[0002] Plastic products refer to articles made mainly of plastics through various processing techniques, and plastic pipes are tubular products made of plastic materials. During the processing of some plastic pipes, punching operations need to be performed on their surfaces;

[0003] When performing punching operations on longer plastic pipes, one end of the plastic pipe is positioned below the punch, while the other side of the plastic pipe is suspended outside the processing area. During the processing, manual support is required. When manually supporting, punching may be inclined. Moreover, when it is necessary to perform punching on multiple surfaces of the plastic pipe, manually rotating to drive the plastic pipe to rotate may cause the position of the plastic pipe to deviate, resulting in inaccurate hole positions, and the overall punching effect needs to be improved.

[0022] A workpiece support structure for a plastic product processing lathe, as Figure 1 - Figure 4As shown in the figure, it includes a frame 1, on which a stamping head 2 is movably installed. A support frame 3 is fixedly installed on the frame 1. The support frame 3 is fixedly installed on the frame 1 through fasteners. When punching different types of plastic pipes, the support frame 3 can be replaced. Two mounting frames 8 are movably installed on the frame 1. The two mounting frames 8 are movably installed on the frame 1 through an adjustment component. The adjustment component can flexibly adjust the position and height of the mounting frame 8 according to the model of different plastic pipes during the punching process to keep the two ends of the plastic pipe on the same horizontal line and ensure the position of the mounting frame 8 is adjusted according to the length of the plastic pipe. A support and rotation component is arranged between the two mounting frames 8. The clamping and rotation component can ensure the accurate punching position of the plastic pipe when rotating and punching multiple surfaces of the plastic pipe; by setting an adjustment component, when punching a longer plastic pipe, one end of the plastic pipe is positioned on the support frame 3, the stamping head 2 punches the plastic pipe, and the support and rotation component on the other side can support the other end of the plastic pipe and adjust it through the adjustment component to ensure that the two ends of the plastic pipe are on the same horizontal line. When rotating and punching multiple surfaces of the plastic pipe is required during the punching process, the support and rotation component can be used to drive the plastic pipe to rotate stably to ensure the accuracy of the hole position after punching.

[0023] Furthermore, the adjustment component includes a cross plate 5. The two cross plates 5 are arranged on both sides of the top of the frame 1. On one side of the cross plate 5, a mounting seat 4 is fixedly installed. The mounting seat 4 is fixedly installed on the frame 1 through fasteners. A vertical plate 6 is slidably installed on the cross plate 5. A connecting frame 7 is slidably installed on the vertical plate 6. The connecting frame 7 can be connected and fixed to the vertical plate 6 through fasteners. The connecting frame 7 is fixedly connected to the corresponding mounting frame 8; by setting an adjustment component, when supporting and rotating the plastic pipe, one end of the plastic pipe is positioned on the support frame 3, and the other end of the plastic pipe is supported by the support and rotation component. During support, the position of the connecting frame 7 is adjusted to ensure that the two ends of the plastic pipe are in a horizontal state to ensure the punching effect. During the punching process, by sliding the vertical plate 6 to drive the plastic pipe to extend towards the punching area side, it can ensure that the plastic pipe moves stably on the horizontal line during punching to ensure the punching effect.

[0024] Further, the support rotating assembly includes a first ring gear plate 9 which is rotatably installed on the mounting bracket 8 on one side. A second ring gear plate 10 is rotatably installed on the mounting bracket 8 on the other side. A first driving gear 11 is rotatably installed on the mounting bracket 8 on one side. The first driving gear 11 meshes with the first ring gear plate 9. A second driving gear 12 is rotatably installed on the mounting bracket 8 on the other side. The second driving gear 12 meshes with the second ring gear plate 10. The first driving gear 11 and the synchronous pulley 13 are driven to rotate synchronously through a synchronous driving assembly. Two fixing seats 15 are slidably installed between the first ring gear plate 9 and the second ring gear plate 10. A positioning fixture 16 is fixedly installed on the fixing seat 15. The positioning fixture 16 is fixedly connected to the fixing seat 15 through a fastener. When punching plastic pipes of different models, different positioning fixtures 16 can be replaced according to the model of the plastic pipe. Four springs 17 are fixedly installed between the two fixing seats 15. Both ends of the spring 17 are fixedly connected to the two fixing seats 15 respectively. By providing the support rotating assembly, when punching a plastic pipe, one end of the plastic pipe is positioned on the support frame 3, the position of the mounting bracket 8 is adjusted, the other end of the plastic pipe is passed through between the two positioning fixtures 16, and the elastic force of the spring 17 is used to clamp and fix one end of the plastic pipe by the positioning fixtures 16 on both sides. By adjusting the position of the mounting bracket 8, it is ensured that both ends of the plastic pipe are on the same horizontal line. When punching, the punching head 2 can perform a punching operation on the plastic pipe. When punching, the plastic pipe can be moved horizontally for punching by sliding the vertical plate 6. If multi-sided punching of the plastic pipe is required, the first driving gear 11 and the second driving gear 12 can be driven to rotate and mesh with the first ring gear plate 9 and the second ring gear plate 10 respectively to drive the plastic pipe to rotate and switch the punching angle in the same plane, so as to improve the overall punching effect.

[0025] Further, the synchronous driving assembly includes the synchronous pulley 13. Four synchronous pulleys 13 are rotatably installed on the two mounting brackets 8. Two of the synchronous pulleys 13 are fixedly connected to the corresponding first driving gear 11 and second driving gear 12 respectively. A synchronous belt 14 is arranged between the four synchronous pulleys 13. The synchronous belt 14 is movably connected to the four synchronous pulleys 13. One of the synchronous pulleys 13 is driven by a servo motor. The servo motor is electrically connected to an external controller. By providing the synchronous driving assembly, when rotating and switching the angle of the plastic pipe, the servo motor can be controlled to drive one of the synchronous pulleys 13 to rotate, and the synchronous belt 14 is used to drive the other three synchronous pulleys 13 to rotate synchronously, so as to drive the first driving gear 11 and the second driving gear 12 to rotate synchronously and mesh with the first ring gear plate 9 and the second ring gear plate 10 respectively to drive the plastic pipe to rotate and switch the punching angle.

[0026] Working principle of the utility model: The other end of the plastic pipe is passed through between two positioning jigs 16, and the elastic force of the spring 17 is used to clamp and fix one end of the plastic pipe by the positioning jigs 16 on both sides. The position of the mounting bracket 8 is adjusted to ensure that both ends of the plastic pipe are on the same horizontal line. During punching, the punching head 2 can perform punching operations on the plastic pipe. When punching, the vertical plate 6 can be slid to ensure that the plastic pipe moves horizontally for punching. If multi-sided punching of the plastic pipe is required, the servo motor can be controlled to drive one of the synchronous pulleys 13 to rotate, and the synchronous belt 14 is used to drive the other three synchronous pulleys 13 to rotate synchronously, so as to drive the first driving gear 11 and the second driving gear 12 to rotate synchronously and mesh with the first ring gear plate 9 and the second ring gear plate 10 respectively to drive the positioning jig 16 to rotate, thereby driving the plastic pipe to rotate and switch the punching angle on the same plane.
