Description

Technical Field

[0001] The present invention relates to the technical field of wheel processing equipment, and particularly relates to a mobile painting hanger for wheel processing. Background Art

[0002] In the automotive manufacturing and repair industries, as a key component, the surface painting quality of wheels directly affects the aesthetics and durability of products. Traditional wheel painting processing mostly uses fixed hangers, which have obvious limitations: on the one hand, the fixed working position makes it difficult to flexibly adjust the posture and position of the wheels during the painting process, easily resulting in spraying blind spots and affecting the coating uniformity; on the other hand, loading and unloading the wheels requires manual operation, with low efficiency and high labor intensity, making it difficult to meet the demands of large-scale production. In addition, the existing hangers lack effective shock absorption and balance designs, and are prone to jitter and tilt during the lifting process, which not only affects the painting accuracy but also poses safety hazards and reduces the service life of the equipment. With the continuous improvement of the automotive industry's requirements for production efficiency and product quality, developing a mobile painting hanger that can achieve flexible movement and efficient clamping of wheels while having stable operating performance has become an urgent problem in the industry.

[0003] In terms of lifting and moving, traditional lifting devices have problems such as low precision and limited movement; in terms of wheel clamping and disassembly, manual operation has low efficiency and high labor intensity, and traditional mechanical clamping has poor adaptability. In terms of the operating stability of the equipment, the lifting of the lifting box is prone to jitter, and traditional lifting devices are prone to tilt, resulting in unstable transmission.

[0023] Embodiment 1 Please refer to Figures 1-6 , the present invention provides a technical solution: a mobile painting hanger for wheel processing, including a track 1. There are track wheels 2 on the track 1. There is a bracket 3 on the track wheels 2. The bottom of the bracket 3 is connected with a bracket seat 4. The cross-section of the track 1 is an I-shaped structure. The track wheels 2 are symmetrically distributed on both sides of the track 1. The number of track wheels 2 on each side is two. The track wheels 2 are rotatably connected to the bracket 3. The bottom of the bracket seat 4 is successively provided with a lifting component and a clamping component; The lifting component includes two rotating shaft support plates 6 connected to the bottom of the bracket seat 4. A rotating shaft 7 is rotatably arranged between the two rotating shaft support plates 6. There is a belt pulley 8 on the rotating shaft 7. A transmission belt 9 is wound around the belt pulley 8. The bottom of the bracket seat 4 is also connected with a lifting motor 5. The output end of the lifting motor 5 is connected to the rotating shaft 7. One end of the transmission belt 9 away from the belt pulley 8 passes through a pulley 12 and is connected to a suspension rod 13. The suspension rod 13 is connected to the bottom of the bracket seat 4. Upper support shafts 15 are rotatably arranged on both sides of the pulley 12. The pulley side plates 14 are connected to both sides of the upper support shafts 15. The bottoms of the pulley side plates 14 on both sides are connected with the clamping component; The clamping component includes a lifting box 10 connected to the pulley side plate 14. There is a clamping jaw 11 inside the lifting box 10. The clamping jaw 11 includes a clamping jaw side rod and a clamping jaw support plate. An upper sliding groove 101 is opened at the inner top of the lifting box 10. A lower sliding groove 102 is opened at the bottom of the lifting box 10. The upper sliding groove 101 is slidably connected with the clamping jaw side rod. The bottom of the clamping jaw side rod extends out of the lower sliding groove 102 and is connected with the clamping jaw support plate. A driving component for controlling the movement of the clamping jaw 11 is arranged inside the lifting box 10.

[0024] By driving the forward and reverse rotation of the rotating shaft 7 and the belt pulley 8 through the lifting motor 5, the winding and relaxation of the transmission belt 9 are realized, and then the overall length of the transmission belt 9 is adjusted to realize the lifting of the lifting box 10. The bottom of the lifting box 10 clamps the wheels through the clamping assembly, and the movement of the track wheels 2 on the track 1 realizes the movement of the wheels during the painting process.

[0025] Further, the driving assembly includes a hydraulic telescopic rod 103 connected to the inner top of the lifting box 10. The output end of the hydraulic telescopic rod 103 is connected to a driving shaft 104. The number of the upper sliding grooves 101 and the lower sliding grooves 102 is two each and they are symmetrically arranged left and right. The hydraulic telescopic rod 103 is located at the center of the lifting box 10, and the number of the clamping jaws 11 is two.

[0026] Still further, both sides of the driving shaft 104 are connected with support plates 106.

A plurality of connecting rods 107 are rotatably connected to both sides of the support plates 106, and the other ends of the plurality of connecting rods 107 are rotatably connected to the corresponding clamping jaw side rods.

[0027] By driving the up and down movement of the driving shaft 104 through the hydraulic telescopic rod 103, the driving shaft 104 further drives the support plates 106 to move up and down. The support plates 106 realize the left and right movement of the clamping jaw side rods through the rotation of the connecting rods 107 and the sliding of the sliding plates 105. The clamping jaw side rods drive the clamping jaw support plate to move left and right, thereby realizing the clamping and disassembling of the wheels.

[0028] Embodiment Two Please refer to Figure 3 、 Figure 4 , on the basis of Embodiment One, vertical third sliding grooves 18 are formed on both sides of the pulley side plates 14.

The number of pulleys 12 is two and they are placed side by side.

[0031] By arranging two pulleys 12, a movable pulley block is realized. A certain gap is maintained between the two pulleys 12, and both are connected to the lifting box 10 through the pulley side plates 14. The structural arrangement of the two pulleys 12 reduces the inclination of the lifting box 10 during the lifting process, so that the overall stability is maintained during the lifting of the transmission belt 9.

[0032] The working principle of the present invention: When the present invention is in use, the forward rotation of the rotating shaft 7 and the belt pulley 8 is driven by the lifting motor 5 to relax the transmission belt 9, thereby adjusting the overall length of the transmission belt 9 and realizing the lowering of the lifting box 10; the downward movement of the drive shaft 104 is driven by the hydraulic telescopic rod 103, and the drive shaft 104 then drives the support plate 106 to move downward. The support plate 106 realizes the inward movement of the jaw side rod through the rotation of the connecting rod 107 and the sliding of the sliding plate 105, and the jaw side rod drives the jaw support plate to clamp the wheel; then the lifting motor 5 rotates in reverse, the transmission belt 9 is tightened, and the lifting box 10 moves upward to lift the wheel, and the movement of the wheel during the painting process is realized through the movement of the track wheel 2 on the track 1.
