At the same time, when the vehicle parts need to be sprayed, they are lowered to adapt to the spraying position.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0021] Figure 1 This is a schematic structural diagram of a vehicle painting hoisting and conveying device, such as Figure 1 As shown, and refer to Figures 2 to 4 The embodiment of the present invention provides a vehicle painting hoisting and conveying device, which includes a ring conveyor line, a spraying room and a plurality of suspension mechanisms. The spraying room is arranged at a preset position of the ring conveyor line. The plurality of suspension mechanisms are evenly arranged along the ring conveyor line. The suspension mechanism includes a limit part 100, a lifting frame 200, a connecting cylinder 300, a plurality of suspension clamps, an equidistant motion component 500 and a linkage component.

[0022] The limiting part 100 is installed on the circular conveyor line. The lifting frame 200 is located below the limiting part 100. The lifting frame 200 and the limiting part 100 are connected by a connecting cylinder 300. The connecting cylinder 300 is a telescopic cylinder to drive the lifting frame 200 to rise and fall. The upper end of the suspension clamp is connected to the lifting frame 200 in a horizontal sliding direction. The equidistant motion component 500 is connected to multiple suspension clamps in sequence, and is used to drive all other suspension clamps to move closer or farther from each other when one suspension clamp slides on the lifting frame 200; the linkage component is connected to a suspension clamp, and is used to drive the suspension clamp to slide when the lifting frame 200 rises or falls relative to the limiting part 100.

[0023] Specifically, the spraying room is used to spray vehicle parts. The limiting part 100 moves under the drive of the circular conveyor line. Further, the connecting cylinder 300 is extended and retracted by adjusting the air pressure, thereby changing the distance between the lifting frame 200 and the limiting part 100 to drive the lifting frame 200 to rise or fall. The rise and fall of the lifting frame 200 can change the distance between the hanging clamp and the limiting part 100, thereby changing the distance between the vehicle parts clamped by the hanging clamp and the limiting part 100. When the position of the vehicle parts is low, the distance between the center of gravity of the vehicle parts and the limiting part 100 is large, so during the movement of the limiting part, the stability of the vehicle parts on the hanging clamp is poor. Therefore, the adjustable distance between the lifting frame 200 and the limiting part 100 can lift the vehicle parts to increase the stability of the conveying when the vehicle parts are conveyed forward by the circular conveyor line, thereby preventing the vehicle parts from shaking and causing collisions, thereby ensuring the quality of the vehicle parts. At the same time, when the vehicle parts need to be sprayed, they are lowered to adapt to the spraying position.

[0024] Furthermore, the isometric motion assembly 500 can drive the multiple suspension clamps to separate and approach synchronously. When the multiple suspension clamps are separated from each other by a larger distance, it is convenient to spray the surface of the vehicle parts, thereby improving the processing quality of the vehicle parts. When the multiple suspension clamps are approached and the distance is reduced, the overall center of gravity of the suspension mechanism can be concentrated, further increasing the stability of the vehicle parts during the transportation process.

[0025] During operation, the vehicle parts are hung on the hanging clamps. In the initial state, the lifting frame 200 is in a high position. The circular conveyor line drives the hanging mechanism to move forward. When the hanging mechanism moves to the spray room, the connecting cylinder 300 extends to cause the lifting frame 200 to move downward to a preset height. At the same time, when the lifting frame 200 moves downward, the linkage assembly drives the multiple hanging clamps away from each other through the isometric motion assembly 500, so that the distance between two adjacent hanging clamps increases. When the lifting frame 200 stops moving, the relevant equipment in the spray room sprays the vehicle parts. After the spraying operation is completed, the connecting cylinder 300 restores its length to drive the lifting frame 200 to rise. At the same time, the linkage assembly drives the multiple hanging clamps to move closer to each other through the isometric motion assembly 500 until they return to the initial state.

[0026] In some embodiments of the present invention, Figure 1 and Figure 4 As shown, the lifting frame 200 includes two lifting blocks 210 and a sliding rail 220. The lifting blocks 210 are connected to the limiting part 100 through a lifting cylinder, and the sliding rail 220 is horizontally arranged, and the two ends of the sliding rail are respectively fixed to the two lifting blocks 210. The suspension clamp includes a slider 410 and a clamping claw 420, the slider 410 is slidably arranged on the lifting rail, and the clamping claw 420 is installed on the slider 410.

[0027] Specifically, the sliding track 220 is composed of two track rods, and the slider 410 is slidably mounted on the two track rods. Further, there are multiple connecting cylinders 300, which are vertically arranged on the lifting block 210, and the upper ends are connected to the limiting part 100.

[0028] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the plurality of sliders 410 include a first slider 411 and a plurality of second sliders 412. The linkage assembly is connected to the first slider 411, and the linkage assembly is used to drive the first slider 411 to slide when the lifting block 210 rises or falls. The equidistant assembly includes a plurality of driven connecting rods 520 and two active connecting rods 510.

[0029] The middle of each driven link 520 is rotatably connected to a second slider 412, and two adjacent driven links 520 are rotatably connected to each other. The two active links 510 are rotatably connected to the driven links 520 at both ends, respectively, and one active link 510 is rotatably connected to the first slider 411, and the other active link 510 is rotatably connected to the lifting block 210.

[0030] Specifically, the positions of the rotational connection are all rotationally connected by means of an axis hinge. Further, the length of the active connecting rod 510 is equal to half the length of the driven connecting rod 520, so that the slider 410 can move equidistantly. Further, the setting of the rotational connection between an active connecting rod 510 and a lifting block 210 can make the mechanism composed of the active connecting rod 510 and the driven connecting rod 520 extend or contract under the drive of the first slider 411.

[0031] In some embodiments of the present invention, Figure 2 and Figure 4 As shown, the linkage assembly includes a linkage screw rod 610 and a driving unit 620. The linkage screw rod 610 is arranged in parallel with the sliding track 220 and is rotatably inserted into the two lifting blocks 210. The linkage screw rod 610 passes through the first slider 411 and the second slider 412 in sequence, and the first slider 411 is threadedly connected to the linkage screw rod 610. The driving unit 620 is used to drive the linkage screw rod 610 to rotate in a first rotation direction when the lifting block 210 rises. When the lifting block 210 descends, the linkage screw rod 610 is driven to rotate in a second rotation direction, and the first rotation direction and the second rotation direction are opposite directions to each other.

[0032] Specifically, a threaded hole is provided on the first slider 411, and a through hole is provided on the second slider 412, and the diameter of the through hole is greater than the diameter of the linkage screw 610. Further, the first slider 411 forms a screw nut mechanism with the linkage screw 610 through the threaded hole, and the first slider 411 is driven by the linkage screw 610 to slide, which can increase the stability of the sliding, thereby preventing the automobile parts from shaking when the slider 410 slides. Specifically, when the linkage screw 610 rotates in the first rotation direction, the first slider 411 slides in the direction of the second slider 412, and drives the multiple sliders 410 to approach each other through the active connecting rod 510 and the driven connecting rod 520. When the linkage screw 610 rotates in the second rotation direction, the first slider 411 slides in the direction away from the second slider 412, and the first slider 411 drives the multiple sliders 410 to move away from each other through the active connecting rod 510 and the driven connecting rod 520.

[0033] In some embodiments of the present invention, Figure 1 and Figure 4 As shown, the driving part 620 includes a linkage rack 621 and a linkage gear 622. One end of the linkage screw rod 610 extends outward from the lifting block 210. The linkage gear 622 is fixedly sleeved on one end of the linkage screw rod 610, and the linkage rack 621 is vertically arranged, and the upper end is fixedly connected to the limit part 100; the linkage rack 621 is meshed with the linkage gear 622.

[0034] Specifically, since the linkage rack 621 and the linkage gear 622 are meshed, when the lifting block 210 descends, the linkage gear 622 rotates in the second rotation direction under the action of the linkage rack 621, thereby driving the linkage screw 610 to rotate in the second rotation direction. When the lifting block 210 ascends, the linkage gear 622 rotates in the first rotation direction under the action of the linkage rack 621, thereby driving the linkage screw 610 to rotate in the first rotation direction.

[0035] In some embodiments of the present invention, Figure 3 As shown, the clamping jaw 420 includes two first clamping rods 421 and two second clamping rods 422. The upper ends of the first clamping rods 421 are rotatably connected to the slider 410, and the rotation axes of the two first clamping rods 421 on the slider 410 are coaxial. The middle parts of the two second clamping rods 422 are rotatably connected, and the upper end of each second clamping rod 422 is rotatably connected to the lower end of a first clamping rod 421, and a hook 423 extends from the lower end of the second clamping rod 422.

[0036] Specifically, the two first clamping rods 421 and the two second clamping rods 422 constitute a scissor mechanism. When the angle of the two first clamping rods 421 increases, the angle between the two second clamping rods 422 increases synchronously. Further, when there is a heavy object on the hook 423, the second clamping rod 422 rotates toward a vertical state under the action of gravity, causing the angle between the two second clamping rods 422 to decrease until the two second clamping rods 422 clamp the heavy object. However, since the second clamping rod 422 still has a tendency to rotate in a vertical direction under the action of the heavy object, the two second clamping rods 422 apply a clamping force to the heavy object, that is, the heavier the clamped component, the tighter the clamping force of the two second clamping rods 422 on the heavy object.

[0037] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, the suspension clamp further includes a rotating block 430. The rotating block 430 is rotatably disposed below the slider 410. The clamping jaw 420 is mounted on the rotating block 430 so as to drive the clamping jaw 420 to rotate synchronously when the rotating block 430 rotates. The suspension mechanism further includes a turning assembly, which is used to drive the plurality of rotating blocks 430 to rotate synchronously when the slider 410 slides.

[0038] Specifically, the turning assembly includes a turning rack 710 and a plurality of turning gears 720 . Each turning gear 720 is fixedly mounted on a rotating block 430 . The turning rack 710 is horizontally arranged, and its two ends are respectively fixedly connected to two lifting blocks 210 . The turning gear 720 is combined with the turning rack 710 .

[0039] Specifically, when the slider 410 slides, the rotating block 430 rotates under the action of the rotating gear 720 and the rotating rack 710, so that the rotating block 430 drives the clamping jaw 420 to rotate, and the clamping jaw 420 drives the vehicle parts to rotate, so that the vehicle parts can be sprayed in all directions.

[0040] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived based on the content disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all these other variations or modifications.
