Detailed Embodiments

[0008] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0009] As shown in Figures 1 to 3As shown in the figure, an alternator lead correction device includes: a first lifting mechanism, and also includes: A lead correction mechanism, which is located directly above the first lifting mechanism; The lead correction mechanism includes a correction drive assembly and a correction assembly. The correction drive assembly is located above the correction assembly; The correction assembly includes a counterbore sleeve 1, an outer shield 2, a flange 3, a pressure sensor 4, a lower connecting plate 5, a lower connecting shaft 6, and a calibration detection frame 7. The flange 3 is connected to the upper end face of the lower connecting plate 5. The pressure sensor 4 is installed on the flange 3. The outer shield 2 is sleeved on the counterbore sleeve 1, and the outer shield 2 is also connected to the upper end face of the lower connecting plate 5. The flange 3 and the pressure sensor 4 are located inside the outer shield 2. One end of the counterbore sleeve 1 is matched with the correction drive assembly, and the other end of the counterbore sleeve 1 is matched with the pressure sensor 4. The lower connecting shaft 6 is connected to the lower end face of the lower connecting plate 5, and the calibration detection frame 7 is connected to the lower connecting shaft 6. The calibration detection frame 7 includes a body 7-1 and several heads 7-2. These heads 7-2 are arranged radially along the body 7-1. A lead correction tube 8 and a position sensor 9 are installed on each head 7-2. The mouth of the lead correction tube 8 is in a flared shape, and the mouth of the lead correction tube 8 is vertically downward.

[0010] In this implementation, when the alternator lead is corrected, the correction drive assembly pushes the correction assembly downward, and the alternator lead is inserted into the lead correction tube 8. Since the lead correction tube 8 is in a vertical state, the lead will also be straightened under the restraint of the lead correction tube 8, thus achieving the correction effect. Among them, the mouth of the lead correction tube 8 is in a flared shape (as Figure 7 shown), this structure can prevent the lead from not being inserted into the lead correction tube 8 because the skew angle of each lead is different.

[0011] A radial notch 8-1 is provided on the radial wall surface of the lead correction tube 8, and at least a part of the position sensor 9 is inserted into the radial notch 8-1.

[0012] In this implementation, when the lead is inserted into the lead correction tube 8, if the position sensor 9 does not sense the sensor, it means that the insertion depth of the lead is insufficient. According to Figures 1 to 3 shown, in this implementation, there are four lead correction tubes 8, and four position sensors 9 are also provided, and the heights of the four position sensors 9 are the same. Therefore, after the four leads are simultaneously inserted into the lead correction tubes 8, all four position sensors 9 must sense the leads before the correction is completed.

[0013] The correction driving assembly includes a lowering driver 10, an upper connecting plate 11, a first guide rod 12, a second guide rod 13, a first guide sleeve 14, and a second guide sleeve 15. The lowering driver 10 is installed on the upper end surface of the upper connecting plate 11. The output end of the lowering driver 10 passes through the upper connecting plate 11 and is engaged with the counterbore sleeve 1. The first guide sleeve 14 and the second guide sleeve 15 are respectively installed on the upper end surface of the upper connecting plate 11. The first guide rod 12 and the second guide rod 13 are respectively connected to the upper end surface of the lower connecting plate 5, and the first guide rod 12 is movably engaged with the first guide sleeve 14, and the second guide rod 13 is movably engaged with the second guide sleeve 15.

[0014] The first jacking mechanism includes: a jack 20; A jacking plate 21, the lower end surface of which is connected to the output end of the jack 20; A plurality of jacking auxiliary components 22, one end of which is connected to the lower end surface of the jacking plate 21; A bottom plate 23, the other end of the jacking auxiliary component 22 is connected to the bottom plate 23, and the jack 20 is installed on the bottom plate 23.

[0015] The diameter of the flared mouth of the lead correction tube 8 is ≥12 mm, and the axial aperture of the lead correction tube 8 is ≥1.8 mm.

[0016] The working principle of the present invention is as follows: The alternator that needs to correct the lead is placed on the jacking plate 21. The jack 20 jacks up the jacking plate 21 upward, and at the same time the jacking auxiliary components 22 rise. After reaching the highest position, the output end of the lowering driver 10 is inserted into the counterbore of the counterbore sleeve 1 and continuously applies downward pressure. The lower connecting plate 5 receives a downward thrust. The lower connecting plate 5 moves vertically downward under the guiding action of the first guide rod 12, the second guide rod 13, the first guide sleeve 14, and the second guide sleeve 15. Then the mouth of the lead correction tube 8 contacts the lead. As the lead correction tube 8 continues to move downward, the lead is inserted into the tube of the lead correction tube 8, and the position sensor 9 senses the lead. The first jacking mechanism resets, and the correction driving assembly and the correction assembly reset, and finally the lead correction is completed.

[0017] Such as Figures 4 to 6As shown, in this embodiment, the AC generator lead wire correction device is a set of auxiliary assembly devices in the AC generator rear cover assembly equipment. When the entire assembly equipment assembles the rear cover of the AC generator, first, the tray B (the tray B is provided with a pulley placement area B-1, a rotor placement area B-2, a wave pad placement area B-3, a rear cover placement area B-4, an AC generator shell placement area B-6, and a main placement area B-5) containing the AC generator parts is placed above the first lifting mechanism through the conveying mechanism A, wherein the pulley, the rotor, and the AC generator shell have been assembled in the upstream process and placed on the main placement area B-5. When the tray B arrives above the first lifting mechanism, the sensors arranged on both sides of the conveying mechanism A sense whether there are products on the tray B. If there are no products, the empty tray B is released. If there are products, the wave pad grabbing and placing mechanism D grabs the wave pad C placed in the wave pad placement area B-3 and places it on the rotor shaft. Then the lead wire correction mechanism performs the lead wire X correction according to the above steps. When the lowering driver 10 applies force downward, the pressure sensor 4 will lower the driver The pressure applied by 10 is fed back to the control program of the whole equipment, and the control program is used to control the force applied downward by the descending driver 10 to avoid excessive force from damaging or deforming the wave pad. After the lead-out line X is corrected, the conveying mechanism A conveys the pallet B to the second lifting mechanism L, and the second lifting mechanism L lifts the pallet B. The wave pad correction mechanism F of the second power unit E corrects the wave pad C on the rotor shaft to ensure that the wave pad C does not interfere with the rear cover during assembly. After the wave pad C is corrected, the rear cover of the second power unit E is grabbed. Mechanism G grabs the rear cover from the rear cover placement area B-4 of tray B and places it on the AC generator housing. At this time, the four lead wires X of the AC generator can successfully pass through the four holes of the rear cover (as shown in the attached figure) because the four lead wires X have been corrected. After the rear cover is installed, the rear cover is pressed by the rear cover clamping mechanism H. At this point, the installation of the rear cover of the AC generator and the correction of the lead wires X are completed. The conveying mechanism A then conveys the tray B and the AC generator downstream, and the bolts are installed and tightened in the subsequent process.
