[0020] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0021] It should be understood that in the description of this application, the terms "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are used solely for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. That is, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. Furthermore, unless otherwise stated, "a plurality of" means two or more.

[0022] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0023] like Figures 1-4 As shown, the lifting mechanism for the transfer device in this embodiment of the present invention includes a lifting unit 1, a connecting shaft 2, a bearing seat 3, a reducer 4, and a motor 5.

[0024] Two lifting units 1 are provided and spaced apart. The lifting unit 1 includes a base 11, a transmission assembly 12, a lead screw 13 and a nut 14. The transmission assembly 12 is located on the base 11. The lead screw 13 is vertically arranged. The lower end of the lead screw 13 is connected to the transmission assembly 12 for transmission. The nut 14 is threadedly connected to the lead screw 13.

[0025] The two ends of the connecting shaft 2 are respectively connected to the transmission components 12 of the two lifting units 1, and the connecting shaft 2 is horizontally arranged. The bearing seat 3 is installed in the middle of the connecting shaft 2. The reducer 4 is located on one side of one of the lifting units 1, and the output end of the reducer 4 is connected to the transmission component 12 of one of the lifting units 1. The motor 5 has its motor shaft connected to the input end of the reducer 4.

[0026] In use, the base 11 of the lifting unit 1 is installed on the workbench, and the nuts 14 are installed on both sides of the frame of the transfer device.

[0027] During operation, the starting motor 5 drives the reducer 4 to rotate the transmission component 12 of one lifting unit 1, thereby rotating the lead screw 13. At this time, the nut 14 moves up and down along the lead screw 13. Furthermore, through the connecting shaft 2, it drives the nut 14 of another lifting unit 1 to move up and down along the lead screw 13. In this way, the transfer device mounted on the nut 14 moves up and down, achieving position adjustment.

[0028] Based on the above structural setup, the transfer device is adjusted in position by two lifting units 1, so that the transfer device can be raised and lowered smoothly.

[0029] In this embodiment, the axial directions of the lead screw 13, the connecting shaft 2, and the motor shaft are all perpendicular to each other. This makes the overall structure compact.

[0030] like Figure 2 As shown, in some embodiments, the transmission assembly 12 includes a worm gear portion 121 and a worm wheel portion 122 that mesh with each other. The two ends of the connecting shaft 2 are respectively connected to the worm gear portions 121 of the two transmission assemblies 12, and the lower end of the lead screw 13 is mounted on the worm wheel portion 122. In this way, through the transmission of the worm gear portion 121 and the worm wheel portion 122, horizontal rotation can be converted into vertical rotation.

[0031] like Figure 1 and 2 As shown, in some embodiments, the transmission assembly 12 further includes a coupling 123, through which both ends of the connecting shaft 2 are connected to the worm gear portion 121. Thus, by using the coupling 123 to stabilize the connection structure between the connecting shaft 2 and the worm gear portion 121, motion and torque can be transmitted, providing varying degrees of axial, radial, and angular compensation performance.

[0032] like Figure 1 and 3 As shown, in some embodiments, the output end of the reducer 4 is connected to the worm gear portion 121 of a transmission assembly 12. Thus, the reducer 4 can drive the worm gear portion 121 to rotate.

[0033] like Figure 3As shown, in some embodiments, the reducer 4 is a reversing reducer. Thus, with the axial direction of the motor shaft perpendicular to the axial direction of the worm gear 121, motion and torque are transmitted through the reversing reducer.

[0034] like Figure 3 As shown, in some embodiments, the upper part of the base 11 extends horizontally to form a first mounting block 111, and the upper part of the reducer 4 has a second mounting block 41. The upper surface of the first mounting block 111 and the upper surface of the second mounting block 41 are on the same horizontal plane. This facilitates the installation of the first mounting block 111 and the second mounting block 41 on the same workbench, ensuring the stability of the operating structure of the base 11 and the reducer 4.

[0035] like Figure 3 and Figure 4 As shown, in some embodiments, the upper part of the bearing housing 3 has a third mounting block 31, and the upper surface of the third mounting block 31 is at the same horizontal plane as the upper surface of the first mounting block 111. This facilitates the installation of the third mounting block 31 and the first mounting block 111 on the same worktable, ensuring the stability of the operating structure of the base 11 and the bearing housing 3.

[0036] like Figure 1 In some embodiments, the lifting unit 1 further includes a retaining ring 15, which is fixed to the bottom outer periphery of the nut 14. Specifically, the retaining ring 15 has mounting holes, which facilitates mounting the frame of the transfer device onto the retaining ring 15.

[0037] like Figure 4 As shown, in some embodiments, the bearing housing 3 has a bearing 32, and the connecting shaft 2 is rotatably connected to the bearing 32. In this way, the bearing 32 ensures that the connecting shaft 2 can rotate stably.

[0038] like Figure 4 As shown, in some embodiments, the connecting shaft 2 has a bushing 21, through which the connecting shaft 2 is rotatably connected to the bearing 32. Thus, the bushing 21 provides support, cushioning, and reduces wear between the connecting shaft 2 and the bearing 32.

[0039] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
