A gear 4 315 is also fixedly connected to the right side of the gear 314 and on the outer circumference of the rotating column 313, and the gear 4 315 is meshed with the movable sleeve 306. A fixed plate 1 316 is fixedly connected to the inner upper wall of the fixed box 2, and one end of the rotating column 2 308 away from the driving motor 2 307 is rotatably connected to the bottom of the fixed plate 1 316. The rotating column 1 304 and the movable sleeve 306 both extend to the outside of the fixed box 2, and the rotating column 1 304 is away from the gear 315. One end of wheel two 303 is fixedly connected to a rotating box 318 by a bolt 317, and a double-thread screw 319 is rotatably connected inside the rotating box 318. A gear five 320 is fixedly connected to the middle of the outer circumference of the double-thread screw 319, and the gear five 320 is meshingly connected to the movable sleeve 306. The outer circumference of the double-thread screw 319 is threadedly connected to threaded sleeves 321 on both sides, and the outer circumferences of the threaded sleeves 321 on both sides are fixedly connected to connecting plates two 322. The connecting plates two 322 on both sides are slidably connected to the inside of the rotating box 318, and the tops of the connecting plates two 322 on both sides are fixedly connected to clamps 323, and the clamps 323 on both sides are movably connected to the workpiece 4 to be processed.

[0049] In this implementation case, in real life, during the milling process of spiral bevel gears, it is not only necessary to fix the workpiece 4 to be processed on the top of the operating bed 1 to prevent the spiral bevel gears from shifting during the processing, but also it is necessary to continuously adjust the rotation of the workpiece 4 to be processed, so as to perform equidistant milling on the workpiece 4. When using the milling machine, the staff first turns on the drive motor 2 307, and the drive motor 2 307 drives the rotating column 2 308 to rotate, thereby driving the fixed sleeve 310 to rotate. Since the fixed sleeve 310 is meshed with the gear 314, the gear 314 is driven to rotate, and the gear 314 drives the rotating column 313 to rotate, and the rotating column 313 drives the gear 4 315 to rotate. When the gear 4 315 rotates, it drives the movable sleeve 306 to move upward along the rotating column 1 304 The movable sleeve 306 drives the gear 5 320 to rotate. When the gear 5 320 rotates, it drives the double-thread screw 319 to rotate in the rotating box 318, and then the connecting plate 2 322 slides close through the threaded sleeve 321, so that the two clamping plates 323 are effectively clamped on the outer surface of the workpiece 4 to avoid the workpiece 4 from being offset during the processing, resulting in processing failure. When one of the teeth of the workpiece 4 is processed, the drive motor 1 301 is turned on, and the drive motor 1 301 drives the gear 1 302 to rotate, and then drives the meshing gear 2 303 to rotate. When the gear 2 303 rotates, it drives the rotating column 1 304 to rotate, and then drives the rotating box 318 to rotate through the bolt 317, so that the workpiece 4 to be processed is rotated to another angle that needs to be processed.

[0050] The outer surface of the rotating and clamping mechanism 3 is movably connected to the workpiece 4 to be processed, the two opposite sides of the top of the operating bed 1 are fixedly connected with connecting plates 102, a horizontal moving mechanism 5 is arranged between the two connecting plates 102, the top of the horizontal moving mechanism 5 is fixedly connected with an operating box 6, the outer surface of the operating box 6 is provided with a notch 601, the interior of the notch 601 is provided with a vertical moving mechanism 7, the horizontal moving mechanism 5 includes a driving motor 3 501 fixedly installed on the outside of the left connecting plate 102, the output end of the driving motor 3 501 extends to the inside of the left connecting plate 102, and is fixedly connected with a threaded rod 502, the threaded rod 502 is rotatably connected between the connecting plates 102 on both sides, and two sets of sliding rods 503 are fixedly connected between the connecting plates 102 on both sides.

[0051] In this implementation case, after the workpiece 4 to be processed is effectively fixed on the top of the operating bed 1, the drive motor 3 501 is turned on, and the drive motor 3 501 drives the threaded rod 1 502 to rotate, and then the movable block 1 504 is moved through the guidance of the slide rod 1 503, thereby driving the milling cutter 15 inside the operating box 6 to move to the specified horizontal position, and then the drive motor 4 701 is turned on, and the drive motor 4 701 drives the threaded rod 2 702 to rotate, and then the movable block 2 704 is driven to descend to a suitable height through the guidance of the slide rod 2 703, so that the milling cutter 15 reaches the vicinity of the workpiece 4 to be processed, thereby preparing for the next operation.

[0052] A clamping mechanism 14 is provided on the outer side of the rotating plate 12, and a milling cutter 15 is movably connected to the outer surface of the clamping mechanism 14.

The sliding rod 1407 extends to the outside of the connecting box 1401 through the through slots 1408, and the sliding rod 1407 is slidably connected to the connecting box 1401. The bottom of the milling cutter 15 is fixedly connected with a fixing plate 3 1409. The bottom four corners of the fixing plate 3 1409 are fixedly connected with fixing parts 1410. The outer surface of the fixing part 1410 is provided with slots 1411, and the slots 1411 are adapted to the sliding rod 1407.

[0053] In this embodiment, when the milling cutter 15 needs to be quickly installed with the rotating plate 12, the staff first presses the limit blocks 1406 on both sides inward, and the limit blocks 1406 drive the movable rod 1404 to move inward along the through groove 1 1405, and then drive the sliding rod 1407 to move inward along the through groove 2 1408, and the spring 1403 is in a compressed state. At this time, the fixed plate 3 1409 on the lower side of the milling cutter 15 is covered on the top of the connection box 1401, and then the staff releases the limit blocks 1406 on both sides. Due to the thrust of the spring 1403, the sliding rod 1407 is inserted into the slot 1411 opened in the four-corner fixing parts 1410, so that the milling cutter 15 and the rotating plate 12 are quickly installed. When the milling cutter 15 needs to be replaced or repaired, it is only necessary to press the limit blocks 1406 on both sides to disengage the sliding rod 1407 from the slot 1411, and then push the milling cutter 15 upward to complete the quick disassembly of the milling cutter 15 and the rotating plate 12, avoiding the time-consuming and labor-intensive separation or installation of the milling cutter 15 in real life.

[0054] A fixed plate 2 10 is provided on the front side of the vertical moving mechanism 7, and a driving motor 6 11 is fixedly connected to the right side surface of the fixed plate 2 10, and the output end of the driving motor 6 11 extends to the left side of the fixed plate 2 10 and is fixedly connected to a rotating plate 12, and an annular groove 1001 is provided on the left side surface of the fixed plate 2 10, and a slider 13 is slidably connected inside the annular groove 1001, and the end of the slider 13 away from the fixed plate 2 10 is fixedly connected to the rotating plate 12, and an installation groove 7041 is provided on the outer side of the movable block 2 704, and a driving motor 5 8 is fixedly installed inside the installation groove 7041, and the output end of the driving motor 5 8 extends to the outer side of the movable block 2 704 and is fixedly connected to a connecting seat 9, and the end of the connecting seat 9 away from the driving motor 5 8 is fixedly connected to the fixed plate 2 10.

[0055] In this embodiment, after the preparation work of the gear milling machine is completed, the drive motor five 8 is turned on, and the drive motor five 8 drives the connecting seat 9 to rotate, and then drives the fixed plate two 10 to rotate, so that the milling cutter 15 is adjusted to an inclination angle suitable for the workpiece 4 to be processed, and then the drive motor six 11 is turned on, and the drive motor six 11 drives the rotating plate 12 to rotate, and then drives the milling cutter 15 to rotate, so as to mill the outer surface of the workpiece 4 to be processed. During the rotation of the fixed plate two 10, the slider 13 slides in the annular groove 1001, thereby increasing the stability of the rotation of the rotating plate 12 and the milling cutter 15.

Then the collection frame 23 moves to the bottom of the opposite sides of the workpiece 4 to be processed along the direction of the slide groove 103 through the wheel body 2302 at the bottom of the connecting frame 2301, and the coolant or the iron wire generated during processing passes through the outer surface of the workpiece 4 to be processed and the milling cutter 15 and slides into the inside of the collection frame 23, thereby avoiding the coolant or iron wire from scattering on the ground and causing dirt and mess. The staff can control each drive motor through the control panel 22 to meet the customer needs of various workpieces 4 to be processed.

[0058] Working principle and use process of this device: In real life, when milling spiral bevel gears, it is not only necessary to fix the workpiece 4 to be processed on the top of the operating bed 1 to prevent the spiral bevel gears from shifting during the processing, but also necessary to continuously adjust the rotation of the workpiece 4 to be processed, so as to perform equidistant milling on the workpiece 4. When using the milling machine, the staff first turns on the drive motor 2 307, and the drive motor 2 307 drives the rotating column 2 308 to rotate, thereby driving the fixed sleeve 310 to rotate. Since the fixed sleeve 310 is meshed with the gear 314, the gear 314 is driven to rotate, and the gear 314 drives the rotating column 313 to rotate, and the rotating column 313 drives the gear 4 315 to rotate. When the gear 4 315 rotates, it drives the movable sleeve 306 along the rotating column 314. 04 slides upward, so that the movable sleeve 306 drives the gear five 320 to rotate. When the gear five 320 rotates, it drives the double-thread screw 319 to rotate in the rotating box 318, and then the connecting plate two 322 slides close through the threaded sleeve 321, so that the two clamping plates 323 are effectively clamped on the outer surface of the workpiece 4 to avoid the workpiece 4 from being offset during the processing, resulting in processing failure. When one of the teeth of the workpiece 4 is processed, the drive motor 1 301 is turned on, and the drive motor 1 301 drives the gear 1 302 to rotate, and then drives the meshing gear 2 303 to rotate. When the gear 2 303 rotates, it drives the rotating column 1 304 to rotate, and then drives the rotating box 318 to rotate through the bolt 317, so that the workpiece 4 to be processed is rotated to another angle that needs to be processed.

[0059] After the workpiece 4 to be processed is effectively fixed on the top of the operating bed 1, the driving motor 3 501 is turned on, and the driving motor 3 501 drives the threaded rod 1 502 to rotate, and then the movable block 1 504 is moved through the guidance of the slide bar 1 503, thereby driving the milling cutter 15 inside the operating box 6 to move to the specified horizontal position, and then the driving motor 4 701 is turned on, and the driving motor 4 701 drives the threaded rod 2 702 to rotate, and then the movable block 2 704 is driven to descend to a suitable height through the guidance of the slide bar 2 703, so that the milling cutter 15 reaches the vicinity of the workpiece 4 to be processed, thereby preparing for the next operation.

[0060] When the milling cutter 15 needs to be quickly installed with the rotating plate 12, the staff first presses the limit blocks 1406 on both sides inward, and the limit blocks 1406 drive the movable rod 1404 to move inward along the through slot 1 1405, and then drive the sliding rod 1407 to move inward along the through slot 2 1408. The spring 1403 is in a compressed state. At this time, the fixed plate 3 1409 on the lower side of the milling cutter 15 is covered on the top of the connecting box 1401, and then the staff releases the limit blocks 1406 on both sides. The thrust of the spring 1403 causes the sliding rod 1407 to be inserted into the slot 1411 opened in the four corner fixing parts 1410, so that the milling cutter 15 and the rotating plate 12 can be quickly installed. When the milling cutter 15 needs to be replaced or repaired, it is only necessary to press the limit blocks 1406 on both sides to disengage the sliding rod 1407 from the slot 1411, and then push the milling cutter 15 upward to complete the rapid disassembly of the milling cutter 15 and the rotating plate 12, thereby avoiding the time-consuming and labor-intensive situation of separating or installing the milling cutter 15 in real life.

[0061] When the preparation work of the gear milling machine is completed, the driving motor 5 8 is turned on, and the driving motor 5 8 drives the connecting seat 9 to rotate, and then drives the fixed plate 2 10 to rotate, so that the milling cutter 15 is adjusted to an inclination angle suitable for the workpiece 4 to be processed, and then the driving motor 6 11 is turned on, and the driving motor 6 11 drives the rotating plate 12 to rotate, and then drives the milling cutter 15 to rotate, so as to mill the outer surface of the workpiece 4 to be processed. During the rotation of the fixed plate 2 10, the slider 13 slides in the annular groove 1001, thereby increasing the stability of the rotation of the rotating plate 12 and the milling cutter 15.

[0062] During the gear milling machine processing, the water pump 18 will extract the coolant in the coolant box 16 through the connecting pipe 17, and then spray it to the outer surface of the milling cutter 15 and the workpiece 4 to be processed through the hose 19, the hard pipe 20 and the spray head 21, so as to cool the milling cutter 15 and the workpiece 4 to be processed, so as to avoid the problem that the milling cutter 15 and the workpiece 4 are too hot and affect the quality of the workpiece 4 to be processed or cause damage to the milling cutter 15. Then the collection frame 23 moves to the bottom of the opposite sides of the workpiece 4 to be processed along the direction of the slide groove 103 through the wheel body 2302 at the bottom of the connecting frame 2301, and the coolant or the iron wire generated during the processing will slide into the inside of the collection frame 23 after passing through the outer surface of the workpiece 4 to be processed and the milling cutter 15, so as to avoid the coolant or the iron wire from scattering on the ground and causing dirt and mess. The staff can control each drive motor through the control panel 22 to meet the customer needs of various workpieces 4 to be processed.
