Description

Technical Field

[0002] When processing quartz round rods, since quartz round rods are brittle materials, when processing quartz round rods, graphite jigs and silicon carbide products are usually heated with a flame spray gun first, and then special wax is applied to the heated jig. After the quartz round rods to be processed are placed, they are processed after they are completely cooled. The special wax cools slowly, and the workpiece needs to be heated with a flame to remove it after processing, which can easily cause deformation of weak parts of the workpiece, or local heating to cause the workpiece to burst, and the processing efficiency of the above method is low.

[0003] The prior art (CN211842619U) discloses a clamp for drilling holes in quartz round rods. The quartz round rod is fixed by clamp one for drilling, thereby ensuring the parallelism and flatness of the multiple holes; the quartz round rod is fixed by clamp two for chamfering, thereby ensuring the parallelism and uniformity of multiple chamfers; in addition, the arc-shaped clamping ring is elastic, the auxiliary groove is opened, and the quartz round rod can be fixed by lifting the telescopic rod to a certain height with the help of a micro-cylinder. The quartz round rod can be punched or chamfered by clamp one or clamp two, thereby achieving the fixation of quartz round rods of different diameters.

[0004] In the prior art, when a pair of quartz round rods are fixed by a clamp, the clamp is in rigid contact with the quartz round rod. Since the quartz round rod is a brittle material, if the force exerted by the clamp on the quartz round rod is too large, the quartz round rod may be damaged, thereby reducing the quality of the product.
