Abstract
Description
Technical Field
[0001] This application relates to the field of wiring tooling technology, and in particular to a wiring tooling for a winding stator and a winding stator system. Background Technology
[0002] To meet various performance requirements, new high-end motors, such as those used in new energy vehicles, have more complex structures and involve more diverse production processes.
[0003] Typically, motors are wired manually. However, due to the large number and close arrangement of copper wires required for stator products, manual wire insertion is inefficient. The copper wires are deformable and elastic, resulting in uneven wire shapes and outward expansion after insertion. This outward expansion poses a risk of falling out, significantly impacting subsequent processes. Utility Model Content
[0004] This application provides a winding stator insertion tool and a winding stator system to improve the efficiency of stator insertion.
[0005] The embodiments of this application adopt the following technical solutions:
[0006] In a first aspect, embodiments of this application provide a wire insertion fixture for a winding stator, wherein the wire insertion fixture includes: a column (10), a hook tooth (9), a movable cover plate (12), a movable pressure plate (13), and a threaded sleeve (14). The column (10) is sleeved with the threaded sleeve (14). The threaded sleeve (14) and the movable pressure plate (13) together drive the movable cover plate (12) to move horizontally downward while the hook tooth (9) rotates upward. When the threaded sleeve (14) moves to the limit position of the column (10), the tail end face of the hook tooth (9) is parallel to the end face of the winding stator to be inserted.
[0007] In some embodiments, the arcuate surface of the movable cover plate (12) and the hook tooth (9) form a cam structure.
[0008] In some embodiments, the tail of the hook tooth (9) rotates around the hook tooth positioning pin (11).
[0009] In some embodiments, the hook teeth (9) are disposed on the hook base (8).
[0010] In some embodiments, it further includes a support tube (7) that abuts against the hook ruler base (8).
[0011] In some embodiments, the system further includes a crossed roller bearing (4), a stator tray (5), and a bearing inner ring connecting plate (6), wherein the stator tray (5) is connected to the crossed roller bearing (4) via the bearing inner ring connecting plate (6).
[0012] In some embodiments, the movable cover plate (12) is movably connected to the hook teeth (9).
[0013] In some embodiments, the hook teeth (9) are symmetrically arranged along the movable cover plate (12).
[0014] In some embodiments, the hook teeth (9) are pre-set with hook grooves.
[0015] Secondly, embodiments of this application also provide a winding stator system, which includes the insertion tool described in the first aspect.
[0016] The above-mentioned technical solution adopted in the embodiments of this application can achieve the following beneficial effects: The wire insertion fixture includes: a column (10), a hook tooth (9), a movable cover plate (12), a movable pressure plate (13), and a threaded sleeve (14). The column (10) is sleeved with the threaded sleeve (14). The threaded sleeve (14) and the movable pressure plate (13) together drive the movable cover plate (12) to move horizontally downwards, while the hook tooth (9) rotates and moves upwards. When the threaded sleeve (14) moves to the limit position of the column (10), the end face of the hook tooth (9) is parallel to the end face of the stator of the winding to be inserted. Through the above structure, an automated wire insertion fixture is provided. At the same time, it can ensure that all copper wires are at the same height during wire insertion and avoid the phenomenon of the copper wires expanding outwards. Attached Figure Description

Detailed Implementation
[0026] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0027] In related technologies, manually inserting the wires directly into the stator core slots cannot guarantee that the copper wires are at the same height, resulting in inconsistent insertion depths and outward expansion of the copper wires. This has at least the following drawbacks:
[0028] (1) When inserting the hairpin, the copper wire is prone to expansion due to deformation and elasticity, which is not conducive to the next production process. (2) If the hairpin copper wire is inserted manually without tooling, it is impossible to ensure that the depth of insertion of the hairpin copper wire into the stator core is consistent and at the same height, resulting in poor product consistency.
[0029] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.
[0030] This application provides a wiring fixture for a winding stator, such as... Figure 2The diagram shows a cross-sectional view of the insertion fixture for the winding stator in this embodiment of the application. The insertion fixture includes: a column 10, a hook tooth 9, a movable cover plate 12, a movable pressure plate 13, and a threaded sleeve 14. The column 10 is sleeved with the threaded sleeve 14. The threaded sleeve 14 and the movable pressure plate 13 together move the movable cover plate 12 horizontally downwards while the hook tooth 9 rotates upwards. When the threaded sleeve 14 moves to the limit position of the column 10, the tail end face of the hook tooth 9 is parallel to the end face of the winding stator to be inserted. The column 10 is sleeved with the threaded sleeve 14. During insertion, the threaded sleeve 14 and the movable pressure plate 13 together move the movable cover plate 12 horizontally downwards while the hook tooth 9 rotates upwards. This ensures that the copper wire does not expand outwards during insertion, does not affect the next process, and improves product quality and production efficiency.
[0031] like Figure 2 As shown, when the threaded sleeve 14 moves to the limit position of the column 10, the tail end face of the hook tooth 9 is parallel to the end face of the stator of the winding to be inserted, which can ensure that all copper wires are at the same height when inserting wires, ensure that the wires are arranged neatly, and improve the wire insertion efficiency.
[0032] When inserting the wire, a common tool is used to rotate the threaded sleeve 14 clockwise. During rotation, the threaded sleeve 14 and the movable pressure cap 13 move the movable cover plate 12 downwards. The arc surface of the movable cover plate 12 and the hook tooth 9 form a cam mechanism. The movable cover plate 12 moves downwards counterclockwise with the threaded sleeve 14. The tail of the hook tooth 9 rotates upwards around the hook tooth positioning pin 11. The threaded sleeve 14 rotates to the hard limit position of the column 10, and the tail end face of the hook tooth 9 is parallel to the upper end face of the product to be inserted. At this time, the copper wire can be inserted. Figure 7 The diagram shown is a schematic of the winding stator after the wiring fixture has completed the wiring process.
[0033] like Figure 3 The image shows the insertion fixture for the uninserted winding stator. The specific workflow includes: the preceding equipment places the stator core onto the insertion fixture → the insertion fixture and the product are transferred together to the insertion point → a hexagonal wrench is used to rotate clockwise within the threaded sleeve → rotated to the hard limit position → at this point, the hook teeth rise to the working position → insertion is performed as follows. Figure 2 The winding stator winding tool shown in the diagram → After inserting the wire, rotate the threaded sleeve counterclockwise → The hook teeth return to their original position.
[0034] By using the insertion tool in this embodiment, not only can the copper wires of the hairpin be at the same height, but the problem of wire expansion is also solved, ensuring accurate manual insertion and product consistency.
[0035] In one embodiment of this application, the arcuate surface of the movable cover plate 12 and the hook tooth 9 form a cam structure.
[0036] like Figure 4 and Figure 5 As shown, the arc surface on the movable cover plate 12 and the hook tooth 9 together form a cam structure, which can bring the copper wire to the same height position when inserting the wire.
[0037] In one embodiment of this application, the tail of the hook tooth 9 rotates around the hook tooth positioning pin 11.
[0038] like Figure 3 As shown, since the hook tooth 9 is rotatable, the tail of the hook tooth 9 can rotate around the hook tooth positioning pin 11, thereby meeting the tightening action requirement when inserting the wire.
[0039] In one embodiment of this application, the hook teeth 9 are disposed on the hook ruler base 8.
[0040] like Figure 6 As shown, the hook base 8 is provided with hook teeth 9 on the left and right sides respectively, which can ensure that the copper wire does not expand outward when inserting the wire.
[0041] In one embodiment of this application, it further includes a support tube 7, which abuts against the hook ruler base 8.
[0042] like Figure 1 As shown, the support tube 7 is configured to abut against the hook base 8, thereby meeting different strength requirements.
[0043] In one embodiment of this application, the system further includes a crossed roller bearing 4, a stator tray 5, and a bearing inner ring connecting plate 6, wherein the stator tray 5 is connected to the crossed roller bearing 4 via the bearing inner ring connecting plate 6.
[0044] The crossed roller bearing 4 is connected to the inner ring connecting plate 6 of the bearing and then to the stator tray 5.
[0045] In one embodiment of this application, the movable cover plate 12 is movably connected to the hook tooth 9.
[0046] In one embodiment of this application, such as Figure 4 and 5 As shown, after forming the convex structure, it facilitates movement and ensures that all copper wires remain at the same height when plugging in.
[0047] In one embodiment of this application, the hook teeth 9 are symmetrically arranged along the movable cover plate 12.
[0048] like Figure 4 and5 As shown, the hook teeth 9 are symmetrically arranged along the movable cover plate 12, taking into account the motor to be wired, so that the copper wire on the motor can be wound according to the preset requirements.
[0049] In one embodiment of this application, the hook tooth 9 is pre-set with a hook line groove.
[0050] like Figure 6 As shown, in Figure 6 The 'a' or 'b' indicates the wire hook groove, which helps to secure the copper wire when inserting it.
[0051] This application embodiment also provides a winding stator system, which includes the aforementioned insertion tool. The insertion tool includes: a column 10, a hook tooth 9, a movable cover plate 12, a movable pressure plate 13, and a threaded sleeve 14. The column 10 is sleeved with the threaded sleeve 14. The threaded sleeve 14 and the movable pressure plate 13 together drive the movable cover plate 12 to move horizontally downward while the hook tooth 9 rotates and moves upward. When the threaded sleeve 14 moves to the limit position of the column 10, the tail end face of the hook tooth 9 is parallel to the end face of the winding stator to be inserted.
[0052] The above description is merely an embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
