Description

Technical Field

[0001] The invention relates to the technical field of automatic chamfering machines, in particular to a fully automatic chamfering device for producing rotor shafts. Background Art

[0002] Fully automatic chamfering machines have been widely used in the market. They are divided into two types: double-station and single-station. They are widely used in equipment manufacturing, mold manufacturing, hardware machinery, machine tool manufacturing, hydraulic parts and other fields. They are the development trend of the machinery industry.

[0003] The cutter disc turns and chamfers both ends of the steel shaft. The steel shaft may slip due to the high-speed rotation of the cutter disc. At this time, the cutter disc will transmit a spiral torque on the axis of the steel shaft, causing the steel shaft to spirally slide along the axis and hit the cutter disc on the other side, causing damage to the steel shaft and deviation in the chamfering accuracy. The flying iron chips generated during the turning of the steel shaft may cause injuries to workers. Summary of the invention

[0004] The object of the present invention is to provide a fully automatic chamfering device for producing a rotor shaft to solve the problems in the prior art.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a fully automatic chamfering device for rotor shaft production includes a box shell, a base frame, a hopper, a loading and unloading mechanism, a chamfering mechanism, a clamping mechanism and a chip cleaning mechanism. The base frame is fixedly connected to the box shell, the hopper, the loading and unloading mechanism, the chamfering mechanism and the clamping mechanism. The chamfering mechanism is rotatably connected to the clamping mechanism. Two groups of chamfering mechanisms and chip cleaning mechanisms are provided. The two groups of chamfering mechanisms and chip cleaning mechanisms are located on both sides of the clamping mechanism. The chip cleaning mechanism is fixedly connected to the clamping mechanism.

[0006] The chamfering device is used to perform chamfering processing on both ends of the rotor shaft. The pre-cut steel shaft body is loaded in the loading and unloading mechanism and fixed by the clamping mechanism. The chamfering mechanisms on both sides of the clamping mechanism are respectively pushed against the two ends of the steel shaft. The chamfering mechanism performs chamfering on both ends of the steel shaft. The steel shaft may slip due to the high-speed rotation of the chamfering mechanism. At this time, the chamfering mechanism on one side will transmit the spiral torque on the axis of the steel shaft, causing the steel shaft to spirally slip along the axis and hit the chamfering mechanism on the other side, causing damage to the steel shaft and deviation in the chamfering accuracy. The clamping mechanism can compensate for the polarization of the steel shaft caused by the rotation of the chamfering mechanism when fixing the steel shaft, thereby improving the accuracy of the chamfering. The chip cleaning mechanism can absorb the splashing iron chips generated by the steel shaft during turning, thereby avoiding injuries to workers caused by splashing iron chips and improving the recycling rate of iron chips. The steel shaft that has completed the chamfering is transported to the hopper by the loading and unloading mechanism.

[0007] Furthermore, the loading and unloading mechanism includes a mounting frame, a first cylinder, a ramp platform, a second cylinder, a transfer platform, a unloading track and a top plate. The bottom frame is fixedly connected to the mounting frame, the second cylinder, the unloading track, the transfer platform and the top plate. The first cylinder is fixedly connected to the mounting frame. A first through hole is provided on the top plate. The first through hole is slidingly connected to the output end of the first cylinder. The output end of the first cylinder is fixedly connected to the ramp platform. The ramp platform is in contact with the transfer platform, and the upper surface of the transfer platform is in contact with the output end of the second cylinder.

[0008] The pre-cut steel shaft slides down along the unloading track to the end of the transfer platform away from the hopper. The second cylinder pushes the steel shaft to the end of the transfer platform close to the hopper and is fixed by the clamping mechanism. After the chamfering is completed, the first cylinder pulls the ramp platform down, and the steel shaft slides down along the inclined surface of the ramp platform into the hopper.

[0009] Furthermore, the chamfering mechanism includes a side frame, a third cylinder, a first motor, a chamfering cutter disc, and a sliding rod. The side frame is fixedly connected to the base frame, the third cylinder, and the sliding rod. The output end of the third cylinder is fixedly connected to the first motor, the first motor is slidably connected to the sliding rod, the output end of the first motor is rotatably connected to the clamping mechanism, and the output end of the first motor is fixedly connected to the chamfering cutter disc.

[0010] The second cylinder pushes the steel shaft to the end on the transfer platform close to the hopper and is fixed by the clamping mechanism. The third cylinder pushes the first motor to slide along the sliding rod. The chamfering cutter disc contacts both ends of the steel shaft. The output torque of the first motor drives the chamfering cutter disc to rotate. As the third cylinder pushes the first motor close to the steel shaft, the chamfering cutter disc completes the turning and chamfering of the steel shaft.

[0011] Furthermore, the clamping mechanism includes a first gantry, a fourth cylinder, a connecting platform, a descending mechanism, a cross frame, a main arc shell and a compensation mechanism. The first gantry is fixedly connected to the base frame. The first gantry is provided with a top hole and a side hole.

The output end of the fourth cylinder is slidably connected to the top hole. The output end of the fourth cylinder is fixedly connected to the connecting platform. The connecting platform is slidably connected to the side wall of the first gantry. The descending mechanism is fixedly connected to the connecting platform. The cross frame is fixedly connected to the descending mechanism and the main arc shell. The main arc shell is provided with an arc rail. The descending mechanism is slidably connected to the arc rail. The compensation mechanism is fixedly connected to the main arc shell. The compensation mechanism is provided with several groups, and the several groups of compensation mechanisms are evenly distributed along the arc edge curve of the main arc shell. The first gantry is fixedly connected to the chip cleaning mechanism.

[0012] The second cylinder pushes the steel shaft to the end of the transfer platform close to the hopper, and the fourth cylinder pushes the connecting platform to slide down along the side wall of the first gantry. As the compensation mechanism evenly distributed along the arc edge curve of the main arc shell contacts the steel shaft, the fourth cylinder continues to push the connecting platform, and the descending mechanism clamps and fixes the steel shaft body. The compensation mechanism's own structure compensates for the polarization of the steel shaft caused by the rotation and turning of the chamfering mechanism.

[0013] Furthermore, the descending mechanism includes a second gantry, a first spring, a third gantry, a first gear, a first tooth head rod, a second tooth head rod and a side arc frame. The second gantry is fixedly connected to the connecting platform, the first spring is fixedly connected to the second gantry and the third gantry, the third gantry is slidably connected to the second gantry, the first gear and the second tooth head rod are rotatably connected to the third gantry, the second gantry is provided with a first tooth pair, the first tooth pair is meshed with the tooth surface of the first gear, the third gantry is provided with a second through hole, the second through hole is rotatably connected to the first tooth head rod, the first tooth head rod is meshed with the tooth surface of the first gear, the first tooth head rod is connected to the second tooth head rod through a belt drive, the side arc frame is provided with an arc tooth pair, the arc tooth pair is meshed with the tooth surface of the second tooth head rod, and the side arc frame is slidably connected to the arc rail.

[0014] The fourth cylinder continuously pushes the connecting platform, the side arc frame contacts the steel shaft and the third door frame is relatively fixed, and meshes with the tooth surface of the first gear through the first tooth pair on the side wall of the second door frame. The second door frame continuously slides down to drive the first gear to rotate, and the first gear transmits the torque to the second tooth head rod. The second tooth head rod is connected to the first tooth head rod through a belt drive, and the tooth surface of the second tooth head rod meshes with the arc tooth pair to transmit the torque to the side arc frame. The side arc frame rotates around the axis of the steel shaft along the arc track, and the steel shaft is fixed by a clamp formed by a compensation mechanism evenly distributed along the arc edge curve of the main arc shell and the deflected side arc frame.

[0015] Furthermore, the compensation mechanism includes a suction cup, a connecting plate, a first arc gantry, a second arc gantry, an arc column, a second spring and a torsion mechanism. The connecting plate is fixedly connected to the suction cup and the first arc gantry, the first arc gantry is slidably connected to the second arc gantry, the second arc gantry is fixedly connected to the main arc shell and the arc column, the second spring is fixedly connected to the top wall of the first arc gantry, the end of the second spring away from the first arc gantry is fixedly connected to the torsion mechanism, the torsion mechanism is fixedly connected to the first arc gantry, a slide groove is provided on the second arc gantry, the slide groove is slidably connected to the torsion mechanism, and the torsion mechanism is rotatably connected to the arc column and the second arc gantry.

[0016] When the steel shaft is about to deflect driven by the chamfering cutter disc, the suction cup adsorbed on the surface of the steel shaft drives the connecting plate to rotate around the axis of the steel shaft, and the first arc gantry slides along the arc side wall of the second arc gantry. The first arc gantry and the second arc gantry squeeze the second spring, and the second spring is compressed and deformed to recover the kinetic energy of the first arc gantry around the axis of the steel shaft, and the internal energy of the second spring is released. When the polarization amplitude of the steel shaft is larger, the first arc gantry is installed at one end of the first arc gantry and twisted with the torsion mechanism, and the angle of rotation of the first arc gantry around the axis of the steel shaft is larger, and the torsion mechanism twists the second spring to reduce the outer diameter of the second spring and increase the elastic stiffness of the second spring. That is, the larger the polarization amplitude of the steel shaft is, the less likely the second spring is to be compressed. Under the same deflection action of the first arc gantry, the compression degree of the second spring becomes smaller, and the deflection angle of the compensation steel shaft becomes smaller.

[0017] Furthermore, the torsion mechanism includes a ring platform, a second gear, a third gear and a fourth gantry. The ring platform is fixedly connected to an end of the second spring away from the first arc gantry, the ring platform is rotatably connected to the arc column, an internal gear ring groove is provided on the ring platform, the internal gear ring groove is meshed with the tooth surface of the second gear, the second gear is rotatably connected to the top wall of the second arc gantry, the third gear is rotatably connected to the side wall of the second arc gantry, the second gear is meshed with the tooth surface of the third gear, the fourth gantry is fixedly connected to the first arc gantry, the fourth gantry is slidably connected to the slide groove, a second gear pair is provided on the fourth gantry, and the second gear pair is meshed with the tooth surface of the third gear.

[0018] When the suction cup drives the connecting plate to rotate around the axis of the steel shaft, the first arc gantry approaches the second arc gantry, and the fourth gantry slides along the slide groove in the direction away from the connecting plate. The second tooth pair on the fourth gantry meshes with the tooth surface of the third gear, and the third gear meshes with the tooth surface of the second gear to transmit the torque to the ring table, which meshes with the tooth surface of the second gear through the internal gear ring groove on the ring table, driving the ring table to rotate around the arc column. One end of the second spring is fixed on the ring table, and the other end is fixed on the first arc gantry. As the ring table twists the second spring, the outer diameter of the second spring is reduced.

[0019] Furthermore, the chip cleaning mechanism includes a frame shell, a second motor, a third tooth head rod, an electromagnetic worm gear and a cylinder shell. The frame shell is fixedly connected to the first door frame, the second motor and the cylinder shell. The third tooth head rod, the electromagnetic worm gear and the cylinder shell are each provided with two groups. The two groups of the third tooth head rod, the electromagnetic worm gear and the cylinder shell are respectively arranged at two ends of the frame shell. The two groups of the third tooth head rod are connected to the output end of the second motor through a belt drive. The third tooth head rod is meshed with the tooth surface of the electromagnetic worm gear, and the electromagnetic worm gear is rotationally connected to the cylinder shell.

[0020] When the chamfering cutter disc is chamfering the steel shaft, the second motor outputs torque to the third tooth head rod through the belt, and the third tooth head rod transmits torque to the electromagnetic worm through tooth surface engagement. The electromagnetic worm rotates around the axis of the cylinder shell, and the magnetic field eddy current generated by the rotation absorbs the flying iron chips through the four groups of electromagnetic worms respectively arranged on both sides of the two groups of chamfering cutters.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention designs a descending mechanism, and the fourth cylinder continuously pushes the connecting platform side arc frame to contact the steel shaft, and the third door frame is relatively fixed, and the first tooth pair is meshed with the first gear tooth surface, driving the first gear to rotate and transmit torque to the second tooth head rod, and the second gear head rod tooth surface meshes with the arc tooth pair to transmit torque to the side arc frame, and the side arc frame rotates around the axis of the steel shaft along the arc track to form a clamp to fix the steel shaft; the present invention designs a compensation mechanism, when the steel shaft deflects under the drive of the chamfering cutter disc, the suction cup drives the connecting plate to rotate around the axis of the steel shaft, and the first arc door frame slides along the arc side wall of the second arc door frame, squeezing the second spring to compress and restore the deformation, converting kinetic energy into the internal energy of the second spring for release, and when the polarization amplitude generated by the steel shaft is larger, the fourth door frame slides along the slide groove in the direction away from the connecting plate, the second tooth pair is meshed with the third gear tooth surface, and the third gear is meshed with the second gear tooth surface The meshing transmission torque is transmitted to the ring table, and the meshing of the tooth surface of the inner ring groove on the ring table drives the ring table to rotate around the arc column. As the ring table twists the second spring, the outer diameter of the second spring is reduced, and the outer diameter of the second spring is reduced, and the elastic stiffness of the second spring is increased. That is, the greater the polarization amplitude generated by the steel shaft, the less likely the second spring is to be compressed. Under the same deflection force of the first arc gantry, the compression degree of the second spring becomes smaller, and the deflection angle of the compensation steel shaft becomes smaller; the present invention can automatically load and unload materials to complete the turning and chamfering of both ends of the pre-cut steel shaft, and compensate for the polarization of the steel shaft caused by the rotating turning of the chamfering cutter disc, so as to avoid the steel shaft from spirally sliding along the axis and hitting the chamfering cutter disc on the other side, causing damage to the steel shaft and deviation in the chamfering accuracy, thereby improving the accuracy of turning and chamfering, absorbing the splashing iron chips generated by the steel shaft during turning, avoiding the splashing of iron chips and causing injuries to workers, and improving the recycling rate of iron chips.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] like Figure 1 As shown, the present invention provides a technical solution of a fully automatic chamfering device for rotor shaft production, including a box shell 1, a base frame 2, a hopper 3, a loading and unloading mechanism 4, a chamfering mechanism 5, a clamping mechanism 6 and a chip cleaning mechanism 7. The base frame 2 is fixedly connected to the box shell 1, the hopper 3, the loading and unloading mechanism 4, the chamfering mechanism 5 and the clamping mechanism 6. The chamfering mechanism 5 is rotatably connected to the clamping mechanism 6. Two groups of chamfering mechanisms 5 and chip cleaning mechanisms 7 are provided. The two groups of chamfering mechanisms 5 and chip cleaning mechanisms 7 are located on both sides of the clamping mechanism 6. The chip cleaning mechanism 7 is fixedly connected to the clamping mechanism 6.

[0026] The chamfering device is used to perform chamfering on both ends of the rotor shaft. The pre-cut steel shaft body is loaded in the loading and unloading mechanism 4 and fixed by the clamping mechanism 6. The chamfering mechanisms 5 on both sides of the clamping mechanism 6 are respectively pushed against the two ends of the steel shaft. The chamfering mechanism 5 performs chamfering on the two ends of the steel shaft. The steel shaft may slip due to the high-speed rotation of the chamfering mechanism 5. At this time, the chamfering mechanism 5 on one side will transmit the spiral torque on the axis of the steel shaft, causing the steel shaft to spirally slip along the axis and hit the chamfering mechanism 5 on the other side, causing damage to the steel shaft and deviation in the chamfering accuracy. The clamping mechanism 6 compensates for the polarization of the steel shaft caused by the rotation of the chamfering mechanism 5 when fixing the steel shaft, thereby improving the accuracy of the chamfering. The chip cleaning mechanism 7 can absorb the splashing iron chips generated by the steel shaft during turning, thereby avoiding injuries to workers caused by splashing iron chips and improving the recycling rate of iron chips. The steel shaft that has completed the chamfering is transported to the hopper 3 by the loading and unloading mechanism 4.

[0028] The pre-cut steel shaft slides down along the unloading track 46 to the end of the transfer platform 45 away from the hopper 3, and the second cylinder 44 pushes the steel shaft to the end of the transfer platform 45 close to the hopper 3 to be fixed by the clamping mechanism 6. After the chamfering is completed, the first cylinder 42 pulls the ramp platform 43 down, and the steel shaft slides down along the inclined surface of the ramp platform 43 into the hopper 3.

[0029] like Figure 3 As shown, the chamfering mechanism 5 includes a side frame 51, a third cylinder 52, a first motor 53, a chamfering cutter disc 54, and a sliding rod 55. The side frame 51 is fixedly connected to the base frame 2, the third cylinder 52, and the sliding rod 55. The output end of the third cylinder 52 is fixedly connected to the first motor 53, the first motor 53 is slidably connected to the sliding rod 55, the output end of the first motor 53 is rotationally connected to the clamping mechanism 6, and the output end of the first motor 53 is fixedly connected to the chamfering cutter disc 54.

[0030] The second cylinder 44 pushes the steel shaft to the transfer platform 45, where one end is close to the hopper 3 and is fixed by the clamping mechanism 6. The third cylinder 52 pushes the first motor 53 to slide along the slide rod 55. The chamfering cutter disc 54 contacts both ends of the steel shaft. The first motor 53 outputs a torque to drive the chamfering cutter disc 54 to rotate. As the third cylinder 52 pushes the first motor 53 close to the steel shaft, the chamfering cutter disc 54 completes the turning and chamfering of the steel shaft.

[0031] like Figure 3 , Figure 4 , Figure 5 As shown, the clamping mechanism 6 includes a first gantry 61, a fourth cylinder 62, a connecting platform 63, a descending mechanism 64, a cross frame 65, a main arc shell 66 and a compensation mechanism 67.

The two groups of side holes 612 are respectively provided on the two side walls of the first gantry 61. The side hole 612 is rotatably connected to the output end of the first motor 53. The fourth cylinder 62 is fixedly connected to the first gantry 61. The output end of the fourth cylinder 62 is slidably connected to the top hole 611. Then, the output end of the fourth cylinder 62 is fixedly connected to the connecting platform 63, the connecting platform 63 is slidably connected to the side wall of the first gantry 61, the descending mechanism 64 is fixedly connected to the connecting platform 63, the cross frame 65 is fixedly connected to the descending mechanism 64 and the main arc shell 66, the main arc shell 66 is provided with an arc track 661, the descending mechanism 64 is slidably connected to the arc track 661, the compensation mechanism 67 is fixedly connected to the main arc shell 66, the compensation mechanism 67 is provided with several groups, and the several groups of compensation mechanisms 67 are evenly distributed along the arc edge curve of the main arc shell 66, and the first gantry 61 is fixedly connected to the chip cleaning mechanism 7.

[0032] The second cylinder 44 pushes the steel shaft to one end of the transfer platform 45 close to the hopper 3, and the fourth cylinder 62 pushes the connecting platform 63 to slide down along the side wall of the first gantry 61. As the compensation mechanism 67 evenly distributed along the arc edge curve of the main arc shell 66 contacts the steel shaft, the fourth cylinder 62 continues to push the connecting platform 63, and the descending mechanism 64 clamps and fixes the steel shaft body, and the polarization of the steel shaft caused by the rotation turning of the chamfering mechanism 5 is compensated through the structure of the compensation mechanism 67 itself.

[0033] like Figure 4 , Figure 5As shown, the descending mechanism 64 includes a second door frame 641, a first spring 642, a third door frame 643, a first gear 644, a first tooth head rod 645, a second tooth head rod 646 and a side arc frame 647. The second door frame 641 is fixedly connected to the connecting platform 63, the first spring 642 is fixedly connected to the second door frame 641 and the third door frame 643, the third door frame 643 is slidably connected to the second door frame 641, the first gear 644 and the second tooth head rod 646 are both rotatably connected to the third door frame 643, and the second door frame 641 is provided with a There is a first tooth pair 6411, the first tooth pair 6411 is meshed with the tooth surface of the first gear 644, the third door frame 643 is provided with a second through hole 6431, the second through hole 6431 is rotatably connected to the first tooth head rod 645, the first tooth head rod 645 is meshed with the tooth surface of the first gear 644, the first tooth head rod 645 is connected to the second tooth head rod 646 through a belt drive, the side arc frame 647 is provided with an arc tooth pair 6471, the arc tooth pair 6471 is meshed with the tooth surface of the second tooth head rod 646, and the side arc frame 647 is slidably connected to the arc rail 661.

[0034] The fourth cylinder 62 continuously pushes the connecting platform 63, and the side arc frame 647 contacts the third door frame 643 of the steel shaft and is relatively fixed. It meshes with the tooth surface of the first gear 644 through the first tooth pair 6411 on the side wall of the second door frame 641. The second door frame 641 continues to slide down to drive the first gear 644 to rotate. The first gear 644 transmits torque to the second tooth head rod 646. The second tooth head rod 646 is connected to the first tooth head rod 645 through a belt drive. The tooth surface of the second tooth head rod 646 meshes with the arc tooth pair 6471 to transmit torque to the side arc frame 647. The side arc frame 647 rotates around the axis of the steel shaft along the arc track 661, and the steel shaft is fixed by a clamp formed by the compensation mechanism 67 evenly distributed along the arc edge curve of the main arc shell 66 and the deflected side arc frame 647.

[0035] like Figure 6 , Figure 7 As shown, the compensation mechanism 67 includes a suction cup 671, a connecting plate 672, a first arc gantry 673, a second arc gantry 674, an arc column 675, a second spring 676 and a torsion mechanism 677. The connecting plate 672 is fixedly connected to the suction cup 671 and the first arc gantry 673. The first arc gantry 673 is slidably connected to the second arc gantry 674. The second arc gantry 674 is fixedly connected to the main arc shell 66 and the arc column 675. The second spring 676 is fixedly connected to the top wall of the first arc gantry 673. The end of the second spring 676 away from the first arc gantry 673 is fixedly connected to the torsion mechanism 677. The torsion mechanism 677 is fixedly connected to the first arc gantry 673. A slide groove 6741 is provided on the second arc gantry 674. The slide groove 6741 is slidably connected to the torsion mechanism 677. The torsion mechanism 677 is rotationally connected to the arc column 675 and the second arc gantry 674.

[0036] When the steel shaft is about to deflect under the drive of the chamfering cutter disc 54, the suction cup 671 adsorbed on the surface of the steel shaft drives the connecting plate 672 to rotate around the axis of the steel shaft, and the first arc gantry 673 slides along the arc side wall of the second arc gantry 674. The first arc gantry 673 and the second arc gantry 674 squeeze the second spring 676, and the second spring 676 is compressed and restored to deform, and the kinetic energy of the first arc gantry 673 rotating around the axis of the steel shaft is converted into the internal energy of the second spring 676 for release. When the polarization amplitude of the steel shaft is larger, By being installed at one end of the first arc gantry 673 and twisting with the torsion mechanism 677, the greater the angle of rotation of the first arc gantry 673 around the axis of the steel shaft, the more the torsion mechanism 677 twists the second spring 676, thereby reducing the outer diameter of the second spring 676 and increasing the elastic stiffness of the second spring 676. That is, the greater the polarization amplitude produced by the steel shaft, the less likely the second spring 676 is to be compressed. Under the same deflection action of the first arc gantry 673, the compression degree of the second spring 676 becomes smaller, compensating for the smaller deflection angle of the steel shaft.

[0037] like Figure 7 As shown, the torsion mechanism 677 includes a ring platform 6771, a second gear 6772, a third gear 6773 and a fourth portal 6774. The ring platform 6771 is fixedly connected to one end of the second spring 676 away from the first arc portal 673, the ring platform 6771 is rotatably connected to the arc column 675, an inner gear ring groove 67711 is provided on the ring platform 6771, the inner gear ring groove 67711 is meshed with the tooth surface of the second gear 6772, the second gear 6772 is rotatably connected to the top wall of the second arc portal 674, the third gear 6773 is rotatably connected to the side wall of the second arc portal 674, the second gear 6772 is meshed with the tooth surface of the third gear 6773, the fourth portal 6774 is fixedly connected to the first arc portal 673, the fourth portal 6774 is slidably connected to the slide groove 6741, and a second gear pair 67741 is provided on the fourth portal 6774, and the second gear pair 67741 is meshed with the tooth surface of the third gear 6773.

[0038] When the suction cup 671 drives the connecting plate 672 to rotate around the axis of the steel shaft, the first arc gantry 673 approaches the second arc gantry 674, and the fourth gantry 6774 slides along the slide groove 6741 in the direction away from the connecting plate 672, and the second tooth pair 67741 on the fourth gantry 6774 meshes with the tooth surface of the third gear 6773, and the third gear 6773 meshes with the tooth surface of the second gear 6772 to transmit the torque to the ring platform 6771, which meshes with the tooth surface of the second gear 6772 through the internal tooth ring groove 67711 on the ring platform 6771, thereby driving the ring platform 6771 to rotate around the arc column 675, and one end of the second spring 676 is fixed on the ring platform 6771, and the other end is fixed on the first arc gantry 673. As the ring platform 6771 twists the second spring 676, the outer diameter of the second spring 676 is reduced.

[0039] like Figure 8As shown, the chip cleaning mechanism 7 includes a frame shell 71, a second motor 72, a third tooth head rod 73, an electromagnetic worm 74 and a cylinder shell 75. The frame shell 71 is fixedly connected to the first door frame 61, the second motor 72 and the cylinder shell 75. The third tooth head rod 73, the electromagnetic worm 74 and the cylinder shell 75 are each provided with two groups. The two groups of the third tooth head rod 73, the electromagnetic worm 74 and the cylinder shell 75 are respectively arranged at both ends of the frame shell 71. The two groups of the third tooth head rod 73 are connected to the output end of the second motor 72 through a belt drive. The third tooth head rod 73 is meshed with the tooth surface of the electromagnetic worm 74, and the electromagnetic worm 74 is rotationally connected to the cylinder shell 75.

[0040] When the chamfering cutter disc 54 chamfers the steel shaft, the second motor 72 outputs torque to the third tooth head rod 73 through the belt, and the third tooth head rod 73 transmits torque to the electromagnetic worm 74 through tooth surface engagement. The electromagnetic worm 74 rotates around the axis of the cylinder shell 75. Through the four groups of electromagnetic worms 74 respectively arranged on both sides of the two groups of chamfering cutter discs 54, the magnetic field eddy current generated by the rotation absorbs the flying iron chips.

[0041] The working principle of the present invention is as follows: the steel shaft slides down along the unloading track 46 to the end of the transfer platform 45 away from the hopper 3, the second cylinder 44 pushes the steel shaft to the end close to the hopper 3, the fourth cylinder 62 pushes the connecting platform 63 down, the compensation mechanism 67 and the side arc frame 647 contact the steel shaft, and the first gear 644 is meshed with the tooth surface through the first gear pair 6411, the second door frame 641 continues to slide down to drive the first gear 644 to rotate, and the torque is transmitted to the second gear head rod 646, and the second gear head rod 646 and the first gear head rod 64 The side arc frame 647 is connected by belt transmission, and the torque is transmitted to the side arc frame 647 through the tooth surface meshing arc gear pair 6471. The side arc frame 647 rotates around the axis of the steel shaft along the arc track 661 to form a clamp to fix the steel shaft. The chamfering cutter head 54 contacts both ends of the steel shaft to complete the turning chamfering of the steel shaft. When the steel shaft is about to deflect under the drive of the chamfering cutter head 54, the suction cup 671 adsorbed on the surface of the steel shaft drives the connecting plate 672 to rotate around the axis of the steel shaft, and the first arc gantry 673 slides and squeezes along the arc side wall of the second arc gantry 674. The second spring 676, the compression recovery deformation of the second spring 676, converts the kinetic energy of the first arc gantry 673 rotating around the axis of the steel shaft into the internal energy release of the second spring 676. When the polarization amplitude generated by the steel shaft is larger, the fourth gantry 6774 slides along the slide groove 6741 in the direction away from the connecting plate 672, and the second gear pair 67741 on the fourth gantry 6774 meshes with the tooth surface of the third gear 6773, transmitting torque to the ring table 6771, driving the ring table 6771 to rotate around the arc column 675. The ring platform 6771 twists the second spring 676 to reduce the outer diameter of the second spring 676 and increase the elastic stiffness of the second spring 676. That is, the greater the polarization amplitude generated by the steel shaft, the less likely the second spring 676 is to be compressed. Under the same deflection action of the first arc gantry 673, the compression degree of the second spring 676 becomes smaller, compensating for the smaller deflection angle of the steel shaft. The four sets of electromagnetic worm gears 74 rotate to generate eddy currents in the magnetic field that absorb the flying iron chips, and the steel shaft slides down along the inclined surface of the ramp platform 43 into the hopper 3.
