Description

Technical Field

[0001] The present application relates to the field of weftless belt hooping, and in particular to a weftless belt hooping tool. Background Art

[0002] The lathless belt plays a role in fixing and protecting the coil in motor manufacturing, and is crucial to the stability and safety of the motor. However, under the existing technical conditions, there are some defects in the lathless belt during the hoop process, such as the outer circle size difference and the concentricity difference, which leads to the need to re-tie the lathless belt, which not only increases the cost, but also prolongs the production cycle, so it needs to be improved. Utility Model Content

[0003] In view of the deficiencies in the prior art, the present application provides a weft-free belt tooling to solve the above problems.

[0004] A tool for making a weftless belt comprises a roller frame for mounting an armature to be processed, a first clamp is mounted on the roller frame, a positioning ring is circumferentially connected to one side of the first clamp, an edge of the positioning ring is vertically folded to form a limit ring, and the positioning ring is fixed to a rectifier disk of the armature by bolts.

[0005] By adopting the above technical solution, the concentricity and flatness of the first clamp are positioned using the outer circle and plane of the rectifier disk, thereby ensuring the side uniformity and concentricity of the wound latitude-free belt, thereby ensuring that the latitude-free belt is formed in one step, reducing rework and ensuring the production cycle.

[0006] Optionally, a silicone oil layer is circumferentially arranged on a side of the limiting ring away from the positioning ring.

[0007] By adopting the above technical solution, the silicone oil layer ensures that the weft-free belt and the tooling will not stick together during demoulding.

[0008] Optionally, it also includes a second hoop, which surrounds the outer side wall of the armature to be processed.

[0009] Optionally, a demoulding layer is provided on the inner side wall of the second clamp along the circumferential direction.

[0010] By adopting the above technical solution, the demoulding layer forms an isolation film on the outer surface of the non-weft belt, so that the solidified non-weft belt can be smoothly peeled off from the tooling without destroying the structural integrity of the non-weft belt.

[0011] Optionally, the circumferential inner wall of the second clamp abuts against the circumferential outer wall of the limiting ring.

[0012] By adopting the above technical solution, the second clamp abuts against the circumferential outer side wall of the limiting ring, thereby ensuring that the outer circle of the non-weft belt is concentric with the armature.

[0013] Optionally, it further includes a third hoop and a fourth hoop, both of which are used to be installed on the armature to be processed.

[0014] In summary, the present application includes at least one of the following beneficial technical effects:

[0015] 1. Utilize the outer circle and plane of the rectifying disk to position the concentricity and flatness of the first hoop, thereby ensuring the neatness and concentricity of the side surface of the wound non-metallic belt, and further ensuring the one-time forming of the non-metallic belt, reducing rework, and guaranteeing the production cycle.

[0016] 2. The silicone oil layer ensures that the non-metallic belt and the tooling will not stick together during demolding.

[0017] 3. The demolding layer forms an isolation film on the outer surface of the non-metallic belt, enabling the cured non-metallic belt to be smoothly peeled off from the tooling without damaging the structural integrity of the non-metallic belt. Description of the Drawings

[0021] To facilitate the understanding of the present application, the present application will be described in more detail below in conjunction with the drawings and specific embodiments. It should be noted that when an element is expressed as "fixed to" another element, it can be directly on the other element, or there can be one or more intermediate elements therebetween. When an element is expressed as "connected to" another element, it can be directly connected to the other element, or there can be one or more intermediate elements therebetween. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this specification are only for the purpose of illustration.

[0022] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by those skilled in the technical field to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing specific embodiments and are not used to limit the present application. The term "and / or" used in this specification includes any and all combinations of one or more of the related listed items.

[0023] An embodiment of the present application discloses a tooling for winding non-metallic belts. Refer to Figure 1, including a roller stand 1 for installing the armature to be processed, a first hoop 2, a second hoop 3, a third hoop 5 and a fourth hoop 6. The first hoop 2, the second hoop 3 and the third hoop 5 are installed at the left end of the armature, and the fourth hoop 6 is installed at the right end of the armature. On one side of the first hoop 2, a positioning ring 21 is circumferentially connected. The edge of the positioning ring 21 is vertically folded to form a limiting ring 22. The positioning ring 21 is fixed on the commutator disk of the armature by bolts. The first hoop 2 has an upper and lower joint surface structure. The concentricity and flatness of the first hoop 2 are positioned by the outer circle and plane of the commutator disk, so as to ensure the side neatness and concentricity of the wound non-metallic belt, and further ensure the one-time forming of the non-metallic belt, reduce rework and ensure the production cycle.

[0024] Refer to Figure 1 , on the side of the limiting ring 22 away from the positioning ring 21, a silicone oil layer is circumferentially coated. After the limiting ring 22 is installed, a silicone oil layer is applied on one side of the limiting ring 22 to ensure that the non-metallic belt and the tooling will not stick together when demolding.

[0025] Refer to Figure 1 , the second hoop 3 and the third hoop 5 surround the side wall. The circumferential inner side wall of the second hoop 3 abuts against the circumferential outer side wall of the limiting ring 22. A demolding layer 4 is circumferentially arranged on the inner side wall of the second hoop 3, and the demolding layer 4 is a demolding tape. After the non-metallic belt is wound, the demolding tape is wound on the outside of the non-metallic belt, and then the second hoop 3 is installed. The demolding layer 4 forms an isolation film on the outer surface of the non-metallic belt, so that the cured non-metallic belt can be smoothly peeled off from the second hoop 3 without damaging the structural integrity of the non-metallic belt. After the second hoop 3 abuts against the circumferential outer side wall of the limiting ring 22, the outer circle of the non-metallic belt is ensured to be concentric with the armature.

[0026] Refer to Figure 1 , when the non-metallic belt is wound well at the right end of the armature, the demolding tape is wound on the outside of the non-metallic belt, and then the fourth hoop 6 is installed on the outside of the demolding tape, so as to ensure that the outer circle of the non-metallic belt is concentric with the armature.

[0027] The implementation principle of a non-metallic belt winding tooling in an embodiment of the present application is: the concentricity and flatness of the first hoop 2 are positioned by the outer circle and plane of the commutator disk, so as to ensure the side neatness and concentricity of the wound non-metallic belt, and further ensure the one-time forming of the non-metallic belt, reduce rework and ensure the production cycle.

[0028] The above are all preferred embodiments of the present application. The protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
