Description

Technical Field

[0001] The utility model relates to the technical field of motor component processing, in particular to a double-sided cutting motor stator slot insulation device. Background Art

[0002] The dovetail slots used to install slot wedges in the core slots of a wind turbine semi-direct drive stator are more than 10mm lower than the inner circle of the core. After the coil is embedded in the core, the excess slot insulation paper needs to be cut off to retain a certain height as required by the product, so that it can be used for the next step. Because the slot insulation paper that needs to be cut is located in the core slot, it is difficult to operate with scissors and ordinary paper cutters. The edges of the slot insulation after cutting are irregular and wavy, which does not meet the process requirements. The existing slot insulation processing technology is to dot and hollow out the slot insulation paper where it needs to be cut. After the line is embedded, the part to be cut is manually torn off along the hollowed-out dotted line. However, in actual operation, this technology is difficult due to the strong toughness of the slot insulation paper. The tearing process is stuck and not smooth, and there are many blocky residues left after tearing, which brings difficulties to actual operation.

[0003] In view of this, this utility model is proposed. Utility Model Content

[0022] The embodiments of the present invention will be described in detail below with reference to the examples. However, those skilled in the art will understand that the following examples are only used to illustrate the present invention and should not be construed as limiting the scope of the present invention.

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0024] The following description sets forth specific details to facilitate a thorough understanding of the present invention. However, the present invention can be implemented in a variety of other ways than those described herein, and those skilled in the art may make similar generalizations without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] refer to Figure 1 and Figure 2 This embodiment proposes a double-sided cutting motor stator slot insulation device, including a handle 1, and cutting devices are symmetrically arranged on both sides of one end of the handle 1. The cutting device includes a horn knife 2, and the horn knife 2 is fixedly connected to the handle 1. A support frame 3 is arranged on the outside of the horn knife 2.

[0026] In this embodiment, a cutting device is symmetrically provided on both sides of one end of the handle 1, and the blades of the two horn knives 2 are at a 60-degree angle relative to each other. When in use, the support frame 3 on the outside of the two horn knives 2 respectively contacts two adjacent core teeth and limits them so that the blades of the two horn knives 2 enter the core slot. The support frame 3 is stuck on the core teeth and the blades of the horn knives 2 can be accurately positioned at the depth of the slot insulation to be cut. When used for stator slot insulation cutting, the blades of the two horn knives 2 are stuck on both sides of the end of the slot insulation paper in the same core slot to be cut. The support frame 3 serves as a support, and the handle 1 is pulled to drive the horn knives 2 along the tooth groove direction of the inner surface of the stator core, from one end to the other. In this process, the blades of the two horn knives 2 are tangent to the two sides of the slot insulation respectively. The slot insulation to be cut can be completely cut according to the size required by the process, and the cut surface is flat, smooth, and burr-free, meeting the process requirements at one time.

[0027] Specifically, one end of the handle 1 provided with the cutting device is provided with a bevel 101, and the horn knife 2 is fixedly connected to the bevel 101. In this embodiment, the handle and the horn knife are connected by the bevel, which is easy to install and has good stability.

[0028] Specifically, the support frame 3 is L-shaped, the horizontal plate 301 of the support frame 3 is fixedly connected to the horn knife 2 and the inclined surface 101, and the vertical plate 302 is perpendicular to the surface where the blade of the horn knife 2 is located. In this embodiment, the support frame 3 is L-shaped, which is convenient to use and easy to install, and plays a supporting role while saving more materials.

[0029] Specifically, the handle 1 is provided with a cutting device at one end and a protective head 4, one end of the protective head 4 is fixedly connected to the handle 1, and the other end is located directly above the two horn knives 2.

[0030] In this embodiment, the free end of the protective head is located directly above the head of the horn knife 2. During the process of the horn knife cutting the insulating paper, it plays a protective and guiding role to prevent the blade of the horn knife 2 from scratching other parts besides the material to be cut; at the same time, during the cutting process, the discarded strip-shaped groove insulation cut by the two blades can be guided to both sides of the protective head to avoid the two strip-shaped groove insulation cut off from being entangled, which affects the normal cutting process.

[0031] Specifically, the protective head 4 includes a straight section 401 and a curved section 402 integrally formed therewith. The straight section 401 is fixedly connected to the handle 1 , and the curved section 402 is located directly above the two ox horn knife heads 2 .

[0032] In this embodiment, the straight section 401 can facilitate the stable connection between the protective head 4 and the handle 1, and the curved section is suspended and located directly above the heads of the two horn knives 2, which can prevent the blades of the horn knives 2 from scratching other parts besides the material to be cut.

[0033] In the above embodiments, the straight section 401 of the protective head 4 is preferably fixedly connected to the handle 1 via rivets; the horn knife 2 is connected to the handle 1 via rivets, and the support frame 3 is connected to the outside of the horn knife 2 via rivets.

[0034] In the above embodiments, the handle 1 is preferably cylindrical, which is more comfortable during use.

[0035] The dimensions of the components, the distances between the components, and the angle between the two horn cutters in the above embodiments can be adjusted according to the actual working conditions of the stator and the core slots.

[0036] Although this specification has provided a detailed description of the present invention using general instructions and specific embodiments, it will be apparent to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, such modifications or improvements, without departing from the scope of the present invention, are intended to fall within the scope of protection claimed herein.
