Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing technology, and in particular to a wire clamping mechanism and a winding machine. Background Technology

[0002] With the development of science and technology and the continuous progress of industrial applications, the requirements for power source motors are getting higher and higher. The improvement of motor performance depends not only on the progress of materials science, but also on the improvement of manufacturing process. Among them, the quality of motor winding directly affects the working efficiency and reliability of motor. Existing motor winding technology faces many challenges when dealing with thick-diameter enamel wire. Most of them use cylinder connecting parts to press the enamel wire to fix it. However, due to the increased contact area between the connecting parts and the enamel wire, the clamping force is relatively dispersed, resulting in poor clamping effect. This makes the enamel wire prone to slippage or falling off under high tension, affecting the accuracy and stability of winding. Utility Model Content

[0003] The main purpose of this utility model is to propose a wire clamping mechanism and a winding machine, which aims to solve the technical problems in the prior art of poor clamping effect on enamel wire and easy slippage or fall off of enamel wire under high tension.

[0004] To achieve the above objectives, the wire clamping mechanism proposed in this utility model includes:

[0005] Mounting base;

[0006] A first clamping seat is provided on the mounting base;

[0007] The second clamping seat is slidably disposed on the mounting base, and the first clamping seat and the second clamping seat are disposed opposite to each other;

[0008] A drive structure is provided on the mounting base; and

[0009] The connecting rod has one end rotating with the output end of the drive structure and the other end drivingly connected to the side of the second clamping seat away from the first clamping seat. The outer periphery of the end of the connecting rod near the second clamping seat is set in a cam shape. The output end of the drive structure moves along a first direction and drives the second clamping seat to move along a second direction through the connecting rod, so as to move closer to or away from the first clamping seat.

[0010] In one embodiment, the wire clamping mechanism further includes a first elastic element, which is disposed between the first clamping seat and the second clamping seat, and its two ends are elastically connected to the first clamping seat and the second clamping seat, respectively.

[0011] In one embodiment, the wire clamping mechanism further includes a connecting seat, which is mounted on the mounting base. The driving structure includes a fixed end and a driving end connected to the fixed end. The fixed end is rotatably disposed on the connecting seat, and the driving end is hinged to the connecting rod.

[0012] In one embodiment, the wire clamping mechanism further includes a second elastic element, which is disposed on the side of the first clamping seat facing the second clamping seat and the side of the second clamping seat facing the first clamping seat.

[0013] In one embodiment, the first clamping seat has a first notch on the side facing the second clamping seat, and the second clamping seat has a second notch on the side facing the second clamping seat. The second elastic member is respectively disposed at the first notch and the second notch, and protrudes from the first notch and the second notch.

[0014] In one embodiment, the second elastic element is a thermoplastic polyurethane elastomer.

[0015] In one embodiment, the wire clamping mechanism further includes a guide rail and a slider. The guide rail is disposed on the side of the mounting base where the first clamping seat is located, and the guide rail extends along the second direction. The slider is mounted on the side of the second clamping seat facing the mounting base and slides in cooperation with the guide rail.

[0016] In one embodiment, the wire clamping mechanism further includes a mounting plate disposed on the mounting base, the mounting plate having a through hole for the enameled wire to pass through.

[0017] In one embodiment, the wire clamping mechanism further includes a ceramic eye, which is disposed in the through hole, through which the enamel wire passes.

[0018] This utility model also proposes a winding machine, including the wire clamping mechanism described in any of the above claims.

[0019] In this invention, the wire clamping mechanism includes a mounting base. A first clamping seat and a second clamping seat protrude from one side of the mounting base. A driving structure and a connecting rod drive the second clamping seat to slide on the mounting base, moving it closer to or away from the first clamping seat. The enamel wire passes between the first and second clamping seats. When the driving structure drives the second clamping seat closer to the first clamping seat, the enamel wire is clamped. The clamping force can be adjusted according to the diameter of different enamel wires, making it suitable for producing products of various specifications. Furthermore, compared to the traditional method of using a cylinder to connect parts and press the enamel wire, the smaller contact area between the connecting rod and the second clamping seat provides a stronger and more concentrated clamping effect. To prevent the enamel wire from falling off or slipping, the outer periphery of the end that contacts the second clamping seat is cam-shaped and abuts against the second clamping seat. That is, when the drive structure drives the connecting rod to move, the connecting rod rotates and abuts against the second clamping seat at different positions of the cam, so that the second clamping seat is closer to the first clamping seat. The design of the cam shape makes the contact position between the connecting rod and the second clamping seat change at different rotation angles. As the connecting rod rotates, the contact point will move with the cam profile, thereby changing the force applied to the second clamping seat, i.e., dynamically adjusting the clamping force. Moreover, the cam can convert a small input force into a large output force, providing a stronger clamping effect and making it easier to handle enamel wires with thick diameter or high tension.

[0037] This utility model proposes a wire clamping mechanism and a wire winding machine.

[0038] Please see Figure 1 , Figure 2 and Figure 3In one embodiment of this utility model, the wire clamping mechanism includes:

[0039] Mounting base 100;

[0040] The first clamping seat 200 is provided on the mounting seat 100;

[0041] The second clamping seat 300 is slidably disposed on the mounting seat 100, and the first clamping seat 200 and the second clamping seat 300 are disposed opposite to each other;

[0042] Drive structure 400, located on mounting base 100; and

[0043] The connecting rod 500 has one end that rotates with the output end of the drive structure 400, and the other end that is driven to connect with the side of the second clamping seat 300 away from the first clamping seat 200. The outer periphery of the end of the connecting rod 500 near the second clamping seat 300 is set in the shape of a cam. The output end of the drive structure 400 moves along the first direction and drives the second clamping seat 300 to move along the second direction through the connecting rod 500, so as to move closer to or away from the first clamping seat 200.

[0044] In the technical solution of this utility model, the wire clamping mechanism includes a mounting base 100. A first clamping seat 200 and a second clamping seat 300 are protruding on one side of the mounting base 100. A driving structure 400 and a connecting rod 500 drive the second clamping seat 300 to slide on the mounting base 100, moving it closer to or away from the first clamping seat 200. The enamel wire passes between the first clamping seat 200 and the second clamping seat 300. When the driving structure 400 drives the second clamping seat 300 closer to the first clamping seat 200, the enamel wire can be clamped. The clamping force can be adjusted according to the diameter of different enamel wires, making it suitable for the production of products of various specifications. In addition, compared with the traditional method of pressing the enamel wire with a cylinder connecting part, the contact area between the connecting rod 500 and the second clamping seat 300 is small, which provides a stronger and more concentrated clamping force. The clamping effect prevents the enamel wire from falling off or slipping. One end of the clamping rod 500 has a cam-shaped outer periphery that abuts against the second clamping seat 300. When the drive structure 400 drives the connecting rod 500 to move, the connecting rod 500 rotates and abuts against the second clamping seat 300 at different positions of the cam, bringing the second clamping seat 300 closer to the first clamping seat 200. The cam shape design causes the contact position between the connecting rod 500 and the second clamping seat 300 to change at different rotation angles. As the connecting rod 500 rotates, the contact point moves along the cam profile, thereby changing the force applied to the second clamping seat 300, i.e., dynamically adjusting the clamping force. Furthermore, the cam can convert a smaller input force into a larger output force, providing a stronger clamping effect and making it easier to handle thicker diameter or high-tension enamel wires.

[0045] Specifically, the mounting base 100 can be a flat plate. A first clamping seat 200 is located on one side of the mounting base 100 and extends away from the plane of the mounting base 100. A second clamping seat 300 is located on the side of the mounting base 100 where the first clamping seat 200 is located, and is positioned opposite to the first clamping seat 200, creating a gap for the enameled wire to pass through. The drive structure 400 is mounted on the mounting base 100, and its output end is hinged to a connecting rod 500. The other end of the connecting rod 500 is rotatably connected to the mounting base 100 via a rotation. The end of the connecting rod 500 away from the drive structure 400 is cam-shaped, i.e., the end... The outer periphery of the connecting rod 500 is at a different position radius from the mounting base 100. The cam-shaped outer periphery of the connecting rod 500 abuts against the second clamping seat 300. That is, the driving structure 400 drives one end of the connecting rod 500 to move, so that the connecting rod 500 rotates around the connection point between the other end and the mounting base 100. This causes different positions of the cam-shaped part to contact the second clamping seat 300 and drive the second clamping seat 300 to move, so that the second clamping seat 300 moves closer to the first clamping seat 200 to clamp the paint wire. In this embodiment, the driving structure 400 is a cylinder, but it can also be a hydraulic cylinder or an electric telescopic cylinder or other linear drive component. There is no limitation on this.

[0046] Please refer to Figure 2 In an embodiment of this utility model, the wire clamping mechanism further includes a first elastic element 600, which is disposed between the first clamping seat 200 and the second clamping seat 300, and its two ends are elastically connected to the first clamping seat 200 and the second clamping seat 300, respectively.

[0047] Specifically, the first elastic element 600 can be a spring or other elastic material, without limitation. The first elastic element 600 is connected at both ends to the first clamping seat 200 and the second clamping seat 300. That is, when the second clamping seat 300 approaches the first clamping seat 200, the first elastic element 600 is compressed. However, when clamping a thicker diameter enameled wire, the distance between the first clamping seat 200 and the second clamping seat 300 needs to be increased. The second clamping seat 300 needs to move away from the first clamping seat 200. This is achieved by driving the connecting rod 500 to rotate via the drive structure 400, causing the connecting rod 500 to... The shorter diameter part of the cam-shaped part 00 is close to the second clamping seat 300. At this time, the connecting rod 500 is not in contact with the second clamping seat 300, so it is impossible to apply a force toward the first clamping seat 200 to the second clamping seat 300. Under the rebound of the first elastic element 600, the second clamping seat 300 moves away from the first clamping seat 200 to accommodate the thick-diameter enamel wire. Automatic reset is achieved by the first elastic element 600, which simplifies the mechanical structure. In addition, the first elastic element 600 can also play a buffering role during the clamping process, reducing the impact force caused by rigid contact and avoiding damage to the surface of the enamel wire.

[0048] Please refer to Figure 1and Figure 3 In an embodiment of this utility model, the wire clamping mechanism further includes a connecting seat 110, which is mounted on the mounting base 100. The driving structure 400 includes a fixed end and a driving end connected to the fixed end. The fixed end is rotatably disposed on the connecting seat 110, and the driving end is hinged to the connecting rod 500.

[0049] Specifically, a connecting seat 110 is provided on one side of the mounting base 100. The connecting seat 110 is fixed on the mounting base 100. Since the driving structure 400 in this embodiment adopts a cylinder, its cylinder body is rotatably connected to the connecting seat 110 as a fixed end. Taking this embodiment as an example, the connecting seat 110 is set vertically. When the second clamping seat 300 and the first clamping seat 200 are not clamped, the driving structure 400 remains vertical and the driving end moves downward. Since the end of the connecting rod 500 away from the driving structure 400 can only rotate around the mounting base 100 and will not move in the second direction, i.e., the horizontal direction, as the driving end extends, it drives the fixed end to rotate around the connecting seat 110 so that the driving end can continue to extend towards the direction of the connecting rod 500, drive the connecting rod 500 to rotate, and also drive the second clamping seat 300 to move in the second direction.

[0050] Please refer to Figure 2 and Figure 3 In an embodiment of this utility model, the wire clamping mechanism further includes a second elastic element 700, which is respectively disposed on the side of the first clamping seat 200 facing the second clamping seat 300 and the side of the second clamping seat 300 facing the first clamping seat 200.

[0051] Specifically, two second elastic elements 700 are provided and respectively installed on the opposite side of the first clamping seat 200 and the second clamping seat 300 for contacting the enamel wire. Since the second elastic element 700 has good friction, it can better grip the enamel wire, reduce slippage, and maintain stability and accuracy during the winding process. Furthermore, the second elastic element 700 has a certain degree of softness and elasticity, which can provide a buffering effect during clamping and avoid scratching or indenting the surface of the enamel wire. In one embodiment, the second elastic element 700 can be made of thermoplastic polyurethane elastomer or slingshot adhesive, but is not limited to these.

[0052] Please refer to Figure 2 In an embodiment of this utility model, the first clamping seat 200 is provided with a first notch 201 on the side facing the second clamping seat 300, and the second clamping seat 300 is provided with a second notch 301 on the side facing the second clamping seat 300. The second elastic member 700 is respectively disposed at the first notch 201 and the second notch 301, and protrudes from the first notch 201 and the second notch 301.

[0053] Specifically, the extension directions of the first notch 201 and the second notch 301 are both consistent with the length direction of the enamel wire. Correspondingly, the extension direction of the second elastic member 700 is also the length direction of the enamel wire. The second elastic member 700 is correspondingly disposed at the first notch 201 and the second notch 301, and protrudes from the first notch 201 and the second notch 301. The distance between the first clamping seat 200 and the second clamping seat 300 is greater than the distance between the two second elastic members 700. The first elastic member 600 is disposed between the first clamping seat 200 and the second clamping seat 300. When the second clamping seat 300 clamps the enamel wire close to the first clamping seat 200, it not only makes the second elastic members 700 on both sides of the enamel wire contact the enamel wire, but also provides space for the compression of the first elastic member 600. This avoids the situation where the distance between the two ends of the first elastic member 600 is the same as the distance between the two second elastic members 700, and the maximum compression of the first elastic member 600 is greater than the width of the enamel wire, resulting in the inability to clamp the enamel wire.

[0054] Please refer to Figure 2 In an embodiment of this utility model, the wire clamping mechanism further includes a guide rail and a slider. The guide rail is disposed on the side of the mounting base 100 where the first clamping seat 200 is provided, and the guide rail extends along the second direction. The slider is mounted on the side of the second clamping seat 300 facing the mounting base 100 and slides in cooperation with the guide rail.

[0055] Specifically, a guide rail and a slider are provided on the opposite side of the second clamping seat 300 and the mounting seat 100. In this embodiment, the guide rail is provided on the mounting seat 100 and extends along the sliding direction of the second clamping seat 300. The slider is provided on the side of the second clamping seat 300 facing the mounting seat 100 and is used to slide on the guide rail. This not only ensures that the second clamping seat 300 moves along the direction of the guide rail, reducing positional errors caused by free movement or offset, and providing guidance for the movement of the second clamping seat 300, but also reduces friction during the movement of the second clamping seat 300 and extends its service life.

[0056] Please refer to Figure 2 In an embodiment of this utility model, the wire clamping mechanism further includes a mounting plate 120, which is disposed on the mounting base 100 and has a through hole 121 for the enameled wire to pass through.

[0057] Specifically, after the first clamping seat 200 and the second clamping seat 300 clamp the enamel wire, the end of the enamel wire passes through the through hole 121 and reaches the next mechanism for winding or other processes. The through hole 121 provides a guiding path for the passage of the enamel wire, ensuring that the enamel wire reduces offset and bending when leaving the clamping mechanism, improving winding accuracy. In addition, the through hole 121 restricts the position of the enamel wire, reduces the risk of tangling, and improves the safety of operation.

[0058] Please refer to Figure 2In an embodiment of this utility model, the wire clamping mechanism further includes a ceramic eye 800, which is disposed in the through hole 121. The coated wire passes through the ceramic eye 800. The ceramic eye 800 has a low coefficient of friction, which can reduce friction and damage to the surface of the coated wire, ensure the quality of the coated wire, and avoid performance degradation of the coated wire due to mechanical damage. In addition, the ceramic eye 800 is detachably installed in the through hole 121, which makes it easy to replace the ceramic eye 800 with a suitable inner diameter according to the coated wire of different diameters, ensuring that the coated wire can pass through smoothly without loosening.

[0059] This utility model also proposes a winding machine, which includes a wire clamping mechanism. The specific structure of the wire clamping mechanism is as described in the above embodiments. Since this winding machine adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
