Description

Carry the driver train of vehicle body skid

Technical field

The utility model relates to the skid delivery system, especially relates to a kind of driver train for delivery of the vehicle body skid.

Background technology

Along with the development of the modernization of industry, also more and more higher to the requirement of delivery system.In the industries such as Automobile manufacturing, usually adopt on its manufacturing line that the slide-type conveyer carries out application, general assembly, the production process such as be welded, carry that the prying body of object relies on that the friction force of idler pulley or chain is realized advancing, retreated, translation, lifting, accumulate and the function such as rotation.But because the automotive development cycle is shorter and shorter, updating of manufacturing process requires auto production line is transformed frequently, and adopts at present the mode of board-like conveying and chain conveying, and the flexibility transformation of manufacturing line and production capacity Promotion Transformation are all comparatively difficult.

Chinese patent Granted publication number: CN 201990179U, September 28 2011 Granted publication day, a kind of light skid-mounted conveying device is disclosed, drive assembly by coupler and axle drive shaft load, axle drive shaft drives the chain transmission, axle drive shaft is arranged on organism frame, the chain guide track is fixed on the organism frame inboard, organism frame is connected with base for supporting, guiding rail is arranged on outside organism frame, the sprocket wheel load of chain stretching device and chain, the switch track is arranged on the organism frame end, inductive switch can move on the switch track, the first inductive switch fixed support is fixed on a side of organism frame, the first inductive switch is fixed on the first inductive switch fixed support, the second inductive switch fixed support is fixed on a side of organism frame and near the other end of the organism frame at second switch track place, the 3rd inductive switch is fixed on the second inductive switch fixed support.Weak point is, drive motor drives drive shaft turns, promotes sprocket wheel and chain gear on whole production line, and in the time of transforming manufacturing line, the improvement of manufacturing line difficulty is larger, and the cost of transformation improves greatly, therefore can't adapt to flexible manufacturing process.

The utility model content

The utility model is to adopt the chain type skid-mounted conveying device to cause the larger deficiency of improvement of manufacturing line difficulty in order to overcome existing manufacturing line, provide a kind of and can realize that the vehicle body conveying is simultaneously comparatively convenient and swift for improvement of manufacturing line by the prying body bar, can adapt to the driver train of the conveying vehicle body skid of flexible manufacturing process.

To achieve these goals, the utility model is by the following technical solutions:

a kind of driver train of carrying the vehicle body skid of the present utility model, comprise and drive pedestal and some columns for the support drive pedestal, described driving pedestal upper surface is provided with stay bearing plate, described stay bearing plate one end is captiveed joint with the driving pedestal with rotating shaft by back-up block, the other end is fixed with actuating device, described actuating device comprises drive motor, the active rotating shaft that is connected with drive motor and be arranged on driving wheel on active rotating shaft, the driver train of described conveying vehicle body skid also comprises hunting gear, described hunting gear comprises swing arm plate and the flower wheel corresponding with driving wheel, described swing arm plate is arranged on stay bearing plate and with rotating shaft and is flexibly connected, described flower wheel is arranged on swing arm plate one end by driven shaft, be provided with the prying body bar for delivery of object between described driving wheel and flower wheel, be provided with spring return function mechanism between described swing arm plate and stay bearing plate.When the prying body bar entered between driving wheel and flower wheel, flower wheel strutted laterally, and the swing arm plate also swings under the drive of flower wheel laterally, and this moment, spring return function mechanism shrank, and the prying body bar relies on friction force to be fed forward; When the prying body bar leaves driving wheel and flower wheel, when entering next driver train, flower wheel stops operating gradually, and the plate of swing arm simultaneously inwardly swings under the effect of spring return function mechanism and gets back to original position, realizes that so skid and the vehicle body on the prying body bar carried.Due to separate between each conveying mechanism, in the time of need to transforming manufacturing line, only need dismantle to remove and install and add conveying mechanism and can complete transformation, transformation is got up more for convenience.

As preferably, described spring return function mechanism comprises at least one spring, and described spring one end connects stay bearing plate, and the described spring other end is connected with push rod, and the described push rod other end is captiveed joint with the swing arm plate.When the prying body bar enters between driving wheel and flower wheel, spring return function mechanism is compressed, makes flower wheel compress the prying body bar by the swing arm plate, makes between driving wheel, flower wheel and prying body bar and produces friction force, when the prying body bar leaves between driving wheel and flower wheel, can make flower wheel and the timely return of swing arm plate.

As preferably, the minor increment between described driving wheel and flower wheel is less than the width of prying body bar.When the prying body bar enters between driving wheel and flower wheel, can guarantee that spring return function mechanism can be compressed, thereby make flower wheel can compress the prying body bar.

As preferably, the swing arm plate is provided with flower wheel one end and is provided with postive stop baffle towards a side of driving wheel.Postive stop baffle is used for the minimum spacing between restriction driving wheel and flower wheel, contacts with driving wheel when avoiding the flower wheel return and unnecessary wearing and tearing occur.

As preferably, the prying body boom end is provided with inclined-plane or arc surface near flower wheel one side.At first the prying body bar can touch driving wheel near the side of driving wheel like this, and flower wheel swing process laterally is comparatively level and smooth, guarantees that the prying body bar can enter between driving wheel and flower wheel smoothly.

As preferably, the diameter of driving wheel is greater than the diameter of flower wheel.The driving wheel diameter is larger, and the contact surface of prying body bar is larger, guarantees the stability that the prying body bar slides.

Therefore, the utlity model has following beneficial effect: (1) promotes the prying body bar by the friction between driven wheel and prying body bar and travels forward, and works comparatively smooth-going stable, impacts less; (2) separate between each driver train on manufacturing line, therefore conveniently it to be arranged, the improvement of manufacturing line at place is comparatively convenient, flexible.
