Description

Technical Field

[0001] The present application relates to the technical field of hangers, and in particular to a hanger for surface treatment of automobile parts. Background Art

[0002] When automobile parts undergo surface treatment (including grinding, polishing, spraying, electroplating, etc.), they need to be hung on hangers so that they can undergo the next surface treatment operation. When existing hangers clamp automobile parts at multiple points through multiple clamping components, since automobile parts may have surfaces with complex shapes and structures, the clamping components need to avoid uneven and unstable parts of the automobile parts and clamp them on relatively flat parts as much as possible. However, the clamping positions of the clamping components on existing hangers are limited, making it difficult to perform adaptive multi-point clamping on automobile parts with complex surfaces. This may result in fewer available clamping components and ultimately too few clamping points, resulting in low clamping reliability and difficulty in adapting to subsequent surface treatment operations.

[0026] Example

[0027] Reference Figures 1-4 The present embodiment provides a hanger for surface treatment of automobile parts, including a suspension component 100. A plurality of mutually parallel guide rails 200 are provided at the bottom of the suspension component 100. A clamping mechanism is slidably provided at the bottom of each guide rail 200. The clamping mechanism is used to clamp the automobile part 400. The clamping mechanism includes two mutually symmetrical clamping components 300, and the height of the clamping components 300 is adjustable.

[0028] In this embodiment, two clamping assemblies 300 on a plurality of guide rails 200 clamp the two sides of the auto part 400 respectively, and multiple sets of clamping assemblies 300 are used to achieve multi-point clamping of the two sides of the auto part 400. At the same time, according to the surface structure of the auto part 400, if the auto part 400 is bent in the horizontal direction (such as Figure 4 As shown), the clamping components 300 can be slid to corresponding positions to fit the surface of the automotive component 400. If the automotive component 400 is uneven in the vertical direction, the height position of the clamping component 300 (i.e., the height position of the clamping point) can be adjusted to clamp a relatively flat position. Therefore, in this embodiment, the clamping component 300 has a certain adjustment range in both the horizontal and vertical directions, so that it can adapt to the automotive component 400 with a complex surface for multi-point effective clamping, thereby ensuring the reliability of clamping.

[0029] As an optional embodiment, the clamping assembly 300 includes a sleeve 310 slidably connected to the bottom of the guide rail 200, a spring 320 is connected to the top of the sleeve 310, a piston 330 is connected to the bottom of the spring 320, the piston 330 is used to slide up and down along the inner wall of the sleeve 310, the bottom of the piston 330 is connected to a connecting rod 340 that movably extends out of the bottom of the sleeve 310, and the bottom of the connecting rod 340 is connected to a clamping frame 350 for clamping the automotive parts 400.

[0030] In this embodiment, when the height position of the clamping point of the clamping assembly 300 needs to be adjusted, the clamping frame 350 serving as the clamping point can be directly pulled up and down, and the connecting rod 340 and the piston 330 move up and down accordingly, and the spring 320 also shortens or lengthens accordingly. When the clamping frame 350 moves to the corresponding height position, the clamping frames 350 on both sides clamp and fix the two sides of the automotive component 400 respectively. At this time, due to the fixing effect of the clamping frame 350 and the automotive component 400, the spring 320 is limited, so that the length of the entire clamping assembly 300 remains unchanged. When the clamping effect of the clamping frame 350 on the automotive component 400 is released, the clamping frame 350 can be reset under the action of the spring 320 for next use. The operation is convenient and fast, and it is convenient for quick clamping.

[0031] As an optional embodiment, the clamping frame 350 includes a connecting arm 351 connected to the bottom of the connecting rod 340, and a horizontally arranged adjusting screw 352 is threaded through the bottom of the connecting arm 351. The end of the adjusting screw 352 close to each other is connected to a suction cup 353 for contacting the surface of the automotive part 400.

[0032] In this embodiment, when clamping, the two clamping components 300 at the same clamping point (i.e., the suction cup 353) on both sides of the auto part 400 are first slid to fit the surface of the auto part 400. If the clamping frame 350 is directly pressed to make the suction cup 353 adsorb and clamp the auto part 400, the pressing force is difficult to control, and the auto part 400 is easily deformed by the clamping. Therefore, the suction cup 353 is first made to fit the surface of the auto part 400, and then the adjusting screws 352 on both sides are screwed in at the same time, thereby evenly applying pressure to the suction cup 353, so that the suction cup 353 gradually presses the auto part 400, reducing the risk of clamping deformation.

[0033] As an optional embodiment, the ends of the adjusting screws 352 that are close to each other are connected to universal bearings 354 , and the adjusting screws 352 are movably connected to the suction cup 353 through the universal bearings 354 .

[0034] In this embodiment, a universal bearing 354 serves as an intermediate movable member between the adjustment screw 352 and the suction cup 353. When the adjustment screw 352 rotates, the suction cup 353 does not rotate with it. This allows the suction cup 353 to press against the automotive part 400 while the adjustment screw 352 rotates to apply axial pressure. Furthermore, the universal bearing 354 allows the automotive part 400 to be manually swung through a predetermined arc after being clamped and secured, facilitating adjustment of the angle of the part 400 to better suit the surface treatment operation.

[0035] As an optional embodiment, a slider 360 is connected to the top of the sleeve 310, and the slider 360 is slidably connected to the bottom of the guide rail 200. A fastening screw 370 is provided on the slider 360, and the fastening screw 370 is used to fix the slider 360 to the corresponding position of the guide rail 200.

[0036] In this embodiment, the sleeve 310 can slide along the guide rail 200 through the slider 360. When it slides to the clamping point, the slider 360 can be fixed to the corresponding position of the guide rail 200 by screwing in the fastening screw 370, thereby preventing the sleeve 310 from sliding due to the reaction force when the adjusting screw 352 is screwed in. There is no need to manually fix the position of the sleeve 310, which reduces the difficulty of operation.

[0037] As an optional embodiment, the suspension assembly 100 includes a suspension beam 110 , a telescopic cylinder 120 is provided at the bottom of the suspension beam 110 , a lifting plate 130 is connected to the bottom of the telescopic cylinder 120 , and a guide rail 200 is provided on the bottom surface of the lifting plate 130 .

[0038] In this embodiment, the suspension beam 110 is used to cooperate with the lifting mechanism (not shown in the figure) to suspend the entire hanger. The telescopic cylinder 120 can drive the lifting plate 130 to move up and down, thereby driving the clamped automotive parts 400 to move up and down to the corresponding surface treatment station.

[0039] As an optional embodiment, a drive motor 140 is provided at the top of the suspension beam 110, and the drive motor 140 is connected to a turntable 150 movably embedded in the bottom of the suspension beam 110 (through a ball bearing), and the telescopic cylinder 120 is connected to the bottom of the turntable 150.

[0040] In this embodiment, the turntable 150 can be driven to rotate by the driving motor 140, thereby driving the telescopic cylinder 120, the clamping assembly 300 and the automotive part 400 below the turntable 150 to rotate as a whole to a certain angle, which is convenient for cooperating with more surface treatment operations and has strong versatility.

[0041] As an optional embodiment, a lifting ring 160 is provided on the top of the suspension beam 110, and the lifting ring 160 facilitates lifting connection with the lifting mechanism.

[0042] The above are only preferred embodiments of the present application and do not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
