Specific embodiments

[0022] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] As Figures 1-5 shown, a special-shaped metal processing fixture includes a base 1, a chuck 2 and a swing frame 3. A plurality of slideways 4 are opened on the inner side of the base 1. The inner walls of the plurality of slideways 4 are all slidably connected with slide seats 5. The plurality of slideways 4 are four, and the four slideways 4 are respectively located in four directions. The slideways 4 can maintain the stability of the slide seat 5 when it is stressed, so that the slide seat 5 will not move its position when it is stressed. By supporting the slide seat 5 left and right through the slideways 4, guide rails 8 are connected to the inner walls of the plurality of slideways 4, and the outer surfaces of the guide rails 8 are all slidably connected with the inner walls of the slide seats 5. By slidably supporting the slide seat 5 through the guide rails 8, the stability of the slide seat 5 is further improved.

[0024] The inner wall of the slide seat 5 is fixedly rotatably connected to the outer surface of the swing frame 3. The swing frame 3 has a rotating function, and the angle of the swing frame 3 is changed by rotation. The inner wall of the swing frame 3 is fixedly rotatably connected to the outer surface of the chuck 2. The chuck 2 is supported by the rotation of the swing frame 3, and the angle of the chuck 2 is changed by rotation. The inner side of the slide seat 5 is threadedly connected with a lead screw 6, and the outer surface of the lead screw 6 is rotatably connected to the inner side of the base 1. The rotation of the lead screw 6 provides power for the slide seat 5 to move its position.

[0025] A positioning mechanism 7 is provided outside the lead screw 6. The stability of the lead screw 6 is maintained through the positioning mechanism 7. The positioning mechanism 7 includes a barrel seat 701. One side of the barrel seat 701 is connected to the outer surface of the base 1. A sliding cylinder 702 is slidably connected to the inner wall of the barrel seat 701. A spring 703 is connected to the inner bottom wall of the barrel seat 701, and the other end of the spring 703 is connected to the inner top wall of the sliding cylinder 702. The sliding seat 5 enables the sliding cylinder 702 to have a sliding function. After the sliding cylinder 702 is pushed externally and slides into the barrel seat 701, the spring 703 is compressed. After the external driving force on the sliding cylinder 702 is lost, the spring 703 pushes the sliding cylinder 702 to slide out of the barrel seat 701. A positioning pin 704 is connected to the outer surface of the sliding cylinder 702, and a positioning groove 705 is formed on the inner side of the barrel seat 701. The positioning pin 704 is slidably connected to the positioning groove 705. The positioning groove 705 enables the positioning pin 704 to only have a sliding function. The rotation of the sliding cylinder 702 can be restricted through the positioning groove 705 and the positioning pin 704. If the sliding cylinder 702 rotates, the positioning and support for the lead screw 6 will be lost. When the sliding cylinder 702 slides into the barrel seat 701, it drives the positioning pin 704 to slide inside the positioning groove 705. Due to the block of the positioning pin 704, the sliding cylinder 702 only has a sliding function and cannot rotate. One end of the sliding cylinder 702 located outside the barrel seat 701 is connected to a first gear disk 706, and a second gear disk 707 is connected to the outer surface of the lead screw 6. The first gear disk 706 is in sliding contact with the second gear disk 707. Through the misaligned contact between the first gear disk 706 and the second gear disk 707, when no external force is applied to the lead screw 6, the stability of the lead screw 6 is maintained through the support of the first gear disk 706 for the second gear disk 707, and the lead screw 6 cannot rotate.

[0026] One end of the lead screw 6 located outside the base 1 is slidably connected to a force - adding rod 9. Four mounting seats 10 are connected to the outer surface of the sliding seat 5, and the four mounting seats are respectively located at the four corners of the base 1. Through the mounting seats 10, the base 1 can be mounted on the processing equipment and the stability of the base 1 can be maintained. A workbench 11 is connected to the upper surface of the base 1, and the workbench 11 is located at the central position of the base 1. The special - shaped metal part is supported by the workbench 11.

[0027] It should be noted that during the actual use of the device, first place the special-shaped part on the workbench 11. Rotate the lead screw 6 to push the sliding seat 5 to move. While the sliding seat 5 is moving, it drives the swing frame 3 and the chuck 2 to move simultaneously. Subsequently, the chuck 2 contacts the special-shaped metal part. When the chuck 2 contacts the special-shaped metal part, the chuck 2 will change its angle according to the shape of the special-shaped metal part, and at the same time, the swing frame 3 also rotates to adapt to the appearance requirements of the special-shaped metal part. While the lead screw 6 is rotating, it drives the second gear disk 707 to rotate. The second gear disk 707 pushes the first gear disk 706 to move backward. The first gear disk 706 pushes the sliding cylinder 702 to slide into the barrel seat 701. At the same time, the sliding cylinder 702 compresses the spring 703. After the lead screw 6 stops rotating, the first gear disk 706 loses the push of the second gear disk 707. Subsequently, the spring 703 pushes the sliding cylinder 702 and the first gear disk 706 to slide out of the barrel seat 701. Subsequently, the first gear disk 706 contacts the second gear disk 707.
