[0003] The feed mechanism of existing CNC high-speed spline shaft milling machines usually only has adjustment function, which makes it difficult to simultaneously realize the directional collection and treatment of metal chips generated during the spline shaft grooving process. This causes the metal chips to scatter everywhere, increasing the difficulty of cleaning. Furthermore, the chips mix into the cutting fluid, further increasing the difficulty of cutting fluid recycling. Summary of the Invention

[0010] Furthermore, one end of the magnetic rod extends to the outside of the housing, and the first drive unit includes a third motor mounted on the back of the housing and a first pulley connected to two adjacent magnetic rods.

The output shaft of the fourth motor is also connected to one of the second lead screws by a second pulley.
[0012] Furthermore, the chip removal unit includes a chip removal channel installed on the front of the housing, a sealing plate slidably installed inside the chip removal channel, and multiple springs fixed to the outer wall of the sealing plate on the side away from the magnetic suction rod. Multiple push rods are fixed to the side of the pusher block near the chip removal channel. The front of the box has an opening that connects to the slag discharge channel, and a sealing plate is used to seal the opening. The other end of the spring is fixedly connected to the inner wall of the slag discharge channel; The bottom of the slag discharge channel extends to the outside of the base.

[0018] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.
[0019] Example 1: Please refer to Figure 1 - Figure 8A feed mechanism for a CNC high-speed spline shaft milling machine includes a base 1 and a feed mechanism. The feed mechanism includes: a four-jaw chuck 2, which is mounted on one side of the top of the base 1. The four-jaw chuck 2 is existing technology and is used to clamp the spline shaft and drive the spline shaft to rotate; a slide 3, which is slidably mounted on the top of the base 1. A milling cutter assembly 4 is mounted on the top of the slide 3. The milling cutter assembly 4 is existing technology and is used to machine keyways. The milling cutter assembly 4 is also equipped with a cooling structure for continuously supplying cutting fluid to the machining position; a translation assembly, which is mounted on the outer wall of the base 1 and is used to drive the slide 3 to move; a balance support assembly 5, which is mounted on the other side of the top of the base 1. The balance support assembly 5 is existing technology and is used to provide end support for the spline shaft; and an auxiliary support assembly 6, which is mounted on the top of the slide 3. The auxiliary support assembly 6 is existing technology and is used to support the outer wall on one side of the spline shaft machining position. In this embodiment, the spline shaft is made of carbon steel and has magnetic properties. During machining, the shaft to be machined is clamped and fixed by the four-jaw chuck 2, and the end of the shaft is supported by the balance support assembly 5 without affecting the rotation of the shaft. Then, the drive slide 3 and the milling cutter assembly 4 and auxiliary support assembly 6 on top are moved to the keyway machining position. The auxiliary support assembly 6 provides abutment support to one side of the machining position without affecting the rotation of the shaft. The four-jaw chuck 2 is controlled to drive the shaft to rotate, and the shaft is machined by the milling cutter assembly 4 to obtain the spline shaft.
[0020] The diversion and chip removal assembly includes a housing 7 installed at the bottom of the slide 3, multiple fixed seats 8 installed inside the housing 7 along the height direction of the housing 7, two graded chip removal components installed on the multiple fixed seats 8, and an adjustment component installed above the fixed seats 8. The translation assembly includes a first lead screw 9 rotatably connected to the outer wall of the base 1 along the length direction of the base 1 and a first motor 10 installed on the outer wall of the base 1; the slide 3 is threaded onto the outside of the first lead screw 9; the output end of the first motor 10 is fixedly connected to one end of the first lead screw 9. When the first motor 10 drives the first lead screw 9 to rotate forward, it drives the slide block 3 to slide to the right along the top of the base 1. When the first motor 10 drives the first lead screw to rotate in reverse, it drives the slide block 3 to slide to the left along the top of the base 1.
[0021] A chip collection cover 11 is installed on the top of the slide block 3, and a funnel-shaped chip guide groove 12 is opened inside the slide block 3. The chip collection cover 11, the chip guide groove 12 and the housing 7 are connected. Metal chips generated during the machining process gather inside the chip collection cover 11 and flow downward with the cutting fluid. When passing through the chip guide groove 12, they flow to the center of the guide plate 13.
[0022] The adjustment components include a guide plate 13 rotatably connected inside the housing 7 and a second motor 14 mounted on the outer wall of the housing 7; the output shaft of the second motor 14 extends into the interior of the housing 7, and the guide plate 13 is fixedly sleeved on the outside of the output shaft of the second motor 14. The second motor 14 is controlled to drive the guide plate 13 to rotate in different directions. The tilt direction of the guide plate 13 can be adjusted, so that when the cutting fluid and metal chips flow to the center position of the guide plate 13, the cutting fluid and metal chips can be controlled to be processed through the left-side graded chip removal component or the right-side graded chip removal component.
[0023] The graded chip removal component includes, from top to bottom, guide channels 15 respectively opened inside multiple fixed seats 8, magnetic suction rods 16 rotatably connected inside the guide channels 15, a first drive unit for driving the multiple magnetic suction rods 16 to rotate, pusher blocks 17 sleeved on the outside of the magnetic suction rods 16, a second drive unit for driving the multiple pusher blocks 17 to move, and a chip removal unit installed on the front of the housing 7; the outer wall of the pusher block 17 is in contact with the inner wall of the guide channel 15; a triangular baffle plate 18 is provided above each of the multiple magnetic suction rods 16, and one end of the magnetic suction rod 16 extends to the outside of the housing 7; the first drive unit includes a third motor 19 installed on the back of the housing 7 and a first belt drivingly connected between two adjacent magnetic suction rods 16. Wheel 20, third motor 19 and one of the magnetic suction rods 16 are also connected by transmission through first pulley 20. The second drive unit includes a protective cover 21 fixed inside the guide channel 15, a second lead screw 22 rotatably connected inside the protective cover 21 and a fourth motor 23 installed on the back of the box 7. The protective cover 21 is located inside the baffle plate 18 and above the magnetic suction rod 16. The pusher block 17 is threaded onto the outside of the second lead screw 22. One end of the second lead screw 22 extends to the outside of the box 7. Two adjacent second lead screws 22 are connected by transmission through second pulley 24. The output shaft of the fourth motor 23 is also connected by transmission through second pulley 24 to one of the second lead screws 22. When the cutting fluid and metal chips are processed by the graded chip removal component on the left, as the cutting fluid and metal chips flow along the guide channel 15, the third motor 19 on the left, in conjunction with each first pulley 20, drives multiple magnetic suction rods 16 to rotate synchronously, magnetically attracting the metal chips in the cutting fluid. The multiple guide channels 15 and magnetic suction rods 16 arranged from top to bottom improve the adequacy of the magnetic attraction of metal chips in the cutting fluid. After a set usage time, the graded chip removal component on the left drives the guide plate 13 to rotate, allowing the cutting fluid and metal chips to pass through... The cutting fluid and metal chips are processed by the grading and chip removal component on the right. While the grading and chip removal component on the right is processing the cutting fluid and metal chips, the grading and chip removal component on the left is idle. At this time, by controlling the fourth motor 23 on the left to drive each second pulley 24 to drive each second lead screw 22 to rotate synchronously, the pusher block 17 slides forward along the inner wall of the guide groove 15, and gathers the metal chips adsorbed on the outside of the magnetic suction rod 16 forward. After moving to the set position, the metal chips on the outside of the magnetic suction rod 16 are discharged by cutting off the power to the magnetic suction rod 16. When the fourth motor 23 on the left side drives the second lead screw 22 to reverse, it drives the pusher block 17 to move backward and reset.
[0024] The chip removal unit includes a chip removal channel 25 installed on the front of the housing 7, a sealing plate 26 slidably installed inside the chip removal channel 25, and multiple springs 27 fixed to the outer wall of the sealing plate 26 on the side away from the magnetic suction rod 16. Multiple push rods 30 are fixed to the side of the push block 17 near the chip removal channel 25. An opening is provided on the front of the housing 7, communicating with the chip removal channel 25. The sealing plate 26 is used to seal the opening. The other end of the springs 27 is fixed to the inner wall of the chip removal channel 25. The bottom of the chip removal channel 25 extends to the base. Outside of the base 1, a slag collection tank 28 is provided below the slag discharge channel 25. A drain pipe 29 is installed on the bottom of one side of the base 1 to discharge the cutting fluid that is discharged through the inside of the housing 7. A movable groove is opened along the length of the bottom of the base 1. The slag discharge channel 25 moves inside the movable groove. A partition is installed inside the base 1. The slag discharge channel 25 is located on one side of the front of the partition, and the housing 7 is located on one side of the back of the partition. Therefore, the cutting fluid discharged from the inside of the housing 7 can only be discharged through the drain pipe 29 and will not enter the movable groove. The pusher block 17 slides forward along the inner wall of the guide channel 15, gathering the metal debris adsorbed by the magnetic suction rod 16 forward. When the top rod 30 abuts against the sealing plate 26, it starts to drive the sealing plate 26 to move forward, and the spring 27 is compressed accordingly. The metal debris enters the slag discharge channel 25. After the magnetic suction rod 16 is de-energized, the metal debris falls rapidly, passes through the slag discharge channel 25 and enters the slag collection tank 28. When the pusher block 17 moves backward to reset, the rebound force of the spring 27 drives the sealing plate 26 to move backward to reset.
[0025] Example 2: Please refer to Figure 9 - Figure 11This embodiment provides a technical solution based on embodiment 1: the diversion and chip removal assembly further includes two liquid control components symmetrically arranged on both sides of the magnetic suction rod 16; the liquid control component includes an electric push rod 31 installed inside one of the fixed seats 8, a main cylinder 32 installed on one side of the electric push rod 31, and multiple auxiliary cylinders 33 installed inside the fixed seat 8; a first piston 34 is installed inside the main cylinder 32, and the extended end of the electric push rod 31 is fixedly connected to the outer wall of one side of the first piston 34. The main cylinder 32 and the multiple auxiliary cylinders 33 are all connected by conduits 35; a second piston 36 is installed inside the auxiliary cylinder 33, and a grooved rod 37 is fixedly connected to the outer wall of the second piston 36 near the magnetic suction rod 16. The grooved rod 37 is non-magnetic, and the top end of the grooved rod 37 extends into the interior of the guide groove 15 and cooperates with the magnetic suction rod 16. The grooved rods 37 in the two liquid control components are staggered. When a certain graded chip removal component is idle, one of the electric push rods 31 in the graded chip removal component is extended, which drives the first piston 34 inside the main cylinder 32 to move away from the magnetic suction rod 16. The hydraulic oil inside the main cylinder 32 is introduced into each auxiliary cylinder 33 through multiple conduits 35. The second piston 36 inside the auxiliary cylinder 33 moves towards the magnetic suction rod 16 and drives each grooving rod 37 to abut against the outer wall of the magnetic suction rod 16. Thus, during the rotation of the magnetic suction rod 16, the metal chips outside the magnetic suction rod 16 are separated, so that the cutting fluid in the metal chips can be thrown out from the isolation position. Then, the electric push rod 31 is retracted, which drives the grooving rod 37 to retract. When the grooving rod 37 is retracted, the top of the grooving rod 37 is on the same inclined plane as the inner wall of the guide groove 15, which does not affect the movement of the subsequent push block 17. Then, another electric push rod 31 in the graded chip removal component is extended, which in turn drives another row of push rods 30 to abut against the outer wall of the magnetic suction rod 16. Since the two rows of grooved rods 37 are staggered, when the magnetic suction rod 16 rotates, the cutting fluid in the metal chips in other areas outside the magnetic suction rod 16 is thrown out from the isolation position again, which improves the adequacy of the separation between metal chips and cutting fluid.
[0026] Working principle: During machining, the shaft to be machined is clamped and fixed by the four-jaw chuck 2. The end of the shaft is supported by the balance support assembly 5 without affecting the rotation of the shaft. Then, the drive slide 3 and the milling cutter assembly 4 and auxiliary support assembly 6 on top are moved to the keyway machining position. The auxiliary support assembly 6 provides abutment support to one side of the machining position without affecting the rotation of the shaft. The four-jaw chuck 2 drives the shaft to rotate, and the milling cutter assembly 4 processes the shaft to obtain a spline shaft. The metal chips generated during the machining process are collected inside the chip collection cover 11 and flow downward with the cutting fluid. When passing through the chip guide groove 12, they flow to the center position of the guide plate 13. The second motor 14 is controlled to drive the guide plate 13 to rotate in different directions, and the tilt of the guide plate 13 can be adjusted. The angled direction allows control over whether the cutting fluid and metal chips are processed through the left-side or right-side graded chip removal component when they reach the center of the guide plate 13. When the cutting fluid and metal chips are processed through the left-side graded chip removal component, as they flow along the guide channel 15, the left-side third motor 19, in conjunction with each first pulley 20, drives multiple magnetic suction rods 16 to rotate synchronously, magnetically attracting the metal chips in the cutting fluid. The multiple guide channels 15 and magnetic suction rods 16 arranged from top to bottom improve the effectiveness of magnetically attracting the metal chips in the cutting fluid. After a set time, the left-side graded chip removal component drives the guide plate 13 to rotate, allowing the cutting fluid and metal chips to pass through the right-side graded chip removal component. The chip removal components process the cutting fluid and metal chips. While the right-side chip removal component is handling the cutting fluid and metal chips, the left-side chip removal component is idle. At this time, one of the electric push rods 31 in the chip removal component is extended, causing the first piston 34 inside the main cylinder 32 to move away from the magnetic suction rod 16. This allows hydraulic oil inside the main cylinder 32 to be introduced into each auxiliary cylinder 33 through multiple conduits 35. The second piston 36 inside the auxiliary cylinder 33 then moves closer to the magnetic suction rod 16, causing each grooved rod 37 to abut against the outer wall of the magnetic suction rod 16. This isolates the metal chips outside the magnetic suction rod 16 during its rotation, allowing the cutting fluid in the metal chips to be ejected from the isolated position. Then, the electric push rod is controlled... 31 retracts, and then another electric push rod 31 in the graded chip removal component extends, thereby driving another row of top rods 30 to abut against the outer wall of the magnetic suction rod 16. Since the two rows of grooved rods 37 are staggered, when the magnetic suction rod 16 rotates, the cutting fluid in the metal debris in other areas outside the magnetic suction rod 16 is thrown out from the isolation position, improving the fullness of the separation between metal debris and cutting fluid. Then, by controlling the fourth motor 23 on the left to drive each second lead screw 22 to rotate synchronously in the same direction as each second pulley 24, the pusher block 17 slides forward along the inner wall of the guide groove 15, gathering the metal debris adsorbed outside the magnetic suction rod 16 forward. When the top rod 30 abuts against the sealing plate 26, it begins to drive the sealing plate 26 to move forward, and the spring 27 is compressed accordingly.Metal scraps enter the slag discharge channel 25. After the magnetic suction rod 16 is de-energized, the metal scraps fall rapidly, pass through the slag discharge channel 25, and enter the slag collection tank 28. When the pusher block 17 moves backward to reset, the rebound force of the spring 27 drives the sealing plate 26 to move backward to reset.
