[0004] In the prior art, the following deficiencies exist:

[0005] 1) Manual screw rod adjusting mainly depends on the experience and hand feeling of the operator to control the rotation amplitude, and it is difficult to realize high-precision height adjustment.

[0006] 2) After the work plane is raised or lowered, there is lack of effective locking and stabilizing mechanism. Under the action of external force such as vibration and cutting force generated by the machine tool during the machining process, the work plane is easy to displace or shake, which destroys the relative accurate position of the machining tool and the workpiece. Not only affects the machining precision, but also may cause damage to other parts of the machine tool in the long run, shortens the service life of the machine tool. INVENTION CONTENTS

[0025] Please refer to the attached Figure 1 - attached Figure 4 As shown, the bottom fixed connection of connecting plate 203 has two tooth columns 204, the outer wall of each tooth column 204 is all sleeved with sleeve 205 connecting plate 203 bottom fixed connection two tooth columns 204 and sleeve 205 mutually cooperate, further enhance the stability of lifting mechanism 2 operation, tooth column 204 is sleeved in sleeve 205, in the process of electric telescopic handle 202 driving connecting plate 203 ascending or descending, tooth column 204 along the inner wall of sleeve 205 slides, limit the displacement of connecting plate 203 in horizontal direction, make lifting process more stable, avoid the shaking or inclination of work plane 5, ensure the precision of workpiece in processing.

[0026] As Figure 1As shown, the outer wall of each sleeve 205 is provided with a contact groove 215, and the top of the bottom plate 1 is fixedly connected with two second supports 206. The contact groove 215 in the outer wall of each sleeve 205 interacts with the gear 208, adding auxiliary power and control mechanism for the operation of the lifting mechanism 2. When the gear 208 rotates, the teeth of the gear 208 and the contact groove 215 are engaged with each other. While the connecting plate 203 is pushed up or down by the electric telescopic rod 202, the rotation of the gear 208 can provide additional power for the movement of the tooth column 204, so that the lifting or lowering process is more smooth. By controlling the rotation speed and direction of the gear 208, the running speed and position of the lifting mechanism 2 can be adjusted to a certain extent, further improving the accuracy of the height adjustment of the work plane 5.

[0027] Please refer to the attached drawings Figure 1 -attached drawings Figure 4 As shown, the opposite sides of the two second supports 206 are movably inserted with a rotating column 207, and the two ends of the rotating column 207 are fixedly connected with a gear 208. The second support 206 is fixed on the top of the bottom plate 1, which provides stable support and installation position for the rotating column 207. The gear 208 fixedly connected at both ends of the rotating column 207 is engaged with the contact groove 215 in the outer wall of the sleeve 205 to participate in the operation control of the lifting mechanism 2. The rotation of the gear 208 not only assists the movement of the tooth column 204, but also realizes more accurate adjustment of the height of the work plane 5, improving the intelligence and refinement of the machine tool base structure in height adjustment.

[0028] Please refer to the attached drawings Figure 1 -attached drawings Figure 4 As shown, the top of the bottom plate 1 is fixedly connected with a group of third supports 3, and the third supports 3 are also fixed on the top of the bottom plate 1. The third supports 3 mainly bear the role of supporting the panel 4. The panel 4, as the lower supporting structure of the machine tool work plane 5, cooperates with the third supports 3 to provide stable horizontal support for the work plane 5. When the machine tool is working, the panel 4 can evenly disperse the pressure borne by the work plane 5, prevent the work plane 5 from deforming due to uneven stress, and ensure the flatness of the work plane 5, thereby ensuring the machining precision and quality of the workpiece in the machining process.

[0029] Please refer to the attached drawings Figure 1 -attached drawings Figure 4As shown, the top of the third support 3 is fixedly connected with a support panel 4, and the top of the connecting plate 203 and the bottom of the working plane 5 are fixedly connected. The working plane 5 directly contacts the workpiece and is the actual working area of the machine tool for various machining operations. It is fixedly connected with the top of the connecting plate 203 and can realize height adjustment under the action of the lifting mechanism 2, meet the needs of different machining tasks, and the flatness and stability of the working plane 5 itself play a decisive role in machining precision. Under the cooperative matching of the whole machine tool base structure, the working plane 5 can provide a stable and reliable working platform for the machining of the workpiece, ensuring the smooth progress of the numerical control machine tool machining process and the high standard requirement of the machining quality.

[0030] Working principle: when the height of the work plane 5 of the numerical control machine tool needs to be adjusted, the whole machine tool base structure works cooperatively. First, the electric telescopic rod 202, as the core power source, starts to work. Its precise control output end telescopic length is controlled. Since the electric telescopic rod 202 is stably installed on the top of the bottom plate 1 through the first support 201, the solid structure of the first support 201 ensures that the electric telescopic rod 202 will not displace or shake during operation, providing a stable support basis for the lifting action. With the telescopic extension of the output end of the electric telescopic rod 202, the connecting plate 203 fixedly connected thereto rises or falls. During the movement of the connecting plate 203, the two tooth columns 204 fixedly connected to the bottom of the connecting plate 203 play a key role. The tooth column 204 is sleeved in the sleeve 205. When the connecting plate 203 moves, the tooth column 204 slides along the inner wall of the sleeve 205. This structure effectively limits the displacement of the connecting plate 203 in the horizontal direction, making the lifting process more stable and avoiding the shaking or tilting of the work plane 5, ensuring the precision of the workpiece during processing. At the same time, the contact groove 215 opened on the outer wall of the sleeve 205 cooperates with the gear 208. The gear 208 is installed between the two second supports 206 through the rotating column 207. The second support 206 is fixed on the top of the bottom plate 1, providing a stable support and installation position for the rotating column 207. When the gear 208 rotates, its teeth mesh with the contact groove 215. At the same time that the electric telescopic rod 202 pushes the connecting plate 203 to rise or fall, the rotation of the gear 208 provides additional power for the movement of the tooth column 204, making the lifting or falling process more smooth. Moreover, the rotation speed and direction of the gear 208 can be accurately controlled through external control devices (such as motor drive, etc.), thereby adjusting the running speed and position of the lifting mechanism 2 to a certain extent, further improving the precision of the height adjustment of the work plane 5. A group of third supports 3 fixedly connected to the top of the bottom plate 1, whose top connected support panels 4 are closely related to the work plane 5. When the machine tool is processing, the work plane 5 bears the pressure from the workpiece. The support panel 4 can evenly distribute the pressure borne by the work plane 5 under the cooperation of the third support 3, preventing the work plane 5 from deforming due to uneven stress, ensuring the flatness of the work plane 5, thereby ensuring the machining precision and quality of the workpiece during processing. The whole machine tool base structure realizes the precise adjustment of the height of the work plane 5 and the stable operation of the processing process through the close cooperation of the components, meeting the diversified processing needs of numerical control machine tools.
