Title: COOLING CIRCULATION STRUCTURE FOR A NUMERICAL CONTROL MACHINE
TOOL AND NUMERICAL CONTROL MACHINE TOOL
The present invention relates to the field of numerical control machine tools, specifically to a cooling circulation structure of a numerical control machine tool and the numerical control machine tool.
The root cause of thermal deformation of machine tools is various heat sources. The spindle bearing is one of the largest heat sources, and the thermal deformation caused by this heat source directly affects the machining accuracy. If the temperature rise is not controlled in a timely manner, the spindle is easily damaged. Existing technologies generally add a cooling pump outside the machine tool, which pumps the cooled oil into the inner cavity of the spindle and then flows back to the cooling pump, taking away the heat generated by the spindle and limiting the temperature rise of the spindle. However, since the temperature sensor in the cooling pump is mainly used to detect the temperature of the return oil, and the temperature of the bearing is not consistent with the temperature of the return oil, this causes temperature errors and results in poor temperature control effect of the device, which cannot protect the spindle. Moreover, using only a cooling pump for oil circulation can no longer meet the heat dissipation requirements. In order to reduce the oil temperature, a more effective refrigeration equipment is needed.
In view of the shortcomings of the existing technology, the present invention discloses a cooling circulation structure of numerical control machine tool and numerical control machine tool, which can solve the problem that using only a cooling pump to achieve oil circulation cannot meet the heat dissipation requirements.
The cooling circulation structure of the numerical control machine tool includes a cooling circulation mounting base, a cooling circulation inlet channel, a cooling circulation outlet channel, and a cooling circulation heat exchanger. A cooling circulation cavity is formed inside the cooling circulation mounting base. The cooling circulation inlet channel is connected to one side of the cooling circulation cavity, and the cooling circulation outlet channel is connected to the other side of the cooling circulation cavity. Part of the cooling circulation heat exchanger is installed in the cooling circulation cavity, and the circulating oil liquid surrounds the cooling circulation heat exchanger. LU504478
The cooling circulation mounting base can help form a space for containing circulating oil liquid and can be moved as needed to adjust the relative position between the base and the numerical control machine tool. By using the cooling circulation inlet channel and the cooling circulation outlet channel together, the continuous flow of circulating oil liquid inside the cooling circulation mounting base can be achieved, which is beneficial for maintaining the continuous flow of circulating oil liquid. The cooling circulation heat exchanger can perform heat exchange in two ways: one is to replace the cooling circulation heat exchanger with a new one to maintain its temperature, and the other is to replace the temperature of the circulating liquid inside the cooling circulation heat exchanger to maintain its temperature.
Figure 1 is a schematic diagram of the structure of an embodiment of the present invention.
Figure 2 is a schematic diagram of the structure of an embodiment of the present invention in a top view direction (with one of the cooling circulation heat exchangers non represented).
In order to make the purpose, technical solution, and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them.
As shown in Figures 1 and 2, the cooling circulation mounting base 1 of the embodiment of the present invention includes a mounting base body 11 and a mobile universal wheel 12. The mobile universal wheel 12 can be installed at the bottom of the mounting base body 11 through bolt connection, and can be guided by the mobile universal wheel 12 when the cooling circulation mounting base 1 needs to be moved to different CNC machine tools for operation. Multiple inspection and sealing door bodies 13 can also be installed on the outer peripheral side of the mounting base body 11 through hinges, and can be opened when it is necessary to inspect the inside of the cooling circulation mounting base 1.
To solve the problem of improving the cooling effect and speed of the cooling circulation structure of the CNC machine tool, the cooling circulation cavity 14 can be formed with cavity openings by turning, and two cavity openings are formed on the upper surface of the cooling circulation mounting base 1. The upper surface of the cooling circulation mounting base 1 is reserved between the adjacent sides of the two cavity openings, so as to form the coolingU504478 circulation inlet channel 15 and the cooling circulation outlet channel 16 through subsequent machining processes.
To solve the problem of improving the convenience of connecting to the CNC machine tool, the three cooling circulation inlet channels 15 can be formed on the upper surface of the cooling circulation mounting base 1 by turning, and they are installed at intervals on the side of the two cooling circulation cavities 14. The three cooling circulation inlet channels 15 are installed on the same side of the cooling circulation mounting base 1.
To further solve the problem of improving the convenience of connecting to the CNC machine tool, the three cooling circulation outlet channels 16 are installed on the upper surface of the cooling circulation mounting base 1, and they are installed at intervals on the side of the two cooling circulation cavities 14. The three cooling circulation outlet channels 16 are installed on the same side of the cooling circulation mounting base 1.
In order to solve the problem of how to improve the heat exchange rate of circulating oil and reduce the energy consumption of circulating oil, two cooling circulation heat exchangers 2 are installed respectively in two cooling circulation cavities 14. The lower part of the cooling circulation heat exchanger 2 is installed in the cooling circulation cavity 14, and the upper part of the cooling circulation heat exchanger 2 extends out of the installation of the cooling circulation cavity 14.
It is easy to understand, after the cooling circulation heat exchanger 2 is placed in the cooling circulation cavity 14, the lower part of the cooling circulation heat exchanger 2 comes into contact with the circulating oil, while the upper part of the cooling circulation heat exchanger 2 comes into contact with air. The circulating oil relies on the heat conduction effect of the cooling circulation heat exchanger 2 to exchange heat with the circulating liquid inside the cooling circulation heat exchanger 2, and also exchanges heat with the air at the same time.
The cooling circulation heat exchanger 2 is equipped with an inlet opening 21 and an outlet opening 22, which are installed on opposite sides of the cooling circulation heat exchanger 2.
The numerical control machine tool described in the embodiment of the present invention includes a cooling circulation structure of the numerical control machine tool, and the cooling circulation structure of the numerical control machine tool is the same as any of the cooling circulation structures of the numerical control machine tool described in the above embodiments.
The above embodiments are only used to illustrate the technical solution of the present invention, rather than limiting it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the above embodiments, or equivalent replacements can be made to some technical features.
These modifications or replacements deU504478 not depart from the spirit and scope of the technical solutions of the various embodiments of the present invention.
