Description

Technical Field

[0001] This utility model belongs to the technical field of flat wire stator manufacturing tooling, specifically relating to a stator three-phase copper busbar positioning tooling. Background Technology

[0002] The existing motor positioning device consists of two parts: a stator positioning device and a copper busbar positioning device. During welding, the three-phase copper busbars are placed on the copper busbar positioning fixture for positioning. After the copper busbars are installed, the outer circle of the stator is placed in the stator positioning device, and the stator position is manually adjusted so that the leads overlap with the areas to be welded on the three-phase copper busbars for welding. Because this fixture is a split type, it cannot effectively control the relative positions between the three-phase copper busbars and their positions on the stator. This can easily lead to misalignment between the terminal block holes and the three-phase copper busbar holes during subsequent terminal block installation, making terminal block installation difficult. The copper busbars must be manually bent for position adjustment during installation, which can easily damage the weld joints. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a stator three-phase copper busbar positioning fixture.

[0004] The technical solution of this utility model is as follows: A stator three-phase copper busbar positioning fixture includes a lower end face positioning plate and an upper end face positioning plate that is coaxially and detachably connected to the lower end face positioning plate. A contour plate is provided on the side of the upper end face positioning plate away from the lower end face positioning plate, and the contour plate has a circular hole for fixing the three-phase copper busbar. The lower end face positioning plate is provided with a positioning key that can be inserted into the stator keyway.

[0005] Furthermore, the contour plate is fixed to the upper end face positioning plate by a Z-shaped bracket.

[0006] Furthermore, the upper end face positioning plate and the lower end face positioning plate are connected by a locking mechanism.

[0007] Furthermore, the upper end face positioning plate is provided with a positioning rod, and the lower end face positioning plate is provided with a positioning hole for the positioning rod to be inserted.

[0008] Compared with the prior art, the beneficial effects of this utility model are: This utility model uses a contour plate and circular holes to fix the three-phase copper busbars, thereby achieving the positioning of the three-phase copper busbars. Then, the upper and lower end face positioning plates are used to achieve the positioning of the stator axis. Finally, the positioning key is used to achieve the circumferential positioning of the stator, thereby achieving precise positioning of the relative position of the three-phase copper busbars and their position on the stator, avoiding the risk of bending and welding breakage due to inaccurate positioning during subsequent installation of terminal blocks.

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] like Figures 1 to 5 As shown, a stator three-phase copper busbar positioning fixture includes a lower end face positioning plate 7 and an upper end face positioning plate 4 that is coaxially and detachably connected to the lower end face positioning plate 7. A contour plate 2 is provided on the side of the upper end face positioning plate 4 away from the lower end face positioning plate 7, and a round hole 5 for fixing the three-phase copper busbar is opened on the side of the contour plate 2.

[0013] The lower end face positioning plate 7 is provided with a positioning key 8 that can be inserted into the stator keyway; The contour plate 2 is fixed to the upper end positioning plate 4 by two Z-shaped brackets 3.

[0014] It should be noted that the lower end face positioning plate 7 and the upper end face positioning plate 4 are detachably coaxially connected through the following structure: The upper end positioning plate 4 and the lower end positioning plate 7 are connected by a latch 6. The upper end positioning plate 4 is provided with a positioning rod 9, and the lower end positioning plate 7 is provided with a positioning hole for the positioning rod 9 to be inserted.

[0015] There are at least two latches 6, which are mirror images of the meridian of the positioning plate. If there are multiple latches, they are arranged in a circular array with the center of the positioning plate 7 on the lower end face as the axis. The axial limit is achieved by setting the latches 6, and the axis positioning is achieved by setting the positioning rod 9 and the positioning hole, thereby ensuring positioning.

[0016] In use, the threaded holes 1 of the three three-phase copper busbars are fixed in the round holes 5 of the profile plate 2 with screws to ensure their relative positions. The lower end face positioning plate 7 is installed on the stator welding end, and the positioning key 8 is inserted into the keyway of the stator core to achieve angular positioning of the stator core. The lower end face positioning plate 7 and the upper end face positioning plate 4 are positioned by three guide posts to prevent circumferential displacement. The upper end face positioning plate 4 and the lower end face positioning plate 7 are overlapped and tightened by the locking buckle 6 to ensure that there is no axial movement. The outer circle of the stator is wrapped by the upper end face positioning plate 4 and the lower end face positioning plate 7. The Z-shaped bracket 3 is installed on the upper end face positioning plate 4. The Z-shaped bracket 3 can determine the welding height of the three-phase copper busbars. The profile plate 2 is connected to the Z-shaped bracket 3, so the entire fixture becomes a whole, which can determine the relative position of the three-phase copper busbars and their position on the stator. When the stator with the tooling installed is placed on the stator positioning device of the equipment and rolled, the stator will also roll along with the tooling under the action of positioning key 8. In this way, the position of the copper busbar and the stator remains unchanged, ensuring positioning.

[0017] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features; any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
