[0028] like Figure 1-2 As shown, a CNC lathe for processing plastic parts comprises a workbench 1 and a fixture 2. The top of the workbench 1 is fixedly connected to the fixture 2. A cylinder 3 is arranged at the front of the fixture 2. The end of the cylinder 3 close to the fixture 2 is rotatably connected to a telescopic rod 4. The telescopic rod 4 is inserted on the fixture 2. The end of the telescopic rod 4 away from the cylinder 3 is rotatably connected to a push plate 5. The top of the fixture 2 is fixedly connected to a support box 6. A cylinder 7 is arranged on the top of the support box 6. The bottom of the cylinder 7 is fixedly connected to a telescopic rod 17. The telescopic rod 17 on the cylinder 7 is inserted in the support box 6. The telescopic rod 17 away from the cylinder 3 is rotatably connected to the push plate 5. One end of the cylinder 2 7 is fixedly connected to a connecting block 16, and the interior of the connecting block 16 is rotatably connected to a bearing 14, and a rotating shaft 13 is arranged inside the bearing 14. A guide roller 15 is arranged on the side of the rotating shaft 13 close to the bearing 14. There are two guide rollers 15, and a motor 8 is arranged on the end of the rotating shaft 13 close to the cylinder 1 3. By setting a clamp 2 and setting a guide roller 15 on the rotating shaft 13, the cylinder 2 7 is started, and the telescopic rod 2 17 drives the connecting block 16 and the guide roller 15 to move downward, so that the guide roller 15 and the clamp 2 can press workpieces of different sizes, so that the CNC lathe can adapt to workpieces of different specifications, thereby improving the practicality of the CNC lathe.

[0029] Embodiment 2

[0030] like Figure 3-4As shown, an inner groove 1 is opened in the middle of the workbench 1, and a sewage tank 11 is arranged on the side of the bottom of the workbench 1 close to the inner groove 1. The top of the sewage tank 11 is fixedly connected with limiting columns on all sides. The number of the limiting columns is four, and the limiting columns are fixedly inserted in the bottom of the waste box 9. A filter screen 10 is installed on the inner side of the waste box 9. An L-shaped baffle 18 is fixedly connected to the bottom of the workbench 1 close to the side of the waste box 9. By arranging the filter screen 10 inside the waste box 9, the waste generated when cutting the workpiece can be filtered, and the waste liquid can be separated from the waste, thereby facilitating the subsequent treatment of the waste and waste liquid.

[0031] A robotic arm 12 is fixedly connected to the top of the workbench 1 on the side away from the fixture 2, and a cutter body is fixedly connected to the end of the robotic arm 12 close to the fixture 2. A nozzle is provided on the top of the robotic arm 12 close to the cutter body. By installing the nozzle on the robotic arm 12, cutting fluid can be sprayed in time when cutting the workpiece.

[0032] The support box 6 is provided with an inner groove 2 on one side close to the motor 8, and the width of the inner groove 2 is greater than the width of the rotating shaft 13. The support box 6 is provided with a bracket 19 on one side close to the motor 8, and the bracket 19 is fixedly connected to the motor 8. The bracket 19 is fixedly connected with a slider on one side close to the support box 6. The support box 6 is provided with a slide groove on one side close to the slider, and the slider is engaged with the slide groove. The number of the sliders is the same as the number of the slide grooves, and the number of the slide grooves is two. By fixedly connecting the bracket 19 and the motor 8, and engaging the slider on the bracket 19 with the slide groove on the support box 6, the bracket 19 can support the motor 8 and prevent the rotating shaft 13 from bending due to the weight of the motor 8.

[0033] The height of the push plate 5 is smaller than that of the fixture 2. By providing a small push plate 5, the push plate 5 can be prevented from getting stuck in the bracket 19 when it is below the bracket 19, thereby preventing the bracket 19 and the guide roller 15 from being unable to smoothly press the workpiece.

[0034] The inner wall size of the sewage tank 11 is the same as the inner wall size of the waste box 9, and the inner wall size of the waste box 9 is the same as the inner wall size of the inner tank 1. The width of the inner tank 1 is greater than the width of the clamp 2. By providing an inner tank 1 that is wider than the clamp 2, waste and waste liquid are not easy to fall onto the surface of the workbench 1, thereby maintaining the cleanliness of the workbench 1.

[0035] Working principle: Figure 1-5As shown, first, place the workpiece inside the fixture 2, start the cylinder 13, the cylinder 13 pushes the telescopic rod 14, the telescopic rod 14 drives the push plate 5 and the workpiece to move to the specified position in the direction of the support box 6, and start the cylinder 27, the cylinder 27 pushes the telescopic rod 217, the telescopic rod 217 drives the connecting block 16, the guide roller 15 and the bracket 19 to move downward, so that the guide roller 15 presses the workpiece, so that the CNC lathe can adapt to workpieces of different sizes, and then start the motor 8, the motor 8 drives the rotating shaft 13 to rotate, and the rotating shaft 13 drives The guide roller 15 rotates with the workpiece, and then the nozzle on the robot arm 12 is connected to the external cutting fluid delivery pipe. By starting the robot arm 12, the robot arm 12 drives the cutter body and the nozzle to move. While the cutter body cuts the workpiece, the cutting fluid is sprayed on the workpiece through the nozzle. During the cutting process, the waste cut from the workpiece falls onto the filter screen 10 inside the waste box 9, and the cutting fluid sprayed from the nozzle falls into the sewage tank 11 through the filter screen 10, so that the cutting fluid is separated from the waste, thereby facilitating the subsequent processing of the cutting fluid and the waste separately.
