Description

Technical Field

[0001] This utility model relates to the field of motor assembly and processing technology. Specifically, it relates to a combined 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] During motor coil assembly, ensuring adequate filling of the sides of the coil is a crucial technical requirement and an important measure to reduce vibration and electrochemical corrosion during operation. The side filling technique for motor coils is a significant aspect of large motor assembly, with the main challenge being the unevenness of the gaps on one side of the coil assembly, which is also difficult to inspect.

[0003] The single-sided gap of the motor coil assembly is determined by the interaction of the straightness of the iron core slot, the straightness of the coil side, and the coil installation state. The actual range of the single-sided gap of the motor coil assembly is generally 0 to 0.5 mm. The gap is uneven in the depth and length directions of the iron core slot and has no regularity. The unevenness in the depth direction is difficult to detect.

[0004] Therefore, there is an urgent need for a modular fixture that brings the motor coil close to one side, while leaving a gap of 0.2–0.5 mm on the other side. This would allow for the installation of a filler material of appropriate thickness on the side with the larger gap, thus achieving the technical requirement of adequate side filling. The difficulty lies in the fact that, besides the aforementioned side gap, the only available space on the side of the motor coil is the iron core ventilation groove, which limits the installation space available for mounting the fixture that brings the motor coil close to one side. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a combined tooling that brings the motor coil close to one side. During the assembly of the motor coil, it can be installed at the ventilation groove of the iron core, so that the motor coil is close to the side of the iron core winding groove, so as to facilitate the subsequent filling of the side gap filling material.

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

[0007] A combined tooling for bringing a motor coil close to one side includes an L-shaped support plate and a stopper strip. The support plate includes a plate body and a support handle located on the top of the plate body. The support handle has a protruding force-bearing point on the side away from the plate body. The stopper strip is located on the side of the plate body near the force-bearing point and contacts the force-bearing point.

[0008] In a further technical solution, the plug is shaped like a large and small head, with the small end inserted into the gap between the support plate and the iron core ventilation channel steel, and the large end provided with several spaced first disassembly holes for installing a pin during disassembly.

[0009] A further technical solution is that the plate body is provided with a second disassembly hole for installing a protective rope, which facilitates installation.

[0010] In a further technical solution, during use, the force-bearing point of the support plate is located at the center of the side of the coil.

[0011] In a further technical solution, the connection between the plate and the support handle is at a right angle. Beneficial effects

[0012] Compared with the prior art, the present invention has the following significant advantages:

[0013] When installing the motor coil, this utility model allows the motor coil to be close to one side of the iron core winding groove, while the gap between the coil and the other side of the iron core winding groove is 0.2 to 0.5 mm. This allows for the installation of a filling material of appropriate thickness on the side with a larger gap, thus meeting the technical requirements for filling the side of the motor coil with filling material.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Example

[0019] like Figure 1-3 As shown, a combined tooling for bringing a motor coil close to one side includes an L-shaped support plate 1 and a plug strip 2. The support plate 1 includes a plate body 1-1 and a support handle 1-2 located on the top of the plate body 1-1. The support handle 1-2 has a protruding force-bearing point 1-3 on the side away from the plate body 1-1. The plug strip 2 is located on the side of the plate body 1-1 near the force-bearing point 1-3 and contacts the force-bearing point 1-3.

[0020] The plug strip 2 is shaped like a large and small head. Its small head is inserted into the gap between the support plate and the iron core ventilation channel steel 7. Its large head is provided with several spaced first disassembly holes 2-1 for installing the pin during disassembly.

[0021] The plate 1-1 is provided with a second disassembly hole 1-4 for installing a protective rope, which facilitates installation.

[0022] When in use, the force-bearing points 2-3 are located at the center of the side of the coil, which makes it easier for the coil to be subjected to uniform force and move more smoothly to the other side.

[0023] The connection between the plate and the support handle is at a right angle, which facilitates fitting and positioning with the side of the coil.

[0024] The installation and use methods of this utility model are as follows:

[0025] 1. When assembling the motor coil, first insert the motor coil into the iron core winding slot, then press the inner side of the support handle of the support plate against the opposite side of the motor coil to be pressed against, and press the plate body of the support plate against one side of the motor coil.

[0026] 2. Then install the plug strip in the ventilation slot of the iron core. One side of the small end of the plug strip contacts the stress point of the support plate, and the other side of the small end of the plug strip contacts the steel of the ventilation slot of the motor iron core.

[0027] 3. Tapping the large end and the small end of the stopper will cause the stopper to move forward and press against the support plate. The support plate will then press against the motor coil, causing the motor coil to move to the other side under pressure, thus bringing the motor coil close to one side.

[0028] 4. If multiple coils are installed in the iron core winding slot, the above method can be used to first place a single layer of coil on only one side, and then repeat the above steps to place the next layer of coil on only one side, so that all coils in the iron core winding slot can be placed on only one side.
