[0002] With the development of the times, the industrial level is constantly improving, and machine tools have become indispensable equipment for most precision parts processing. As an important part of machine tools, linear guides are used to ensure the stability and accuracy of high-precision parts processing. This technology includes highly accurate linear motion systems. When the linear guide is in working condition, the friction between the slide rail and the slider will generate high temperature. Usually, cooling pipes are set inside the slide rail to cool it down to avoid thermal deformation of the linear guide due to high temperature.

[0003] However, there is at least one of the following problems in the related technology: the heat generated by the linear guide pair in the working state is unevenly distributed. The cooling tube in the prior art can only perform a single cooling action due to its simple composition structure, and it is difficult to accurately control the temperature of the linear guide pair, resulting in the temperature of the linear guide pair cannot be effectively controlled, thereby causing the accuracy of the linear guide pair to decrease. Summary of the invention

[0004] The technical problem solved by the present invention is that the heat generated by the linear guide pair in the working state is unevenly distributed. The cooling pipe in the prior art can only perform a single cooling action due to its simple composition structure, and it is difficult to accurately control the temperature of the linear guide pair, resulting in the temperature of the linear guide pair cannot be effectively controlled, thereby causing the accuracy of the linear guide pair to decrease.

[0005] To solve the above problems, the present invention provides an intelligent cooling guide rail pair, which is controlled by an intelligent control system.

[0008] Compared with the prior art, the technical effect achieved by adopting this technical scheme is as follows: by dividing the slider into a detachable upper component and a lower component, a space for accommodating the first cooling component can be opened in the slider.

[0053] See also Figure 4 In one embodiment of the present invention, the single-chip microcomputer end 400 is controlled to control the refrigeration component to perform temperature control on the slider 100 and / or the slide rail 200 according to the temperature control guidance table, including: if the judgment is yes, the single-chip microcomputer end 400 is controlled to accept the parameters of the temperature control guidance table, and the refrigeration component is controlled to adjust the flow rate and pressure of the coolant; if the judgment is no, the refrigeration component is controlled to output full power to cool the slider 100 and / or the slide rail 200, and the judgment result is fed back to the artificial intelligence end 300 to regenerate the temperature control guidance table, and control the single-chip microcomputer end 400 to make a judgment again; wherein, the preset temperature range is 0-3 degrees Celsius.

[0054] The specific control methods are as follows: s1: The intelligent cooling guide rail pair starts working, the intelligent control system starts, and the current working condition data is collected through the temperature sensor and the external IoT terminal and transmitted to the artificial intelligence terminal; s2: The AI ​​end integrates and analyzes the data through an adaptive temperature control strategy model to form a temperature control guidance table; s3: The MCU receives the temperature control guidance table provided by the AI ​​end and determines whether the temperature difference is within 3 degrees Celsius; If the judgment is yes, go to s4, if the judgment is no, go to s5; s4: The MCU receives the parameters of the temperature control guide table, controls the water pump to adjust the flow rate and pressure of the coolant, cools down the slider and / or the slide rail, and enters s6; s5: Control the water pump to output full power, cool down the slider and / or the slide rail, and enter s6; s6: Determine whether the slider and / or the slide rail reaches the preset target temperature after being cooled by the coolant. If so, save the temperature control guidance table and the corresponding working conditions to the artificial intelligence end and end the temperature control; If the judgment is no, enter s3 and enter s1 at the same time.

[0055] It should be noted that in this embodiment, the friction between the slide rail 200 and the slider 100 generates heat, and the intelligent cooling guide rail pair provided in this embodiment is used to cool down. Under normal circumstances, the temperature detected by the temperature sensor 103 is greater than or equal to the preset target temperature, and the temperature difference is the temperature detected by the temperature sensor 103 minus the preset target temperature. In addition, this embodiment is only applicable when the temperature detected by the temperature sensor 103 is greater than or equal to the preset target temperature, and the preset temperature range is 0-3 degrees Celsius in absolute value. If the temperature detected by the temperature sensor 103 is less than the preset target temperature, the intelligent cooling guide rail pair provided in this embodiment does not perform the cooling action.

Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
