Description

Technical Field

[0001] The utility model relates to the field of electric spindle processing, in particular to a cooling device for electric spindle processing. Background Art

[0002] In the process of electric spindle processing, in order to better process products, it is necessary to rotate at a high speed continuously. Since a large amount of heat will be generated during the operation of the electric spindle, if these heats cannot be dissipated in time and effectively, the temperature of the electric spindle will rise. The increase in the temperature of the electric spindle will have a negative impact on its thermal characteristics and dynamic characteristics, thus affecting its normal operation, and may even lead to equipment damage or a decrease in processing accuracy. Therefore, during the operation of the electric spindle processing, it is necessary to continuously cool and lower the temperature of the electric spindle to extend its service life. The traditional cooling of the electric spindle mainly uses a fan to blow air continuously to cool down, but the cooling effect of the fan on the electric spindle is poor. Therefore, a cooling device for electric spindle processing is needed to solve the above problems.

[0003] Chinese Patent No. CN216989891U discloses a cooling structure for an electric spindle for mold processing, including an electric spindle main body and a cooling component. The cooling component is installed on the surface of the electric spindle main body; the cooling component includes a cooling shell. Both the top and bottom of the inner wall of the cooling shell are fixedly connected with two mounting bearings. A cooling shaft is connected between the corresponding two mounting bearings. Both the left and right sides of the cooling shaft are fixedly connected with connecting blocks, and the surface of the connecting block is fixedly connected with cooling fan blades. Through the mutual cooperation of the electric spindle main body and the cooling component, the utility model realizes a cooling structure for an electric spindle for mold processing, and synchronously uses the rotation force of the electric spindle itself to drive the cooling fan blades, so as to dissipate heat from the electric spindle main body, accelerate the air flow around the electric spindle main body, save energy while extending the service life of the electric spindle, and moreover, the cooling component is also easy to disassemble from the surface of the electric spindle main body, which is convenient for its maintenance and repair.

[0004] In the above patent, the rotation of the cooling fan blades is driven by the rotation of the electric spindle. However, during the operation of the electric spindle, the rotation speed is relatively high, and it is easy to occur that the cooling component falls off from the device, and improving the air flow rate has a poor cooling effect on the electric spindle.
