[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The generator stator rotor gap measuring device can achieve the purpose of convenient adjustment, detection and automatic marking through the coordinated use of the second piston, push plate, adjustment plate, movable plate, third piston, unqualified stamp, qualified stamp, movable plate, seventh piston, laser transmitter and laser receiver. Before using the device, the positions of the two adjustment plates can be adjusted according to the standard gap range of the generator stator rotor, and then the two adjustment plates can be fixed. The movable plate moves downward to drive the three seventh pistons to move downward, and the laser transmitter and laser receiver move downward synchronously. At first, the laser receiver cannot receive the laser emitted by the laser transmitter. When the laser emitted by the laser transmitter is shot at When the laser receiver is between the stator and the rotor, it can receive the laser emitted by the laser transmitter. When the laser receiver cannot receive the laser emitted by the laser transmitter again, the second piston and the push plate automatically move to the right. If the push plate can push the upper adjustment plate to the right, it means that the gap between the stator and the rotor is too small. If the push plate can push the lower adjustment plate to the right, it means that the gap between the stator and the rotor is too large. If any adjustment plate moves to the right, it will push the movable plate and the third piston to move to the right. At this time, the unqualified seal moves down and stamps on the stator. If the push plate moves between the two adjustment plates, it means that the gap between the stator and the rotor is within the standard range. The qualified seal moves down and stamps on the stator, which facilitates the effect of automatic marking.

[0016] 2. The generator stator-rotor gap measuring device can achieve the purpose of clamping and fixing by using the provided clamping plates and the clamping sleeves in coordination with each other. The two clamping plates can be used to clamp and fix the stator, and the two clamping sleeves can be used to clamp and fix the bearings on the rotor. Then, the stator can be energized, the rotor rotates automatically, and then the stator-rotor gap can be measured.

[0017] 3. The generator stator-rotor gap measuring device can achieve the purpose of hydraulic diversion through the coordinated use of the second oil cylinder, push plate, extrusion rod, slide rail, adjustment plate, fourth oil cylinder, qualified seal, fifth oil cylinder, valve plate, connecting column and movable block. When the stator-rotor gap is not within the standard range, the push plate will push one of the adjustment plates to the right, and the slide rail and the extrusion rod will move right accordingly. The extrusion rod releases the extrusion of the movable block, and the movable block, the connecting column and the valve plate automatically pop up, and the hydraulic oil pressed from the second oil cylinder to the fourth oil cylinder will enter the fifth oil cylinder, and the qualified seal will not contact the stator.

The two adjustment plates 90 89 can slide up and down. Before using the device, the positions of the two adjusting plates 9089 can be adjusted according to the standard gap range of the generator stator and rotor. After determining the position of the adjusting plates 9089, the fasteners 90810 can be tightened to fix the adjusting plates 9089.

[0037] The use method and advantages of the present invention: The working process of the generator stator rotor gap measuring device is as follows:

[0038] like Figures 1 to 7 As shown: first, move the two adjustment plates 9089 up and down to adjust the height of the two adjustment plates 9089 according to the standard gap range of the generator stator rotor. After the adjustment operation is completed, use the fasteners 90810 to tighten and fix the two adjustment plates 9089. First, place the stator between the two clamping plates 6, extend the first electric telescopic column 2 and the second electric telescopic column 4, and the two clamping plates 6 are close to each other to clamp and fix the stator. After the rotor is inserted into the stator, the two third electric telescopic columns 7 are extended, and the two jackets 8 are close to each other to clamp and fix the bearings on the rotor. After the stator is energized, the rotor rotates, and the moving plate 12 and the three The seventh piston 13 moves down as a whole, the two eighth pistons 18 move down, the first piston 903, the second piston 905, the second oil cylinder 906 and the push plate 907 move down, the laser transmitter 19 and the laser receiver 20 move down synchronously, at first the laser receiver 20 cannot receive the laser emitted by the laser transmitter 19, when the laser emitted by the laser transmitter 19 hits the gap between the stator and the rotor, the laser receiver 20 can receive the laser emitted by the laser transmitter 19, when the laser receiver 20 cannot receive the laser emitted by the laser transmitter 19 again, the electric telescopic rod 904 is triggered to extend, the second piston 905 and the push plate 907 move right, if If the push plate 907 pushes the upper adjustment plate 9089 to move right, it means that the gap between the stator and the rotor is too small. If the push plate 907 pushes the lower adjustment plate 9089 to move right, it means that the gap between the stator and the rotor is too large. The rightward movement of any adjustment plate 9089 will drive the slide rail 9087 to move right, and the movable plate 911 and the third piston 912 are squeezed and move right. The fourth piston 913 and the unqualified seal 914 move down, thereby stamping an "×" on the stator, and the squeezing rod 9083 moves right with the slide rail 9087. After the squeezing rod 9083 releases the squeezing of the movable block 922, the movable block 922, the connecting column 921 and the valve plate 920 automatically pop up. , the hydraulic oil pressed from the second oil cylinder 906 into the fourth oil cylinder 916 will partially enter the fifth oil cylinder 919, the sixth piston 924 moves to the left, and the qualified seal 918 will not contact the stator. If the push plate 907 moves to the right between the two adjustment plates 9089, it means that the gap between the stator and the rotor is within the standard range, the extrusion rod 9083 still squeezes the movable block 922, and the valve plate 920 seals the fifth oil cylinder 919. The hydraulic oil pressed from the second oil cylinder 906 into the fourth oil cylinder 916 completely enters the fourth oil cylinder 916, and the fifth piston 917 and the qualified seal 918 move downward, thereby stamping the "√" sign on the stator, which is convenient for achieving the effect of automatic marking.

[0039] In summary, the generator stator-rotor gap measuring device achieves the purposes of convenient adjustment, detection, automatic marking, clamping and fixing, and hydraulic diversion, and meets people's usage needs.
