A plurality of mounting seats 14 are fixedly connected to the top of the lifting frame 13, and a first ball bearing 15 is provided on the top of the mounting seat 14. A centering mechanism for centering and clamping a spline shaft is provided on the side wall of the lifting frame 13, and a support mechanism for supporting the suspended end of the spline shaft is provided on the side wall of the lifting frame 13.

[0035] The support mechanism includes an L-shaped plate 1602, which is connected to the side wall of the fixed frame 11 via a first moving module 1601.

[0036] The rotating mechanism includes a first lifting block 207, which is connected to the top of the L-shaped plate 1602 via a second lifting module 206. An arc-shaped first guide rail 201 is fixedly connected to the side wall of the first lifting block 207, and a first sliding block 202 is slidably connected to the side wall of the first guide rail 201. The first sliding block 202 is fixed to the bottom of the rotating plate 1603, and an arc-shaped first gear ring 203 is embedded in the side wall of the first guide rail 201. A motor 204 is fixedly connected to the top of the rotating plate 1603, and a first gear 205 is fixedly connected to the output end of the motor 204. The first gear 205 and the first gear ring 203 are... When the ring 203 is engaged, the motor 204 is started. The motor 204 is a self-locking motor. The rotation of the motor 204 drives the rotation of the first gear 205, so that the first gear 205 can roll along the side wall of the first gear ring 203, thereby driving the first sliding block 202 to slide upward along the first guide rail 201. At this time, the rotating plate 1603 and the U-shaped plate 1604 can be rotated to a horizontal state. Furthermore, the first electromagnet 1605 maintains the attraction effect on the spline shaft. At this time, the spline section of the spline shaft can be axially supported, the axial force applied by the milling cutter can be offset, the deformation caused by the force can be avoided, and the machining quality can be guaranteed.

[0037] The centering mechanism is slidably connected to two sets of symmetrically arranged support frames 501 on the side wall of the fixed frame 11, and there are two support frames 501 in each set. The side wall of each support frame 501 is connected to a first moving block 503 through a second moving module 502, and an arc-shaped second guide rail 504 is fixedly inserted into the side wall of the first moving block 503. A V-shaped plate 505 is slidably connected to the side wall of the second guide rail 504. The rotation of the V-shaped plate 505 is driven by a driving mechanism. The side wall of the fixed frame 11 is provided with a centering component for centering the end of the spline shaft. First, the spline shaft is placed on the rotating platform 106. Then, the first lifting module 12 drives the lifting frame 13 to move upward, thereby driving the mounting base 14 and the first ball bearing 15 to move upward and lifting the spline shaft. The second moving module 502 drives the two first moving blocks 503 in the same group to move closer to each other, and drives the V-shaped plate 505 to move closer to each other. The end of the spline shaft slides on the surface of the second ball bearing 604, thereby gradually centering the spline shaft. Under the action of the first ball bearing 15, it is convenient to move and adjust the spline shaft.

[0038] The central component includes two sets of symmetrically arranged L-shaped frames 601 fixedly connected to the side wall of the fixed frame 11, with two L-shaped frames 601 in each set.

The symmetrical side walls of the push blocks 607 have slanted grooves 6. 08. A push rod 609 is fixedly connected to the side wall of the lifting frame 13, and the push rod 609 is inserted into the inclined groove 608. When the lifting frame 13 moves away from the fixed frame 11, it can drive the push rod 609 to slide upward along the inclined groove 608, thereby pushing the L-shaped frame 601 to slide along the side wall of the fixed frame 11. When the two ends of the spline shaft slide along the inclined plate 605 to the side wall of the push plate 603, it can push the push plate 603 to move away from the L-shaped frame 601. At the same time, it drives the first T-shaped guide rod 602 to move, and the first spring 606 is compressed. At this time, the spline shaft can be axially centered.

[0039] The pressure control mechanism includes two first sleeve rods 301 fixedly connected to the top of the rotating plate 1603, and a first sleeve 302 is sleeved on the side wall of the first sleeve rod 301.

A second spring 303 is sleeved on the side wall of each first sleeve 302, and a distance sensor 304 is fixedly inserted into the top of the rotating plate 1603. After centering and clamping, the L-shaped plate 1602 is moved by the first moving module 1601. At the same time, the rotating mechanism and the pressure control mechanism drive the U-shaped plate. 1604 and the first electromagnet 1605 move so that the first electromagnet 1605 moves to below the milled spline position at the suspended end of the spline shaft. Then, the second lifting module 206 drives the first lifting block 207 to move upward. At the same time, the rotation mechanism and pressure control mechanism drive the first electromagnet 1605 to move upward. When the first electromagnet 1605 is in contact with the bottom of the spline shaft, the second spring 303 is gradually compressed. At the same time, the distance sensor 304 detects and ensures the contact effect between the first electromagnet 1605 and the spline shaft.

[0040] The limiting mechanism includes a first mounting plate 401 fixedly connected to the bottom of the U-shaped plate 1604, and the side wall of the first mounting plate 401 is provided with a plurality of insertion holes 402. A fixing plate 403 is fixedly connected to the top of the rotating plate 1603, and two symmetrically arranged second sleeves 404 are fixedly connected to the side wall of the fixing plate 403. A second sleeve rod 405 is inserted into the second sleeve 404, and a second moving block 409 is fixedly connected to the other end of the second sleeve rod 405.

A reset spring 406 is sleeved on the side wall of each second sleeve 404. When the second electromagnet 407 is de-energized, the second electromagnet 407 no longer attracts the iron block 408. The second moving block 409 can move away from the fixed plate 403 under the action of the reset spring 406 and insert the pin 410 into the socket 402 for limiting. After limiting, the damping shaft coincides with the center of the first guide rail 201, ensuring that the first sliding block 202 can slide normally along the first guide rail 201.

[0041] The driving mechanism includes a second gear ring 701 with an arc shape fixedly connected to the side wall of the V-shaped plate 505, and a U-shaped block 702 fixedly connected to the side wall of the first moving block 503. A second gear 704 is rotatably connected to the side wall of the U-shaped block 702 via a rotating shaft 703, and the second gear 704 meshes with the second gear ring 701. The rotation of the rotating shaft 703 can also be directly driven by a motor. A rectangular tube 715 is fixedly connected to the side wall of the first lifting block 207, and an L-shaped rod 716 is inserted inside the rectangular tube 715. Two third sleeve rods 717 are fixedly connected to the side wall of the L-shaped rod 716, and a third sleeve 718 is fitted onto the side wall of the third sleeve rod 717. The other end of 18 is fixedly connected to a mounting cover 709, and a sliding plate 711 is slidably connected inside the mounting cover 709. A third spring 712 is fixedly connected between the sliding plate 711 and the mounting cover 709. Multiple triangular blocks 713 are fixedly connected to the side wall of the sliding plate 711. The top of the triangular blocks 713 is provided with an inclined surface 714. Two symmetrically arranged fourth sleeves 708 are fixedly connected to the bottom of the mounting cover 709. A fourth sleeve rod 707 is inserted into the fourth sleeve 708. The lower end of the fourth sleeve rod 707 is fixed to the side wall of the U-shaped block 702 through a connecting plate 706. Multiple arrayed rectangular blocks 705 are fixedly connected to the side wall of the rotating shaft 703. The side wall of 702 is provided with a limiting component for limiting the rotation shaft 703. When the spline shaft is clamped in the center, the first lifting block 207 moves upward. At the same time, the mounting cover 709 moves upward through the rectangular tube 715, L-shaped rod 716, third sleeve rod 717, and third sleeve 718. At this time, the inclined surface 714 abuts against the rectangular block 705, which can push the triangular block 713 into the mounting cover 709. At the same time, the third spring 712 is compressed. Under the action of the limiting component, the rotation shaft 703 will not rotate. After each keyway of the spline is completed, the U-shaped plate 1604 is rotated downward and reset by the rotating mechanism, so that the U-shaped plate 1604 In the vertically upward position, the first electromagnet 1605 is de-energized, and the second lifting module 206 drives the first lifting block 207 to move downward a certain distance, causing the first electromagnet 1605 to disengage from the spline shaft. At the same time, when the first lifting block 207 moves downward, it can drive the mounting cover 709 to move downward. When the bottom of the triangular block 713 abuts against the rectangular block 705, it can push the rotating shaft 703 to rotate at a certain angle. When the rotating shaft 703 rotates, it can drive the second gear 704 to rotate, thereby driving the V-shaped plate 505 to rotate along the second guide rail 504 through the second gear ring 701, and thus driving the spline shaft to rotate at a certain angle.

[0042] The limiting assembly includes a fixing block 803 fixedly connected to the side wall of the U-shaped block 702, and two symmetrically arranged second T-shaped guide rods 804 inserted into the bottom of the fixing block 803.

A fixing ring 801 is fixedly sleeved on the side wall of the rotating shaft 703, and the side wall of the fixing ring 801 has multiple arrayed arc-shaped grooves 802. When the rotating shaft 703 rotates, it can drive... The fixed ring 801 rotates, causing the arc-shaped block 805 to slide from the arc-shaped groove 802 and along the side wall of the fixed ring 801. At the same time, the fourth spring 806 is compressed. When the arc-shaped block 805 slides into another arc-shaped groove 802, the arc-shaped block 805 can abut against the arc-shaped groove 802 under the action of the fourth spring 806. At this time, the rotating shaft 703 can be limited, making it more stable and reliable. This makes it easier to automatically rotate the spline shaft when milling splines, which is more convenient and faster, and can improve the processing efficiency.

Under the action of the fifth spring 906, the grinding brush 905 can be kept in contact with the surface of the spline. At the same time, when the spline shaft rotates, the grinding brush 905 can be used to grind the burrs on the surface of the spline.

When the first lifting block 207 is raised or lowered, it can drive the second mounting plate 1001 to be raised or lowered. At this time, the push pin 1004 can rotate along the V-shaped groove 1002 and drive the second sliding block 907 to reciprocate on the third guide rail 901 through the connecting frame 1003, thereby driving the grinding brush 905 to reciprocate, so as to make the grinding more efficient and effective, and ensure the quality of milling splines.

[0045] Working principle: When it is necessary to mill splines and end faces of the spline shaft, the spline shaft is first placed on the rotating platform 106. Then, the first lifting module 12 drives the lifting frame 13 to move upward, thereby driving the mounting base 14 and the first ball bearing 15 to move upward and lifting the spline shaft. At the same time, when the lifting frame 13 moves away from the fixed frame 11, it can drive the push rod 609 to slide upward along the inclined groove 608, thereby pushing the L-shaped frame 601 to slide along the side wall of the fixed frame 11. When both ends of the spline shaft slide along the inclined plate 605 to the side wall of the push plate 603, it can push the push plate 603 to move away from the L-shaped frame 601. At the same time, it drives the first T-shaped guide rod 602 to move, and the first spring 606 is compressed. At this time, the spline shaft can be axially centered and its end can slide on the surface of the second ball bearing 604.

[0046] Next, the second moving module 502 drives the two first moving blocks 503 in the same group to move closer to each other, and drives the V-plates 505 to move closer to each other. The end of the spline shaft slides on the surface of the second ball 604, thereby gradually centering the spline shaft. Under the action of the first ball 15, it is convenient to move and adjust the spline shaft, and at the same time, it can reduce its wear. Finally, the V-plate 505 clamps the spline shaft radially, which facilitates the axial and radial centering clamping of the spline shaft, making it more convenient and faster, and ensuring the efficiency and effect of processing.

[0047] After the centering and clamping is completed, the first lifting module 12 drives the lifting frame 13 to move downward, so that the first ball 15 disengages from the spline shaft. At the same time, it can drive the push rod 609 to slide downward along the inclined groove 608, thereby pushing the push plate 603 to disengage from the end of the spline shaft.

[0048] Next, the L-shaped plate 1602 is moved by the first moving module 1601. At the same time, the rotating mechanism and the pressure control mechanism drive the U-shaped plate 1604 and the first electromagnet 1605 to move, so that the first electromagnet 1605 moves to below the milled spline position at the suspended end of the spline shaft. Then, the first lifting block 207 is moved upward by the second lifting module 206. At the same time, the rotating mechanism and the pressure control mechanism drive the first electromagnet 1605 to move upward. When the first electromagnet 1605 is in contact with the bottom of the spline shaft, the second spring 303 is gradually compressed. At the same time, the distance sensor 304 detects and ensures the contact effect between the first electromagnet 1605 and the spline shaft.

[0049] Next, the second electromagnet 407 is de-energized. After the second electromagnet 407 is de-energized, it no longer attracts the iron block 408. The second moving block 409 can move away from the fixed plate 403 under the action of the return spring 406 and insert the pin 410 into the socket 402 for limiting. The first electromagnet 1605 is energized and attracts to the surface of the spline shaft, which is more stable and reliable. When the milling cutter of the vertical milling head 102 gradually feeds to the top of the spline shaft, the first electromagnet 1605 can provide radial support to the spline shaft and counteract the radial force applied by the milling cutter, thus preventing the spline shaft from deforming.

[0050] When the milling cutter of the vertical milling head 102 moves axially, the motor 204 is started. The rotation of the motor 204 drives the rotation of the first gear 205, which allows the first gear 205 to roll along the side wall of the first gear ring 203. This drives the first sliding block 202 to slide upward along the first guide rail 201. At this time, the rotating plate 1603 and the U-shaped plate 1604 can be rotated to a horizontal state. Furthermore, the first electromagnet 1605 maintains its attraction effect on the spline shaft. This provides axial support for the spline section of the spline shaft, counteracts the axial force applied by the milling cutter, avoids deformation due to stress, and ensures the quality of machining.

[0051] When the spline shaft is clamped in the center, the first lifting block 207 moves upward. Simultaneously, the rectangular tube 715, L-shaped rod 716, third sleeve rod 717, and third sleeve 718 drive the mounting cover 709 upward. At this time, the inclined surface 714 abuts against the rectangular block 705, pushing the triangular block 713 into the mounting cover 709. At the same time, the third spring 712 is compressed. Under the action of the limiting component, the rotating shaft 703 will not rotate. After each keyway of the spline is completed, the U-shaped plate 1604 is rotated downward and reset via the rotating mechanism, so that the U-shaped plate 1604 is in a vertically upward position. Then, When the first electromagnet 1605 is de-energized, the second lifting module 206 drives the first lifting block 207 to move downward a certain distance, causing the first electromagnet 1605 to disengage from the spline shaft. At the same time, when the first lifting block 207 moves downward, it can drive the mounting cover 709 to move downward. When the bottom of the triangular block 713 abuts against the rectangular block 705, it can push the rotating shaft 703 to rotate a certain angle. When the rotating shaft 703 rotates, it can drive the second gear 704 to rotate, thereby driving the V-shaped plate 505 to rotate along the second guide rail 504 through the second gear ring 701, which in turn drives the spline shaft to rotate a certain angle.

[0052] Meanwhile, when the rotating shaft 703 rotates, it drives the fixed ring 801 to rotate, causing the arc-shaped block 805 to slide from the arc-shaped groove 802 and along the side wall of the fixed ring 801. At the same time, the fourth spring 806 is compressed. When the arc-shaped block 805 slides into another arc-shaped groove 802, the arc-shaped block 805 can abut against the arc-shaped groove 802 under the action of the fourth spring 806. At this time, the rotating shaft 703 can be limited, making it more stable and reliable. This makes it easier to automatically rotate the spline shaft when milling splines, which is more convenient and faster, and can improve the processing efficiency.

[0053] During spline milling, the fifth spring 906 ensures that the polishing brush 905 abuts against the spline surface. Simultaneously, as the spline shaft rotates, the polishing brush 905 polishes the burrs on the spline surface. Furthermore, when the first lifting block 207 rises and falls, it drives the second mounting plate 1001 to rise and fall. At this time, the push pin 1004 rotates along the V-groove 1002 and drives the second sliding block 907 to reciprocate on the third guide rail 901 via the connecting bracket 1003, thereby driving the polishing brush 905 to reciprocate. This results in higher polishing efficiency and better effect, ensuring the quality of the milled spline.
