Description

Technical Field

[0001] The present invention relates to a winding machine, specifically an automatic swing mechanism of a three-needle winding machine with adjustable swing amplitude. Background Art

[0002] Existing three-needle winding machines are mainly used for motor winding processing, and their key component is the winding needle. In traditional technology, the winding needle usually swings along a preset movement trajectory during operation, and its swing angle and movement path are both fixed values.

[0003] In the existing technology, due to the large variety of motor products, there are significant differences in the slot structures and dimensions of different models of motors, resulting in the need for corresponding adjustments to the ideal movement trajectory of the winding needle. However, since the existing three-needle winding machines adopt a fixed swing mechanism, the swing angle and movement trajectory of the winding needle are determined during design and manufacturing, and cannot be adjusted in real time or switched flexibly according to the requirements of different motors. Such a fixed structural design has the following disadvantages in production practice: 1. Poor adaptability: Due to the fixed swing angle of the existing three-needle winding machines, when producing different types of motors, changes in the size or shape of the motor slots often make the original movement trajectory of the winding needle no longer match the new process requirements, and thus it cannot be directly used. To meet the production requirements of different products, the mechanical structure must be significantly adjusted or redesigned, which greatly reduces the adaptability of the equipment.

[0004] 2. Low equipment production changeover efficiency: In motor production, it is often necessary to quickly switch product models according to market demand. Under traditional technology, to adapt to different motor structures, mechanical components need to be readjusted or replaced, which not only increases the production preparation time but also results in low equipment production changeover efficiency. The production line is often in a shutdown state during the adjustment period, seriously affecting production continuity and economic benefits.

[0005] 3. Difficult debugging and high technical requirements for operators: Due to the fixed structure of the swing mechanism of traditional winding machines, adjustments often rely on manual rearrangement or fine-tuning of the mechanical structure. This process requires a high level of professional technical skills for the debugging personnel. At the same time, since the adjustment of the mechanical structure involves the cooperation of multiple components, errors are extremely likely to occur during the adjustment process, increasing the product defect rate and rework risk.

[0006] 4. Difficulty in ensuring accuracy: The adjustment of the mechanical structure not only has a long cycle but also is difficult to maintain the ideal movement trajectory accuracy after each adjustment during multiple adjustments. Traditional methods mainly rely on manual experience and rough adjustment, and it is difficult to achieve high-precision automatic control, further affecting the consistency and reliability of the wound products. Therefore, it is necessary to make further improvements to it. Summary of the Invention

[0007] The object of the present invention is to overcome the drawbacks of the existing technologies and provide a yaw mechanism with a simple structure, convenient operation and high precision, so as to realize the automatic adjustment of the movement trajectory of the winding needle during the production process of different motor products, and improve the production line conversion efficiency and product quality, which is an automatic yaw mechanism of a three-needle winding machine with adjustable swing amplitude.

[0008] The object of the present invention is achieved in the following way: An automatic yaw mechanism of a three-needle winding machine with adjustable swing amplitude, which includes a main chassis, and a swing arm is swingably installed on the main chassis through a hinge shaft; It further includes a first guide rail installed on the main chassis, a first slider is installed on the first guide rail, and the first slider is driven by an adjustment power device to slide along the first guide rail; It further includes a second guide rail installed on the first slider, a second slider is installed on the second guide rail, and the second slider is driven by a yaw power device to slide along the second guide rail; A first rotating shaft is provided on the second slider, and the first rotating shaft can rotate relative to the second slider; A second rotating shaft is installed on the first rotating shaft through a second bearing seat, and the second rotating shaft is connected to the hinge shaft; When the second slider moves, through the cooperation of the first rotating shaft and the second rotating shaft, the hinge shaft is driven to rotate, realizing the swing of the swing arm.

[0009] Further: The adjustment power device is a screw rod fixing seat fixed on the main chassis, and a screw rod nut fixed on the first slider. The rotating screw rod passes through the screw rod fixing seat and is connected to the screw rod nut; The outer end of the rotating screw rod is connected to a servo motor, and the servo motor drives the rotating screw rod to rotate.

[0010] Further: The yaw power device includes a first guide wheel seat and a second guide wheel seat installed on the second slider, and a limiting area for restricting the movement of the cam is formed between the first guide wheel seat and the second guide wheel seat; A main shaft is also rotatably installed on the main chassis, a cam is installed on the main shaft, and a yaw motor drives the cam to rotate within the limiting area through the main shaft, and drives the second slider to reciprocate by the contact between the cam and the limiting area.

[0011] Further: Guide wheels are installed on the first guide wheel seat and the second guide wheel seat, and the guide wheels are connected to the cam.

[0012] Further: An inward concave guide groove is provided on the outer circumference of the guide wheel, and the cam slides within the guide groove.

[0018] The beneficial effects of the present invention are as follows: 1. The structure is simple, the production cost is low, and the market competitiveness is improved.

[0019] 2. The system setting is simple and the adjustment is convenient. Only by setting the system, driving the rotating screw to rotate by the servo motor, the first slider can be driven to move along the first guide rail, thereby changing the relative position between the second rotating shaft and the first rotating shaft, and thus adjusting the power fulcrum of the second rotating shaft to achieve the adjustment of the swing amplitude of the swing arm. This design avoids the complex steps of substantial modification required by the traditional mechanical structure and simplifies the adjustment process.

[0020] It has strong adaptability and meets the requirements of different motor wire grooves.

[0021] 3. By precisely controlling the power fulcrum of the second rotating shaft through the servo motor, the swing amplitude of the swing arm can be precisely controlled, and automatic adjustment can be achieved according to the structural changes of different motor wire grooves without the need for re-design or substantial modification of the mechanical mechanism, thereby greatly improving the versatility and production adaptability of the equipment.

[0022] 4.

[0033] In one embodiment: an inward concave guide groove 55 is arranged on the outer circle of the guide wheel 54, and the cam 91 slides within the guide groove 55.

[0034] In one embodiment: the cam 91 is sleeved outside the spline shaft 92 of the main shaft 9 through a spline hole 56.

[0035] In one embodiment, a first bearing block 57 is provided on the second slider 51, a first bearing 58 is installed in the first bearing block 57, and the first rotating shaft 6 is installed in the first bearing 58 and rotates relative to the second slider 51.

[0036] In one embodiment, a second bearing 62 is installed on the first rotating shaft 6, and the second bearing 62 is slidably sleeved outside the second rotating shaft 7.

[0037] In one embodiment, a coupling 71 is provided at the other end of the second rotating shaft 7, and the coupling 71 is connected to the hinge shaft 2.

[0038] In one embodiment, a hinge shaft seat 11 is provided on the main chassis 1, and the hinge shaft 2 is rotatably installed in the hinge shaft seat 11.

[0039] Working principle: The core working principle of the present invention is to realize the automatic and high-precision adjustment of the swing amplitude of the winding needle through the coordinated action of the double guide rails, double slider linkage structure, and servo drive system. The following describes its working principle step by step in combination with the attached drawings.

[0040] As Figure 1 shown, this mechanism includes a main chassis 1, a swing arm 3, a first guide rail 4, a second guide rail 5, a first slider 41, a second slider 51, a first rotating shaft 6, a second rotating shaft 7, and a drive assembly.

[0041] Among them, the swing arm 3 is swingably installed on the main chassis 1 through the hinge shaft 2, and the winding needle is fixed to the end of the swing arm 3, and its swing amplitude determines the winding trajectory.

[0042] Among them, the first guide rail 4 is fixed on the main chassis 1, and the first slider 41 is controlled to slide horizontally in the X-axis direction by the rotating lead screw 82 driven by the servo motor in the adjustment power device.

[0043] Among them, the second guide rail 5 is installed on the first slider 41, and the second slider 51 is driven by the cam 91 in the yaw power device to slide vertically in the Y-axis direction along the second guide rail 5.

[0044] Among them, the first rotating shaft 6 is fixed on the second slider 51 and can move with the second slider 51 and rotate around its own axis.

[0045] The second rotating shaft 7 is connected to the second bearing 62 installed on the top of the first rotating shaft 6, and the end is rigidly connected to the hinge shaft 2 through the coupling 71, converting the movement of the second slider 51 into the swing of the swing arm 3.

[0046] Among them, when it is necessary to adjust the swing amplitude of the swing arm, the control system controls the servo motor to drive the first slider 41 to horizontally displace, adjusts the power device to drive the rotating lead screw 82 to rotate through the servo motor, and drives the lead screw nut 81 and the first slider 41 to slide along the first guide rail 4. The servo motor receives the target swing amplitude parameter through the numerical control system, automatically calculates the target position of the first slider 41, and the horizontal displacement of the first slider 41 directly changes the relative position between the second rotating shaft 7 and the first rotating shaft 6, that is, the transmission lever ratio, thereby adjusting the swing amplitude of the swing arm 3. Therefore, when the equipment changes production, only system settings are required, and there is no need to replace the cam or the limit device.

[0047] Among them, after the transmission lever ratio is adjusted, the cam 91 of the yaw power device is driven by the main shaft 9 and rotates within the limit area. The edge of the cam 91 is embedded in the guide groove 55 of the guide wheel 54, and the second slider 51 is pushed to slide along the second guide rail 5 through rolling contact.

[0048] Among them, the movement of the second slider 51 is transmitted to the second rotating shaft 7 through the first rotating shaft 6. Since the second rotating shaft 7 is fixedly connected to the hinge shaft 2 through the coupling 71, the rotation of the second rotating shaft 7 directly drives the hinge shaft 2 to rotate, driving the swing arm 3 to swing.

[0049] For example, when it is necessary to produce a small swing amplitude slot motor: Narrow slot parameters such as a slot width of 2 mm are input into the control system, and the servo motor drives the first slider 41 to move away from the hinge shaft 2, increasing the lever arm length of the second rotating shaft 7, thereby reducing the swing amplitude of the swing arm 3.

[0050] For example, when it is necessary to produce a large swing amplitude slot motor: Deep slot parameters such as a slot depth of 10 mm are input into the control system, the first slider 41 moves towards the hinge shaft 2, reducing the lever arm length of the second rotating shaft 7 and increasing the swing amplitude of the swing arm 3.

[0051] To sum up, the present invention realizes the precise adjustment of the position of the first slider by adopting a servo motor to drive a rotating lead screw, and combines a yaw power device to transmit motion, realizing the flexible adjustment of the swing amplitude of the swing arm. This technical solution not only realizes automatic and precise amplitude adjustment control, but also overcomes the deficiencies of traditional technologies in terms of adaptability, production change efficiency, debugging difficulty, and motion accuracy. Therefore, it can be widely promoted and used.

[0052] Obviously, the above embodiments are only examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the claims of the present invention.
