Description

Technical Field

[0001] This utility model relates to the field of transformer winding technology, specifically to an automatic transformer winding clamping device. Background Technology

[0002] A transformer consists of an iron core and coils. The coils have two or more windings. The winding connected to the power source is called the primary coil, and the remaining windings are called secondary coils. There is no electrical connection between the coils. The coils are wound with insulated copper wire. In the existing technology, the wire feeding frame of a transformer coil winding machine usually consists of a wire feeding frame and a winding shaft. The wire feeding shaft is driven by the winding tension of the wire feeding machine.

[0003] Patent CN213691749U proposes an automatic coil clamping device for transformer windings, which is installed on the coil and clamps the wires at any time to prevent them from loosening or crossing during the winding process, ensuring that they are arranged tightly and neatly. The clamping device is an automatic clamping mechanism with resistance provided by a compression spring, eliminating the need for workers to tap from the side, thus improving work efficiency.

[0004] Although the above technical solution achieves the clamping of the conductor during the winding process through the clamping device, the device is inconvenient to install and disassemble, and it is not convenient to quickly separate the clamping device from the coil after the winding is completed. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide an automatic transformer winding clamping device to solve the problems mentioned in the background. This invention has a novel structure. By limiting the movement of the moving plate through the clamping component and coordinating with the position of the copper wire feeding, the moving plate can be moved, so that the copper wire can be evenly wound on the winding shaft without overlapping or interlacing. After the moving plate moves to the end of the winding shaft, the clamping effect between the collar and the connecting end is released, which facilitates the quick separation of the clamping component from the winding shaft, making installation and disassembly more convenient.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic transformer winding clamping device includes a coil, a winding shaft installed at the center of the coil, a stop plate fixed at the other end of the winding shaft, a movable plate slidably sleeved on the surface of the winding shaft, and a clamping assembly located outside the movable plate on the winding shaft. The clamping assembly includes a collar, which is sleeved on the outside of the stop plate. An outer ring is provided on the outside of the collar, and four push rods are fixedly fixed at equal intervals on the surface of the outer ring. The push rods are in pressure contact with the outer surface of the movable plate. A first spring is sleeved on the surface of the push rods, and the other end of the first spring is fixedly connected to the collar. Copper wire is wound on the winding shaft between the coil and the movable plate. Two clamping frames are symmetrically provided on the outside of the collar, and the clamping frames are clamped and installed on the outer surface of the stop plate.

[0007] Furthermore, the clamping assembly also includes vertical rods, with vertical rods fixed to the top and bottom of the clamping frame respectively. The collar is slidably inserted with insert plates corresponding to the positions of the two vertical rods. Second springs are fixed to both sides of the outer end of the insert plates, and the other end of the second springs is fixedly connected to the collar.

[0008] Furthermore, the surface of the insert plate is provided with an inclined surface, and the top and bottom of the inclined surface are both flat. The top and bottom of the vertical rod slide along the flat surface and the inclined surface of the insert plate, respectively, and the vertical rod is slidably inserted into the surface of the collar.

[0009] Furthermore, a third spring is sleeved on the surface of the vertical rod, and the other end of the third spring is fixedly connected to the clamping frame.

[0010] Furthermore, a connecting end is rotatably mounted on the outer side of the abutment via a bearing, and the two clamping frames are held on the connecting end.

[0011] Furthermore, the front end of the movable plate is pressed against a semi-circular ring, and an elastic frame is fixed on the side of the semi-circular ring corresponding to the side where the copper wire is fed in. The lower end of the elastic frame is provided with an opening, and the copper wire slides through the elastic frame.

[0012] Furthermore, a connecting frame is fixed to the top of the clamping frame, and the vertical surface of the connecting frame is slidably inserted into the top of the outer ring, while the horizontal surface of the connecting frame is fixedly connected to the semi-circular ring.

[0013] Furthermore, four pins are symmetrically fixed on the side of the abutment facing the movable plate, and the movable plate has insertion holes at the positions corresponding to the pins.

[0014] The beneficial effects of this utility model are:

[0015] When the movable plate of this invention moves away from the abutment, the insert plate, under the elastic force of the second spring, passes through the collar, and the vertical rod contacts the bottom plane of the insert plate. Through the limiting of the insert plate and the vertical rod, the clamping frame is clamped on the surface of the connecting end, clamping and installing the pressing component. When the movable plate moves towards the abutment, it will contact the insert plate, thereby pushing the insert plate to move backward. The inclined surface at the bottom of the insert plate contacts the vertical rod, and the vertical rod, under the elastic force of the third spring, gradually drives the clamping frame to move upward. The clamping frame releases its clamping effect on the connecting end until the movable plate moves completely to the vicinity of the abutment, at which point the clamping component can be removed.

[0016] When the clamping frame is held on the connecting end, the semicircular ring contacts the top front end of the moving plate, and the elastic frame wraps around the surface of the copper wire. At this time, the copper wire can be horizontally transported by the wire feeder. The movement of the copper wire will drive the elastic frame to move, and the semicircular plate will also squeeze the moving plate to slide along the winding shaft, providing a position for the copper wire to be wound. At the same time, it can also maintain the effect of pressing the wound copper wire. When the clamping frame moves upward, the connecting frame will drive the semicircular plate to move upward and separate from the moving plate. The elastic frame can separate from the copper wire through the opening at the lower end, which facilitates the separation of the whole device from the coil and the winding shaft.

[0017] This invention allows the insert pin to be inserted into the insertion hole when the movable plate moves to the vicinity of the base plate, thus completing the insertion and positioning of the movable plate and the base plate, and cooperating with the wire reel to compress the copper wire.

[0018] Compared with the prior art, this utility model limits the movement of the moving plate by means of a clamping component, and assists the movement of the moving plate by means of the position of the copper wire feeding, so that the copper wire can be evenly wound on the winding shaft without overlapping or interlacing. After the moving plate moves to the end of the winding shaft, the clamping effect between the collar and the connecting end is released, which can facilitate the quick separation of the clamping component from the winding shaft, making installation and disassembly more convenient.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] Please see Figures 1 to 6 This utility model provides a technical solution: an automatic winding clamping device for transformers, including a coil 1, a winding shaft 11 installed at the center of the coil 1, a stop plate 13 fixed at the other end of the winding shaft 11, a movable plate 12 slidably sleeved on the surface of the winding shaft 11, and a clamping assembly 3 located outside the movable plate 12 on the winding shaft 11, the clamping assembly 3 including a collar 34, the collar 34 sleeved on the outside of the stop plate 13, an outer ring 31 located outside the collar 34, and four push rods 32 equidistantly fixed on the surface of the outer ring 31, the push rods 32 pressing against the outer surface of the movable plate 12, a first spring 33 sleeved on the surface of the push rods 32, and the other end of the first spring 33 fixedly connected to the collar 34, the winding shaft 11 being located between the coil 1 and the stop plate 12. Copper wire 2 is wound between the moving plates 12. Two clamping frames 35 are symmetrically provided on the outer side of the collar 34, and the clamping frames 35 are clamped and installed on the outer surface of the abutment plate 13. When using the device, the copper wire 2 is conveyed by the existing wire feeding frame, and the wire feeding frame can evenly wind the copper wire 2 onto the winding shaft 11 through the horizontal moving device. The wire spool 1 is installed on the winding station. The clamping component 3 is connected to one end of the winding shaft 11. The moving plate 12 is squeezed and limited by the top rod 32 and the first spring 33. The moving plate 12 and the wire spool 1 cooperate to press the copper wire 2 on the winding shaft 11. During the winding process, the moving plate 12 gradually moves backward along the winding shaft 11. After the moving plate 12 has completely moved to one end of the abutment plate 13, the clamping component 3 is separated from the winding shaft 11 and the clamping component 3 is removed separately.

[0028] In this embodiment, the clamping assembly 3 further includes vertical rods 312. Vertical rods 312 are fixed to the top and bottom of the clamping frame 35. Insert plates 39 are slidably inserted into the collar 34 corresponding to the positions of the two vertical rods 312. Second springs 310 are fixed to both sides of the outer ends of the insert plates 39, and the other ends of the second springs 310 are fixedly connected to the collar 34. An inclined surface 311 is provided on the surface of the insert plate 39, and the top and bottom of the inclined surface 311 are both flat. The top and bottom of the vertical rods 312 slide along the flat surface and inclined surface 311 of the insert plate 39, respectively, and the vertical rods 312 are slidably inserted into the surface of the collar 34. A third spring 313 is sleeved on the surface of the vertical rods 312, and the other end of the third spring 313 is fixedly connected to the clamping frame 35. A connecting end 16 is rotatably installed on the outer side of the abutment plate 13 via a bearing. The clamping frame 35 is clamped on the connecting end 16. When the moving plate 12 moves away from the abutment plate 13, the insert plate 39 passes through the collar 34 by the elastic force of the second spring 310. The vertical rod 312 contacts the bottom plane of the insert plate 39. Through the limiting of the insert plate 39 and the vertical rod 312, the clamping frame 35 is clamped on the surface of the connecting end 16 to clamp and install the pressing assembly 3. When the moving plate 12 moves toward the abutment plate 13, it will contact the insert plate 39, thereby pushing the insert plate 39 to move backward. The inclined surface 311 at the bottom of the insert plate 39 contacts the vertical rod 312. The vertical rod 312 gradually drives the clamping frame 35 to move upward by the elastic force of the third spring 313. The clamping frame 35 releases its clamping effect on the connecting end 16 until the moving plate 12 moves completely to the vicinity of the abutment plate 13. At this time, the clamping frame 35 is also completely released from the clamping position. At this time, the pressing assembly 3 can be removed.

[0029] In this embodiment, the top front end of the movable plate 12 is pressed against a semi-circular ring 37, and an elastic frame 38 is fixed to the side of the semi-circular ring 37 corresponding to the side where the copper wire 2 is fed. The lower end of the elastic frame 38 has an opening, and the copper wire 2 slides through the elastic frame 38. A connecting frame 36 is fixed to the top of the clamping frame 35, and the vertical surface of the connecting frame 36 is slidably inserted into the top of the outer ring 31. The horizontal surface of the connecting frame 36 is fixedly connected to the semi-circular ring 37. The semi-circular ring 37 moves synchronously with the upper clamping frame 35 through the connecting frame 36. When the clamping frame 35 is clamped on the connecting end 16, the semi-circular ring 37 and the movable plate 1... 2. The front end makes contact with the top, and the elastic frame 38 wraps around the surface of the copper wire 2. At this time, the copper wire 2 can be horizontally moved and conveyed by the wire feeder. The movement of the copper wire 2 will drive the elastic frame 38 to move, and the semi-circular plate will also squeeze the moving plate 12 to slide along the winding shaft 11, giving the copper wire 2 a winding position. At the same time, it can also maintain the effect of pressing the wound copper wire 2. When the clamping frame 35 moves upward, the connecting frame 36 will drive the semi-circular plate to move upward and separate from the moving plate 12. The elastic frame 38 can separate from the copper wire 2 through the opening at the lower end, which makes it convenient for the whole device to separate from the wire spool 1 and the winding shaft 11.

[0030] In this embodiment, four pins 14 are symmetrically fixed on the side of the support plate 13 facing the movable plate 12, and the movable plate 12 has insertion holes 15 at the positions of the pins 14. When the movable plate 12 moves to the vicinity of the support plate 13, the pins 14 can be inserted into the insertion holes 15 to complete the insertion and positioning of the movable plate 12 and the base plate, and cooperate with the wire reel 1 to press the copper wire 2.

[0031] When using the device, the copper wire 2 is fed by the existing wire feeder, and the wire feeder can evenly wind the copper wire 2 onto the winding shaft 11 through a horizontal moving device. The wire reel 1 is installed on the winding station, and the clamping assembly 3 is connected to one end of the winding shaft 11. The moving plate 12 is squeezed and limited by the top rod 32 and the first spring 33. The moving plate 12 cooperates with the wire reel 1 to press the copper wire 2 on the winding shaft 11. During the winding process, the moving plate 12 gradually moves backward along the winding shaft 11, and the two clamping frames 35 clamp it. At the connecting end 16, when the moving plate 12 moves away from the abutment plate 13, the insert plate 39, through the elastic force of the second spring 310, passes through the collar 34, and the vertical rod 312 contacts the bottom plane of the insert plate 39. Through the limiting action of the insert plate 39 and the vertical rod 312, the clamping frame 35 is clamped onto the surface of the connecting end 16, clamping and installing the pressing assembly 3. When the moving plate 12 moves towards the abutment plate 13, it contacts the insert plate 39, thereby pushing the insert plate 39 backward. The inclined surface 311 at the bottom of the insert plate 39 contacts the vertical rod 312. The vertical rod 312 gradually drives the clamping frame 35 to move upward through the elastic force of the third spring 313. The clamping frame 35 releases its clamping effect on the connecting end 16 until the moving plate 12 moves completely to the vicinity of the abutment plate 13. At this time, the clamping assembly 3 can be removed. The semi-circular ring 37 moves synchronously with the upper clamping frame 35 through the connecting frame 36. When the clamping frame 35 clamps the connecting end 16, the semi-circular ring 37 contacts the top front end of the moving plate 12, and at the same time, the elastic frame 38 wraps around the surface of the copper wire 2. At this point, the copper wire 2 can be horizontally conveyed by the wire feeder. The movement of the copper wire 2 will cause the elastic frame 38 to move, and the semi-circular plate will also squeeze the moving plate 12 to slide along the winding shaft 11, giving the copper wire 2 a winding position. At the same time, it can also maintain the effect of pressing the wound copper wire 2. When the clamping frame 35 moves upward, the connecting frame 36 will drive the semi-circular plate to move upward and separate from the moving plate 12. The elastic frame 38 can separate the copper wire 2 through the opening at the lower end, which makes it convenient for the whole device to separate from the wire spool 1 and the winding shaft 11.

It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.

[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
