[0029] The first embodiment of this utility model, referred to... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a small ball milling machine includes a frame 1, which serves as the main framework of the ball milling machine and provides an installation location for other components. A dovetail slide 101 is located on the top left side of the frame 1. An organic bed plate 7 is slidably mounted on the upper part of the dovetail slide 101.

A material ejection mechanism 5 is located at the right end of the T-shaped shaft tube 301, and a three-jaw chuck 4 is fixedly mounted at the left end of the T-shaped shaft tube 301, capable of clamping and fixing the material. Preferably, as shown... Figure 4 , Figure 6 , 7 and Figure 8 As shown, the milling assembly includes a mounting frame 701 and a second motor 705. The mounting frame 701 and the second motor 705 are respectively mounted on the upper part of the machine tool headstock 7. A milling spindle 702 is rotatably mounted on the upper end of the mounting frame 701. A third pulley 704 and a milling cutter 703 are respectively mounted on the left and right ends of the milling spindle 702. A fourth pulley 706 is mounted on the left end of the output shaft of the second motor 705. The third pulley 704 and the fourth pulley 706 are connected by a belt drive. Preferably, it also includes a first motor 10, a first pulley 11, and a second pulley 12. The first motor 10 is mounted on the top of the machine tool headstock 3, and the first pulley 11 is mounted on the outer end of the output shaft of the first motor 10. The second pulley 12 is sleeved on the outside of the T-shaped shaft tube 301. The first pulley 11 and the second pulley 12 are connected by belt drive. During ball milling, the material is clamped and fixed by the three-jaw chuck 4. Then, the second motor 705 drives the milling spindle 702 to rotate through the third pulley 704, the fourth pulley 706 and the belt. The milling cutter 703 on the milling spindle 702 begins to mill the material. At the same time, the first motor 10 drives the T-shaped shaft tube 301 to rotate through the first pulley 11, the second pulley 12 and the belt, thereby driving the three-jaw chuck 4 and the material to rotate, so as to facilitate the rotational milling of the material and thus realize the ball head processing.

[0030] The second embodiment of this utility model is described below. Figure 5 and Figure 6As shown, the spring mechanism 5 includes a drive bushing 502 and a first spring 503. The drive bushing 502 is slidably disposed outside the T-shaped shaft tube 301. A clutch ball 504 is elastically disposed in the mounting cavity opened at the outer end of the inner arc surface of the drive bushing 502 through a clutch spring. The spring rod 505 is slidably disposed inside the T-shaped shaft tube 301. The spring rod 505 is elastically connected to the T-shaped shaft tube 301 through the first spring 503. The clutch ball 504 engages with a groove opened on the outside of the spring rod 505. The machine headstock 3... A power assembly for moving the drive shaft sleeve 502 is provided. Preferably, the power assembly includes a guide rod 13, a mounting base 14, and a first cylinder 15. The mounting base 14 is rotatably mounted on the top of the machine tool headstock 3. The first cylinder 15 is fixedly mounted on the outer end of the mounting base 14. The telescopic end of the first cylinder 15 is hinged to the drive ring 501 rotatably mounted on the outside of the drive shaft sleeve 502 via a hinge. The guide rod 13 is slidably mounted on the upper rear side of the machine tool headstock 3. The outer end of the guide rod 13 is hinged to the drive ring 501 rotatably mounted on the drive shaft sleeve 502 via a hinge. The moving ring 501 is hinged. After the ball end milling is completed, the three-jaw chuck 4 releases the material it is holding. At this time, the material is in the center hole of the three-jaw chuck 4. The extension end of the first cylinder 15 extends and pushes the drive sleeve 502 to slide along the T-shaped shaft tube 301 through the drive ring 501. Because the clutch ball 504 engages with the groove on the outside of the spring rod 505, the spring rod 505 moves synchronously with the drive sleeve 502. At this time, the first spring 503 is stretched to store force. The elastic force inside the first spring 503 is large. When the clutch ball 504 and the spring rod 505 are engaged, the spring rod 505 disengages from the clutch ball 504, the first spring 503 contracts, and the spring rod 505 moves quickly to impact the material, thereby ejecting the material from the three-jaw chuck 4 to achieve automatic feeding. Subsequently, the telescopic end of the first cylinder 15 contracts, driving the drive bushing 502 to move in the opposite direction. Under the limiting action of the spring rod 505 and the inner convex ring of the T-shaped shaft tube 301, the clutch ball 504 re-engages with the groove on the outside of the spring rod 505.

[0031] The third embodiment of this utility model is described below. Figure 1 , Figure 2 and Figure 7As shown, a fixed base 8 is fixedly installed on the left side of the upper surface of the mounting base 2. A feeding assembly 9 is fixedly installed on the top of the fixed base 8. Preferably, the feeding assembly 9 includes a feeding plate 901, which is fixedly installed on the top of the fixed base 8. A third cylinder 902 is installed at the right end of the feeding plate 901. The telescopic end of the third cylinder 902 is fixedly connected to a guide slider 903 slidably installed on the feeding plate 901. A feeding rod 904 is fixedly installed at the right end of the slider 903. The feeding rod 904 is located in a material guide groove opened on the right side of the feeding plate 901. Preferably, a feeding rod 904 is fixedly installed at the right end of the feeding plate 901. A fixed guide rail 905 is provided, on which a feeding baffle 906 is slidably mounted.

The feeding baffle 906 and the fixed block 908 mounted on the fixed guide rail 905 are elastically connected by a rebound spring. Preferably, a hopper assembly 6 is fixedly mounted on the upper rear side of the fixed base 8. A top plate 601 is slidably mounted on the lower part of the hopper assembly 6. The lower end of the top plate 601 is connected to the telescopic end of the second cylinder 602 fixedly mounted on the lower part of the hopper assembly 6 via a top connecting plate. In a fixed connection, preferably, the upper right side of the mounting base 2 is provided with a lead screw module 201 for driving the machine headstock 3 to move back and forth, and a position sensing switch 202 for sensing the running position of the machine headstock 3. Preferably, the upper part of the fixed guide rail 905 is provided with a detection probe for sensing materials via a mounting bracket. During ball milling, the lead screw module 201 moves the machine headstock 3 and the components above it. With the cooperation of sensing the machine headstock 3, the three-jaw chuck 4 moves to the position corresponding to the feeding baffle 906, and puts the material to be processed into the hopper assembly 6. The second cylinder 60 The telescopic end of cylinder 2 drives the top plate 601 to move up and down, thereby lifting the material inside the hopper assembly 6 and allowing the material to enter the material guide groove on the feeding plate 901. Cylinder 902 pushes the feeding rod 904 to move through the guide slider 903. The feeding rod 904 pushes the material to move. At the same time, the outer end of the feeding rod 904 lifts the feeding baffle 906 through the small bearing set at the outer end of the guide seat 907, thereby pushing the material out into the three-jaw chuck 4. The three-jaw chuck 4 clamps and fixes the material. Then, the lead screw module 201 moves with the upper component to the milling cutter 703, and the milling assembly runs to start milling the material.
