[0001] The invention belongs to the technical field of gear shaft spline processing, and specifically refers to a gear shaft spline grinding device. Background Art

[0002] The spline of a gear shaft is a raised part cut along the length of the shaft. It is usually located on the gear shaft and is used to connect the gear and the shaft. The main function of the spline is to connect the gear and the shaft to ensure a tight fit and stable transmission between them. Through the spline connection, the gear shaft can transfer power from one component to another. The processing of the gear shaft spline includes a variety of processing methods such as turning. There are burrs in the processed keyway, which needs to be further polished.

[0003] The existing gear shaft spline grinding device has the following problems: Since the number and length of the splines arranged on the outside of the gear shaft are not uniform, the existing method of grinding the gear shaft splines is mostly to grind them one by one, which takes a long time and has low grinding efficiency. It does not have the ability to synchronously grind multiple groups of splines on the outside of the gear shaft during the grinding operation. Therefore, it cannot meet the use requirements of the existing gear shaft spline grinding device, and there is an urgent need for a grinding device that can synchronously grind the gear shaft splines.

[0007] When in use, the gear shaft to be polished with the spline is placed between the anti-skid clamping plates, the clamping spring elastically extends to push the triangular block to slide along the inner wall of the positioning tube, the triangular block drives the positioning threaded rod to slide along the inner wall of the positioning tube to squeeze the gear shaft, the gear shaft is fixed between the anti-skid clamping plates, the positioning threaded rod is rotated away from one end of the anti-skid clamping plate, the positioning threaded rod rotates along the triangular block for relative movement, the positioning threaded rod drives the anti-skid clamping plate to increase the clamping force on the gear shaft; The sliding electromagnet generates magnetism when energized, and the driving magnet and the sliding electromagnet are set with the same pole.

When the locking magnet and the locking magnet are arranged relative to each other, the segment grinding plate stops sliding down along the segment opening, and the locking magnet is fixed inside the segment opening. Then the reversing motor drives the reversing frame to rotate through the power end, and the reversing frame drives the polished grinding block to flip over and approach the driving magnet. The thermoelectric refrigeration plate group uses the refrigeration end to cool the radiant copper plate. The temperature of the radiant copper plate is reduced to cool the grinding block after operation through cold radiation.

[0010] Specifically, a controller is provided on the upper wall of the grinding cylinder on one side of the current commutator.

[0011] Wherein, the controller is electrically connected to the clamping electromagnet, the current commutator, the commutation motor, the driving magnet and the thermoelectric cooling sheet group respectively.

[0012] Preferably, the model of the thermoelectric cooling chip group is TEC1-03104.

[0013] Furthermore, the model of the controller is HAD-SC200.

[0014] The beneficial effects achieved by adopting the above structure are as follows: Compared with the prior art, this solution adopts a combination of a segmented grinding structure and a reciprocating motion structure. Through the synchronous reciprocating mechanism and the radiation cooling mechanism, under the coordinated use of the positioning mechanism, the translation mechanism, the reversing mechanism, the segment grinding mechanism and the driving mechanism, on the one hand, through the multiple sets of grinding blocks, the corresponding grinding blocks can be driven into the spline for grinding according to the position of the spline on the side wall of the gear shaft. On the other hand, the number of grinding blocks entering the spline can be adjusted according to the length of the spline to ensure that the grinding blocks can be used for grinding during the grinding process. Splines of different lengths can be grinded synchronously and evenly to avoid the situation where longer splines cannot be partially grinded. In addition, with the combination of the reversing motor and the thermoelectric cooling plate group, the grinding block used for grinding can be cooled in advance, so that the spline grinding operation can be carried out at a low temperature. In addition, the sliding electromagnets arranged at both ends of the segment grinding plate can be cooled by the radiation copper plate to ensure that the magnetic field strength of the sliding electromagnet is not affected by the temperature generated by the grinding operation, so that the driving magnet can drive the grinding block to fit tightly inside the spline through the sliding electromagnet, thereby completing the spline grinding operation.

[0023] A controller 32 is disposed on the upper wall of the grinding cylinder 3 at one side of the current commutator 14 .

[0024] The controller 32 is electrically connected to the clamping electromagnet 12 , the current commutator 14 , the commutation motor 17 , the sliding electromagnet 28 and the thermoelectric cooling sheet group 31 , respectively.

[0025] The model of the thermoelectric cooling sheet group 31 is TEC1-03104.

[0026] The model of the controller 32 is HAD-SC200.

[0027] When in use, in the initial state, the clamping spring 8 is extended, the triangular block 7 drives the anti-skid cleat 10 to protrude from the inside of the positioning tube 6, and the gear shaft to be polished with splines is placed between the anti-skid cleats 10. The clamping spring 8 elastically extends to push the triangular block 7 to slide along the inner wall of the positioning tube 6, and the triangular block 7 drives the positioning threaded rod 9 to slide along the inner wall of the positioning tube 6. The positioning threaded rod 9 drives the anti-skid cleat 10 to fit the two sides of the gear shaft, and the gear shaft is fixed between the anti-skid cleats 10; The operator rotates the end of the positioning threaded rod 9 away from the anti-skid clamping plate 10, and the positioning threaded rod 9 rotates and moves relatively along the triangular block 7, and the positioning threaded rod 9 drives the anti-skid clamping plate 10 to increase the clamping force on the gear shaft; Since there are multiple sets of splines on the side wall of the gear shaft in the axial direction, it is necessary to push the grinding block 22 arranged vertically corresponding to the splines into the inside thereof to participate in the grinding operation; The controller 32 controls the sliding electromagnet 28 to start, and the driving magnet 27 is energized to generate magnetism. The driving magnet 27 and the sliding electromagnet 28 are arranged with the same pole. The driving magnet 27 is fixed on the driving seat 26 and pushes the sliding electromagnet 28 upward by repulsion. The sliding electromagnet 28 drives the segment grinding plate 21 to slide along the segment opening 20 through the limit block 23. The repulsion strength between the driving magnet 27 and the sliding electromagnet 28 is greater than the magnetic attraction between the locking magnet 24 and the locking magnet 33. The segment grinding plate 21 gets rid of the adsorption of the locking magnet 24 on the locking magnet 33, and the segment grinding plate 21 drives the grinding block 22 to enter the spline of the gear shaft; Since the lengths of the splines arranged on the side walls of the gear shafts are different, it is necessary to adjust the number of grinding blocks 22 entering the splines to ensure that the grinding blocks 22 can completely cover the inside of the splines under synchronous motion; When the length of the spline is relatively short, the grinding blocks 22 pushed into the spline are one group, and when the length of the spline is long, the grinding blocks 22 pushed into the spline are multiple groups, so that the length of the spline outside the filling grinding blocks 22 is consistent, and then under the drive of the clamping electromagnet 12 and the annular magnet 13, the grinding blocks 22 can grind the spline evenly; The controller 32 controls the clamping electromagnet 12 to start, and the clamping electromagnet 12 generates magnetism when it is energized. The clamping electromagnets 12 at both ends of the grinding cylinder 3 are set with different poles, and the magnetic fields at both ends of the grinding cylinder 3 are repulsive magnetic field and attractive magnetic field respectively. The clamping electromagnet 12 at one end of the grinding cylinder 3 is fixed on the inner wall of the positioning cylinder 6 and pushes the annular magnet 13 by repulsion. The annular magnet 13 drives the triangular block 7 to slide along the positioning cylinder 6 toward the end away from the clamping electromagnet 12. The triangular block 7 drives the gear axially to move the end of the grinding cylinder 3 with the attractive magnetic field through the positioning threaded rod 9. The clamping electromagnet 12 at the other end of the grinding cylinder 3 is fixed on the inner wall of the positioning cylinder 6 and absorbs the annular magnet 13 by magnetic force. The annular magnet 13 drives the triangular block 7 to slide along the positioning cylinder 6 toward the end close to the clamping electromagnet 12. The triangular block 7 drives the gear axially to move the end of the grinding cylinder 3 away from the repulsive magnetic field through the positioning threaded rod 9. The current commutator 14 controls the change of the direction of the current passing into the electromagnets 12 clamping at both ends of the grinding cylinder 3. The magnetic poles at both ends of the grinding cylinder 3 are interchanged, so that the gear shaft inside the grinding cylinder 3 moves in opposite directions. The gear shaft drives the spline groove and the grinding block 22 to rub against each other during the reciprocating motion. The grinding block 22 grinds the inner wall of the spline groove. There is a gap between the grinding blocks 22, so that the iron filings generated by the grinding inside the spline can be discharged, thereby ensuring the grinding quality of the spline. After the gear shaft spline is polished, the controller 32 controls the sliding electromagnet 28 to be powered off and demagnetized, and the magnetic field between the driving magnet 27 and the sliding electromagnet 28 disappears. The segment grinding plate 21 in the vertical direction slides down along the segment opening 20 under the action of the centripetal force, and the segment grinding plate 21 drives the locking magnet 24 to enter the segment opening 20. When the locking magnet 24 and the locking magnet 33 are arranged relative to each other, the segment grinding plate 21 stops sliding down along the segment opening 20, and the locking magnet 24 is fixed inside the segment opening 20. Then the controller 32 controls the reversing motor 17 to start, and the reversing motor 17 drives the reversing frame 18 to rotate through the power end, and the reversing frame 18 drives the polished grinding block 22 to flip and approach the driving magnet 27. The controller 32 controls the thermoelectric cooling plate group 31 to start, and the thermoelectric cooling plate group 31 uses the cooling end to cool the radiation copper plate 30. The temperature of the radiation copper plate 30 is reduced to cool the grinding block 22 after the operation through cold radiation. The grinding block 22 cooled by the radiation copper plate 30 is flipped to the side close to the grinding cylinder 3 to grind the gear shaft spline. The above operation can be repeated when it is used next time.
