A heat dissipation method, device, and ball screw feed system provided with the device

Abstract

The invention discloses a dual-drive ball screw feed system with heat dissipation function and a heat dissipation method. The heat dissipation method is specifically divided into the following steps: Step 1: Design a reasonable oscillating heat pipe, and add a The cooling medium with high capacity is sealed; step 2: set the oscillating heat pipe as described in step 1 inside the device that needs to dissipate heat; step 3: install a cooling device at one end of the oscillating heat pipe as described in step 2. The present invention improves the cooling efficiency of the heat dissipation device by designing a high-efficiency heat dissipation method and the heat dissipation device based on the heat dissipation method, and makes the cooling system more friendly to the environment. The system controls the temperature difference in the low-temperature section of the oscillating heat pipe by adjusting the flow and temperature of the low-temperature cooling gas, and realizes real-time regulation of the temperature field and thermal deformation of the ball screw feeding system.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a heat dissipation method, a device and a ball screw feed system provided with the device. Background technique [0002] Modern CNC machine tools have increasingly high requirements for machining efficiency and precision. As a key component of machine tools, the feed system directly affects the machining accuracy of machine tools. It is a necessary key functional component to achieve high-speed and high-precision machining. During the machining process of machine tools, such as frictional heat generation of ball screw pairs, frictional heat generation of rolling bearings, etc., many factors will cause uneven distribution of temperature field in the feed system and cause thermal deformation, which will affect the machining accuracy of CNC machine tools. Therefore, certain measures must be taken to control the temperature rise and thermal deformation of the feed system of the machine tool ...
