The utility model relates to a rotor passes through axle lead structure belongs to motor technical field. The structure includes: rotor shaft, it has deep hole and with deep hole connection's inclined hole, passes through axle conducting row, penetrates deep hole and inclined hole, fills with potting glue between passing through axle conducting row and deep hole, is provided with insulating block between passing through axle conducting row and inclined hole, and pressing plate is connected with rotor shaft through fastener, and pressing plate at least partial contact with insulating block is used for pressing insulating block. Insulating block is half formula epoxy pad, and its inside side contacts with potting glue and is fixed by it. One insulating block is equipped with two pressing plates, and there is gap between two pressing plates for passing through axle conducting row. Passing through axle conducting row is multilayered flexible conducting sheet. The one end of rotor shaft away from inclined hole is provided with cover plate, and potting glue hole is set up on cover plate for potting glue injection. The utility model discloses simple structure, and easy installation can effectively prevent potting glue leakage, reduce the damage of insulating block to passing through axle conducting row under the action of centrifugal force, improve the reliability and service life of rotor passes through axle lead structure.

The invention relates to the technical field of diamond wire cutting, in particular to diamond wire cutting liquid as well as a preparation method and application thereof. The diamond wire cutting liquid provided by the invention comprises the following components in percentage by mass: 15-20% of a dispersing agent, 20-22% of a wetting agent and the balance of water, the dispersing agent comprises isooctyl phenol polyoxyethylene ether; the wetting agent comprises fatty alcohol polyether which is obtained by sequentially grafting polypropylene oxide, polyethylene oxide and polypropylene oxide by taking octanol as an initiator. The diamond wire cutting fluid has excellent dispersion, lubrication, wetting, liquid carrying and other properties, reduces cutting resistance in the cutting process and abrasion of a diamond wire, enhances cutting force, improves stability in the cutting process, and reduces the probability of generating wire marks.
