Description

Technical Field

[0001] This utility model belongs to the field of bumper manufacturing technology, and relates to an auxiliary structure for bumper painting and material cutting. Background Technology

[0002] Car bumpers serve multiple functions, including safety protection, vehicle decoration, and improving aerodynamics. From a safety perspective, they act as a buffer in low-speed collisions, protecting the front and rear of the vehicle; they also offer some protection to pedestrians in accidents. From an aesthetic perspective, they are decorative, becoming an important component in enhancing the car's appearance; furthermore, car bumpers also contribute to aerodynamics.

[0003] One of the processes involved in bumper manufacturing is painting, which involves spraying several layers of paint onto the bumper surface for protection and aesthetic purposes. During painting, the bumper is placed on a bumper bracket, which is then cyclically rotated to perform the hanging, painting, drying, and removal operations in sequence. Typically, a bumper bracket consists of two support rods and at least one anti-rotation rod. The support rods pass through holes in the bumper and also have anti-slip discs that abut against the underside of the bumper. The top of the bumper fits onto the support rods, with its underside abutting against the anti-slip discs, and its bottom or inner bottom abutting against the anti-rotation rod. This ensures a stable connection between the bumper and the bumper bracket. Removing the bumper requires two workers or one worker using both hands to simultaneously operate the top of the bumper and separate it from the support rods. However, due to the large size and weight of the bumper, removing it is relatively inconvenient. Utility Model Content

After the bumper stops at the designated position, the worker manually moves the telescopic column. During the movement, the top of the lifting arm is slightly lower than the top of the grille hole, and the bumper does not affect the movement of the lifting arm. When the lifting arm reaches its maximum stroke, the drive mechanism drives the telescopic column upward, and the lifting arm also lifts the bumper upward. This allows the bumper to be directly separated from the support rod, or assisted in separating the bumper from the support rod. During separation, it is preferable for the worker to use their hand to apply force to the top of the bumper. This not only improves the positional stability of the bumper, but also reduces the burden on the worker's weight after the bumper is separated from the bumper bracket, reducing the workload and preventing damage to the bumper, thus improving the yield rate.

The same or similar reference numerals in the drawings represent the same or similar parts.

[0032] An auxiliary structure for bumper painting and material cutting, such as Figures 1 to 10 As shown, it includes:

[0033] Support rail 1, wherein two support rails are arranged in parallel;

[0034] The movable base plate 2 has a sliding seat 3 at its bottom that is slidably connected to the two support rails 1 respectively;

[0035] Support column 4 is provided on the top of the movable base plate 2, and the top of the support column 4 has a telescopic hole with a rectangular cross-section.

[0036] Telescopic column 5, the outer wall of the telescopic column 5 is movably attached to the inner wall of the telescopic hole, and the support base plate is provided with a drive mechanism for driving the telescopic column 5 to rise and fall.

[0037] A lifting frame 6 is disposed on top of the telescopic column 5. Two lifting arms 7 are provided on the side of the lifting frame 6. When the bumper and bumper bracket are separated, the lifting arms 7 pass through the center grille hole of the bumper and abut against the bottom of the center grille hole. The two lifting arms 7 are respectively located below the two support rods, and the length direction of the telescopic column 5 is parallel to the length direction of the support rods. It should be understood that the bumper, bumper bracket, support rods, and center grille hole of the bumper (used for installing the center grille) are not the contents claimed in this application, and are mentioned again only for illustrative purposes; furthermore, the structure of this application is only applicable to bumpers with center grille holes.

[0038] The top of the lifting arm 7 is provided with a first termination part 8, which abuts against the outside of the bumper.

[0039] The lifting frame 6 is also provided with an auxiliary arm 9 on its side. The auxiliary arm 9 abuts against the bottom of the bumper, and the top of the auxiliary arm 9 is provided with a second termination part 10, which abuts against the outside of the bumper.

[0040] The top of the support rail 1 is provided with a support groove 11 with an inverted Ω-shaped longitudinal section. The sliding seat 3 is movably attached to the inner wall of the support groove 11. When the bumper and the bumper bracket are separated, one end of the sliding seat 3 abuts against the end of the support groove 11.

[0041] A connecting part 12 is provided between the ends of the two support rails 1, and a first elastic element 13 in an extended state is provided between the connecting part 12 and the movable base plate 2. The movable base plate 2 is located between the first elastic element 13 and the lifting arm 7.

[0042] The driving mechanism includes a driving cavity 14 disposed on the side of the support column 4 away from the lifting arm 7. The side of the driving cavity 14 communicates with the side of the telescopic hole. A driving gear 15 is rotatably disposed in the driving cavity 14. A driven rack 16 that meshes with the driving gear 15 is disposed at the bottom of the telescopic column 5. A rotating handle 17 is disposed on the side of the driving gear 15. A through hole is opened on the side of the driving cavity 14 for the rotating handle 17 to move through. The rotating handle 17 and the telescopic column 5 form an inverted V-shape.

[0043] The rotating handle 17 is hollow, and a transmission rod 18 is movably disposed inside the rotating handle 17. A second elastic element 19, which is continuously compressed, is disposed between the top of the transmission rod 18 and the top of the inner cavity of the rotating handle 17. An elongated movable hole 20 is provided on the side of the rotating handle 17. An L-shaped locking part 21 is provided on the side of the transmission rod 18. The bottom end of the locking part 21 faces the driving cavity 14, and both sides are movably fitted against the inner wall of the movable hole 20. A locking seat 22 is provided on the top of the driving cavity 14. A locking groove 23 is provided on the top of the locking seat 22 for the free end of the locking part 21 to be engaged. An unlocking handle 24, which is perpendicular to the transmission rod 18, is provided on the side of the transmission rod 18. An elongated hole is provided on the side of the rotating handle 17 for the unlocking handle 24 to move through.

[0044] The top of the locking seat 22 is also provided with a side groove 25 that communicates with the locking groove 23. The depth of the side groove 25 is less than the depth of the locking groove 23. The free end of the locking part 21 is chamfered. When the chamfered part of the locking part 21 moves toward the side groove 25, the bottom of the side groove 25 can act on the chamfered part of the locking part 21 and drive the locking part 21 to move upward.

[0045] The top of the rotating handle 17 is provided with a vertical handle 26 perpendicular to the rotating handle 17, and the unlocking handle 24 is located below the vertical handle 26, and the vertical handle 26 is parallel to the unlocking handle 24.

[0046] This utility model provides an auxiliary structure for bumper painting and unloading. After the bumper is painted, it moves to the support rail 1 and stops for unloading. At this time, the lifting arm 7 and other components are located on the side of the bumper and bumper bracket, without hindering the normal movement of the bumper and bracket. After the bumper stops at the designated position, the worker manually moves the telescopic column 5. During the movement, the top of the lifting arm 7 is slightly lower than the top of the grille hole, and the bumper does not affect the movement of the lifting arm 7. When the lifting arm 7 moves to its maximum stroke, the drive mechanism drives the telescopic column 5 upward, and the lifting arm 7 also lifts the bumper upward. This allows the bumper to be directly separated from the support rod, or assisted in separating the bumper from the support rod. During separation, it is preferable for the worker to use their hand to apply force to the top of the bumper. This not only improves the positional stability of the bumper, but also reduces the burden on the worker's weight after the bumper is separated from the bumper bracket, reducing the workload and preventing damage to the bumper, thus improving the yield rate.

[0047] In the standby state, under the elastic force of the first elastic element 13, the lifting arm 7 and the auxiliary arm 9 are both at a certain distance from the movement trajectory of the bumper and the bumper bracket, so that the bumper and the bumper bracket can move normally and prevent accidents from happening due to accidental operation.

[0048] After the bumper bracket moves to the designated position and stops, the worker manually pushes the vertical handle 26. At this time, the vertical handle 26, the rotating handle 17, the movable base, the lifting frame 6, and the lifting arm 7 all move towards the bumper until the connecting part 12 touches the end of the support groove 11. At this time, the lifting arm 7 passes through the grille hole, and the top of the lifting arm 7 is slightly lower than the top of the grille hole. The auxiliary arm 9 is located below the bumper and slightly lower than the bottom of the bumper. Then, the worker squeezes the vertical handle 26 and the unlocking handle 24, which drives the transmission rod 18 and the locking part 21 to rise until the bottom of the locking part 21 disengages from the locking groove 23. At this time, the vertical handle 26 can be rotated away from the bumper, which drives the drive gear 15 to rotate. During the rotation of the drive gear 15, the drive rack and the telescopic column 5 are driven to rise. At this time, the lifting frame 6, the lifting arm 7, and the auxiliary arm 9 are all raised, and the bumper is separated from the support rod. In this embodiment, it is preferable to have two workers operate simultaneously. One worker operates the vertical handle 26, the rotating handle 17, and other structures with one hand, while holding the bumper with the other (or pulling the bumper upwards as needed). The other worker can operate the bumper with both hands, thus easily and conveniently separating the bumper from the bumper bracket. Since both the lifting arm 7 and the auxiliary arm 9 can lift the bumper upwards, the bumper can be lifted more comprehensively, further preventing deformation or damage, resulting in better operation. Furthermore, the first termination part 8 and the second termination part 10 both abut against the outer side of the bumper. This allows the worker to continue supporting the bumper via the auxiliary arm 9 and the lifting arm 7 while separating it from the bumper bracket, while the first termination part 8 and the second termination part 10 improve positional stability.

[0049] After removing the bumper from the lifting arm 7 and auxiliary arm 9, release the vertical handle 26 and the unlocking handle 24 (the locking part 21 abuts against the bottom of the movable hole 20). Under the gravity of the lifting frame 6, the telescopic column 5 moves downward, simultaneously driving the drive gear 15 and rotating handle 17 to swing towards the lifting frame 6 via the passive rack 16. During the swing, the bottom of the shallower side groove 25 abuts against the inclined part at the bottom of the locking part 21, which drives the locking part 21 to move upward until it completely passes over the side groove 25. Then, the locking part 21 moves downward again, inserting into the locking groove 23. At this point, if the unlocking handle 24 is not operated, the rotating handle 17 and the drive cavity 14 can remain relatively stationary, and the height of the lifting frame 6 and lifting arm 7 can also remain unchanged. This prevents accidental raising of the lifting arm 7 during operation, or even causing the lifting arm 7 and auxiliary arm 9 to collide with the bumper, ensuring operational safety.

[0050] It should also be noted that all terms such as "set up" and similar descriptive words in this application (especially the specification) indicate that two structures have or exist a connection relationship. However, the specific means by which the two are connected are not limited in detail, and are usually conventional connection methods. That is, the means should be understood as prior art and do not need to be elaborated. For example, "m is set up with n" only indicates that structure m has structure n, and whether the two are connected by welding, riveting, adhesive, or integral molding is within the scope of protection of this application. Similarly, "x is rotatably set up with y" only indicates that y and x can rotate relative to each other, and whether the two are connected by a bearing, or whether y directly passes through x and is rotatably connected to x, or other feasible methods, are all within the scope of protection of this application.

[0051] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
