Description

Technical Field

[0001] This utility model belongs to the field of positioning fixture technology, and particularly relates to positioning fixtures in the automated processing of winding stators. Background Technology

[0002] With the continuous development of intelligent manufacturing technology for motors, automated production lines for stator windings have gradually become widespread. However, manual operation is still required in processes such as inserting phase-spacer paper and connecting lead wires. Especially in the subsequent shaping and binding process, the mold will apply pressure to the ends of the coil, which can easily lead to the lead wire being squeezed, deformed, or damaged.

[0003] In existing technologies, a clearance structure is usually set on the mold to protect the lead wire, but the lead wire still needs to be temporarily fixed manually. This operation is cumbersome, inefficient, and prone to inaccurate positioning and loosening. Utility Model Content

[0004] This utility model addresses the problems existing in the prior art by proposing the following technical solution: The positioning fixture in the automated processing of winding stators includes an arc-shaped positioning block body with multiple round holes on its inner side and a built-in strong magnet for attracting and fixing with the stator core; a positioning boss at one end of the body can cooperate with the snap-fit ​​groove on the outer circle of the stator core to prevent tooling displacement; two long strip-shaped clearance grooves in the middle of the body for threading stator leads; and an arc-shaped hook on the outer side of the body for fixing the lead nose end to prevent the lead from scattering.

[0005] As a preferred embodiment of the above technical solution, the arc surface of the positioning block body is completely fitted with the outer circular surface of the stator core, and its curvature can be adjusted according to different specifications of stator cores.

[0006] As a preferred embodiment of the above technical solution, the clearance groove is a long strip opening with a width that matches the diameter of the lead wire, ensuring that the lead wire is not easily detached after being inserted.

[0007] As a preferred embodiment of the above technical solution, the hook is an arc-shaped curved structure located on the outside of the positioning block body, used to bend and fix the excess part of the lead wire.

[0008] As a preferred embodiment of the above technical solution, the strong magnets are evenly distributed in the circular holes on the inner side of the positioning block body.

[0009] The beneficial effects of this utility model are as follows: In this application, quick installation and disassembly are achieved through magnetic attraction. The positioning boss and the fastening slot cooperate to ensure accurate tooling position. The clearance groove and hook structure effectively constrain the position of the lead wire, preventing it from being squeezed or pulled during subsequent processing. The tooling structure is simple and highly applicable, which can greatly improve production efficiency, reduce labor intensity, and at the same time ensure the quality of lead wire products.

[0012] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0013] like Figure 1 , Figure 2 and Figure 3 As shown in this embodiment of the present invention, the positioning fixture in the automated processing of the winding stator includes an arc-shaped positioning block body. The inner side of the body has multiple circular holes 1, each containing a strong magnet. One end of the body has a positioning boss 4, used to engage with the latching groove 6 on the outer circumference of the stator core. Two clearance grooves 3 are provided in the middle of the body for threading the stator lead wire 5. A hook 2 is provided on the outer side of the body for fixing the lead wire nose. The arc surface of the positioning block body is completely fitted to the outer circumference of the stator core, and its curvature can be adjusted according to different stator core specifications. The clearance groove 3 is a long, narrow opening, the width of which matches the diameter of the lead wire 5, ensuring that the lead wire is not easily dislodged after threading. The hook 2 is an arc-shaped curved structure located on the outer side of the positioning block body 10, used to bend and fix any excess portion of the lead wire 5. Strong magnets are evenly distributed in the circular holes 1 on the inner side of the positioning block body.

[0014] First, insert the stator lead wires 5 on both sides into the clearance slots 3 of the positioning fixture. Then, attach the fixture to the outer surface of the stator core and move it slightly along the circumference until the positioning boss 4 engages with the latching slot 6 on the core surface. After the fixture and core are fully engaged, straighten the lead wires 5 downwards, bend the excess portion, and insert it into the outer hook 2 to secure the lead wires. For disassembly, simply remove the fixture; the magnetic design makes the assembly and disassembly process easy and quick.

[0015] Working principle The fixture is attached to the outer surface of the stator core by a strong inner magnet, and circumferential positioning is achieved by the cooperation of the positioning boss 4 and the core clip groove 6. After the lead wire 5 passes through the clearance groove 3, its nose end is bent and inserted into the outer hook 2, thereby effectively fixing the lead wire 5. The entire installation process requires no tools, is simple and quick to operate, and is suitable for high-frequency use in automated production lines.

[0016] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
