A cooling device and method for large-scale spindle and bearing assembly process

Abstract

The invention discloses a cooling device and method used in the assembly process of a large main shaft and a bearing. The device includes an air cover connected to a fan coil through an air pipe. The windshield is composed of two detachable half-pipes. A number of spiral deflectors are uniformly arranged on the inner peripheral wall of the windshield. The axial profile formed by the combination of the spiral deflectors matches the shape of the workpiece to be cooled. A temperature sensor is installed at the center of the outlet of the wind hood, the temperature sensor is connected to the PLC, and the PLC is connected to the fan coil unit. The method steps are as follows: assemble the workpiece to be cooled and the air cover, connect the air cover with the air pipe; turn on the fan coil, the cold air will flow through the air pipe along the spiral deflector of the air cover, and be discharged after heat exchange; the temperature sensor measures the temperature at the outlet. The airflow temperature is fed back to the PLC, and the PLC automatically controls the fan coil to adjust the cooling capacity. The invention has the advantages of simple structure, reasonable design, low cost and remarkable effect, shortens the cooling time and improves the production efficiency of the enterprise.

Description

technical field [0001] The invention relates to the field of large-scale main shaft and bearing assembly process, in particular to a cooling device and method used in the large-scale main shaft and bearing assembly process. Background technique [0002] For a long time, in the assembly process of large spindles and bearings, natural cooling has been used for cooling. However, due to the large volume of the workpiece to be cooled, it takes a long time to perform natural cooling, and the waiting time for the workpiece to enter the next process is too long, resulting in low manufacturing efficiency in the factory. [0003] Chinese Patent No. [201910667211.3], publication (announcement) date 2019.09.20, a conveying cooling device for castings invented by Huaxinglong, which adopts the method of sprinkling water to cool down. This method is suitable for casting cooling, not suitable for shafts that have been surface-processed, it is easy to make the shaft brittle and damage the m...
