Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machining, and relates to a heat dissipation structure configured for a cooling pump station of a machine tool. Background Art

[0002] In the field of industrial automation, machine tools are the core equipment for processing and manufacturing, and their operating efficiency and stability are directly related to production benefits. During long-term, high-intensity working, machine tools will generate a lot of heat. If they are not cooled in time and effectively, it will not only affect the processing accuracy of the machine tools, but may also cause damage to the machine tools, thus affecting the normal operation of the entire production line.

[0003] The machine tool cooling pump station mainly transports coolant to the cutting area of ​​the machine tool through the cooling pump circulation system, and uses the specific heat capacity and fluidity of the coolant to quickly absorb and take away the heat generated in the cutting process. The design of the existing cooling pump station takes into account the requirements of machine installation specifications, and usually adopts an embedded installation structure for external arrangement with the machine tool. Its arrangement method causes the installed cooling pump host and the cooling pipeline connection end to often store relatively high local heat. Since the circulating cooling of the pump body is greatly limited by the cooling pipeline flow, the existing small machine tool cooling pump station is greatly affected by local heat, and the actual cooling effect is not ideal.

[0025] At the same time, the heat sink fins 8 and the fan group 9 structure arranged in the air bin 3 are combined to cooperate with the heat of the coolant outside the wall of the return tube 6, and the heat sink fins 8 structure is used to contact and absorb the heat of the air bin 3 and the return tube 6 surface, and the fan group 9 blows airflow to contact the heat sink fins 8, so as to conduct heat exchange between the airflow and the heat sink fins 8, and guide the heat to be discharged outside the air bin 3, so as to dissipate the heat locally on the structure of the base frame 1, and realize the local heat dissipation of the configuration of the cooling pump station;

[0026] Compared with the traditional cooling pump station configuration, this structure can effectively use the heat of the cooling pump station and the coolant pipeline of the return pipe 6 to cooperate with the heat dissipation structure to locally dissipate heat for the base structure, so as to avoid the influence of local heat on the cooling effect of the cooling pump station, thereby improving the practicality of the structure.

[0027] Preferably, the lathe cover plate 2 is an aluminum profile plate frame installed by upper interlocking. The lathe cover plate 2 adopts an upper interlocking installation structure, which can be conveniently overlapped and installed with the bottom structure of the machine tool, so as to ensure the heat dissipation effect of the slot plate 5 in combination with the setting position of the slot plate 5.
