[0002] There are at least more than a dozen workstations in a painting workshop, including inspection, minor repair workstations, grinding, wax injection, etc. Each workstation needs to meet different height requirements according to different functions and usage needs.

[0003] At present, the workbench is adjusted in height through floor feet or plug-in table legs. Among them, the floor feet can only finely adjust a single table leg each time, and often there is a situation where it cannot be adjusted; while the plug-in table legs can be adjusted greatly, but the table body needs to be lifted as a whole, and lifting equipment needs to be introduced, and the operation difficulty is relatively large.

[0004] In addition, when some workbenches in use are adjusted to adapt to the operating height of the robotic arm in the later stage, since many devices have been arranged on the tabletop, the overall height adjustment of the tabletop is particularly important. However, the existing workbenches do not have this height adjustment ability, which reflects the poor convenience and poor practicability of the existing workbenches in terms of height adjustment.

Detailed Description of the Invention

[0018] In the following description, a large number of specific details are given to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some well-known technical features in the art are not described.

[0019] As Figures 1-4 shown, a workbench with adjustable tabletop height includes a pedestal 1 and a tabletop 3 installed on the pedestal 1. The pedestal 1 includes two groups of pedestal frames and connecting rod members between the two groups of pedestal frames. A height-adjusting assembly 2 is installed on each pedestal frame. The height-adjusting assemblies 2 are in transmission connection through a synchronous chain 4, and the tabletop 3 is installed at the output end of the height-adjusting assembly 2.

[0020] The utility model adds a height adjustment component 2 between the pedestal 1 and the tabletop 3, and synchronously drives the height adjustment component 2 through a synchronous chain 4, so that several height adjustment components 2 supporting the tabletop 3 output synchronously, realizing convenient height adjustment of the tabletop 3 while ensuring the stability and accuracy of the adjustment, and enabling the height adjustment structure of the workbench to stably play the height adjustment role under various working conditions.

[0021] As Figures 2-3 shown, the height adjustment component 2 includes an adjustment seat plate 21, a jacking plate 22 and a transmission unit. The adjustment seat plate 21 is installed on the seat frame, the jacking plate 22 is installed on the tabletop 3, and the transmission unit is connected between the adjustment seat plate 21 and the jacking plate 22 and is in transmission connection with the synchronous chain 4. The number of transmission units is an even number group, and the arrangement method needs to meet uniform and symmetric distribution. To ensure the effective connection between the synchronous chain 4 and the transmission unit, a tensioning gear can be installed on the adjustment seat plate 21.

[0022] Among them, the transmission unit includes a bearing 23, a transmission part 24 and a screw 25. The bearing 23 is embedded in the adjustment seat plate 21, the transmission part 24 is installed on the inner ring of the bearing 23, the screw 25 is threadedly connected to the inner side wall of the transmission part 24, the end of the screw 25 is installed on the jacking plate 22, and the outer side wall of the transmission part 24 is in a gear structure and meshes with the synchronous chain 4. The middle part of the transmission part 24 is in a threaded hole structure, and the cooperation with the screw 25 can realize the power transmission from rotational input to linear output. The external gear structure meshes with the synchronous chain 4 to obtain the original power and has high transmission accuracy, and the driving synchronization of all transmission units is good.

[0023] The height adjustment component 2 further includes a guiding unit. The guiding unit includes a sliding sleeve 26 embedded in the adjustment seat plate 21 and a sliding rod 27 slidably connected in the sliding sleeve 26. The end of the sliding rod 27 is connected to the jacking plate 22. The guiding unit can enhance the anti-deformation ability of the jacking plate 22 and reduce the risk of height adjustment operation being blocked due to excessive load on the height adjustment component 2.

[0024] Specifically, the workbench further includes a driving component. The driving component includes a driving motor and a driving gear installed at the output end of the driving motor. The driving motor is installed on the pedestal 1, and the driving gear is in transmission connection with the synchronous chain 4. If the tabletop 3 is loaded, the driving component further includes a speed change structure for increasing the output torque of the driving motor. With the output of the driving component, the height adjustment of the workbench is more convenient and labor-saving, and the adjustment speed is faster.

[0025] As Figure 4 shown, the seat frame includes a frame body 11, universal wheels 12 and floor feet 13. The frame body 11 is in a frustum-shaped frame structure. The adjustment seat plate 21 is installed on the frame body 11, and both the universal wheels 12 and the floor feet 13 are installed at the bottom of the frame body 11. The cooperation of the universal wheels 12 and the floor feet 13 facilitates the movement of the seat frame, and the floor feet 13 can level the supporting surface of the seat frame, with excellent use effects.

[0026] When the utility model is in use, first use the universal wheels 12 to transfer the workbench to the designated working station, then lock the universal wheels 12 and adjust the floor feet 13 to make the tabletop 3 horizontal. When it is necessary to adjust the height of the tabletop 3, just start the driving component. The output of the driving motor is transmitted to the transmission parts 24 of each group of transmission units through the synchronous chain 4. Under the action of the threaded connection, the rotation effect of the transmission part 24 is converted into the linear expansion and contraction of the screw rod 25, thereby realizing the output of the height adjustment component 2. When the tabletop 3 is adjusted to the target height, the driving motor can be powered off.

[0027] The preferred embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present utility model, various equivalent transformations can be made to the technical solution of the present utility model, and these equivalent transformations all belong to the protection scope of the present utility model.
