[0004] After the winding is completed, the copper wire needs to be wound around the hanging post of the stator rod, then the tail wire is cut off with scissors and clamped, and then the copper wire on the hanging post is manually removed, resulting in low work efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a five-axis brushless motor stator hook winding machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a five-axis brushless motor stator hook winding machine, including a frame, a front operating table on one side of the front of the frame, and a stator pressing assembly on the frame;

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figure 1-3 This utility model provides a technical solution: a five-axis brushless motor stator hook winding machine, including a frame 7, a front operating table 6 on one side of the front of the frame 7, and a stator pressing assembly 2 on the frame 7; the stator pressing assembly 2 includes a base plate fixedly installed on the frame 7, columns on both sides of the surface of the base plate, a connecting plate at the top between the two columns, a lifting cylinder 21 on the connecting plate, a horizontal plate 22 at the output end of the lifting cylinder 21, two symmetrical driven shafts 24 rotatably installed on the horizontal plate 22, the top of the driven shafts 24 extending above the horizontal plate 22, and a stator pressing rod 25 at the bottom of the driven shafts 24, and a stator seat 5 on the surface of the base plate corresponding to the position of the stator pressing rod 25; the stator to be wound is manually placed on the stator seat 5, and then the lifting cylinder 21 pushes the horizontal plate 22 downward, while the horizontal plate 22 drives the stator pressing rod 25 downward through the driven shafts 24, and the stator is fixed on the stator seat 5 by the stator pressing rod 25.

[0025] The stator rod 25 has a retractable wire hanging post at the top, and vertical plates are provided below both sides of the horizontal plate 22. A top rod cylinder 26 is provided at the bottom of the vertical plate corresponding to the position of the wire hanging post. The output end of the top rod cylinder 26 cooperates with the wire hanging post. A groove is opened on one side of the top of the stator rod 25. A telescopic spring is inserted into the groove. The wire hanging post is slidably inserted into the groove. The end of the wire hanging post located in the groove is fixedly connected to the telescopic spring. When the telescopic spring is in a free state, the free end of the wire hanging post extends to the outside of the groove for hanging the wire. When the top rod cylinder 26 squeezes the wire hanging post, it can squeeze the wire hanging post into the groove, which makes it easier for the copper wire on the wire hanging post to fall off.

[0026] Specifically, after the winding is completed, the push rod cylinder 26 acts on the hanging post, causing the hanging post to retract into the groove on the stator rod 25. The copper wire previously wound on it automatically falls off. Then, the horizontal plate 22 rises under the action of the lifting cylinder 21, and the stator rod 25 separates from the stator after the winding is completed. That is, the winding of a brushless motor stator is completed. There is no need to manually remove the copper wire from the hanging post, which improves work efficiency.

[0027] The groove has a sliding groove on its inner wall, and a slider that cooperates with the sliding groove is provided on one side of the hanging post surface. The hanging post is slidably inserted into the groove through the cooperation of the slider and the sliding groove.

[0028] The horizontal plate 22 has two symmetrical guide rods on its surface. The connecting plate has a guide sleeve at the position corresponding to the guide rod. The guide rod passes through the guide sleeve and is slidably connected to the guide sleeve. Through the cooperation of the guide rod and the guide sleeve, the lifting cylinder 21 can drive the horizontal plate 22 to reciprocate in the vertical direction.

[0029] The horizontal plate 22 is equipped with a positioning cylinder 23 corresponding to the position of the driven shaft 24. The output end of the positioning cylinder 23 is equipped with an arc-shaped plate that cooperates with the top of the driven shaft 24. The inner side of the arc-shaped plate is equipped with a rubber pad. When the driven shaft 24 needs to rotate, the arc-shaped plate does not contact the driven shaft 24, ensuring that the driven shaft 24 can rotate freely. When the driven shaft 24 does not need to rotate, the positioning cylinder 23 pushes the arc-shaped plate to contact the driven shaft 24, thereby fixing the position of the charging pile 24 so as to control the rotation stop position of the driven shaft 24 in time, thereby aligning the hanging post on the pressure stator rod 25 with the end of the top rod cylinder 26.

[0030] Among them, the lower surface of the horizontal plate 22 is provided with scissors 4 near the driven shaft 24. The specific structure of the scissors 4 is the same as that of the utility model patent with publication number CN222001697U, and will not be described in detail in this application.

[0031] The frame 7 is equipped with a five-axis linkage assembly 1, which includes a Z-axis base and a pressure stator assembly 2 located in front of the Z-axis base. The Z-axis base is equipped with a winding assembly 3 that can slide up and down. This winding assembly 3 is consistent with the utility model patent with publication number CN220234442U, and will not be described in detail in this application.

[0032] The Z-axis base includes a fixed plate fixedly mounted on the back of the frame 7. A Z-axis servo motor is mounted on the top of the fixed plate. A lifting screw is mounted on the output end of the Z-axis servo motor. A nut sleeve is threaded onto the lifting screw. A mounting plate is mounted on the nut sleeve. The winding assembly 3 is fixedly connected to the mounting plate. The Z-axis servo motor can drive the lifting screw to rotate. During the rotation of the lifting screw, the mounting plate will move up and down along the lifting screw, thereby adjusting the position of the winding assembly 3 in the vertical opposite direction.

[0033] The fixed plate has two symmetrical vertical slide rails on its surface, and the lifting screw is located between the two vertical slide rails. The winding assembly 3 has a pulley on its rear side that cooperates with the vertical slide rails. The pulley cooperates with the vertical slide rails to ensure that the winding assembly 3 can move up and down along the lifting screw.

[0034] Working principle: When using the brushless motor stator winding machine, before starting the winding process, the copper wire is first passed through the wire tensioner, extended down and passed through the wire nozzle under the winding rod, and then clamped by the scissor clamp. The stator to be wound is then manually placed on the stator base 5. Then, the lifting cylinder 21 pushes the horizontal plate 22 downward, and at the same time, the horizontal plate 22 drives the stator pressing rod 25 downward through the driven shaft 24. The stator is fixed on the stator base 5 by the stator pressing rod 25. At this point, the Z-axis base moves forward from the origin according to the parameters, while simultaneously driving the winding assembly 3 to descend. Once it reaches a safe height, it winds the wire along the hanging post on the stator rod 25, securing the wire end to the hanging post. The winding rod then continues to descend in the first inlet slot at the center of the stator, stopping at a safe height at the bottom of the stator. Following the parameters, the stator rotates to the adjacent second slot, and the winding assembly 3, carrying the winding rod, rises and stops at a safe height above the stator. The stator then rotates again according to the parameters, deflecting and stopping above the first slot, completing one turn of winding. This cycle repeats sequentially, winding the wire in sequence. After completing the first slot, the winding action is repeated until all slots are wound. At this point, the winding assembly 3 on the Z-axis base rises and winds the copper wire onto the hanging post. The winding rod's wire nozzle then winds the copper wire onto the hanging post, and the wire is then cut and clamped by the shears of the scissors 4. Here, the top rod cylinder 26 acts on the wire hanging post, causing the wire hanging post to retract into the groove on the stator rod 25. The copper wire previously wound on it automatically falls off. Then, the horizontal plate 22 rises under the action of the lifting cylinder 21, and the stator rod 25 separates from the stator after winding, that is, the winding of a brushless motor stator is completed.

[0035] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
