[0025] See Figures 1-4 , the auxiliary assembly device for the armature winding coil of the large DC motor in this embodiment can automatically clamp and push the insulating pad, insert the insulating pad between the coils of the armature winding, improve work efficiency, reduce the labor intensity of the staff, and at the same time can avoid the situation of damaging the coil by hammering on the coil. In this embodiment, it mainly includes an auxiliary frame 1, and the cross-section of the auxiliary frame 1 is designed in a C-shaped structure. A handle 6 is fixedly arranged in the middle of the top end of the auxiliary frame 1. Clamping plates 2 for limiting the auxiliary frame 1 are horizontally slidably arranged on both side parts of the bottom end of the auxiliary frame 1.

[0026] The clamping mechanism 3 includes the middle part of the auxiliary frame 1 and fixing plates 31 fixedly arranged at the opposite ends of the sliding grooves 10. A left-right threaded screw 32 is rotatably arranged in the middle of the auxiliary frame 1. The left-right threaded screw 32 is a mature prior art and will not be described in detail here. Both ends of the left-right threaded screw 32 are inserted into the corresponding fixing plates 31, and both ends of the left-right threaded screw 32 are threadedly connected to the corresponding sliding plates 9. A first sprocket 33 is fixedly arranged in the middle of each left-right threaded screw 32, and a chain 34 is sleeved on the first sprocket 33. A first motor 35 is fixedly arranged in the middle of the auxiliary frame 1, and a second sprocket 36 for driving the chain 34 is arranged at the output end of the motor. A limiting plate 37 for preventing the chain 34 from falling off is fixedly arranged on the first motor 35 above the chain 34. A control module is also provided, and the first motor 35 is centrally controlled by the control module.

[0027] When the auxiliary frame 1 needs to be fixed on the coil, move the auxiliary frame 1 through the grip 6. Then insert the clamping plate 2 into the grooves on both sides of the groove where the insulating pad is about to be inserted. At this time, the magnet 11 will make the clamping plate 2 closely adhere to the deep part of the groove, so as to facilitate the fixation of the position of the auxiliary frame 1 and avoid the deviation of the front, rear, high and low of the auxiliary frame 1 when limiting the position of the auxiliary frame 1. Then control the first motor 35 to work through the control module. The first motor 35 drives the second sprocket 36 to rotate, so that the left and right hand screw rods 32 rotate through the chain 34 and the first sprocket 33, and then the corresponding sliding plates 9 slide relatively in the chute 10. At this time, the clamping plate 2 clamps the groove to realize the fixation of the auxiliary frame 1, facilitating the subsequent insertion operation of the insulating pad. At the same time, the clamping plate 2 can adapt to armature windings of different sizes and assist in assembling insulating pads for armature windings of different sizes. When the auxiliary frame 1 needs to be removed from the coil, control the first motor 35 to reverse through the control module to release the clamping of the coil by the clamping plate 2. At this time, the auxiliary frame 1 can be removed through the grip 6.

[0028] In order to automatically insert the insulating pad into the coil. Refer to Figure 2 and Figure 4 In this embodiment, a soft plate 4 for limiting the bottom end of the insulating pad is fixedly arranged on the lower side of the end of the auxiliary frame 1.

A limiting wheel 8 for limiting the top end of the insulating pad is rotatably arranged at the lower part of the support frame 7. Propelling mechanisms 5 for driving the insulating pad to move are arranged on both sides of the auxiliary frame 1 above the soft plate 4. Each propelling mechanism 5 includes adjusting plates 51 fixedly arranged on both sides of the end of the auxiliary frame 1. A displacement plate 52 is horizontally slidably arranged at the opposite end of each adjusting plate 51. An adjusting bolt 53 with its tail abutted against the displacement plate 52 is arranged through the side part of the adjusting plate 51. A second motor 54 is vertically fixedly arranged at the top end of each displacement plate 52. The second motors 54 are centrally controlled by the control module and the output shaft rotation directions of the two second motors 54 are opposite. The output end of the second motor 54 penetrates through the displacement plate 52 and a propelling wheel 55 is fixedly arranged at its end. The periphery of the propelling wheel 55 can be set to be made of a frosted material or can be sleeved with a rubber ring to increase the friction force.

[0029] After the position of the auxiliary frame 1 is fixed and the insulating pad needs to be inserted into the coil, first insert the insulating pad into the groove. At this time, the insulating pad is located between the flexible plate 4 and the limiting wheel 8, and the up-and-down direction is limited by the flexible plate 4 and the limiting wheel 8. At this time, the flexible plate 4 is in contact with the coil. Then rotate the adjusting bolt 53 to make the displacement plate 52 slide on the adjusting plate 51, so that the pushing wheel 55 is closely attached to the insulating pad. Then, the control module controls the two second motors 54 to work, and the second motors 54 drive the pushing wheels 55 to work, so that the insulating pad is inserted into the groove between the coils through the pushing wheels 55. Furthermore, the working efficiency is improved, the labor intensity of the staff is reduced, and at the same time, the situation of damaging the coil by hammering on the coil can be avoided, and different sizes of insulating pads used for different sizes of armature windings can be adapted.

[0030] The usage method of the auxiliary assembly device for the armature winding coil of the large DC motor of the present utility model: First, move the auxiliary frame 1 through the handle 6. Then insert the clamping plate 2 into the grooves on both sides of the groove where the insulating pad is about to be inserted, and use the magnet 11 to make the clamping plate 2 closely adhere to the deep part of the groove, which is convenient for fixing the position of the auxiliary frame 1 and avoiding the deviation of the front, back, high and low of the auxiliary frame 1 when limiting the auxiliary frame 1. The control module controls the first motor 35 to drive the second sprocket 36 to rotate, so that the left and right hand threads screw rod 32 rotates through the chain 34 and the first sprocket 33, and the corresponding sliding plate 9 slides relatively in the chute 10. At this time, the clamping plate 2 clamps the groove, realizing the fixation of the auxiliary frame 1, which is convenient for the subsequent insertion operation of the insulating pad. At the same time, the clamping plate 2 can adapt to different sizes of armature windings and assist in assembling insulating pads for different sizes of armature windings.

[0031] After the position of the auxiliary frame 1 is fixed and the insulating pad needs to be inserted into the coil, first insert the insulating pad into the groove. At this time, the insulating pad is located between the flexible plate 4 and the limiting wheel 8, and the up-and-down direction is limited by the flexible plate 4 and the limiting wheel 8. At this time, the flexible plate 4 is in contact with the coil. Then rotate the adjusting bolt 53 to make the displacement plate 52 slide on the adjusting plate 51, so that the pushing wheel 55 is closely attached to the insulating pad. Then, the control module controls the two second motors 54 to drive the pushing wheels 55 to work, so that the insulating pad is inserted into the groove between the coils through the pushing wheels 55. Furthermore, the working efficiency is improved, the labor intensity of the staff is reduced, and at the same time, the situation of damaging the coil by hammering on the coil can be avoided, and different sizes of insulating pads used for different sizes of armature windings can be adapted.

[0032] When the insulating pad is inserted into the coil and the auxiliary frame 1 needs to be removed from the coil, the control module controls the first motor 35 to reverse, so that the clamping plate 2 releases the clamping of the coil. At this time, the auxiliary frame 1 can be removed through the handle 6.
