[0002] Guide rail modules are primarily used in industrial automation to achieve linear or curvilinear motion of loads, making automated operations more flexible and precise. Through the combination of individual units, guide rail modules can accomplish linear and curvilinear motion of loads, making them particularly suitable for scenarios requiring high-precision operation. They are typically precision-designed, operate smoothly, and provide accurate positioning, effectively reducing errors and making them suitable for high-intensity working environments such as CNC machine tools and automated production lines.

[0003] Existing CNC machine tool guide rail modules cannot adjust the working height of the guide rail table during use, which makes it impossible to meet the needs of different usage heights. Secondly, the friction coefficient between the guide groove and the limit block is relatively large, which leads to greater mechanical wear between the guide groove and the limit block, resulting in a shortened service life. Therefore, there is an urgent need for a CNC machine tool guide rail module to solve the above technical problems. Utility Model Content

[0023] Please see Figure 1-5A guide rail module for CNC machine tools includes a guide rail table 1, a supporting base frame 2 at the bottom of the guide rail table 1, a left support seat 3 at the upper left end of the guide rail table 1, a right support seat 4 at the upper right end of the guide rail table 1, a screw 7 between the left support seat 3 and the right support seat 4, and a nut seat 9 installed on the screw 7 via a lead screw nut 8. Guide grooves 6 are provided on the front and rear sides of the upper end of the guide rail table 1. Scale lines 17 are provided on the front surface of the guide rail table 1. A power housing 5 is installed on the right side wall of the right support seat 4, and a motor mounting base 13 is installed at the bottom inside the power housing 5. A motor 10 is installed on the 13, and a coupling 11 is installed on the output shaft of the motor 10. The rightmost end of the screw 7 passes through the right support base 4 and the power box 5 and is connected to one end of the coupling 11. A heat dissipation vent 12 is opened on the right side wall of the power box 5. Two hydraulic cylinders 14 are installed on both sides of the bottom of the support base frame 2. Wear-resistant layers 16 are installed on the inner side walls of the two guide grooves 6 at the top of the guide rail table 1. Limit blocks 18 are connected to both ends of the bottom of the nut seat 9. The bottom of the two limit blocks 18 is inserted into the two guide grooves 6. The upper ends of the four hydraulic cylinders 14 are connected to the bottom of the guide rail table 1.

[0024] The four hydraulic cylinders 14 are arranged in pairs opposite each other about the support base frame 2. The four hydraulic cylinders 14 are connected in sequence by the support frame 15. The bottom of the support frame 15 is connected to the bottom of the inside of the support base frame 2.

[0025] The wear-resistant layer 16 is made of modified polytetrafluoroethylene.

[0026] The bottom of the guide rail platform 1 is in contact with the top of the support base frame 2, but the two are not connected.

[0027] The motor mounting base 13 has an L-shaped structure.

[0028] The bottom of the nut seat 9 is in contact with the upper surface of the guide rail 1, but they are not connected.

[0029] The working principle and usage process of this utility model are as follows: When working, the starting motor 10 drives the screw 7 on the coupling 11 to rotate. The rotating screw 7 drives the two limiting blocks 18 at the bottom of the nut seat 9 to move horizontally and linearly along the two guide grooves 6 through the lead screw nut 8.

[0030] When the operating height needs to be adjusted, the four hydraulic cylinders 14 inside the support base frame 2 are activated to move the guide rail 1 upward to the desired position, thereby meeting the needs of different operating heights. The inner sidewalls of the two guide grooves 6 at the upper end of the guide rail 1 are provided with wear-resistant layers 16. The wear-resistant layer 16 is made of modified polytetrafluoroethylene. By modifying polytetrafluoroethylene, the coefficient of friction between the guide grooves 6 and the limiting blocks 18 is reduced, thereby reducing the mechanical wear between the guide grooves 6 and the limiting blocks 18 and improving the service life.
