[0002] In the machining process, parts often need to be clamped and fixed to facilitate the machining operation. However, for thin-walled bracket parts such as U-shaped thin-walled brackets, the following phenomena may occur when clamping them: excessive clamping force can easily cause deformation of thin-walled bracket parts such as U-shaped thin-walled brackets, affecting the machining quality of the parts; insufficient clamping may cause thin-walled bracket parts such as U-shaped thin-walled brackets to separate from the clamping mechanism, affecting the normal machining of the parts.

[0032] See Figure 1 and Figure 2As shown, the external clamping structure 5 is connected to the base 1. The external clamping structure 5 includes a second bidirectional lead screw 55 symmetrically arranged front and rear, a guide rod 57, and two U-shaped external clamping plates 56 symmetrically arranged left and right. Specifically, the second bidirectional lead screw 55 is located in the middle of the front end side groove 3.

Furthermore, a second bearing 54 is provided at the connection between the second bidirectional lead screw 55 and the base 1. The second bearing 54 is a sealed bearing. The above design can reduce the friction and wear on the second bidirectional lead screw 55.

[0033] In one embodiment of this utility model, the clamping and fixing device for processing thin-walled bracket-type parts using the above-described structure initially places the U-shaped thin-walled bracket 7 upside down on two inner support plates 48, so that the inner support plates 48 are both located inside the U-shaped thin-walled bracket 7. The controller 6 controls the first servo motor 41 to work, which can drive the first bidirectional lead screw 44 to rotate under the action of the first coupling 43. As the first bidirectional lead screw 44 rotates, due to the cooperation between the slider 45 and the center groove 2, the slider 45 will move along the axial direction of the first bidirectional lead screw 44. The two ends of the first bidirectional lead screw 44 are threaded together, and the two sliders 45 will move closer or further away. When the two sliders 45 move away, they will contact the two inner side walls of the U-shaped thin-walled bracket 7 respectively. Then, the controller 6 controls the operation, which can drive the electric telescopic rod 47 to extend and retract. The extension of the electric telescopic rod 47 can drive the inner support plate 48 to move upward. The U-shaped thin-walled bracket 7 on the inner support plate 48 moves upward and moves upward. When the upper end face of the U-shaped thin-walled bracket 7 is flush with the upper end face of the U-shaped outer clamping plate 56, the initial position adjustment and clamping operation of the U-shaped thin-walled bracket 7 can be realized.
[0034] Then, the controller 6 controls the second servo motor 51 to work, which, under the action of the second coupling 53, drives the second bidirectional lead screw 55 to rotate. As the second bidirectional lead screw 55 rotates, due to the cooperation of the U-shaped outer clamp 56 and the guide rod 57, the U-shaped outer clamp 56 will move along the central axis of the second bidirectional lead screw 55. Since the two U-shaped outer clamps 56 are connected to both ends of the second bidirectional lead screw 55 respectively, the two U-shaped outer clamps 56 will also move closer or further apart. When the two U-shaped outer clamps 56 approach each other, they will gradually contact the two outer surfaces of the U-shaped thin-walled bracket 7. With the cooperation of the adjacent inner support plate 48, the clamping and fixing operation of the two vertical plates of the U-shaped thin-walled bracket 7 can be achieved. Once the U-shaped thin-walled bracket 7 is clamped and fixed as per the attached instruction manual... Figure 4 As shown, subsequent machining operations on the U-shaped thin-walled support 7 can be realized.
[0035] It is worth noting that the controller 6 uses existing technology to control the operation of the first servo motor 41, the electric telescopic rod 47, and the second servo motor 51.
[0036] The preferred connection method in this invention is screw connection.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
