Movable supporting and positioning pin assembly of automobile body lifting appliance

Abstract

The invention discloses a movable supporting and positioning pin assembly of an automobile body lifting appliance and belongs to the field of automatic conveying devices for producing automobiles. The positioning pin assembly at least comprises a movable positioning pin mechanism, a lifting appliance arm and connection bolts, wherein the movable positioning pin mechanism is fixedly connected with the lifting appliance arm through the connection bolts; the lifting appliance arm is fixedly connected with a lifting appliance capable of bearing an automobile body through the connection bolts; one set of automobile body lifting appliance is provided with one or more groups of movable positioning pin mechanisms according to the difference of the automobile types and the process assembly requirements in order to meet the automatic switching requirements of the automatic conveying devices under the ordinary state in which a plurality of types of automobiles are produced in the same line under a plurality of platforms in the production process of the automobiles. According to the movable supporting and positioning pin assembly of the automobile body lifting appliance, when a rotary supporting and positioning pin is pushed to rotate around a rotating shaft to the required position of the automobile type, a rotary fixed pin is inserted into a defined rotary fixed pin connection hole and is locked; the movable supporting and positioning pin assembly is capable of performing positioning quickly, carrying out adjusting accurately and flexibly, and implementing the function of switching the position of the supporting and positioning pin of the automobile body lifting appliance.

Description

technical field [0001] The invention relates to the field of automatic conveying equipment for automobile production, in particular to a movable support positioning pin assembly of a vehicle body hanger. Background technique [0002] Automated conveying equipment for automobile production is widely used in automobile manufacturing plants. During the production process of automobiles, corresponding spreaders need to be used to carry the car body for continuous transfer. In order to meet the automatic transfer requirements of automated conveying equipment, the spreader generally uses a set of fixed supports The pins are used to position and support the process holes of the body bottom plate to ensure the position consistency of the body on the spreader and improve the success rate of automatic transfer. [0003] However, with the development of society and economy, automobile manufacturers continue to develop new models in order to meet market demand. At the same time, in orde...

Problems solved by technology

[0005] A set of fixed support pins is usually used for the spreader of automobile production and conveying equipment. Since the process holes of the underbody of multiple models cannot guarantee the consistency of size and position, the only set of fixed support pins on the spreader will not be able to meet the mixed production of multiple models. demand, poor versatility

Before each new model goes online, it is necessary to modify the key parts of the automatic conveying equipment, such as the spreader, until the new spreader meets the production requirements of the new model. However, the transformation and new construction will not only increase the investment, but also reduce the equipment utilization rate of the existing production line , and prolong the launch cycle of new models, reducing the market competitiveness of new models
