Problems solved by technology

[0003] The cooling system used by high-precision CNC machine tools today usually collects the sprayed and cooled coolant and then recycles it. However, in the prior art, the coolant is often filtered out of solid impurities and then returned to the tank where the coolant is stored. However, the low temperature of the coolant is maintained by continuously cooling the coolant in the storage box, but when the actual cooling is performed continuously for a long time, the effect of circulating cooling will rapidly deteriorate and affect the actual processing effect

Embodiment 1

[0033] refer to Figure 1-Figure 3 , a high-precision CNC machine tool cooling system, including a storage box 1, the top of the storage box 1 is connected to a liquid return pipe 2, the bottom of the storage box 1 is connected to a suction pipe 3, and the bottom of the storage box 1 is connected to a The air blowing pipe 4, the storage box 1 is provided with a filter mechanism 5, the top of the liquid suction pipe 3 and the air blowing pipe 4 is connected with a gas-liquid splitting mechanism 6, and the liquid pumping pipe 3 and the blowing pipe 4 pass through the gas-liquid splitting mechanism 6 Alternate connection, in actual use, the sprayed coolant is pre-filtered and then returned to the storage box 1 from the return pipe 2, and the coolant is drawn from the suction pipe 3 at the bottom through the separation of the filter mechanism 5 Perform spray cooling, inject cold air from the air blowing pipe 4 to the bottom of the cooling liquid during the process of extracting th...

Embodiment 2

[0039] Embodiment 2 includes all structures and methods of Embodiment 1, with reference to image 3 and Figure 8 , a high-precision CNC machine tool cooling system, also includes that the filter mechanism 5 is provided with a rotatable partition 17 in a conical structure, the bottom of the partition 17 is hollow, and the outer wall of the partition 17 is provided with multiple penetrations. The inner wall of the fixed groove is rotatably connected with a filter element 18 with a spherical structure. The filter element 18 is formed by splicing two arc-shaped filter plates 19. Between the two filter plates 19, a ring-shaped array of baffles is embedded and fixed. Plate 20, in actual use, uses the spherical filter 18 on the partition 17 to connect the inside and outside, so that the returning cooling liquid can be extracted again, and through the setting of the large-area solid partition 17, the gas-liquid splitting mechanism 6 is set In the interior, when circulating cooling, ...

Embodiment 3

[0044] Embodiment 3 includes all structures and methods of embodiment 1 and embodiment 2, with reference to figure 2 , a cooling system for a high-precision numerically controlled machine tool, further comprising: the cross-section of the storage box 1 is set to a square structure, the four corners of the inner wall of the storage box 1 are fixed with auxiliary miscellaneous removal mechanisms 28 extending vertically, and the storage box 1 The bottom ends of the four corners are connected with slag discharge pipes 101. In actual use, through the conical structure partition 17 and the storage box 1 with a square cross-section, the liquid flow and solid impurities that rotate with the partition 17 are stored. The difference in the four corners of the box 1 produces a change in the speed difference, so that the solid impurities collide with the inner wall of the four corners of the storage box 1 and the auxiliary miscellaneous discharge mechanism 28, thereby effectively concentra...

Abstract

The invention belongs to the technical field of numerical control machine tools, and particularly relates to a high-precision numerical control machine tool cooling system which comprises a storage box body, the top of the storage box body is connected with a liquid return pipe, the bottom of the storage box body is connected with a liquid pumping pipe, and the bottom of the storage box body is connected with an air blowing pipe. A filter screen mechanism is arranged in the storage box body, a gas-liquid distribution mechanism is connected between the top ends of the liquid extraction pipe and the air blowing pipe, and the liquid extraction pipe and the air blowing pipe are alternately communicated through the gas-liquid distribution mechanism. The liquid suction pipe sucks liquid from the storage box body and sucks air from the air blowing pipe at intervals, so that sprayed cooling liquid is rapidly and effectively cooled, reasonable utilization of energy is improved, a tool bit and a workpiece are cooled at intervals through liquid and air, and the cooling effect of an actual numerical control machine tool cooling system is improved.

Description

technical field [0001] The invention relates to the technical field of numerical control machine tools, in particular to a cooling system for high-precision numerical control machine tools. Background technique [0002] Numerical control machine tool is the abbreviation of digital control machine tool. It is an automatic machine tool equipped with a program control system. After calculation and processing, various control signals are sent by the numerical control device to control the movement of the machine tool. After processing, high-precision CNC machine tools are often equipped with a cooling system, which extracts coolant and sprays it on the cutter head and workpiece to cool down and cool down, so as to ensure the high-precision machining operations of the CNC machine tool. [0003] The cooling system used by high-precision CNC machine tools today usually collects the sprayed and cooled coolant and then recycles it. However, in the prior art, the coolant is often filt...
