Description

Technical Field

[0001] This invention relates to the field of commutator technology, and in particular to an automatic milling and turning machine for slotted commutators. Background Technology

[0002] Slotted commutators are core components of rotating electrical equipment such as motors and generators. They mainly consist of copper commutator segments, insulating materials, and bushings. Their surface has evenly distributed slots for embedding winding coils and achieving current commutation. Their core function is to convert external DC power into alternating current required by the rotor windings, or conversely, to convert the alternating current generated by the rotor into usable external DC current, ensuring continuous and stable motor operation. Slotted commutators are widely used in automobiles, home appliances, and industrial motors, and their machining precision directly affects the motor's operating efficiency, service life, and stability.

[0003] In industrial production, the machining of slotted commutators involves two key processes: milling and turning the outer diameter. These two processes directly determine the core precision and performance of the product. However, traditional machining methods have long relied on independent operation of horizontal milling machines and horizontal lathes, which presents numerous problems. During production, workpieces must be manually transferred from the milling machine to the lathe, creating multiple production interruptions. This not only leads to poor production continuity and low connection efficiency but also increases the risk of workpiece collisions and positioning deviations due to human error, causing batch quality issues. The dimensional adjustment process requires manual adjustment of mechanical devices, which is cumbersome and time-consuming, resulting in high labor intensity and difficulty in ensuring dimensional consistency across batches. Furthermore, in single-machine operation mode, equipment changeover and debugging are complex, and the machine is poorly adaptable to the needs of multi-specification, small-batch production, failing to meet the requirements of efficient, precise, and flexible production in modern industry, severely restricting the improvement of production efficiency and product competitiveness. Therefore, those skilled in the art provide an automated milling and turning machine for slotted commutators to solve the problems mentioned in the background. Summary of the Invention

[0022] Example 1

[0023] Please see Figure 1-7 As shown, this embodiment is an automatic machining machine for slotted commutators that integrates turning and milling. It includes a base 1, a feeding platform 2, a first feeding module 3, a second feeding module 4, a lathe 7, and a milling machine 13. The lathe 7 and the milling machine 13 are distributed on both sides of the upper end of the base 1. A lathe spindle chuck 6 is located on the front side of the lathe 7 at the upper end of the base 1. A milling mandrel chuck 5 is located on the front side of the milling machine 13. The feeding platform 2 is located on the front side of the upper end of the base 1. The first feeding module 3 and the second feeding module 4 are located on the upper end of the feeding platform 2. A second tailstock 10 and a first tailstock 11 are fixed on the upper part of the base between the lathe 7 and the milling machine 13. The lathe equipment 7 includes a lathe Y-axis module 8 and a lathe X-axis module 9, with a lathe tool spindle 25 provided at one end of the X-axis module; The milling equipment 13 includes a milling motor 12, a milling Y-axis module 14 and a milling X-axis module 15, and a milling cutter shaft 16 is provided at the front end of the milling Y-axis module 14. The front end of the equipment base 1 has a control panel assembly slot 27, and the equipment base 1 has a hollow frame structure. The first feeding module 3 includes a first gripper Y-axis module 19 fixed on the upper end of the feeding platform 2, a first gripper rotating shaft module 20 is provided at the rear end of the first gripper Y-axis module 19, and a first gripper 21 driven by a cylinder is provided at the rear end of the gripper rotating shaft module. The second feeding module 4 includes a second gripper Y-axis module 22 fixed on the upper end of the feeding platform 2, and a second gripper 23 is provided at the rear end of the second gripper Y-axis module 22. Symmetrically distributed support seats 17 are provided on the front side of the upper end of the base. Guide rails 18 are provided between the support seats 17. A slide seat 24 connected to the feeding table is slidably installed on the outer wall of the guide rail 18. A traveling cylinder 26 with its telescopic end connected to the slide seat 24 is provided on the front side of the upper end of the base. Based on the implementation steps of Embodiment 1: A hollow frame structure is adopted, which not only ensures the overall support strength of the equipment, but also effectively reduces its weight and material costs. A control panel assembly slot 27 is opened inside the front end for installing the operation control panel, which allows workers to set processing parameters such as milling groove depth, turning outer diameter, and feeding speed. Symmetrically distributed support seats 17 are fixed on the front side of the upper end of the base. Guide rails 18 are installed between the support seats 17. Slide seats 24 are slidably installed on the outer wall of the guide rails 18. The slide seats 24 are fixedly connected to the feeding platform 2, and the extension end of the traveling cylinder 26 on the base is connected to the slide seat 24. The connecting seat 24 is the core of the feeding platform 2 to achieve horizontal movement. When the traveling cylinder 26 extends and retracts, it will drive the sliding seat 24 to slide smoothly along the guide rail 18, thereby driving the feeding platform 2 and the two feeding modules above to achieve "left and right translation". This provides power for the transfer of workpieces between the milling equipment 13 and the lathe equipment 7. As the mounting carrier of the two feeding modules, the whole moves synchronously with the sliding seat 24. Its core function is to support the feeding modules to complete the entire process of "grabbing-transferring-positioning" of workpieces. It is the key to connecting the loading area, the milling processing area and the turning processing area. Feeding module 3: Composed of gripper Y-axis module 19, gripper rotary axis module 20, and gripper 21 driven by cylinders. Gripper Y-axis module 19 is responsible for driving the entire gripping assembly to achieve "vertical movement", which can accurately adjust the height of the gripper to adapt to the height difference between the workpiece loading position and the processing area. Gripper rotary axis module 20 can drive gripper 21 to achieve 360° rotation, which facilitates adjustment of the workpiece clamping angle and ensures that the workpiece is accurately aligned with the positioning requirements of milling mandrel chuck 5. Gripper 21 is driven by cylinders, and the clamping force is stable and controllable, avoiding workpiece slippage due to excessive looseness or damage due to excessive tightness. The second feeding module 4 consists of the second gripper Y-axis module 22 and the second gripper 23 driven by cylinders. Its structure is relatively simple. Its core functions are "relay clamping" and "auxiliary transfer". It achieves vertical movement through the second gripper Y-axis module 22, and works with the first feeding module 3 to complete the alternating processing of two workpieces, avoiding the processing gap caused by single module operation and improving production continuity. Lathe equipment 7 includes a lathe Y-axis module 8, a lathe X-axis module 9, and a lathe cutter spindle 25. Its core function is to complete the "outer diameter machining" of the commutator. The lathe X-axis module 9 is responsible for driving the lathe cutter spindle 25 to achieve "forward and backward lateral movement" and controlling the distance between the cutter spindle and the workpiece, i.e., the turning feed rate. The lathe Y-axis module 8 is responsible for driving the lathe cutter spindle 25 to achieve "up and down longitudinal movement". In conjunction with the rotation of the lathe spindle chuck 6, it completes the precise turning of the workpiece's outer diameter. The lathe spindle chuck 6 is located in front of the lathe equipment 7 and is used to clamp the workpiece and drive it to rotate at high speed, providing power for the turning process. Milling equipment 13 includes a milling motor 12, a milling Y-axis module 14, a milling X-axis module 15, and a milling cutter shaft 16. Its core function is to complete the "milling" of the commutator. The milling motor 12 provides high-speed rotational power to the milling cutter shaft 16 for cutting the groove. The milling X-axis module 15 drives the milling cutter shaft 16 to achieve "forward and backward lateral movement" and control the depth of the cutter shaft into the workpiece (i.e., groove depth). The milling Y-axis module 14 drives the milling cutter shaft 16 to achieve "up and down longitudinal reciprocating motion". Each up and down movement completes the cutting of one groove. The milling mandrel chuck 5 is located in front of the milling equipment 13 and is used to clamp the workpiece and accurately rotate and position it to ensure that multiple grooves are evenly distributed along the circumference of the workpiece. Tail tip 11 and tail tip 10 are fixed above the equipment base 1 and between the lathe equipment 7 and the milling equipment 13. Their core function is to "assist in clamping and positioning". When the feeding module transfers the workpiece to the milling or turning position, the tail tip will extend forward and cooperate with the corresponding chuck (milling spindle chuck 5 or lathe spindle chuck 6) to clamp and fix the workpiece from both ends, so as to prevent the workpiece from shaking or shifting during high-speed rotation processing (milling, turning) and ensure the accuracy of the processing dimensions. The core operating logic of the equipment is "full-process automated collaboration of 'feeding-positioning-processing-transfer-reprocessing'", and the coordination relationship of each structure is as follows: Feeding power transmission: The travel cylinder 26 extends and retracts → drives the slide 24 to slide along the guide rail 18 → the feeding platform 2 moves horizontally with the slide 24 → drives the first feeding module 3 / second feeding module 4 to switch positions between the "feeding area - milling area - lathe area"; Workpiece clamping and angle adjustment: No. 1 clamping jaw 21 clamps the workpiece → No. 1 clamping jaw Y-axis module 19 moves the workpiece up and down → No. 1 clamping jaw rotating axis module 20 adjusts the workpiece angle → ensures that the workpiece is precisely aligned with the chuck positioning hole. Processing positioning and fixing: The feeding platform 2 moves to the processing area → the tail tip extends and cooperates with the chuck → the workpiece is clamped from both ends → to avoid shaking during processing; Milling groove machining coordination: Milling groove motor 12 starts → Milling groove cutter shaft 16 rotates at high speed → Milling groove X-axis module 15 pushes the cutter shaft to cut into the workpiece → Milling groove Y-axis module 14 drives the cutter shaft to move up and down reciprocating → Complete the cutting of one groove → Milling groove mandrel chuck 5 rotates at an angle → Repeat the milling groove action until all grooves are machined. Collaborative turning process: Lathe spindle chuck 6 drives the workpiece to rotate at high speed → Lathe X-axis module 9 pushes the tool axis closer to the workpiece → Lathe Y-axis module 8 drives the tool axis to move up and down → Completes the turning of the workpiece's outer diameter; Dual-module alternating collaboration: When the first feeding module 3 transfers the first workpiece to the milling area for processing, the second feeding module 4 simultaneously grabs the second workpiece and waits for it; after the first workpiece is milled, the first feeding module 3 transfers it to the lathe area, and the second feeding module 4 immediately sends the second workpiece to the milling area, realizing parallel operation of "milling-turning" without processing interruption. For the machining of slotted commutators, which require the machining of multiple evenly distributed slots, traditional machining involves using a horizontal milling machine to machine the slots, followed by manual transfer to a horizontal lathe to turn the outer diameter. This process requires two workers, takes four minutes to process a single workpiece, and is prone to damage and dimensional deviations due to manual handling. This equipment completely solves these problems through integrated automated operation. The specific implementation steps are as follows: Preliminary preparation stage: The worker inputs the processing parameters, lathe spindle speed and milling motor 12 speed through the control panel at the front of the equipment base 1; the commutator blank to be processed is neatly arranged in the loading area, close to the initial position of the feeding platform 2, ensuring that the axis of the blank is aligned with the clamping center of the first clamping jaw 21. The control panel starts the equipment, the traveling cylinder 26 is in the retracted state, the feeding platform 2 is located directly in front of the loading area, the first clamping jaw Y-axis module 19 of the first feeding module 3 moves downward, driving the first clamping jaw 21 to approach the blank in the loading area, the cylinder drives the clamping jaw to close, and firmly clamps the first blank. The clamping position is the middle of the workpiece to avoid damage to the positioning surfaces at both ends. The first clamping jaw Y-axis module 19 moves upward to lift the workpiece away from the loading area to avoid collision with other blanks during transfer. At the same time, the first clamping jaw rotating shaft module 20 rotates to adjust the angle of the workpiece so that the positioning holes at both ends of the workpiece are precisely aligned with the positioning pins of the subsequent milling mandrel chuck 5. The traveling cylinder 26 slowly extends, driving the slide block 24 to slide to the left along the guide rail 18. The feeding platform 2 moves to the left in sync until the workpiece held by the first feeding module 3 is aligned with the milling mandrel chuck 5 of the milling equipment 13. The traveling cylinder 26 stops moving, and the feeding platform 2 is fixed in position. At this time, the second tail tip 10 extends forward, and its front pin is precisely inserted into the positioning hole at one end of the workpiece. At the same time, the milling mandrel chuck 5 moves forward and clamps the other end of the workpiece, forming "positioning and clamping at both ends" to ensure that the workpiece does not shake during the milling process. The milling motor 12 starts, driving the milling cutter shaft 16 to rotate at high speed. The milling X-axis module 15 advances forward, driving the milling cutter shaft 16 closer to the workpiece until the cutter shaft cuts into the workpiece surface to the set groove depth. The X-axis module stops advancing, and the milling Y-axis module 14 starts, driving the milling cutter shaft 16 to move upward at a constant speed. During the rotation of the cutter shaft, a groove is cut along the workpiece axis. When the Y-axis module moves to the set height, it returns to its original position downward. The milling mandrel chuck 5 rotates. Because multiple uniform grooves need to be processed, the rotation angle is constant each time to complete one positioning. The above "X-axis advance - Y-axis up and down cutting - chuck rotation" action is repeated to continuously process the groove. The milling cutter shaft 16 is driven by the X-axis module to return to its original position backward, and the milling motor 12 stops running. The second tail tip 10 retracts, the milling mandrel chuck 5 releases the workpiece, the first clamping jaw 21 closes again to clamp the milled workpiece, the first clamping jaw Y-axis module 19 moves upward, leaving the clamping range of the milling mandrel chuck 5, the traveling cylinder 26 continues to extend, driving the feeding platform 2 to move further to the left until the workpiece is directly facing the lathe spindle chuck 6 of the lathe equipment 7, the first tail tip 11 extends forward, the ejector pin inserts into the positioning hole at one end of the workpiece, the lathe spindle chuck 6 clamps the other end of the workpiece, forming "two-end positioning and clamping" again, the first clamping jaw 21 releases, the first clamping jaw Y-axis module 19 moves downward to reset, preparing for subsequent workpiece gripping. The lathe spindle chuck 6 starts, driving the workpiece to rotate at high speed. The lathe X-axis module 9 moves forward, driving the lathe cutter spindle 25 close to the outer diameter of the workpiece until the cutter spindle contacts the workpiece surface. The lathe Y-axis module 8 drives the cutter spindle to move upward at a constant speed. The cutter spindle cuts the outer diameter during the workpiece rotation, gradually machining the outer diameter of the workpiece to the set value. After the turning is completed, the lathe Y-axis module 8 resets, the lathe X-axis module 9 drives the cutter spindle to move backward, the lathe spindle chuck 6 stops rotating, the first tailstock 11 retracts backward, and the lathe spindle chuck 6 releases the workpiece, completing all milling and turning machining of the first workpiece. While the first workpiece is being milled, the second feeding module 4 is simultaneously activated to grip and prepare the second workpiece. The specific coordination process is as follows: When the first feeding module 3 is clamping the first workpiece in the milling area, although the traveling cylinder 26 is in the extended state, the second feeding module 4 on the feeding platform 2 is still above the loading area. The second gripper Y-axis module 22 of the second feeding module 4 moves downward, and the second gripper 23 clamps the second blank. Then the Y-axis module moves upward to reset. When the first workpiece finishes milling and the feeding platform 2 moves towards the lathe area, the second feeding module 4 moves synchronously with the platform. After the first workpiece enters the lathe area and is positioned, the second feeding module 4 moves exactly to the front of the milling area. Repeat the milling process of the first workpiece: No. 2 tail tip 10 extends + milling mandrel chuck 5 clamps → milling motor 12 starts → milling X-axis module 15 / milling Y-axis module 14 cut together → multiple grooves are processed. At this moment, the turning of the first workpiece is completed. The first feeding module 3 releases the first workpiece, and the finished product is unloaded. It can be automatically exported by the subsequent conveyor belt and immediately moved to the milling area. The second workpiece, which has been milled, is clamped and transferred to the lathe area for turning. At the same time, the feeding platform 2 returns to the unloading area, and the second feeding module 4 grabs the third blank again, entering the next round of "milling-turning" cycle. The equipment continues to operate in the above alternating mode of "module 1 processes the first workpiece → module 2 processes the second workpiece → module 1 processes the third workpiece → module 2 processes the fourth workpiece". After the finished workpiece is unloaded from the lathe area, it is automatically collected through the unloading channel reserved by the equipment. The workers only need to replenish the blanks and clean the finished products from time to time, without having to participate in the entire processing connection. From workpiece gripping, transfer, and positioning to processing and unloading, the entire process requires no manual intervention. Only one worker is needed to handle material replenishment and equipment monitoring, completely solving the high-intensity labor problem of traditional processing that requires two workers to continuously transfer materials. Processing is uninterrupted, doubling efficiency. Dual feeding modules operate alternately, allowing milling and turning to be performed in parallel, reducing processing time per workpiece and improving production efficiency. The tailstock and chuck "two-end clamping" + multi-axis module precise adjustment avoids workpiece bumps and positioning deviations caused by manual transfer, resulting in high dimensional consistency in batch processing. This completely solves the problem of "prone to batch quality issues" in traditional single-machine processing. Processing parameters can be set directly through the control panel without manual adjustment of mechanical devices, shortening changeover time and significantly reducing labor and time costs. The equipment base 1 adopts a hollow frame structure, providing high support strength and light weight. The modular design of each module facilitates individual inspection and replacement, reducing later maintenance costs. This technology solves the problems of "numerous production breakpoints and low connection efficiency" caused by the traditional "horizontal lathe + horizontal milling machine" single-machine separate processing, realizing "integrated turning and milling" continuous production; it also solves the problems of "high labor load and long time consumption" caused by "manual workpiece transfer and manual size adjustment" in traditional processing, significantly reducing reliance on manual labor; it solves the problem of "frequent batch quality problems" caused by "inaccurate positioning and excessive manual intervention" in traditional single-machine processing, improving product dimensional consistency and pass rate; and it solves the problem of "uneconomical small-batch production" caused by "complex equipment changeover and debugging" in traditional equipment, enabling parametric adjustment to adapt to the processing of multiple specifications of commutators, enhancing equipment flexibility. The core competitiveness of this slotted commutator milling and turning integrated automatic machining machine lies in its "structural synergy and automated integration." It constructs a feeding power system through the traveling cylinder 26, guide rail 18, and slide 24; achieves alternating operation through dual feeding modules; and ensures machining accuracy through the multi-axis module in conjunction with the chuck and tailstock. Ultimately, it upgrades the traditional "dispersed, manual-dependent, and inefficient" machining mode to an "integrated, automated, highly efficient, and precise" production mode. This not only significantly improves production efficiency and product quality but also reduces labor and changeover costs, fully meeting the modern industrial demand for "batch, high precision, and low cost" machining of commutators. Working steps: The product is delivered to the loading position → Clamping jaw 21 (number 1) clamps the reversing mechanism → Clamping jaw 21 moves upward → Feeding moves to the left → Tail top 11 clamps → Clamping jaw 21 opens → Milling mandrel chuck 5 rotates and positions → Milling X-axis module 15 moves forward → Milling motor 12 starts rotating → Milling Y-axis module 14 moves up and down once to mill one groove, continuously processing to complete product milling → Feeding moves to the right → Clamping jaw 21 descends → Clamping jaw 21 clamps the product → Clamping jaw 21 moves upward → Clamping jaw 23 descends, ... Clamping jaw 23 clamps the material → Clamping jaw 23 moves upward → Feeding moves to the left → Tail top 11 presses down → Clamping jaw 21 opens → Milling spindle chuck 5 rotates and positions → Milling X-axis module 15 moves forward → Milling motor 12 starts rotating → Milling Y-axis module 14 moves up and down once to mill one groove, continuously processing the product to complete milling → Clamping jaw 23 opens → Lathe X-axis module 9 moves forward → Lathe spindle chuck 6 rotates → Lathe Y-axis module 8 moves forward. After processing is completed, it is pushed back to the original position → Lathe X-axis module 9 is pushed backward → Feeding moves to the right → Product processing is completed; Once the equipment is put into normal production, it enables one-piece automated production, improving the stability of the production line, eliminating sudden batch problems that may occur during single-machine automated production, and allowing the equipment to process two products continuously, thereby improving production efficiency, reducing the time for equipment changeover and dimensional adjustment, reducing the labor intensity of manual workers, meeting customers' stricter product quality and delivery requirements, and increasing the company's competitiveness.
