Description

Technical Field

[0001] This utility model relates to the field of rotor precision machining technology, specifically a fully automatic rotor precision turning machine. Background Technology

[0002] The fully automatic rotor precision turning machine is a key piece of equipment for precision machining of motor rotors. It integrates an automatic rotor placement mechanism, a positioning mechanism, a tool movement platform, and a double-head device, and achieves automatic feeding, turning, and inspection through servo drive. It is used for machining commutators and cores of brushed motor rotors, solving the problem of low efficiency in traditional manual operation.

[0003] A search revealed Chinese Patent Publication No. CN104289729A: A fully automatic rotor precision turning machine, comprising a feeding assembly, a tool holder assembly, a servo press assembly, a turning seat assembly, a discharging assembly, a detection assembly, and a handling robot assembly; the feeding assembly includes a fly-off mechanism, a rotor, a stop bar, and a first push bar; the tool holder assembly is equipped with a turning tool; the servo press assembly is equipped with a transmission rubber wheel; the turning seat assembly is equipped with a rotor turning seat; the discharging assembly includes a fly-off mechanism, a second push bar, a qualified product channel, and a defective product channel; the detection assembly includes a pusher mechanism, a detection seat, a lifting slide, and a lifting cylinder; the handling robot assembly includes a motor, a conveyor belt, and a robot arm.

[0004] While the aforementioned device changes the traditional belt-driven rotor rotation for turning by directly using rubber wheels, resulting in more powerful and stable transmission and improved turning precision, it doesn't adequately address the issue of insufficient transmission stability. The rubber wheels experience uneven elastic deformation after prolonged compression, causing radial displacement of the rotor. Furthermore, increased turning resistance can lead to slippage between the rubber wheels and the rotor surface, causing fluctuations in rotor speed. To address these problems, we offer a fully automatic rotor precision turning machine. Utility Model Content

[0006] This utility model proposes a fully automatic rotor precision machining machine. Through the cooperation between components such as rotor slots, hydraulic telescopic rods, and servo motors, it solves the problems of uneven elastic deformation of rubber wheels after long-term compression, which causes radial positioning deviation of the rotor, and the rubber wheels easily slipping on the rotor surface when the machining resistance increases, resulting in the rotor speed fluctuating.

[0007] (ii) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a fully automatic rotor precision turning machine, including a mounting plate, a rotor detection device mounted on the upper surface of the mounting plate, a robotic arm mounted on the upper surface of the mounting plate, a tool adjustment mechanism disposed above the mounting plate, and a rotation mechanism disposed above the mounting plate;

[0009] The rotating mechanism includes a conveying frame. A limiting groove is formed in the inner bottom wall of the conveying groove of the conveying frame. A rotor groove is formed on the lower surface of the conveying groove of the conveying frame. The rotor conveyed from the right end of the limiting groove will fall directly into the interior of the rotor groove. A first through hole is formed on the front of the conveying frame. A hydraulic telescopic rod is installed on the front of the conveying frame. The piston rod of the hydraulic telescopic rod passes through the first through hole and is rotatably connected to a second rotating disk. A second through hole is formed on the rear side of the conveying frame. A servo motor is installed on the back of the conveying frame.

[0010] Furthermore, the lower surface of the conveying frame is fixedly connected to the upper surface of the mounting plate, the rotating shaft of the servo motor passes through the second through hole, and the hydraulic telescopic rod extends by controlling the piston rod, so that the second rotating disk and the rotating shaft of the servo motor can clamp the rotor inside the rotor slot, and the central axis of the rotating shaft of the servo motor, the central axis of the second rotating disk, and the central axis of the rotor inside the rotor slot are collinear.

[0011] Furthermore, the tool adjustment mechanism includes a hydraulic lift, which is fixedly installed on the upper surface of the mounting plate, and a lifting plate is fixedly connected to the output end of the hydraulic lift.

[0012] Furthermore, two symmetrical connecting plates are fixedly connected to the lower surface of the lifting plate, and connecting blocks are slidably connected to the sides of the two connecting plates that are close to each other.

[0013] Furthermore, turning tools are installed on the lower surfaces of both connecting blocks, and the working positions of the bottom of the two turning tools and the turning positions at both ends of the rotor inside the rotor slot form a longitudinal positioning reference.

[0014] Furthermore, threaded cylinders are fixedly connected to the upper surfaces of both turning tools, and threaded cavities are opened at the top ends of both threaded cylinders. Two symmetrical rotating holes are opened on the upper surface of the lifting plate.

[0016] (iii) Beneficial effects:

[0017] Compared with existing technologies, this fully automatic rotor precision turning machine has the following advantages:

[0018] 1. This fully automatic rotor precision turning machine guides the rotor to slide through the limiting groove of the conveyor frame, and achieves preliminary precise positioning of the rotor in conjunction with the rotor groove; then, the hydraulic telescopic rod pushes the second rotating disk, which cooperates with the rotating shaft of the servo motor to clamp the rotor, and the central axes of the three are collinear to avoid radial offset of the rotor during clamping; subsequently, the servo motor drives the rotor to rotate at a uniform speed, effectively reducing the position deviation and speed fluctuation during the rotor turning process, and ensuring the turning dimensional accuracy and surface finish of the rotor commutator, iron core and other parts.

[0019] II. This fully automatic rotor precision turning machine, through the cooperation of components such as a hydraulic lift, threaded rod and connecting plate, can not only adjust the longitudinal height of the turning tool by driving the lifting plate through the hydraulic lift, but also control the threaded rod to rotate along the rotating hole and engage with the threaded cavity through the first rotating disc, pushing the connecting block to slide along the connecting plate. It can adjust the turning tool on one side to achieve single-end turning of the rotor, or adjust the turning tools on both sides simultaneously to achieve turning at both ends of the rotor, flexibly adapting to the turning end requirements of different rotors, without the need to change special tooling, thus expanding the processing application range of the equipment.

[0027] 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.

[0028] The rotor detection device 2, robotic arm 3, hydraulic lift 401, hydraulic telescopic rod 505, and servo motor 508 in this utility model are all mature electric and hydraulic equipment in the prior art. This application will not elaborate on their models or internal structures.

[0029] like Figure 1-5 As shown, this utility model provides a technical solution: a fully automatic rotor precision turning machine, including a mounting plate 1, a rotor detection device 2 mounted on the upper surface of the mounting plate 1, a robotic arm 3 mounted on the upper surface of the mounting plate 1, a tool adjustment mechanism 4 arranged above the mounting plate 1, and a rotating mechanism 5 arranged above the mounting plate 1. The rotating mechanism 5 includes a conveying frame 501, a limiting groove 502 formed in the inner bottom wall of the conveying groove of the conveying frame 501, a rotor groove 503 formed on the lower surface of the conveying groove of the conveying frame 501, the rotor conveyed from the right end of the limiting groove 502 falling directly into the rotor groove 503, a first through hole 504 formed on the front of the conveying frame 501, and a hydraulic telescopic rod 505 mounted on the front of the conveying frame 501. The piston rod of the hydraulic telescopic rod 505 passes through the first through hole 504 and is rotatably connected to the second rotating disk 506. The rear side of the conveying frame 501 is provided with a second through hole 507. A servo motor 508 is installed on the back of the conveying frame 501. The lower surface of the conveying frame 501 is fixedly connected to the upper surface of the mounting plate 1. The rotating shaft of the servo motor 508 passes through the second through hole 507. By controlling the piston rod to extend, the hydraulic telescopic rod 505 can make the second rotating disk 506 and the rotating shaft of the servo motor 508 clamp the rotor inside the rotor slot 503. The central axis of the rotating shaft of the servo motor 508, the central axis of the second rotating disk 506, and the central axis of the rotor inside the rotor slot 503 are collinear.

[0030] The rotor to be processed first slides along the limiting groove 502 through the conveying frame 501 of the rotating mechanism 5 and accurately falls into the rotor groove 503 to complete the initial positioning. Then, the piston rod of the hydraulic telescopic rod 505 extends along the first through hole 504 and pushes the second rotating disk 506 at the end to move towards the rotor. At the same time, the rotating shaft of the servo motor 508 extends along the second through hole 507. The two work together to clamp the rotor from both ends. The central axis of the second rotating disk 506, the central axis of the rotating shaft of the servo motor 508 and the central axis of the rotor are collinear, ensuring that the rotor has no radial offset. This effectively reduces the position deviation and speed fluctuation during the rotor turning process and ensures the turning dimensional accuracy and surface finish of the rotor commutator, iron core and other parts.

[0031] The tool adjustment mechanism 4 includes a hydraulic lift 401, which is fixedly installed on the upper surface of the mounting plate 1. A lifting plate 402 is fixedly connected to the output end of the hydraulic lift 401. Two symmetrical connecting plates 403 are fixedly connected to the lower surface of the lifting plate 402. Connecting blocks 404 are slidably connected to the sides of the two connecting plates 403 that are close to each other. Turning tools 405 are mounted on the lower surfaces of the two connecting blocks 404. The working positions of the bottom of the two turning tools 405 are aligned with the rotor inside the rotor slot 503. The turning positions at both ends form a longitudinal positioning reference. Threaded cylinders 406 are fixedly connected to the upper surfaces of both turning tools 405. Threaded cavities 407 are opened at the top ends of both threaded cylinders 406. Two symmetrical rotating holes 408 are opened on the upper surface of the lifting plate 402. Threaded rods 409 are rotatably connected to the inner walls of both rotating holes 408. First rotating disks 410 are fixedly connected to the top ends of both threaded rods 409. The threaded surfaces of the two threaded rods 409 are threadedly connected to the inner walls of the two threaded cavities 407 respectively.

[0032] According to the machining requirements of "turning one end" or "turning both ends" of the rotor, multi-dimensional adjustment is performed through the tool adjustment mechanism 4: First, the hydraulic lift 401 is started to drive the lifting plate 402 to move up and down, thereby adjusting the longitudinal height of the turning tool 405; then, by rotating the first rotating disk 410, the threaded rod 409 is controlled to rotate along the rotating hole 408 of the lifting plate 402, and at the same time, the threaded surface of the threaded rod 409 engages with the threaded cavity 407 of the threaded cylinder 406, pushing the connecting block 404 to slide along the connecting plate 403. If the threaded rod 409 on one side is adjusted alone, the connecting block 404 on one side can drive the corresponding turning tool 405 to move to the single end of the rotor for turning. Position; if the threaded rods 409 on both sides are adjusted simultaneously, the turning tools 405 on both sides will move synchronously to the turning positions at both ends of the rotor; finally, the working position of the turning tool 405 and the target turning position of the rotor form a longitudinal positioning reference; then the servo motor 508 starts to drive the rotor to rotate at a uniform speed, while controlling the hydraulic lifting platform 401 to descend uniformly, driving the lifting plate 402, connecting plate 403 and connecting block 404 to move down synchronously, so that the turning tool 405 smoothly approaches and contacts the rotor surface, and performs precision turning operations on the commutator, iron core and other parts, flexibly adapting to the turning end requirements of different rotors, without the need to change special tooling, thus expanding the processing application range of the equipment.

[0033] Working Principle: When this fully automatic rotor precision turning machine is working, the rotor to be processed first slides along the limiting groove 502 through the conveying frame 501 of the rotating mechanism 5, and accurately falls into the rotor groove 503 to complete the initial positioning; then, the piston rod of the hydraulic telescopic rod 505 extends along the first through hole 504, pushing the second rotating disk 506 at the end to move towards the rotor, and at the same time, the rotating shaft of the servo motor 508 extends along the second through hole 507. The two work together to clamp from both ends of the rotor, and the central axis of the second rotating disk 506, the central axis of the rotating shaft of the servo motor 508 and the central axis of the rotor are collinear to ensure that the rotor has no radial offset; then, according to the processing requirements of "turning one end" or "turning both ends" of the rotor, multi-dimensional adjustment is performed through the tool adjustment mechanism 4: first, the hydraulic lifting platform 401 is started to drive the lifting plate 402 to move up and down to realize the longitudinal height adjustment of the turning tool 405; then, by rotating the first rotating disk 410, the threaded rod 409 is controlled to rotate along the rotating hole 408 of the lifting plate 402, and at the same time, the threaded surface of the threaded rod 409 and the threaded cylinder 409 are aligned. The threaded cavity 407 of 06 engages, pushing the connecting block 404 to slide along the connecting plate 403. If one side of the threaded rod 409 is adjusted individually, the connecting block 404 on one side can move the corresponding turning tool 405 to the turning position at one end of the rotor. If both sides of the threaded rod 409 are adjusted simultaneously, the turning tools 405 on both sides move synchronously to the turning positions at both ends of the rotor. Finally, the working position of the turning tool 405 and the target turning position of the rotor form a longitudinal positioning reference. Then, the servo motor 508 starts and drives the rotor to rotate at a uniform speed. At the same time, the hydraulic lifting platform 401 is controlled to descend uniformly, driving the lifting plate 402, connecting plate 403 and connecting block 404 to move down synchronously, so that the turning tool 405 smoothly approaches and contacts the rotor surface to perform precision turning operations on the commutator, iron core and other parts. After the turning is completed, the hydraulic telescopic rod 505 resets and releases the rotor. The robot 3 transports the rotor to the rotor detection device 2 to detect the rotor accuracy. Qualified products are transported to the next process by the robot 3, and defective products are rejected according to the preset path, realizing fully automated operation.
