Abstract
Description
Technical Field
[0001] The utility model relates to a motor wire embedding. Background Art
[0002] As more and more industries apply permanent magnet motors, traditional motors are difficult to meet the demand. In order to meet production needs, it is sometimes necessary to manufacture some slender motors. Since slender motors are too long, it is difficult to press the wires and close the notches, which seriously restricts the development of such motors. A small number of companies have specially made some extra-long wire insertion tools, but they are inconvenient to use and have low wire insertion efficiency.
[0003] At present, special extra-long wire embedding tools are generally used for embedding wires of slender motors. Extra-long wire embedding tools are generally extended wire crimping knives specially made according to the shape of the motor stator. On the one hand, when embedding wires in the iron core of a slender motor, the length of the wire crimping knife handle is as long as the length of the iron core. The wire crimping knife must be made according to the length of the motor iron core. A 1-meter motor should have a 1-meter long wire crimping knife, and a 2-meter motor should have a 2-meter long wire crimping knife. The processing of the over-long wire crimping knife's knife bar is extremely difficult, which greatly increases the production cost and difficulty, and one wire crimping knife can only embed wires for one type of motor. On the other hand, for the embedding work of slender motors, since the motor is too long, if such an extended wire crimping knife is used, the rod is light and the strength is insufficient, which will cause problems such as difficulty in crimping and difficulty in closing the notch. If the extended wire crimping knife is to be strong enough, the weight will increase a lot, and it is also extremely inconvenient for workers to use such a heavy wire crimping knife for precision work.

[0025] The elongated motor wire inserting tool of the present utility model embodiment comprises: a wire pressing body fixing frame 4; a wire pressing blade 6; two pairs of bearings, namely a first bearing 21, a second bearing 22, a third bearing 23 and a fourth bearing 24; first to fourth adjustment rings 31, 32, 33 and 34; first to fourth screws 11, 12, 13 and 14. They are fasteners for fastening the bearings; a first shaft 91 and a second shaft 92; and two flexible ropes, namely a first flexible rope 81 and a second flexible rope 82.
[0026] The wire pressing blade 6 is located below the wire pressing body fixing frame 4, and the wire pressing blade 6 is an integral structure with the wire pressing body fixing frame 4. The wire pressing blade 6 is an inverted T-shaped structure blade, and two groove structures are formed at the bottom of the left and right sides of the wire pressing body fixing frame 4.
[0027] The two pairs of bearings are fixed to both sides of the pressing body fixing frame 4 by fasteners and act as two pairs of rollers.
[0028] The first to fourth adjustment rings 31, 32, 33 and 34 are all rigid ring structures. The distance between each pair of bearings and the wire pressing body fixing frame 4 is adjusted by the adjustment ring, thereby adjusting the spacing between each pair of bearings. The matching size of the wire pressing blade 6 and the motor slot is adjusted by replacing the bearings and the adjustment ring.
[0029] The two ends of the wire pressing body fixing frame 4 are respectively provided with a first flexible rope connecting plate 5 and a second flexible rope connecting plate 52, and the two flexible rope connecting plates are both located on the longitudinal axis of the wire pressing body fixing frame. In this embodiment, two flexible ropes are respectively connected to the first wire drawing through hole 71 and the second wire drawing through hole 72 on the flexible rope connecting plate.
