An active top tooling

Abstract

The invention relates to a novel movable centring tool for guide wheel slotting. The movable centring tool is specially designed for the guide wheel slotting in the photovoltaic industry and can bear guide wheels with the length larger than 1000mm and smaller than 1500mm and the weight smaller than or equal to 500kg, the axial centring force can reach 900 Kgf (kilogram-force), and the spherical jitter value, measured through a micrometer gauge after assembling, is smaller than 0.007mm. The movable centring tool is accurate in centralized positioning, convenient to operate, low in labor intensity and capable of completing clamping of a workpiece at one step; a framework oil seal arranged inside the movable centring tool can prevent water and dust; a water shield integrated with the outer circle of a tailstock taper hole is designed externally, so that water and garbage can be more effectively prevented from entering transmission parts.

Description

technical field [0001] The invention relates to a movable top tool for slotting a guide wheel. Background technique [0002] With the increase of human demand for energy, solar energy has become a new energy source in front of people, and the silicon wafer cutting technology of solar cells mostly adopts the more advanced multi-wire cutting technology in the world at present. The high-speed reciprocating motion brings the abrasive into the processing area to grind the workpiece. During the cutting process, the steel wire is guided and reversed by the guide wheel to form a wire mesh on the wire roller, and the ingot passes through the wire mesh at a slow speed. , which can be cut into pieces. [0003] During the cutting process, the guide wheel can bury the steel wire part of the wire mesh and prevent it from slipping. The wire jumper plays a better role in stability and guidance. Therefore, in the slotting process of the guide wheel, the processing accuracy of the guide whee...

Problems solved by technology

[0003] During the cutting process, the guide wheel can bury the steel wire part of the wire mesh and prevent it from slipping. The wire jumper plays a better role in stability and guidance. Therefore, in the slotting process of the guide wheel, the processing accuracy of the guide wheel is higher. , and the length of a single piece of guide wheel exceeds 1000MM, the weight reaches 500KG, the bearing capacity is large, the bearing capacity of ordinary heavy-duty tops is poor, the service life is short, the accuracy is poor, the rework rate is high, the production cost is high, and secondary clamping is required, and the labor intensity is high. , is not conducive to the actual production operation
