A kind of vehicle body is always spelled the prepackage conveying device
The utility model belongs to the auto production line field, and the prepackage transportation art in referring to that vehicle body is total and spelling refers to that a kind of vehicle body always spells the prepackage conveying device especially.
Welding (take car as example) for automobile body-in-white, all generally progressively to be welded by stamping parts → little assembly → sub-unit → body assembly, and especially important always to spell station (floor, gusset being merged to the welding sequence of formation body frame) in this process.Existing Welding Process Design has two schemes usually: scheme one, realized by a station: after floor is carried and put in place, by Automatic hook block (or robot), be placed on fixture by gusset and the location clamping, improve the rear welding of two be merged.Scheme two, by two stations, realized: a rear station carries out two pre-splicing, and is connected (preventing that workpiece breaks away from course of conveying) with the prepackage hasp, after then being transported to previous station, then completes the location clamping by fixture.
The concrete technical scheme of scheme one is that as shown in Figure 1, this scheme is comprised of following 5 mechanisms: floor positioning and clamping mechanism 1, slide unit base 2, slide unit 3, left-side positioning and clamping mechanism 4(can be turned into level by 90 degree, for fitting, guide rail is arranged at bottom, but horizontal slip),, right side wall positioning and clamping mechanism 5(can be turned into level by 90 degree, for fitting, guide rail is arranged at bottom, but horizontal slip).
After floor is transported to this station by the reciprocating lever conveying mechanism, the left and right gusset is transported to (being now level) on positioning and clamping mechanism 4 and 5 by Automatic hook block respectively, after location clamps, mechanism 4 and 5 turns over and turn 90 degrees, become vertical state (state shown in Fig. 1), slide unit 3 moves to the inside, is merged the rear welding that puts in place.
This kind of scheme not only has horizontal direction to move, and also has flip-flop movement, and structure is comparatively complicated, the later maintenance difficulty, and frock and maintenance cost are all very high.And because the complexity of mechanism causes the accessibility of solder joint bad, the welding difficulty, production efficiency is lower.
The concrete technical scheme of scheme two is, this scheme is realized by two stations: a rear station is provided with simple sliding table mechanism, is clamped after manually workpiece being in place, and is connected with the prepackage hasp, realize the pre-splicing of workpiece, break away from course of conveying to prevent workpiece; Be transported to previous station after pre-splicing completing, the fine positioning slipway mechanism slides to the inside, again gusset is positioned and clamp operation.
Although this scheme has been simplified much in the mechanism of frock, as has reduced switching mechanism, frame structure becomes simply, and the solder joint accessibility is improved.But, due to the mode that has adopted the prepackage hasp to connect, cause die cost, the reduction of raising stock utilization, the increase of operating personnel's amount of labour, operating efficiency to reduce.
The utility model content

The specific embodiment
Below describe the technical solution of the utility model in detail by specific embodiment, should be understood that, following embodiment is only exemplary, only can be used for explaining and the explanation the technical solution of the utility model, and can not to be interpreted as is the restriction to technical solutions of the utility model.
A kind of vehicle body is always spelled the prepackage conveying device, includes base 15, cylinder A mount pad 14, cylinder B mount pad (not shown), cylinder A13, cylinder B16, slide plate 12, cylinder engaging lug 11, positioning support fagging 6, locating piece 7 and 17, limited block 8, slide rail mount pad 9 and slide rail 10; Base 15 is connected with the reciprocating lever induction system, and base only plays and connects and supporting role.
Base 15 upper surfaces are provided with cylinder A mount pad 14, cylinder B mount pad; Cylinder A13 mono-end connects cylinder A mount pad 14, and the other end is connected with cylinder engaging lug 11, and slide plate 12 1 ends and cylinder engaging lug 11 are fixing and be fixed with positioning support fagging 6, by stretching of cylinder A, drive slide plate and positioning support fagging reciprocating.
Slide rail mount pad 9 is installed on base 15 and between cylinder A mount pad 14 and cylinder B mount pad; Cylinder B16 mono-end is fixed on cylinder B mount pad, and the other end is connected with slide rail 10, and an end of slide rail 10 is fixed with positioning support fagging 6; Slide rail 10 matches with slide rail base 9, and locating piece 7 and 17 is fixed on slide rail mount pad 9, on locating piece 7 and 17, slide plate 12 and slide rail 10, is fixed with respectively limited block 8.The two ends that fixing positioning support fagging and limited block lay respectively at slide plate on slide plate; The two ends that fixing positioning support fagging and limited block lay respectively at slide plate on slide rail.

Application principle of the present utility model:
Below how explanation utilizes the technical solution of the utility model to complete location and the conveying of workpiece.As shown in Figure 3, this device is two one group use to the application state of the technical program, is supported on respectively the front and rear portions of workpiece, and base 1 bottom of device is connected on the reciprocating lever conveying mechanism, thereby realizes the conveying of workpiece between two stations.Below introduce the concrete implementation step of this device:
The first step: the preparation of workpiece.At a rear station, after floor is in place, provided with simple sliding table mechanism coarse positioning gusset, then slide unit slips into, and gusset and floor are merged and put in place.
Second step: the location of workpiece, support.After workpiece has been merged, the positioning support fagging of this device is protruding under the promotion of cylinder A13 and cylinder B16, and then conveying mechanism rises overally, thereby realizes floor and gusset 20 are located simultaneously, supported.
The 3rd step: the conveying of workpiece.After workpiece is positioned, supports, conveying mechanism continues to rise, and makes whole workpiece break away from fixture, and after rising puts in place, conveying mechanism is fed forward a station under drive motors drives, and workpiece is transported to next station.
The 4th step: workpiece falls, and conveying mechanism returns.After workpiece is transported to previous station, conveying mechanism descends, and workpiece is fallen on the positioning fixture of floor, and this device is realized breaking away from fully with workpiece.The positioning support fagging is inwardly retracted under the promotion of cylinder A and cylinder B, and then conveying mechanism returns.
The 5th step: workpiece fine positioning.After conveying mechanism returns, the fine positioning slipway mechanism of both sides inwardly slides, and again gusset is positioned and clamps, and then robot can carry out welding operation.
