Silicon rod rotary floating cutting CNC machine tool

Abstract

The invention discloses a rotary floating cutting numerical control machine tool for a silicon rod, and relates to a numerical control machine tool, in particular to a numerical control cutting machine for cutting the silicon rod. The rotary floating cutting numerical control machine tool comprises a numerical control box, a machine tool body, a transmission mechanism, and a cutting mechanism and a silicon rod clamping mechanism which are arranged on the machine tool body, and is characterized in that the silicon rod clamping mechanism comprises a driving rotation support wheel which clamps the silicon rod in a matching manner in the vertical direction, and a floating rotary pressing wheel; the floating rotary pressing wheel is connected with an elastic pressing device which drives the floating rotary pressing wheel to tightly press the silicon rod; and the transmission mechanism is connected with a shaft of the driving rotation support wheel. The rotary floating cutting numerical control machine tool can realize the non-concentric axial rotation floating radius cutting of polycrystalline silicon rods which have the characteristics that the material texture density is sparse, workpieces are bent in the axial direction, ovality exists in the diameter direction, the diameters are different, the appearances are not irregular, the breaking phenomenon is easy to generate, and the like in the floating rotation state, and is novel and capable of realizing the automatic radius cutting.

Description

technical field [0001] The invention relates to a numerical control machine tool, in particular to a numerical control cutting machine for cutting silicon rods. Background technique [0002] At present, in the domestic polysilicon industry manufacturers, it is necessary to cut the restored silicon rods with a diameter of 2-8 inches radially to length for finished product inspection and to meet the production needs of different next processes. [0003] The patent number is 200920287130.2, and the Chinese patent "single / polycrystalline silicon rod cutting machine" with a publication date of 2010.12.22 discloses a silicon rod cutting machine, which includes a crystal rod fixing device, a cutting system and a cooling system. The crystal rod The fixing device includes a number of fixed clamping devices, which are arranged on the workbench, and the fixed clamping devices are respectively arranged on the left and right sides of the grinding wheel. In addition, the workbench is prov...

Problems solved by technology

For this kind of silicon rod to be cut, when the old-fashioned CNC cutting machine is used to position the silicon rod with single-point forced pressure, and the cutter head tool is used for radial full-diameter cutting, the silicon rod itself is subject to great vibration, and the cutting direction cannot be in line with the silicon rod. The axis of the rod bending remains vertical, the cut part is easily broken, and it is difficult to cut out the finished product

This traditional cutting process and equipment not only caused great economic losses, but also delayed the production of the next process, which greatly increased the production cost of the enterprise.
