Aerial operation clamp library access device for white vehicle body welding

Abstract

The invention discloses an aerial operation clamp library access device for white vehicle body welding. The aerial operation clamp library access device for white vehicle body welding comprises a welding platform consisting of multiple uniformly arranged supporting frames, an X-directional vehicle body delivery track, a clamp positioning seat and an X-directional clamp delivery track, wherein theX-directional vehicle body delivery track, the clamp positioning seat and the X-directional clamp delivery track are arranged below the supporting frames, the supporting frames are provided with clampswitching mechanisms, each clamp switching mechanism comprises two Y-directional running guide rails arranged at the top of the corresponding supporting frame, a shear fork lifting machine capable ofsliding is supported on the two Y-directional running guide rails, a Y-directional running mechanism driving the shear fork lifting machine to slide in the Y direction is arranged between the shear fork lifting machine and the supporting frame, and the lower end of the shear fork lifting machine is provided with a clamp gripper mechanism for gripping vehicle body side clamps. The aerial operationclamp library access device adopts the design of the shear fork lifting machines and is easy to control and operate and capable of gripping vehicle clamps of heavier weights, transferring larger weight loads and controlling operation precision, and the overall stability and control precision of the aerial operation clamp library access device are improved.

Description

technical field [0001] The invention relates to the field of flexible manufacturing of body welding in automatic production of automobiles, more specifically, it relates to an air-running jig library entry and exit device for body-in-white welding. Background technique [0002] At present, the development trend of the world's automobiles is from mass production to multi-variety and small-batch production. In order to meet the extensive and diverse needs of automobile consumers and adapt to the fierce competition in the automobile market, major automobile manufacturers in the world continue to shorten the model change Cycle, to speed up the update of vehicle types, the flexible assembly is designed to adapt to this development trend, it can produce multiple models in one line, has the advantages of simple and fast production change, short development time, less secondary investment costs, production High efficiency and other advantages are widely adopted by major automobile c...

[0004] There are two main types of flexible assembly devices in the air switching mode: one is that the side wall fixture frames of different models are fixed on the aerial support frame, and the ground skid steer receives the instruction to switch models, and grabs the fixture of the next model hoisted in the air , and move to the assembly switching station to perform flexible switching of vehicle fixtures. This mechanism transfers and grabs the fixtures that need to be switched on the ground, and the aerial support frame is only responsible for fixing the side wall fixtures to be switched. After that, it is necessary to design a set of mechanism to transfer the fixture to the switching station, which increases the complexity of the mechanism and the maintenance cost is high; the second type is the transfer and grab lifting mechanism fixed on the aerial support frame , the clamp for switching models is fixed on the ground. When it is necessary to switch to the next model, the Y-direction mobile vehicle in the air moves to the storage point of the switching model fixture, grabs the fixture through the lifting and grabbing mechanism, and then moves to the switching position in the air, and places the fixture. Waiting for switching, but since the entire mechanism needs to run in the air, it will virtually increase the difficulty of the mechanism's operating accuracy and possible safety hazards. The existing lifting mechanism adopts a set of power devices (air cylinders or hydraulic cylinders) and guide columns. The power The device provides power to lift or run back and forth, and the guide column has no obvious stabilizing effect on the mechanism when lifting. This method is still easy to shake and unstable when lifting and running, and the equipment occupies a large space (height direction), which affects the height of the workshop. more demanding
