Detailed Description
The technical scheme of the invention is further described below by the specific embodiments with reference to the accompanying drawings.
As shown in fig. 1 to 9, a flat copper wire twisting device for an armature winding includes a frame 10, a holding assembly 20 disposed above the frame 10 for holding the armature winding, a driving device connected to the holding assembly 20 for driving the holding assembly 20 holding the armature winding to move up and down, a truncated cone-shaped base 30 located right below the holding assembly 20 and connected to the frame 10, two or more hollow cylindrical drums 40 coaxially arranged inside and outside, and a driving mechanism 50.
Wherein, the bottom end of each rotary drum 40 is opened, the top surface of each rotary drum 40 is coaxially provided with a through hole 44, the edge of each through hole 44 is outwards extended to form a boss 45, and the boss 45 of each rotary drum 40 is coaxially sleeved inside and outside; the top surface of the base 30 is coaxially provided with a plurality of annular grooves 31, and the bottom ends of the rotary drums 40 are respectively coaxially clamped into the corresponding annular grooves 31 to be connected with the base 30 and can rotate relative to the base 30 around the central axis of the rotary drums; the top end of each boss 45 corresponds to each layer of flat copper wire of the armature assembly up and down, and the top surface of each boss 45 is provided with a plurality of jacks 41 for inserting the ends of the corresponding layers of flat copper wires along the circumferential direction; the driving mechanism 50 is connected to the frame 10 and is capable of driving the drums 40 to rotate together, and the rotation directions of the two adjacent drums 40 are opposite. According to the flat copper wire twisting device, the ends of each layer of flat copper wire of the armature winding are respectively inserted into the corresponding insertion holes 41, the driving mechanism 50 drives the rotating drums 40 to jointly rotate, and the rotating directions of the two adjacent rotating drums 40 are opposite, so that the ends of the two adjacent layers of flat copper wires of each layer of the armature winding are twisted in opposite directions. The flat copper wire twisting device is suitable for twisting treatment of flat copper wires of two-layer armature windings and multi-layer armature windings, and is simple in structure, convenient to operate and low in manufacturing cost.
Specifically, the clamping assembly 20 includes: the armature winding comprises a hollow sleeve 21, a supporting plate 22 coaxially sleeved on the outer side of the sleeve 21 and used for supporting the sleeve 21 and the armature winding, a plurality of supporting rods 23 inserted into the flat copper wire at intervals along the circumferential direction of the armature winding, and a fixing plate 24 connected with the supporting plate 22 and used for clamping and fixing the supporting rods 23. Wherein, the top of the armature winding is arranged in the sleeve 21, and the locking connection with the sleeve 21 is realized through pin positioning and screws. The two ends of the supporting plate 22 are connected with the frame 10 through two guide posts 14 arranged at two sides of the base 30, so as to avoid the deviation of the armature winding in the process of moving up and down, and further to influence the insertion or extraction of the end of the flat copper wire into the jack 41. The ends of the layers of flat copper wire of the armature winding extend beyond the support plate 22. In order to prevent the armature winding from loosening in the twisting process, a plurality of clamping grooves 221 can be formed in the bottom surface of the support plate 22 along the circumferential direction, each support rod 23 is respectively clamped in each corresponding clamping groove 221, the end part of each support rod 23 extends out of the corresponding clamping groove 221 and is inserted into a flat copper wire, and then the support rod 23 is connected with the support plate 22 through the fixing plate 24, so that each support rod 23 is clamped and fixed in the corresponding clamping groove 221, and the connection stability of the armature winding is further improved.
In the present invention, the driving means for driving the holding unit 20 and the armature winding to move up and down together is a hydraulic cylinder or a cylinder such as a cylinder.
In this flat copper wire twisting device, the driving mechanism 50 includes: the rotary drum 40 comprises a central shaft 51 coaxially arranged in the rotary drum 40 and connected to the base 30, two driving rods 52 for pushing the rotary drums 40 to rotate together, two first connecting rods 53 respectively connected to one ends of the two driving rods 52, two second connecting rods 54 respectively connected to the other ends of the two driving rods 52, a first sliding block 56 rotatably connected with one ends of the two first connecting rods 53, which are far away from the driving rods 52, through a first rotating shaft 55, a second sliding block 58 rotatably connected with one ends of the two second connecting rods 54, which are far away from the driving rods 52, through a second rotating shaft 57, and an air cylinder 59. Wherein, two driving rods 52 are crossed and respectively pass through each rotary drum 40 and are coaxially and rotatably connected with the central shaft 51. The central axis of the central shaft 51, the central axis of the first rotating shaft 55 and the central axis of the second rotating shaft 57 are on the same plane; the first slide block 56 and the second slide block 58 are both in sliding connection with the frame 10; the fixed end of the air cylinder 59 is connected with the frame 10, and the movable end is connected with the first slider 56 or the second slider 58 and is used for pushing the first slider 56 or the second slider 58 to slide towards or away from the base 30. The cylinder 59 pushes the first sliding block 56 or the second sliding block 58 to slide, so that the two driving rods 52 are driven to reversely rotate around the central shaft 51, and the rotating cylinders 40 of all layers are pushed to rotate relative to the base 30, and the structure is relatively simple.
Further, in order to realize simultaneous reverse rotation of two adjacent drums 40 in each drum 40, a first through groove 42 and a second through groove 43 are radially formed on the side of each drum 40; wherein, the width of each first through groove 42 is consistent with the width of the driving rod 52; the width of each second through groove 43 is larger than the width of the driving rod 52, and the radian of each second through groove 43 is equal; the first through grooves 42 of each rotary drum 40 which are arranged at intervals are correspondingly arranged and are communicated through the second through grooves 43 of the rotary drum 40 which are positioned in the middle; the second through grooves 43 of the rotary drums 40 which are arranged at intervals are correspondingly arranged and are communicated through the first through grooves 42 of the rotary drums 40 which are positioned in the middle; the first through groove 42 and the second through groove 43 of each drum 40 cooperate with each other to form two through grooves, and the two driving rods 52 are respectively disposed in the two through grooves. Thus, when the two driving levers 52 are rotated in opposite directions, each of the drums 40 is pushed to be rotated simultaneously, and the rotation directions of the adjacent two drums 40 are opposite.
In order to ensure the smooth sliding of the first sliding block 56 and the second sliding block 58, a first sliding rail 11 and a second sliding rail 12 are respectively arranged on the frame 10 along the direction parallel to the plane, the first sliding block 56 is in sliding connection with the first sliding rail 11, and the second sliding block 58 is in sliding connection with the second sliding rail 12; in addition, the frame 10 is further provided with a corresponding guide rod 13 for guiding the first slider 56 and the second slider 58 to slide respectively.
Since the end of the flat copper wire is frequently inserted into and pulled out of the insertion hole 41 for a long period of time, there is a high possibility that the insertion hole 41 of each drum 40 is severely worn. To further improve the problem, a circular bracket 61 and a plurality of wolf's teeth bars 62 may be added, wherein the bracket 61 is coaxially clamped on the top surface of the drum 40 located at the outermost layer, and a plurality of clamping grooves 611 are circumferentially arranged on the top surface of the bracket 61 at intervals; each of the wolf's teeth bars 62 is respectively engaged into each of the engaging grooves 611, and two adjacent wolf's teeth bars 62 are mutually spliced to form a plurality of insertion holes 621, and each insertion hole 621 corresponds to each insertion hole 41 arranged in the radial direction up and down. When the flat copper wire ends of the armature windings are inserted, the ends of the flat copper wires need to pass through the corresponding sockets 621 and then enter the insertion holes 41. In this way, not only the insertion holes 41 of the respective drums 40 are protected, but also even if the individual wolf's teeth bars 62 are worn seriously, the individual wolf's teeth bars 62 are replaced with new ones directly, and the maintenance cost is relatively low.
At least two toggle mechanisms 70 for pressing the reels 40 may be provided at equal intervals on the outer circumferential side of the base 30 in order to facilitate separation of the armature winding from the reels 40 when the flat copper wire ends of the armature winding are pulled out of the insertion holes 41. The toggle clamp mechanism 70 includes a fixed base 71 connected to the frame 10, a pressing head assembly for pressing each drum 40, a handle 74, and a third link 75. The pressing head assembly comprises a pressing head 72 and a pressing head fixing plate 73 for fixing the pressing head 72, and the pressing head fixing plate 73 is rotationally connected with the fixing seat 71; the end of the handle 74 is rotatably connected to the holding-head fixing plate 73 and is rotatably connected to the fixing base 71 via a third link 75. Thus, when the flat copper wire end is pulled out of the jack 41, the handle 74 is rotated downwards to drive the pressing head 72 to press the rotary drum 40, so that the use is convenient.
The technical principle of the present invention is described above in connection with the specific embodiments. The description is made for the purpose of illustrating the general principles of the invention and should not be taken in any way as limiting the scope of the invention. Other embodiments of the invention will be apparent to those skilled in the art from consideration of this specification without undue burden.
