Abstract
The utility model discloses a tool for shaping an end of a motor stator coil. The tool comprises a first shaping block, a second shaping block and two guide bars. The first shaping block and the second shaping block are of truncated cone structure and are symmetrically distributed. A pressure plate is arranged at a big-diameter end of each of the first shaping block and the second shaping block. The first shaping block and the second shaping block are internally provided with guide holes. The guide bars penetrate the first shaping block, the second shaping block and the two pressure plates through the guide holes. Each of two ends of the guide bars is provided with a limiting plate. Two ends of the guide bar are provided with limiting nuts on the outer side of the limiting plates. A hydraulic cylinder is arranged between the pressure plate of the second shaping block and the corresponding limiting plate. The tool provided by the utility model can effectively ensure the dimension of the end of the stator coil, and has high shaping efficiency.
Description
Technical field
The utility model relates to technical field of motors, relates in particular to a kind of motor stator coil end section shaping tool.
Background technology
The stator coil end of medium-sized freezing motor all needs shaping, then could normally assemble, use, generally adopt at present the manual method of knocking to complete the stator coil end shaping, the more difficult control of its size, concentricity is poor, easily damage the copper cash paint film while knocking, cause the insulating paper distortion, the wrinkle phenomenon, and the stator core notch easily produces breakage because of the stressed insulating paper that knocks, and be difficult to guarantee to cause withstand voltage the puncturing between the every phase of motor when knocking, raising along with product power, increasing of electromagnetic wire wire diameter is thick, the number of turn increases, make its end winding shaping adopt the manual method of knocking more to be difficult to, shaping efficiency is low, quality can't guarantee.
The utility model content
The utility model beats shaping and causes quality to guarantee in order to overcome in prior art motor stator coil end section, the inefficient deficiency of shaping, provide a kind of and can effectively guarantee the stator coil end size, the motor stator coil end section shaping tool that shaping efficiency is high.
To achieve these goals, the utility model adopts following technical scheme:
A kind of motor stator coil end section shaping tool, comprise the first dressing stick, the second dressing stick and two guide posts, described the first dressing stick and the second dressing stick integral body are truncated cone-shaped structure and symmetrical, described the first dressing stick, the bigger diameter end of the second dressing stick is respectively equipped with pressing plate, the first dressing stick, be provided with pilot hole in the second dressing stick, described guide post runs through the first dressing stick in pilot hole, the second dressing stick and two block pressur plates, the two ends of described guide post also are respectively equipped with limiting plate, the outside that the two ends of guide post are positioned at limiting plate is provided with stop nut, be provided with hydraulic cylinder between pressing plate on the second dressing stick and corresponding limiting plate.First remove lower the first dressing stick, then the second dressing stick end from coil of stator of motor together with guide post is stretched into, and pass from the other end, the other end of guide post is installed the first dressing stick and is passed through limiting plate, caging bolt is spacing, the conical surface of the first dressing stick is aimed at the coil of stator of motor other end, then the oil circuit of opening hydraulic cylinder makes the hydraulic cylinder extension end extend gradually, thereby make the first dressing stick, Distance Shortened between the second dressing stick, the first dressing stick, the conical surface on the second dressing stick is dilated shaping to motor stator coil end section, pull down the first dressing stick after orthopedic, the taking-up coil of stator of motor gets final product, use this kind of instrument can guarantee the size of each motor stator coil end section, shape is consistent, shaping quality is good, shaping efficiency is high.
As preferably, described hydraulic cylinder is the hand-hydraulic cylinder, and bottom and the limiting plate of hydraulic cylinder are fixed, and the telescopic end of hydraulic cylinder is connected with the pressing plate on the second dressing stick by adpting flange.The hand-hydraulic cylinder is convenient to control.
As preferably, described pressing plate is made by bakelite, and described the first dressing stick and the second dressing stick are made by nylon.Bakelite, nylon can not scratch the insulating barrier of coil in the shaping process.
As preferably, between pressing plate and the first dressing stick, the second dressing stick, bolt is connected.Pressing plate can be changed and adjust according to different coil of stator of motor sizes.
Therefore, the utlity model has effect and guarantee stator coil end size, the beneficial effect that shaping efficiency is high.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
A kind of motor stator coil end section shaping tool as shown in Figure 1, comprise the first dressing stick 1, the second dressing stick 2 and two guide posts 3, the first dressing stick 1 and the second dressing stick 2 integral body are truncated cone-shaped structure and symmetrical, the first dressing stick 1, the bigger diameter end of the second dressing stick 2 is respectively equipped with pressing plate 4, the first dressing stick 1, be provided with pilot hole 5 in the second dressing stick 2, guide post 3 runs through the first dressing stick 1 in pilot hole, the second dressing stick 2 and two block pressur plates 4, pressing plate 4 and the first dressing stick 1, between the second dressing stick 2, bolt connects, in the present embodiment, pressing plate 4 is made by bakelite, the first dressing stick 1 and the second dressing stick 2 are made by nylon, the two ends of guide post 3 also are respectively equipped with limiting plate 6, two limiting plates are positioned at the outside of two block pressur plates, the two ends of guide post 3 are through limiting plate 6, the guide post in limiting plate 6 outsides is provided with stop nut 7, be provided with hydraulic cylinder 8 between pressing plate 4 on the second dressing stick 2 and corresponding limiting plate 6, in the present embodiment, hydraulic cylinder 8 is the hand-hydraulic cylinder, the bottom of hydraulic cylinder 8 and limiting plate 6 are fixing, and the telescopic end of hydraulic cylinder 8 is connected with the pressing plate 4 on the second dressing stick 2 by adpting flange 9.
By reference to the accompanying drawings, using method of the present utility model is as follows: as shown in Figure 2, stator coil and this kind of shaping tool are installed together, the conical surface of the first dressing stick 1 and the second dressing stick 2 stretches into respectively the stator coil two ends, then open the hand-hydraulic cylinder, the hydraulic cylinder extension bar stretches out, thereby make the second dressing stick move to the first dressing stick along guide post, stator coil dilates shaping under the effect of the first dressing stick 1 and second dressing stick 2 conical surfaces, a stator coil reshaping well afterwards takes off and changes another stator coil, repeat above-mentioned action and continue shaping, stator coil end shape after each shaping, size is all identical, shaping effect is good.Therefore, the utlity model has effect and guarantee stator coil end size, the beneficial effect that shaping efficiency is high.
