Description

Technical Field

[0001] This utility model relates to the field of machine tools, and in particular to a slide rail cooling structure and a machine tool including the slide rail cooling structure. Background Technology

[0002] When a slider moves along a guide rail, especially at high speeds, heat is inevitably generated due to rolling or sliding friction. In precision equipment, the heat generated by the slider movement of a linear guide rail can cause a series of negative effects, especially in scenarios requiring high precision and high stability. The main negative effects are as follows:

[0003] 1. Thermal deformation leads to a decrease in precision.

[0004] Heat generated by friction and mechanical motion is transferred to the guide rail, slider, and surrounding structure. Differences in the thermal expansion coefficients of different materials can lead to localized deformation. After thermal expansion of the guide rail or substrate, the actual position of the slider deviates more from its theoretical position (micrometer-level errors can affect machining accuracy). Localized deformation of the guide rail may alter the fit clearance between the slider and the guide rail, resulting in uneven motion resistance or jamming.

[0005] 2. Interference with surrounding systems

[0006] Heat can affect adjacent components through conduction or radiation, potentially causing signal distortion in temperature-sensitive elements (such as grating rulers and encoders) due to heat.

[0007] 3. Lubrication failure and increased friction

[0008] High temperatures accelerate the oxidation, volatilization, or viscosity reduction of lubricants (greases or lubricating oils). Insufficient lubrication leads to direct contact between the slider and guide rail, increasing the coefficient of friction and further raising the temperature (a vicious cycle). This dissolves the metal surface, accelerating wear due to lubrication failure and shortening the lifespan of both the guide rail and slider. Utility Model Content

[0009] In order to overcome the shortcomings of the existing technology, one of the objectives of this utility model is to provide a slide rail cooling structure that can rapidly cool down the slide rail.

[0010] In order to overcome the shortcomings of the existing technology, the second objective of this utility model is to provide a machine tool that can rapidly cool down the slide rail.

[0011] One of the objectives of this utility model is achieved through the following technical solution:

[0012] A slide rail cooling structure includes a base, a guide rail, and a slider. The guide rail is fixed to the base and extends in a straight line. The slider is slidably mounted on the guide rail. The base has cooling channels that are straight and parallel to the guide rail. The cooling channels are located at the bottom or side of the guide rail. The slide rail cooling structure also includes a cooling plate that is mounted on the top of the slider and has cooling channels inside.

[0013] Furthermore, the base is provided with a cooling groove, which is straight and parallel to the guide rail. The cooling groove is located at the bottom or side of the guide rail. The slide rail cooling structure also includes a first cooling pipe, which is installed in the cooling groove. The first cooling pipe has a hollow structure to form the cooling channel.

[0014] Furthermore, when the cooling channel is located on the side of the guide rail, the slide rail cooling structure also includes a side pressure block, which is located on the side of the guide rail and fixed to the base, and the cooling groove is located at the bottom of the side pressure block.

[0015] Furthermore, there are two guide rails, which are arranged parallel to each other with a gap between them, and the cooling groove is located between the two guide rails.

[0016] Furthermore, each guide rail has multiple sliders, and the cooling channels on the cooling plates of the multiple sliders are interconnected.

[0017] Furthermore, the cooling channels on the cooling plate are M-shaped.

[0018] Furthermore, the cooling plate includes a plate body and a second cooling pipe installed on the plate body. The plate body is provided with a mounting groove, and the second cooling pipe is installed in the mounting groove. The second cooling pipe has a hollow structure to form the cooling channel.

[0019] Furthermore, the slide rail cooling structure also includes a slide block, which is fixed to the slider and is in contact with the second cooling pipe.

[0020] The second objective of this utility model is achieved by the following technical solution:

[0021] Machine tools, including any of the above-mentioned slide rail cooling structures.

[0022] Compared to existing technologies, the base of the slide rail cooling structure of this utility model is provided with cooling channels. The cooling channels are straight and parallel to the guide rail, and are located at the bottom or side of the guide rail. The slide rail cooling structure also includes a cooling plate, which is installed on the top of the slider. The cooling plate has cooling channels inside. Through the above design, when the slide rail is in use, the heat generated by rolling friction or sliding friction is carried away by the cooling channels on the base, thus cooling the guide rail. The cooling channels on the cooling plate cool the slider, so that the slide rail cools down quickly, avoiding thermal deformation that leads to decreased precision, lubrication failure and increased friction, as well as interference with surrounding parts.

[0032] Please see Figures 1 to 5 The slide rail cooling structure of this utility model includes a base 10, a guide rail 20, a side pressure block 30, a first cooling pipe 40, a slider 50, a slide block 60, and a cooling plate 70.

[0033] The base 10 is linear and is used to fix the guide rails 20. The cross-section of the base 10 has a double-protruding structure, with the two top protrusions fixing the two guide rails 20. The two guide rails 20 are spaced apart and parallel to each other. The heat generated by the guide rails 20 during operation is conducted to the base 10. The base 10 is provided with cooling channels located at the bottom or side of the guide rails 20. Coolant flows through the cooling channels, and the flow of coolant carries away the heat from the top of the base 10, thus cooling the guide rails 20.

[0034] To prevent coolant leakage, a first cooling pipe 40 is provided. Therefore, a cooling groove 11 is provided on the base 10, located at the bottom or side of the guide rail 20. The cooling groove 11 is linear and used to install the first cooling pipe 40. The first cooling pipe 40 has a hollow structure to form a cooling channel. The first cooling pipe 40 is made of a thermally conductive material; in this embodiment, the first cooling pipe 40 is a copper pipe.

[0035] The side pressure block 30 is fixed to the base 10 and located on the side of the guide rail 20. The side pressure block 30 is located above the first cooling pipe 40 to prevent the first cooling pipe 40 from falling out of the cooling tank 11.

[0036] The slider 50 is slidably mounted on the guide rail 20. In this embodiment, two sliders 50 are mounted on the same guide rail 20.

[0037] A cooling plate 70 is fixed to the top of the slider 50. The cooling plate 70 has cooling channels inside to cool the slider 50. Specifically, the cooling plate 70 includes a plate body 71 and a second cooling pipe 72. The plate body 71 has a mounting groove 710 for mounting the second cooling pipe 72. The second cooling pipe 72 has a hollow structure, forming cooling channels. The second cooling pipe 72 is made of a thermally conductive material and is a copper pipe. In this embodiment, the second cooling pipe 72 is M-shaped, and the second cooling pipes 72 of adjacent cooling plates 70 on the same guide rail 20 are connected by pipes.

[0038] The slide block 60 is fixed to the top of the slider 50, and the slide block 60 is in contact with the upper surface of the cooling plate 70.

[0039] When the slide rail cooling structure of this application is in use, the slider 50 drives the slide block 60 to slide relative to the base 10 and the guide rail 20. Due to the heat generated by the rolling friction or sliding friction between the slider 50 and the guide rail 20, the cooling channels on the base 10 carry away the heat of the guide rail 20, thus cooling the guide rail 20; the cooling channels on the cooling plate 70 cool the slider 50, so that the slide rail cools down quickly, avoiding thermal deformation that leads to decreased precision, lubrication failure and increased friction, as well as interference with surrounding parts.

[0040] This utility model also discloses a machine tool including the above-mentioned slide rail cooling structure.

[0041] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of this utility model, and all of these fall within the protection scope of this utility model.
