Inner cooling switching sleeve for hole making of wind-power bearing ring

Abstract

The invention relates to an inner cooling switching sleeve for hole making of a wind-power bearing ring. One end of a switching sleeve main body is inserted into a main shaft sleeve and is contacted with a main shaft in the main shaft sleeve, the main shaft sleeve is provided with an inner hexagonal jack screw to tighten the switching sleeve main body, a U drill is inserted from the other end of the switching sleeve main body, the switching sleeve main body is provided with two inner hexagonal jack screws to position and clamp the U drill, the switching sleeve main body is provided with a through hole as a cooling hole, and the cooling hole is formed between the U drill and the main shaft. By adopting the inner cooling switching sleeve for the hole making of the wind-power bearing ring, the problem that durability of a cutter and processing quality of a product are influenced as cooling liquid is difficult to enter a processing region, heat dissipation conditions are poor, heat in a hole making region is concentrated and temperature of the hole making region is high can be solved, and stability and safety in a processing process can be better guaranteed.

Description

technical field [0001] The invention relates to the field of wind power bearing ring hole processing, in particular to an internal cooling conversion sleeve used for wind power bearing ring hole processing. Background technique [0002] With the depletion of traditional energy and the increasing environmental pollution, wind energy, as a green energy, has been paid more and more attention by people. In order to better develop and develop wind power products, the state has given many favorable policies to encourage enterprises to move closer to wind power products, produce energy-saving and environment-friendly products, revitalize and develop national industries, and further develop new industries. The state's efforts to encourage the development of new energy sources have been continuously strengthened, prompting the emergence of various energy products. [0003] When processing wind power products, the processing of bearing ring holes will encounter various problems, such...

AI Technical Summary

Problems solved by technology

In the process of bearing ring hole processing adopted in the prior art, it is difficult for the coolant to enter the processing area, the heat dissipation conditions are not good, the heat concentration in the hole processing area is high, and the temperature is high, which affects the durability of the tool and the processing quality of the product. The hole is easy to be blocked, resulting in chips that cannot be discharged normally, so that there will be roughening of the processed hole wall, and the workpiece will be scrapped

Over time, because the chips are difficult to remove, it will also cause the coolant to become dirty, which will affect the tool and the tool holder. Because the coolant is too dirty, the chips will stick to the tool holder, causing the torque of the cutter holder to increase and cause twisting, which will eventually cause the tool holder to be damaged. The failure consequence of being scrapped due to failure of normal use, and the workpiece has to be scrapped
