Description

Technical Field

[0001] This utility model relates to the technical field of flying fork winding machines, specifically a wire clamping and cutting assembly for a flying fork winding machine. Background Technology

[0002] A coil winding machine is a device that uses a high-speed rotating fork to wind coils. Through a precise control system, it can automatically and efficiently complete the coil winding work, greatly improving production efficiency.

[0003] In the prior art, such as the clamping and cutting device for a winding machine proposed in patent application number "CN202220806448.2", both blade ends are provided with V-shaped grooves, which divide the blade ends into left and right parts. The left part of the two blade ends is symmetrically sharpened to form a left cutting edge, and the right part of the two blade ends is symmetrically sharpened to form a right cutting edge. The double-edged scissor design allows for the cutting of two wire ends simply by moving left and right, which simplifies the control compared to the traditional method.

[0004] However, in the aforementioned patent application, the design of a double-edged scissor is used to cut two copper wires. However, the copper wires cannot be clamped before cutting, resulting in insufficient stability of the copper wires during cutting, which affects the success rate of cutting, causes the flying fork winding machine to be interrupted, and affects the overall work efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a wire clamping and cutting assembly for a flying fork winding machine to solve the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A wire clamping and cutting assembly for a flying fork winding machine includes a mounting plate. A cylinder is mounted on the upper surface of the mounting plate. A connecting pipe is fixedly connected to the bottom surface of the mounting plate. A second mounting base is fixedly connected to the outer wall of the connecting pipe. A first mounting base is fixedly connected to one end of the second mounting base. Upper and lower dies are movably mounted inside the connecting pipe, and one end of the cylinder is fixedly connected to the upper and lower dies. Blades are mounted on the outer walls of the upper and lower dies near their bottom ends. A connecting mechanism is provided between the upper end of the blades and the upper and lower dies. A wire pressing seat is movably mounted inside the connecting pipe near its bottom end. A spring is fixedly connected to the upper end of the wire pressing seat. A positioning pin is fixedly mounted on the outer wall of the wire pressing seat. A terminal block is fixedly connected to the bottom end of the connecting pipe.

[0008] Preferably, the connecting mechanism includes a slot, which is located on the inner wall of the upper and lower molds. An insert plate is inserted into the slot, and a groove is formed on the inner wall of the slot. Hollow tubes are fixedly connected to both inner side walls of the groove.

[0009] Preferably, each of the two hollow tubes has a rod inserted inside, and a spring is installed between one end of the rod and the inner wall of the hollow tube.

[0010] Preferably, a triangular block is fixedly connected to one end of each of the two insertion rods, and a connecting plate is fixedly connected to the upper surface of the insertion plate.

[0011] Preferably, a trapezoidal block is fixedly connected to the upper end of the connecting plate, and the trapezoidal block cooperates with two triangular blocks.

[0012] Preferably, both of the insert rods have a connecting rod fixedly connected to their outer walls.

[0013] Preferably, the connecting pipe and the outer walls of the upper and lower molds are provided with sliding grooves, and one end of the connecting rod passes through the two sliding grooves and is slidably connected to the connecting pipe. One end of each connecting rod is inserted with a fixing screw, and the outer wall of the connecting pipe is provided with a screw groove near the fixing screw, and the screw groove fits the fixing screw.

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

[0015] 1. This utility model uses a cylinder to drive the upper and lower dies and blades. The upper and lower dies are pushed by springs to move the wire pressing seat. The wire pressing seat contacts the terminal block and presses the copper wire inside the winding machine. At this time, the cylinder continues to move downward, and the spring pushes the blade downward to cut the copper wire. This achieves the structure of clamping the copper wire first and then cutting it. The whole operation is simple and smooth, ensuring the stability of the copper wire during the cutting process, improving the success rate of cutting, avoiding cutting failure and interruption of the flying fork winding machine, thereby improving the overall work efficiency. At the same time, it reduces the tension change of the copper wire during the cutting process and avoids the copper wire breaking at the non-cutting point due to excessive or insufficient tension.

[0016] 2. This utility model, by releasing the fixing of the connecting rods and moving the two connecting rods, causes the two triangular blocks to move and move out from under the trapezoidal block, releasing the obstruction of the trapezoidal block. The blade can then be removed, and another unused blade is inserted into the connecting tube, causing the insert plate mounted on the upper end of the blade to re-insert into the slot. The trapezoidal block, the two triangular blocks, and the second spring can obstruct the bottom surface of the trapezoidal block, confining the trapezoidal block within the groove, thereby fixing the position of the blade and completing the blade replacement. Through the above operation, when the blade is worn and needs to be replaced, the blade can be replaced without disassembling the entire clamping and cutting wire assembly, and no other tools are required, making the replacement operation more convenient.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] A wire clamping and cutting assembly for a flying fork winding machine, such as Figures 1-6As shown, the device includes a mounting plate 2, a cylinder 1 mounted on the upper surface of the mounting plate 2, a connecting pipe 10 fixedly connected to the bottom surface of the mounting plate 2, a mounting base 4 fixedly connected to the outer wall of the connecting pipe 10, a mounting base 3 fixedly connected to one end of the mounting base 4, upper and lower molds 5 movably mounted inside the connecting pipe 10, and one end of the cylinder 1 fixedly connected to the upper and lower molds 5, a blade 6 mounted near the bottom of the outer wall of the upper and lower molds 5, a connecting mechanism between the upper end of the blade 6 and the upper and lower molds 5, a wire pressing seat 8 movably mounted inside the connecting pipe 10 near the bottom, a spring 7 fixedly connected to the upper end of the wire pressing seat 8, a positioning pin 9 fixedly mounted on the outer wall of the wire pressing seat 8, and a terminal block 11 fixedly connected to the bottom of the connecting pipe 10.

[0028] In use, the wire clamping and cutting assembly is installed on the flying fork winding machine. During wire cutting, the cylinder 1 operates, pushing the upper and lower dies 5 and the blade 6 to move. The upper and lower dies 5 push the wire pressing seat 8 to move through the spring 7. The wire pressing seat 8 contacts the terminal block 11, pressing the copper wire inside the winding machine. At this time, the cylinder 1 continues to move downward, pushing the blade 6 downward to cut the copper wire through the extension space of the spring 7. This achieves the structure of clamping the copper wire first and then cutting it, ensuring the stability of the copper wire during the cutting process, improving the success rate of wire cutting, avoiding wire cutting failure, and preventing the flying fork winding machine from being interrupted, thereby improving the overall work efficiency. At the same time, it reduces the tension change of the copper wire during the cutting process, avoiding the breakage of the copper wire at the non-cutting point due to excessive or insufficient tension. The blade 6 has a round hole that fits with the positioning pin 9, which can further fix the position of the blade 6. The end face of the positioning pin 9 is an arc surface. When the blade 6 is pulled out, the inner wall of the round hole moves along the arc surface, allowing the positioning pin 9 to move out of the round hole.

[0029] The connecting mechanism includes a slot 19, which is located on the inner wall of the upper and lower molds 5. A plate 12 is inserted into the slot 19. A groove 22 is provided on the inner wall of the slot 19. Hollow tubes 13 are fixedly connected to the two inner side walls of the groove 22. Insert rods 14 are inserted into the two hollow tubes 13. A spring is installed between one end of the insert rod 14 and the inner wall of the hollow tube 13. A triangular block 17 is fixedly connected to one end of the two insert rods 14. A connecting plate 18 is fixedly connected to the upper surface of the plate 12.

[0030] A trapezoidal block 15 is fixedly connected to the upper end of the connecting plate 18, and the trapezoidal block 15 cooperates with two triangular blocks 17. A connecting rod 16 is fixedly connected to the outer wall of each of the two insert rods 14. The outer walls of the connecting tube 10 and the upper and lower molds 5 are provided with sliding grooves 20. One end of the connecting rod 16 passes through the two sliding grooves 20 and is slidably connected to the connecting tube 10. A fixing screw 21 is inserted into one end of each of the two connecting rods 16. A screw groove is provided on the outer wall of the connecting tube 10 near the end of the fixing screw 21. The screw groove fits with the fixing screw 21. By passing one end of the fixing screw 21 through the connecting rod 16 and rotating it into the screw groove, the position of the connecting rod 16 can be fixed.

[0031] Specifically, when the blade 6 wears out after long-term use and needs to be replaced, the fixing screws 21 on the two connecting rods 16 can be unscrewed to release the fixing of the connecting rods 16. Then, the two connecting rods 16 are moved along the two sliding grooves 20, causing the two insert rods 14 to move into the hollow tube 13 respectively. The spring 2 is compressed and contracted, thereby moving the two triangular blocks 17 to move out from under the trapezoidal block 15, releasing the obstruction of the trapezoidal block 15. At this time, the blade 6 can be moved down, so that the insert plate 12 moves out from the slot 19, and the trapezoidal block 15 and the connecting plate 18 move out from the groove 22, thereby releasing the fixing of the blade 6. The blade 6 can then be taken out. After the blade 6 is taken out, under the action of the spring 2's rebound force, the two triangular blocks 17 move to the initial position. Then, another unused blade 6 is inserted into the connecting tube 10, so that the blade 6 can be removed. The insert plate 12 installed on the upper end of the blade 6 is reinserted into the slot 19. The trapezoidal block 15 passes through the two triangular blocks 17. During this process, the trapezoidal block 15 moves upward along the inclined surface of the two triangular blocks 17, which can make the two triangular blocks 17 move away from each other until the trapezoidal block 15 completely passes between the two triangular blocks 17. Under the action of the spring return force, the two insert rods 14 can be moved out of the hollow tube 13, which can drive the two triangular blocks 17 to move closer to each other and return to the initial position. The bottom surface of the trapezoidal block 15 is blocked, and the trapezoidal block 15 is confined in the groove 22, thereby fixing the position of the blade 6 and completing the replacement of the blade 6. Through the above operation, when the blade 6 is worn and needs to be replaced, the replacement of the blade 6 can be completed without disassembling the entire wire clamping assembly, and no other tools are needed, making the replacement operation more convenient.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
