Technical Field

[0001] This utility model relates to the field of automotive parts processing equipment technology, and in particular to a flipping fixture for painting automotive parts. Background Technology

[0002] In the automotive parts manufacturing industry chain, the painting process is a core link to improve the corrosion resistance and appearance quality of products. Its processing accuracy and equipment stability directly affect the quality and market competitiveness of the whole vehicle. In the painting production process of automotive parts, the flipping fixture is a key piece of equipment to achieve double-sided painting of parts. Currently, the flipping fixtures on the market generally adopt a clamping structure that combines rigid jaws and fixed extrusion rods.

[0003] A search revealed that Chinese Patent Publication No. CN222903342U discloses a tooling for flipping automotive parts. This utility model uses a moving plate, sleeve, push rod, connecting plate, and clamping plate to prevent automotive parts from shifting during flipping and enhance the stability of clamping automotive parts. It also uses a lifting plate, sleeve, gear, and toothed plate to enable the automotive parts to rotate when moving upwards, thus avoiding interference from the placement platform when the automotive parts are flipped.

[0004] The above-mentioned and existing related technologies often have the following drawbacks: although they can enhance the stability of clamping automotive parts, automotive parts have different shapes, and traditional grippers can only be adapted to one or a few types of parts. Multiple sets of grippers need to be stocked, resulting in high inventory costs and long changeover times, which affects the working efficiency of the device. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that the clamping parts cannot be matched with parts of different shapes. To this end, we propose a flipping tool for painting automotive parts.

[0006] To achieve the above objectives, this application adopts the following technical solution: a flipping fixture for painting automotive parts, comprising: a base, a placement platform, a transmission component and a spraying component provided on the upper end of the base, the placement platform being located in the middle of the transmission component, the spraying component being located above the placement platform, a sliding plate being fitted on the outer surface of the transmission component, a flipping component being provided on the outer surface of the sliding plate, and a clamping component being fitted on the outer surface of the flipping component. The clamping component includes an open box A and an open box B sleeved on the outer surface of the flipping component. The interior of open box A contains an arc-shaped plate and a clamping plate, with the clamping plate located on both sides of the arc-shaped plate. The interior of open box B contains a lead screw and a sliding rod. The two ends of the lead screw have threads with opposite directions of rotation.

An electric push rod A is fixedly mounted on the outer surface of the slider and fixedly connected to the clamping plate. An electric push rod B is fixedly mounted on the inner wall of open box B and fixedly connected to the arc-shaped plate.

[0007] Preferably, the outer surface of the arc-shaped plate is provided with a groove, the size of which is adapted to the size of the electric push rod A.

[0008] Preferably, the transmission component includes a support block disposed on the upper end of the placement platform. Two sets of support blocks are provided, and a bidirectional threaded rod and a support rod are disposed between the two sets of support blocks. The two ends of the bidirectional threaded rod have threads with opposite directions of rotation. One end of one set of support blocks is provided with a motor B. The output end of the motor B passes through the support block and is fixedly connected to the bidirectional threaded rod. A sliding plate is sleeved on the outer surface of the bidirectional threaded rod and the support rod. Two sets of sliding plates are provided, and the two sets of sliding plates are connected to the threads with different directions of rotation at the two ends of the bidirectional threaded rod. The sliding plate is slidably connected to the support rod.

[0009] Preferably, the flipping component includes a rotating shaft A and a rotating shaft B disposed on the outer surface of the slide plate.

[0014] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0015] Reference Figure 1 and Figure 4As shown, this utility model provides a technical solution: a flipping fixture for painting automotive parts, comprising: a base 1, a placement platform 2, a transmission component 3 and a spraying component 6 provided on the upper end of the base 1, the placement platform 2 being located in the middle of the transmission component 3, the spraying component 6 being located above the placement platform 2, a sliding plate 7 being fitted on the outer surface of the transmission component 3, a flipping component 4 being provided on the outer surface of the sliding plate 7, and a clamping component 5 being fitted on the outer surface of the flipping component 4. The clamping component 5 includes an open box A51 and an open box B54 fitted onto the outer surface of the flipping component 4. The interior of the open box A51 contains an arc-shaped plate 52 and a clamping plate 53, with the clamping plate 53 located on both sides of the arc-shaped plate 52. The interior of the open box B54 contains a lead screw 55 and a sliding rod 56. The two ends of the lead screw 55 have threads with opposite directions of rotation. A motor A58 is mounted on the outer surface of the open box B54. The output end of the motor A58 passes through the open box B54 and is fixedly connected to the lead screw 55. A slider 57 is fitted onto the outer surface of the slide rod 56 and the lead screw 55. The slider 57 is threadedly connected to the lead screw 55 and slidably connected to the slide rod 56. An electric push rod A531 is fixed to the outer surface of the slider 57 and is fixedly connected to the clamping plate 53. An electric push rod B521 is fixed to the inner wall of the open box B54 and is fixedly connected to the arc plate 52. When it is necessary to paint the square parts, the electric push rod A531 pushes the clamping plate 53 toward the parts. When the clamping plate 53 is pushed out of the opening box A51, the motor A58 is started, and the motor A58 drives the lead screw 55 to rotate. Since the threads at both ends of the lead screw 55 rotate in opposite directions, the slider 57 moves in opposite directions along the slide rod 56, quickly adjusting the initial distance between the two clamping plates 53 to be slightly larger than the width of the part, thereby realizing the rapid changeover and clamping of parts of different sizes. When it is necessary to paint the round parts, the electric push rod B521 extends, pushing the arc plate 52 out of the opening box A51 to fit the outer contour of the part and achieve circumferential positioning. After the square parts are painted, the motor A58 reverses, causing the slider 57 to return to the initial position, the clamping plate 53 is released, and the electric push rod A531 retracts, causing the clamping plate 53 to return to the opening box A51. After the round parts are painted, the electric push rod B521 retracts, causing the arc plate 52 to return to the opening box A51. By clamping parts of different sizes with the arc plate 52 and the clamping plate 53, the mold changeover time can be shortened and the production efficiency can be improved.

[0016] The outer surface of the arc plate 52 is provided with a slot 522. The size of the slot 522 is adapted to the size of the electric push rod A531. When it is necessary to clamp a round part, the electric push rod B521 moves with the slider 57, so that the electric push rod B521 can move within the slot 522, realizing the precise coordination between the arc plate 52 and the electric push rod B521, and avoiding the arc plate 52 from blocking the movement of the electric push rod B521.

[0017] Reference Figure 2 and Figure 3 As shown in this embodiment: the transmission component 3 includes a support block 32 disposed on the upper end of the placement platform 2. Two sets of support blocks 32 are provided, with a bidirectional threaded rod 33 and a support rod 34 disposed between the two sets of support blocks 32. The two ends of the bidirectional threaded rod 33 have threads with opposite directions of rotation. One end of one set of support blocks 32 is provided with a motor B31. The output end of the motor B31 passes through the support block 32 and is fixedly connected to the bidirectional threaded rod 33. A sliding plate 7 is sleeved on the outer surface of the bidirectional threaded rod 33 and the support rod 34. Two sets of sliding plates 7 are provided, with the two sets of sliding plates 7 having different directions of rotation with the two ends of the bidirectional threaded rod 33. The slide plate 7 is slidably connected to the support rod 34 via a threaded connection. When the motor B31 starts, the output end of the motor B31 drives the bidirectional threaded rod 33 to rotate. Since the threads at both ends of the bidirectional threaded rod 33 rotate in opposite directions, when the bidirectional threaded rod 33 rotates clockwise, the slide plate 7 connected to the left-hand thread moves to the left, and the slide plate 7 connected to the right-hand thread moves to the right; conversely, when it rotates counterclockwise, the two sets of slide plates 7 move in opposite directions, achieving synchronous movement towards or away from each other. The movement of the slide plate 7 drives the lateral displacement of the flipping component 4 and the clamping component 5, thereby adjusting the distance between the clamping components 5 and achieving compatibility with parts of different sizes.

[0018] The flipping component 4 includes a rotating shaft A42 and a rotating shaft B43 disposed on the outer surface of the slide plate 7. The rotating shaft A42 is rotatably connected to the slide plate 7. A motor C41 is disposed at one end of the rotating shaft A42. Gears are sleeved on the outer surfaces of both the rotating shaft A42 and the rotating shaft B43. The two sets of gears mesh with each other. An electric push rod C44 is fixed to one end of the rotating shaft B43 through the slide plate 7. The electric push rod C44 is fixedly connected to the open box A51 and the open box B54. When the motor C41 is started, the motor C41 drives the rotating shaft A42 to rotate. The rotating shaft A42 and the slide plate 7 are rotatably connected through bearings to ensure smooth rotation. When the rotating shaft A42 rotates, it drives the rotating shaft B43 to rotate synchronously in the opposite direction through gear meshing, thereby allowing the open box A51 and the open box B54 to flip. The electric push rod C44 can adjust the distance between the open box A51 and the open box B54 and the parts, adapting to the size of different parts and improving the flexibility of the tooling.

[0019] Reference Figure 3 As shown in this embodiment: the placement platform 2 includes an electric push rod D21 set on the upper end of the base 1. The upper end of the electric push rod D21 is fixed with a placement plate 22. When the electric push rod D21 is activated, the placement plate 22 is driven to rise and fall vertically, thereby realizing the height adjustment of the placement plate 22. When the clamping component 5 clamps parts of different thicknesses, the electric push rod D21 can adjust the height of the placement plate 22 to ensure that the center of the part is aligned with the rotation axis of the flipping component 4, and to avoid the center of gravity shift during flipping due to height deviation.

[0020] Reference Figure 2As shown in this embodiment: the spraying component 6 includes a telescopic column 61 set on the upper end of the base 1. One end of the telescopic column 61 is provided with a nozzle 62. When the height of the placement plate 22 of the placement platform 2 is adjusted, the height of the nozzle 62 is adjusted synchronously by the telescopic column 61 to ensure that the distance between the nozzle 62 and the surface of the component is constant.

[0021] Working principle: First, place the automotive parts on the placement plate 22. Then, activate the electric push rod D21 to vertically raise and lower the placement plate 22, thus adjusting its height. Simultaneously, the telescopic column 61 adjusts the height of the nozzle 62 to ensure a constant distance between the nozzle 62 and the surface of the parts. Motor B31 starts, and its output drives the bidirectional threaded rod 33 to rotate. When the threads at both ends of the bidirectional threaded rod 33 rotate in opposite directions, the two sets of sliding plates 7 move towards each other. The movement of the sliding plates 7 causes the flipping component 4 and the clamping component 5 to shift laterally, thereby adjusting the spacing between the clamping components 5 and enabling the clamping of parts of different sizes. In a compliant configuration, when the square component needs to be clamped after displacement to a certain position, the electric push rod A531 pushes the clamping plate 53 towards the component. After the clamping plate 53 is pushed out of the open box A51, the motor A58 is started, driving the lead screw 55 to rotate. Since the threads at both ends of the lead screw 55 rotate in opposite directions, the slider 57 moves towards each other along the slide rod 56, quickly adjusting the initial distance between the two clamping plates 53 to be slightly greater than the width of the component. The electric push rod B521 can then move within the slot 522, achieving precise coordination between the arc plate 52 and the electric push rod B521, preventing the arc plate 52 from obstructing the electric push rod B521. The movement of 521 enables rapid shape change and clamping of parts of different sizes. When painting round parts, the electric push rod B521 extends, pushing the arc plate 52 out of the opening box A51 to conform to the outer contour of the part and achieve circumferential positioning. After painting the square parts, the motor A58 reverses, causing the slider 57 to return to its initial position, the clamping plate 53 releases, and the electric push rod A531 retracts, causing the clamping plate 53 to return to the opening box A51. After painting the round parts, the electric push rod B521 retracts, causing the arc plate 52 to return to the opening box A51, where it is clamped by the arc plate 52 and the clamping plate 53. Different sized parts can shorten mold change time and improve production efficiency. The electric push rod C44 can adjust the distance between the open box A51 and open box B54 and the parts, adapting to the size of different parts and improving the flexibility of the tooling. After clamping, the motor C41 is started, and the motor C41 drives the rotating shaft A42 to rotate. The rotating shaft A42 and the slide plate 7 are rotatably connected through bearings to ensure smooth rotation. When the rotating shaft A42 rotates, it drives the rotating shaft B43 to rotate synchronously in the opposite direction through gear meshing, so that the open box A51 and open box B54 can be flipped, thereby realizing the flipping tooling for painting.

[0022] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
