The invention discloses a clamping and feeding mechanism for adjusting the cylindricity of a semiconductor silicon rod. The clamping and feeding mechanism comprises a feeding sliding table, an adjusting assembly, a rotary connecting table and a clamping mechanism arranged on the rotary connecting table. The rotary connecting table is arranged on the feeding sliding table and driven by the adjusting assembly to horizontally rotate, multiple pressing plates are arranged on the feeding sliding table, the pressing plates are arranged into L-shaped structures, one ends of the pressing plates are detachably mounted on the feeding sliding table, and the other ends of the pressing plates are arranged on the rotary connecting table. The clamping mechanism comprises a headstock assembly and a tailstock assembly opposite to the headstock assembly. A convex block is arranged at one end, in the feeding direction of the rod, of the rotary connecting table, the headstock assembly is fixedly mounted on the convex block, and the tailstock assembly can be slidingly mounted on the rotary connecting table in the feeding direction of the rod back and forth. The clamping and feeding mechanism can clampthe rod and drive the rod to rotate, the axis direction of the rod can also be adjusted, round rod grinding of the rod is achieved, and the cylindricity requirement is met.
Description
technical field [0001] The invention relates to the technical field of silicon rod processing equipment accessories, in particular to a clamping and feeding mechanism for adjusting the cylindricity of semiconductor silicon rods. Background technique [0002] When the semiconductor spheronizer grinds the bar, the clamping mechanism clamps the bar and rotates the silicon rod for spheroidal grinding. The angle of the bar axis relative to the grinding feed direction in the clamping mechanism of the existing semiconductor spheronizer is a fixed value and cannot be adjusted, and it completely depends on the state of the equipment when it is assembled. When the round bar needs to be ground, the working condition that the bar axis deviates from the grinding feed direction occurs, the angle adjustment of the bar axis cannot be realized, the requirement for the cylindricity of the silicon rod cannot be met, and the production demand cannot be met. In view of the above problems, the p...
