[0018] Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 This is a schematic diagram of the positioning part of the rubber sleeve of this utility model.

[0019] As attached Figure 1 As shown, an automatic milling machine for rubber sleeve shafts includes a vertical base 1, a bottom positioning seat 2, a positioning seat lifting mechanism 3, a lifting part 4, a milling part 5, a rubber sleeve positioning part 6, and a mandrel 7. The positioning seat lifting mechanism 3 and the lifting part 4 are installed on the vertical base 1. The positioning seat lifting mechanism 3 is located below the lifting part 4. The milling part 5 and the rubber sleeve positioning part 6 are installed on the lifting part 4. The bottom positioning seat 2 is installed on the positioning seat lifting mechanism 3. The mandrel 7 is slidably connected to the top of the vertical base 1. A spring is connected between the top of the vertical base 1 and the mandrel 7. The mandrel 7 is located between the milling part 5 and the rubber sleeve positioning part 6.

[0020] The positioning seat lifting mechanism 3 and the lifting part 4 are both composed of a motor 31, a rack 32, a slide 33, and gears. A rack 32 is fixed on the vertical base 1. The gears of the lifting mechanism 3 and the lifting part 4 mesh on the rack 32. The gears are fixed on the output shaft of the motor 31. The body of the motor 31 is fixed on the slide 33. The slide 33 is slidably connected to the vertical base 1. A bottom positioning seat 2 is fixed on the slide 33 of the positioning seat lifting mechanism 3. A milled hole part 5 and a rubber sleeve positioning part 6 are installed on the slide 33 of the lifting part 4.

[0021] The positioning seat lifting mechanism 3 drives the bottom positioning seat 2 to rise and fall, which can be used to adapt to shafts of different lengths.

[0022] The motor 31 drives the gear to rotate, and the gear rolls along the rack 32, which in turn carries the slide 33 to move linearly up and down on the vertical base 1.

[0023] The milling section 5 includes a milling cutter 51, a milling cutter rotary motor 52, and a horizontal linear module 53. The cylinder of the horizontal linear module 53 is fixed on the slide 33 of the lifting section 4, and the slide of the horizontal linear module 53 is fixed on the body of the milling cutter rotary motor 52. The milling cutter 51 is fixed on the output shaft of the milling cutter rotary motor 52.

[0024] The horizontal linear module 53 can drive the milling cutter 51 to move horizontally in a linear manner, while the milling cutter rotary motor 52 can drive the milling cutter 51 to rotate.

[0025] As attached Figure 2 As shown, the rubber sleeve positioning part 6 includes a frame 61, a positioning pin 62, a cylinder 63, a spring 64, a slider 65, and a handle 66. The frame 61 is fixed on the slide block 33 of the lifting part 4. The positioning pin 62 is slidably connected to the frame 61 and fixed together with the slider 65. The handle 66 is rotatably connected to the frame 61. The handle 66 is provided with a protrusion for pushing the slider 65. The spring 64 is connected between the slider 65 and the piston rod of the cylinder 63. The cylinder body of the cylinder 63 is fixed on the frame 61.

[0026] The extension and retraction of the piston rod of cylinder 63 can drive slider 65 to move the positioning pin 62 horizontally to a set position. Turning handle 66 can push slider 65 and positioning pin 62 horizontally toward spring 64, at which time spring 64 is in a compressed state. When the operator releases handle 66, spring 64 rebounds and pushes slider 65 and positioning pin 62 to move in the opposite direction.

[0027] A displacement sensor 8 is mounted on the top of the vertical base 1, and a contact plate 9 for contacting the displacement sensor 8 is fixed on the spindle 7. When installing the shaft, first place the bottom of the shaft against the bottom positioning seat 2, then push the spindle 7 upwards, leaving enough space for the shaft to be vertical; at this time, the spring is compressed. When the top of the shaft is directly below the spindle 7, release the spindle 7. The spring will then push the spindle 7 downwards until the spindle 7 abuts against the top of the shaft. The contact plate 9 will move up and down with the spindle 7, pushing the detection head of the displacement sensor 8, which will then sense the length of the shaft.

[0028] The bottom end of the spindle 7 is provided with a step for supporting the top end of the shaft, and the top end of the bottom positioning seat 2 is provided with a step for supporting the bottom of the shaft.

[0029] The working method of this application is as follows: First, the rubber sleeve is fitted onto the mandrel 7. The cylinder 63 of the rubber sleeve positioning part 6 drives the positioning pin 62 to engage with the rubber sleeve, and the spring 64 applies pressure to the positioning pin 62. As the rubber sleeve moves, when the positioning pin 62 aligns with the opening on the side of the rubber sleeve, the positioning pin 62 will insert into the opening, thereby achieving the positioning of the rubber sleeve. Next, the shaft is placed between the bottom positioning seat 2 and the mandrel 7. Then, the lifting part 4 drives the milling part 5 and the rubber sleeve positioning part 6 to move down. The rubber sleeve positioning part 6 will transfer the rubber sleeve from the mandrel 7 to the shaft. At this time, the milling part 5 uses the milling cutter 51 to mill holes in the rubber sleeve and the shaft that are fitted together. Finally, the handle 66 is turned to push the positioning pin 62 away from the rubber sleeve, and the lifting part 4 drives the milling part 5 and the rubber sleeve positioning part 6 to move up and reset.
