Description

Technical Field

[0001] This invention relates to the field of vehicle front-end processing technology, specifically to an automatic locking device for a vehicle front-end processing and conveying vehicle. Background Technology

[0002] The conveyor is an important component in the pre-painting process. Currently, the conveyor devices used on the pre-painting process of automotive painting lines are mainly divided into four types: friction chain, swing chain, RoDip, and multi-functional shuttle. In the painting process of automotive bodies, the mechanized conveyor system of the 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 device on automotive painting lines is the swing chain conveyor. The swing chain does not have a conveying mechanism directly above the trough, and the track is on both sides of the upper part of the chamber. The car body conveyed in the swing chain conveyor needs to be fixed by a large-volume clamping platform. However, this platform will interfere with the processing of the bottom or outside of the car body. At this time, the gap between the car body and the platform is small, so the subsequent processing will be affected by the gap and cause operational difficulties.

[0004] In view of this, an automatic locking device for the front-end handling and conveying vehicle was designed to solve the above problems. Summary of the Invention

[0025] 1. This invention sets a monorail track slide on the basis of the swing arm chain track, and movably installs four sets of symmetrically distributed locking bearing mechanisms on the track slide. By setting two sets of symmetrically distributed hole locking mechanisms in each set of locking bearing mechanisms, as the car body descends until it is precisely locked and fixed by multiple sets of hole locking mechanisms, a larger operating space can be formed between the car body and the swing arm chain. This avoids the problem of subsequent processing of the car body being hindered by the traditional swing arm chain clamping platform.

[0026] 2. This invention sets four sets of symmetrically distributed locking support mechanisms at both ends of the track slide. The spacing between adjacent sets of locking support mechanisms is finely adjusted according to the complex area at the bottom of the car body. The adjacent sets of locking support mechanisms can reserve a sufficiently spacious area for the complex area at the bottom of the car body, so as to facilitate the safe operation of workers in the spacious area at the bottom of the car body, while avoiding an increase in the processing area of ​​the car body on the painting line.

[0027] 3. According to the processing depth requirements of the car body shell, the present invention selectively clamps and fixes the depth holes inside the car body shell by adjusting eight sets of locking hole components. Finally, the car body shell will be selectively locked by the spacing of the eight sets of locking hole components. At the same time, the height of the car body shell off the ground after being supported by the device can also be freely adjusted, thereby enabling the device to perform a deeper coating process on the car body shell after the selected height.

[0050] The track slide plate 100 has grooves at both ends, and transverse grooves are provided on both sides of the track slide plate 100.

[0052] The base 410 is composed of a U-shaped sliding sleeve and two arc-shaped cover plates. The inner wall of the U-shaped sliding sleeve is provided with two symmetrically distributed protruding plates, which are adapted to penetrate into two transverse grooves on both sides of the track slide plate 100.

[0053] The micro-adjustment component 430 includes a protective frame 431, a plug 440 installed on the outer end of the protective frame 431, a first spring 450 fixedly installed in the inner end slot of the plug 440, a positioning chuck 437 and a movable chuck 438 movably installed inside the protective frame 431, two third suspensions 436 movably installed on the positioning chuck 437 and the movable chuck 438, a third end plate 435 movably installed on the adjacent ends of the two third suspensions 436, two plungers 432 fixedly installed inside the protective frame 431, a screw sleeve 433 installed inside the two plungers 432, and a push screw 434 disposed inside the screw sleeve 433.

[0054] The bottom end of the push screw 434 is movably mounted inside the third end plate 435;

[0055] The hole locking mechanism 500 includes a locking hole assembly 560 disposed inside the sleeve 470, and the locking hole assembly 560 is used to insert and fix the hole in the vehicle body 600.

[0056] The lock hole assembly 560 includes a load-bearing lock rod 561 inserted into a hole in the inner wall of the vehicle body 600, a pad 565 installed on the outer end of the load-bearing lock rod 561, an inner bushing 562 disposed on the outside of the load-bearing lock rod 561, an end cap 563 installed on the outer end of the inner bushing 562, and an anti-wear washer 564 installed on the outside of the end cap 563, wherein the anti-wear washer 564 is adapted to bear pressure on the inner wall of the vehicle body 600, an inner plug 566 disposed on the outer end guide rod of the load-bearing lock rod 561, wherein the outer wall of the guide rod has evenly distributed slots, a plurality of pull rods 567 movably mounted on the inner end of the inner plug 566, a lever arm 568 movably mounted on the other end of the pull rod 567, a lock 569 movably mounted on the other end of the lever arm 568, two sliding pins 5691 mounted on the inner end shaft of the lock 569, and a compression spring 5692 connected to the sliding pins 5691;

[0057] The inner wall of the end cap 563 has evenly distributed slots, and the sliding pin 5691 is adapted to be installed in the slot, while the other end of the compression spring 5692 is fixedly connected to the end of the inner bushing 562 that extends into the inner cavity of the end cap 563.

[0058] The end of the lock 569 furthest from the sliding pin 5691 is fitted through the slot.

[0059] The anti-wear washer 564 is made of rubber material. The lock 569 has an overall L-shaped structure, and a triangular bevel is provided on the end of the lock 569 that extends to the outside of the load-bearing lock rod 561 for quick adaptation to the inner hole of the car body 600.

[0060] The car body 600 is suspended above the four sets of hole locking mechanisms 500 using a lifting device. Then, the first hydraulic component 220 is operated. At this time, the hydraulic rod inside the first hydraulic component 220 will pull the combined first end plate 230 and the two first suspensions 240. Finally, the two sets of beam plates 250 will move laterally relative to each other along the sliding grooves at both ends of the track slide plate 100 in coordination with the two sets of sliding blocks 260. The two adjacent sets of lock bearing mechanisms 400 can then be relatively extended outward along both ends of the track slide plate 100. Finally, the four sets of lock bearing mechanisms 400 after adjustment can be adapted to the front and rear ends of the car body 600.

[0061] Next, the second hydraulic component 350 is activated. When the hydraulic rod inside the second hydraulic component 350 extends, the assembled second end plate 340 and the two second suspensions 330 are compressed, pushing the two lead screws 310. Finally, the four positioning nuts 320 on the threaded sections of the lead screws 310 clamp the two adjacent sliding sleeves 530. After adjusting the distance between the two adjacent sliding sleeves 530 on the threaded sections of the lead screws 310, the two sets of adjacent hole locking mechanisms 500 can be finely adjusted along the inner side of the guard frame 431. As the two sliding sleeves 530 are compressed... Subsequently, the two fourth suspensions 520 being pulled will stretch the corresponding two pillars 510. Finally, the fourth end plate 540 installed at the top of the pillar 510 and the two traction brackets 550 will retract the two symmetrically distributed sets of locking hole assemblies 560 inward. Finally, the two symmetrically distributed sets of locking hole assemblies 560 can clamp and fix the inner side of the vehicle body 600 to a selected depth, thereby making it easier to leave a larger operating space between the fixed vehicle body 600 and the device, so as to avoid the problem of the vehicle body 600 being blocked in subsequent processing.

[0062] Example 2:

[0063] Combination Figures 1 to 5 As shown, based on 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 rod inside the first hydraulic component 220, two first suspensions 240 movably installed at both ends of the first end plate 230, two beam plates 250 movably installed at the other end of the first suspensions 240, and a slide block 260 fixedly installed at the bottom of the beam plate 250;

[0064] The bottom end of the slide 260 is adapted to penetrate into the transverse groove inside the track slide 100;

[0065] The two sets of beam plates 250 are used to provide a further micro-adjustment platform for the two adjacent sets of hole locking mechanisms 500;

[0066] The inner side of the beam plate 250 is provided with an elliptical groove, and the two elliptical grooves on the inner side of the two beam plates 250 will form an elliptical slide.

[0067] Preferably, the clamp 210 is fixedly installed on two studs in the middle of the track slide plate 100 by two nuts, the two beam plates 250 are fixed by combination bolts, and the beam plates 250 and the slide block 260 are fixed by welding. The two adjacent end faces of the two slide blocks 260 are provided with semi-circular slots for clamping the lead screw 310.

[0068] When it is necessary to adapt the two ends of the car body 600 of different lengths, the first hydraulic component 220 is operated until its internal hydraulic rod retracts. Then, the first end plate 230 and the two first suspensions 240 installed at the bottom of the hydraulic rod will be compressed and flipped up. Finally, the two sets of beam plates 250 will push the four sets of lock bearing mechanisms 400 to expand outward.

[0069] Example 3:

[0070] Combination Figures 1 to 3 As shown, based on Embodiment 1, the lock control mechanism 300 includes a second hydraulic component 350 installed in the clamp 210 and placed horizontally, a second end plate 340 installed in the second hydraulic component 350 at the outer end of the hydraulic rod, two second suspensions 330 movably installed at both ends of the second end plate 340, a lead screw 310 movably installed in the internal holes of the two slides 260, and four positioning nuts 320 provided on the threaded section of the lead screw 310.

[0071] The lead screw 310 and four positioning nuts 320 are used to push the adjacent two sets of hole locking mechanisms 500 at equal intervals.

[0072] Preferably, the second hydraulic component 350 is fixed to the middle of the clamp 210 by welding, and the two lead screws 310 are located directly above the track slide plate 100. The two adjacent positioning nuts 320 on the threaded section of the lead screws 310 are used to lock the two ends of the sliding sleeves 530. By adjusting the spacing of the four positioning nuts 320 on the lead screws 310, the initial spacing of the two sliding sleeves 530 can be controlled, and finally the spacing of the locking mechanisms 500 of the two adjacent sets of holes can be appropriately fine-tuned.

[0073] Example 4:

[0074] Combination Figure 6 and Figure 8 As shown, in the above embodiment, the hole locking mechanism 500 further includes a traction frame 550 movably installed on the inner end of the load-bearing locking rod 561, a second spring 570 disposed on the outside of the load-bearing locking rod 561, a fourth end plate 540 movably installed on the bottom end of the traction frame 550, a column 510 fixedly installed inside the fourth end plate 540, a fourth suspension 520 movably installed on the bottom end of the column 510, and a sliding sleeve 530 movably installed on the bottom end of the fourth suspension 520.

[0075] One end of the second spring 570 is fixedly installed on 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.

[0076] The base 420 consists of a T-shaped end tube, a rectangular pad, and two baffles. The interior of the T-shaped end tube and the rectangular pad are provided with vertical holes that constrain the column 510.

[0077] When the lead screw 310, in conjunction with its four external positioning nuts 320, applies traction force to the two adjacent sliding sleeves 530, the two pillars 510, which are pulled by the two fourth suspensions 520, can stretch the combined fourth end plate 540 and the two traction frames 550. The two symmetrically distributed sets of locking hole assemblies 560 will then extend relative to each other along the inside of the sleeve 470. As the two sets of locking hole assemblies 560 continue to contract, the evenly distributed sets of locking hole assemblies 560 can clamp deeper parts of the vehicle body 600.

[0078] By clamping and fixing the car body 600 at a selected height, the car body 600 can be easily operated and processed on the painting line.

[0079] The working principle and usage process of this invention are as follows: When the vehicle body 600 is transported to the top of the conveying device, the first hydraulic component 220 is pre-operated. As the hydraulic rod inside the first hydraulic component 220 extends, the first end plate 230 installed at its bottom 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 slides 260 fixed by bolts will also be pushed outward relative to each other until two sets of lock bearing mechanisms 400 move laterally to the front end of the vehicle body 600 to be installed, while the other two sets of lock bearing mechanisms 400 move towards the rear end of the vehicle body 600 to be installed. When the four sets of lock bearing mechanisms 400 are matched with the front and rear ends of the suspended vehicle body 600, the operation of the first hydraulic component 220 can be stopped.

[0080] When the vehicle body 600 is brought closer to the four sets of lock bearing mechanisms 400 by the lifting device until the eight sets of lock hole assemblies 560 are aligned with the holes on both sides of the vehicle body 600, the second hydraulic component 350 is then activated. As the hydraulic rod inside the second hydraulic component 350 retracts, 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 retract relative to each other under the limiting clamping of the two sets of slide blocks 260. The two sets of positioning nuts 320, which are set on the threaded section of the lead screw 310 and are symmetrically distributed, will apply a thrust to the two adjacent slide sleeves 530. Finally, the slide sleeves 530 will push the fourth suspension 520 to rise.

[0081] At the same time, the pushed column 510 and its top fourth end plate 540 will push the two traction frames 550 to expand outward, and the two load-bearing locking rods 561 held by the two sleeves 470 will be pressed and inserted into the holes in the inner wall of the car body 600. At this time, the outer end of the anti-wear washer 564 will be pressed against the inner wall of the car body 600, and the pad 565 fixed to the outer end of the load-bearing locking rod 561 will penetrate to the outside of the car body 600. The evenly distributed locks 569 will cooperate with the extension of the load-bearing locking rod 561 to quickly insert into the holes in the car body 600 until the ends of the multiple 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 the inner bushing 562 and the end cap 563, the multiple locks 569 and the anti-wear washer 564 can effectively clamp the inner and outer walls of the holes in the car body 600.

[0082] Once the car body 600 is fixed, a larger operating space can be reserved to avoid the problem of traditional locking conveyor components obstructing the bottom or outside of the car body. By pre-processing fixed lock holes on both sides of the car body 600, and combining eight sets of lock hole components 560 to fix the lock holes on the same horizontal line inside the car body 600 with the minimum area, the car body 600 can be transported in a state of high suspension and low obstruction.

[0083] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
