Description

Technical Field

[0001] The utility model relates to the technical field of lifting devices, in particular to a machine platform transport lifting device. Background Art

[0002] Automated assembly lines can effectively improve product production efficiency and reduce labor costs. Automated assembly lines often include multiple workstations, and robots are often used for transfer between multiple workstations. Taking the assembly line for stainless steel thermos cup body processing as an example, the assembly line contains three adjacent workstations, and every two adjacent workstations are set vertically. The three workstations are distributed in a T shape as a whole. The first and third workstations are set in the left and right directions, while the second workstation is set in the front and back direction. During the production process, the robot needs to transfer the product from the previous workstation to the next workstation. When the robot transfers, it also needs to move along the respective workstations. The robot on the first workstation needs to be driven by the drive assembly to move in the left and right direction, and the robot on the second workstation needs to be driven by the drive assembly to move in the front and back direction. In addition, during the transportation process, the lifting device needs to drive the manipulator to rise and fall. The lifting device currently used includes a fixed frame, a lifting frame, a lifting motor, a gear and a rack. The fixed frame is arranged inside the lifting frame, and a rack is arranged on the fixed frame. The lifting motor is connected to the gear and connected to the lifting frame. When the lifting motor is started, the lifting motor, the gear and the lifting frame rise or fall at the same time. The problem with this lifting device is that the lifting frame is larger in size than the fixed frame, and the lifting of the large lifting frame is supported by the small fixed frame. The structure is relatively unstable, the strength is poor, and the installation is not very convenient. Moreover, the lifting motor is large in size. It rises and falls with the lifting frame, and a larger lifting space needs to be reserved, which also causes inconvenience in processing and installation. Utility Model Content

[0008] As an improvement, a guide rail is connected to each of the two side walls of the lifting frame, and a slider is connected to each of the two inner walls of the fixed frame. The sliders correspond to the guide rails one by one and are slidably connected. This structure improves the stability of the sliding connection between the lifting frame and the fixed frame.

[0009] As an improvement, the cross-sections of the fixed frame and the lifting frame are both rectangular, the rack is connected to one of the side walls of the lifting frame, the other three side walls of the lifting frame are connected to a guide rail, and the three inner walls of the fixed frame are connected to a slider corresponding to the guide rail; this structure is adopted to further improve the stability of the sliding connection between the lifting frame and the fixed frame, and the overall layout is reasonable and the structure is compact.

[0010] As an improvement, a through hole is provided on the side wall of the fixing frame, an adjustment plate is connected to the outer wall of the fixing frame and the adjustment plate covers the through hole, the lifting motor is connected to the adjustment plate and the output shaft of the lifting motor extends into the installation cavity through the through hole, the gear and the lifting motor are respectively located on the inner and outer sides of the adjustment plate, and a plurality of horizontally arranged long holes are provided on the adjustment plate, and the fixing bolts pass through the long holes and are threadedly connected to the fixing frame; by adopting this structure, the position of the lifting motor can be adjusted by horizontally adjusting the position of the adjustment plate, so that the gear and the rack can be stably engaged.

[0011] As an improvement, both the gear and the rack are helical teeth; with this structure, the power transmission is more stable and the structural strength is higher.

[0012] As an improvement, there are two groups of drive components and both are connected to the turntable. The two groups of drive components are arranged horizontally and perpendicular to each other. With this structure, the turntable can drive the two groups of drive components to rotate simultaneously with one rotation, which improves the transfer efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
