Abstract

The invention relates to the technical field of vehicle front body treatment, in particular to a vehicle front body treatment conveying vehicle automatic locking device which comprises a rail sliding plate, a vehicle length adaptive mechanism arranged on the rail sliding plate and a lock control mechanism arranged on the vehicle length adaptive mechanism. The four groups of lockset bearing mechanisms are arranged on the track sliding plate; and the hole site locking mechanisms are arranged in each group of lockset bearing mechanism. The number of the hole site locking mechanisms is four. A rail sliding plate of a single-rail structure is arranged on a rail base of a swing rod chain, four sets of lock bearing mechanisms which are symmetrically distributed are movably installed on the rail sliding plate, and two sets of hole position locking mechanisms which are symmetrically distributed are arranged in each set of lock bearing mechanism. When the vehicle shell falls downwards and is accurately locked and fixed by the multiple sets of hole position locking mechanisms, a larger operation space can be formed between the vehicle shell and the swing rod chain, and therefore the problem that follow-up machining operation of the vehicle shell is hindered by a traditional swing rod chain clamping platform can be avoided.

Description

Technical Field

[0001] The present invention relates to the technical field of vehicle front body processing, and specifically to an automatic locking device for a vehicle front body processing conveyor vehicle. Background Art

[0002] The conveyor vehicle is an important part of vehicle front body processing. At present, the conveying devices used on the vehicle front body processing line of the automotive painting line are mainly divided into four types: friction chain, swing bar chain, RoDip, and multi-functional shuttle. During the painting process of the vehicle body, the mechanized conveying system of the vehicle body is the main artery of the painting production line, running through the entire process of the painting production line.

[0003] Currently, the most commonly used conveying device on the automotive painting line is the swing bar chain conveyor. There is no conveying mechanism directly above the tank body, and the tracks are on both sides of the upper part of the chamber body. The automotive outer shell conveyed by the swing bar chain conveyor needs to be fixed through a large-volume clamping platform. However, this platform will cause certain interference to the processing of the bottom or outer side of the automotive outer shell. At this time, the gap between the vehicle shell and the platform is relatively small, so the processing of subsequent processes will be affected by the gap and cause operational difficulties.

The anti-wear washer 564 is adapted to bear pressure on the inner wall of the vehicle outer shell 600. An internal plug 566 is arranged on the outer end guide rod of the load-bearing lock rod 561, and the outer wall of the guide rod is provided with evenly distributed slot holes. A plurality of pull rods 567 are movably installed on the inner end of the internal plug 566, a lever arm 568 is movably installed at the other end of the pull rod 567, a lock 569 is movably installed at the other end of the lever arm 568, two sliding pins 5691 are installed on the inner end shaft rod of the lock 569, and a compression spring 5692 is connected to the sliding pins 5691; The inner wall of the end cover 563 is provided with evenly distributed slots, and the sliding pins 5691 are adapted to be installed in the slots. The other end of the compression spring 5692 is fixedly connected to the end of the lining sleeve 562 penetrating into the inner cavity of the end cover 563; One end of the lock 569 away from the sliding pin 5691 is adapted to penetrate outside the slot hole; The anti-wear washer 564 is made of rubber material. The lock 569 is integrally in an L-shaped structure, and a triangular inclined plane is provided at the end of the lock 569 that penetrates through the outside of the load-bearing lock rod 561 for quickly adapting to the inner hole position of the vehicle shell 600.

[0026] Use a lifting tool to suspend the vehicle shell 600 directly above the four hole position locking mechanisms 500. Then operate the first hydraulic component 220. At this time, the hydraulic sub-rod in the first hydraulic component 220 will pull the combined first end plate 230 and the two first suspension arms 240. Finally, the two beam plates 250 will cooperate with the two sliding seats 260 to perform relative lateral movement along the chutes at both ends of the track slide plate 100, and the adjacent two lock-bearing mechanisms 400 can move relatively outward along both ends of the track slide plate 100. Finally, the four adjusted lock-bearing mechanisms 400 can cooperate with the head end and the tail end of the vehicle shell 600 for adaptation. Then operate the second hydraulic component 350. When the hydraulic sub-rod in the second hydraulic component 350 extends, the combined second end plate 340 and the two second suspension arms 330 will be pressed to push the two lead screws 310. Finally, the four positioning nuts 320 arranged on the threaded sections of the lead screws 310 can clamp the adjacent two sliding sleeves 530. After adjusting the distance between the adjacent two sliding sleeves 530 on the threaded sections of the lead screws 310, the adjacent two hole position locking mechanisms 500 can perform fine adjustment of the distance along the inner side of the protective frame 431. As the two sliding sleeves 530 are pressed, the two driven fourth suspension arms 520 will stretch the corresponding two columns 510. Finally, the fourth end plate 540 and the two traction frames 550 installed at the top of the columns 510 will contract the two symmetrically distributed lock hole assemblies 560 inward. Finally, the two symmetrically distributed lock hole assemblies 560 can clamp and fix the inner side of the vehicle shell 600 at a selected depth, so as to facilitate a larger operating space to be reserved between the fixed vehicle shell 600 and the device to avoid problems where the vehicle shell 600 is blocked during subsequent processing.

[0027] Embodiment 2: Combined with Figures 1 to 5 As shown, on the basis of Embodiment 1, the vehicle length adaptation mechanism 200 includes a clamp 210 fixedly installed on two studs in the middle of the track slide plate 100, a first hydraulic component 220 fixedly installed inside the clamp 210, a first end plate 230 installed at the bottom end of the hydraulic sub-rod in the first hydraulic component 220, two first suspension arms 240 movably installed at both ends of the first end plate 230, two beam plates 250 movably installed at the other ends of the first suspension arms 240, and a sliding seat 260 fixedly installed at the bottom of the beam plates 250. The bottom end of the sliding seat 260 is adaptively penetrated into the transverse groove inside the track slide plate 100. The two beam plates 250 are used to provide a further micro-adjustment platform for the adjacent two hole position locking mechanisms 500. An oval groove is formed on the inner side of the beam plate 250, and two oval grooves on the inner sides of the two beam plates 250 form an oval slideway.

[0028] Preferably, the fixture 210 is fixedly installed on two studs in the middle of the track skateboard 100 through two nuts. The two beam plates 250 are fixed by a combined bolt, the beam plate 250 and the sliding seat 260 are fixed by welding, and semi-circular notches for clamping the lead screw 310 are formed in two adjacent end faces of the two sliding seats 260. When it is necessary to adapt to both ends of the vehicle outer shell 600 with different lengths, by operating the first hydraulic component 220 until the internal hydraulic sub-rod contracts, the first end plate 230 installed at the bottom end of the hydraulic sub-rod and the two first suspension arms 240 will be pressed and turned upwards, and finally the two groups of beam plates 250 will push the four groups of lock bearing mechanisms 400 to expand outwards.

[0029] Embodiment 3: Combined with Figures 1 to 3 As shown, on the basis of Embodiment 1, the lock control mechanism 300 includes a second hydraulic component 350 installed horizontally in the fixture 210, a second end plate 340 installed at the outer end of the hydraulic sub-rod in the second hydraulic component 350, two second suspension arms 330 movably installed at both ends of the second end plate 340, a lead screw 310 movably installed in the inner holes of the two sliding seats 260, and four positioning nuts 320 arranged on the threaded section of the lead screw 310. The lead screw 310 and the four positioning nuts 320 are used to equally push the adjacent two groups of hole position locking mechanisms 500.

[0030] Preferably, the second hydraulic component 350 is fixed in the middle of the fixture 210 by welding. The two lead screws 310 are located directly above the track skateboard 100, and two adjacent positioning nuts 320 arranged on the threaded section of the lead screw 310 are used to lock both ends of the sliding sleeve 530. By adjusting the distance between the four positioning nuts 320 on the lead screw 310, the initial distance between the two sliding sleeves 530 can be adjusted, and finally the distance between the adjacent two groups of hole position locking mechanisms 500 can be appropriately fine-tuned.

[0031] Embodiment 4: Combined with Figure 6 and Figure 8 As shown, in the above embodiment, the hole position locking mechanism 500 further includes a traction frame 550 movably installed at the inner end of the load-bearing lock rod 561, a second spring 570 arranged outside the load-bearing lock rod 561, a fourth end plate 540 movably installed at the bottom end of the traction frame 550, a column 510 fixedly installed inside the fourth end plate 540, a fourth suspension arm 520 movably installed at the bottom end of the column 510, and a sliding sleeve 530 movably installed at the bottom end of the fourth suspension arm 520. One end of the second spring 570 is fixedly installed at the outer end of the sleeve 470, and the other end of the second spring 570 is fixedly installed on the inner wall of the inner bushing 562; The base 420 is composed of a T-shaped end tube, a rectangular cushion block and two baffles, and vertical holes for restraining the upright posts 510 are provided inside both the T-shaped end tube and the rectangular cushion block.

[0032] After the lead screw 310 cooperates with the four external positioning nuts 320 to apply a traction force to two adjacent sliding sleeves 530, the two upright posts 510 pulled by the two fourth suspensions 520 can stretch the combined fourth end plate 540 and the two traction frames 550, and the two sets of lock hole assemblies 560 distributed symmetrically will relatively extend along the inside of the sleeve 470. As the two sets of lock hole assemblies 560 continue to contract, the multiple sets of lock hole assemblies 560 evenly distributed can clamp deeper parts of the vehicle outer shell 600; By clamping and fixing the vehicle outer shell 600 at a selected height, it is possible to meet the convenience of operation and processing of the vehicle outer shell 600 on the painting line.

[0033] The working principle and usage process of the present invention: After the vehicle outer shell 600 is transported directly above the conveying device, the first hydraulic component 220 is pre-operated. As the hydraulic sub-rod in the first hydraulic component 220 extends, the first end plate 230 installed at its bottom end will push the two first suspensions 240 to extend. At the same time, the two sets of beam plates 250 and the two sets of sliding seats 260 fixed by bolts will also move outward relatively under the thrust, until two of the four sets of lock carrier mechanisms 400 move horizontally to the first-end to-be-installed part of the vehicle outer shell 600, and the other two sets of lock carrier mechanisms 400 move towards the tail-end to-be-installed part of the vehicle outer shell 600. When the four sets of lock carrier mechanisms 400 are adapted to the head and tail ends of the vehicle outer shell 600 in the suspended state, the continuous operation of the first hydraulic component 220 can be stopped; When the vehicle outer shell 600 is moved close to the four sets of lock carrier mechanisms 400 by the lifting device until the eight sets of lock hole assemblies 560 are docked with the hole positions on both sides of the vehicle outer shell 600, then the second hydraulic component 350 is operated. As the hydraulic sub-rod in the second hydraulic component 350 contracts, the second end plate 340 installed at its outer end will push the two second suspensions 330. At this time, the two evenly distributed lead screws 310 will relatively contract under the limit clamping of the two sets of sliding seats 260, and the two sets of positioning nuts 320 symmetrically distributed on the threaded sections of the lead screws 310 will apply a thrust to two adjacent sliding sleeves 530, and finally the sliding sleeves 530 will push the fourth suspensions 520 to rise; Meanwhile, the pushed column 510 and the fourth end plate 540 at its top will push the two traction frames 550 to expand outwards. Then, the two load-bearing locking rods 561 clamped by the two sleeves 470 will be pressed to insert towards the inner wall holes of the vehicle housing 600. At this time, the outer end of the anti-wear washer 564 will bear pressure on the inner wall of the vehicle housing 600, and the cushion block 565 fixed to the outer end of the load-bearing locking rod 561 will penetrate to the outside of the vehicle housing 600. And a plurality of evenly distributed locks 569 will cooperate with the extension of the load-bearing locking rod 561 to quickly insert into the holes of the vehicle housing 600 until the ends of the plurality of locks 569 penetrating to the outside of the load-bearing locking rod 561 limit and clamp the outer wall of the hole. With the second spring 570 pressing on the inner bushing 562 and the end cover 563, finally, the plurality of locks 569 and the anti-wear washer 564 can effectively clamp the inner and outer walls of the holes of the vehicle housing 600. After the vehicle housing 600 is fixed at this time, a larger operating space can be reserved to avoid the problem that the locking components of the traditional locking transport vehicle obstruct the bottom or the outside of the vehicle shell. By pre-processing fixed lock holes on both side walls of the vehicle housing 600 and combining eight groups of lock hole components 560 to fix the lock holes on the same horizontal line inside the vehicle housing 600 with the smallest area, the high suspension and low obstruction state of the vehicle housing 600 can be achieved for transportation.

[0034] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and purposes of the present invention. The scope of the present invention is defined by the claims and their equivalents.
