In fig. 2, the guide chuck 4 is mounted on a fourth slider 9, and the fourth slider 9 is vertically slidably matched with a guide pillar on the bracket 1, so that the vertical sliding mounting of the guide chuck 4 on the bracket 1 is realized. The alignment collet 4 is provided with a vertical alignment groove 41. The first sliding block 2 is vertically arranged on the bracket 1 in a sliding manner through a guide post 11 on the bracket 1. The second slider 3 is in sliding fit with the first slider 2 along the vertical line 21 of the clamping surface 20 clamped by the guide clamp 4, and the pull rod 7 is connected with the second slider 3, i.e. the pull rod 7 is in sliding fit with the first slider 2 through the second slider 3 along the vertical line 21 of the clamping surface 20 clamped by the guide clamp 4. The pull rod 7 is provided with a pin 71 which is in the same direction as the vertical line of the clamping surface clamped by the guide clamp 4. The first power device 13 is connected with the first sliding block 2 to push the first sliding block 2 to vertically slide on the bracket 1; the second power device 15 is connected with the second sliding block 3 to push the second sliding block 3 to slide on the first sliding block 2 along the vertical direction of the clamping surface clamped by the guide clamping head 4; the third power device 16 is connected with the guide chuck 4 to push the guide chuck 4 to slide vertically on the bracket 1.
The first power device 13, the second power device 15, the third power device 16, and the clamping device 14 may be an air cylinder, a hydraulic cylinder, a screw sliding table, or the like. In fig. 2, the cylinders are shown.
The invention pushes the guide chuck 4 to slide downwards through the third power device 16, and the guide chuck 4 clamps and guides the wiring lug 30 through the guide groove 41, so that the mounting hole of the wiring lug and the threaded hole of the motor shell are positioned on the same vertical line; then the second slider 3 is pushed by the second power device 15 to slide along the vertical line 21 direction of the clamping surface 20 clamped by the guide clamping head 4, the pin 71 is inserted into the mounting hole of the wiring piece 30, and the pull rod 7 hooks the wiring piece; finally, the third power device 16 pushes the first sliding block 2 to move vertically, so that the pull rod 7 pulls the wiring lug 30 to a designated position, and finally, the mounting hole of the wiring lug is aligned with the threaded hole of the motor shell. The lug reshaping is carried out through the reshaping mechanism, the reshaping quality and consistency requirements of the lug can be guaranteed, the lug is easy to be completely attached to the motor during installation, the lug is convenient to install, and the reshaping mode is higher than manual reshaping efficiency, so that the motor assembly efficiency can be improved.
As shown in fig. 6, in order to facilitate the alignment of the wire connector lug, the distance from the bottom of the upper end of the alignment groove 41 to the center of the clamping opening of the alignment chuck 4 is smaller than the distance from the bottom of the lower end of the alignment groove 41 to the center of the clamping opening of the alignment chuck 4, and the opening of the notch at the lower end of the alignment groove 41 is larger than the opening of the notch at the upper end of the alignment groove 41 (see fig. 7).
As shown in fig. 6, since the tab is connected to the copper wire winding of the motor stator, the copper wire 31 at the lower end of the tab 30 is bent when the stator winding is wound, in order to ensure that the tie rod 7 straightens the copper wire 31 at the lower end of the tab, as shown in fig. 2, 3 and 6, the shaping rod 8 is fixedly connected with the second sliding block 3, the shaping rod 8 is provided with a shaping groove 81 which is vertically arranged, and the pull rod 7 is arranged in the shaping groove 81; the second slider 3 is provided with a vertical hole in clearance fit with the pull rod 7, the pull rod 7 passes through the vertical hole in clearance fit with the second slider 3 and then extends to the third slider 5, and is connected with the third slider 5 in a sliding fit manner in the vertical direction along the clamping surface clamped by the guide clamping head, and the fourth power device 12 is connected with the third slider 5 to push the third slider 5 to slide vertically on the bracket 1. In this way, the pull rod 7 can be pulled by the third sliding block 5 to move vertically along the shaping groove of the shaping rod 8, and can also be controlled by the second sliding block 3 to slide in the vertical direction along the clamping surface clamped by the guide clamping head. Therefore, the third sliding block 5 can be pulled by the fourth power device 12, so that the pull rod 7 pulls the wiring piece to slide along the shaping groove 81, and the shaping groove 81 can straighten the copper wire 31 at the lower part of the wiring piece in the process of stretching the wiring piece by the pull rod 7.
Since the generator stator winding is provided with four tabs (U, V, W and ground), the mechanism requires four shaping units in order to shape the tabs of one stator winding at a time. Since the four lugs of the stator winding are distributed around the circumference of the stator, i.e. the direction of movement of the tie rods 7 of each shaping unit to hook the lugs is along the radial direction of the stator winding. Because the motion directions of the pull rods are different, the control is inconvenient. As shown in fig. 2 and 8, the mechanism is further provided with a turntable 6, the turntable 6 is rotatably mounted on the first slider 2, the turntable 6 is provided with a wire groove 61, a guide block 62 adapted to the wire groove 61 is arranged in the wire groove 61, the guide block 62 is fixedly connected with the second slider 3, and the second power device 15 is connected with the turntable 6 to push the turntable 6 to rotate. The second power device 15 pushes the turntable 6 to rotate, so that the guide block 62 in the wire groove 61 slides along the wire groove 61, and thus the second slider 3 is driven to slide on the first slider 2 along the vertical direction of the clamping surface clamped by the guide chuck 4, and the pull rod 7 is pulled to slide along the vertical direction of the clamping surface clamped by the guide chuck 4 in the sliding process of the second slider 3, namely, the second power device 15 of the device is connected with the second slider 3 through the turntable 6 to push the second slider 3 to slide on the first slider 2 along the vertical direction of the clamping surface clamped by the guide chuck 4. By means of the mode, three wire grooves 61 can be formed in the rotary table 6, and 4 pull rods can move towards the radial direction of the stator at the same time, so that the wiring lugs of one stator winding can be shaped at a time, and production efficiency can be improved.
In order to control the stroke of the first slider 2, a limiting block 17 limiting the stroke of the first slider 2 and a limiting block 18 limiting the stroke of the third slider 5 are arranged on the bracket 1, and in fig. 2, the limiting block 17 and the limiting block 18 are arranged on the guide post 11 of the bracket 1. The strokes of the shaping rod 8 and the pull rod 7 can be controlled through the limiting block 17 and the limiting block 18 respectively, so that the clamping head and the stator winding can be prevented from being damaged due to overlarge descending stroke.
In the device shaping process, as shown in fig. 2, the third power device 16 pushes the guide chuck 4 to move downwards, and the guide chuck 4 clamps and guides the wiring lug 30 through the guide groove 41, so that the wiring lug is clamped and guided, and the mounting hole of the wiring lug and the threaded hole of the motor shell are positioned on the same vertical line; after the guide, the first power device 13 pushes the first sliding block 2 to move downwards, and the limiting block 16 limits the travel of the first sliding block 2, so that the shaping rod 8 moves above the guide chuck 4; then, the fourth power device 12 pushes the third sliding block 5 to move downwards, so that the pin 71 of the pull rod 7 is aligned with the mounting hole of the wiring lug; then, the second power device 15 pushes the turntable 6 to rotate, the turntable 6 pulls the second sliding block 3 to slide, the pull rod 7 and the shaping rod 8 slide on the first sliding block 2 along the vertical direction of the clamping surface clamped by the guide clamping head 4, and the pin 71 of the pull rod 7 is inserted into the mounting hole of the wiring piece; and then the third sliding block 5 is pulled to move upwards through the fourth power device 12, so that the wiring lug is pulled to a specified height, the mounting hole of the wiring lug is aligned with the threaded hole of the motor shell, and in the process that the wiring lug is pulled by the pull rod 7, the straight line of the lower end of the wiring lug is ensured to be vertical through the shaping groove 81 of the shaping rod 8.
