Description

Technical Field

[0001] The present application relates to the technical field of wheel processing, and in particular to a turning and lifting device and method for processing passenger car wheels. Background Art

[0002] Wheel processing is a crucial step in the bus manufacturing industry. During the bus wheel processing process, in order to meet the needs of multi-directional operations on different parts of the wheel, such as the inside and outside, such as grinding, spraying, and testing, it is necessary to use flipping equipment to achieve a 180° flip around the axis of the wheel. Traditional wheel turning equipment has been used to some extent in the field of bus wheel processing. Its common structure uses a reversible support platform or clamping arm to directly support and turn the wheel. The specific working principle is that the turning component is driven by a rotating shaft, which directly acts on the wheel to complete the turning action. However, when it comes to large and heavy bus wheels, significant shortcomings have gradually emerged. Existing flipping equipment needs to clamp the wheel first, then lift it, and finally flip it. First, an additional clamping structure is required. Secondly, lifting the wheel requires applying a large lifting force to overcome the entire gravity of the wheel, which consumes more energy. In addition, the heavy weight of the wheel places higher demands on the clamping structure. Finally, when flipping, the rotating shaft needs to withstand the torque generated by the gravity of the wheel. If it is under this large load torque for a long time, the rotating shaft is prone to deformation or even breakage.

[0003] Based on this, there is an urgent need for a device and method for providing stable and efficient turning of bus wheels. Summary of the Invention

[0009] In some embodiments, the flipping mechanism further includes: a dual-axis motor, disposed on the flipping seat; two screw rods, symmetrically disposed on both sides of the dual-axis motor, the two screw rods having opposite thread directions, and the two moving blocks are separately disposed on the corresponding screw rods.

[0010] In some embodiments, the limiting mechanism also includes: a rotating shaft, which is arranged at the bottom of the V-block and passes through the flip seat, and a limiting protrusion is provided at the end of the rotating shaft away from the V-block; a plane bearing, one side of which is connected to the flip seat and the other side is connected to the V-block.

[0016] Compared with the prior art, the above technical solution provided by this application includes at least the following technical effects: The present application provides a turning and lifting device for processing passenger vehicle wheels, which efficiently and stably turns passenger vehicle wheels. The lifting mechanism is activated to raise the turning platform to the same height as the wheel conveying equipment. The wheel to be turned is conveyed horizontally to the moving block and contacts the V-block, achieving initial wheel positioning. The turning mechanism is then activated to rotate the turning seat, rotating the wheel along a vertical plane, turning it from a horizontal state to a vertical state. This in turn drives the two moving blocks to move to the sides, reserving space for subsequent wheel rotation and preventing obstruction of wheel rotation. One of the moving blocks drives the shifting frame to move, which in turn drives the V-block to rotate, thereby driving the vertical wheel to rotate 180° along the horizontal plane. At this point, the wheel is in a vertical state and its orientation is adjusted. This in turn drives the two moving blocks to move back to the wheel position, driving the turning seat and the moving block to rotate in opposite directions along the vertical plane, turning the wheel from a vertical state to a horizontal state, completing the wheel turning action. During the flipping process of this device, the wheel is flipped with a point outside the wheel body itself as the center of the circle, so that the wheel changes from a horizontal state to a vertical state. In this flipping method, the wheel always maintains partial contact with the flip seat during the flipping process, the gravity that needs to be overcome is relatively small, and no additional clamping structure is required. In the traditional wheel flipping operation, a large lifting force needs to be applied to first lift the wheel off the supporting surface and then rotate it along the rotating axis. The driving requirements of this device for the power source are significantly smaller than those of traditional equipment, and the traditional rotating shaft needs to withstand the torque generated by the weight of the wheel. It is easy to deform or even break under the action of large load torque for a long time. This device rotates after the wheel is flipped to a vertical state. In this state, a smaller force can be used to complete the rotation of the wheel.

DETAILED DESCRIPTION

[0020] In order to more clearly understand the above-mentioned objects, features and advantages of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other in the absence of conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0022] Refer to the following Figures 1 to 11 The present invention describes a flipping and lifting device and method for processing passenger car wheels provided in some embodiments of the present application.

[0023] like Figure 1As shown, the turning and lifting device for processing passenger car wheels provided in some embodiments of the present application includes a support base 10, two lifting mechanisms 100, a turning mechanism 200, a limiting mechanism 300 and a steering mechanism 400. Among them, two lifting mechanisms 100 are symmetrically arranged on the supporting base 10 for lifting the horizontal wheel; the flipping mechanism 200 is connected to the lifting mechanism 100, and the flipping mechanism 200 includes: a flip seat 220, which is arranged on the lifting mechanism 100, and the flip seat 220 rotates along the vertical plane to flip the horizontal wheel to the vertical state; two moving blocks 260 are symmetrically arranged on the flip seat 220 for carrying the horizontal wheel, and the two moving blocks 260 can move relative to each other; a limiting mechanism 300 is arranged on the flipping mechanism 200, and the limiting mechanism 300 includes: a V-shaped block 310, which contacts the wheel, and the V-shaped block 310 can limit the horizontal wheel and support the vertical wheel; a steering mechanism 400 is arranged on the flip seat 220, and the steering mechanism 400 includes: a toggle frame 440, which is fixedly connected to one of the moving blocks 260, and the moving block 260 drives the toggle frame 440 to move, driving the V-shaped block 310 to drive the vertical wheel to rotate along the horizontal plane.

[0024] In this embodiment, the lifting mechanism 100 adjusts the flip platform to the same height as the wheel conveying equipment to ensure that the wheel can be accurately conveyed. The to-be-flipped wheel is conveyed to the moving block 260 in a horizontal state and contacts with the V-block 310 to achieve preliminary positioning of the wheel. The flipping mechanism 200 is started to rotate the flip seat 220, rotate the wheel along the vertical plane, and flip it from a horizontal state to a vertical state, thereby driving the two moving blocks 260 to move to both sides, reserving space for subsequent rotation of the wheel to prevent interference with the wheel rotation. One of the moving blocks 260 drives the toggle frame 440 to move, and the toggle frame 440 drives the V-block 310 to rotate, thereby driving the vertical wheel to rotate 180° along the horizontal plane. At this time, the wheel is in a vertical state and the orientation is adjusted, thereby driving the two moving blocks 260 to move back to the wheel position, driving the flip seat 220 and the moving block 260 to rotate in opposite directions along the vertical plane, flipping the wheel from a vertical state to a horizontal state, and completing the wheel flipping action.

[0025] In some possible embodiments, such as Figure 2 As shown, each lifting mechanism 100 includes: a support frame 110, which is arranged on the support base 10, and has a movable cavity inside the support frame 110; two guide rails 120, which are symmetrically arranged on both sides of the movable cavity of the support frame 110; a hydraulic cylinder 130, which is arranged on the support frame 110; a telescopic rod 131, which is arranged at one end of the hydraulic cylinder 130, and the telescopic rod 131 is located in the movable cavity; a lifting block 140, which is arranged at the end of the telescopic rod 131 away from the hydraulic cylinder 130, and the lifting block 140 includes two grooves, each groove cooperates with the corresponding guide rail 120; and a support arm 150, which is fixedly connected to the lifting block 140.

[0026] In this embodiment, in the initial state of the hydraulic cylinder 130, the telescopic rod 131 is in an extended state, the lifting block 140 is in the lower part of the movable cavity, and the support arm 150 drives the moving block 260 to be in a lower position. The height of the moving block 260 is adjusted according to the height of the wheel conveying equipment to ensure that the wheel can be accurately conveyed to the moving block 260. That is, by starting the hydraulic cylinder 130, the hydraulic cylinder 130 converts hydraulic energy into mechanical energy, causing the telescopic rod 131 to contract, and the lifting block 140 moves upward along the guide rail 120. Since the support arm 150 is fixedly connected to the lifting block 140, the support arm 150 also moves upward, so that the moving block 260 on the top of the support arm 150 adapts to the height of the wheel conveying equipment.

[0027] In this design, the support frame 110 provides a stable support structure, and the two symmetrically designed guide rails 120 cooperate with the grooves of the lifting block 140 to ensure the stability and accuracy of the lifting block 140 during the up and down movement, reduce the risk of failure due to shaking, and improve the reliability of the device.

[0028] In some possible embodiments, such as Figure 3 、 Figure 4 As shown, the flipping mechanism 200 also includes: a support seat 210, which is arranged on two support arms 150, and a support shaft for supplying rotation to the flipping seat 220 is provided on the support seat 210, and the flipping seat 220 has a moving space inside; the cylinder 230 is provided with two rotating seats, which are arranged at both ends of the cylinder 230, one rotating seat is connected to the support seat 210, and the other rotating seat is connected to the flipping seat 220, and the cylinder 230 is used to drive the flipping seat 220 to rotate in both directions along the support shaft.

[0029] When the wheel is in the upright position, the cylinder 230 is extended. Since the rotating seat at one end of the cylinder 230 is connected to the support seat 210 and the rotating seat at the other end is connected to the tilting seat 220, the extension of the cylinder 230 will generate a thrust, pushing the tilting seat 220 to rotate 90° around the support axis. Then the tilting seat 220 gradually rotates from the vertical position to the horizontal position, and the moving block 260 and the wheel are flipped from the horizontal position to the vertical position, completing the rotation of the wheel in the vertical direction. At this time, the V-shaped block 310 on the tilting seat 220 bears the weight of the wheel. After the steering mechanism 400 completes the rotation of the wheel in the horizontal direction, it is necessary to flip the wheel from the vertical position back to the horizontal position. The cylinder 230 contracts, pulling the tilting seat 220 to rotate 90° in the opposite direction around the support axis, and the wheel returns to the horizontal position, completing the wheel flipping action.

[0030] In some possible embodiments, such as Figures 3 to 5 As shown, the flip mechanism 200 also includes: a dual-axis motor 240, which is arranged on the flip seat 220; two screw rods 250, which are symmetrically arranged on both sides of the dual-axis motor 240, with the thread directions of the two screw rods 250 opposite, and two moving blocks 260 are respectively arranged on the corresponding screw rods 250.

[0031] In this embodiment, in the initial state, the distance between the two moving blocks 260 is small, so that the two moving seats can carry the wheels. When the wheels need to rotate in the horizontal direction, the two moving blocks 260 need to be moved to both sides to reserve space for the wheel rotation, that is, by starting the dual-axis motor 240, the two output shafts of the dual-axis motor 240 rotate at the same time, driving the screw rods 250 on both sides to rotate synchronously. Since the thread directions of the two screw rods 250 are opposite, the two moving blocks 260 that are threaded with the screw rods 250 will make synchronous opposite linear motions along the screw rods 250, thereby moving away from the wheels. In this process, the wheels complete the rotation in the horizontal direction. After the flipping is completed, the moving blocks 260 need to restore the wheel position to provide support for the rotation of the wheel in the vertical direction, that is, the dual-axis motor 240 controls the screw rod 250 to rotate in the opposite direction.

[0032] In some possible embodiments, such as Figures 6 to 11 As shown, the limiting mechanism 300 also includes: a rotating shaft 311, which is arranged at the bottom of the V-block 310 and passes through the flip seat 220, and a limiting protrusion is provided at the end of the rotating shaft 311 away from the V-block 310; a plane bearing 320, one side of which is connected to the flip seat 220 and the other side is connected to the V-block 310; the steering mechanism 400 also includes: a one-way bearing 410, which is connected to the limiting protrusion of the rotating shaft 311; a connecting sleeve 420, which is fixedly arranged on one side of the one-way bearing 410; a shift post 430, which is arranged on the connecting sleeve 420; a V-shaped groove is provided in the toggle frame 440, and the other end of the shift post 430 is located in the V-shaped groove, and the toggle frame 440 moves in the moving space of the flip seat 220, and the shift post 430 drives the rotating shaft 311 and the V-block 310 and the wheel on its top to rotate 180°.

[0033] In this embodiment, after the turning mechanism 200 turns the wheel to a vertical state, the plane bearing 320 bears the weight of the wheel and the V-shaped block 310. When the wheel needs to be rotated 180 degrees, the dual-axis motor 240 drives the moving block 260 to move to both sides. Since one of the moving blocks 260 is connected to the toggle frame 440, the moving block 260 drives the toggle frame 440 to move within the moving space of the turning seat 220. Since the other end of the shifting post 430 is located in the V-shaped groove of the toggle frame 440, as the toggle frame 440 moves, the shifting post 430 performs a circular motion under the action of the V-shaped groove, and the shifting post 430 drives the connecting sleeve 420 to rotate, and the connecting sleeve 420 drives The rotating shaft 311 rotates, and under the action of the one-way bearing 410, the rotating shaft 311 drives the V-block 310 and the wheel on top of it to rotate together. A flat bearing 320 is provided at the bottom of the V-block 310 to ensure the smooth rotation of the V-block 310. As the toggle frame 440 continues to move, the wheel finally rotates 180°. After the rotation is completed, the dual-axis motor 240 drives the moving block 260 to move back to the wheel position, and the toggle frame 440 moves accordingly, and the connecting sleeve 420 and the shifting column 430 rotate and reset accordingly. Under the action of the one-way bearing 410, the rotating shaft 311 and the V-block 310 will not rotate at this time, completing the flipping action of the wheel in the horizontal plane.

[0034] It should be noted that the one-way bearing 410 can rotate freely in one direction, but will be locked in the opposite rotation direction; when the two moving blocks 260 move toward the diverging direction, the shift column 430 performs a circular motion in the shifting frame 440, driving the connecting sleeve 420 and the one-way bearing 410 to rotate clockwise, and the one-way bearing 410 is in a locked state when rotating clockwise, and the one-way bearing 410 will drive the rotating shaft 311 to rotate; when the two moving blocks 260 move toward the approaching direction, the connecting sleeve 420 and the one-way bearing 410 rotate counterclockwise, and the one-way bearing 410 is in a free state at this time. At this time, the rotating shaft 311 will not rotate when the one-way bearing 410 rotates, and the V-block 310 remains in this position.

[0035] In some possible embodiments, such as Figure 5 As shown, each moving block 260 has a plurality of rollers 261 , and each roller 261 is capable of rotating.

[0036] In this embodiment, multiple rollers 261 are evenly distributed on the moving block 260. When the wheel moves to the moving block 260 through the driving device, the wheel and the surface of the moving block 260 will come into contact and move relative to each other. The sliding friction between the wheel and the moving block 260 is converted into rolling friction by the multiple rollers 261, reducing the resistance received by the wheel when entering the moving block 260, so that the wheel can move to the moving block 260 more smoothly.

[0037] In some possible embodiments, the V-shaped block 310 has a V-shaped receiving space, and an anti-slip pad is provided in the V-shaped receiving space.

[0038] In this embodiment, the V-shaped accommodation space of the V-block 310 is "V"-shaped. The V-shaped structure can better adapt to circular objects of different diameters. Regardless of the diameter of the wheel, a suitable support point can be found in the V-shaped groove. By adding an anti-slip pad in the V-shaped groove, the anti-slip pad has a high friction coefficient, so that the wheel enters the V-shaped accommodation space and the anti-slip pad is in direct contact with its surface, increasing the friction between the two, preventing the wheel from sliding in the V-shaped groove, and improving the safety and reliability of the device.

[0039] In some possible embodiments, the bottom surface of the support base 10 has an anti-slip pad.

[0040] In this embodiment, the support base 10 provides a stable support foundation for the device. When the support base 10 is placed on the ground, the anti-slip pad contacts the ground, generating a large friction force. This friction force can resist the action of external forces on the support base 10, keeping it stationary and improving the overall stability of the device.

[0041] The present application also provides a method for turning over a turning and lifting device for processing a passenger car wheel, comprising the following steps: Step 1: The wheel is transported to the moving block 260 in a horizontal state and contacts the V-shaped block 310; Step 2: Start the oil cylinder 230 to drive the flip seat 220 to rotate 90 degrees along the support axis of the support seat 210, flipping the wheel from a horizontal state to a vertical state; Step 3: The dual-axis motor 240 drives the moving block 260 to move the shifting frame 440, so that the shifting post 430 moves in the V-shaped slot of the shifting frame 440, driving the rotating shaft 311 to rotate 180°, thereby driving the vertical wheel supported by the V-shaped block 310 to rotate 180° along the horizontal plane; Step 4: Start the oil cylinder 230 again to drive the flip seat 220 to rotate -90 degrees along the support axis of the support seat 210, flipping the wheel from a vertical state to a horizontal state, so that the wheel completes the flipping operation.

[0042] In this method, the wheel is flipped with a point outside the wheel body itself as the center of the circle, so that the wheel changes from a horizontal state to a vertical state. In this flipping method, the wheel always maintains partial contact with the flip seat 220 during the flipping process, the gravity to be overcome is small, and no additional clamping structure is required. In the traditional wheel flipping operation, a large lifting force needs to be applied to first lift the wheel off the support surface and then rotate it along the rotation axis. The driving requirements of this device for the power source are significantly smaller than those of traditional equipment, and the traditional rotating shaft needs to withstand the torque generated by the weight of the wheel. It is easy to deform or even break under the action of large load torque for a long time. This device rotates after the wheel is flipped to a vertical state. In this state, a smaller force can be used to complete the rotation of the wheel.

[0043] When the turning and lifting device and method for processing a bus wheel are in operation, the bus wheel is transported to the moving block 260 in a horizontal state and contacts the V-block 310. The V-block 310 performs a preliminary limit on the wheel. At this time, the weight of the wheel is borne by the moving block 260, thereby activating the hydraulic cylinder 130. The hydraulic cylinder 130 converts hydraulic energy into mechanical energy, causing the telescopic rod 131 to contract, driving the lifting block 140 to move upward along the guide rail 120. Since the support arm 150 is fixedly connected to the lifting block 140, the support arm 150 also moves upward, thereby driving the lifting block 140 placed on the guide rail 120. The wheel on the moving block 260 is lifted upward until it reaches the required height, thereby starting the extension of the oil cylinder 230. The thrust generated by the oil cylinder 230 pushes the flip seat 220 to rotate 90 degrees around the support axis, so that the flip seat 220 gradually rotates from a vertical state to a horizontal state. At the same time, the moving block 260 and the wheel flip from a horizontal state to a vertical state, completing the rotation of the wheel in the vertical direction. At this time, the weight of the wheel is transferred to the V-shaped block 310, thereby starting the dual-axis motor 240. The two output shafts of the dual-axis motor 240 rotate at the same time, driving the threads on both sides in opposite directions. The screw rod 250 rotates synchronously. Since the two moving blocks 260 are respectively arranged on the corresponding screw rod 250 and the thread directions are opposite, the two moving blocks 260 will make synchronous opposite linear motions along the screw rod 250, thereby moving away from the wheel and reserving space for the wheel rotation. During the movement of the moving block 260, the toggle frame 440 is driven to move in the moving space of the flip seat 220. Since the shifting post 430 is located in the V-shaped groove of the toggle frame 440, as the toggle frame 440 is used, the shifting post 430 makes a circular motion under the action of the V-shaped groove, driving the connecting sleeve 420 to rotate, and the connecting sleeve 420 is connected. The connecting sleeve 420 drives the rotating shaft 311 to rotate. Under the action of the one-way bearing 410, the rotating shaft 311 drives the V-block 310 and the wheel on its top to rotate 180°, completing the rotation of the wheel in the horizontal direction. At this time, the dual-axis motor 240 drives the screw rod 250 to rotate in the opposite direction, so that the two moving blocks 260 move back to the wheel position. The oil cylinder 230 is started again to drive the flip seat 220 to rotate 90° in the opposite direction along the support axis of the support seat 210, flipping the wheel from a vertical state to a horizontal state. The wheel completes the flipping operation and returns to the initial position to enter the next process.
