Description

Technical Field

[0001] The utility model relates to the technical field of rotor assembly and positioning, in particular to a generator rotor assembly and positioning tool. Background Art

[0002] A generator is a device that converts mechanical energy into electrical energy. The generator rotor is the rotating part of the generator. To ensure the normal operation of the generator, a positioning assembly is generally required to assemble the rotor shaft in the generator rotor to ensure the stability of subsequent rotor movement;

[0003] Chinese patent authorization announcement number CN219802120U discloses a generator rotor assembly positioning tool, including a fixed plate, a bottom frame is fixedly connected to the upper part of the fixed plate, a plurality of fixed blocks are fixedly connected inside the bottom frame, a slide groove is provided on both sides of the fixed block, a slider is slidably connected to the outside of the fixed block, and two limit blocks are fixedly connected inside the slider. When assembling the rotor, the generator rotor assembly positioning tool does not require workers to manually adjust the positioning parts, thereby reducing the positioning deviation and improving the rotor assembly effect, thereby improving the positioning effect of the generator rotor assembly positioning tool. The above-mentioned prior art solution has the following shortcomings: the rotor assembly positioning tool is mainly locked by the rotation of the servo motor during use, so that the plurality of clamping blocks move inward to realize the automatic positioning and clamping of the rotor shaft, but the clamping effect can only be achieved by the self-locking effect of the servo motor itself in order to ensure its stability and reliability, that is, no additional locking is set in the clamping and positioning effect. When the servo motor is damaged, the rotor shaft cannot be effectively fixed after the clamping of the clamping block is completed, so there is a certain room for improvement. Utility Model Content

[0006] When a generator rotor assembly positioning tool is used using the technical solution, the meshing effect between the first flexible teeth and the second flexible teeth enables the first flexible teeth to move along the inclined surface when the movable seat approaches inward, and when the movable seat moves in the opposite direction, the parallel effect of the right-angle sides of the first flexible teeth and the second flexible teeth is used to lock the position of the movable seat, thereby further ensuring the stability of the rotor shaft clamping, and this self-locking method does not require the cooperation of electrical components, thereby improving its economy.

One end of the connecting plate 4 is hinged to the outer side of the top of the turntable 3, and the other end of the connecting plate 4 is hinged to one side of the moving seat 5. One end of the connecting plate 4 is installed with a moving seat 5, and the bottom end of the moving seat 5 is installed with a slider 7, and the inside of the lower assembly disk 1 below the slider 7 is correspondingly provided with a slide groove 8, and the position of the slide groove 8 corresponds to the position of the guide hole 13 one by one. The top of the moving seat 5 passes through the inside of the guide hole 13, and the inner side of the top of the moving seat 5 is installed with a clamping plate 6. A through hole 9 is opened inside the seat 5, and a connecting block 12 is installed inside the through hole 9, first flexible teeth 10 are installed on both sides of the connecting block 12, and the inner side of the guide hole 13 on one side of the first flexible tooth 10 is correspondingly installed with a second flexible tooth 15, and the second flexible teeth 15 are provided in three groups, and each group is provided with a plurality of teeth, and each group of second flexible teeth 15 is symmetrically distributed about the central axis of the guide hole 13, and the cross-sections of the second flexible teeth 15 and the first flexible teeth 10 are both right triangles, and the second flexible teeth 15 and the first flexible teeth 10 are meshed with each other.

[0031] In this embodiment, when in use, the rotor shaft is placed inside the assembly groove 14, and the knob 204 is turned to rotate the worm 203. Since the worm 203 and the worm wheel 202 are meshed with each other, the worm wheel 202 drives the turntable 3 to rotate, so that the turntable 3 pulls one end of the connecting plate 4, so that the connecting plate 4 pulls the moving seat 5 inward, so that the multiple moving seats 5 move inward synchronously, and the slider 7, the slide groove 8 and the guide hole 13 cooperate to limit the moving direction of the moving seat 5, so that the three moving seats 5 form a shrinking circle effect inward, so that the clamping plate 6 clamps and fixes the internal rotor shaft, and the worm 203 is used to mesh with the worm wheel 202. 3 and the self-locking property of the worm gear 202 to prevent the moving seat 5 from loosening outward.
