Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive design and manufacturing technology, specifically to an automotive bumper painting fixture. Background Technology
[0002] Car bumpers are protective components installed at the front and rear of a vehicle. Their primary function is to absorb impact forces during low-speed collisions, protecting the vehicle's structure, pedestrians, and critical components (such as headlights and radiators). They are not only safety devices but also serve aesthetic and aerodynamic optimization purposes. The bumpers at the front and rear of a car not only have a decorative function but, more importantly, are safety devices that absorb and mitigate external impacts, protecting the vehicle body and its occupants.
[0003] The prior art publication number CN210187472U discloses a car bumper painting fixture, belonging to the technical field of automotive design and manufacturing. This utility model's car bumper painting fixture includes two connecting legs, with a horizontally arranged connecting shaft fixed to each leg. The connecting shaft has multiple fixed legs and adjustable legs, and multiple angle adjustment holes arranged sequentially along its length, with the hole axis at a different angle from the horizontal direction. A bushing is provided at the end of each adjustable leg, fitting onto the connecting shaft. The mounting hole on the bushing aligns with the angle adjustment hole, and the adjustable leg is connected and fixed to the connecting shaft by a locating pin. The angle and position of the adjustable legs in this utility model's car bumper painting fixture are adjustable. When painting bumpers at different support positions, only the angle and position of the legs need to be adjusted to suit the painting needs of bumpers at different support positions.
[0004] Through the above-described configuration, the existing spraying fixture, by incorporating an adjustable support leg structure, can avoid switching between fixtures in different support positions, significantly reducing labor intensity, increasing production efficiency, enhancing the versatility of the fixture, reducing the development of new fixtures, and lowering production costs. However, the existing spraying fixture has the following drawbacks during operation:
[0005] The existing spraying fixture requires the positioning pin to be slightly pulled out before the distance and angle between the adjustable legs can be adjusted. Furthermore, it requires drilling holes at different positions on the connecting shaft according to different bumper sizes, making adjustment very inconvenient and unable to be quickly adjusted according to the size of the bumper. Utility Model Content
[0006] This utility model aims to provide a car bumper painting fixture, mainly to solve the technical problems of existing technology where adjusting the distance and angle between adjustable legs is very inconvenient, and for bumpers of different sizes, it is also necessary to re-drill holes on the connecting shaft, which is very inconvenient to use.
[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0008] A car bumper painting fixture includes a first leg, a fixed sleeve fixedly connected to one side of the first leg, a first lead screw rotatably connected to the inner wall of one of the fixed sleeves, a rotating rod fixedly connected to the other end of the first lead screw, a movable sleeve sleeved on the outer wall of the rotating rod, a second leg fixedly connected to the surface of the movable sleeve, a second lead screw rotatably connected to the inner wall of the other fixed sleeve, one end of the second lead screw fixedly connected to the rotating rod, and a turntable fixedly connected to the other end of the second lead screw through the first leg, threaded blocks slidably connected to the outer walls of both the first and second lead screws, a rotating groove opened at the upper end of the threaded block, a support rod rotatably connected to the inner wall of the rotating groove, and a rotating assembly installed on the outer wall of the support rod.
[0009] The working principle and beneficial effects of this utility model:
[0010] 1. Working Principle: When the position and angle of the bumper need to be adjusted, first rotate the turntable, which drives the second lead screw to rotate. The second lead screw then drives the first lead screw to rotate via the rotating rod. The threaded blocks on the first and second lead screws move in opposite directions, causing the two support rods to move relative to each other. This allows the insert rod to be inserted into the insert cylinder. Then, adjust the limiting component to disengage the tooth groove from the gear. Next, rotate the support rod to adjust the angle of the two support rods. Then, press the push rod to disengage the fixing rod on the fixing component from the slot, causing the tooth groove to engage with the gear. Finally, rotate the turntable again to move the two support rods away from each other, completing the adjustment of the bumper's position and angle.
[0011] 2. Beneficial effects:
[0012] Existing technology, by setting up an adjustable support leg angle structure, can avoid switching between tooling at different support positions, greatly reducing labor intensity, improving production efficiency, increasing tooling versatility, reducing the development of new tooling, and lowering production costs. However, existing spraying tooling requires slightly pulling out the positioning pin to adjust the distance and angle between adjustable support legs, and also requires drilling holes at different positions on the connecting shaft according to different bumper sizes, making adjustment very inconvenient and unable to be quickly adjusted according to bumper size. This solution sets up a fixed sleeve, a first lead screw, a second lead screw, a movable sleeve, a rotating rod, a threaded block, a rotating component, a limiting component, and a fixed component. By rotating the turntable, the second lead screw drives the first lead screw to rotate through the rotating rod, causing the threaded block to move in opposite directions. Then, by adjusting the fixed component and the limiting component, the toothed groove on the limiting plate disengages from the gear. Finally, by rotating the component, the two support rods are adjusted. It is very convenient to use and can achieve stepless adjustment of the support rods without drilling.
[0013] Preferably, the rotating assembly includes a rotating shaft, one end of which is fixedly connected to the support rod, and the other end of which passes through and is rotatably connected to a threaded block. A gear is fixedly connected to the end of the rotating shaft away from the support rod, and a limiting component for restricting the rotation of the gear is fixedly connected to the upper surface of the threaded block. By setting the rotating assembly, the support rod can be easily rotated, and stepless adjustment of the support rod can be achieved.
[0014] Preferably, the limiting component includes a fixed block, a movable groove on the lower surface of the fixed block, a limiting plate slidably connected to the inner wall of the movable groove, a toothed groove at one end of the limiting plate that meshes with a gear, a limiting spring fixedly connected to the inner wall of the movable groove, and the other end of the limiting spring fixedly connected to the limiting plate. A pull groove is formed on the outer wall of the fixed block, a pull plate slidably connected to the inner wall of the pull groove, and the pull plate fixedly connected to the limiting plate. A fixing groove is formed on one side of the limiting plate, and a fixing component is installed inside the fixing groove. By setting the limiting component, the gear can be limited, preventing the gear from driving the support rod to rotate, thus making the support for the bumper more stable.
[0015] Preferably, the fixing component includes a fixing spring, with a fixing rod fixedly connected to the other end of the fixing spring. The fixing rod is slidably connected to the fixing groove. A slot is formed on the inner wall of the movable groove, and a sliding plate is slidably connected to the inner wall of the slot. A push rod is fixedly connected to one side of the sliding plate, passing through the fixing block and slidably connected thereto. The fixing rod is inserted into the slot and abuts against the sliding plate. By setting the fixing component, the limiting plate can be limited, preventing the tooth groove from springing back after disengaging from the gear and preventing the tooth groove from meshing with the gear.
[0016] Preferably, a support plate is fixedly connected to the side of the fixed sleeve away from the first leg, and the other end of the support plate is fixedly connected to one end of the movable sleeve. The threaded block is slidably connected to the upper surface of the support plate. By setting the support plate, the threaded block can be limited to prevent rotation.
[0017] Preferably, one support rod has a plug sleeve fixedly connected to one side, and the other support rod has a plug rod fixedly connected to one side, with the plug rod inserted into the plug sleeve. This allows the two support rods to rotate synchronously, facilitating the adjustment of the same angle.
[0018] Preferably, rubber pads are fixed to the outer walls of both the pull plate and the push rod to increase the friction between the fingers and the pads. Attached Figure Description

A tube 26 is fixedly connected to one side of one support rod 10, and a tube 27 is fixedly connected to one side of the other support rod 10. The tube 27 is inserted into the tube 26. A rotating assembly is installed on the outer wall of the support rod 10. The rotating assembly includes a rotating shaft 12. One end of the rotating shaft 12 is fixedly connected to the support rod 10, and the other end of the rotating shaft 12 passes through... A threaded block 8 is rotatably connected to it. A gear 13 is fixedly connected to one end of the rotating shaft 12 away from the support rod 10. A limiting component for restricting the rotation of the gear 13 is fixedly connected to the upper surface of the threaded block 8. The limiting component includes a fixed block 11. A movable groove 14 is formed on the lower surface of the fixed block 11. A limiting plate 15 is slidably connected to the inner wall of the movable groove 14. A toothed groove 16 is formed at one end of the limiting plate 15, meshing with the gear 13. A limiting spring 17 is fixedly connected to the inner wall of the movable groove 14. The other end of the limiting spring 17 is fixedly connected to the limiting plate 15. A pull groove 18 is formed on the outer wall of the fixed block 11. A pull plate 19 is slidably connected to the inner wall of the movable groove 14. The pull plate 19 is fixedly connected to the limiting plate 15. A fixing groove 20 is provided on one side of the limiting plate 15. A fixing component is installed inside the fixing groove 20. The fixing component includes a fixing spring 21.

[0027] As can be seen from the above, the specific embodiments of this utility model are as follows:
[0028] When the position and angle of the bumper need to be adjusted, firstly, rotate the turntable 29, causing the second lead screw 7 to rotate. The second lead screw 7 then drives the first lead screw 3 to rotate via the rotating rod 6. The threaded blocks 8 on the first lead screw 3 and the second lead screw 7 move in opposite directions, causing the two support rods 10 to move relative to each other. This allows the insert rod 27 to be inserted into the insert cylinder 26. Then, pull the pull plate 19, causing it to slide inside the pull groove 18. This causes the pull plate 19 to move the limiting plate 15, which then slides inside the movable groove 14. This compresses the limiting spring 17 and disengages the toothed groove 16 on the limiting plate 15 from the gear 13. At this time, the fixing groove 20 on the limiting plate 15 moves the fixing spring 21 and the fixing rod 22, causing... The fixing groove 20 corresponds to the slot 23. Under the action of the rebound force of the fixing spring 21, the fixing rod 22 is inserted into the slot 23, and the fixing rod 22 pushes the slide 24 to move, which in turn pushes the push rod 25 to move, thus fixing the limiting plate 15. Then, the support rod 10 is rotated to adjust the angle of the two support rods 10. Then, the push rod 25 is pressed, which pushes the slide 24 to disengage the fixing rod 22 from the slot 23. At this time, under the action of the rebound force of the limiting spring 17, the limiting plate 15 is pushed to slide inside the movable groove 14, so that the toothed groove 16 on the limiting plate 15 meshes with the gear 13. Then, the turntable 29 is rotated in the opposite direction, so that the two support rods 10 move away from each other, thus supporting the bumper and completing the adjustment of the position and angle of the bumper.
