Description

Technical Field

[0001] This utility model relates to the field of winding equipment technology, and more specifically, to a winding device for an electric motor rotor. Background Technology

[0002] Winding equipment is an important step in the motor manufacturing process. These devices can efficiently complete the winding work, ensuring the performance and quality of the motor.

[0003] However, existing winding equipment has the following problems when in use:

[0004] Traditional motor rotor winding equipment often uses a single-end fixed rotor clamping structure. During the winding process, the rotor is prone to shaking due to centrifugal force and enameled wire tension, which leads to deviations in the number of winding turns and wear of the insulation layer, affecting the stability of the motor.

[0005] This invention can accurately clamp the rotor and achieve synchronous winding of two wires, improve the wire density and winding efficiency, and ensure uniform winding of the enameled wire. Summary of the Invention

[0006] The present invention aims to solve the technical problems mentioned in the background art and provide a winding device for motor rotor.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a winding device for a motor rotor, comprising: a workbench, a placement frame fixedly mounted on the front of the workbench, a fixed seat fixedly mounted below the placement frame, an mounting plate fixedly mounted below the fixed seat, and a fixed plate fixedly mounted on the front of the workbench. The placement frame, the fixed seat, and the mounting plate are all mounted on the fixed plate. A clamp seat is rotatably connected to the front of the fixed seat, and a front clamp seat is rotatably connected to the front of the mounting plate. The front clamp seat and the clamp seat are matched.

[0008] A further preferred embodiment: A control box is fixedly installed on the upper part of the workbench, a display screen is fixedly installed on the front of the control box, a switch is fixedly installed on the right side of the display screen, and several control knobs are fixedly installed below the display screen.

[0009] A further preferred embodiment: a connecting rod is fixedly installed at the rear end of the placement frame, a chassis is fixedly installed at the rear end of the connecting rod, and the chassis is fixedly installed on a fixed plate.

[0010] A further preferred embodiment: a connecting plate is fixedly installed on the front of the placement rack, a wire wheel plate is fixedly installed on the front of the connecting plate, and a wire wheel is fixedly installed on the front of the wire wheel plate.

[0011] A further preferred embodiment: the number of the spools is two, and their wire-holding ends are respectively set one up and one down.

[0012] A further preferred embodiment: a motor is fixedly installed on the front of the fixed base, the output end of the motor is fixedly connected to the clamp base, a slide rail is fixedly installed in front of the motor, an upper clamping block is slidably connected on the slide rail, and the slide rail is fixedly installed on the rear side of the upper end of the clamp base.

[0013] A further preferred embodiment: a second motor is fixedly mounted on the left end of the mounting plate, and a connecting rod is rotatably mounted on the right end of the mounting plate, the connecting rod being fixedly connected to the output end of the second motor.

[0014] A further preferred embodiment: a rotating rod is fixedly connected to the other end of the connecting rod, a front clamp is fixedly connected to the surface of the rotating rod, and a front clamp block is fixedly installed on the upper end of the front clamp.

[0015] A further preferred embodiment: the front clamping block is configured to be matched with the clamping seat. Beneficial effects

[0016] 1. By setting up a slide rail, an upper clamping block, and a front clamping block, the slide rail provides precise sliding guidance for the upper clamping block, enabling it to move smoothly along a fixed trajectory. This ensures the positional accuracy when clamping the rotor and avoids winding deviations caused by shaking. The upper clamping block and the front clamping block cooperate to form a "front and rear clamping" structure, which limits and fixes the rotor from both ends. The sleeve design at the rear end of the front clamping block can tightly nest the rotor shaft, enhancing the axial fixation effect and effectively resisting the centrifugal force and enameled wire tension generated by the rotor rotation during winding. This ensures that the rotor remains stable when rotating at high speed. This structure not only improves the convenience of rotor clamping, allowing for quick fixation without complex alignment, but also reduces human operation errors through mechanical limiting, ensuring that the rotor position remains accurate throughout the winding process. This, in turn, improves the uniformity and consistency of enameled wire winding and ensures the winding quality of the motor rotor.

[0017] 2. By setting up a wire wheel, which is mounted on the wire wheel plate and fixed to the placement frame via a connecting plate, the lead-out path of the enameled wire can be accurately positioned, allowing the enameled wire to be directly aligned with the rotor slot after being led out from the wire wheel. This reduces offset and loss during the winding process. The design of the double upper wire wheel with staggered wire clamping ends allows for the synchronous layered supply of two strands of enameled wire, each corresponding to a different position in the rotor slot. They are wound synchronously as the rotor rotates, avoiding cross-interference of the enameled wires while reducing the number of axial movements and improving the wire density and uniformity.

[0018] 3. By setting up a connecting rod and a rotating rod, one end of the connecting rod is fixed to the output end of the second motor, and the other end is hinged to the rotating rod. When the second motor drives the connecting rod to rotate, the rotating rod can drive the front clamp to rotate 90°, so that the front clamp block can quickly nest into the front end of the rotor shaft. This connecting rod-rotor transmission structure uses the lever principle to convert the rotational motion of the motor into the angular displacement of the front clamp. It not only has high transmission efficiency, but also ensures the positional accuracy of the front clamp block when positioning through the precise design of the connecting rod length and the rotating rod angle, avoiding rotor offset caused by transmission error. At the same time, the structure has a buffering characteristic. When the clamp block contacts the rotor shaft, the impact can be reduced by the elasticity of the connecting rod, protecting the rotor shaft surface from damage. In addition, the detachable design of the connecting rod and the rotating rod makes it easy to adjust the installation angle of the front clamp according to different rotor specifications. With the sliding adjustment of the upper clamp block at the rear end, it can achieve adaptive clamping of rotors of different lengths and diameters, so that the equipment can maintain stable positioning accuracy in the production of multiple models of rotors, and provide support for the automation and flexible production of the winding process.

[0019] 4. In summary, this type of motor rotor winding equipment, through the arrangement of wire pulleys, slide rails, upper clamping blocks, front clamping blocks, connecting rods, and rotating rods, achieves double-layered wire supply through a staggered double-wheel layout, simultaneously completing multi-directional winding of the rotor wire slots, which both increases wire density and shortens winding time. The slide rails and upper clamping blocks form a rear-end elastic clamping structure, which, together with the front clamping blocks, achieves front-end sleeve positioning through a connecting rod and rotating rod mechanism, constructing stable mechanical limits from both ends of the rotor, effectively resisting rotational tension and centrifugal force during winding, ensuring that the rotor's position does not shift during high-speed rotation. The lever transmission design of the connecting rods and rotating rods not only gives the front clamping block a flexible positioning capability of 90° rotation, ensuring the uniformity and consistency of enameled wire winding, but also improves the equipment's adaptability to multiple rotor models through modular design.

[0025] The following will refer to the appendix in the embodiments of this utility model. Figures 1-4 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0026] Please see Figure 1-4In this embodiment of the present invention, a winding device for a motor rotor includes: a workbench 1, a placement rack 2 fixedly mounted on the front of the workbench 1, a fixed base 3 fixedly mounted below the placement rack 2, a mounting plate 4 fixedly mounted below the fixed base 3, a fixed plate 105 fixedly mounted on the front of the workbench 1, the placement rack 2, the fixed base 3, and the mounting plate 4 all mounted on the fixed plate 105, a clamping seat 304 rotatably connected to the front of the fixed base 3, a front clamping seat 404 rotatably connected to the front of the mounting plate 4, the front clamping seat 404 being matched with the clamping seat 304, a control box 101 fixedly mounted on the upper end of the workbench 1, a display screen 102 fixedly mounted on the front of the control box 101, a switch 103 fixedly mounted on the right side of the display screen 102, and several... A control knob 104 is installed. A connecting rod 201 is fixedly installed at the rear end of the placement rack 2. A base 202 is fixedly installed at the rear end of the connecting rod 201. The base 202 is fixedly installed on the fixed plate 105. A connecting plate 203 is fixedly installed on the front of the placement rack 2. A wire wheel plate 204 is fixedly installed on the front of the connecting plate 203. A wire wheel 205 is fixedly installed on the front of the wire wheel plate 204. A motor 301 is fixedly installed on the front of the fixed base 3. The output end of the motor 301 is fixedly connected to the clamp base 304. A slide rail 302 is fixedly installed in front of the motor 301. An upper clamping block 303 is slidably connected to the slide rail 302. The slide rail 302 is fixedly installed on the upper rear side of the clamp base 304. A motor 401 is fixedly installed on the left end of the mounting plate 4. A rotating part is installed on the right end of the mounting plate 4. Connecting rod 402 is fixedly connected to the output end of motor 401. A rotating rod 403 is fixedly connected to the other end of connecting rod 402. A front clamping seat 404 is fixedly connected to the surface of rotating rod 403. A front clamping block 405 is fixedly installed on the upper end of the front clamping seat 404. The front clamping block 405 is matched with clamping seat 304. First, the rotor core is placed into clamping seat 304. Then, the cylinder inside clamping seat 304 that matches slide rail 302 is driven to drive the upper clamping block 303 to move downwards along slide rail 302, thereby clamping the rear end of the rotor core. Then, motor 401 is driven, and the output end of motor 401 rotates, causing connecting rod 402 to rotate around the output end, thereby driving rotating rod 403 to rotate. Since rotating rod 403 is fixedly connected to front clamping seat 404, the front clamping seat 405... 04. Rotate 90 degrees backward to engage the front clamp 405 with the clamp seat 304, limiting the rotor from the front. The rear end of the front clamp 405 is a sleeve, which can nest the rotor shaft to form a "front and rear clamping" structure, ensuring that the rotor is stable and does not wobble during winding. The enameled wire is wound on the spool 205, and the spool plate 204 is fixed on the connecting plate 203, so that after the enameled wire is led out from the spool 205, it can be accurately aligned with the wire slot of the rotor core. Then, the motor 301 is started, and its output end drives the clamp seat 304 to rotate, so that the rotor core rotates synchronously. With the feeding of the enameled wire, the winding action is completed, realizing the helical arrangement of the enameled wire in the rotor slot. The winding parameters (such as number of turns, wire diameter, tension) are set through the display screen 102 on the control box 101.Control knob 104 adjusts the motor speed and winding rhythm, switch 103 starts / pauses the equipment, realizing an automated winding process. After winding is completed, upper clamp 303 is released along slide rail 302, front clamp 405 returns to its original position with front clamp seat 404, and the operator can remove the wound rotor.

[0027] In this embodiment of the utility model, there are two wire spools 205, and their wire clamping ends are respectively set one above the other. The upper and lower wire clamping ends can correspond to different positions of the rotor wire slot, reducing the number of axial movements during the winding process and increasing the wire density. After the enameled wire is led out from the upper wire spool, it is aligned with the upper side of the rotor wire slot; the enameled wire on the lower wire spool corresponds to the lower side of the wire slot. The two wires are wound synchronously with the rotor rotation to avoid cross interference.

[0028] Working principle: First, the rotor core is placed into the clamping seat 304. Then, the cylinder inside the clamping seat 304, which is adapted to the slide rail 302, is driven to move the upper clamping block 303 downward along the slide rail 302, thereby clamping the rear end of the rotor core. Then, the second motor 401 is driven, and the output end of the second motor 401 rotates, causing the connecting rod 402 to rotate around the output end, thereby driving the rotating rod 403 to rotate. Since the rotating rod 403 is fixedly connected to the front clamping seat 404, the front clamping seat 404 rotates backward by 90 degrees, so that the front clamping block 405 cooperates with the clamping seat 304 to limit the rotor from the front end. The rear end of the front clamping block 405 is set with a sleeve, which can nest the rotor shaft to form a "front and rear clamping" structure, ensuring that the rotor is stable and does not shake during the winding process. The enameled wire is wound on... On the spool 205, the spool plate 204 is fixed on the connecting plate 203, so that after the enameled wire is led out from the spool 205, it can be accurately aligned with the wire slot of the rotor core. Then the motor 301 is started, and its output end drives the clamp seat 304 to rotate, so that the rotor core rotates synchronously. In conjunction with the feeding of the enameled wire, the winding action is completed, realizing the spiral arrangement of the enameled wire in the rotor slot. The winding parameters (such as number of turns, wire diameter, tension) are set through the display screen 102 on the control box 101, the control knob 104 adjusts the motor speed and the winding rhythm, and the switch 103 starts / pauses the equipment to realize the automated winding process. After the winding is completed, the upper clamp 303 is released along the slide rail 302, and the front clamp 405 is reset with the front clamp seat 404. The operator can take out the rotor that has been wound.
