Specific embodiments

[0026] In order to make the objectives, 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.

[0027] Please refer to Figures 1-4 , the present utility model provides a fixing structure for thin - wall part processing, including a base plate 1 which increases the contact surface at the bottom end, making the stability better. A control panel 17 is installed outside the base plate 1 to make it more convenient for users to operate. A number of fixed chutes 2 are provided inside the base plate 1. The fixed chutes 2 can be equidistantly arranged inside the base plate 1, making the thin - wall part more stable when being fixed later. Lead screws 3 are connected inside the fixed chutes 2 through bearings, and the threads of the lead screws 3 are symmetrically arranged in positive and negative directions, so that when the lead screws 3 rotate, the fixed sliders 6 can be moved inward or outward simultaneously, facilitating the clamping of the thin - wall part. A moving slot 5 running upward is provided at the upper end of the fixed chute 2, so that the fixed chute 2 can limit the fixed slider 6 and avoid the problem of being pulled out upward. Fixed sliders 6 are symmetrically arranged inside the fixed chutes 2, and threaded holes are provided inside the fixed sliders 6 to connect with the lead screws 3. A motor 4 is installed outside the base plate 1, and the output end of the motor 4 is connected to the lead screw 3. When the motor 4 drives the lead screw 3 to rotate, the fixed slider 6 moves, thereby driving the side fixing plate 7 to move to clamp the thin - wall part, thus realizing the driving effect and avoiding the inconvenience of manual rotation.

[0028] The fixed slider 6 is provided with a side fixing plate 7 passing through the moving slot 5, and different sizes are formed between the moving slot 5 and the fixed chute 2 to limit the upper end of the fixed slider 6. The inner wall of the side fixing plate 7 is provided with a side pressure sensor 16, so that when the side fixing plate 7 clamps the thin-walled part inward, the situation of excessive inward clamping force can be avoided under the action of the side pressure sensor 16. The bottom end of the pressing plate 10 is provided with a top pressure sensor 11, and under the action of the top pressure sensor 11, the downward pressing force is controlled to avoid the deformation of the thin-walled part caused by excessive pressure. The bottom end face of the top pressure sensor 11 is covered and connected with a force-bearing plate 12, and the force-bearing plate 12 is made of rubber material, so that the force-bearing plate 12 can increase the friction force on the thin-walled part and increase flexibility to reduce damage. The inside of the side fixing plate 7 is provided with an up-and-down chute 8 penetrating left and right, and a pressing plate 10 spanning both sides is installed inside the up-and-down chute 8, so that the pressing plate 10 moves up and down inside the up-and-down chute 8 to press thin-walled parts of different heights. The top of the side fixing plate 7 is installed with an electric push rod 9, and the output end of the electric push rod 9 penetrates the moving slot 5 and is slidably connected with the pressing plate 10. Under the action of the electric push rod 9, the pressing plate 10 is pushed up and down to press the thin-walled part, avoiding manual pushing and making the work efficiency higher. The output end of the electric push rod 9 is connected with a pushing slider 15. The upper end of the pressing plate 10 is provided with a force-bearing chute 13, and the upper end of the force-bearing chute 13 is provided with a penetrating upper slot 14 slidably connected with the output end of the electric push rod 9, and the pushing slider 15 is slidably connected with the force-bearing chute 13, so that when the side fixing plate 7 moves, the pushing slider 15 and the force-bearing chute 13 slide to avoid applying a lateral thrust to the pressing plate 10, and the pressing plate 10 can only move up and down for pressing work.

[0029] Preferably, the length dimension of the pressing plate 10 is the same as the length dimension of the fixed chute 2, so that thin-walled parts of the same size and width can be pressed, making the stability better. The bottom end of the fixed chute 2 is provided with an opening penetrating the base plate 1, so as to avoid the situation that the debris generated during the processing of the thin-walled part enters the inside of the fixed chute 2 and is not easy to discharge.

[0030] Working principle: When in use, first connect the motor 4, the electric push rod 9, the top pressure sensor 11, the side pressure sensor 16 and the control panel 17 to an external power supply, then place the thin-walled part between the side fixing plates 7 on the base plate 1, and then the motor 4 drives the lead screw 3 to rotate, so that the lead screw 3 drives the fixed slider 6 to move towards each other, making the side fixing plate 7 clamp the side of the thin-walled part, and the side pressure sensor 16 can avoid excessive force during the clamping process. Then the electric push rod 9 pushes the pushing slider 15 downward to make the pressing plate 10 press the thin-walled part downward to complete the fixing work of the thin-walled part.

[0031] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments, and the above embodiments and the descriptions in the specification are only preferred examples of the present utility model, and are not used to limit the present utility model.
