[0027] Preferably, the cross track 110 and the transfer track 120 can be fixedly installed on the ground of the paint baking room by bolts. The foot pad at one end of the transfer track 120 is installed on the stud outside the cross track 110 through a nut. At this time, the cross track 110 and the transfer track 120 will form an L-shaped chute; When the first hydraulic component 140 operates, the internal hydraulic sub-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 rotary mechanism 300 into the ring rotation and positioning mechanism 200. At this time, the rotary mechanism 300 can quickly change positions between the cross track 110 and the ring rotation and positioning mechanism 200.

[0028] Embodiment 3: Combined Figures 6 to 9 As shown, on the basis of Embodiment 1, the ring rotation and positioning mechanism 200 includes a base 240, four support rods 2401 fixedly installed on the base 240, a compression spring 270 arranged outside the support rods 2401, a first ring cover 210 fixedly installed on the top of the base 240, a second end head 2101 arranged outside the first ring cover 210, a second ring cover 220 arranged on the top of the first ring cover 210, an internal toothed ring pad 290 arranged 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; The bottom end of the hydraulic sub-rod inside the second hydraulic component 260 is fixedly installed inside the base 230; The bottom end of the arc-shaped traction frame 470 bears on the end of the second ring cover 220, and the top end of the arc-shaped traction frame 470 bears on the bottom of the top plate 250; The ring rotation and position adjustment mechanism 200 further includes two clamps 280 fixed to the top of the base 240 and a boosting wheel 2801 movably installed in the two clamps 280, and one end of the inner shaft of the boosting wheel 2801 is provided with an I-shaped driving wheel.

[0029] A ring gasket for increasing the frictional resistance is installed outside the hub of the boosting wheel 2801, and a tooth opening is provided on the outside of the ring gasket; The outer wall of the built-in toothed ring gasket 290 is provided with evenly distributed protrusions, and the tooth opening outside the ring gasket fits and adheres to the protrusions on the outer wall of the built-in toothed ring gasket 290.

[0030] Preferably, the foot pad at the other end of the transfer rail 120 is fixed to the stud in the outer slot of the first ring cover 210 by a nut. When the first push rod 160 cooperates with the second push rod 180 to transfer the strengthening slide 310 to the inside of the first ring cover 210, the three limit tooth blocks 350 in the rectangular slot at the bottom of the strengthening slide 310 can quickly engage with the tooth openings inside the built-in toothed ring gasket 290. After the external drive device drives the boosting wheel 2801 through the belt, the built-in toothed ring gasket 290 pressed by the boosting wheel 2801 will circumferentially flip the engaged rotary circular mechanism 300. Finally, the whole rotary circular mechanism 300 can be adjusted in position. At this time, the vehicle body 500 fixed and suspended by the vehicle body ring mounting mechanism 400 can be maximally exposed, so as to facilitate quick inspection and maintenance by the staff.

[0031] The working principle and usage process of the present invention: First, use an external fixture to deliver the vehicle body 500 towards the port of the second load-bearing ring 440. Then, operate the third hydraulic component 490. As the hydraulic sub-rod in the third hydraulic component 490 extends upward, the beam frame 480 installed at the top of the hydraulic sub-rod will simultaneously push the four arc-shaped traction frames 470. At this time, the four uniformly distributed shaft hole inserting rods 460 will be pressed and contract towards the inner cavities of the four end tubes 450. Then, use the external fixture to continuously deliver the vehicle body 500 to the middle of the inner cavities of the second load-bearing ring 440 and the first load-bearing ring 410 until the two shaft holes at the head and tail ends of the vehicle body 500 are symmetrical with the four shaft hole inserting rods 460; When the delivered vehicle body 500 is delivered to the middle of the inner cavities 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 the internal hydraulic sub-rod contracts. The four shaft hole inserting rods 460 pulled by the beam frame 480 and the four arc-shaped traction frames 470 will insert and fix the four shaft holes of the vehicle body 500; After the vehicle body 500 is fixed in the middle of the inner cavity of the vehicle body ring mounting mechanism 400, the rotary circle mechanism 300 can be towed by an external rope. Then, the entire rotary circle mechanism 300 can push the vehicle body ring mounting mechanism 400 clamped and placed horizontally along the inner chute of the horizontal rail 110 until the strengthening slide table 310 moves to the inner end of the horizontal rail 110. Then, the first hydraulic component 140 is operated until the inner hydraulic rod thereof extends outwards. The first outer frame 150 and the second outer frame 170 installed on the inner hydraulic rod of the first hydraulic component 140 will be pressed to 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 rotary circle mechanism 300 from the chute inside the transfer 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; After the boost wheel 2801 is driven, the boost wheel 2801 will push the built-in toothed ring pad 290 to rotate uniformly along the inner cavities of the first ring cover 210 and the second ring cover 220. At this time, the rotary circle mechanism 300 clamped 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 receive a circumferential push. At this time, the vehicle body 500 with the vehicle body ring mounting mechanism 400 fixed can perform rotary alignment adjustment on the inner sides of the first ring cover 210 and the second ring cover 220; The vehicle body ring mounting mechanism 400 provides a circumferential rotation platform for the vehicle body 500. After the motor 330 operates 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. When checking the internal components of the vehicle body 500 and the coating drying effect during drying, the rotary circle mechanism 300 is jacked up and delivered into the first ring cover 210 and the second ring cover 220. Along with the rotation of the built-in toothed ring pad 290 as a whole for the rotary circle mechanism 300, finally, the rotary circle mechanism 300 will move to the top of the built-in toothed ring pad 290. At this time, the vehicle body 500 is maximally exposed, and the suspended vehicle body 500 can still rotate inside the first ring cover 210 and the second ring cover 220, so that it is convenient for the staff to repair and check the internal components and the coating of the vehicle body 500.
