Centralized temperature management system of metal cutting machine of numerical control machine tool

Abstract

The invention relates to a centralized temperature management system of a metal cutting machine of a numerical control machine tool. A system controller is respectively connected with an energy adjusting valve, a flow distributor and a return water controller; a refrigeration compressor is respectively connected with a condenser, the energy adjusting valve and an evaporator; the evaporator is respectively connected with the energy adjusting valve, a throttle valve, a return water controller and a refrigerating medium box; the refrigerating medium box is connected with a refrigerating medium pump; the refrigerating medium pump is connected with the flow distributor; the flow distributor is respectively connected with a cooling subassembly; and the return water controller is respectively connected with an electrical cabinet cooling subassembly, a spindle cooling subassembly, a rotary table cooling subassembly, a linear motor cooling subassembly, a hydraulic station cooling subassembly and a cutting liquid cooling subassembly. Refrigerating media can be cooled down by refrigerating equipment, the design of the machine tool is simplified, energy consumption is reduced, occupied area is reduced, the failure rate is reduced, the cost is also reduced, the reliability is improved, and the temperature control precision of the machine tool is improved.

Description

technical field [0001] The invention relates to a cooling device, in particular to a centralized temperature management system for a CNC machine tool metal cutting machine tool. Background technique [0002] With the development of the CNC machine tool industry, the machining accuracy of the machine tool is becoming more and more refined, the stability of the machine tool is getting stricter, and the use efficiency of the machine tool is getting higher and higher. Therefore, the requirements for the overall stability and reliability of the CNC machine tool are getting higher and higher. more harsh. In order to adapt to such high-strength, high-efficiency, and high-precision work requirements, modern CNC machine tools have put forward clear requirements for the cooling of each component. The main shaft of the machine tool, linear motor, hollow screw, turntable, hydraulic station, cutting fluid , Electrical cabinets and other components need to be cooled. Therefore, it often...
