Description

Technical Field

[0001] The present invention relates to the technical field of installation positioning tools, and particularly relates to a positioning tool for installing a magnetic pole connecting wire and a hole matching method. Background Art

[0002] Existing motors, such as Figure 1 as shown, include a rotor yoke 1, magnetic poles 2, and a plate-shaped magnetic pole connecting wire 3. The top of the yoke 1 has a screw 11, and the magnetic poles 2 have plate-shaped magnetic pole leads 21. The magnetic pole connecting wire 3 is fixed on the screw 11. The magnetic pole connecting wire 3 has a fitting portion 31, and the fitting portion 31 is in fitting connection with the magnetic pole lead 21. During on-site assembly of the motor rotor magnetic poles, since the upper end of the screw 11 is at a relatively high height, it is impossible to keep the magnetic pole connecting wire 3 in a horizontal state and naturally fit the fitting portion 31 with the magnetic pole lead 21. The on-site treatment method is to first fit the fitting portion 31 with the magnetic pole lead 21, then use a straightedge to compare and draw the center of the installation hole on the magnetic pole connecting wire 3 and then match the hole; after matching the positioning hole for fitting with the screw 11, the magnetic pole connecting wire 3 is fixed on the screw 11 through an insulating spacer and a nut, then the magnetic pole connecting wire is adjusted to be horizontal by a level, and then the installation holes of the fitting portion 31 and the magnetic pole lead 21 are positioned and matched. This hole matching method is implemented by on-site installers. Due to the narrow construction space, there are errors in manual adjustment of the level and positioning, and there are also observation errors when different people work, resulting in a large error in the position of the final positioning hole. As a result, after the magnetic pole connecting wire 3 and the screw 11 are assembled on-site, the contact surface between the fitting portion 31 and the magnetic pole lead 21 cannot be naturally fitted, and manual correction is required in the later stage. However, when correcting the magnetic pole connecting wire 3 in the later stage, the structure of the magnetic pole connecting wire 3 itself will be changed to a certain extent, resulting in a change in the original design stress point of the magnetic pole connecting wire 3 during the operation of the rotor, and even affecting the service life of the magnetic pole connecting wire 3.

Detailed implementation mode

[0030] The following will further describe the present invention in detail with reference to the specification drawings and specific embodiments.

[0031] Figures 1 to 6 An embodiment of the positioning tool for installing the magnetic pole connection wire of the present invention is shown. The positioning tool for installing the magnetic pole connection wire includes a positioning plate 4 and a fixing plate 5. The top of the positioning plate 4 is provided with a first fitting surface 41 for fitting with the fitting part 31 of the magnetic pole connection wire 3 and a support surface 42 for supporting the fitting part 31. The bottom of the positioning plate 4 is provided with a second fitting surface 43 for fitting with the magnetic pole lead wire 21. The first fitting surface 41 and the second fitting surface 43 are arranged coplanarly. The fixing plate 5 is fixed to the positioning plate 4 through a fastening piece 6 for clamping the magnetic pole lead wire 21 on the second fitting surface 43. When in use, first fix the positioning plate 4 on the magnetic pole lead wire 21. Specifically, first fit the second fitting surface 43 with the magnetic pole lead wire 21, and then fasten the fixing plate 5 to the positioning plate 4 through the fastening piece 6 to clamp the magnetic pole lead wire 21. Then support the fitting part 31 of the magnetic pole connection wire 3 on the support surface 42 of the positioning plate 4, and place the magnetic pole connection wire 3 on the screw 11 (an adjusting device can be installed on the screw 11 to adjust the height to adjust the levelness of the magnetic pole connection wire 3), which is convenient for adjusting the horizontal position of the magnetic pole connection wire 3 so as to accurately determine the fixing position of the magnetic pole connection wire 3, so that after the magnetic pole connection wire 3 is fixed to the screw 11, the fitting part 31 is closely fitted with the first fitting surface 41. The positioning tool for installing the magnetic pole connection wire has a simple structure, is convenient for adjusting the horizontal position of the magnetic pole connection wire 3 and improves the fixing accuracy of the magnetic pole connection wire 3.

[0032] In this embodiment, as Figures 2 to 4As shown, the orientations of the first fitting surface 41 and the second fitting surface 43 are opposite. Specifically, a fitting plate 45 is provided at the top of the positioning plate 4. The first fitting surface 41 is formed on one side of the fitting plate 45, and the supporting surface 42 is formed on the top surface of the positioning plate 4. A positioning groove 44 is recessed on one side of the bottom of the positioning plate 4, and the second fitting surface 43 is formed on the bottom surface of the positioning groove 44. The fixing plate 5 is fixed to both sides of the positioning groove 44 through fasteners 6, and the positioning plate 4 is convenient to fasten. During use, the magnetic pole lead 21 is fitted and inserted into the positioning groove 44, and the magnetic pole lead 21 is in contact with the bottom surface (the second fitting surface 43) of the positioning groove 44. The positioning groove 44 has a limiting effect on the magnetic pole lead 21, which is convenient for the installation of the positioning plate 4.

[0033] In this embodiment, as Figure 1 and Figure 6 shown, the positioning tool for installing the magnetic pole connecting wire further includes an adjusting nut 7 for cooperating with the screw 11. A marking member 71 for marking the fixed position of the magnetic pole connecting wire 3 is provided at the top of the adjusting nut 7. During use, the adjusting nut 7 is screwed onto the screw 11. While the fitting portion 31 of the magnetic pole connecting wire 3 is supported on the supporting surface 42 of the positioning plate 4, the magnetic pole connecting wire 3 is placed on the adjusting nut 7, and the magnetic pole connecting wire 3 is adjusted to the horizontal position by adjusting the adjusting nut 7, which is convenient for adjustment.

[0034] In this embodiment, the marking member 71 has a marking tip 711 for pressing into the magnetic pole connecting wire 3 to mark the fixed position of the magnetic pole connecting wire 3, which is beneficial to the accurate positioning of the magnetic pole connecting wire 3 and the screw 11. Specifically, the marking member 71 is a cone, and the marking tip 711 is formed at the top of the cone, and the bottom end of the cone is provided on the adjusting nut 7.

[0035] A method for matching holes for installing a magnetic pole connecting wire, which is carried out by using a positioning tool for installing a magnetic pole connecting wire, includes the following steps:

[0036] S1: Fix the positioning plate 4 on the magnetic pole lead 21: First, make the second fitting surface 43 contact the magnetic pole lead 21, and then fasten the fixing plate 5 to the positioning plate 4 through the fastener 6 to clamp the magnetic pole lead 21;

[0037] S2: Screw the adjusting nut 7 onto the screw 11;

[0038] S3: Mark the fixed position of the magnetic pole connection wire 3: Support the fitting part 31 of the magnetic pole connection wire 3 on the support surface 42 of the positioning plate 4, and place the magnetic pole connection wire 3 on the adjusting nut 7. Then, adjust the adjusting nut 7 to make the magnetic pole connection wire 3 in a horizontal position. At this time, the fitting part 31 fits with the first fitting surface 41. Finally, apply a downward force to the magnetic pole connection wire 3 so that the marking component 71 makes a mark at the fixed position of the magnetic pole connection wire 3. Among them, the horizontal position measurement of the magnetic pole connection wire 3 is detected by placing a horizontal positioning device (such as a level) on the magnetic pole connection wire 3. The force application method of the magnetic pole connection wire 3 is to place a flexible cushion block (such as a small wooden block) on the magnetic pole connection wire 3, and then gently tap the flexible cushion block with a rubber hammer to press the magnetic pole connection wire 3 onto the marking tip 711 of the marking component 71 to form an imprint.

[0039] S4: Prepare a positioning hole for the screw 11 to penetrate at the marked position. Specifically, drill a hole in the magnetic pole connection wire 3 with the imprint as the center, that is, form a positioning hole.

[0040] Fixing of the magnetic pole connection wire 3: Remove the adjusting nut 7 and the positioning plate 4, then directly fit the fitting part 31 of the magnetic pole connection wire 3 with the magnetic pole lead 21, and make the positioning hole align with the screw 11. Finally, fix the magnetic pole connection wire 3 on the screw 11 by adding an insulating cushion block and a nut on the screw 11.

[0041] Through this method, the adjustment of the horizontal position of the magnetic pole connection wire 3 is convenient, and the positioning holes on the magnetic pole connection wire 3 are accurately positioned with the screw 11 when the fitting part 31 fits with the magnetic pole lead 21. So that after the magnetic pole connection wire 3 is fixed with the screw 11, the fitting part 31 and the magnetic pole lead 21 form a surface fit, improving the service life of the magnetic pole lead 21.
