Abstract
The invention relates to a welding skid used for transferring various car bodies, comprising a ladder-shaped body, two sets of body skirt support mechanisms arranged on the ladder-shaped body, a locking block arranged on the ladder-shaped body, a car-model information code carrier and a welding-coating skid-shifting positioning hole. The welding skid is characterized in that a first group of positioning pins is symmetrically connected on the ladder-shaped body and can move between two sets of body skirt support mechanisms; and a second group of positioning pins is symmetrically connected on the ladder-shaped body and also can move on the left side of one set of body skirt support mechanism on the left part of the ladder-shaped body. The welding skid has the advantages that two groups of flexible positioning pins are adopted to guarantee the accurate positioning of the body on the skid and the transportation of the welded bodies of the car in manufacturing or to be manufactured is realized, thereby enhancing the work efficiency, largely conserving the investment and reducing the manufacturing cost.
Description
Technical field
The present invention relates to assembly plant's transloading equipment, specifically relate to a kind of welding sled that transmits multiple motorcar body, this welding skid is the transport vehicle that body in white is transferred to the application workshop from welding shop.
Background technology
In assembly plant's production process, the body in white of welding shop production need enter the application workshop according to ad hoc rules successively through the postwelding storing and transporting system.Produce the actual conditions such as structure, platform difference of car body according to motor plant, generally adopt cooresponding special-purpose skid or embrace tool as transport vehicle, promptly the corresponding a kind of welding skid of each vehicle transmits as carrier.Special-purpose skid is carried assembly such as yard body to be made up of skid body, locating dowel pin, back-up block, lock block and skid.The constructional feature of special-purpose skid is, locatees the lower body of each different automobile types, i.e. knock hole and bearing surface on the floor, front and back.Because the vehicle difference, cooresponding position of positioning hole is different, so special-purpose skid only is applicable to pairing specific vehicle.Adopt another deficiency of special-purpose skid to be: each vehicle need be provided with the skid that postwelding conveyer chain is independently just deposited the sky skid and had body in white, invest bigger, and can not repeated usage, simultaneously, because each vehicle output is unbalanced in actual production, stop up at the backhaul chain in the time of can empty skid occurring, cause stopping production situation in application workshop to take place from the backhaul of application workshop.
Summary of the invention
The objective of the invention is the defective that exists at existing special welding skid, provide a kind of simple in structure, make easily, easy to use, can be applicable to the welding sled of the multiple motorcar body of transmission.
A kind of welding sled that transmits multiple motorcar body of the present invention, comprise that ladder shape body, two is set in the upper side frame and the car body skirt support mechanisms on the following frame of ladder shape body, lock block, the vehicle information on the ladder shape body of being located at is carried a yard body, sled switching knock hole is changed in welding-application, it is characterized in that:
First group of locating dowel pin is connected on the upper side frame and following frame of ladder shape body symmetrically, and between two cover car body skirt support mechanisms, this group locating dowel pin shank is flexible locating dowel pin;
Second group of locating dowel pin is connected on the upper side frame and following frame of ladder shape body symmetrically, and is positioned at the left side of the cover of one on ladder shape body left part car body skirt support mechanisms, and this group locating dowel pin shank is flexible locating dowel pin (locating pin structure is with first group of locating dowel pin).
Described a kind of welding sled that transmits multiple motorcar body, its described ladder shape body are by upper side frame parallel to each other, following frame and be connected the left socle between upper side frame, the following frame, left medium-height trestle, right medium-height trestle and right support and form.
Described a kind of welding sled that transmits multiple motorcar body, its described lock block is located at the middle part of the right medium-height trestle of ladder shape body.
Described a kind of welding sled that transmits multiple motorcar body, its described vehicle information is carried the middle part that yard body is located at the left medium-height trestle of ladder shape body.
Described a kind of welding sled that transmits multiple motorcar body, its described welding-application change the middle part that sled switching knock hole is located at the left socle of ladder shape body.
Described a kind of welding sled that transmits multiple motorcar body, its described car body skirt support mechanisms global approximation is in " π " shape, on the upper side frame that the lower end of two perpendicular framves of this mechanism is connected to ladder shape body and the following frame, the upper end is connected with crossbearer, the length of crossbearer is respectively equipped with car body shirt rim back-up block greater than the width of ladder shape body at the two ends of crossbearer.
The present invention compared with prior art has following advantage: guaranteed car body accurate location on skid by two groups of flexible locating dowel pins, wherein, one group of locating dowel pin is with car body the location on skid of length over ends of body greater than 4200mm, another group locating dowel pin is with car body the location on skid of car body less than 4200mm, these two groups flexible locating dowel pins are realized all transmission after the welding of product and the following motorcar body that will produce, thereby improved work efficiency, reduced productive costs.
All vehicles adopt the accumulating after identical skid welds, reduced the length of empty skid accumulating district and postwelding accumulating district skid conveyer chain, this skid need not be transformed the postwelding accumulating that can be directly used in follow-up new model simultaneously, promptly can repeated usage, saved investment greatly;
When having avoided the special-purpose skid of former use because the postwelding accumulating line backhaul chain that the unbalanced production of each vehicle of welding shop occurs stops up the situation that causes stopping production takes place, thereby improved plant capacity.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, sled switching knock hole 7 is changed in the middle part welding-application that a kind of welding sled that transmits multiple motorcar body comprises that ladder shape body 1, two is set in the upper side frame 1-1 and the car body skirt support mechanisms 2 on the following frame 1-2 of ladder shape body, is located at the lock block 5 of the right medium-height trestle 1-5 of ladder shape body, the middle part vehicle information that is located at the left medium-height trestle 1-4 of ladder shape body is carried yard body 6, be located at the left socle 1-3 of ladder shape body;
First group of locating dowel pin 3 is connected on the upper side frame 1-1 and following frame 1-2 of ladder shape body 1 symmetrically, and between two cover car body skirt support mechanisms 2, this group locating dowel pin is flexible locating dowel pin;
Second group of locating dowel pin 4 is connected on the upper side frame 1-1 and following frame 1-2 of ladder shape body 1 symmetrically, and is positioned at the left side of the cover of one on ladder shape body left part car body skirt support mechanisms 2, and this group locating dowel pin is flexible locating dowel pin.Flexible pin has cylinder sleeve 4-2, spring 4-3, shank 4-1 and bottom 4-4 to constitute, and realizes Telescopic by compression spring.
