Description

Technical Field

[0001] This utility model relates to the field of motor rotor technology, specifically a rotor winding device for motor production. Background Technology

[0002] The motor rotor is the rotating component of an electric motor. An electric motor consists of two parts: the rotor and the stator. It is a device used to convert electrical energy into mechanical energy and vice versa. During the manufacturing process, the motor rotor requires winding operations to ensure normal operation. These windings are typically used to generate a magnetic field and current inside the motor rotor, thereby converting electrical energy into mechanical energy.

[0003] For example, a motor rotor winding device (announcement number: CN222127869U) includes a worktable, the upper end of which is rotatably connected to a turntable... At least one spring damper is fixedly connected to the outer side of the fixing block, and the other end of the spring damper is fixed to the inner side of the limiting plate. The limiting plate can fix the motor rotor to prevent the rotor from shaking during winding and ensure the quality of winding.

[0004] Based on the search of the aforementioned patents and the discovery of existing equipment, the aforementioned equipment, when applied, uses the adjustment of the handrail to rotate the threaded rod to push the lifting plate down, thereby driving a series of components to fix the motor rotor. This operation involves the linkage of multiple components, and both installation and disassembly require manual continuous rotation of the threaded rod, making the operation steps quite cumbersome. In large-scale production scenarios, this would significantly increase the workload and time cost of operators, and reduce overall production efficiency. Therefore, we need to propose a rotor winding device for motor production. Utility Model Content

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution:

[0025] A rotor winding device for electric motor production includes a worktable 1;

[0026] Turntable 2 is rotatably mounted on top of worktable 1, and a fixing mechanism 3 for clamping and fixing the rotor is installed on turntable 2;

[0027] In an optional embodiment: the fixing mechanism 3 includes a cylinder 31, which is fixedly installed on the inner top of the turntable 2. A three-pronged plate 32 is fixedly connected to the bottom of the telescopic end of the cylinder 31. A lower mounting bracket 33 is fixedly connected to the top of each of the three ends of the three-pronged plate 32. An adjusting plate 34 is rotatably installed inside the lower mounting bracket 33 via a pin. An upper mounting bracket 35 is rotatably connected to one end of the adjusting plate 34 via a pin. A mounting plate 36 is fixedly connected to the top of the upper mounting bracket 35, and the bottom of the mounting plate 36 is slidably connected to the top of the turntable 2. A connecting plate 37 is fixedly installed on the top of the mounting plate 36, and a clamping plate 38 is fixedly installed on the top of one end of the connecting plate 37.

[0028] It should be noted that the fixing mechanism 3 adopts a three-jaw linkage structure driven by cylinder 31. Cylinder 31 is a precision cylinder with a magnetic ring, which can monitor the piston position in real time through a magnetic switch to achieve precise control of the clamping state. The three-pronged plate 32 is made of forged steel, with the three branches evenly distributed at 120° and rigidly connected to the cylinder extension end to ensure uniform force transmission. The adjusting plate 34 is made of high-strength alloy plate, and the pin holes at both ends are precision bored, with the clearance between the pin and the pin controlled between 0.005-0.01mm to ensure the flexibility and stability of rotation. The mounting plate 36 slides against the surface of the turntable. A high-precision guide rail structure is adopted to ensure straightness during movement. The clamping surface of the clamping plate 38 is designed to match the inner wall of the rotor, and wear-resistant rubber pads are attached to the surface to avoid damaging the rotor surface and increase friction to prevent slippage. The cylinder 31 drives the three-pronged plate 32, which in turn drives the three adjusting plates 34 to move synchronously from the center outward to abut and fix the inner wall of the rotor. This design makes the clamping force evenly distributed in multiple directions of the rotor. Compared with the traditional single-point or double-point clamping method, it can fix the rotor more stably and effectively prevent the rotor from shaking or displacing during the winding process.

[0029] In an optional embodiment: the top surface of the turntable 2 is provided with three sets of clearance grooves 4, and the three sets of upper mounting brackets 35 are respectively located inside the three sets of clearance grooves 4, and the outer wall of the upper mounting bracket 35 is slidably connected to the inner wall of the clearance groove 4.

[0030] It should be noted that the position of the clearance groove 4 corresponds one-to-one with the layout of the fixing mechanism 3. Its length and width are precisely designed according to the movement trajectory of the upper mounting frame 35 to ensure that the upper mounting frame 35 does not interfere with the groove wall within its maximum stroke range. The groove edge is rounded to avoid stress concentration and prevent hand scratches during operation. The fit clearance with the upper mounting frame 35 is controlled between 0.1-0.2mm, which ensures smooth sliding and provides a certain guiding function, providing sufficient space for the movement of the upper mounting frame 35 and avoiding structural interference with the turntable. The high-precision fit clearance and smooth surface reduce movement resistance and wear, and extend the service life of the components.

[0031] In an optional embodiment: a first slide rail 39 is fixedly installed on one side of the turntable 2 located in the clearance groove 4, a first slider 310 is slidably installed on the top outer wall of the first slide rail 39, and a mounting plate 36 is fixedly installed on the top of the first slider 310.

[0032] It should be noted that the first slide rail 39 adopts a high-precision linear guide rail with a rectangular cross-section. It is rigidly fixed to the turntable surface by bolts, and its parallelism error is within 0.01mm / m. The first slider 310 is equipped with multiple sets of precision balls, which achieve unlimited stroke through a circulating structure. The preload between the slider and the guide rail can be precisely controlled by adjusting screws. The mounting plate 36 is positioned with the slider by positioning pins and then fastened with bolts to ensure that the perpendicularity error between the mounting plate and the guide rail does not exceed 0.02mm. The guide rail surface is coated with long-lasting grease, and the slider end is equipped with a dustproof sealing ring, which can effectively prevent dust and oil from entering. The high rigidity and high precision of the linear guide rail ensure the straightness and stability of the sliding of the mounting plate 36, making the movement trajectory of the clamping plate 38 more accurate.

[0033] In an optional embodiment: a C-shaped frame 5 is slidably mounted on both sides of the workbench 1 located on the turntable 2. A winding motor 6 is fixedly mounted on the top of the C-shaped frame 5. One end of the output shaft of the winding motor 6 is fixedly connected to a flying fork bend rod 7, and the end of the flying fork bend rod 7 is fixedly connected to a flying fork arm 8.

[0034] It should be noted that the C-shaped frame 5 on both sides adopts a steel plate welded structure, and the welding stress is eliminated by aging treatment to ensure structural rigidity. The wound motor 6, the flying fork bending rod 7 and the flying fork arm 8 all refer to the existing technology in (announcement number: CN222127869U), and their working principle and structure are the same as the existing technology, so they will not be described here.

[0035] In an optional embodiment: the workbench 1 is symmetrically fixedly installed with two sets of second slide rails 9 at the bottom of the C-shaped frame 5, and a second slider 10 is slidably installed on the top of each of the two sets of second slide rails 9, and the C-shaped frame 5 is fixedly installed on the top of the two sets of second sliders 10.

[0036] It should be noted that the second slide rail 9 adopts a high-precision linear guide rail of the same specifications as the first slide rail 39. The two sets of guide rails are installed in parallel, and the parallelism error is controlled within 0.02mm / m. The number of second sliders 10 is determined according to the length of the convex frame 5 to ensure that each slider is subjected to uniform force. The sliders are connected to the convex frame 5 by T-bolts, which facilitates adjustment of the installation position. The double guide rail support improves the load-bearing capacity and motion stability of the convex frame 5, making it less prone to shaking when the winding mechanism moves at high speed.

[0037] In an optional embodiment: a guide cylinder 11 is fixedly installed on one side of the workbench 1 located on the C-shaped frame 5, and one end of the telescopic end of the guide cylinder 11 is fixedly installed on one side of the C-shaped frame 5.

[0038] It should be noted that the guide electric cylinder 11 is a ball screw servo electric cylinder with a repeatability of ±0.01mm. The thrust output can be precisely adjusted by the control system. A floating joint is provided at the connection between the electric cylinder and the shaped frame 5 to compensate for installation errors and avoid generating additional torque. The cylinder body is fixed to the worktable 1 by a high-strength bracket to ensure stability during operation. The electric cylinder is equipped with a stroke limit sensor to precisely control the movement range of the shaped frame 5. The servo electric cylinder drive realizes the automated and precise control of the shaped frame position, improving the automation level of the winding process. The high-precision positioning performance ensures the relative position accuracy between the winding mechanism and the rotor, improving the winding quality. The floating joint reduces the impact of installation errors on the equipment and extends the service life of the electric cylinder.

[0039] In an optional embodiment: a turntable bearing 12 is fixedly embedded at the center of the top of the worktable 1, the turntable 2 is fixedly installed on the top of the turntable bearing 12, and a rotary motor 13 is fixedly installed at the bottom of the worktable 1. The top of the output shaft of the rotary motor 13 passes through the worktable 1 and through the inner ring of the turntable bearing 12 and is fixedly installed at the bottom of the turntable 2.

[0040] It should be noted that the turntable bearing 12 uses a high-precision crossed roller bearing, which has the ability to simultaneously withstand radial force, axial force, and overturning moment. Its radial clearance is controlled between 0.005-0.01mm, ensuring the rotational accuracy of the turntable. The outer ring of the bearing is rigidly connected to the worktable 1 by bolts, and the inner ring is fitted to the flange at the bottom of the turntable 2. The rotating motor 13 is a servo motor with a brake, equipped with a precision harmonic reducer with a reduction ratio of 100:1, which can achieve an angle control accuracy of 0.01°. The motor output shaft is connected to the turntable 2 by a key to ensure the reliability of power transmission. The high rigidity and high precision of the crossed roller bearing ensure the stability and coaxiality of the turntable 2 during rotation, reducing radial runout during the winding process. The servo motor drive enables precise control of the turntable 2 angle, meeting the requirements of different winding processes for rotor position. The motor with a brake function can maintain the turntable position when the power is off or the machine is stopped, improving operational safety.

[0041] Working principle: When this utility model is in use, the cylinder 31 extends and retracts, driving the three-pronged plate 32 to descend. Through the lever action of the adjusting plate 34, the three sets of upper mounting brackets 35 are driven to slide synchronously along the clearance groove 4, so that the clamping plate 38 can open and close, completing the concentric clamping and fixing of the rotor.

[0042] The guide cylinder 11 drives the shaped frame 5 to slide along the second slide rail 9, precisely adjusting the relative position of the fly fork arm 8 and the rotor. The winding motor 6 drives the fly fork bending rod 7 and the fly fork arm 8 to rotate at high speed, realizing wire winding. At the same time, the rotating motor 13 drives the turntable 2 to rotate precisely through the turntable bearing 12, cooperating with the fly fork action to complete the winding of the rotor in multiple slots.

[0043] The control method in this application is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Furthermore, this application is mainly used to protect the structure and shape and their combination, so the control method and circuit connection will not be explained in detail in this application.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
