[0022] like Figure 1 As shown, an auxiliary hooking mechanism for a multi-strand brushless stator internal winding machine includes a support plate 4. A first three-axis assembly 1 and a second three-axis assembly 2 are mounted on the support plate 4. The first and second three-axis assemblies 1 and 2 are installed on the left and right sides of the support plate 4, respectively, and have identical structures and are arranged obliquely symmetrically. Both the first and second three-axis assemblies 1 and 2 are equipped with hook pin rotating assemblies 3. The hook pin rotating assemblies 3 on the first three-axis assembly 1 are located above the support plate 4, while those on the second three-axis assembly 2 are located below the support plate 4, respectively responsible for the hooking work on the upper and lower stators. Compared to the traditional method where the upper and lower stators require manual operation, this mechanism clearly defines the division of labor, reduces the workload of operators, and improves winding efficiency.

[0023] like Figure 2As shown, the first three-axis assembly 1 includes a Z-axis motor 5 and an X-axis bottom plate 8, the Z-axis motor 5 is installed below the support plate 4, the X-axis bottom plate 8 is installed above the support plate 4, a lead screw 7 is arranged on the Z-axis motor 5, the lower end of the lead screw 7 is fixedly connected with the Z-axis motor 5 through a shaft coupling (not marked in the figure), the upper end of the lead screw 7 penetrates through the support plate 4 and the X-axis bottom plate 8, and is fixedly connected with the X-axis bottom plate 8. Linear bearings 9 are arranged around the X-axis bottom plate 8, guide columns 10 corresponding to the linear bearings 9 are arranged above the support plate 4, the linear bearings 9 penetrate through the guide columns 10, and the linear bearings 9 can slide up and down in the guide columns 10. The X-axis bottom plate 8 acts as a Z-axis sliding rail by penetrating through the linear bearings 9 on the support plate 4 through the guide columns 10. Therefore, when the Z-axis motor 5 starts to rotate, the up-down movement of the X-axis bottom plate 8 can be controlled, that is, the up-down movement within a certain range in the Z-axis direction is realized.

[0024] An X-axis motor 11 and an X-axis sliding rail 13 are arranged above the X-axis bottom plate 8, the X-axis motor 11 is connected with an X-axis motor base 12, an X-axis sliding plate 14 is arranged on the X-axis sliding rail 13, and the X-axis sliding plate 14 can slide on the X-axis sliding rail 13. The left side of the X-axis sliding plate 14 is connected with the X-axis motor 11 through a shaft coupling, so that when the X-axis motor 11 starts to rotate, the left-right movement of the X-axis sliding plate 14 can be controlled, that is, the left-right movement within a certain range in the X-axis direction is realized.

[0025] A module connecting plate 15 is arranged on the right side of the X-axis sliding plate 14, a Y-axis linear module 16 is arranged on the module connecting plate 15, a Y-axis sliding block 17 is arranged in the Y-axis linear module 16, the combination of each unit of the Y-axis linear module 16 realizes the reciprocating movement of the Y-axis sliding block 17 on a straight line, the positioning is accurate, that is, the forward-backward movement within a certain range in the Y-axis direction is realized. In summary, under the cooperation of the X, Y and Z three axes, the Y-axis sliding block 17 can realize arbitrary movement in the X, Y and Z three directions within a certain space range.

[0026] The hooking needle column rotating assembly 3 is installed on the Y-axis sliding block 17, so that the task of hooking the wire in a larger space range can be completed. For different specifications of stator winding, the auxiliary hooking mechanism of the present application can successfully hook the wire, the replaceable product types are more, and the adaptation range is wider.

[0027] As Figure 3As shown, the hooking needle column rotating assembly 3 is provided with a connecting block 18 and a hooking needle column 19, the connecting block 18 is fixedly connected with the Y-axis sliding block 17, the rear side of the connecting block 18 is provided with a gear 20, the connecting block 18 is of a hollow structure, a bearing (not marked in the figure) is arranged in the connecting block 18, the hooking needle column 19 is inserted into the bearing hole from front to back, and then is inserted out from the other end, the inserted end is locked and fixed by a nut 24, and then is inserted into the gear 20, and the gear 20 is pressed by a gasket 25. A gas cylinder 21 is arranged on the outer side wall of the connecting block 18, the gas cylinder 21 is connected with a rack 22, the rack 22 is engaged with the gear 20. When the gas cylinder 21 is extended or retracted, the rack 22 can move up and down, so that the gear 20 engaged with the rack 22 rotates, and the hooking needle column 19 rotates through the bearing and the gear 20. The stroke of the gas cylinder 21 is just to make the hooking needle column 19 rotate 180°, and the front end of the hooking needle column 19 is provided with a hooking needle 23 fixedly connected, which can hook the copper wire and is directly used for the work processes of hooking and unhooking.

[0028] In actual use, the stroke of the gas cylinder 21 is preset to make the hooking needle column 19 rotate 180°, and the front end of the hooking needle column 19 is provided with a hooking needle 23 fixedly connected, and the rotation of the hooking needle 23 is used to realize unhooking and loosening of the copper wire, which is more efficient and consumes less energy than the movement of the first three-axis assembly 1 and the second three-axis assembly 2. Therefore, when the inner winding machine starts to work, it must hook the wire first and then wind the wire, and the time of the hooking work directly affects the winding efficiency of the whole process, and the wire end needs to be cut after winding is completed, and the working process is complicated. The auxiliary hooking mechanism can greatly improve the winding efficiency of the inner winding machine by moving the first three-axis assembly 1 and the second three-axis assembly 2 to hook the wire on the stator and rotating the hooking needle column rotating assembly 3 by 180° to cooperate with the unhooking and loosening work. According to the shape of the stator and the winding requirement, the movement track of the Y-axis sliding block 17 in the X, Y and Z three axes can be changed to complete the task of the auxiliary hooking of the hooking needle 23, more copper wires can be arranged in the same space, so as to meet the high slot fill rate of the motor product. The winding efficiency, the number of winding turns and the high neatness can guarantee the key performance of the motor, and the degree of mechanization is high, and the types of replaceable products are more.

[0029] Therefore, the auxiliary hooking mechanism of the multi-strand wire brushless stator inner winding machine can make the degree of mechanization of the multi-strand wire brushless stator inner winding machine higher, the winding speed faster, the efficiency greatly improved, and the types of replaceable products more.
