[0015] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be 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 utility model and are not used to limit the present utility model.
[0016] Refer to Figures 1 - 3 A two-way hemming height detection fixture for an automobile sheet metal part as shown, which includes a bottom plate 1. A first positioning post 2 is fixedly connected to the middle of the bottom plate 1. Right-angle positioning blocks 3, a limiting component and a hemming height testing mechanism are arranged on both sides of the bottom plate 1. A cylinder 6 and a linear module 7 are arranged below the bottom plate 1. A second positioning post 701 is fixedly connected to the moving table of the linear module 7. The limiting component includes a guide block 401, a limit rod 402 and a slide block 403. The height testing mechanism includes a motor 501, a rotating shaft 502 and a collar 503. A deviation correction groove 5021 and a card slot 5022 are formed on the rotating shaft 502. A flat plate 504 and a locking screw 505 are arranged beside the rotating shaft 502. The locking screw 505 is arranged corresponding to the card slot 5022. The slide block 403 is slidably connected to the bottom plate 1, and the slide block 403 is fixedly connected to the piston rod of the cylinder 6.
[0017] A strip-shaped groove is formed in the bottom plate 1, and the second positioning post 701 is located in the strip-shaped groove. The strip-shaped groove can make way for the sliding of the second positioning post 701.
[0018] The right-angle positioning block 3 and the guide block 401 are both fixedly connected to the bottom plate 1. The limiting rod 402 is fixedly connected to the slider 403. A jack is provided on the guide block 401, and the limiting rod 402 is slidably connected to the jack. The jack can guide the sliding of the limiting rod 402.
[0019] The motor 501 is fixedly connected to the bottom plate 1. The rotating shaft 502 is fixedly connected to the output end of the motor 501. The collar 503 is slidably connected to the rotating shaft 502. A convex block corresponding to the deviation-correcting groove 5021 is provided on the collar 503. The deviation-correcting groove 5021 is opened to prevent the collar 503 from deflecting relative to the rotating shaft 502.
[0020] The flat plate 504 is integral with the collar 503. The flat plate 504 is used to rotate and horizontally scan the bent section of the automobile sheet metal to detect whether the height of its bent section exceeds the height. The locking screw 505 is threadedly connected to the collar 503. The locking screw 505 is used to fix the collar 503 in cooperation with the card slot 5022.
[0021] The working principle of the present utility model is as follows: Before the present utility model is used, first, the position of the second positioning post 701 is adjusted according to the size of the V angle of the automobile sheet metal. The position can be adjusted by driving the second positioning post 701 to slide through the linear module 7. Then, the height of the collar 503 is adjusted according to the height of the bent section of the automobile sheet metal.
[0022] When the present utility model is in use, first, the piston rod of the air cylinder 6 extends, and the limiting rod 402 is withdrawn from the guide block 401. Then, the automobile sheet metal is placed on the bottom plate 1 along the right-angle positioning block and the guide block 401. If the automobile sheet metal can be placed flat on the bottom plate 1, the V angle test is qualified; otherwise, it is unqualified. After that, the piston rod of the air cylinder 6 retracts, and the limiting rod 402 is inserted into the guide block 401 to limit the automobile sheet metal. Then, the motor 501 drives the rotating shaft 502 to rotate. If the flat plate 504 can sweep across the bent section, the height test is qualified; otherwise, it is unqualified.
[0023] The above embodiments are used to further illustrate the present utility model, but do not limit the present utility model to these specific embodiments. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model should be understood to be within the protection scope of the present utility model.
