[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figures 1-5 A transition roller bed for a vehicle frame painting conveyor line includes a bed frame 1 and a drive assembly 9. Two fixing rods 2 are bolted to the top of the bed frame 1. Multiple mounting holes 3 are provided on one side of each fixing rod 2. Multiple sets of transition roller assemblies 4 are located at the top between the two fixing rods 2. Each transition roller assembly 4 includes a support block 401. A bearing seat 402 is bolted to the top of the support block 401. A conveyor roller 403 is rotatably mounted between the two bearing seats 402 via an interlocking bearing. A connecting plate 404 is welded to one side of the support block 401. A connecting hole 405 is provided on one side of the connecting plate 404. A connecting bolt 5 is inserted into the connecting hole 405. One end of the connecting bolt 5 passes through the mounting hole 3 and is threaded with a connecting nut. The connecting nut is unscrewed, and the connecting bolt 5 is pulled out from the mounting hole 3 and the connecting hole 405. Then, the transition roller assembly 4 is pushed, causing the movable wheel 409 to roll on the support rail 6, thereby moving the transition roller assembly 4 to adjust the distance between the multiple conveyor rollers 403 as needed.

[0018] One end of the conveyor roller 403 is keyed to a worm gear 406. A worm 407 is rotatably mounted on one side of a connecting plate 404 via an interlocking bearing. The worm 407 meshes with the worm gear 406. A square hole 408 is provided between the two ends of the worm 407. The drive assembly 9 is inserted into the square hole 408. Driven by the drive motor 905, and driven by the meshing of the worm 407 and the worm gear 406, the conveyor roller 403 is rotated, thereby providing power for the frame conveying.

[0019] The bottom of the support block 401 is rotatably connected to two movable wheels 409. The top of the fixed rod 2 is fixed to the support rail 6 by bolts. The movable wheels 409 roll in the support rail 6, which makes the transition roller assembly 4 move more easily.

[0020] A vertical plate 410 is welded to the top of the support block 401. A protective shell 411 is connected to the top of the vertical plate 410 via a hinge. The protective shell 411 covers the outside of the connecting bolt 5. Magnetic blocks 412 are glued to the inner wall of one side of the protective shell 411 and one side of the connecting plate 404. The two magnetic blocks 412 attract each other, thereby fixing the protective shell 411 to the outside of the connecting bolt 5, thus preventing accidental contact with the connecting bolt 5.

[0021] Support rods 7 are welded between the inner walls on both sides of the bed frame 1. The top of the support rods 7 is fixedly connected to the bottom of the fixed rods 2. Two connecting ribs 8 are welded to the bottom of the support rods 7. One side of the connecting ribs 8 is fixedly connected to the inner wall of one side of the bed frame 1. The support rods 7 and the connecting ribs 8 strengthen the connection between the fixed rods 2 and the bed frame 1.

[0022] The drive assembly 9 includes a side frame 901, and a top frame 902 is bolted to the top of the side frame 901. Rotating rods 904 are rotatably mounted on both sides of the top frame 902 via embedded bearings. A square rod 903 is fixedly connected between the two rotating rods 904 via a pin. The square rod 903 is inserted into a square hole 408, which facilitates the rotating rod 904 to drive the square rod 903 to rotate. At the same time, it facilitates the square hole 408 of the worm gear 407 to move along the square rod 903 so as to adjust the connection position between the worm gear 407 and the square rod 903, so as to adapt to the adjustment of the distance between multiple conveying rollers 403. A drive motor 905 is bolted to the top of the side frame 901. The output end of the drive motor 905 is fixedly connected to one end of one of the rotating rods 904. Driven by the drive motor 905, the rotating rod 904 and the square rod 903 rotate, thereby driving the worm gear 407 to rotate. Then, under the action of the worm gear 407 meshing with the worm wheel 406, the conveying roller 403 rotates, thereby conveying the frame.

[0023] The working principle of this embodiment is as follows: When it is necessary to adjust the distance between multiple conveying rollers 403, firstly, open the protective shell 411 to separate the two magnetic blocks 412, then unscrew the connecting nut, and then pull the connecting bolt 5 out of the mounting hole 3 and the connecting hole 405. Then, push the transition roller assembly 4 to make the movable wheel 409 roll on the support rail 6, thereby driving the transition roller assembly 4 to move so as to adjust the distance between multiple conveying rollers 403 as needed. At the same time, drive the square hole 408 of the worm 407 to move along the square rod 903 so as to adjust the connection position between the worm 407 and the square rod 903. Then, pass the connecting bolt 5 through the connecting hole 405 and the mounting hole 3, and tighten the connecting nut to fix the position of the transition roller assembly 4. Then, the drive motor 905 is started. Driven by the drive motor 905, the rotating rod 904 and the square rod 903 rotate, thereby driving the worm 407 to rotate. Then, under the action of the worm 407 meshing with the worm wheel 406, the conveying roller 403 rotates, thereby conveying the frame.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
