Description

Technical Field

[0001] This utility model relates to the technical field of wheel hub processing equipment, and in particular to a suspended feeding mechanism for wheel hub spraying. Background Technology

[0002] As a cylindrical metal component that supports the tire's inner contour, the quality of the surface coating of the wheel hub is crucial to its appearance and service life. In wheel hub coating production, the suspended feeding mechanism is the key equipment to achieve continuous and efficient wheel hub coating, and it mainly works in conjunction with the automatic circulating conveyor chain and the spray booth to complete the operation.

[0003] Currently, the suspended feeding components of existing wheel hub painting lines are mostly arranged at intervals along the automatic circulating conveyor chain. The core structure is usually a T-shaped frame with two sets of horizontal hooks. The wheel hubs are suspended from the frame through the hooks for conveying. However, this traditional suspended feeding mechanism has obvious limitations in practical applications: on the one hand, it has a single function, only able to achieve suspended conveying through hooks, and cannot adapt to the diverse needs of painting processes for feeding posture, thus limiting its application scenarios; on the other hand, due to structural design limitations, the number of wheel hubs that can be conveyed in a single suspension is small, making it difficult to match the production capacity of high-efficiency painting equipment, thus restricting the overall production efficiency of the painting line and failing to meet the needs of large-scale production. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose a suspended feeding mechanism for wheel hub spraying. This device has a reasonable structure and can switch between ground and suspended modes by adjusting the linkage between the column and the connecting rod, breaking through the limitations of traditional mechanisms. It can simultaneously transport no less than four sets of wheel hubs, which greatly improves efficiency compared with traditional mechanisms. The structure is stable and precise with the help of elastic clips and limiting components. The threaded connection of the axle seat is easy to disassemble and adapt to wheel hubs of different specifications. It can also be compatible with automation upgrades, improve the uniformity of spraying, and has strong overall practicality.

[0006] To achieve the above objectives, this utility model proposes a suspended feeding mechanism for wheel hub painting, including a hanging rail and a pulley seat slidably connected to the surface of the hanging rail. The pulley seat is driven by a drive chain on the hanging rail. It also includes a suspension mechanism disposed at the bottom of the pulley seat, the suspension mechanism comprising:

[0007] U-shaped bracket: The inner wall is symmetrically threaded with limiting shafts, and the surfaces of the two sets of limiting shafts are horizontally slidably connected with side blocks. The surfaces of the two sets of limiting shafts that are close to each other are fixedly connected with L-shaped overlapping blocks, and are arranged in opposite directions.

[0008] Adjusting column: It is vertically slidably connected to the center of the inner wall of the U-shaped bracket, and a middle block is fixedly connected to its top. The bottom of the middle block overlaps the surface of two sets of L-shaped overlapping blocks, and positioning holes are symmetrically opened on its lower end surface.

[0009] Connecting rods: symmetrically and in opposite directions are rotatably connected to the upper side facade of the middle block, and the other ends of the two sets of connecting rods are rotatably connected to the lower side facades of the two sets of side blocks respectively;

[0010] V-shaped frame: Fixedly connected to the bottom of the U-shaped bracket, with an adjusting rod fixedly connected to the center of its inner wall. The bottom of the adjusting rod is provided with a threaded part and is screwed to the bottom of the pulley seat. The upper end of the adjusting rod passes through the interior of the adjusting column rod and is symmetrically provided with elastic clips that are engaged and fixed with the positioning holes.

[0011] Top and side mounting brackets: respectively screwed to the top and side of the edge block and middle block.

[0012] In addition, the suspension feeding mechanism for wheel hub painting proposed above may also have the following additional technical features:

[0013] Specifically, a limiting block and a limiting groove are respectively provided at the bottom wall of the rod groove of the side block and at the bottom position of the limiting shaft rod, and the limiting block is slidably connected to the inner wall of the limiting groove.

[0014] Specifically, the height of the middle block is lower than the height of the edge blocks, and the top of the middle block and the tops of the two sets of edge blocks are on the same horizontal plane.

[0015] Specifically, positioning screw cylinders are provided at the corresponding positions on the upper side facade of the middle block and the lower side facade of the side block, and the connecting rod is provided at the corresponding positions on the side facade of the side block. The connecting rod is sleeved on the outside of the positioning screw cylinder and is rotatably connected to the outer surface of the positioning screw cylinder.

[0016] Specifically, the number and structure of the top bearing and the side bearing are the same. There are four sets of top bearings. The top bearing includes a tapered fixing seat, a limiting plate and a connecting screw arranged in sequence along the vertical direction. The connecting screw of the top bearing is threaded to the inner wall of the threaded hole opened on the top of the side block, and the connecting screw of the side bearing is threaded to the inner wall of the positioning screw cylinder.

[0017] Specifically, the conical fixing seat surface is symmetrically provided with a limiting mechanism. The limiting mechanism includes a groove, a wheel bracket, a roller, and a damping ring. The groove is formed on the surface of the conical fixing seat. One end of the wheel bracket is rotatably connected to the inner wall of the groove, and a torsion spring is provided between the wheel bracket and the inner wall of the groove. The other end of the wheel bracket extends through the outside of the groove and is rotatably connected to the roller. The damping ring is sleeved on the surface of the conical fixing seat and is located on one side of the bottom of the groove.

[0018] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] 1. Wide range of applications and high flexibility: It breaks through the limitation of traditional mechanisms that can only be used in suspended mode. Through structural adjustment, it can switch between ground and suspended modes, adapt to different spraying processes (such as ground operation of fixed spraying equipment and suspended operation of spraying robots), and improve the versatility of the equipment.

[0021] 2. Increased conveying capacity and improved efficiency: Traditional mechanisms can convey a maximum of 2 sets of wheel hubs at a time, while this mechanism, through the multi-station design of side blocks and middle blocks, can convey no less than 4 sets of wheel hubs simultaneously in ground or suspended scenarios, greatly increasing the conveying capacity per time, matching the production capacity of high-efficiency spraying equipment, and improving the overall production line efficiency.

[0022] 3. Stable structure and precise positioning: During the adjustment process, the engagement of the elastic clips with the positioning holes, the support of the L-shaped overlapping blocks for the middle blocks, and the cooperation of the limiting blocks with the limiting slides ensure that the position is fixed after structural adjustment and that the hub height and spacing are consistent; the limiting mechanism (rollers, damping rings, torsion springs) effectively prevents the hub from shifting during transportation through mechanical pressing and friction, ensuring the spraying accuracy.

[0023] 4. Easy to install and disassemble, highly adaptable: The top bearing and the side bearing are connected by threads for quick installation and disassembly, and different sizes of bearings can be replaced according to the wheel hub specifications; the sliding adjustment of the adjusting column does not require tools, making it easy to quickly switch scenes and reduce the difficulty of operation;

[0024] 5. Compatible with automation upgrades: By adding an electric drive mechanism inside the bearing seat, or by using gears in conjunction with an external rack, the hub can be driven to rotate during the conveying process, thereby improving the uniformity of spraying and adapting to the needs of automated spraying production lines.

[0039] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0040] The suspended feeding mechanism for wheel hub painting according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0041] like Figures 1-5As shown, the suspended feeding mechanism for wheel hub painting according to an embodiment of the present invention includes a hanging rail 100 and a pulley seat 200 slidably connected to the surface of the hanging rail 100. The pulley seat 200 is driven by a drive chain 300 on the hanging rail 100. It also includes a suspension mechanism disposed at the bottom of the pulley seat 200, the suspension mechanism comprising:

[0042] U-shaped bracket 1: The inner wall is symmetrically threaded with limiting shafts 11. Both sets of limiting shafts 11 are horizontally slidably connected with side blocks 12. The surfaces of the two sets of limiting shafts 11 that are close to each other are fixedly connected with L-shaped overlapping blocks 13, and are set in opposite directions.

[0043] Adjusting column 2: It is vertically slidably connected to the center of the inner wall of the U-shaped bracket 1, and a middle block 21 is fixedly connected to its top. The bottom of the middle block 21 overlaps the surface of two sets of L-shaped overlapping blocks 13, and positioning holes 22 are symmetrically opened on its lower end surface.

[0044] Connecting rod 3: symmetrically and in opposite directions, it is connected to the upper side facade of the middle block 21. The other ends of the two sets of connecting rods 3 are respectively rotatably connected to the lower side facades of the two sets of side blocks 12.

[0045] V-shaped frame 4: It is fixedly connected to the bottom of the U-shaped bracket 1. An adjusting rod 41 is fixedly connected to the center of its inner wall. The bottom of the adjusting rod 41 is provided with a threaded part 411 and is screwed to the bottom of the pulley seat 200. The upper end of the adjusting rod 41 passes through the interior of the adjusting column rod 2 and is symmetrically provided with elastic clips 42 that are locked to the positioning hole 22.

[0046] Top bearing 5 and side bearing 6: are screwed and fixed to the top and side of edge block 12 and middle block 21, respectively.

[0047] It should be noted that in the existing suspended feeding assembly, the T-shaped frame 400 is fixed to the bottom of the pulley seat 200, and the two sets of horizontal hooks 500 are arranged in sequence on the T-shaped frame 400 in the vertical direction. The existing single-set suspended feeding assembly can only transport two sets of wheel hubs at a time, while the existing ground conveying assembly can only transport one set of wheel hubs.

[0048] It should be noted that, in this embodiment, the top axle seat 5 is used for ground transportation to support and limit the wheel hub, while the side axle seat 6 is used for suspended transportation to support and limit the wheel hub.

[0049] It should be noted that there are two sets of positioning holes 22. The upper set is used for precise positioning of the elastic clip 42 when it is used for hanging, and the lower set is used for precise positioning of the elastic clip 42 when it is used on the ground.

[0050] It should also be noted that the adjusting rod 2 described in this embodiment is provided with a limiting ring platform 20, which is in contact with the bottom of the U-shaped bracket 1.

[0051] Specifically, this device has a reasonable structure. By adjusting the linkage between the column rod 2 and the connecting rod 3, it can switch between ground and suspended scenarios, breaking through the limitations of traditional mechanisms. It can simultaneously transport no less than four sets of wheel hubs, which greatly improves efficiency compared to traditional mechanisms. With the help of elastic clips 42 and limit components, the structure is stable and precise. The threaded connection of the axle seat is easy to disassemble and adapt to wheel hubs of different specifications. It is also compatible with automation upgrades, improves the uniformity of spraying, and has strong overall practicality.

[0052] This device can achieve stable wheel hub transportation in both ground and suspended scenarios. The specific working process is as follows:

[0053] 1. Ground-based usage scenarios

[0054] Installation and fixing: Connect the threaded part 411 of the bottom adjusting rod 41 of the V-shaped frame 4 to the threaded cylinder of the ground conveying mechanism to complete the ground positioning of the entire device.

[0055] Structural adjustment: Pull down the adjusting column rod 2 to make it move vertically downward along the inner wall of the U-shaped bracket 1, which simultaneously drives the middle block 21 at the top to descend. The middle block 21 pulls the two sets of side blocks 12 through the connecting rods 3 at both ends, so that the side blocks 12 move horizontally outward along the limiting shaft rod 11 (the limiting block at the bottom of the limiting shaft rod 11 cooperates with the limiting slide groove in the rod groove of the side block 12 to ensure that the side block 12 slides horizontally without deviating).

[0056] Positioning and locking: When the elastic clip 42 at the upper end of the adjusting rod 41 engages with the lower positioning hole 22 at the lower end of the adjusting rod 2, the bottom of the middle block 21 just overlaps the L-shaped overlapping block 13. At this time, the top of the middle block 21 and the top of the two sets of side blocks 12 are on the same horizontal plane, ensuring that the wheel hub is placed at the same height.

[0057] Hub fixing: The top axle seat 5 is screwed to the threaded hole 122 on the top of the side block 12 and the middle block 21 through the connecting screw 53. The tapered fixing seat 51 of the top axle seat 5 is inserted into the center hole of the hub. The limiting mechanism 54 on its surface (the wheel bracket 542 in the groove 541 drives the roller 543 to press against the inner wall of the hub under the action of the torsion spring, and the damping ring 544 increases friction) realizes the stable positioning of the hub and avoids displacement during transportation.

[0058] 2. Suspension Usage Scenarios

[0059] Installation and fixing: Invert the device so that the threaded part 411 of the adjusting rod 41 faces upward and is screwed to the bottom of the pulley seat 200 on the hanging rail 100. The pulley seat 200 is driven by the drive chain 300 on the hanging rail 100 to drive the entire mechanism to slide along the hanging rail 100.

[0060] Structural adjustment: Pull up the adjusting column rod 2 to make it move vertically upward along the inner wall of the U-shaped bracket 1, which simultaneously drives the middle block 21 to rise. The middle block 21 pushes the two sets of side blocks 12 to move horizontally inward along the limiting shaft rod 11 through the connecting rod 3, thereby reducing the distance between the side blocks 12.

[0061] Positioning and locking: When the elastic clip 42 engages with the upper positioning hole 22 at the lower end of the adjusting column rod 2, the limiting ring platform 20 on the adjusting column rod 2 abuts against the bottom of the U-shaped bracket 1. At this time, the overall structure is trapezoidal (after the side block 12 moves inward, it forms a suitable suspension space with the middle block 21), which adapts to the space requirements of suspension conveying.

[0062] Hub fixing: The hub is screwed to the side positioning screw cylinder 121 of the side block 12 and the middle block 21 by the side vertical shaft seat 6 (which has the same structure as the top shaft seat 5). The conical fixing seat 51 and the limiting mechanism 54 are used to suspend and limit the hub to ensure stability during transportation.

[0063] Core coordination mechanism: The vertical sliding of the adjusting column rod 2 is converted into the horizontal movement of the side block 12 through the connecting rod 3. With the locking of the elastic clip 42 and the positioning hole 22, the structural form can be switched between the two scenarios. The limiting shaft rod 11, L-shaped overlapping block 13, limiting ring platform 20 and other components ensure the structural stability after adjustment and ensure the accurate conveying posture of the wheel hub.

[0064] It is worth noting that if the ground spraying device does not have a rotary spraying function, an electric drive mechanism (not shown in the figure) can be separately installed inside the top bearing 5 to drive the top bearing 5 and the hub to rotate. This is existing technology and will not be described in detail here. Alternatively, a gear can be installed on the top bearing 5 and connected to the rack to drive the top bearing 5 and the hub to rotate. This is also existing technology and will not be described in detail here.

[0065] When using the suspension, determine whether it is necessary to remove the top axle 5 based on the available space and usage requirements. If the structure is not affected during suspension use, it is acceptable not to remove it.

[0066] Because the spraying equipment is generally a spraying robot rather than a ground-fixed spraying device under suspended conveying, the four sets of side vertical bearings 6 can still ensure stable conveying and stable spraying even when the square shape is not satisfied.

[0067] In one embodiment of this utility model, such as Figure 1 As shown, a limit block and a limit groove are respectively provided at the bottom wall of the rod groove of the side block 12 and the bottom position of the limit shaft 11. The limit block is slidably connected to the inner wall of the limit groove.

[0068] It should be noted that the limiting block and limiting groove described in this embodiment are not shown in the diagram.

[0069] Specifically, the combination of the limiting block and the limiting slide can precisely limit the angle of the side block 12, ensuring that it always slides stably in the horizontal direction; at the same time, the design of the limiting slide at the bottom can effectively prevent paint from seeping into the slide during the spraying process, reduce the sliding jamming problem caused by material accumulation, ensure the long-term stable operation of the mechanism, and improve the reliability of use.

[0070] In one embodiment of this utility model, such as Figure 1 As shown, the height of the middle block 21 is lower than the height of the edge block 12, and the top of the middle block 21 and the top of the two sets of edge blocks 12 are on the same horizontal plane.

[0071] Specifically, the design that the height of the middle block 21 is lower than that of the edge block 12 is to provide more reasonable force angle adjustment space for the connecting rod 3 when the middle block 21 and the edge block 12 are linked by the connecting rod 3. When the middle block 21 moves up and down, the rotation angle of the connecting rod 3 can be more smoothly converted into the horizontal displacement of the edge block 12, reducing wear caused by structural jamming or excessive force, and improving the stability of the adjustment process.

[0072] The top of the middle block 21 is kept at the same level as the tops of the two sets of side blocks 12. This is to ensure that all wheel hubs are installed at the same height and level in ground use scenarios. This design ensures that the spraying distance and angle of the spraying equipment are consistent for multiple sets of wheel hubs, avoiding problems such as uneven spraying thickness caused by height differences, thereby ensuring the stability of spraying quality and improving the product qualification rate.

[0073] In one embodiment of this utility model, such as Figure 2 As shown, positioning screw cylinders 121 are provided at the corresponding positions of the connecting rod 3 on the upper side surface of the middle block 21 and the corresponding positions of the connecting rod 3 on the lower side surface of the side block 12. The connecting rod 3 is sleeved on the outside of the positioning screw cylinder 121 and is rotatably connected to the outer surface of the positioning screw cylinder 121.

[0074] It should be noted that the positioning screw cylinder 121 described in this embodiment is provided with a limiting groove on its surface, and the connecting rod 3 is located in the limiting groove.

[0075] Specifically, the positioning screw cylinder 121 provides a stable rotation fulcrum for the connecting rod 3. The limiting groove on its surface and the nested cooperation with the connecting rod 3 can precisely constrain the rotation angle of the connecting rod 3, preventing axial offset or shaking during linkage. This ensures stable and reliable motion transmission between the middle block 21 and the side block 12. At the same time, this structural design not only ensures the flexibility of the connecting rod 3's rotation, but also enhances the overall structural synergy through mechanical limiting, providing key support for smooth switching between the two usage scenarios and improving the stability and durability of the mechanism's operation.

[0076] In one embodiment of this utility model, such as Figure 1As shown, the top bearing 5 and the side bearing 6 have the same number and structure. There are four sets of top bearing 5. The top bearing 5 includes a tapered fixing seat 51, a limiting plate 52 and a connecting screw 53 arranged in sequence along the vertical direction. The connecting screw 53 of the top bearing 5 is threaded to the inner wall of the threaded hole 122 opened on the top of the side block 12. The connecting screw 53 of the side bearing 6 is threaded to the inner wall of the positioning screw cylinder 121.

[0077] Specifically, the top bearing 5 and the side bearing 6 adopt the same structural design, which simplifies the manufacturing process, reduces the cost of parts management, and ensures the consistency of the two bearings in function, making it easy to switch between them flexibly according to the scenario. The top bearing 5 is set into four groups, which are connected to the threaded hole 122 on the top of the side block 12 by the connecting screw 53, which is suitable for the horizontal placement requirements in the ground scenario. The side bearing 6 is connected to the inner wall of the positioning screw 121 by the connecting screw 53, which is suitable for the side suspension requirements in the suspension scenario. The tapered fixing seat 51 can be accurately embedded into the center hole of the wheel hub, and the limiting plate 52 provides support and limitation for the bottom or side of the wheel hub. With the detachability of the threaded connection, it can not only firmly fix wheel hubs of different specifications, but also facilitate quick disassembly and replacement, improving the adaptability of the mechanism to diverse production needs.

[0078] In one embodiment of this utility model, such as Figure 4 As shown, a limiting mechanism 54 is symmetrically arranged on the surface of the conical fixed base 51. The limiting mechanism 54 includes a groove 541, a wheel bracket 542, a roller 543, and a damping ring 544. The groove 541 is formed on the surface of the conical fixed base 51. One end of the wheel bracket 542 is rotatably connected to the inner wall of the groove 541, and a torsion spring is provided between the wheel bracket 542 and the inner wall of the groove 541. The other end of the wheel bracket 542 extends through the outside of the groove 541 and is rotatably connected to the roller 543. The damping ring 544 is sleeved on the surface of the conical fixed base 51 and is located on one side of the bottom of the groove 541.

[0079] Specifically, the limiting mechanism 54 on the surface of the conical fixing seat 51 is the core structure for achieving stable fixing of the wheel hub. Its components work together to form multiple limiting guarantees: the groove 541 provides installation space for the wheel bracket 542, ensuring that the limiting mechanism 54 does not protrude from the surface of the conical fixing seat 51 after being squeezed, thus avoiding interference with the inner wall of the center hole of the wheel hub; the wheel bracket 542 always has an outward opening tendency under the action of the torsion spring, driving the roller 543 at its end to fit tightly against the inner wall of the center hole of the wheel hub. Through rolling contact, it can adapt to wheel hubs with different hole diameters and reduce frictional resistance during disassembly and assembly; the damping ring 544 further enhances the friction between the conical fixing seat 51 and the inner wall of the wheel hub. Combined with the elastic pressing of the roller 543, it forms a dual fixing effect of "elastic support + friction damping", effectively preventing the wheel hub from shifting due to vibration and shaking during transportation or spraying, ensuring positioning accuracy and stability, while not affecting the rapid pick-up and drop operation of automated equipment.

[0080] In summary, the suspended feeding mechanism for wheel hub painting according to this utility model embodiment has a reasonable structure. By adjusting the linkage between the column rod 2 and the connecting rod 3, it can switch between ground and suspended modes, breaking through the limitations of traditional mechanisms. It can simultaneously transport no less than four sets of wheel hubs, significantly improving efficiency compared to traditional mechanisms. The elastic clip 42 and limiting components ensure structural stability and precision. The threaded connection of the axle seat facilitates disassembly and assembly to adapt to wheel hubs of different specifications. It is also compatible with automation upgrades, improves the uniformity of spraying, and has strong overall practicality.
