DETAILED DESCRIPTION

[0019] The technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings.

[0020] Example 1

[0021] like Figure 1-5 As shown, a motor stator core block winding tool includes a tool basic component 1 and a tool extension component 2, the tool basic component 1 is provided with a winding machine connection interface 10102 connected to the winding machine and a fixed interface for connecting and fixing a core block 3, two opposite sides of the tool extension component 2 are each provided with a fixed interface of a core block 3, the tool extension component 2 is connected to a core block 3 through one of the fixed interfaces of the core block 3, and is connected and fixed to the fixed interface of the tool basic component 1 through the core block 3, the other fixed interface of the tool extension component 2 is connected to another core block 3, and is connected to another tool extension component 2 through the core block 3, and multiple tool extension components 2 can be connected in series according to this connection method to complete the winding of multiple core blocks 3.

[0022] In order to realize the connection and fixation of the core block 3 by the tooling basic component 1, the tooling basic component 1 includes a basic body 101 and a basic pressing block 102. The fixing interface is a first side slot structure 10101 matched with the tooth portion of the core block 3, which is set on one side of the basic body 101. The first side slot structure 10101 is open at the upper end and closed at the lower end. The basic pressing block 102 is located at the upper end of the basic body 101 and is detachable. After the core block 3 is inserted into the first side slot structure 10101 from top to bottom, the basic pressing block 102 presses the tooth portion of the core block 3 from above and fixes it. The connection and fixation of the core block 3 can be conveniently realized. After connecting the winding machine through the winding machine interface, the winding of a single core block 3 can be realized.

[0023] In order to realize the connection and fixation of the core block 3 by the tooling extension component 2, the tooling extension component 2 includes an extension body 201 and an extension pressing block 202. The fixing interface is a second side slot structure 20101 matched with the teeth of the core block 3, which is arranged on two opposite sides of the extension body 201. The second side slot structure 20101 is open at the upper end and closed at the lower end. The extension pressing block 202 is located at the upper end of the extension body 201 and is detachable. After the core blocks 3 on both sides are inserted into the second side slot structure 20101 from top to bottom, the extension pressing block 202 presses the teeth of the two core blocks 3 from above and fixes them. It is convenient to realize the connection and fixation of two core blocks 3 at the same time, and realize the winding of multiple core blocks 3 after one of the core blocks 3 is connected to the tooling basic component 1, and realize the connection and fixation of more core blocks 3 and the extension body 201 by connecting the core blocks 3 and the extension body 201 in series, and realize the winding of more core blocks 3.

[0024] In order to pass the copper wire of the previous iron core block 3 after winding to the next iron core block 3 for winding, two opposite sides of the extension body 201 are each provided with a wire groove 20102, the wire groove 20102 is located on both sides of the serial connection direction of the iron core blocks 3, the direction of the wire groove 20102 is parallel to the serial connection direction of the tooling extension assembly 2, and the wire groove 20102 runs through the extension body 201 in the serial connection direction of the tooling extension assembly 2. The copper wire of the previous iron core block 3 after winding can be passed through the wire groove 20102 to wind the next iron core block 3.

[0025] In order to facilitate processing, both the tooling basic component 1 and the tooling extension component 2 are rectangular structures. The shape is simple and easy to process.

[0026] In order to achieve firm fixation of the core block 3, the basic pressing block 102 is detachably connected and fixed to the basic body 101 by bolts, and the extended pressing block 202 is detachably connected and fixed to the extended body 201 by bolts. The bolts are fastened firmly and reliably.

[0027] In order to avoid damage to the wire during winding, the edges and corners of the tooling basic component 1 and the tooling extension component 2 are all rounded. The edges and corners avoid damage to the wire during winding, thereby improving safety.

[0028] Before winding, firstly, the basic body 101 of the tooling basic component 1 is connected and fixed to the winding machine through the winding machine connection interface 10102, and then one end of each of the two core blocks 3 is inserted from top to bottom into the second side groove structure 20101 of the extended body 2012 of the tooling extension component 2, and then the two core blocks 3 are tightened with bolts on the extended pressing block 202, and the other end of one of the core blocks 3 is inserted from top to bottom into the first side groove structure 10101 of the basic body 101 on the winding machine, and then the two core blocks 3 are tightened with bolts on the extended pressing block 202. The basic pressing block 102 is fastened and fixed on the basic main body 101, and the other end of another core block 3 can be connected in series with the extended main body 201 and the core block 3 in sequence according to actual needs, and then fastened with the extended pressing block 202 and bolts, so as to facilitate the winding of multiple core blocks 3. After the winding of the previous core block 3 is completed, the copper wire can be passed to the next core block 3 through the wire groove 20102 for winding, so that the winding machine is effectively used to realize the winding of the yokeless block stator core, thereby improving the winding efficiency of the core block 3.

[0029] In this example, the first side groove structure 10101 and the second side groove structure 20101 are dovetail groove structures. The dovetail groove structure is widely used in the core block 3 of the disc motor, and the shapes match.
