a left angular contact ball bearing combination piece; the connecting shaft is supported on a right bearing pedestal by a right angular contact ball bearing combination piece; a motor support and a right adjusting cushion are fixed to the right bearing pedestal; a contracting brake motor is connected with the connecting shaft; according to the ornament surface parting unit, a motor with a key is fixed to the support shaft and is connected with a transmission shaft; a clamp is fixed to the clamp base; and the transmission shaft is fixed in the support shaft and is connected with a worm of a clamp power input shaft. By the clamp driving mechanism, the quality of ornaments is improved effectively, multiple kinds of ornaments can be machined on one equipment, resources are saved, and noise pollution is reduced.

Description

[0001] technical field [0002] The invention belongs to the field of jewelry processing machinery, and relates to a special clamp driving mechanism for jewelry processing equipment. Background technique [0003] At present, there are mainly two types of flipping fixtures used in domestic jewelry processing equipment: one is that the cylinder on the processing equipment directly pulls the fixture to turn the fixture over; the other is that the eccentric gear is driven by the motor, and the eccentric gear drives the fixture. on the gear to flip the jig over. These two overturning forms make the angle of fixture overturning relatively fixed, and the types of ornaments processed are relatively single, resulting in that each processing equipment can only process a single product; moreover, using the cylinder overturning fixture, due to the instability of the air source pressure, the cylinder stroke There will be a phenomenon that it is not in place, and it is difficult to...

Problems solved by technology

These two overturning forms make the angle of fixture overturning relatively fixed, and the types of ornaments processed are relatively single, resulting in that each processing equipment can only process a single product; moreover, using the cylinder overturning fixture, due to the instability of the air source pressure, the cylinder stroke There will be a phenomenon that it is not in place, and it is difficult to ensure the accuracy of repeated positioning after the fixture is turned over, and the noise of the cylinder is loud when it is working, polluting the environment; and the fixture that uses the eccentric gear to turn over, there is a large gap between the eccentric gear and the gear on the fixture, and the fixture Each flip will cause the gap value to accumulate, and it is easy to generate vibration during work, which will reduce the quality of the product
