[0012] In order to enable those skilled in the art to better understand the technical solution of the new experimental model, the preferred embodiments of the present invention are described below in conjunction with specific examples, but it should be understood that these descriptions are only for further illustrating the features and advantages of the present invention, rather than limiting the patent requirements of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0013] The present invention is further described below in conjunction with the accompanying drawings and preferred embodiments.

[0014] Example 1

[0015] See also Figure 1 and Figure 2 As shown, the present embodiment involves a support slide structure for a precision machine tool, comprising a slide rail body 1, the slide rail body 1 is composed of a bottom plate 2 extending horizontally to the left and right, and side plates 3 respectively arranged on the front and rear edges of the bottom plate 2, a slide groove 4 extending horizontally to the left and right is formed between the bottom plate 2 and the side plates 3, and cover plates 5 for closing the ends of the slide groove 4 are respectively provided at both ends, a moving block 6 is provided in the slide groove 4, and pulleys 7 rollingly connected to the bottom plate 2 are rotatably connected to the front and rear sides of the moving block 6, and a sliding hole 8 extending horizontally to the left and right is opened on the bottom plate 2, a screw rod 9 is rotatably connected between the cover plates 5, a screw rod nut 10 is threadedly connected to the screw rod 9, and a transmission block 11 passing through the sliding hole 8 and connected to the moving block 6 is provided on the screw rod nut 10, and one of the cover plates 5 is provided with a power source 12 for controlling the rotation of the screw rod 9.

[0016] Furthermore, the left and right sides of the moving block 6 are respectively provided with tension springs 13 located in the slide slot 4, one end of the tension spring 13 is connected to the cover plate 5, and the other end is connected to the moving block 6. By setting the tension springs 13 on the left and right sides of the moving block 6, the moving block 6 is tensioned on both sides during the movement of the screw nut 10, without offset, and the displacement is more accurate.

[0017] Further, the end plate of the side plate 3 is extended with a guide plate 14 that fits the wheel surface of the pulley 7. Through the setting of the guide plate 14, the upper and lower limit functions of the pulley 7 are played, so that the moving block 6 can move smoothly along the horizontal plane.

[0018] Furthermore, a threaded mounting hole 15 is provided on the upper end surface of the moving block 6 for connecting with external objects to achieve linkage.

[0019] Furthermore, the power source 12 is a motor whose output shaft is connected to the screw rod 9 .

[0020] Furthermore, a lubrication groove 16 is provided on the bottom plate 2 and is located below the pulley 7 .

[0021] In this embodiment, by operating the power source 12 (i.e., the motor), the screw 9 is rotated relative to the cover plate 5, so that the screw nut 10 moves left and right on the screw 9. After being transmitted by the transmission block 11, the moving block 6 connected thereto is driven to move left and right in the slide groove 4. Through the setting of the pulley 7, sliding is converted into rolling, and the pulley 7 is restricted between the base plate 2 and the guide plate 14, forming a good positioning, with little wear during the rolling process, resulting in smooth movement and high accuracy during long-term use.

[0022] By adding a proper amount of lubricant into the lubrication groove 16, the pulley 7 can be lubricated during the walking process to reduce wear.

[0023] The supporting slide groove structure for precision machine tools involved in the present invention drives the lead screw to rotate through a motor, and drives the lead screw nut and the connected moving block to move within a preset track. The movement is smooth, the lubricant consumption is small, the use is safe and reliable, the overall function is complete, and the practicality is strong.
