Description

Technical Field

[0001] The present application relates to the field of welding technology, and particularly to a torque adjustment mechanism and a wire feeding device having the mechanism. Background Art

[0002] In the field of welding, especially in the field of automated welding, in order to meet the requirements of high-quality welding, a robotic welding system with a wire drawing function is usually adopted, that is, a welding torch with a wire drawing function and a wire feeding booster are used in combination as two wire feeding mechanisms for welding. However, in actual use, a semi-automatic welding or automatic welding wire feeding device usually used in normal times is usually used as a wire feeding booster device. Since a conventional semi-automatic welding or automatic welding wire feeding device has a complex structure, a large volume, a large weight, a high cost, and relatively complex control, it is not very suitable for application in a robotic welding system. To solve the above problems, a new type of wire feeding device dedicated to a robotic wire drawing welding system is developed.

[0003] The information disclosed in this background art section is only intended to enhance the overall understanding of the present application and should not be regarded as an admission or any form of suggestion that this information constitutes prior art already known to those of ordinary skill in the art. Summary of the Invention

[0004] The purpose of the present application is to provide a torque adjustment mechanism and a wire feeding device having the mechanism. By setting a torque adjustment structure on the wire feeding device, a wire feeding device with a simple structure, light weight, high reliability, low cost, and convenient operation is provided.

[0005] To achieve the above object, the present application is implemented by the following technical solutions:

[0006] A torque adjustment mechanism includes a first permanent magnet, a second permanent magnet, a bracket, and a wedge-shaped slider. The first permanent magnet is fixedly installed, the second permanent magnet is slidably installed, the second permanent magnet is fixedly connected to the bracket on the side, the wedge-shaped slider pushes the bracket, and an adjustment mechanism is connected above the wedge-shaped slider. The torque adjustment structure is installed on the wire feeding device.

[0007] By adopting the above solution, the position of the wedge-shaped slider is adjusted up and down through the adjustment mechanism, the gap between the first permanent magnet and the second permanent magnet is adjusted, so that the suction force between the two permanent magnets changes, and further the adjustment of the output torque is realized. When the wedge-shaped slider slides upward, the gap between the two permanent magnets becomes smaller, the suction force becomes larger, and the output torque becomes larger; on the contrary, when the wedge-shaped slider slides downward, the gap between the two permanent magnets becomes larger, the suction force becomes smaller, and the output torque becomes smaller. The structure is simple, convenient to control, and reduces the cost of the entire wire feeding process.

[0008] Optionally, the extrusion surface of the wedge-shaped slider is an inclined surface, and the inclined surface extrudes the bracket to move.

[0009] Optionally, the adjusting mechanism is an adjusting screw.

[0010] Optionally, a wire feeding device includes a motor, a frame, an input gear, an output gear, a wire feeding wheel and a torque adjusting mechanism. The motor is connected with the input gear through a bracket. A frame is arranged at one end of the motor. The input gear is connected with the output gear, and the other end of the output gear is connected with the wire feeding wheel.

[0011] Optionally, a first permanent magnet is fixedly installed on the motor shaft, a second permanent magnet is slidably connected to the input gear shaft, and the wedge-shaped slider is slidably installed on the frame.

[0012] Optionally, the second permanent magnet is slidably connected to the input gear shaft through a flange, and circumferential rotation is achieved between the flange and the bracket through a bearing.

[0013] Compared with the prior art, the beneficial effects achieved by this application are as follows:

[0014] 1. The torque adjusting device controls the distance between the first permanent magnet and the second permanent magnet through the movement of the wedge plate to adjust the torque. The structure is simple and the control is convenient.

[0015] 2. By using the torque adjusting device as a wire feeding assisting device, the whole wire feeding device has a simpler structure than the conventional semi-automatic welding or automatic welding wire feeding device, reducing the cost during the wire feeding process.

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way limits the present application and its application or use.

[0022] Embodiment 1:

[0023] A torque adjustment mechanism, as Figure 1 shown, includes a first permanent magnet 5, a second permanent magnet 6, a bracket 7, and a wedge-shaped slider 4. The first permanent magnet 5 is fixedly installed, and the second permanent magnet 6 is slidably installed. A bracket 7 is fixedly connected to the side of the second permanent magnet 6. The wedge-shaped slider 4 pushes the bracket 7. An adjustment mechanism is connected above the wedge-shaped slider 4. The torque adjustment structure is installed on the wire feeding device. By adjusting the position of the wedge-shaped slider 4 up and down through the adjustment mechanism, the gap between the first permanent magnet 5 and the second permanent magnet 6 is adjusted, so that the suction force between the two permanent magnets changes, thereby realizing the adjustment of the output torque. When the wedge-shaped slider 4 slides upward, the gap between the two permanent magnets becomes smaller, the suction force becomes larger, and the output torque becomes larger; on the contrary, when the wedge-shaped slider 4 slides downward, the gap between the two permanent magnets becomes larger, the suction force becomes smaller, and the output torque becomes smaller. The structure is simple, convenient to control, and reduces the cost of the entire wire feeding process.

[0024] As Figure 2 shown, the wedge-shaped slider 4 has an extrusion surface, and the extrusion surface is an inclined surface. The inclined surface extrudes the bracket 7 to move, driving the bracket 7 and the second permanent magnet 6 to move left and right, adjusting the gap between the first permanent magnet 5 and the second permanent magnet 6, so that the suction force between the two permanent magnets changes.

[0025] As Figure 1 shown, the wire feeding device includes a motor 1, a frame 2, an input gear 10, an output gear 11, a wire feeding wheel 12, and a torque adjustment mechanism. The motor 1 is connected to the input gear 10 through the bracket 7. A frame 2 is provided at one end of the motor 1. The input gear 10 is connected to the output gear 11, and the other end of the output gear 11 is connected to the wire feeding wheel 12.

[0026] As Figure 1 shown, a first permanent magnet 5 is fixedly installed on the shaft of the motor 1, a second permanent magnet 6 is slidably connected to the shaft of the input gear 10, and the wedge-shaped slider 4 is slidably installed on the frame 2, so that the wedge-shaped slider 4 can be controlled to move up and down.

[0027] Embodiment 2:

[0028] As Figure 1 shown, the adjustment mechanism is an adjustment screw 3, and the rotation of the adjustment screw 3 controls the up and down movement of the wedge-shaped slider 4.

[0029] As Figure 1As shown, the second permanent magnet 6 is slidably connected to the shaft of the input gear 10 through the flange 8, and the flange 8 and the bracket 7 are rotationally connected in a circumferential direction through the bearing 9.

It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0031] In addition, the terms "first", "second", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first", "second", etc. may explicitly or implicitly include one or more of such features. In the description of the present application, unless otherwise specified, the meaning of "a plurality" is two or more.

[0032] In the description of the present application, it should be noted that unless otherwise clearly specified and limited, the terms "installed", "connected", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood through specific situations.
