[0036] like Figure 1-7As shown, the present invention provides a copper bar fixing structure when a foil-wound transformer coil is wound, comprising: a winding shaft 1, a winding die 2, two copper bar positioning components 3 and a connecting component 4. The winding die 2 and the middle parts of the two copper bar positioning components 3 are penetrated by the winding shaft 1, the two copper bar positioning components 3 are respectively located on both sides of the winding die 2, and the connecting component 4 is used to fix the copper bar positioning components 3 at both ends of the winding die 2. The copper busbar positioning assembly 3 includes a winding drum 30, a first guide block 31, a slider 32, a first screw 33, a knob 34, and a second guide block 35. A square opening 301 is provided at the upper end of the winding drum 30. The first guide block 31 is located in the square opening 301. An inclined groove 310 is provided in the middle of the upper end of the first guide block 31. The inclined groove 310 is in the shape of an inverted triangle. The side of the first guide block 31 extends outward to form a slider 32. A slide groove 302 is provided at the front end of the winding drum 30 located at the square opening 301. The slide groove 302 is connected to the square opening 301 and the slide groove 302 is adapted to the slider 32. The slide groove 302 and the slider 32 are both vertically penetrated by the first screw 33. The first screw 33 is threadedly connected to the slider 32. The upper end of the first screw rod 33 extends to the outer upper end of the winding drum 30 and is connected with a knob 34. The second guide block 35 is located outside the square opening 301 and is detachably connected to the winding drum 30, so as to facilitate the disassembly and replacement of the second guide block 35 of different specifications according to the size of the copper bar. The copper bar can be positioned by cooperating with the first guide block 31 and the second guide block 35. When in use, the copper bar is passed through the second guide block 35, and the knob 34 is rotated, and the knob 34 drives the first screw rod 33 to rotate, and the first screw rod 33 drives the slider 32 to slide in the chute 302, and then the slider 32 drives the first guide block 31 to move upward in the square opening 301 door, so that the side of the chute 310 of the first guide block 31 squeezes and positions the bottom of the copper bar, and completes the fixing operation of the copper bar. The copper bar positioning assembly 3 can achieve the effect of fixing copper bars of different sizes.
[0037] In one embodiment, see Figure 1 The outer side of the first guide block 31 is marked with scales, which correspond to the distance between the two inclined sides of the inclined slot 310 at the same height on the first guide block 31. The first guide block 31 squeezes the copper bar from both sides of the bottom of the copper bar, and cooperates with the second guide block 35 to achieve the positioning operation. The side marked with scales is opposite to the second guide block 35 to avoid being blocked by the second guide block 35.
[0038] In one embodiment, see Figure 1 , Figure 2 and Figure 5The second guide block 35 is a frame structure, and the height of the gap in the middle of the frame is the thickness of the copper busbar. Both ends of the second guide block 35 extend outward to form a protrusion 350, and a through hole is provided on the protrusion 350, and a matching bolt is provided at the through hole. A plurality of screw holes matching the bolts are vertically arranged on the outer sides of both ends of the square opening 301, so that the second guide block 35 can adjust the corresponding fixed height according to the installation position of the copper busbar, thereby improving the scope of use. When in use, the second guide block 35 is fixed by passing the bolt through the through hole on the protrusion 350 and connecting it with the screw hole.
[0039] In one embodiment, see Figure 5 , the second guide block 35 is elastically connected with a squeeze plate 36 inside, and the upper end of the squeeze plate 36 is connected with a handle 37, which extends to the outside of the second guide block 35. When in use, the squeeze plate 36 is lifted by pulling the handle 37, and the copper bar is passed through the gap between the second guide block 35 and the squeeze plate 36 and adjusted to the position, and then the handle 37 is released, and the squeeze plate 36 is pushed under the elastic force to clamp and fix the copper bar, so as to avoid changing the scale of the second guide block 35, and directly limit the position of copper bars of different sizes. The squeeze plate 36 is slidably connected to the second guide block 35, and the second guide block 35 is used to limit the movement of the squeeze plate 36, so as to avoid the squeeze plate 36 from deflecting in the vertical plane and reduce the effect of positioning the copper bar. A spring 38 is connected between the upper end of the squeeze plate 36 and the inner top wall of the second guide block 35, and the spring 38 is used as a connector between the squeeze plate 36 and the second guide block 35 to reset the squeeze plate 36. The handle 37 is a U-shaped structure, and both side walls of the handle 37 pass through the second guide block 35 to further enhance the stability of the movement of the extrusion plate 36 .
[0040] In one embodiment, see Figure 1 , Figure 6 and Figure 7 The connection assembly 4 includes a plurality of retractors 40. A plurality of storage grooves 10 are provided on the side walls at both ends of the winding shaft 1. The winding shaft 1 is connected to a fixing block 11 at the bottom of the side of the storage groove 10. The fixing block 11 is rotatably connected to the winding shaft 1 and can be completely received in the storage groove 10 to prevent the fixing block 11 from protruding from the surface of the winding shaft 1 and hindering the installation and removal of the winding mold 2 and the winding drum 30. The fixing block 11 and the winding drum 30 are provided with a card slot adapted to the retractor 40 on the opposite sides thereof, which is used to limit the position of the two ends of the retractor 40 and prevent the retractor 40 from getting entangled and sliding sideways during connection.
[0041] In one embodiment, see Figure 1 , Figure 6 and Figure 7The retractor 40 includes a sleeve 401, a rotating ring 402 is connected to one end of the sleeve 401, a second screw 403 is slidably connected inside the sleeve 401, the rotating ring 402 is penetrated by the second screw 403 and is threadedly connected to the second screw 403, and positioning blocks 404 are provided on the opposite sides of the sleeve 401 and the second screw 403, and the positioning blocks 404 match the slots. When in use, the retractor 40 is placed between the fixed block 11 and the winding drum 30, and the rotating ring 402 is rotated to drive the second screw 403 to extend and extend from the sleeve 401, and the two positioning blocks 404 are respectively aligned with the slots on the fixed block 11 and the winding drum 30 on the same side and are inserted, so that the winding drum 30 is squeezed on the outside of the winding mold 2, and the winding mold 2 is clamped and positioned by multiple winding molds 2 to improve the stability of the fixation. The problem of affecting the winding of the winding mold 2 by inserting a fixing rod between the two winding drums 30 and locking them with bolts at both ends is avoided.
[0042] In one embodiment, see Figure 1 , Figure 6 and Figure 7 The outer surface of the swivel 402 is connected with a handle 405, which is rotatably connected to the swivel 402, and the rotation direction is perpendicular to the plane of rotation of the swivel 402. The outer surface of the sleeve 401 is connected with a snap ring 406, and the outer surface of the snap ring 406 is provided with a plurality of slots matching the handle 405 in a circumferential array. When in use, the handle 405 is rotated to be coplanar with the swivel 402, and the swivel 402 is rotated by the handle 405. After the rotation is completed, the handle 405 is rotated to clamp the handle 405 on the slot closest to the snap ring 406 to complete the positioning of the swivel 402. The setting of the swivel 402 reduces the problem of loosening of the telescope 40 in the fixing stage, and enhances the stability of the telescope 40.
[0043] In one embodiment, see Figure 1 and Figure 6 The side of the fixed block 11 away from the winding reel 30 is connected to a support rod 13, and the other end of the support rod 13 is connected to a moving block 14. The outer sides of the winding shaft 1 and the fixed block 11 are both provided with guide grooves matching the moving block 14. When in use, the fixed block 11 is rotated out of the storage groove 10, pushing the support rod 13 to rotate and move, and the other end of the support rod 13 rotates around the moving block 14 and pushes the moving block 14 to slide on the guide groove. When the fixed block 11 rotates to a position perpendicular to the winding shaft 1, the moving block 14 just moves to the end of the guide groove, and the support rod 13 supports the fixed block 11 to prevent the connection between the fixed block 11 and the winding shaft 1 from being broken due to excessive squeezing force of the telescopic device 40.
[0044] In one embodiment, see Figure 1The winding shaft 1 is a square shaft, and the middle parts of the winding mold 2 and the winding disk 30 are set as corresponding square connecting holes. The two ends of the winding shaft 1 are externally connected to the coil winding equipment, which is used to drive the winding shaft 1 to rotate and drive the winding mold 2 to rotate for coil winding.
[0045] The specific use process of the present invention is as follows: when in use, two winding reels 30 and the winding mold 2 are placed on the winding shaft 1 in a "sandwich" structure, the fixed block 11 is rotated to open, the retractor 40 is placed between the fixed block 11 and the winding reel 30, the retractor 40 is manually adjusted to extend, and the winding reel 30 is squeezed by the retractor 40 so that the winding reel 30 is squeezed on the side of the winding mold 2 to achieve the installation steps. According to the specifications of the selected copper bar and the winding mold 2, the second guide block 35 is installed on the winding reel 30, and the copper bar is passed through the second guide block 35. By turning the knob 34, the knob 34 drives the first screw 33 to rotate, and the first screw 33 drives the slider 32 to slide in the slide groove 302, and then the slider 32 drives the first guide block 31 to move upward in the square opening 301 door, so that the side of the inclined groove 310 of the first guide block 31 squeezes and positions the bottom of the copper bar, completing the fixation of the copper bar.
[0046] In summary, the present invention discloses a fixing structure for a copper bar during coil winding of a foil-wound transformer. By configuring a winding reel 30, a first guide block 31, a slider 32, a first screw 33, a knob 34, and a second guide block 35, the height of the copper bar can be limited by the second guide block 35, and the horizontal angle of the copper bar can be fixed by the first guide block 31, thereby achieving the effect of quickly and conveniently fixing the copper bar.
[0047] At the same time, a fixing block 11, an expander 40 and a winding drum 30 are also provided. The fixing block 11 is flipped out from the winding shaft 1, and the expander 40 is placed between the fixing block 11 and the winding drum 30 and extended, so that the expander 40 pushes and squeezes the winding drum 30, and the winding drum 30 is fixed to the outside of the winding mold 2, so that the winding drum 30 can be quickly installed, and the fixing methods of welding and bolt connection are avoided, which reduces the difficulty of operation, improves the operation efficiency, and facilitates disassembly.
[0048] Therefore, the present invention effectively overcomes various shortcomings in the prior art and has high industrial utilization value.
