However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a length-adjustable machine tool worktable, including a protective box 1.

Irregularly shaped connecting plates 14 are fixedly installed on the lower ends of the two sets of worktable plates 11. A lifting mechanism 2 is provided inside the protective box 1.

[0022] The lifting mechanism 2 comprises a base 21 and a lifting platform 22, the upper end of the base 21 is fixedly installed with two groups of side plates 23, the lower end of the lifting platform 22 is fixedly installed with a tray 24, the upper end of the base 21 is fixedly installed with a servo motor 25, the output end of the servo motor 25 is fixedly installed with a shaft coupling 26, the upper end of the shaft coupling 26 is fixedly installed with a screw rod 27, the inner sides of the two groups of side plates 23 are fixedly installed with two groups of longitudinal guides 29, the outer walls of the four groups of longitudinal guides 29 are slidably installed with longitudinal sliding blocks 210, the lower end of the tray 24 is fixedly installed with two groups of connecting blocks 211, the outer wall of the screw rod 27 is threadedly connected with a threaded seat 212, the two ends of the threaded seat 212 are fixedly installed with special-shaped frames 213, the upper end of the base 21 is fixedly installed with a stable vertical seat 28, the upper and lower parts of the screw rod 27 are rotatably installed in the interiors of the two protruding parts of the stable vertical seat 28, one side of each of the four groups of special-shaped connecting plates 14 is fixed with one side of each of the four groups of transverse sliding blocks 13, the lower end of the base 21 is fixed with the inner bottom end of the protective box 1, the lifting platform 22 is located in the interior of the protective box 1, the lower ends of the two groups of connecting blocks 211 are fixed with the upper ends of the two groups of special-shaped frames 213, the protruding parts on the two sides of the two groups of special-shaped frames 213 are fixed with one side of each of the four groups of longitudinal sliding blocks 210, and the tray 24 is located above the two groups of side plates 23.

[0023] The specific settings and effects of the embodiment will be described below. By pushing the two groups of workbench plates 11 one by one, the two groups of workbench plates 11 are moved to the two sides, respectively. The two groups of workbench plates 11 drive the four groups of transverse sliding blocks 13 to move through the four groups of special-shaped connecting plates 14. The four groups of transverse sliding blocks 13 slide on the four groups of transverse sliding rails 12, respectively, so that the two groups of workbench plates 11 can be expanded outward or contracted inward. Then, the servo motor 25 is started. The output end of the servo motor 25 drives the screw rod 27 to rotate through the shaft coupling 26. The screw rod 27 rotates in the interior of the stable vertical seat 28, and at the same time, the screw rod 27 threadedly rotates in the interior of the threaded seat 212, so that the threaded seat 212 moves up and down. The threaded seat 212 drives the two groups of connecting blocks 211 and the four groups of longitudinal sliding blocks 210 to move up and down through the two groups of special-shaped frames 213. The four groups of longitudinal sliding blocks 210 slide up and down on the four groups of longitudinal guides 29, respectively. The two groups of connecting blocks 211 drive the lifting platform 22 to move up and down through the tray 24. Thus, the position of the lifting platform 22 can be adjusted. Then, the length of the machine tool workbench can be adjusted in cooperation with the two groups of workbench plates 11. The length of the machine tool workbench can be flexibly adjusted to facilitate the machining of workpieces of different lengths and prevent the machining precision of the workpieces from being affected. At the same time, the working space is not wasted, and the area of the machine tool workbench can be fully utilized.

[0024] In some production scenarios that require combined processing of multiple different length workpieces, fixed length workbenches cannot flexibly adjust the work area to adapt to the processing of different workpieces, cannot provide sufficient support length for long shafts, resulting in vibration and deformation of long shafts during processing, affecting the processing accuracy of the workpieces, while for short workpieces, it will cause waste of work space and cannot fully utilize the area of the workbench.

[0025] Under the sliding cooperation of the four groups of transverse sliding blocks 13 and the four groups of transverse sliding rails 12, the four groups of transverse sliding blocks 13 can slide on the four groups of transverse sliding rails 12 respectively, to improve the stability of the two groups of workbench plates 11 when moving;

[0026] Under the sliding cooperation of the four groups of longitudinal sliding blocks 210 and the four groups of longitudinal guide rails 29, the two groups of special-shaped frames 213 can limit the threaded seat 212, so that the threaded seat 212 moves up and down on the outer wall of the screw rod 27, while the two groups of connecting blocks 211 drive the tray 24 to move, to improve the stability of the tray 24 when moving up and down;

[0027] The two groups of side plates 23 can support the four groups of longitudinal guide rails 29, facilitating the sliding of the four groups of longitudinal sliding blocks 210 on the four groups of longitudinal guide rails 29 respectively.

[0028] Embodiment two: as shown in Figure 3 and Figure 4 The upper end of the coupling 26 is fixedly installed with a screw rod 27, and the upper end of the base 21 is fixedly installed with a stable vertical seat 28. The upper and lower parts of the screw rod 27 are rotatably installed in the interiors of the two protruding parts of the stable vertical seat 28.

[0029] The effect of the whole embodiment is that by setting the stable vertical seat 28, when the screw rod 27 rotates, the screw rod 27 will rotate in the interiors of the two protruding parts of the stable vertical seat 28, which can support the screw rod 27 to improve the stability of the screw rod 27 when rotating.

[0030] The working principle and method of using the device are as follows: first, according to the length of the workpiece, when the workpiece is long, the two sets of workbench plates 11 are moved outward, and the two sets of workbench plates 11 are moved at the upper end of the protection box 1, so that part of the two sets of workbench plates 11 is moved out of the interior of the protection box 1, when the two sets of workbench plates 11 are moved, the two sets of workbench plates 11 are respectively driven by the four sets of special-shaped frames 213 to move the four sets of transverse sliding blocks 13, so that the four sets of transverse sliding blocks 13 slide on the four sets of transverse sliding rails 12, and part of the two sets of workbench plates 11 can be stably moved out of the protection box 1, finally, the servo motor 25 is started, the output end of the servo motor 25 drives the screw rod 27 to rotate through the shaft coupling 26, so that the screw rod 27 is screwed in the interior of the threaded seat 212, the threaded seat 212 is conveniently moved upward on the outer wall of the screw rod 27, and the threaded seat 212 drives the two sets of connecting blocks 211 and the four sets of longitudinal sliding blocks 210 to move upward through the two sets of special-shaped frames 213, the four sets of longitudinal sliding blocks 210 slide upward on the four sets of longitudinal guide rails 29, and the two sets of connecting blocks 211 drive the lifting platform 22 to move upward through the tray 24, so that the lifting platform 22 is conveniently pushed to move upward, and the two ends of the lifting platform 22 are flush with one end of the two sets of workbench plates 11, so that the long workpiece is conveniently machined.
