Support for disposable cutting wire wheel for shaft

Abstract

The invention discloses a support for a disposable cutting wire wheel for a shaft, which is characterized by comprising a positioning base (1), a core shaft (8), a positioning sleeve (2), a compression sleeve (4) and a compression nut (7), wherein a positioning base round platform is arranged on the positioning base (1), the compression sleeve (4) is sheathed on the core shaft (8), a compression sleeve round platform is also arranged on the inner side, the positioning sleeve (2) is sheathed on the core shaft (8), the diameter of the positioning sleeve (2) is the same with that of the compression sleeve round platform and that of the positioning base round platform, a disposable cutting wire wheel (3) is sheathed on the outer circular surface of the positioning base round platform, the compression sleeve round platform and the positioning sleeve, and the disposable cutting wire wheel (3) is fixedly connected with the positioning base (1); and a thread is arranged at the other end of the core shaft (8), and the compression nut (7) is matched with the thread and further extrudes the end surface of the compression sleeve (4) together with a spring pad (5) through a flat pad (6) sheathed on the core shaft (8). The support has simple structure and low using cost, and can greatly reduce the production cost.

Description

technical field [0001] The invention relates to a wafer disposable cutting support. Background technique [0002] At present, the metal wires used in the multi-wire cutting machine for cutting wafers are all wound on the wire wheel of the machine. The wire pay-off wheel bears a large tension, so the requirements for the material are very high. The self-weight is 21 kg. The weight of each reel on the reel is 20 kg. It is very laborious for workers to get on and off the line, and a little carelessness may cause equipment or personal accidents. The pay-off wheel is reused, and the wheel must be transported to the metal wire production plant for winding every time. The round-trip transportation is not only expensive, but also has a long cycle. For the convenience of users, some metal wire manufacturers in China have invented the shaft one-time cutting wire wheel. If the shaft one-time cutting wire wheel is used, the weight of a coil of wire can be reduced to 20 kg, and it can b...
