[0002] The gemstone carving robot is a device used for gemstone facet molding. Before the equipment is used, it needs to carry out the bonding operation of gemstones (here refers to cylindrical zircon), that is, the gemstones need to be bonded and then facetted. However, Bonding is one of the most critical steps in gem carving, which has a great impact on the quality of gem processing. This equipment has two main requirements for the bonding effect. One is that the bonding must be firm, and the other is that the bonding must be neutral. In order to achieve this Two requirements, the operator must have certain experience and the operation is more complicated, resulting in low efficiency and low accuracy of gemstone bonding

Embodiment Construction
[0019] The present invention will be further described below in conjunction with accompanying drawing.
[0020] Such as Figure 1-4 As shown, this embodiment provides an adjustable jig for gemstone positioning, which includes a jig body 3 and a jacket 5 with knurling on the outer periphery. A collet 7, a tapered expansion ring 8, a threaded section 9, and a fastener mounting hole 4 are provided in sequence.
[0021] The elastic collet among the present invention is used for adjusting and positioning when gemstones are clamped. The collet 7 is a cylindrical elastic collet made of 304 stainless steel. Four notches 10 are provided on the collet along its circumferential direction. , the notch extends from the end face of the collet to the taper sleeve or the screwed external thread section. On the one hand, it has a certain elasticity to adapt to the size of the gemstone for fine adjustment, so that the gemstone can be quickly clamped and positioned; On the one hand, by tighten...

The invention discloses a gem clamp with adjustable positioning. The gem clamp with adjustable positioning comprises a clamp main body and a jacket; the interior of the clamp main body is hollow; an elastic clamping head, a conical expanding ring, a screwing outside thread segment used for being connected with the jacket and a fastener mounting hole used for fastening the clamp main body and a drive piece output shaft, wherein the small end of the conical expanding ring is connected with the clamping head, and the large end of the conical expanding ring is connected with the screwing outside thread segment; a conical sleeve is arranged on the jacket, corresponding to the conical expanding ring; the conicity of the conical sleeve is smaller than that of the conical expanding ring; the jacket sleeves the clamp main body; and when a gem needs to be clamped, the jacket is screwed with the clamp main body through threads, and the conical sleeve tightens the conical expanding ring, thus the clamping head clamps the gem. According to the gem clamp with adjustable positioning, the gem does not need to be clamped by an adhesive adhesion rod, centering clamping and rapid and simple installation can be rapidly realized, and the efficiency and the reliability of gem clamping are improved.
