Abstract
Description
Technical Field

[0002] The description in this section provides only background information related to the disclosure of this utility model and does not constitute prior art.
[0003] In existing motor winding processes, after the coil is wound, the wire ends often remain on the clamps or tooling. These wire ends need to be removed or collected promptly; otherwise, they not only affect subsequent processes but may also cause internal scattering, tangling, or short circuits within the equipment. Currently, this process mainly relies on manual operation, which is inefficient and inconsistent. While some methods use spring-loaded clips to hold the wire ends in place, these structures are complex to install and remove, time-consuming, and prone to fatigue wear over long-term use, leading to decreased clamping force or even damage, failing to meet the demands of high-speed automated production. Therefore, how to reliably secure and easily remove wire ends during motor winding, while preventing scattering, has become a pressing technical problem for the industry.

[0019] Please see Figure 1-4 This embodiment describes a wire cutting and clamping integrated wire cutting machine, which includes: The bracket 1 has a first end and a second end that are arranged opposite to each other along the axial direction; Cylinder 2, which is fixed to the first end of the bracket 1; The two-stage propulsion mechanism 3 includes a positioning pin 31, a first pushing block 32, an elastic element 33, and a second pushing block 34. The positioning pin 31 is fixed on the bracket 1. The first pushing block 32, the elastic element 33, and the second pushing block 34 are sequentially sleeved on the positioning pin 31 from the first end to the second end and are connected. The first end of the first pushing block 32 is connected to the piston end of the cylinder 2. The first pushing block 32 includes a first pushing surface 321 extending along the direction of the second end, and the second pushing block 34 includes a second pushing surface 341 extending along the direction of the second end. The wire-cutting mechanism 4 includes a rotating shaft 41, a wire cutter 42, and a wire clamp 43. The rotating shaft 41 is fixedly connected to the bracket 1. The wire cutter 42 includes a first rotating hole 421, and the wire clamp 43 includes a second rotating hole 431. The rotating shaft 41 passes through the first rotating hole 421 and the second rotating hole 431. The first end of the wire cutter 42 includes a first inclined surface 422 that cooperates with the first pushing surface 321, and the first end of the wire clamp 43 includes a second inclined surface 432 that cooperates with the second pushing surface 341.
[0020] Specifically, the integrated wire cutting and clamping machine includes a first station and a second station. In the first station, the piston end of the cylinder 2 presses down and pushes the first pushing block 32, the elastic element 33, and the second pushing block 34 down simultaneously. The elastic element 33 remains extended, and the second pushing surface 341 of the second pushing block 34 abuts against the second inclined surface 432. The first end of the wire clamp 43 opens, and the second end of the wire clamp 43 closes and clamps the enameled wire. In the second station, the piston end of the cylinder 2 further presses down and pushes the first pushing block 32 down. The elastic element 33 is compressed, and the first pushing surface 321 of the first pushing block 32 abuts against the first inclined surface 422. The first end of the wire cutter 42 opens, and the second end of the wire cutter 42 closes and cuts the enameled wire.
[0021] In specific operation, firstly, the operator places the corresponding enameled wire to be processed at the opening of the second end of the wire cutter 42 and the wire clamp 43, with both the second ends of the wire cutter 42 and the wire clamp 43 in an open state. Then, the operator starts the cylinder 2, and the piston at the output end of the cylinder 2 presses down, causing the first pushing block 32 in the two-stage propulsion mechanism 3 to come into contact with and be pushed, so that the first pushing block 32, the elastic element 33, and the second pushing block 34 are pressed down to the first working position. At this time, the second inclined surface 432 of the first end of the wire clamp 43 first contacts the second pushing surface 341 of the second pushing block 34 and is passively sliding on the inclined surface. Since the middle position of the wire clamp 43 is open... The shaft is connected to the bracket 1 through the second rotating hole 431. Therefore, the wire clamp 43 rotates, the first end of the wire clamp 43 opens, and the second end of the wire clamp 43 closes. The enameled wire at the second end position is clamped and fixed so that it cannot fly. Similarly, the piston at the output end of the cylinder 2 continues to press down, so that the first push block 32 is pushed to the position of the second station. At this time, since the second end of the wire clamp 43 has been closed to the maximum angle, the second push block 34 cannot be pushed down further. The first push block 32 is pushed down, and the elastic element 33 between the first push block 32 and the second push block 34 is compressed. The first end of the wire cutter 42 opens, the second end closes, and the clamped enameled wire is cut short.
[0022] In fact, the middle position of the first push block 32 and the second push block 34 can be connected by a sliding groove, which can improve the stability of the transfer between the first station and the switching between the second station.
[0023] Based on the above structure, the wire clamp 43 and wire cutter 42 in the shearing mechanism 4 can be pushed in two stages by the two-stage propulsion mechanism 3, realizing the automatic clamping and cutting process. Specifically, after the piston of the cylinder 2 is pressed down, the wire clamp 43 in the shearing mechanism 4 can be pushed first, and the wire cutter 42 in the shearing mechanism 4 can be pushed after the enameled wire is clamped, which can achieve stable wire cutting, avoid wire flying around, improve cutting quality, and achieve a high degree of automation when the two are linked.
[0024] Furthermore, the two-stage propulsion mechanism 3 also includes a first slide rail 46 and a first slide groove 47. The first slide rail 46 is fixed to one side of the first push block 32, and the first slide groove 47 is fixed to the bracket 1, extending axially. The first slide rail 46 and the first slide groove 47 are connected in a cooperative manner. Similarly, the two-stage propulsion mechanism 3 also includes a second slide rail 48 and a second slide groove 49. The second slide rail 48 is fixed to one side of the second push block 34, and the second slide groove 49 is fixed to the bracket 1, extending axially. The second slide rail 48 and the second slide groove 49 are connected in a cooperative manner. Taking the cooperation of the first slide rail 46 and the first slide groove 47 as an example, during the movement of the first push block 32 towards the second end, the first slide rail 46 and the first slide groove 47 undergo misalignment, thus limiting the movement path of the first push block 32 to a direction parallel to the axial direction, making the movement of the first push block 32 smoother and avoiding misalignment relative to the bracket 1. The principle of the second slide rail 48 and the second slide groove 49 is the same as above.
[0025] In another embodiment, the wire cutter 42 includes a pair mirror-image arranged along the axial direction, and the two wire cutters 42 are connected at one end by a first connecting spring 423; the wire clamp 43 includes a pair mirror-image arranged along the axial direction, and the two wire clamps 43 are connected at one end by a second connecting spring 433. Taking the first connecting spring 423 as an example, when the first pushing block 32 is reset, and the first inclined surface 422 at one end of the two wire cutters 42 no longer resists contact, the first connecting spring 423 tends to reset, causing the first end of the wire cutter 42 to automatically close and reset. The principle of the second connecting spring 433 is the same.
[0026] Furthermore, the wire clamp 43 has a concave-convex engagement surface 434 on the side that contacts the enameled wire. The concave-convex engagement surface 434 can enhance the friction of the contact surface and help improve the stability of the wire clamp in a limited space.
