Abstract
Description
Technical Field
[0001] The utility model relates to the field of motor production equipment, in particular to a surplus wire clamping mechanism used on an automatic winding machine for a motor stator. Background Art
[0002] After the winding machine completes winding the motor stator coil, the enameled wire needs to be cut off at the end. If the wire is directly cut off at the end by an instrument, the wire will be deformed and thinned due to the tension. Not only will the exact location of the cut be uncertain, but it will also affect the uniformity and stability of the entire current, thereby affecting the product quality and operating performance of the motor. If the enameled wire is cut off manually, the efficiency is obviously low, and the consistency of the reserved wire length cannot be guaranteed.
[0003] In view of this, the inventors conducted in-depth research on the above-mentioned defects in the prior art, and thus came up with this case. Utility Model Content

A bearing 11 is provided on the rotating shaft 10, and the bearing 11 is embedded in the support plate 12. The bottom of the support plate 12 is fixed on the left and right connecting plates 3; the remaining line clamp 9 is fixed above the rotating square rod 5; a fixed plate 7 is erected on the rear side of the rotating square rod 5, and the bottom of the fixed plate 7 is fixed to the rear side of the base plate 1, and the parallel cylinder 8 is fixed on the fixed plate 7, and the driving end of the parallel cylinder 8 is arranged toward the lower side of the remaining line clamp 9, and can drive the remaining line clamp 9 to clamp and cut the wire end after the motor stator is wound.
[0025] Among them, the residual wire clamp 9 includes a base 91, a spiral return spring 92, a magnet 93, a clamp movable rod 94, a clamp fixed rod 95 and a wire arrangement sleeve 96. A notch is provided on one side of the lower part of the base 91, and a circular hole is opened in the notch upward through the top surface of the base 91. The clamp movable rod 94 and the clamp fixed rod 95 are relatively inserted in the circular hole, and a clamping gap is formed between the upper parts of the clamp movable rod 94 and the clamp fixed rod 95; the lower part of the clamp movable rod 94 contacts one end of the spiral return spring 92 in the notch, and the base 91 is provided with a parallel cylinder 8 next to the notch, and the driving end of the parallel cylinder 8 is facing the lower side of the clamp movable rod 94 in the notch, the wire arrangement sleeve 96 is sleeved on the clamp movable rod 94 and the clamp fixed rod 95, and a magnet 97 is also embedded on the base 91 below the wire arrangement sleeve 96.
[0026] At the same time, an annular fixing groove 961 is provided in the middle of the wire sleeve 96, and a semicircular notch 71 is provided on the top of the fixed plate 7 near the wire sleeve 96, and the outer diameter of the wire sleeve 96 at the fixing groove 961 is adapted to the inner diameter width of the semicircular notch 71, and the wire sleeve 96 can be stuck in the semicircular notch 71 on the top of the fixed plate 7 at the annular fixing groove 961.
[0027] In order to facilitate the collection of waste thread ends, a waste thread slide 13 is further provided on the rear side of the fixed plate 7 , and the waste thread slide 13 is located below the rear side of the semicircular notch 71 .
[0028] The pneumatic slide 2, bottom cylinder 4, parallel cylinder 8, remaining wire clamp 9 and waste wire slide 13 are all two and are symmetrically arranged above the bottom plate 1. This makes it possible to more efficiently cut and remove the waste wire generated after the motor stator is wound.
[0029] The working principle of the residual wire clamp mechanism used in the motor stator automatic winding machine is as follows: Figure 6 As shown, when the motor stator automatic winding machine is winding the motor stator 14, the winding thread end 15 will first be placed in the clamping gap between the clamping claw movable rod 94 and the clamping claw fixed rod 95 of the residual wire clamping mechanism 9 to clamp it, and then the wire nozzle of the winding machine will pull the rear section of the thread end 15 to wind the motor stator. When the winding is completed, the thread end 15 needs to be clamped off and removed. At this time, the clamping claw movable rod 94 of the residual wire clamping claw 9 is driven by the driving end of the parallel cylinder 8 to move, so that it is closed with the clamping claw fixed rod 95 at the clamping gap to clamp off the waste thread end 15 after the motor stator 14 is wound. Then the parallel cylinder 8 retracts the spiral return spring 92 to reset the clamping claw movable rod 94, and the clamping claw movable rod 94 and the clamping claw fixed rod 95 of the residual wire clamping claw 9 will release the thread end after clamping off, and then the swing cylinder 6 drives the rotating square rod 5 to rotate and flips the entire residual wire clamping claw 9. The wire arranging sleeve 96 on is stuck in the semicircular notch 71 at the top of the fixed plate 7, and then the bottom cylinder 4 drives the left and right connecting plates 3 and brings the clamping movable rod 94 and the clamping fixed rod 95 of the overturned residual wire clamping jaw 9 to move back and forth. At this time, the wire arranging sleeve 96 of the residual wire clamping jaw 9 is stuck in the semicircular notch 71 at the top of the fixed plate 7 and cannot move. The clamping movable rod 94 and the clamping fixed rod 95 of the residual wire clamping jaw 9 will be pulled back and forth in the wire arranging sleeve 96, which makes the wire arranging sleeve 96 sleeved on the clamping movable rod 94 and the clamping fixed rod 95 push the waste wire head between the clamping movable rod 94 and the clamping fixed rod 95 outward until the waste wire head is separated from the clamping opening between the clamping movable rod 94 and the clamping fixed rod 95 of the residual wire clamping jaw 9 and falls into the waste wire slide 13 for collection, thus completing the processing of the residual wire head of the motor stator after winding.
[0030] In this example, the utility model is designed to include a pneumatic slide 2, left and right connecting plates 3, a bottom cylinder 4, a rotating square rod 5, a swing cylinder 6, a fixed plate 7, a parallel cylinder 8 and a residual wire clamp 9. The parallel cylinder 8 drives the residual wire clamp 9 to clamp the waste wire end after the motor stator is wound at the clamping mouth, and then the parallel cylinder 8 retracts to loosen the wire end at the residual wire clamp 9. Then the swing cylinder 6 drives the rotating square rod 5 to rotate and flip the residual wire clamp 9, so that the wire sleeve 96 on the residual wire clamp 9 is stuck on the top of the fixed plate 7. The semicircular notch 71 at the bottom is then driven by the air cylinder 4 at the bottom to drive the left and right connecting plates 3 to move the movable clamping rod 94 and the fixed clamping rod 95 of the flipped residual wire clamping jaw 9 back and forth. The movable clamping rod 94 and the fixed clamping rod 95 of the residual wire clamping jaw 9 will be pulled back and forth in the wire arranging sleeve 96, which causes the wire arranging sleeve 96 sleeved on the movable clamping rod 94 and the fixed clamping rod 95 to push the waste wire between the ends of the movable clamping rod 94 and the fixed clamping rod 95 outward, and make the waste wire fall off the residual wire clamping jaw 9. In this way, the wire can be cut off and removed without being deformed or thinned. The specific cutting position is accurate, which can ensure the consistency of the length of the reserved wire and will not affect the uniformity and stability of the current when the motor stator is running in the future, thereby ensuring the product quality and operating effect of the motor. Thus, the purpose of novel design, reasonable structure and good application effect is achieved.

It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, which all fall within the scope of protection of the present invention.
