Description

Technical Field

[0001] The invention belongs to the technical field of flat wire motor winding bending, in particular to an auxiliary tool for flat wire motor stator winding bending processing. Background Art

[0002] Flat wire motor windings refer to motor windings that are wound with flat-shaped wires in the motor. Compared with traditional round wires, flat wire motor windings generally have higher winding density and fill factor because flat wires can fill stator slots more efficiently and can accommodate more wires in the same space.

[0003] Since flat wire windings can accommodate more wires in a limited space, higher power density can be achieved, that is, greater power output is provided at the same size. The flat wire windings have a higher filling factor, resulting in lower resistance and inductance in the windings, thereby reducing energy loss when current passes through. Since the flat wire windings have a larger surface area, heat can be dissipated more effectively, allowing the motor to maintain a lower temperature when running at high loads.

[0004] In the existing bending process of the flat wire winding, the inner and outer ring flat wires need to be bent. Since the flat wire spacing is too small, interference is easily caused during the bending process, resulting in defective products. Summary of the invention

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] like Figures 1 to 12 As shown, the present invention provides an auxiliary tooling for bending processing of stator windings of flat wire motors, wherein a flat wire winding 2 distributed in an array is installed in a flat wire stator 1, an outer ring slide groove 3 is installed on the upper side of the flat wire stator 1, an inner ring slide groove 31 is installed on the upper side of the flat wire stator 1, a deflection mechanism is slidably connected on the upper side of the flat wire winding 2, and an array-distributed clamping mechanism is installed on the upper side of the flat wire stator 1;

[0039] Among them, an outer ring sliding block 58 is fixedly connected to the outer contour of the first deflection ring 5, the first deflection ring 5 is rotatably connected to the outer ring sliding groove 3, a sliding groove for the outer ring sliding block 58 to deflect and slide is provided on the inner contour of the outer ring sliding groove 3, an inner ring sliding rod 59 is fixedly connected to the inner contour of the fourth deflection ring 56, the fourth deflection ring 56 is rotatably connected to the inner ring sliding groove 31, and a sliding groove for the inner ring sliding rod 59 to deflect and slide is provided on the inner ring sliding groove 31;

[0040] When the first deflection ring 5 slides downward, the outer ring sliding block 58 and the outer ring sliding groove 3 cause the first deflection ring 5 to slide downward and deflect at the same time. When the fourth deflection ring 56 slides downward, the inner ring sliding rod 59 and the inner ring sliding groove 31 cause the fourth deflection ring 56 to slide downward and deflect at the same time.

[0041] The deflection mechanism includes a first deflection shaft 51 fixedly connected to the first deflection ring 5, the second deflection ring 52 fixedly connected to the second deflection shaft 53, the third deflection ring 54 fixedly connected to the third deflection shaft 55, the fourth deflection ring 56 fixedly connected to the fourth deflection shaft 57, the first deflection shaft 51 is slidably connected to the outer contour of the first deflection shaft 51, the upper side of the first steering column 4 is fixedly connected to the extrusion shaft 4, the extrusion shaft 4 is fixedly connected to the second steering column 42 sliding on the outer contour of the second deflection shaft 53, the extrusion shaft 4 is fixedly connected to the third steering column 43 sliding on the outer contour of the third deflection shaft 55, and the extrusion shaft 4 is fixedly connected to the fourth steering column 44 sliding on the outer contour of the fourth deflection shaft 57.

[0042] The second deflection shaft 53 is provided with an arc groove for the fourth steering column 44 and the third steering column 43 to pass through, the first deflection shaft 51 is provided with an arc groove for the fourth steering column 44, the third steering column 43 and the second steering column 42 to pass through, the outer contours of the first deflection shaft 51 and the third deflection shaft 55 are provided with an arc groove for cooperating with the first steering column 41 and the third steering column 43 to make the first deflection ring 5 and the third deflection ring 54 deflect in the same direction, the outer contours of the second deflection shaft 53 and the fourth deflection shaft 57 are provided with an arc groove for cooperating with the second steering column 42 and the fourth steering column 44 to make the second deflection ring 52 and the fourth deflection ring 56 deflect in the same direction, and the deflection direction of the second deflection ring 52 and the fourth deflection ring 56 is opposite to the deflection direction of the first deflection ring 5 and the third deflection ring 54.

[0043] The above scheme is adopted: by starting the extrusion shaft 4 to move downward, the first steering column 41, the second steering column 42, the third steering column 43 and the fourth steering column 44 are driven to move downward synchronously, and then the first deflection ring 5, the second deflection ring 52, the third deflection ring 54 and the fourth deflection ring 56 are driven to move downward synchronously. Taking the first deflection ring 5 as an example, when the slide groove on the lower side of the first deflection ring 5 contacts the upper side of the flat wire winding 2, the extrusion shaft 4 drives the first steering column 41 to continue to move downward, and then the first steering column 41 drives the first deflection ring 5 to deflect clockwise through the arc-shaped slide groove of the first deflection shaft 51. Similarly, the third steering column 43 drives the third deflection ring 54 to deflect clockwise, and the second steering column 42 and the fourth steering column 44 drive the second deflection ring 52 and the fourth deflection ring 56 to deflect counterclockwise, thereby driving The flat wire winding 2 deflects clockwise or counterclockwise around the axis of the first deflection ring 5, and the slide grooves provided on the outer ring slide groove 3 and the inner ring slide groove 31 limit the height of the downward sliding deflection of the first deflection ring 5 and the fourth deflection ring 56, so that the first deflection ring 5 can move downward while deflecting. Similarly, the second deflection ring 52, the third deflection ring 54 and the fourth deflection ring 56 slide downward while deflecting. Due to the rotational connection between the first deflection ring 5, the second deflection ring 52, the third deflection ring 54 and the fourth deflection ring 56, the first deflection ring 5, the second deflection ring 52, the third deflection ring 54 and the fourth deflection ring 56 are always at the same height. When the first deflection ring 5, the second deflection ring 52, the third deflection ring 54 and the fourth deflection ring 56 move to the limit position, the processing of the flat wire winding 2 is completed.

[0044] like Figures 10 to 12 As shown, the clamping mechanism includes a mounting frame 7 mounted on the upper side of the flat wire stator 1, a sliding detection rod 71 is slidably connected in a symmetrical array inside the mounting frame 7, a steering block 72 is rotatably connected to the upper side of the sliding detection rod 71, the steering block 72 is rotatably connected to a fixed bracket 73, the fixed bracket 73 is fixedly connected to the inner wall of the mounting frame 7, the steering block 72 is rotatably connected to the side away from the fixed bracket 73, the sliding extrusion block 74 is slidably connected to the inner wall of the mounting frame 7, the sliding extrusion block 74 is wedge-shaped and slidably connected to a transmission ring 75, and the transmission ring 75 is fixedly connected to a fixed suction cup 76.

[0045] A sliding groove is provided in the sliding detection rod 71 , a wedge block is fixedly connected in the sliding detection rod 71 , a sliding piston 77 is slidably connected in the fixed suction cup 76 , and the wedge block and the sliding piston 77 are wedge-matched.

[0046] The fixed suction cup 76 is fixedly connected to a clamping block 712, a sliding column 711 is fixedly connected to the lower side of the clamping block 712, the sliding column 711 is slidably connected to the fixed column 710, the fixed column 710 is fixedly connected to the sliding fixed block 79, a limiting tension spring 713 is arranged between the clamping block 712 and the sliding fixed block 79, the sliding fixed block 79 is slidably connected to the mounting frame 7, and a shaping mechanism is fixedly connected to the upper side of the mounting frame 7 in a staggered and symmetrical manner.

[0047] The above scheme is adopted: the operator installs the mounting frame 7 on the upper side of the flat wire stator 1. When the mounting frame 7 moves downward, the sliding detection rod 71 first contacts the flat wire stator 1, and the sliding detection rod 71 is squeezed by the flat wire stator 1 and slides upward. Since the fixed bracket 73 is fixed to the inner wall of the mounting frame 7, the steering block 72 is squeezed by the sliding detection rod 71 and rotates counterclockwise around the cylindrical axis of the fixed bracket 73, thereby driving the sliding extrusion block 74 to slide downward, and then driving the transmission ring 75 and the fixed suction cup 76 to slide leftward, toward the direction of the flat wire winding 2. The air inside the fixed suction cup 76 is squeezed out to fix the fixed suction cup 76 to the flat wire winding 2. At the same time, the sliding detection rod 71 drives the wedge block to slide upward, and the wedge-shaped cooperation between the wedge block and the sliding piston 77 causes the sliding piston 77 to slide horizontally in the direction of the sliding detection rod 71, so that the air density in the fixed suction cup 76 is further reduced, and the fixation of the fixed suction cup 76 to the flat wire winding 2 is strengthened, so as to ensure that the flat wire winding 2 itself will not slide up and down during the bending process, and will not affect the bending process.

[0048] When the flat wire winding 2 is clamped, if the mounting frame 7 has not yet completely contacted the flat wire stator 1, the fixed suction cup 76 first clamps and fixes the flat wire winding 2. As the mounting frame 7 is completely in contact with the flat wire stator 1, the fixed suction cup 76 is driven by the flat wire winding 2 to move upward, thereby driving the clamping block 712 and the sliding column 711 to move upward, thereby stretching the limiting tension spring 713. At the same time, since the fixed suction cup 76 moves in the direction of the flat wire winding 2, the sliding fixing block 79 is also driven to slide in the direction of the flat wire winding 2, and since the sliding fixing block 79 is limited and slides on the mounting frame 7, the fixed suction cup 76 will not separate from the mounting frame 7. When the clamping is completed, the sliding detection rod 71 slides downward due to its own weight, and then the sliding extrusion block 74 slides upward, and the sliding piston 77 slides in the direction of the flat wire winding 2. The limiting tension spring 713 contracts, driving the sliding column 711 and the clamping block 712 to slide downward, thereby driving the fixed suction cup 76 to slide downward.

[0049] like Figure 7 and Figure 8As shown, the shaping mechanism is staggered and symmetrically arranged on the lower sides of the first deflection ring 5, the second deflection ring 52, the third deflection ring 54 and the fourth deflection ring 56. The shaping mechanism is staggered and symmetrically arranged up and down. Taking the shaping mechanism on the lower side of the first deflection ring 5 as an example, the shaping mechanism includes a fixed block 6 fixedly connected to the lower side of the first deflection ring 5, the fixed block 6 is slidably connected to a limiting sliding column 64, the limiting sliding column 64 is fixedly connected to a sliding bracket 61, a first return spring 62 is arranged between the sliding bracket 61 and the fixed block 6 around the limiting sliding column 64, and the sliding bracket 61 is rotatably connected to a limiting rod 63.

[0050] The above scheme is adopted: during the bending process, the position where the bottom of the flat wire winding 2 on the flat wire stator 1 is clamped by the clamping mechanism and the top bending position of the flat wire winding 2 are both provided with a shaping mechanism. When the flat wire winding 2 is bent, the flat wire winding 2 squeezes the limiting rod 63 to slide horizontally in the direction of the fixed block 6, and the limiting rod 63 rotates, and the bending part of the flat wire winding 2 is squeezed and buffered by the first return spring 62, so as to ensure that the bending part of the flat wire winding 2 is excessively smooth and enhance the service life of the processed flat wire winding 2.

[0051] like Fig.11 and Fig.12 As shown, the fixed suction cup 76 is composed of a suction cup and a ring, wherein the suction cup is made of a flexible material.

[0052] The curvature of the arc-shaped position of the clamping block 712 is consistent with the curvature of the outer contour of the circular ring of the fixed suction cup 76 .

[0053] The sliding fixed block 79 penetrates and is slidably connected with a limiting slide rod 714 . One end of the limiting slide rod 714 away from the sliding fixed block 79 is fixedly connected to the mounting bracket 7 . A second return spring 715 is wound around the limiting slide rod 714 .

[0054] The above scheme is adopted: when the fixed suction cup 76 drives the sliding fixed block 79 to slide in the direction of the flat wire winding 2, the second return spring 715 is squeezed. When the clamping mechanism completes clamping, the second return spring 715 rebounds, driving the sliding fixed block 79 to slide horizontally in the direction away from the flat wire winding 2, thereby driving the fixed suction cup 76 to reset.

[0055] The working principle and use process of the present invention:

[0056] By starting the extrusion shaft 4 to move downward, the first steering column 41, the second steering column 42, the third steering column 43 and the fourth steering column 44 are driven to move downward synchronously, and then the first deflection ring 5, the second deflection ring 52, the third deflection ring 54 and the fourth deflection ring 56 are driven to move downward synchronously. Taking the first deflection ring 5 as an example, when the slide groove on the lower side of the first deflection ring 5 contacts the upper side of the flat wire winding 2, the first steering column 41 is driven by the extrusion shaft 4 to continue to move downward, and then the first steering column 41 drives the first deflection ring 5 to deflect clockwise through the arc-shaped slide groove of the first deflection shaft 51. Similarly, the third steering column 43 drives the third deflection ring 54 to deflect clockwise, and the second steering column 42 and the fourth steering column 44 drive the second deflection ring 52 and the fourth deflection ring 56 to deflect counterclockwise, thereby driving the flat wire winding 2. The group 2 deflects clockwise or counterclockwise around the axis of the first deflection ring 5, and the slide grooves arranged on the outer ring slide groove 3 and the inner ring slide groove 31 limit the height of the first deflection ring 5 and the fourth deflection ring 56 sliding down and deflecting, so that the first deflection ring 5 can move downward while deflecting. Similarly, the second deflection ring 52, the third deflection ring 54 and the fourth deflection ring 56 slide downward while deflecting. Due to the rotational connection between the first deflection ring 5, the second deflection ring 52, the third deflection ring 54 and the fourth deflection ring 56, the first deflection ring 5, the second deflection ring 52, the third deflection ring 54 and the fourth deflection ring 56 are always at the same height. When the first deflection ring 5, the second deflection ring 52, the third deflection ring 54 and the fourth deflection ring 56 move to the limit position, the processing of the flat wire winding 2 is completed.

[0057] The operator installs the mounting frame 7 on the upper side of the flat wire stator 1. When the mounting frame 7 moves downward, the sliding detection rod 71 first contacts the flat wire stator 1, and the sliding detection rod 71 slides upward due to the extrusion of the flat wire stator 1. Since the fixed bracket 73 is fixed to the inner wall of the mounting frame 7, the steering block 72 is squeezed by the sliding detection rod 71 and rotates counterclockwise around the cylindrical axis of the fixed bracket 73, thereby driving the sliding extrusion block 74 to slide downward, and then driving the transmission ring 75 and the fixed suction cup 76 to slide to the left, and squeeze in the direction of the flat wire winding 2. The air inside the fixed suction cup 76 is squeezed out to fix the fixed suction cup 76 to the flat wire winding 2. At the same time, the sliding detection rod 71 drives the wedge block to slide upward, and the wedge-shaped cooperation between the wedge block and the sliding piston 77 causes the sliding piston 77 to slide horizontally in the direction of the sliding detection rod 71, so that the air density in the fixed suction cup 76 is further reduced, and the fixation of the fixed suction cup 76 to the flat wire winding 2 is strengthened, so as to ensure that the flat wire winding 2 itself will not slide up and down during the bending process, and will not affect the bending process.

[0058] When the flat wire winding 2 is clamped, if the mounting frame 7 has not yet completely contacted the flat wire stator 1, the fixed suction cup 76 first clamps and fixes the flat wire winding 2. As the mounting frame 7 is completely in contact with the flat wire stator 1, the fixed suction cup 76 is driven by the flat wire winding 2 to move upward, thereby driving the clamping block 712 and the sliding column 711 to move upward, thereby stretching the limiting tension spring 713. At the same time, since the fixed suction cup 76 moves in the direction of the flat wire winding 2, the sliding fixing block 79 is also driven to slide in the direction of the flat wire winding 2, and since the sliding fixing block 79 is limited and slides on the mounting frame 7, the fixed suction cup 76 will not separate from the mounting frame 7. When the clamping is completed, the sliding detection rod 71 slides downward due to its own weight, and then the sliding extrusion block 74 slides upward, and the sliding piston 77 slides in the direction of the flat wire winding 2. The limiting tension spring 713 contracts, driving the sliding column 711 and the clamping block 712 to slide downward, thereby driving the fixed suction cup 76 to slide downward.

[0059] During the bending process, shaping mechanisms are provided at the bottom of the flat wire winding 2 on the flat wire stator 1 where it is clamped by the clamping mechanism and at the top bent portion of the flat wire winding 2. When the flat wire winding 2 is bent, the flat wire winding 2 squeezes the limiting rod 63 to slide horizontally toward the fixed block 6, and the limiting rod 63 rotates. The first return spring 62 squeezes and buffers the bent portion of the flat wire winding 2 to ensure that the bent portion of the flat wire winding 2 is excessively smooth, thereby enhancing the service life of the processed flat wire winding 2.

[0060] When the fixed suction cup 76 drives the sliding fixed block 79 to slide in the direction of the flat wire winding 2, the second return spring 715 is squeezed. When the clamping mechanism completes clamping, the second return spring 715 rebounds, driving the sliding fixed block 79 to slide horizontally in the direction away from the flat wire winding 2, thereby driving the fixed suction cup 76 to reset.
