Description

Technical Field

[0001] This utility model relates to the technical field of iron core forming and processing equipment, and in particular to an automatic twisting machine. Background Technology

[0002] The iron core is the magnetic circuit part in transformers and motors. Its main function is to conduct magnetism, converting electrical energy from the primary circuit into magnetic energy, and then converting magnetic energy into electrical energy from the secondary circuit. Through its magnetic conduction, the iron core enhances the magnetic flux of the coil, thereby maximizing the conversion of electromagnetic power. During the processing of the iron core, it is necessary to wind wire around it, making multiple turns. This winding process involves twisting the wire. Most existing twisting devices use tooling to place the iron core on the tooling, and then the twisting is done manually. This method has low automation and low processing efficiency. The few automatic devices available cannot adjust the position of the twist joints. Publication number CN108655300B discloses an automatic twisting machine, which includes a base with a feeding device and a twisting device on it. The feeding device includes at least two thread holes. The twisting device includes a twisting component and a wire feeding component. The twisting component includes a correspondingly mounted main shaft and a first power assembly. The main shaft is hollow. The wire feeding component includes a mounting bracket, a wire feeding roller assembly, and a second power assembly. The mounting bracket is fitted onto one end of the main shaft. The wire feeding roller assembly and the second power assembly are mounted on the mounting bracket. The wire feeding roller assembly includes a pair of first rollers for clamping. The line connecting the center of symmetry of the thread hole and the center of symmetry of the first rollers is located on the center line of the main shaft. The second power assembly drives the pair of first rollers to rotate in opposite directions, thereby driving the metal wire forward. This twisting machine cannot twist iron cores and cannot adjust the spacing of the twisted sections. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an automatic twisting machine that is highly practical and has a high degree of automation.

[0004] To achieve the above objectives, the present invention provides the following solution: an automatic twisting machine, comprising a base, a rotating shaft, and a product seat. The rotating shaft is connected to the product seat and is used to drive the product seat to rotate. The product seat is used to place the workpiece to be twisted. The base is provided with a sliding guide rail and a second propulsion cylinder. A sliding seat is slidably connected to the sliding guide rail, and two grippers are connected to the sliding seat. The grippers are used to clamp copper wires. The second propulsion cylinder is connected to two copper wire stops, with one gripper corresponding to one copper wire stop. The copper wire stops are used to guide the copper wires to be conveyed to the workpiece on the product.

[0005] The beneficial effects of this utility model are as follows: It realizes automatic twisting of twisted wires. The twisting machine is equipped with a rotating shaft and a product seat. The product seat is used to place the workpiece to be twisted. Then, by setting a sliding guide rail, a sliding seat, and a clamp, the clamp clamps the copper wire. With the movement of the sliding seat, the two copper wires on the workpiece are tightened. Then, by setting a second propulsion cylinder and a copper wire stop, the first twisted section of the workpiece can be pushed to fit tightly against the workpiece. Finally, the rotating shaft drives the product seat and the workpiece to rotate, realizing automatic twisting of twisted wires. The spacing of the twisted sections can also be adjusted. The overall processing process has a high degree of automation, high processing efficiency, and strong practicality.

[0006] Furthermore, there are two sliding guide rails, which are arranged side by side with a gap between them, and one sliding guide rail is slidably connected to one sliding seat.

[0007] Furthermore, the gripper includes two clamping parts, which are used to clamp the copper wire together.

[0008] Furthermore, each of the sliding seats is equipped with a pneumatic finger, which is vertically positioned and connects to the two clamping parts. With the above structure, this invention achieves the clamping of copper wires.

[0009] Furthermore, the base is equipped with a first propulsion cylinder and two limiting frames. One of the limiting frames is located directly above a sliding guide rail. The first propulsion cylinder is horizontally positioned between the two sliding guide rails and is connected to a pressure plate. The pressure plate is connected to two sliding rods, one of which passes through a sliding seat and a limiting frame in sequence. With the above structure, this invention uses the pressure plate to drive the sliding seat and pneumatic finger to move.

[0010] Furthermore, each of the sliding rods is fitted with a return spring, one end of which abuts against the pressing sliding seat, and the other end of which abuts against the pressing limiting frame. With the above structure, this invention allows the return spring to push the sliding seat away from the limiting frame after the pressure plate moves away from the sliding seat.

[0011] Furthermore, the second propulsion cylinder is connected to a propulsion frame, which is rotatably connected to two copper wire blocks.

[0012] Furthermore, it also includes a stepper motor connected to the rotating shaft. With the above structure, this invention enables the rotating shaft, product base, and iron core to rotate, thus achieving the twisting effect.

[0013] Furthermore, the product base is inclined and has a mounting slot for placing the product.

[0014] Furthermore, a limiting cylinder is provided on the base. The limiting cylinder is vertically positioned, and an anti-rotation block is connected upward to the limiting cylinder. The anti-rotation block is located directly below the rotating shaft, and the anti-rotation block moves upward to clamp the rotating shaft, thereby limiting its rotation. With the above structure, this invention can limit the rotation of the rotating shaft when inserting or removing the iron core, facilitating the removal or insertion of the iron core.

[0022] See appendix Figure 1 To be continued Figure 4 As shown, an automatic twisting machine includes a base 1, a rotating shaft 21, a product seat 22, and a stepper motor. The rotating shaft 21 is connected to the product seat 22, and the stepper motor is connected to the rotating shaft 21. The rotating shaft 21 is used to drive the product seat 22 to rotate. The product seat 22 is used to place the workpiece to be twisted. The base 1 is provided with a sliding guide rail 11 and a second propulsion cylinder 14. A sliding seat 111 is slidably connected to the sliding guide rail 11. The sliding seat 111 is connected to two grippers 12, which are used to grip copper wire. The second propulsion cylinder 14 is connected to two copper wire stops 15, with one gripper 12 corresponding to one copper wire stop 15. The copper wire stops 15 are used to guide the copper wire to be transported to the workpiece on the product.

[0023] In this embodiment, there are two sliding guide rails 11, which are arranged side by side with a gap between them, and one sliding guide rail 11 is slidably connected to a sliding seat 111.

[0024] In this embodiment, the gripper 12 includes two gripping parts 121, which are used to grip the copper wire together. Each sliding seat 111 is provided with a pneumatic finger 112, which is arranged vertically and connects the two gripping parts 121.

[0025] In this embodiment, a first propulsion cylinder 13 and two limiting frames 16 are provided on the base 1. One limiting frame 16 is located directly above a sliding guide rail 11. The first propulsion cylinder 13 is arranged horizontally and is located between the two sliding guide rails 11. The first propulsion cylinder 13 is connected to a pressure plate 131. The pressure plate 131 is connected to two sliding rods 132. One sliding rod 132 passes through a sliding seat 111 and a limiting frame 16 in sequence. Each sliding rod 132 is fitted with a return spring. One end of the return spring abuts against the sliding seat 111 and the other end of the return spring abuts against the limiting frame 16.

[0026] In this embodiment, the second propulsion cylinder 14 is connected to a propulsion frame 141, and the propulsion frame 141 is rotatably connected to two copper wire blocks 15.

[0027] In this embodiment, the product base 22 is tilted and has a mounting groove 221 for placing the product.

[0028] In this embodiment, a limiting cylinder 17 is provided on the base 1. The limiting cylinder 17 is vertically arranged and an anti-rotation block 171 is connected to the limiting cylinder 17 upward. The anti-rotation block 171 is located directly below the rotating shaft 21. The anti-rotation block 171 moves upward to clamp the rotating shaft 21 to limit the rotation of the rotating shaft 21.

[0029] In this embodiment, the workpiece is an iron core. The specific twisting process is as follows: First, the iron core to be twisted is placed in the mounting slot 221 of the product base 22, so that the two copper wires of the iron core pass through the two copper wire stops 15 respectively and enter the two grippers 12. Then, the two pneumatic fingers 112 are activated. The pneumatic fingers 112 drive the two clamping parts 121 to move closer to each other until the two clamping parts clamp the copper wire together, thereby clamping the copper wire.

[0030] At this time, the first propulsion cylinder 13 is activated, and the piston rod of the first propulsion cylinder 13 extends to push the pressure plate 131 forward, so that the pressure plate 131 is away from the sliding seat 111. Then the return spring rebounds to push the sliding seat 111 away from the limit frame 16, thereby tightening the copper wire. Then the second propulsion cylinder 14 is activated, and the piston rod of the second propulsion cylinder 14 extends to push the propulsion seat 141 and the two copper wire stops 15 backward to push the first twisted joint of the twisted rope close to the iron core until the piston rod of the second propulsion cylinder 14 extends to its maximum stroke, so that the first twisted joint of the twisted rope is tightly attached to the iron core.

[0031] At this point, the stepper motor is started, driving the rotating shaft 21 and product seat 22 to rotate, thereby rotating the iron core and causing the two copper wires of the iron core to twist. Then, the piston rod of the second propulsion cylinder 14 is controlled to retract and reset, driving the propulsion seat 141 and the two copper wire stops 15 to move forward, thus widening the twist spacing at the beginning of the second twist. When the stepper motor drives the rotating shaft 21 to rotate to the set number of revolutions, the stepper motor stops rotating, and the two pneumatic fingers 112 are controlled to move the two clamping parts 121 away from each other to release the copper wires. Then, the piston rod of the first propulsion cylinder 13 is controlled to retract and reset, driving the pressure plate 131 to move backward, causing the pressure plate 131 to push the sliding seat 111 to move closer to the limit frame 16. The reset spring is compressed until the pressure plate 131 returns to its original position. At this point, the iron core can be removed from the product seat 22.

[0032] When it is necessary to insert or remove the iron core, the limiting cylinder 17 is activated, and the piston rod of the limiting cylinder 17 extends to push the anti-rotation block 171 to move upward until the anti-rotation block 171 engages and clamps the rotating shaft 21 to restrict the rotation of the rotating shaft 21. In this way, the iron core can be inserted into the product seat 22 or removed from the product seat 22.

[0033] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Any person skilled in the art can make more possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this utility model. Therefore, all equivalent changes made based on the concept of this utility model without departing from the content of the technical solution of this utility model should be covered within the protection scope of this utility model.
