DETAILED DESCRIPTION

[0024] The following will be described in detail in combination with the accompanying drawings. Figures 1-3 The application is further described in detail.

[0025] The application discloses a set of copper wire winding mold.

[0026] Referring to Figure 1 , Figure 2 and Figure 3 , the set of copper wire winding mold comprises a template set and a connecting plate 2.

[0027] The connecting plate 2 is fixedly installed with an ear seat 23 at each of the left and right edges at the top end, and the connecting plate 2 is fixed on a fixed device through the ear seat 23. A plurality of grooves 21 and a strip-shaped hole 22 are provided, the projection of the grooves 21 on the horizontal plane and the projection of the strip-shaped hole 22 on the horizontal plane are perpendicular to each other, two T-shaped rods 3 are installed on the connecting plate 2, the horizontal ends of the two T-shaped rods 3 are respectively placed in the two grooves 21, the vertical end of the T-shaped rod 3 vertically penetrates the strip-shaped hole 22, the vertical end of the T-shaped rod 3 is threadedly installed with a second nut 31, the second nut 31 is located below the connecting plate 2, and the top end of the second nut 31 abuts against the bottom end of the connecting plate 2, the vertical end of the T-shaped rod 3 is fixedly installed with a U-shaped threaded rod 4, and the two ends of the U-shaped threaded rod 4 are respectively installed with a first nut 41. It should be noted that the second nut 31 is provided to enhance the connectivity of the T-shaped rod 3 and the connecting plate 2.

[0028] When it is needed to move the two T-shaped rods 3 towards each other or oppositely, the worker reversely rotates the second nut 31, so that the second nut 31 does not abut against the connecting plate 2, then the T-shaped rod 3 is pulled upwards, so that the horizontal end of the T-shaped rod 3 is separated from the connecting plate 2, and finally the T-shaped rods 3 can be moved towards each other or oppositely.

[0029] The template group is provided with two groups, one template group includes a plurality of templates 1, the templates 1 are placed in sequence from top to bottom, the top end of the template 1 is fixedly installed with an auxiliary plate 11, the bottom end of the template 1 is fixedly installed with a boss 12, the sidewall of the boss 12 of the upper template 1 abuts against the sidewall bottom end of the auxiliary plate 11 of the lower template 1, two connecting holes 13 are vertically formed in one template 1, the two ends of the U-shaped threaded rod 4 pass through the connecting holes 13 on the templates 1 in the same group from top to bottom and are fixed by the first nut 41. It should be known that due to the setting of the boss 12 and the auxiliary plate 11, there is a winding space between the upper and lower adjacent two templates 1, so that the copper wire is wound on the two bosses 12 in the same plane, which can improve the stability of the copper wire winding; a plurality of templates 1 are provided, and after the winding space between the upper adjacent two templates 1 is fully wound by the copper wire, the copper wire can be directly wound in the winding space between the lower adjacent two templates 1.

[0030] As can be seen from the above, due to the setting of the strip-shaped hole 22, the T-shaped rod 3 can move towards or away from each other, and then after the two template groups are respectively installed on the two U-shaped threaded rods 4, the T-shaped rod 3 can drive the two template groups to move towards or away from each other, control the radius size of the copper wire winding, and when different equipment is maintained, the entire mold does not need to be replaced, thereby improving the maintenance efficiency of the motor.

[0031] During the rotation and fixing process of the first nut 41, if the number of rotations of the first nut 41 is too much, the one end of the template 1 provided with the connecting hole 13 will be close to each other, causing the other end of the template 1 to separate from each other, and if the number of rotations of the first nut 41 is less, the templates 1 will separate from each other, therefore, in order to ensure the stability between the templates 1, the one end of the boss 12 close to the auxiliary plate 11 is provided with a receiving groove 121, the receiving groove 121 is fixedly installed with a reset spring 123 at the groove bottom, the one end of the reset spring 123 away from the groove bottom is fixedly installed with a fixed block 122, the auxiliary plate 11 is horizontally provided with an auxiliary hole 111 corresponding to the receiving groove 121, the one end of the fixed block 122 away from the reset spring 123 is inserted into the corresponding auxiliary hole 111, and the setting of the fixed block 122 can strengthen the connectivity of the boss 12 and the auxiliary plate 11, thereby strengthening the connectivity and stability of the upper and lower adjacent two templates 1. It should be known that 1 / 3 of the length of the fixed block 122 is located in the auxiliary hole 111, and 2 / 3 of the length of the fixed block 122 is located in the receiving groove 121, so that during the rotation of the first nut 41, if the number of rotations of the first nut 41 is too much, the templates 1 will not separate from each other.

[0032] In order to facilitate the installation of the template 1 on the U-shaped threaded rod 4, the end of the fixing block 122 away from the reset spring 123 is inclined downward, the lower template 1 is moved upward, the two ends of the U-shaped threaded rod 4 pass through the connecting hole 13 of the lower template 1, then the lower template 1 is continuously moved upward, the inclined end of the fixing block 122 of the upper template 1 is subjected to a force towards the inside of the accommodating groove 121 by the auxiliary plate 11 of the lower template 1, the fixing block 122 is moved towards the inside of the accommodating groove 121 and the reset spring 123 is compressed, then the lower template 1 is continuously moved upward until the auxiliary hole 111 on the auxiliary plate 11 of the lower template 1 corresponds to the accommodating groove 121, the reset spring 123 is reset, the fixing block 122 is slid into the auxiliary hole 111 by the reset spring 123, and the whole template 1 does not need to be disassembled, thereby achieving the effect of saving labor.

[0033] In order to facilitate the disassembly of the template 1 on the U-shaped threaded rod 4, the auxiliary rod 112 is slidably installed in the auxiliary hole 111, one end of the auxiliary rod 112 abuts against the fixing block 122, and the other end is fixedly installed with the baffle 114. The auxiliary spring 113 is fixedly installed on the end of the auxiliary plate 11 away from the corresponding boss 12, the auxiliary spring 113 is sleeved on the auxiliary rod 112, one end of the auxiliary spring 113 is fixedly connected with the auxiliary plate 11, and the other end is fixedly connected with the baffle 114. When the lower template 1 needs to be disassembled, the worker presses the baffle 114, the baffle 114 drives the auxiliary rod 112 to slide towards the inside of the auxiliary hole 111, and then the auxiliary rod 112 drives the fixing block 122 to slide towards the outside of the auxiliary hole 111, after the fixing block 122 is completely slid out of the auxiliary hole 111, the worker moves the lower template 1 downward until the lower template 1 is slid out of the U-shaped threaded rod 4.

[0034] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape, principle of the present application should be covered within the protection scope of the present application.
