Description

Technical Field

[0001] This utility model relates to the field of motor assembly and processing technology. Specifically, it relates to a plug-type tooling that brings the motor coil close to one side. During motor coil assembly, the motor coil is brought close to the iron core slot, which facilitates the installation of side gap filling material. Background Technology

[0002] When assembling motor coils, side filling is a crucial aspect of assembling large motors. The main challenge lies in the unevenness of the unilateral gap in the coil assembly, which is difficult to detect. The unilateral gap in the motor coil assembly is determined by the interplay of the straightness of the core slot, the straightness of the coil side, and the coil's installation condition. The actual range of the unilateral gap is generally 0–0.5 mm. However, the unevenness in the depth and length of the core slot is irregular, and the unevenness in the depth direction is particularly difficult to detect.

[0003] If the motor coil can be positioned close to the iron core slot on one side, while the gap on the other side is 0.2–0.5 mm, then a filler material of appropriate thickness can be installed on the side with the larger gap, achieving the technical requirement of adequate side filling. During motor coil assembly, adequate side filling will reduce vibration and electro-corrosion during operation, improve quality, and extend the motor's service life.

[0004] However, there is a technical challenge: apart from the side gap, the only available tooling for installing the motor coil is the iron core ventilation slot. Therefore, there is an urgent need for a tooling that uses the iron core ventilation slot to bring the motor coil close to one side. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a plug-type tooling that brings the motor coil close to one side. During the assembly of the motor coil, the motor coil is brought close to the iron core slot, which facilitates the subsequent filling of the side gap with filling material.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A plug-type tooling for pressing a motor coil close to one side includes a disassembly handle and a plate-shaped plug. The plug is located on one side of the end of the disassembly handle, and one side of the plug has a vertical reinforcing rib corresponding to the ventilation groove of the iron core.

[0008] In a further technical solution, the thickness of the top of the disassembly handle is greater than the thickness of the reinforcing rib, and the thickness of other parts of the disassembly handle, except for the top, is less than the thickness of the reinforcing rib.

[0009] A further technical solution is that the disassembly handle has a protective sleeve on the bottom side opposite to the reinforcing rib.

[0010] A further technical solution is that the bottom of the disassembly handle is provided with an installation groove, and a protective sleeve is installed inside the installation groove.

[0011] In a further technical solution, the protective sleeve is fixed to the bottom of the disassembly handle by adhesive.

[0012] In a further technical solution, the width of the reinforcing rib is slightly smaller than that of the ventilation groove in the iron core.

[0013] In a further technical solution, the bottom of the stopper plate is sword-shaped.

[0014] A further technical solution is that the disassembly handle is provided with an elongated hole.

[0015] In a further technical solution, the thickness of the stopper plate is 0.2–0.5 mm. Beneficial effects

[0016] Compared with the prior art, the present invention has the following significant advantages:

[0017] In this invention, when installing the motor coil, by placing the reinforcing rib along the ventilation groove of the iron core and pressing the motor coil with the plug plate, the motor coil can be made to be close to one side of the iron core winding groove, while the gap on the other side is 0.2 to 0.5 mm. The corresponding thickness of filling material can be filled on the side with the larger gap. Attached Figure Description

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Example

[0028] like Figure 1 As shown in Figure 5, a plug-type tooling for pressing a motor coil close to one side includes a disassembly handle 1 and a sheet-like plug plate 2. The plug plate 2 is located on one side of the tail of the disassembly handle 1, and a reinforcing rib 3 corresponding to the ventilation groove of the iron core is provided vertically on one side of the plug plate 2.

[0029] The top thickness of the disassembly handle 1 is greater than the thickness of the reinforcing rib 3. Except for the top, the thickness of other parts of the disassembly handle 1 is less than the thickness of the reinforcing rib 3. The greater thickness at the top of the disassembly handle facilitates the application of hammering during use. The smaller thickness of other parts avoids interference with the iron core during use, protecting the iron core and the tooling.

[0030] The disassembly handle 1 has a protective sleeve 4 on the bottom side opposite to the reinforcing rib 3 to protect the coil and prevent the tooling from directly contacting the coil during use, thus protecting the coil.

[0031] The bottom of the disassembly handle has an installation groove, and the protective sleeve 4 is placed in the installation groove. The protective sleeve 4 is fixed to the bottom of the disassembly handle by adhesive. In addition to the two installation methods mentioned above, the protective sleeve can also be fixed to the bottom of the disassembly handle by other methods.

[0032] The width of the reinforcing rib 3 is slightly smaller than that of the iron core ventilation groove 5, so that the reinforcing rib can be placed into the iron core ventilation groove.

[0033] The bottom of the plug plate 2 is sword-shaped, which facilitates its insertion into the gap between the motor coil and the iron core winding groove wall.

[0034] The disassembly handle 1 is provided with an elongated hole 1-1 to facilitate the disassembly of the extrusion coil tooling.

[0035] The thickness of the stopper plate is 0.2–0.5 mm. This invention can be used to manufacture multiple toolings of different specifications, mainly differing in the thickness of the stopper plate, while other structures and dimensions remain the same, with the thickness increasing sequentially.

[0036] The installation and use methods of this utility model are as follows:

[0037] 1. For example Figure 6-8As shown, when assembling the motor coil, the coil 6 is first inserted into the iron core winding groove 7. The reinforcing rib is then pressed down along the side of the iron core ventilation groove 5 and installed into the gap between the motor coil 5 and one side of the groove wall of the iron core winding groove 7. The top of the disassembly handle 1 can be gently tapped to allow the plug plate 2 to be fully inserted, so that the motor coil can be moved to the other side.

[0038] 2. Using the method described above, insert the tooling with increasing thickness into the gap between the motor coil and the iron core winding groove wall, so that the motor coil gradually moves closer to the other side until the tooling with a thicker coil cannot be inserted, thus achieving the goal of the motor coil being close to one side.
