Automobile model switching mechanism of automobile production line

Abstract

The invention relates to an automobile model switching mechanism of an automobile production line, and solves the defect that in the prior art, one welding clamp only can correspond to one automobile model, so that the automobile model switching is inconvenient, the switching operation is troublesome and disordered, and the work efficiency is low. The automobile model switching mechanism comprises a rotating platform, at least two sets of clamping and positioning mechanisms on the rotating platform, and a rotary driving mechanism fixed under the rotating platform, wherein the clamping and positioning mechanisms comprise frame bodies, clamping arms, positioning arms and driving units; the clamping arms and the positioning arms are hinged to the frame bodies; the driving units correspond to the clamping arms and the positioning arms respectively; and the rotary driving mechanism comprises a rotating shaft and a driving gear meshed with outer teeth of the rotating shaft. As the clamping and positioning mechanisms are arranged on the rotating platform, and the lower part of the rotating platform is arranged on the production line, one set of rails is shared, and the rotary driving mechanism drives the rotating platform to rotate, the fast switching between two or three sets of the clamping and positioning mechanisms on the rotating platform is realized, the efficiency is high, the structure is simple, no transfer rail is required to be arranged additionally, and the cost is reduced.

Description

technical field [0001] The invention relates to a clamping component on an automobile production line, in particular to a vehicle model switching mechanism capable of switching clamping between different vehicle models. Background technique [0002] With the rapid development of automobile manufacturing technology, the design of welding fixtures plays an increasingly important role in the production of automobile body-in-white. In the automobile production line, generally only one welding jig is set at one station, especially in the traditional production process, it is also customary to complete the welding of a car body at one station and then transfer it to the next station Or transfer to a fixed-point storage area, and then transfer the next body to this station for welding, or a fixture always corresponds to a body, and always follows this body during the circulation process on the production line. But this requires a large number of fixtures. If there are many types o...
