The specific implementation process is as follows:
initially, the controller controls the oil pressure system to supply hydraulic oil to the oil pressure sleeve 35 and the alignment sleeve, and the hydraulic oil in the oil pressure sleeve 35 enters from the first oil inlet 32, so that the first thimble 31 extends into the oil pressure sleeve 35 and presses the first spring 33. The hydraulic oil in the alignment sleeve enters from the oil inlet, so that the third ejector pin 41 extends into the alignment sleeve and presses the third spring 42.
Then, the fan gear 21 is hoisted between the first thimble 31 and the second thimble 17 and placed on the support seat 51, in this embodiment, a hole is formed in the fan gear 21, the controller is turned on, the controller controls the oil pressure system to send hydraulic oil to the second oil inlet 34, the hydraulic oil extrudes the first thimble 31, the first thimble 31 pushes the fan gear 21 to move towards the second thimble 17, and the right end surface of the fan gear 21 abuts against the second thimble 17, so that the second thimble 17 slides towards the right side, meanwhile, the right end surface of the fan gear 21 abuts against the ball 24, and the clamping plate 22 is pushed to rotate, so that the buckle 23 clamps the fan gear 21. The second ejector pin 17 slides to a certain distance, the first sensor acquires the movement information of the second ejector pin 17, the controller determines whether the movement distance of the second ejector pin 17 reaches a preset value or not based on the movement information, when the movement distance of the second ejector pin 17 does not reach the preset value, the controller sends an alarm working signal to the alarm, and the alarm gives an alarm to inform an operator that the length of the fan gear 21 is in a problem.
When the moving distance of the second thimble 17 reaches the preset value, the controller controls the oil pressure system to stop sending the hydraulic oil to the oil pressure sleeve 35, and controls the oil pressure system to withdraw the hydraulic oil in the alignment sleeve, and under the action of the third spring 42, the third thimble 41 abuts against the left end face of the fan gear 21. When the third thimble 41 moves a certain distance, the second sensor obtains the distance information of the third thimble 41, and the controller controls the servo motor 11 to operate for the first time based on the distance information. The servo motor 11 drives the main gear 12 and the driven gear 13 to rotate so as to drive the ejector pin sleeve 18 and the clamp to rotate, the clamp drives the fan gear 21 to rotate, when the third ejector pin 41 is aligned with the hole on the fan gear 21, the third ejector pin 41 can extend into the hole of the fan gear 21, at this time, the third ejector pin 41 can extrude the fan gear 21 so as to enable the fan gear 21 to move for a certain distance, and the purpose of alignment is achieved, of course, when the third ejector pin 41 extends into the hole of the fan gear 21 and does not extrude the fan gear 21, the fan gear 21 is aligned during clamping. The third thimble 41 has been shown to be aligned when it extends into the aperture of the fan gear 21.
When the third thimble 41 stretches into the hole of the fan gear 21, the third thimble 41 moves a certain distance again, the second sensor sends the distance information of the third thimble 41 to the controller, and the controller controls the oil pressure system to send hydraulic oil into the alignment sleeve again, so that the third thimble 41 stretches into the alignment sleeve again. At this time, the controller will control the servo motor 11 to work for the second time, the servo motor 11 drives the thimble sleeve 18 to rotate a certain angle through the main gear 12 and the slave gear 13, and then the blower gear 21 rotates a certain angle, the controller controls the saw teeth 71 of the band saw machine to perform tooth punching on the blower gear 21, and within a certain time, the controller will control the saw teeth 71 to reset, and the servo motor 11 drives the blower gear 21 to rotate a certain angle again.
In this embodiment, the process of machining the teeth of the fan gear 21 is as follows: for example: twenty teeth are processed on the fan gear 21, one side of the twenty teeth is processed in advance, after one side of the twenty teeth is processed, the controller can control the motor 64 to work, the motor 64 can drive the ball screw 65 to work, the ball screw 65 drives the base to slide for a certain distance, the fan gear 21 moves for a certain distance, after the radial position of the fan gear 21 is adjusted, the controller can control the saw teeth 71 and the servo motor 11 to work, and the other side of the twenty teeth is processed. In this embodiment, after one side of the plurality of teeth is processed, the bottom plate 61 is adjusted, the number of times of adjusting the bottom plate 61 is greatly reduced, the number of times of reciprocating motion of the servo motor 11 is greatly reduced, and energy consumption is reduced.
In this embodiment, the nut 14 rotates in the thimble sleeve 18, the nut 14 may press the second spring 16 to adjust the distance of the second thimble 17, and meanwhile, the acting force of the second spring 16 may enable the second thimble 17 to tightly press the fan gear 21. When the servo motor 11 drives the master gear 12 and the slave gear 13 to rotate, a certain distance is formed between the master gear 12 and the slave gear 13, which easily causes the slave gear 13 and the ejector pin sleeve 18 to rotate, and further causes an error in the rotation angle of the fan gear 21, the slave gear 13 is extruded by the fourth spring 15, so that the frictional resistance of the slave gear 13 is increased, the rotation probability of the slave gear 13 and the ejector pin sleeve 18 is reduced, the fan gear 21 cannot rotate, and the accuracy of adjusting the angle of the fan gear 21 is improved. After the fan gear 21 is processed, the hydraulic system draws away the hydraulic oil in the hydraulic sleeve 35, and the first spring 33 abuts against the first thimble 31 to prevent the fan gear 21 from falling.
In this embodiment, owing to carried out the preliminary fluting processing of fan gear tooth, and then when utilizing the gear hobbing machine to add man-hour to the fan gear, the machining allowance of tooth is few, can adopt miniature gear hobbing machine (large-scale gear hobbing machine cost is high up to a million, and the gear hobbing machine only needs tens of thousands carefully), has reduced the processing cost of fan gear, simultaneously, because the machining allowance of fan gear tooth is few, has improved the machining efficiency of gear hobbing machine and the machining precision of fan gear.
