[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figures 1-3 The present invention provides an embodiment of a symmetrical dual-spindle CNC lathe, comprising a CNC lathe body 1, a spindle body 2 disposed inside the CNC lathe body 1, which clamps the automobile axle; a servo motor 3 fixedly connected to the inner wall of the CNC lathe body 1; a threaded rod 4 fixedly connected to the output end of the servo motor 3; the operation of the servo motor 3 drives the threaded rod 4 to rotate inside the CNC lathe body 1; a moving block 5 is threadedly connected to the outer surface of the threaded rod 4; the moving block 5 is slidably connected to the inner wall of the CNC lathe body 1; a threaded sleeve is disposed inside the moving block 5; the rotation of the threaded rod 4 drives the threaded sleeve and the moving block 5 to move. Furthermore, a positioning mechanism 6 is provided on the side wall of the movable block 5, and a push block 7 is fixedly connected to the bottom of the movable block 5. The movement of the movable block 5 drives the push block 7 to slide. A cleaning component 8 is provided inside the CNC lathe body 1. A connecting block 9 is inserted into the side wall of the movable block 5. A connecting groove is opened on the side wall of the movable block 5. The size of the connecting block 9 is adapted to the size of the connecting groove. The connecting groove allows the connecting block 9 to be stably inserted into the inside of the movable block 5. A milling cutter 10 is provided on the side wall of the connecting block 9. The movement of the connecting block 9 drives the milling cutter 10 to move. A placement base 11 is provided on the side wall of the CNC lathe body 1. A placement groove is opened inside the placement base 11 to place the car axle. A collection frame 12 is snapped into the bottom of the CNC lathe body 1. The collection frame 12 collects and cleans waste chips.

[0019] Reference Figures 3-4 The positioning mechanism 6 includes a positioning plate 61, the side wall of which is hinged to the side wall of the moving block 5. A push plate is fixedly connected to the bottom of the positioning plate 61. By pushing the push plate, one side of the moving block 5 is lowered. A positioning block 63 is fixedly connected to the side wall of the positioning plate 61. A positioning groove is provided on the side wall of the connecting block 9. The positioning block 63 passes through the moving block 5 and is inserted into the positioning groove. The descent of one side of the positioning plate 61 drives the other side and the positioning block 63 to slide, so that the positioning block 63 is stably inserted into the positioning groove, improving the stable connection between the connecting block 9 and the moving block 5. The side wall of the positioning block 63 is elastically connected to the side wall of the moving block 5 through a positioning spring 62. Pressing the push plate squeezes the positioning spring 62, causing the positioning spring 62 to deform. When resetting, the rebound of the positioning spring 62 drives the push plate and the positioning plate 61 to slide and reset.

[0020] Reference Figures 3-5 The cleaning component 8 includes a cleaning airbag 81, which is fixedly connected inside the CNC lathe body 1. The CNC lathe body 1 has a placement slot for holding the cleaning airbag 81. A protrusion 82 is fixedly connected to the top of the cleaning airbag 81. The bottom of a pusher block 7 contacts the top of the protrusion 82. During sliding, the pusher block 7 pushes the top of the protrusion 82, causing the protrusion 82 to press against the cleaning airbag 81. A connecting pipe 83 connects to the side wall of the protrusion 82. The bottom of the tube 83 is connected to a cleaning tube 84. The side wall of the cleaning tube 84 is fixedly connected to the inner side wall of the CNC lathe body 1. The gas inside the cleaning airbag 81 is transported to the inside of the cleaning tube 84 through the connecting tube 83. The side wall of the cleaning tube 84 is connected to a cleaning nozzle 85. There are multiple cleaning nozzles 85, which are evenly distributed on the side wall of the cleaning tube 84. After the gas is discharged by the cleaning nozzles 85, it can clean the waste generated during the working process and improve the cleanliness of the CNC lathe body 1 during the working process.

[0021] Working principle: During use, the car axle to be processed is placed on top of the base 11. Then, the main shaft body 2 stabilizes and fixes both sides of the car axle. After the car axle is fixed, the servo motor 3 drives the threaded rod 4 to rotate. The rotation of the threaded rod 4 drives the moving block 5 to move, which in turn drives the connecting block 9 and the milling cutter 10 to move. The milling cutter 10 is used to process the car axle. When waste is generated during the processing of the car axle, the movement of the moving block 5 drives the push block 7 to move. The movement of the push block 7 pushes the protrusion 82. When the protrusion 82 is pushed, it squeezes the cleaning airbag 81, causing the cleaning airbag 81 to deform. The gas inside is transported from the inside of the connecting pipe 83 to the inside of the cleaning pipe 84 and discharged through the cleaning nozzle 85, which satisfies the cleaning effect of the waste generated during the process. The cleaned waste enters the inside of the collection frame 12, which satisfies the effect of collecting the waste. When the milling cutter 10 needs to be disassembled and replaced after long-term use, pressing the push plate at the bottom of the positioning plate 61 squeezes the positioning spring 62, causing the end of the positioning plate 61 to tilt up, causing the positioning block 63 to be pulled out from the side wall of the connecting block 9 and the moving block 5. Then, the connecting block 9 is pulled out from the inside of the moving block 5, which satisfies the effect of disassembling and replacing the milling cutter 10. After the milling cutter 10 is replaced, the connecting block 9 is inserted into the inside of the moving block 5. At the same time, after releasing the push plate, the rebound of the positioning spring 62 causes the positioning plate 61 to slide and reset, causing the positioning block 63 to be inserted into the inside of the moving block 5 and the connecting block 9, improving the stability of the milling cutter 10 during the connection process.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
