Description

Technical Field

[0001] This utility model relates to the field of stator coil winding technology, specifically to a stator coil winding auxiliary positioning device. Background Technology

[0002] In simple terms: the stationary part of an electric motor is called the stator, which has pairs of DC-excited stationary main magnetic poles mounted on it; the rotating part, the rotor, is called the armature core, on which the armature windings are mounted. When energized, they generate an induced electromotive force, which acts as a rotating magnetic field. This, in turn, produces electromagnetic torque for energy conversion. Based on the shape and mounting method of the stator windings, stator windings can be divided into two categories: centralized and distributed.

[0003] During the production of motor stators, coils are often embedded inside to facilitate the subsequent provision of magnetic torque to the stator. This requires a stator winding machine. When embedding coils into the stator using a stator winding machine, the stator is often placed on the outside of the cable fixing frame. However, in actual operation, due to the different sizes of stators, it is impossible to manually load and unload larger stators, which affects the subsequent winding of the stator and cannot meet the actual use requirements.

[0027] Example

[0028] The stator coil winding auxiliary positioning device provided in this embodiment, such as Figures 1-5 As shown, the system includes a base plate 1, a stator winding machine 2 fixedly mounted on the rear side of the top of the base plate 1, a wire insertion rack 4 fixedly mounted on the front side of the stator winding machine 2, a fixing mechanism 3 on the top of the stator winding machine 2, and an auxiliary positioning and feeding mechanism 5 on the top of the base plate 1 and in front of the stator winding machine 2. The base plate 1 is used to install the stator winding machine 2 and place the auxiliary positioning and feeding mechanism 5, while facilitating the subsequent movement of the auxiliary positioning and feeding mechanism 5. The stator winding machine 2 is used to install the fixing mechanism 3 and the wire insertion rack 4. The wire insertion rack 4 is used to accommodate the coil to be inserted and to fix the stator for subsequent coil insertion. The fixing mechanism 3 is used to block the stator sleeved on the outside of the wire insertion rack 4. The auxiliary positioning and feeding mechanism 5 is used to support and place larger or heavier stators for subsequent movement.

[0029] The auxiliary positioning and feeding mechanism 5 includes a mounting base 501 placed on the top of the base plate 1. The mounting base 501 has a receiving groove 502 inside. A fixed extrusion frame 504 is fixedly installed on the top of the mounting base 501 and behind the receiving groove 502. A movable extrusion frame 503 is provided on the top of the mounting base 501 and inside the receiving groove 502. The receiving groove 502 is provided to receive the stator. The movable extrusion frame 503 and the fixed extrusion frame 504 are used to limit and extrude the stator to fix it, increase the stability of the stator and facilitate subsequent wire embedding.

[0030] The top of the mounting base 501 has two slide grooves 506, and a slider 508 is slidably connected inside the slide groove 506. The top of the slider 508 is fixedly connected to the bottom of the movable extrusion frame 503. The slide grooves 506 and slider 508 are used to fix the movable extrusion frame 503.

[0031] The mounting base 501 has two threaded rods 507 rotatably connected inside by bearings. The rear side of the threaded rods 507 extends into the interior of the slide groove 506 and is connected to the slider 508 by threads. The engagement between the threaded rods 507, the slider 508 and the threads drives the moving extrusion frame 503, thereby enabling the placement and limiting of stators of different sizes.

[0032] Four support rods 505 are fixedly installed at the bottom of the mounting base 501. The bottom of the support rods 505 is round. The support rods 505 are used to support the mounting base 501. The material of the support rods 505 is a wear-resistant material, which is selected according to production. The round bottom of the support rods 505 is used to reduce friction with the top of the base plate 1 and facilitate the overall movement. The universal wheels are not provided in this solution because the turning radius required by the universal wheels when turning would affect the subsequent placement of the stator, which is placed inside the receiving groove 502, on the outside of the wire insertion bracket 4.

[0033] The fixing mechanism 3 includes four first hydraulic rods 302 disposed on the top of the stator winding machine 2 and two second hydraulic rods 304 disposed above the first hydraulic rods 302. The output end of the second hydraulic rods 304 is fixedly installed with hook rods 305. The first hydraulic rods 302 are used to push the second hydraulic rods 304 and hook rods 305 to rise, thereby causing the hook rods 305 to disengage from the front side of the moving extrusion frame 503, so as to facilitate the removal of the mounting base 501 and the removal of the winding stator.

[0034] The top of the stator winding machine 2 has four mounting cavities 301. The first hydraulic rod 302 is installed into the stator winding machine 2 through the mounting cavities 301. The mounting cavities 301 are designed to accommodate the first hydraulic rod 302, thereby reducing the overall space usage.

[0035] The output end of the first hydraulic rod 302 is fixedly mounted with a mounting bracket 303, and the second hydraulic rod 304 is fixedly mounted on the inner side of the mounting bracket 303. The mounting bracket 303 is used to install the second hydraulic rod 304.

[0036] In use, depending on the size of the stator to be wired, the movable pressing frame 503 moves closer to or further away from the fixed pressing frame 504 by synchronously rotating the threaded rod 507 under the action of the thread. After adjustment, the stator to be wired is placed inside the receiving groove 502 and positioned between the movable pressing frame 503 and the fixed pressing frame 504. The movable pressing frame 503 and the fixed pressing frame 504 only limit the position of the stator and do not fix it. After placement, the copper wire coil is inserted into the wire insertion holder 4. After insertion, the mounting base 501 is pulled so that it moves under the action of the support rod 505. The stator is moved so that it is fitted onto the outside of the wire insertion bracket 4. After placement, the hook rod 305 is moved by the second hydraulic rod 304 according to the size of the stator. The hook rod 305 moves to the front of the moving extrusion bracket 503. The first hydraulic rod 302 pulls the mounting bracket 303, which in turn lowers the second hydraulic rod 304 and the hook rod 305, so that the hook rod 305 is engaged with the front of the moving extrusion bracket 503. The copper wire is pushed into the stator through the wire insertion bracket 4. After the wire is inserted, the hook rod 305 is pushed up by the first hydraulic rod 302, which moves the mounting base 501 forward so that the stator can be pulled out from the outside of the wire insertion bracket 4 and removed.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
