They are mainly used for cutting the inner and outer cylindrical surfaces, inner and outer conical surfaces with arbitrary cone angles, complex rotating inner and outer curved surfaces, and cylindrical and conical threads of shaft or disc parts. Existing CNC lathes generally lack a chip guide structure. The chips produced during machining usually fall directly onto the bed guide rails, and then fall into the chip collection tray through the through hole between the two guide rails. As a result, during the machining process, chips easily accumulate on the guide rails. When there is a lot of accumulation, it can affect the normal machining of the CNC lathe, thus requiring regular cleaning of chips, which increases the workload of the machining personnel.

[0014] 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.

[0015] Please see Figure 1-4 This embodiment provides a technical solution: a CNC lathe for machining, including a bed 1 and a striking unit 8; Bed 1: A large slide 2 is slidably connected to the middle of the bed, allowing mechanical parts to be mounted onto the chuck. The spindle motor inside the bed 1 rotates, driving the chuck and mechanical parts to rotate. The Z-axis motor on the bed 1 drives the large slide 2 to move laterally, while the X-axis motor on the large slide 2 drives the small slide, tool post, and cutting tool to move longitudinally, thus realizing CNC turning of the mechanical parts. A support shaft 3 is located at the rear end of the left side of the large slide 2, rotatably connected to the rear end of the chip conveyor 4. The support shaft 3 provides rotational support for the chip conveyor 4, and the waste chips generated during turning fall into the interior of the chip conveyor 4. The lower surface of the chip conveyor 4... Symmetrically distributed tension springs 5 ​​are provided between the front end of the chip conveyor 4 and the large slide 2. A support bar 6 is provided at the front end of the lower surface of the chip conveyor 4, and symmetrically distributed rubber columns 7 are provided at the front end of the upper surface of the large slide 2. The rubber columns 7 are configured to cooperate with the support bar 6. The chip conveyor 4 pulls the tension springs 5, and simultaneously, the chip conveyor 4 causes the support bar 6 to separate from the rubber columns 7. After the roller 83 separates from the support plate 9, the tension springs 5 ​​cause the chip conveyor 4 and support bar 6 to reset. The support bar 6 impacts the rubber columns 7. A chip collection disc 15 is movably inserted into the middle of the bed 1. The rear end of the chip conveyor 4 is located above the chip collection disc 15. The chip conveyor 4 vibrates when struck, and the chip conveyor 4 vibrates from the front... The lathe bed 1 is tilted downwards to allow waste chips to slide backwards into the chip collection tray 15. A lathe controller 17 is located at the upper end of the bed 1, and its input is electrically connected to an external power source. A chip baffle 10 is rotatably connected to the front end of the chip conveyor 4. The chip baffle 10 blocks flying waste chips to prevent injury. A rectangular strip 11 is slidably connected to the front end of the chip baffle 10, and its lower end is movably inserted into the front end of the chip conveyor 4. The rectangular strip 11 positions the chip baffle 10. Symmetrically distributed positioning blocks 14 are located at the front end of the chip conveyor 4, and both positioning blocks 14 are configured to cooperate with the chip baffle 10. The rotation range of the chip baffle 10 is limited. A positioning strip 12 is provided in the middle of the rectangular strip 11, and a spring plate 13 is provided in the middle of the chip baffle 10. The spring plate 13 and the positioning strip 12 are configured to cooperate with each other. The spring plate 13 and the positioning strip 12 limit the upward movement of the rectangular strip 11. When the rectangular strip 11 is pulled upward, the rectangular strip 11 drives the positioning strip 12 to move upward and squeeze the spring plate 13. The lower end of the rectangular strip 11 separates from the chip conveyor 4. The chip baffle 10 can be rotated and folded. The chip baffle 10 does not cover the processing position. A handle 16 is provided at the rear end of the chip collection tray 15. After use, the chip collection tray 15 can be pulled out backward by the handle 16 for cleaning. The striking unit 8 is used to drive the vibration of the chip conveyor 4. The striking unit 8 includes a motor 81, a rotating disk 82, and rollers 83. The motor 81 is located in the middle of the left side of the large slide plate 2. The output shaft of the motor 81 is equipped with a rotating disk 82. Rollers 83 are rotatably connected inside the two grooves on the outer arc surface of the rotating disk 82. Both rollers 83 are configured to cooperate with the chip conveyor 4. The input end of the motor 81 is electrically connected to the output end of the lathe controller 17. A support plate 9 is located in the middle of the lower surface of the chip conveyor 4. The support plate 9 is located above the rollers 83. When the motor 81 is running, the output shaft of the motor 81 drives the rollers 83 to rotate in a circle through the rotating disk 82. The rollers 83 will gradually contact the support plate 9 and strike it. The rollers 83 drive the chip conveyor 4 to rotate counterclockwise around the support shaft 3 through the support plate 9.

[0016] The working principle of the CNC lathe for machining provided by this utility model is as follows: During use, the mechanical parts are mounted on the chuck of the bed 1. The lathe controller 17 is adjusted, which controls the spindle motor inside the bed 1 to rotate, causing the chuck and mechanical parts to rotate. Simultaneously, the Z-axis motor on the bed 1 drives the large slide 2 to move laterally, and the X-axis motor on the large slide 2 drives the small slide, tool post, and cutting tool to move longitudinally, thereby realizing CNC turning of the mechanical parts. Simultaneously, the chips generated during turning fall into the chip conveyor 4. The chip baffle 10 blocks the flying chips to prevent injury. At the same time, the motor 81 rotates, and the output shaft of the motor 81 drives the roller 83 to rotate circumferentially through the rotating disk 82. The roller 83 gradually contacts and strikes the support plate 9, and the roller 83, through the support plate 9, drives the chip conveyor. The plate 4 rotates counterclockwise around the support shaft 3, pulling the tension spring 5. At the same time, the chip conveyor 4 drives the support bar 6 to separate from the rubber column 7. After the roller 83 separates from the support plate 9, the tension spring 5 drives the chip conveyor 4 and the support bar 6 to reset. The support bar 6 impacts the rubber column 7. As the motor 81 runs, the chip conveyor 4 is struck and vibrates. The chip conveyor 4 is tilted downward from front to back, which can cause the waste chips to slide backward into the chip collection tray 15. After use, the chip collection tray 15 can be pulled out backward by the handle 16 for cleaning. When adjusting the lathe, the rectangular bar 11 can be pulled upward. The rectangular bar 11 drives the positioning bar 12 to move upward and squeeze the spring plate 13. The lower end of the rectangular bar 11 separates from the chip conveyor 4. The chip baffle 10 can be rotated and folded. The chip baffle 10 does not cover the processing position, which is convenient for the adjustment of the lathe.

[0017] It is worth noting that the lathe controller 17 and motor 81 disclosed in the above embodiments can be freely configured according to the actual application scenario. The lathe controller 17 can be a lathe controller of model GSK928TE, and the motor 81 can be a permanent magnet synchronous motor of model AH60KTYZ-K8165 / YX25W 220V5R. The lathe controller 17 controls the operation of the motor 81 using methods commonly used in the prior art.
