In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0028] A 90° fixed-angle rotating hanger 4 mechanism, characterized in that it includes a support 2 for supporting the entire mechanism, a rotating hanger 4 that can rotate at a fixed 90° angle, a conveyor trolley 3 that provides power for the rotating hanger 4, and an auxiliary component that cooperates with the rotation of the rotating hanger 4. The conveyor trolley 3 is fixedly connected to the rotating hanger 4. The conveyor trolley 3 is connected to the conveyor track 1 by rolling with rollers. The conveyor trolley 3 rolls forward in the conveyor track 1, and the conveyor track 1 is fixedly connected to the support 2.

[0029] Furthermore, the rotating hanger 4 includes a hanging bow 401, a rotating positioning disk 406, a positioning block 407, and a hanging plate 408. The rotating positioning disk 406 is arranged below the hanging bow 401 and is connected by a bushing 403. A rotating shaft 410 is provided in the bushing 403. The lower end of the rotating shaft 410 is fixedly connected to the rotating positioning disk 406, and the upper end passes through the bushing 403 and is locked by a locking nut 402. One end of the hanging bow 401 is fixedly connected to the outer wall of the bushing 403. One end of the positioning block 407 is rotatably connected to the outer wall of the bushing 403 by a shaft pin. A positioning pin and an auxiliary support rod 413 are provided on the positioning block 407. The positioning pin is perpendicularly fixedly connected to the lower end of the positioning block 407 with respect to the rotating positioning disk 406. The auxiliary support rod 413 extends outward parallel to the rotating positioning disk 406 and is connected to the side end of the positioning block 407. The rotating positioning disk 406 includes four grasping parts and four positioning grooves 414. The lower end of each grasping part is fixedly connected to a guiding shaft 405. The distribution of the positioning grooves 414 is the same as that of the grasping parts. The positioning pin is snapped into the positioning groove 414 to fix the rotating positioning disk 406.

[0030] Further, the auxiliary assembly includes a guide rod 5, a lifting guide rail 6, a push plate 7, and a weight 8. Both ends of the guide rod 5 are fixedly connected to the two lower arms of the support 2 through fixing rods. The guide rod 5 prevents the rotary hanger 4 from swinging left and right. The lifting guide rail 6 is fixedly connected to the support 2. One end of the lifting guide rail 6 is bent downward and is arranged below the auxiliary rod 413. The other end is a parallel section. When the rotary hanger 4 moves forward along the guide rail, the auxiliary rod 413 of the positioning block 407 slides and lifts on the lifting guide rail 6, causing the positioning pin to disengage from the positioning slot 414. One end of the push plate 7 is fixedly connected to the support 2, and the other end is used to toggle the guide shaft 405 to rotate the rotary positioning disk 406; the weight 8 is connected to the support 2 through a shaft and swings freely to cause the rotary positioning disk 406 to complete a 90° rotation.

[0031] Further, the positioning block 407 and the hanging bow 401 are arranged oppositely.

[0032] Further, the positioning pin adopts a tapered end structure, and the upper half of the positioning slot 414 is chamfered to make it easy for the positioning pin to fall into the positioning slot 414.

[0033] Further, the end face of the push plate 7 adopts an arc-shaped structure to ensure smooth rotation.

[0034] Further, a mounting plate is fixed on the support 2. The lifting guide rail 6 is fixedly connected to the mounting plate through an L-shaped plate. The push plate 7 is L-shaped and is fixedly connected to the mounting plate. The weight 8 is connected to the mounting plate through a swing shaft.

[0035] Further, at least one hanging plate 408 is provided at the lower end of the rotary positioning disk 406. A hanging shaft 409 is fixedly connected to the hanging plate 408, and the hanging shaft 409 is used to connect the welding machine.

[0036] Further, a pressure bearing 411 is provided in the bushing 403. The pressure bearing 411 is connected to the upper end of the rotary shaft 410 and is fixed by a bearing cover plate 412 to reduce the rotary resistance.

[0037] Further, an I-shaped fixing platform is provided in the middle of the bushing 403. The connecting end of the positioning block 407 and the bushing 403 is inserted into the fixing platform and is connected by a shaft pin, enabling the positioning block 407 to rotate up and down with the shaft pin as the axis.

[0038] Among them, the rotary hanger 4 is composed as Figure 2 shown. The rotary shaft 410 is connected to the rotary positioning disk 406 and the hanging plate 408. The rotary shaft 410 can rotate in the bushing 403. A pressure bearing 411 is provided at the upper end of the shaft, which can effectively reduce the rotary resistance. The positioning block 407 can rotate up and down in the bushing 403 through the pin shaft 404. The rotary hanger 4 can rotate by pushing the guide shaft 405 on the positioning disk.

[0039] The rotating hanger 4 is fixed on the conveyor trolley 3 through the pin shaft 404 and moves forward with the trolley. The workpiece to be sprayed is hung on the hanging shaft 409 through the secondary hanger. The positioning pin shaft 404 on the positioning block 407 falls into the positioning groove 414 on the rotating positioning disc 406 to position the direction of the hanger. When the hanger runs to the position where it needs to rotate 90°, a guiding mechanism is set in front of it to accurately position the hanger after it rotates 90°. After the hanger enters the rotating area, the guiding rod 5 set on the support 2 guides the hanging bow 401 of the hanger to prevent the hanger from swinging left and right. As the trolley moves forward, the positioning block 407 on the rotating hanger 4 slides upward along the lifting guide rail 6, so that the positioning pin disengages from the positioning groove 414 and releases the positioning of the hanger; one end of the lifting guide rail 6 is bent downward, so that the auxiliary support rod 413 of the positioning block 407 just rests on the lifting guide rail 6. When the conveyor trolley 3 moves forward, the auxiliary support rod 413 is continuously lifted with the height of the lifting guide rail 6. When the auxiliary support rod 413 enters the parallel section of the lifting guide rail 6, the positioning pin of the positioning block 407 is just pulled out from the positioning groove 414. Subsequently, the push plate 7 pushes the guiding shaft 405 on the rotating hanger 4 to continuously rotate the hanger. As the hanger continues to move forward, the rotating positioning disc 406 continues to rotate, the positioning block 407 disengages from the lifting guide rail 6, and the positioning pin falls on the upper surface of the rotating positioning disc 406. As Figure 4 , under the push of the push plate 7, the rotating positioning disc 406 rotates up to the position of 70°. Then, under the push of the weight 8, the rotating positioning disc 406 continues to rotate until the positioning pin falls into the positioning groove 414, and the hanger completes a 90° rotation and positioning.

[0040] The positioning pin adopts a taper-end structure, and the upper half of the positioning groove 414 is chamfered at an angle, so that the positioning pin can easily fall into the positioning groove 414. As Figure 7 shown in the structure.

[0041] The weight 8 can rotate freely on the shaft. Its function is to push the hanger to rotate in place so that the positioning pin can reliably fall into the positioning groove 414. At the same time, after the weight 8 is stressed and rotates at a certain angle, the hanger can pass through smoothly.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
