The flywheel 40 is provided with a flywheel spigot 41 for connecting with the carbon fiber coupling 50, and the flywheel spigot 41 is provided with a plurality of threaded holes 411 arranged along the circumferential direction. The carbon fiber coupler 50 is connected to a generator rotor in the generator housing 60 (since the generator rotor is disposed inside the engine housing 60, and a connection structure between the generator rotor and the generator housing 60 is the prior art, the generator rotor is not shown in the figure), a boss 51 capable of corresponding to the positions and the number of the plurality of threaded holes 411 is disposed on an end surface of the carbon fiber coupler 50 facing the generator rotor, a through hole is disposed at a center position of the boss 51, and the carbon fiber coupler 50 can be fixedly connected to the flywheel 40 by passing a connecting bolt through the through hole on the boss 51 and being in threaded connection with the threaded holes 411. Further, one end of the taper pin seat 20 can be connected with the boss 51, so that the taper pin 10 installed in the threaded hole 411 can pass through the through hole on the boss 51 and then enter the taper pin seat 20, in order to facilitate the smooth insertion of the taper pin 10 into the positioning hole of the taper pin seat 20 and prevent the damage of the carbon fiber coupler 50 caused in the process of inserting the carbon fiber coupler 50 into the flywheel spigot 41, the radial dimension of the connecting portion 12 should be smaller than the radial dimensions of the positioning hole and the through hole on the boss 51.
In this embodiment, first, the threaded portion 11 of the taper pin 10 is connected to the threaded hole 411 on the flywheel spigot 41, and the guide portion 13 is used to guide the entire taper pin 10 to be inserted into the positioning hole on the taper pin base 20, so as to position the relative position of the flywheel spigot 41 and the carbon fiber coupling 50, thereby ensuring that the carbon fiber coupling 50 can be accurately inserted into the flywheel spigot 41. In order to ensure further guarantee of the alignment effect, two sets of positioning devices, namely two taper pins 10 and two taper pin bases 202, can be adopted during assembly, the two taper pins 10 are fixed on the flywheel spigot 41 at intervals of 180 degrees, and the two taper pin bases 20 are fixed on the carbon fiber coupler 50 at intervals of 180 degrees correspondingly. Specifically, the taper of the guide portion 13 in this embodiment is 1: 8.
Further, in order to facilitate the rotation of the taper pin 10 so that the screw portion 11 thereof is connected to the screw hole 411, a clamping portion 14 is further provided at an end surface of the guide portion 13. The external force is received through the clamping portion 14 and the taper pin 10 is rotated, thereby screwing the threaded portion 11 of the taper pin 10 with the threaded hole 411.
To facilitate the clamping process, the clamping portion 14 in this embodiment is a regular hexagonal prism structure, and can be rotated by a hexagonal wrench.
As shown in fig. 1, the taper pin socket 202 in the present embodiment includes a spigot end 21, a support end 22, and a connecting plate 23. The spigot end 21 and the support end 22 are respectively arranged at two ends of the connecting plate 23 in the length direction, and the spigot end 21 is provided with a positioning hole for matching with the taper pin 10.
As shown in fig. 3, when the generator is assembled, the spigot end 21 is connected to the boss 51, and the support end 22 is connected to the generator, so that the taper pin seat 20 is fixed between the generator rotor and the carbon fiber coupler 50 for supporting the carbon fiber coupler 50, and the carbon fiber coupler 50 is prevented from being damaged by a large axial force during the assembly process.
In this embodiment, in order to facilitate connection between the spigot end 21 and the boss 51, a positioning groove 211 capable of being connected with the boss 51 on the carbon fiber coupler 50 in a matching manner is provided on an end surface of the spigot end 21 facing the carbon fiber coupler 50. In order to stably support the carbon fiber coupler 50 and adapt to carbon fiber couplers 50 and generator rotors with different distances, the positioning device in the embodiment further comprises an adjusting bolt 30, and the adjusting bolt 30 can be in threaded connection with the support end 22. The length of the adjusting bolt 30 extending out of the supporting end 22 is adjusted, so that the overall height of the positioning device is adjusted, and the supporting effect of the carbon fiber coupling 50 and the generator rotor with different intervals is met. Because taper pin seat 20 and adjusting bolt 30 have played the supporting role to the shaft coupling, in the assembling process, if carbon fiber shaft coupling 50 received axial direction's thrust, taper pin seat 20 and adjusting bolt 30 can withstand carbon fiber shaft coupling 50 to avoid carbon fiber shaft coupling 50 to take place to damage.
Further, the connecting plate 23 in this embodiment is provided with a groove 231 along its length direction. When the generator is assembled, the connecting plate 23 has certain deformability due to the arrangement of the grooves 231 in the connection process of the carbon fiber coupling 50 and the flywheel 40, and the carbon fiber coupling 50 is prevented from being damaged in the connection process of the carbon fiber coupling 50 and the flywheel 40 due to overlarge supporting force.
When the positioning device in the embodiment is used for assembling the generator, the spigot end 21 of the taper pin base 20 is connected with the boss 51, and the extension length of the adjusting bolt 30 is adjusted to enable the extension end of the adjusting bolt 30 to abut against the generator rotor, so that the taper pin base 20 is fixed between the generator rotor and the carbon fiber coupler 50. At the same time, the screw portion 11 of the taper pin 10 is screwed into the screw hole 411 of the flywheel 40, and the taper pin 10 is fixed to the flywheel spigot 41. After the taper pin 10 and the taper pin base 20 are connected and fixed, the generator and the carbon fiber coupler 50 are horizontally moved, and the guide part 13 of the taper pin 20 penetrates through the through hole on the boss 51 and the positioning hole on the taper pin base 20. The taper pin 10 gradually corrects the positions of the generator rotor and the carbon fiber coupling 50 by using the taper of the guide part 13, and finally accurately moves the carbon fiber coupling 50 into the flywheel spigot 41, and the threaded holes 411 on the flywheel spigot 41 correspond to the through holes on the boss 51 one by one. And then the carbon fiber coupler 50 is connected with the flywheel 40 through the connecting bolt, the taper pin 10 and the taper pin base 20 are detached after connection, and the original positions of the taper pin 10 and the taper pin base 20 are connected again through the connecting bolt. The removed taper pin 10 and taper pin base 20 can be used for the next generator assembly process.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention.
