Cooling system of pivoting equipment

Abstract

A cooling system of pivoting equipment is suitable for providing cooling fluid for cooling the pivoting equipment. The cooling system comprises a thermal elongation measuring device, a cooling machine and a control unit. The thermal elongation measuring device is combined on the pivoting equipment and is used for measuring the elongation generated after the the pivoting equipment is heated in the rotating process. The cooling machine is connected with the pivoting equipment and can be controlled to provide cooling fluid for the pivoting equipment. The control unit is in signal connection with the thermal elongation measuring device and the cooling machine, and the control unit controls the cooling machine to provide the cooling fluid for the pivoting equipment according to the elongation measured by the thermal elongation measuring device. The cooling system contributes to cooling the pivoting equipment, the service life of the pivoting equipment is prolonged, and the thermal elongation of the pivoting equipment can be restrained through cooling of the cooling machine so that the machining precision can be improved.

Description

technical field [0001] The invention relates to a cooling system, in particular to a cooling system of a shaft-rotating device comprising a rotatable rod body. Background technique [0002] In known machining techniques, to process a workpiece, the workpiece is mounted on a worktable, which is mounted on a screw of a machine tool, and the screw is mounted on a bearing and driven by a motor Drive the screw to rotate, and when the screw rotates, it can drive the workbench and the workpiece to move in a straight line, and at the same time process the workpiece through appropriate tools. However, due to the continuous rotation of the screw during processing, the joint between the screw and the bearing will be heated due to long-term rotational friction, which will increase the temperature of the screw, and the metal screw will undergo thermal expansion and thermal elongation after being heated, resulting in The positioning accuracy error will affect the processing precision, an...

AI Technical Summary

Problems solved by technology

Among them, because the screw continues to run, the first temperature sensor is not suitable for installation on the screw, so the first temperature sensor is installed on the base, but also because of this, the temperature of the base should be used to represent the temperature of the screw , which is not directly nor precisely

And because the base is bulky, it takes a long time until the base and the screw reach thermal equilibrium, and the temperature of the base is also easily affected by the ambient temperature, which makes the temperature measurement not direct, accurate or sensitive enough

Therefore, the cooling system uses the detected temperature to control the design of the cooling screw of the cooler, which is still not ideal.

[0005] In addition, it is not easy to install temperature sensing equipment during the rotation of the rotating rod, and friction cannot be avoided during the rotation process, so there is currently no abutment type thermal elongation measurement equipment on the market, which cannot effectively reduce the measurement cost
