Abstract
The utility model relates to a pushing tool, in particular to a one-way pushing device. The one-way pushing device comprises a moving trolley and a pushing device body connected with the moving trolley. The one-way pushing device is characterized in that the pushing device body comprises a push rod and a return spring connected with the push rod, and the push rod is fixedly connected with the moving trolley through a rotating bearing. The one-way pushing device has the advantages of being simple in structure, convenient to operate, long in service life and convenient to manufacture.
Description
Technical field
The utility model relates to a kind of promotion frock, especially relates to a kind of unidirectional thrust unit.
Background technology
As everyone knows, Automobile manufacturing four big subsidiary factory stamping factories, the factory that is welded, application factory, general assembly factory, wherein there are three big subsidiary factories to adopt the free parking type conveyer chain to drag suspender, vehicle body and car load are long-pending to be put in order to transmit each other, because the relative manufacturing line speed of free parking type conveyer chain is slower, the suspender beat does not satisfy the manufacturing line beat, and therefore a last procedure occurs waiting for stagnation behavior, have a strong impact on production task.Unidirectional thrust unit claims car puller again as its name suggests, promote a kind of device that suspender or loading dolly move ahead automatically by a direction exactly, the car puller type of drive has air-cylinder type at present, the driven by motor belt-type, the driven by motor chain-type, yet existing pusher gear is diversified in specifications, do not pass through fine limit work, integral structure, all connecting portions adopt the covered arc welding welding, be of rude workmanship, fault is frequent, and there is not accessory to change after damaging, in case each damage of components will cause the whole production linear velocity to slow down, suspender can't be pushed in the elevator automatically, and what replace will be manually suspender to be pushed into the elevator zone, causes the increase of fix the number of workers waste and labour intensity.
Summary of the invention
The utility model mainly is at the above-mentioned technical matters of existing in prior technology, and a kind of simple in structure, easy to operate, long service life, the easy unidirectional thrust unit of manufacturing are provided.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: a kind of unidirectional thrust unit, comprise the thrust unit that travelling car and travelling car connect, it is characterized in that described thrust unit comprises push rod and the retracing spring that links to each other with push rod, captive joint by swivel bearing between described push rod and the travelling car.Stretched wire speed that the utility model structure has mainly solved suspender when closing on the elevator section does not slowly catch up with, productive temp is slow, and suspender arrives the problem that the pause last process is stagnated after the elevator locations, has directly promoted the work tempo of manufacturing line.The utility model has shielded the existing a series of shortcomings of original car puller, and component structural is re-constructed, and processing be made into the standard fitting that spare part can be changed, and has increased several times than existing car puller service life of the present utility model again.
As preferably, be connected by bolt of rear end plate between described swivel bearing and the push rod.The utility model adopts the tapering bearing, is characterized in holding capacity greater than ball bearing of main shaft, has replaced the ball bearing of main shaft of former car puller, has increased service life, and retracing spring changes gauge member into by original nonstandard, changes quick and convenient.Track and the equal selection standard spare of travelling car fitness make operational process more steady.
As preferably, described retracing spring is arranged on push rod and travelling car junction.This equipment mechanism can be complementary with structures such as cylinder, motor driving chains, promotes utensils such as suspender, technology dolly and arrives assigned address fast, thereby satisfy the manufacturing line productive temp.Stretched wire speed that this apparatus structure has mainly solved suspender when closing on the elevator section does not slowly catch up with, productive temp is slow, and suspender arrives the problem that the pause last process is stagnated after the elevator locations, has directly promoted the work tempo of manufacturing line.
As preferably, described travelling car is provided with the roller of several symmetrical distributions.The travelling car that is provided with roller can allow car puller move back and forth along track, and the use that can match with cylinder, chain of this device has solved the often problem of distortion of the unstable push rod that causes of original car puller operation.
Therefore, the utlity model has characteristics such as simple in structure, easy to operate, long service life, manufacturing be easy.
Description of drawings
Accompanying drawing 1 is a kind of structural upright scheme drawing of the present utility model.
The specific embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1:
Shown in Figure of description 1, a kind of unidirectional thrust unit, comprise the thrust unit that travelling car 1 and travelling car connect, captive joint by swivel bearing 4 between the retracing spring 3 that thrust unit comprises push rod 2 and links to each other with push rod, push rod 2 and travelling car 1.Be connected by bolt of rear end plate 5 between swivel bearing 4 and the push rod 2.Retracing spring 3 is arranged on push rod 2 and travelling car 1 junction.Travelling car is provided with the roller 6 of four symmetrical distributions.
When installing and using, when suspender travels to the elevator zone, the suspender number of sending out bar is run into location switch, location switch signals to car puller cylinder or motor, motor or cylinder drive this device and move ahead, because this device has unidirectional impetus, is unlikely to the car puller push rod and is suspended to dolly when cylinder returns.
Should be understood that this embodiment only is used for explanation the utility model and is not used in the scope of the present utility model that limits.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
