Clamping device and hoisting system

Abstract

The invention discloses a clamping device and a hoisting system. The clamping device comprises a support mechanism, a clamping mechanism and a linkage mechanism, wherein the support mechanism comprises a first support; the clamping mechanism comprises gripper units, and at least two gripper units are arranged; the linkage mechanism comprises a telescopic rod and a linkage assembly, wherein the linkage assembly is movably connected between the telescopic rod and the gripper units; the telescopic rod can telescopically move on the first support, and the telescopic rod telescopically moves, so that the linkage assembly drives the gripper units to be folded or unfolded; and the hoisting system comprises a hoisting device and the clamping device. When an object such as a vehicle body panel is clamped, the telescopic rod drives the linkage assembly to move through stretching and contracting the telescopic rod, and then the linkage assembly drives at least two gripper units to move so as to enable the gripper units to be matched to firmly grasp the object, so that the grabbing action on the object is realized; and compared with the lifting mode through a flexible chain, the stretching andcontracting of the telescopic rod has a limiting function, so that the object can be prevented from tilting or rotating to swing during grabbing, the stretching and contrcting of the telescopic rod can be operated by a single person, and the production efficiency is higher.

Description

technical field [0001] The invention relates to the technical field of vehicle assembly, in particular to a clamping device and a hoisting system. Background technique [0002] The body-in-white welding line of the automobile main engine factory is often arranged with multiple manual loading and unloading positions, such as the front floor, rear floor, longitudinal beam frame, engine room and other large panels or station parts transfer of sub-assemblies. Such body panels are large in size (about 1.5m in length and width) and heavy in weight (about 30kg-50kg). OEMs usually need to set up power-assisted lifting mechanisms such as lifting hoists to assist assemblers in handling operations. The general structure is that flexible steel chains and hooks are used to hook the body panels, and the body panels are hoisted in place by lifting hoists. [0003] However, this hoisting operation has the following defects: 1. Due to the large size and weight of the body panels, the use of...

Problems solved by technology

[0003] However, this hoisting operation has the following defects: 1. Due to the large size and weight of the body panels, the use of chains and hooks can easily cause the workpiece to tilt or rotate, resulting in unstable positions of the body panels during hoisting and high safety risks , and it is difficult to align the parts when placing the parts, and the assembly is inconvenient; second, it usually requires at least two people to operate at the same time, the labor intensity is high, the labor cost is high, and the efficiency of loading and unloading parts is low; The position of the hanging hole is deformed after being stressed, which affects the structural accuracy and assembly quality of the body panel
