[0002] During the installation of the generator rotor, the field winding and the yoke are installed on the generator shaft, and then two claw poles facing each other are installed. When the claw poles are installed to the claw pole installation position of the shaft, the claw poles are locally squeezed to compact the yoke and fix it. The existing assembly is generally completed manually, and manual assembly is difficult to ensure the overall assembly accuracy. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a claw pole installation and positioning auxiliary device to overcome the deficiencies in the above-mentioned prior art.

[0004] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: a claw pole installation positioning auxiliary device includes a base and a positioning assembly, the base is provided with a socket, a plurality of positioning assemblies are arranged on a circle with the socket as the center, and the angle distribution of the plurality of positioning assemblies matches the angle distribution of the pawl of the claw pole to be installed, the positioning assembly includes a positioning column and a positioning plate, the positioning column is arranged on the base, the positioning plate is arranged on the positioning column, and the positioning plate is provided with a positioning groove matching the tip of the pawl of the claw pole.

[0005] The beneficial effect of the present invention is that when two claw poles, a magnetic field winding and a yoke need to be installed on a rotating shaft, the rotating shaft is first passed through the insertion hole, and then one of the claw poles is sleeved on the rotating shaft, and the pawl is ensured to face upwards, and then the positioning column is inserted between the pawls of the claw pole, so that the claw pole is circumferentially positioned, and then the magnetic field winding and the yoke are installed on the rotating shaft, and finally another claw pole is installed on the rotating shaft, with the pawl of the claw pole facing downwards, and the tip of the pawl is inserted into the positioning groove, so that the claw pole is also circumferentially positioned and is not easy to shake, so that the overall assembly accuracy is easy to ensure during manual assembly, and the gaps between the pawls of the two claw poles are equal.

[0006] Based on the above technical solution, the present invention can also be improved as follows.

[0007] Furthermore, the positioning assembly also includes a linear lifting mechanism, which is arranged on the positioning column, and the positioning plate is arranged on the linear lifting mechanism.

[0008] The above method has the further beneficial effect of being able to meet the installation and positioning requirements of claw poles, field windings and yokes of different heights, and at the same time being able to adjust the distance between the upper claw pole and the field winding, the yoke and the lower claw pole to meet actual assembly requirements.

[0009] Furthermore, the linear lifting mechanism includes a positioning sleeve and a stopper. The lower end of the positioning sleeve is threadedly connected to the positioning column. The positioning plate is movably arranged at the opening at the upper end of the positioning sleeve. One end of the stopper is connected to the positioning column. The other end of the stopper is connected to the positioning plate after passing through the inner cavity of the positioning sleeve.

One end of the anti-rotation column extends into the installation cavity after passing through the through hole. The other end of the anti-rotation column is connected to the positioning plate. The stop block and the spring are arranged in the installation cavity. The stop block is connected to the anti-rotation column. The spring is sleeved on the anti-rotation column, and the two ends of the spring respectively press against the stop block and the interface between the installation cavity and the through hole. During the return process, the spring ensures that the lower end face of the positioning plate is always in contact with the upper end face of the positioning sleeve.

[0012] A further beneficial effect of the above method is that during the height adjustment process, the positioning plate can be effectively prevented from rotating, thereby ensuring that the positioning groove on the positioning plate is always at the initial angle, so that the assembly accuracy is not affected.

[0013] Furthermore, the anti-rotation part also includes a mounting platform, which is arranged at the opening at the upper end of the positioning sleeve. The two ends of the anti-rotation column are respectively connected to the stop block and the mounting platform. During the return process, the spring ensures that the lower end surface of the mounting platform is always in contact with the upper end surface of the positioning sleeve, and the positioning plate is arranged on the mounting platform.

[0015] Furthermore, the positioning plate is detachably arranged on the mounting table.

[0016] Furthermore, the mounting platform is provided with a plurality of positioning holes, and the positioning plate is provided with a plurality of positioning pins corresponding to the positioning holes.

[0017] A further beneficial effect of the above method is that a positioning plate with positioning grooves of different sizes can be selected according to the different sizes of the claws of the claw poles, thereby expanding the application range of the claw pole installation positioning auxiliary device.

[0018] Furthermore, the positioning assembly also includes a slider and a locking bolt. A slide groove pointing to the center of the socket is provided at the installation location of each positioning assembly on the base. The slider in each positioning assembly is movably arranged in the slide groove corresponding to the positioning assembly, and the slider is connected to the positioning column. The bottom of the slide groove is provided with an adjustment groove that passes through the base. The locking bolt is arranged outside the base, and the screw of the locking bolt is threadedly connected to the slider after passing through the adjustment groove.

[0019] A further beneficial effect of adopting the above method is that claw poles of different diameters can be installed and positioned, and the application range is wide. When claw poles of different diameters are installed and positioned, the locking bolt is rotated so that the slider can move in the slide groove. After moving to the corresponding position, the locking bolt is tightened so that the slider is fixed in the slide groove under the action of the locking bolt, thereby changing the diameter of the circle surrounded by all positioning components.
