It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0021] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0022] Embodiment 1, as Figures 1-5 shown, the present utility model provides a numerically controlled expanding machine, including: a base 1, a mounting plate 18 is fixedly connected to the top of the base 1 near the right side, a linear motor 17 is fixedly connected to the inner surface of the base 1 near the right side, the output end of the linear motor 17 is fixedly connected to a lead screw 15, a slide seat 7 is threadedly connected to the outer surface of the lead screw 15, support frames 6 are fixedly connected to the tops of both the slide seat 7 and the mounting plate 18, driving motors 2 are fixedly connected to the tops of the two support frames 6, threaded rods 3 are fixedly connected to the output ends of the two driving motors 2, slide tables 4 are threadedly connected to the outer surfaces of the two threaded rods 3, first lifting mechanisms 5 are fixedly connected to the tops of the two slide tables 4, side claw mechanisms 11 are sleeved on the outer surfaces of the two first lifting mechanisms 5, driving mechanisms 16 are symmetrically arranged on the adjacent sides of the two support frames 6, flipping assemblies 10 are fixedly connected to the tops of multiple driving mechanisms 16, the multiple flipping assemblies 10 are divided into two groups, front claw mechanisms 12 are fixedly connected to the tops of one group of flipping assemblies 10, second lifting mechanisms 8 are fixedly connected to the tops of the other group of flipping assemblies 10, rear claw mechanisms 9 are arranged on the outer surfaces of the two second lifting mechanisms 8, the outer surfaces of the two slide tables 4 are respectively matched with the outer surfaces of the two support frames 6, the outer surface of the slide seat 7 is matched with the outer surface of the base 1, and the two front claw mechanisms 12 are respectively matched with the positions of the two rear claw mechanisms 9.

[0023] The effect achieved by the entire Embodiment 1 is that the first lifting mechanism 5 uses a stepping motor to drive the driving rod to rotate, causing the moving seat to move up and down, and the sliding seat to move back and forth through the electric telescopic rod. The second lifting mechanism 8 uses a slide rail, a sliding seat, and a driving device and is connected by screw drive. The driving mechanism 16 also uses a slide rail, a sliding seat, and a driving device and is connected by screw drive. When bulging the workpiece, by starting the linear motor 17, the lead screw 15 is driven to rotate in the base 1, causing the sliding seat 7 to move horizontally along the base 1, so as to adjust the positions of the two support frames 6 according to the position of the workpiece. Then, the driving mechanism 16 is started to drive one set of flipping components 10 to move, and the distance between the front claw mechanism 12 and the rear claw mechanism 9 can be adjusted. At the same time, the angles of the front claw mechanism 12 and the rear claw mechanism 9 can be adjusted through the flipping components 10, making it more convenient to fix the workpiece. At the same time, through the second lifting mechanism 8, the height of the rear claw mechanism 9 can be adjusted, enabling the rear claw mechanism 9 to adapt to more different-shaped workpieces. When the front and rear sides of the workpiece are fixed by the front claw mechanism 12 and the rear claw mechanism 9, by starting the driving motor 2, the threaded rod 3 is driven to rotate, causing the slide table 4 to move horizontally along the outside of the support frame 6, driving the first lifting mechanism 5 to move to the side of the workpiece, and then the horizontal position and height of the side claw mechanism 11 are further adjusted through the first lifting mechanism 5, enabling the side claw mechanism 11 to fix the two sides of the workpiece. It can conveniently adjust the positions of the front claw mechanism 12, the rear claw mechanism 9, and the side claw mechanism 11, adapt to workpieces of different sizes and shapes, and increase the usage range and flexibility of the equipment.

[0024] Embodiment 2, as Figures 1-5 shown, the bottoms of the two support frames 6 are fixedly connected with electric push rods 13, and the driving ends of the two electric push rods 13 both penetrate through the bottoms of the support frames 6 movably. The driving ends of the two electric push rods 13 are fixedly connected with top arcs 14.

[0025] The effect achieved by the entire Embodiment 2 is that when the workpiece is fixed by the front claw mechanism 12, the rear claw mechanism 9, and the side claw mechanism 11, the electric push rod 13 can be started to drive the top arc 14 to move up and down, thereby supporting the workpiece through the top arc 14, ensuring that the workpiece is evenly stressed and stable during processing, preventing the workpiece from deforming due to uneven stress, and thus improving the processing accuracy and quality.

[0026] Working principle: When bulging the workpiece, start the linear motor 17 to drive the lead screw 15 to rotate in the base 1, so that the sliding seat 7 moves horizontally along the base 1, thereby adjusting the positions of the two support frames 6 according to the position of the workpiece. Then start the driving mechanism 16 to drive one set of flipping components 10 to move, which can adjust the distance between the front claw mechanism 12 and the rear claw mechanism 9. At the same time, through the flipping components 10, the angles of the front claw mechanism 12 and the rear claw mechanism 9 can be adjusted to make it more convenient to fix the workpiece. At the same time, through the second lifting mechanism 8, the height of the rear claw mechanism 9 can be adjusted so that the rear claw mechanism 9 can adapt to more workpieces with different shapes. When the front and rear sides of the workpiece are fixed by the front claw mechanism 12 and the rear claw mechanism 9, start the driving motor 2 to drive the threaded rod 3 to rotate, so that the sliding table 4 moves horizontally along the outside of the support frame 6, driving the first lifting mechanism 5 to move to the side of the workpiece. Then, through the first lifting mechanism 5, the horizontal position and height of the side claw mechanism 11 are further adjusted so that the side claw mechanism 11 can fix the two sides of the workpiece. At the same time, the electric push rod 13 can be started to drive the top arc 14 to move up and down, so as to support the workpiece through the top arc 14, ensure that the workpiece is evenly stressed and stable during processing, prevent the workpiece from deforming due to uneven stress, and thus improve the processing accuracy and quality.

[0027] The wiring diagrams of the driving motor 2, the first lifting mechanism 5, the second lifting mechanism 8, the rear claw mechanism 9, the side claw mechanism 11, the front claw mechanism 12, the electric push rod 13, the driving mechanism 16 and the linear motor 17 in the present utility model belong to the common knowledge in the art. Their working principles are already known technologies, and their models are selected according to actual use. Therefore, the control methods and wiring arrangements of the driving motor 2, the first lifting mechanism 5, the second lifting mechanism 8, the rear claw mechanism 9, the side claw mechanism 11, the front claw mechanism 12, the electric push rod 13, the driving mechanism 16 and the linear motor 17 will not be explained in detail.

[0028] The above is only a preferred embodiment of the present utility model, and it does not limit the present utility model in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields.
