[0022] This part will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The function of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it should not be construed as a limitation on the protection scope of the present utility model.
[0023] Referring to Figures 1-4 , an embodiment of a processing fixture for the sealing surface of an automobile engine hood cover of the present utility model includes: a bottom plate 1, which is used as the basic support structure of the entire fixture. The lower surface of the bottom plate 1 is fixedly connected with a motor 12, which is used to provide a power source. By driving the lead screw 6 to rotate, the placement plate 9 and the workpiece thereon are driven to perform a lifting movement. The output end of the motor 12 is fixedly connected with a lead screw 6, which is used to convert the rotational movement of the motor 12 into a linear movement. The side surface of the lead screw 6 is movably connected with a placement plate 9, which is used to place and support the sealing surface of the engine hood cover to be processed. The lead screw 6 penetrates through the bottom plate 1 and the placement plate 9 and is located behind the placement plate 9. The upper surface of the placement plate 9 is fixedly connected with a protective shell 4, which is used to protect the hydraulic rod 8. The protective shell 4 is located on the left and right sides of the placement plate 9. The protective shell 4 is provided with an outlet for the hydraulic rod 8 to extend. The inner wall of the protective shell 4 far from the outlet is fixedly connected with a hydraulic rod 8, which is used to drive the clamping plate 10 to move. The end of the hydraulic rod 8 far from the inner wall is fixedly connected with a clamping plate 10, which is used to clamp and fix the sealing surface of the engine hood cover placed on the placement plate 9. The clamping plate 10 covers the outlet.
[0024] The upper surface of the bottom plate 1 is fixedly connected with a support plate 2 for installing the telescopic plate 7. The opposite surfaces of the support plate 2 are fixedly connected with the telescopic plate 7 for limiting the position after the workpiece rises. The protective shell 4 is located directly below the telescopic plate 7. The placement plate 9 is located above the bottom plate 1. The upper surface of the bottom plate 1 is fixedly connected with a support frame 5 for ensuring the stability and precision of the lead screw 6 during rotation. The support frame 5 is located behind the support plate 2. The upper top wall of the support frame 5 is provided with a positioning hole for positioning the lead screw 6. One end of the lead screw 6 away from the motor 12 is located inside the positioning hole to prevent the lead screw 6 from shifting. The upper surface of the bottom plate 1 is fixedly connected with a baffle 11 for preventing the placement plate 9 from shifting. The baffle 11 is located behind the placement plate 9 and directly below the support frame 5. The lower surface of the bottom plate 1 is fixedly connected with a support column 3 for supporting the bottom plate 1. The lower end of the support column 3 is fixedly connected with an anti-slip pad for ensuring the stable placement of the fixture.
[0025] Working principle: First, place the sealing surface of the engine hood on the placement plate 9 and ensure that it is located between the protective shells 4. Subsequently, start the hydraulic rod 8. The hydraulic rod 8 pushes the clamping plate 10 towards both end faces of the sealing surface of the engine hood until the clamping plate closely adheres to and clamps the workpiece, ensuring that the engine hood does not move or shake during processing. After the workpiece is stably clamped, start the motor 12. The motor 12 drives the lead screw 6 to rotate. Through the connection between the lead screw 6 and the placement plate 9, the rotational motion is converted into a linear motion, thereby driving the placement plate 9 and the sealing surface of the engine hood thereon to move upward. During the upward movement of the placement plate 9, the telescopic plate 7 will correspondingly extend. The telescopic plate 7 enables the fixture to be flexibly adjusted according to engine hoods of different heights. When the placement plate 9 drives the sealing surface of the engine hood to rise, the telescopic plate will limit its height to ensure that the workpiece maintains a stable posture and position during processing, enhancing the adaptability and flexibility of the fixture and enabling it to handle workpieces of different specifications. When the clamping plate 10 clamps a higher workpiece, it avoids the unstable phenomenon that occurs when the clamping plate 10 solely clamps the bottom of the workpiece.
[0026] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art to which it pertains, various changes can also be made without departing from the gist of the present invention.
