Description

TECHNICAL FIELD

[0001] The utility model relates to a winding machine, concretely is a three -pin winding machine automatic deflection mechanism of swing range adjustable. BACKGROUND

[0002] The existing three -pin winding machine is mainly used for motor winding processing, and the key component is winding needle. In the traditional technology, winding needle usually swings along the preset motion track in the operation process, and the deflection angle and motion path are fixed values.

[0003] In the prior art, due to the fact that there are many types of motor products, the online slot structure and size of different models of motors have great differences, so that the ideal winding needle motion track also needs to be adjusted accordingly. However, since the existing three -pin winding machine adopts a fixed deflection mechanism, the deflection angle and motion track of the winding needle are determined at the time of design and manufacture, and cannot be adjusted or switched flexibly in real time according to the requirements of different motors. This fixed structure design has the following disadvantages in production practice:

[0004] 1. Poor adaptability: since the deflection angle of the existing three -pin winding machine is fixed, when producing different types of motors, the change of the motor slot size or shape often makes the original winding needle motion track no longer match the new process requirements, so it cannot be directly used. In order to meet the production requirements of different products, the mechanical structure must be greatly adjusted or redesigned, thereby greatly reducing the adaptability of the equipment.

[0005] 2. Low equipment transfer efficiency: in motor production, product models often need to be quickly switched according to market demand, and under the traditional technology, in order to adapt to different motor structures, mechanical components need to be re-adjusted or replaced, which not only increases the production preparation time, but also leads to low equipment transfer efficiency. The production line is often in a shutdown state during adjustment, which seriously affects the production continuity and economic benefits.

[0006] 3. Difficulty in debugging, high technical requirements for operators: since the deflection mechanism structure of the traditional winding machine is fixed, adjustment often requires manual rearrangement or fine adjustment of the mechanical structure. This process requires high professional and technical level of the debugging personnel, and since the mechanical structure adjustment involves the cooperation of multiple components, errors are likely to occur during the adjustment process, increasing the product failure rate and rework risk.

[0007] 4. Precision is difficult to guarantee: mechanical structure adjustment not only has a long cycle, but also is difficult to maintain the ideal motion track precision after each adjustment in the adjustment process. The traditional method mainly relies on manual experience and coarse adjustment, and it is difficult to achieve high-precision automatic control, which further affects the consistency and reliability of the winding product. Therefore, it is necessary to make further improvement. CONTENT OF THE UTILITY MODEL

[0047] In one embodiment, the hinge shaft 2 is rotatably installed in the hinge shaft seat 11 arranged on the main box 1.

[0048] Working principle:

[0049] The core working principle of the utility model is that through the cooperative action of the double guide rail, double sliding block linkage structure and servo driving system, the automatic and high-precision adjustment of the swing range of the winding needle is realized. The working principle is described in steps in combination with the drawings.

[0050] As shown in the drawings, Figure 1 The mechanism includes a main box 1, a swing arm 3, a first guide rail 4, a second guide rail 5, a first sliding block 41, a second sliding block 51, a first rotating shaft 6, a second rotating shaft 7 and a driving assembly.

[0051] The swing arm 3 is swingably installed on the main box 1 through the hinge shaft 2, the winding needle is fixed to the end of the swing arm 3, and the swing range determines the winding track.

[0052] The first guide rail 4 is fixed on the main box 1, and the first sliding block 41 is controlled to slide horizontally in the X-axis direction by the rotating screw rod 82 driven by the servo motor in the adjustment power device.

[0053] The second guide rail 5 is installed on the first sliding block 41, and the second sliding block 51 is driven to slide vertically along the second guide rail 5 in the Y-axis direction by the cam 91 in the swing power device.

[0054] The first rotating shaft 6 is fixed on the second sliding block 51 and can move with the second sliding block 51 and rotate around its own axis.

[0055] The second rotating shaft 7 is connected with the second bearing 62 installed on the top of the first rotating shaft 6, and the end is rigidly connected with the hinge shaft 2 through the shaft coupling 71, so that the movement of the second sliding block 51 is converted into the swing of the swing arm 3.

[0056] When the swing amplitude of the swing arm needs to be adjusted, the control system controls the servo motor to drive the first sliding block 41 to move horizontally, the power device drives the rotating lead screw 82 to rotate through the servo motor, and the lead screw nut 81 and the first sliding block 41 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 sliding block 41, and the horizontal displacement of the first sliding block 41 directly changes the relative position between the second rotating shaft 7 and the first rotating shaft 6, that is, the transmission lever ratio, so that the swing amplitude of the swing arm 3 is adjusted. Therefore, when the equipment is changed, only system setting is needed, and the cam or the limiting device does not need to be replaced.

[0057] After the transmission lever ratio is adjusted, the cam 91 of the swing power device is driven by the main shaft 9 to rotate in the limiting area. The edge of the cam 91 is embedded in the guide groove 55 of the guide wheel 54, and the second sliding block 51 is pushed to slide along the second guide rail 5 through rolling contact.

[0058] The movement of the second sliding block 51 is transmitted to the second rotating shaft 7 through the first rotating shaft 6. Since the second rotating shaft 7 is fixedly connected with the hinge shaft 2 through the shaft coupling 71, the rotation of the second rotating shaft 7 directly drives the hinge shaft 2 to rotate, and drives the swing arm 3 to swing.

[0059] For example, when a small swing amplitude slot motor needs to be produced:

[0060] The narrow slot parameters such as slot width 2mm are input in the control system, the servo motor drives the first sliding block 41 to move away from the hinge shaft 2, the length of the force arm of the second rotating shaft 7 is increased, and thus the swing amplitude of the swing arm 3 is reduced.

[0061] For example, when a large swing amplitude slot motor needs to be produced:

[0062] The deep slot parameters such as slot depth 10mm are input in the control system, the first sliding block 41 moves towards the hinge shaft 2, the length of the force arm of the second rotating shaft 7 is reduced, and thus the swing amplitude of the swing arm 3 is increased.

[0063] In summary, the present application realizes the accurate adjustment of the position of the first sliding block through the servo motor driving the rotating lead screw, and realizes the flexible adjustment of the swing amplitude of the swing arm by combining the transmission of the swing power device. The technical scheme not only realizes the automatic and accurate amplitude control, but also overcomes the shortcomings of the traditional technology in adaptability, production change efficiency, debugging difficulty and movement precision, so it can be widely used.

[0064] Obviously, the above embodiments are only examples for clearly illustrating the present application and are not intended to limit the present application. Based on the above description, other different forms of changes or variations can be made by those skilled in the art. Here, all the embodiments are not required to be exhausted. The obvious changes or variations derived therefrom are still within the protection scope of the claims of the present application.
