The present invention will be further described with reference to the accompanying drawings. A flat wire motor armature winding end twist protection assembly as shown in figures 2-5. Which comprises a base 1, a dial seat 2 arranged on the base 1 and a dial 3.
As shown in fig. 5, the dial seat 2 is an annular disc, a plurality of limit blocks 21 are uniformly arranged in the circumferential direction of the dial seat, and a groove extending along the radial direction of the dial seat is formed between adjacent limit blocks for installing the contact pin 22, so that the contact pin 22 can move along the radial direction of the dial seat 2 in the groove. The outer circumference of the dial plate seat 2 is provided with a raised annular step 23, the end part of the limiting block close to the circle center of the dial plate seat is provided with a raised limiting part 211, and the limiting parts of the limiting blocks form an annular array. The dial 3 is an annular disc and is confined between the annular array and the annular step 23 such that the dial 3 is coaxially mounted on the dial seat 2 and is rotatable relative to the dial seat 2.
As shown in fig. 2 to 3, a plurality of sliding grooves 31 are uniformly formed in the dial 3 in the circumferential direction, and pin guides 32 are installed in the sliding grooves 31. In this embodiment, the slide groove 31 is a linear groove and has an angle with the radial direction of the dial 3, and the pin guide 32 is a cylindrical pin installed in the slide groove. The pin 22 as shown in fig. 4 comprises a pin body provided with a first pin 221 and a second pin 222, and a clamping part is formed between the first pin 221 and the second pin 222 for clamping the root of the straight part of the U-shaped wire of the winding. The clamping part of the contact pin 22 is installed on the dial plate base 2 towards the center of the dial plate base 2, the other end of the contact pin main body opposite to the clamping part is provided with a connecting hole 223, and the contact pin guide 32 in the sliding groove 31 is inserted into the connecting hole 223 to connect the contact pin 22, so that the contact pin can be driven to move through the contact pin guide 32. In this embodiment, both pins of the pin 22 are chamfered in order to prevent damage to the paint film and to limit the pin's dial seat in cooperation with the dial.
The dial 3 can be rotated by manual force application or by air cylinder. In this embodiment, the cylinder 4 is fixed on one side of the base 1 through the fixing seat 5, and a piston rod of the cylinder is connected with the shift lever 6. One side of the annular step 23 close to the cylinder is provided with a rotation notch 231, the other end of the shift lever 6 penetrates through the rotation notch 231 and is fixed on the outer circumference of the dial plate 3, and when a piston rod of the cylinder 4 stretches out and draws back, the shift lever 6 can be driven to move back and forth, so that the dial plate 3 is driven to do circular motion with a limited angle.
The method for using the protective assembly of the present invention is described below by taking the winding bending of the armature of the 72-slot flat-wire motor as an example, and hereinafter, the armature of the 72-slot flat-wire motor is only described as an armature, and the 72-slot stator core is only described as a stator core.
First, the armature is explained in which the stator core has core slots radially arranged in the circumferential direction, and the core slots are rectangular. The insulation paper 9 is formed into a shape matched with the stator core slot and inserted into the stator core slot, the length of the insulation paper 9 is approximately 6mm longer than the depth of the stator core slot, and two ends of the insulation paper 9 are approximately 3mm higher than the end face of the stator core. The straight line parts of the U-shaped lines are inserted into the insulating paper 9, and the outgoing lines are arranged on the lower end surface 8 of the stator core and are not directly contacted with the 72-slot stator core, so that the insulating effect is achieved. The U-shaped wire is assembled with the insulating paper and the 72-slot stator core to form a winding (as shown in fig. 1) having linear portions arranged approximately in order, and the contact portion between the linear portion and the higher portion of the insulating paper is a linear portion root portion 10.
After the armature is manually or mechanically fed, the lower end surface 8 of the stator core is superposed with the plane where the bottom surface of the contact pin is located, so that the stator core is positioned. When the cylinder 4 is further started, the piston rod is pushed out outwards, the shift lever 6 is driven to move forwards, the shift lever 6 is fixed on the outer circumference of the drive plate 3, the drive plate 3 is driven to do limited-angle circular motion, and when the stroke of the cylinder 4 reaches a limited value, the piston rod of the cylinder 4 stops moving almost synchronously. The connecting hole 223 on the pin 22 is connected with the pin guide 32 in the sliding slot 31 of the dial 3, and the depth of the pin 22 inserted into the end of the winding linear part can be regulated and controlled by the pin guide 32.
When the piston rod stroke of the cylinder 4 is 0, the pin guide 32 is located at the end of the sliding groove 31 (as shown in fig. 2), and the corresponding pin 22 is located at the bottom of the groove formed between the limiting blocks (the end away from the center of the dial plate base 2). When the piston rod stroke of the cylinder 4 reaches the limit, the pin guide 32 is located at the top end of the sliding groove 31 (as shown in fig. 3), and the corresponding pin 22 is located at the front end (the end close to the circle center of the dial plate base 2) of the groove formed between the limit blocks, so that the clamping part of the pin 22 extends out of the groove. At this time, the first pin angle 221 and the second pin 222 of the pin 22 just stick to the insulating paper 9 and penetrate through the root 10 of the straight line part, and the root 10 of the straight line part is clamped tightly, so that the root 10 of the straight line part is fixed with the insulating paper 9 (as shown in fig. 3), and in the twisting process, the root of each U-shaped line part is not in contact with the step surface of the notch of the stator core slot, and the stress part is transferred to the upper part of the insulating paper, thereby effectively avoiding the damage of the insulating paper and the damage of a paint film of an enameled wire.
Although embodiments of the present invention have been described, various changes or modifications may be made by one of ordinary skill in the art within the scope of the appended claims.
