Description

Technical Field

[0001] The utility model belongs to the technical field of flexible clamping of workpieces and relates to a flexible clamping device for assembling vehicle doors. Background Art

[0002] Door assembly is a crucial and meticulous task in automotive manufacturing and repair, directly impacting the vehicle's safety, sealing, and overall aesthetics. During the manufacturing phase, door assembly, as part of the complete vehicle assembly process, requires the precise installation of a series of components, including the door body, door lock mechanism, hinge assembly, weatherstrip, window regulator, door handle, rearview mirror, and door trim, to ensure a perfect fit between the door and the vehicle body.

[0003] Because car door assembly requires high precision, traditional rigid clamping methods may cause assembly errors due to their inability to adapt to slight deformations of the car door. Flexible clamping, on the other hand, can adaptively adjust according to the actual shape and size of the car door, ensuring precise positioning of the door during assembly and improving assembly accuracy and overall quality.

[0004] During the assembly process of car doors, due to the complex structure of the doors, different accessories need to be installed precisely in specific positions, which often requires workers to frequently adjust their positions to adapt to different assembly requirements. However, this frequent position adjustment not only increases the workers' labor intensity, but may also reduce the efficiency of the assembly work and affect the overall rhythm of the production line. Utility Model Content

[0005] The technical problem to be solved by the present invention is that during the assembly of vehicle doors, due to the complex structure of the vehicle doors, different accessories need to be precisely installed in specific positions, which often requires workers to frequently adjust their positions to adapt to different assembly requirements.

[0027] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0029] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein can be combined with each other.

[0030] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0031] like Figures 1-6 As shown, a flexible clamping device for assembling vehicle doors includes a base plate 1, a support column 11 is rotatably connected to the middle of the upper surface of the base plate 1, a clamping platform 12 is fixed to the top of the support column 11, an adjustment component is provided in the middle of the base plate 1, and the position of the clamping platform 12 can be adjusted, a limiting component is provided in the middle of the base plate 1, which can improve the stability of the adjustment component, and a flexible clamping component is provided in the middle of the upper surface of the clamping platform 12, which can clamp the vehicle door to be assembled.

[0032] The adjusting assembly includes a worm 22 and a worm wheel 25. The motor support plate 2 is fixedly connected to the upper surface of the base plate 1. The worm wheel 25 is fixedly arranged on the outside of the support column 11. The first servo motor 21 is installed on the motor support plate 2. The output end of the first servo motor 21 is fixedly connected to the worm 22. The worm 22 and the worm wheel 25 are engaged with each other. The end of the worm 22 away from the first servo motor 21 is fixedly connected to the connecting shaft 23. The upper surface of the base plate 1 is also fixedly connected to a support member 24. The connecting shaft 23 is rotatably connected to the support member 24. The support member 24 can support the connecting shaft 23 to improve the stability of the connecting shaft 23 and the worm 22.

[0033] The limiting assembly includes a braking gear 3 and a rack plate 33. The braking gear 3 is fixedly arranged on the outer side of the bottom of the support column 11. A support plate 31 is fixedly arranged on the upper surface of the base plate 1. Two guide rods 32 are fixedly connected to the side of the support plate 31 close to the support column 11. The two guide rods 32 are slidably connected to the rack plate 33. A threaded rod 34 is threadedly connected to the middle part of the support plate 31. One end of the threaded rod 34 is rotatably connected to the rack plate 33, and the end of the threaded rod 34 away from the rack plate 33 is fixed to a turntable 35.

[0034] During operation, when the car door needs to be assembled, it can be fixed by a flexible clamping assembly. When the position of the car door needs to be adjusted to cooperate with the completion of the next stage of assembly work, the first servo motor 21 can be driven to work, driving the worm 22 and the connecting shaft 23 to rotate. Because the worm 22 and the worm wheel 25 are engaged with each other, the worm 22 will drive the worm wheel 25 to rotate during the rotation process. The rotation of the worm wheel 25 will drive the support column 11 to rotate relative to the base plate 1. The rotation of the support column 11 can drive the clamping platform 12 to rotate, thereby adjusting the position of the car door. After adjusting the car door to the appropriate position, the first servo motor 21 is turned off to facilitate workers to perform assembly work.

[0035] At the same time, the rotation of the support column 11 will drive the brake gear 3 to rotate synchronously. When the door position on the clamping platform 12 is adjusted appropriately, the teeth of the brake gear 3 can be aligned with the teeth of the rack plate 33. Then stop the operation of the first servo motor 21, and then rotate the turntable 35 to drive the threaded rod 34 to rotate. Since the threaded rod 34 is threadedly connected to the support plate 31, the threaded rod 34 can move toward the support column 11 during the rotation process. At the same time, the rack plate 33 connected to the threaded rod 34 will also move toward the support column 11. The turntable 35 can be stopped until the threaded rod 34 pushes the rack plate 33 to contact and engage with the brake gear 3.

[0036] By adjusting the settings of the components, the position of the car door can be adjusted. When installing different accessories, workers no longer need to frequently adjust their own position to adapt to different assembly requirements, thereby reducing the complexity of the assembly work and alleviating the labor intensity of the workers.

[0037] By setting the limit assembly, after the door position adjustment is completed, the worm 22 can be effectively prevented from being forced to rotate by external force, thereby causing the worm wheel 25 to rotate, making the door position unstable and affecting the normal progress of the assembly work, thereby avoiding wear of the components between the adjustment components and extending the service life of the components.

[0038] like Figure 1 、 Figure 6 、 Figure 7 and Figure 8 As shown, the flexible clamping assembly includes a bidirectional screw rod 4 and a guide column 41. The bidirectional screw rod 4 is rotatably connected to the top of the clamping platform 12, and the guide column 41 is fixed to the top of the clamping platform 12. The bidirectional screw rod 4 and the guide column 41 are symmetrically arranged on the top of the clamping platform 12. The threads at both ends of the bidirectional screw rod 4 have opposite rotation directions. Both ends of the bidirectional screw rod 4 are threadedly connected to a hollow slide 42. The hollow slide 42 is slidably connected to the guide column 41. Multiple groups of spring dampers 43 are provided on the side where the two hollow slides 42 are close to each other. The spring dampers 43 will shrink under the influence of pressure.

[0039] The flexible clamping assembly also includes a second servo motor 5 and a synchronous pulley group 51. The second servo motor 5 is installed on the outer side of the bottom of the clamping platform 12 to provide power for the flexible clamping assembly. One end of the bidirectional screw rod 4 extends to the outside of the clamping platform 12 and is provided with a synchronous pulley group 51. One end of the synchronous pulley group 51 is connected to the bidirectional screw rod 4, and the other end of the synchronous pulley group 51 is connected to the output end of the second servo motor 5. The synchronous pulley group 51 includes a pulley and a synchronous belt. The output end of the bidirectional screw rod 4 and the second servo motor 5 is fixed with a pulley, and a synchronous belt is provided between the two pulleys. The torque output by the second servo motor 5 can be transmitted to the bidirectional screw rod 4 through the synchronous pulley group 51, thereby driving the bidirectional screw rod 4 to rotate.

[0040] During operation, when the car door needs to be clamped, the car door can be placed in the middle of the clamping platform 12, and then the second servo motor 5 is driven to work to drive the bidirectional screw 4 to rotate through the synchronous pulley set 51. The rotation of the bidirectional screw 4 will drive the two hollow slides 42 to move synchronously. At this time, the hollow slide 42 is affected by the guide column 41 to move, so that it slides along the setting direction of the guide column 41, and because the threads at both ends of the bidirectional screw 4 have opposite rotation directions, the rotation of the bidirectional screw 4 can drive the two hollow slides 42 to move closer to each other in the middle of the bidirectional screw 4, until the side of the hollow slides 42 that is close to each other touches the car door, the multiple groups of spring dampers 43 are affected by the irregular shape of the car door and will shrink to varying degrees until the car door is firmly clamped. The operation of the second servo motor 5 can be stopped to complete the flexible clamping of the car door.

[0041] By setting up a flexible clamping component, it can adapt to the irregular shape of the car door and clamp it effectively, thereby reducing the shaking of the car door due to unstable clamping during assembly, which in turn affects the assembly accuracy.

[0042] like Figure 3 、 Figure 4 and Figure 5 As shown, two support rods 6 are fixedly connected to the bottom of the rack plate 33 , and two sliding grooves 61 are defined in the middle of the bottom plate 1 . The bottoms of the two support rods 6 are slidably engaged with the two sliding grooves 61 , respectively.

[0043] During operation, when the rack plate 33 slides on the guide rod 32, it will drive the support rod 6 to move synchronously, and the bottom of the support rod 6 will slide in the middle of the slide groove 61 during the movement. Through the mutual cooperation between the support rod 6 and the slide groove 61, the rack plate 33 can be supported, thereby improving the stability and reliability of the device.
