Description

Technical Field

[0001] This invention relates to the field of automotive body drying and conveying systems, specifically a lifting conveying system for drying automotive bodies on an automobile production line. Background Technology

[0002] The car body drying conveyor system is mainly used to cooperate with the automobile production line to transfer the car body into the paint booth for forced drying. By controlling the temperature, the coating on the surface of the car body is dried to improve the efficiency of automobile production.

[0003] The car body drying conveyor system is independent of the automobile production line conveyor system. Currently, the car body drying conveyor system still has certain shortcomings. Because the drying conditions required for the outer coating and the inner component coating of the car body are different, the existing drying conveyor system can only keep the clamped car body in a constant state when it is fed into the paint booth. Within the designated area of ​​the paint booth, the existing conveyor system cannot directly rotate the car body, so there will be a certain difference in the drying efficiency of the inner and outer coatings. At the same time, the constant state of the car body is not conducive to the inspection of its internal components by the staff.

[0004] In view of this, a lifting conveyor system for drying car bodies on an automobile production line was designed to solve the above problems. Summary of the Invention

This invention sets up a lifting and conveying mechanism and a rotating and adjusting mechanism in two drying spaces inside the paint booth, and sets different drying conditions for the two drying spaces. When the fixed car body is transferred from the lifting and conveying mechanism to the rotating and adjusting mechanism, the direction of the bottom of the car body is changed during the transfer. The parts of the car body facing the heat source or away from the heat source can receive selective radiation, thereby meeting the drying requirements of the coating on different parts of the car body after it is flipped.

[0047] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0048] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the invention.

[0049] The following describes, with reference to the accompanying drawings, some embodiments of a lifting conveyor system for drying car bodies in an automobile production line.

[0050] Example 1:

[0051] Combination Figures 1 to 9 As shown, the present invention provides a lifting conveyor system for drying car bodies in an automobile production line, including a car body 500, a lifting conveyor mechanism 100 and a rotating adjustment mechanism 200 disposed on the floor of a paint booth, wherein the rotating adjustment mechanism 200 is disposed outside the lifting conveyor mechanism 100, a rotating mechanism 300 disposed inside the lifting conveyor mechanism 100, and a car body ring assembly mechanism 400 disposed inside the rotating mechanism 300, wherein the car body ring assembly mechanism 400 is used to fix the car body 500. The lifting conveyor mechanism 100 and the rotating adjustment mechanism 200 are disposed on the floor of the paint booth. According to temperature control requirements, the lifting conveyor mechanism 100 and the rotating adjustment mechanism 200 can be disposed in the drying area separated within the paint booth. The rotating adjustment mechanism 200 is used to provide rotational adjustment for the rotating mechanism 300, and the rotating mechanism 300 is used to provide a circumferential flipping platform for the car body ring assembly mechanism 400.

[0052] The rotating mechanism 300 includes a reinforced slide 310, three sets of reinforced springs 360 and three limiting tooth blocks 350, a housing 320 disposed inside the reinforced slide 310, a motor 330 installed inside the housing 320 and a gear 340 disposed at the top of the transmission shaft of the motor 330.

[0053] Each set of reinforcing springs has two 360° springs;

[0054] The bottom of the reinforced slide 310 has three rectangular slots, and three sets of reinforcing springs 360 are respectively set in the three rectangular slots. The three limiting teeth 350 are movably installed in the three rectangular slots.

[0055] The vehicle body ring assembly mechanism 400 includes a limiting track plate 420 movably installed in the top groove of the reinforcing slide table 310, a first load-bearing ring 410 fixedly installed on the outside of the limiting track plate 420, two beam plates 430 fixed on the first load-bearing ring 410, and a second load-bearing ring 440 fixedly installed on the two beam plates 430 away from the two ends of the first load-bearing ring 410. The inner side of the limiting track plate 420 is provided with ring teeth, a third hydraulic component 490 fixedly installed in the bottom hole of the first load-bearing ring 410, a beam frame 480 fixedly installed on the top of the hydraulic rod inside the third hydraulic component 490, and four arc-shaped traction frames 470 movably installed on the four ends of the beam frame 480.

[0056] The inner walls of the first load-bearing ring 410 and the second load-bearing ring 440 are each provided with two symmetrically distributed end tubes 450 and a shaft hole insertion rod 460 movably installed in the end tubes 450.

[0057] The other end of the arc-shaped traction frame 470 is movably mounted on the end of the shaft hole insertion rod 460 at the bottom;

[0058] The bottom of the end tube 450 is provided with a transverse groove, and the end of the shaft hole insertion rod 460 is adapted to pass through the transverse groove.

[0059] The inner end of the shaft hole insertion rod 460 is provided with a frustum-shaped plug.

[0060] The third hydraulic component 490 is pre-operated. As the hydraulic rod inside the third hydraulic component 490 rises, the beam 480 installed on top of it will push the four arc-shaped traction frames 470 to extend outward. Finally, the four shaft hole inserts 460 installed on the top of the four arc-shaped traction frames 470 will be pressed and moved outward laterally.

[0061] After the vehicle body 500 is lifted by the existing clamp and delivered to the middle of the inner cavity of the first load-bearing ring 410 and the second load-bearing ring 440, the third hydraulic component 490 can be operated again until the hydraulic sub-rod traction beam 480 and the four arc-shaped traction frames 470 in the third hydraulic component 490 are pulled. Then the four shaft hole insertion rods 460 stretched can quickly be inserted and fixed to the four shaft holes of the vehicle body 500. At this time, the vehicle body 500 will be in a suspended state.

[0062] As the motor 330 runs, its internal transmission shaft, in conjunction with the gear 340, will drive the inner ring teeth of the first load-bearing ring 410. Finally, the entire vehicle body ring assembly mechanism 400 can drive the vehicle body 500 to rotate in a circle. At this time, the vehicle body 500, which is in a horizontal and suspended state, can be fully dried inside the paint booth.

[0063] Example 2:

[0064] Combination Figures 4 to 6 As shown, based on Embodiment 1, the lifting and conveying mechanism 100 includes a transition rail 120 installed outside the inner slot of the first ring cover 210, a horizontal rail 110 installed at the other end of the transition rail 120, a first end 190 installed outside the horizontal rail 110, a plug 130 installed at one end of the horizontal rail 110, a first hydraulic component 140 fixedly installed inside the plug 130, a first outer frame 150 and a second outer frame 170 set on the hydraulic sub-rod inside the first hydraulic component 140, a second push rod 180 penetrating into the interior of the transition rail 120, and a first push rod 160 movably installed in the first end 190 and penetrating into the interior of the horizontal rail 110. The outer end of the first outer frame 150 is movably installed on the first push rod 160, and the outer end of the second outer frame 170 is movably installed on the second push rod 180.

[0065] The first end 190 and the second end 2101 have the same structure, and the inner end of the first end 190 is provided with a concave hole adapted to the inner end plug of the first push rod 160.

[0066] The length of the second outer frame 170 is twice the length of the first outer frame 150;

[0067] The length of the inner rod of the second push rod 180 is twice the length of the inner rod of the first push rod 160.

[0068] Preferably, the horizontal rail 110 and the adapter rail 120 can be fixedly installed on the floor of the paint booth by bolts. The pad at one end of the adapter rail 120 is installed on the stud on the outside of the horizontal rail 110 by nuts. At this time, the horizontal rail 110 and the adapter rail 120 will form an L-shaped groove.

[0069] When the first hydraulic component 140 is running, its internal hydraulic rod will drive the first outer frame 150 and the second outer frame 170 to move. At this time, the first push rod 160 and the second push rod 180 can lift and deliver the rotating mechanism 300 into the circumferential adjustment mechanism 200. At this time, the rotating mechanism 300 can quickly change position between the horizontal rail 110 and the circumferential adjustment mechanism 200.

[0070] Example 3:

[0071] Combination Figures 6 to 9 As shown, based on Embodiment 1, the circumferential adjustment mechanism 200 includes a base 240, four support rods 2401 fixedly installed on the base 240, a compression spring 270 disposed outside the support rods 2401, a first ring cover 210 fixedly installed on the top of the base 240, a second end 2101 disposed outside the first ring cover 210, a second ring cover 220 disposed on the top of the first ring cover 210, an internal toothed ring pad 290 disposed inside the first ring cover 210 and the second ring cover 220, a top plate 250 installed outside the four support rods 2401, a second hydraulic component 260 fixedly installed inside the top plate 250, and a base 230 installed on the top of the second ring cover 220.

[0072] The bottom end of the hydraulic sub-rod inside the second hydraulic component 260 is fixedly installed inside the base 230;

[0073] The bottom end of the arc-shaped traction frame 470 is pressed against the end of the second ring cover 220, and the top end of the arc-shaped traction frame 470 is pressed against the bottom of the top plate 250.

[0074] The rotating adjustment mechanism 200 also includes two clamps 280 fixed to the top of the base 240 and a booster wheel 2801 movably installed in the two clamps 280, and one end of the shaft inside the booster wheel 2801 is provided with an I-shaped drive wheel.

[0075] The hub of the booster wheel 2801 is equipped with a ring gasket to increase frictional resistance, and the ring gasket has a toothed opening on its outer side.

[0076] The outer wall of the built-in toothed ring pad 290 is provided with evenly distributed protrusions, and the teeth on the outside of the ring pad are adapted to fit the protrusions on the outer wall of the built-in toothed ring pad 290.

[0077] Preferably, the pad at the other end of the adapter rail 120 is fixed to the stud on the outer slot of the first ring cover 210 by a nut. When the first push rod 160 and the second push rod 180 transfer the reinforcing slide 310 to the inner side of the first ring cover 210, the three limiting teeth 350 set in the rectangular slot at the bottom of the reinforcing slide 310 can be quickly engaged in the teeth on the inner side of the built-in toothed ring pad 290. As the external drive is driven by the belt drive of the booster wheel 2801, the built-in toothed ring pad 290 pressed by the booster wheel 2801 will rotate the engaged rotating mechanism 300 in a circular motion. Finally, the rotating mechanism 300 can be adjusted and controlled. At this time, the suspended body 500, which is fixed by the body ring mechanism 400, can be exposed to the maximum extent, so as to facilitate quick inspection and maintenance by the staff.

[0078] The working principle and usage process of this invention are as follows: The vehicle body 500 is first delivered towards the port of the second load-bearing ring 440 using an external clamp. Then, the third hydraulic component 490 is operated. As the hydraulic rod inside the third hydraulic component 490 extends upward, the beam frame 480 installed at the top of the hydraulic rod will simultaneously push the four arc-shaped traction frames 470. At this time, the four evenly distributed shaft hole insertion rods 460 will be compressed and retract into the inner cavity of the four end tubes 450. Then, the vehicle body 500 is continuously delivered to the middle of the inner cavity of the second load-bearing ring 440 and the first load-bearing ring 410 using an external clamp until the two shaft holes at the front and rear ends of the vehicle body 500 are symmetrical with the four shaft hole insertion rods 460.

[0079] Once the delivered vehicle body 500 is delivered to the middle of the inner cavity of the first load-bearing ring 410 and the second load-bearing ring 440 and positioned, the third hydraulic component 490 can be operated again until its internal hydraulic sub-rod retracts, and the four shaft hole insertion rods 460 pulled by the beam frame 480 and the four arc-shaped traction frames 470 will be inserted and fixed to the four shaft holes of the vehicle body 500.

[0080] After the vehicle body 500 is fixed in the middle of the inner cavity of the vehicle body ring assembly mechanism 400, the rotating mechanism 300 can be pulled by the external rope. The rotating mechanism 300 can then push the horizontally placed vehicle body ring assembly mechanism 400 along the inner groove of the horizontal rail 110 until the reinforcing slide 310 moves to the inner end of the horizontal rail 110. Then the first hydraulic component 140 is operated until its internal hydraulic rod extends outward. The first outer frame 150 and the second outer frame 170 installed on the hydraulic rod inside the first hydraulic component 140 will be pressed and push the first push rod 160 and the second push rod 180 to move. Finally, the first push rod 160 and the second push rod 180 can push the rotating mechanism 300 from the groove inside the adapter rail 120 into the inside of the first ring cover 210. At this time, the middle part of the vehicle body 500 can be located in the middle area between the first ring cover 210 and the second ring cover 220.

[0081] As the booster wheel 2801 is driven, it will push the built-in toothed ring pad 290 to rotate at a constant speed along the inner cavity of the first ring cover 210 and the second ring cover 220. At this time, the rotating mechanism 300, which is engaged inside the built-in toothed ring pad 290 and limited and constrained by the first ring cover 210 and the second ring cover 220, will be pushed circumferentially. At this time, the body 500, which is fixed by the body ring mounting mechanism 400, can be rotated and adjusted inside the first ring cover 210 and the second ring cover 220.

[0082] The vehicle body 500 is provided with a circumferential rotation platform by the vehicle body ring mounting mechanism 400. As the motor 330 runs and cooperates with the gear 340 to drive the outer ring teeth of the limit track plate 420 to rotate, the vehicle body 500 in the drying chamber can be rotated and dried. In order to inspect the internal components of the vehicle body 500 and check the coating drying effect during the drying process, the rotating mechanism 300 is lifted and delivered into the first ring cover 210 and the second ring cover 220. With the rotation of the rotating mechanism 300 as a whole by the built-in toothed ring pad 290, the rotating mechanism 300 will eventually be transferred to the top of the built-in toothed ring pad 290. At this time, the vehicle body 500 is exposed to the maximum extent. The suspended vehicle body 500 can continue to rotate within the first ring cover 210 and the second ring cover 220, which makes it convenient for staff to inspect and repair the internal components and coating of the vehicle body 500.

[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.
