Description

Technical Field

[0001] The present application relates to the field of commutator processing equipment, and in particular to a DC motor commutator notch finishing device. Background Art

[0002] The rotor in a DC motor mainly includes an armature core, an armature winding, a commutator and a rotating shaft, wherein the surface of the commutator is usually provided with a notch. In order to improve the accuracy of the notch, the commutator notch needs to be fine-turned, that is, the commutator notch needs to be fine-machined.

[0003] After finishing, the notch needs to be cleaned manually with a brush. After cleaning, the entire finishing process of the commutator notch is completed. Due to the manual cleaning method of the notch, some debris is likely to remain in the notch, and workers usually use random inspections to inspect the commutator after finishing. At this time, some commutators with debris are not easily detected, thus affecting the overall quality of the motor. Products with defects need to be re-finished and cleaned, which prolongs the overall finishing cycle of the commutator, resulting in low working efficiency of the finishing device. Summary of the invention

[0004] In order to improve the problem that the debris removal effect of the commutator is poor after fine turning and rework is required, the present application provides a DC motor commutator notch fine turning device.

[0005] The present application provides a DC motor commutator notch finishing device, which adopts the following technical solution:

[0006] A DC motor commutator notch finishing device comprises a machine platform, wherein the machine platform is provided with a turning station, a cleaning station and an inspection station; the turning station comprises a tool holder driven by an electric slide, and the tool holder is provided with a tool for cutting the commutator; the cleaning station comprises a roller brush driven by a first motor, and the roller brush is used to brush the commutator; the inspection station comprises a visual inspection mechanism, and the visual inspection mechanism is used to take pictures of the commutator and analyze it.

[0007] By adopting the above technical solution, after the tool has completed turning the commutator, the commutator will move to the cleaning station. The roller brush on the cleaning station will scrape the commutator, thereby effectively removing the waste chips generated during the turning process. The commutator will then be inspected by the visual inspection mechanism of the inspection station, which can effectively improve the finishing efficiency of the commutator and avoid rework.

[0008] Optionally, a material transfer mechanism and several material parking mechanisms are provided on the machine platform, and a material parking mechanism is correspondingly provided on the outer side of the turning station and the outer side of the cleaning station, and the material transfer mechanism passes through the inner side of the material parking mechanism; the material parking mechanism includes a pair of support seats arranged at intervals along the axial direction of the commutator, and a pair of supporting wheels that can rotate around themselves are provided on the top of the support seats, and the pair of supporting wheels are arranged at intervals along the same plane, and the distance between the pair of supporting wheels is smaller than the outer diameter of the shaft body of the commutator, and the shaft body of the commutator is mounted between the pair of supporting wheels; the material transfer mechanism includes a long strip-shaped base, which is passed through a pair of support seats, a slide rail is provided on the base, and several supporting seats are provided on the top of the slide rail, and the supporting seats are arranged corresponding to the material parking mechanism, and a horizontal cylinder for pushing the slide rail to move along the length direction of the base is provided on the base, and a vertical cylinder for pushing the base to move along the height direction of the supporting seat is provided on the machine platform.

[0009] By adopting the above technical solution, when the commutator is turned at the turning station, the material transfer mechanism is activated to transfer the commutator from the support seat at the rear side of the turning station to the support seat at the cleaning station, further improving the turning efficiency of the commutator.

[0010] Optionally, a conveyor belt is provided between the cleaning station and the inspection station, and a plurality of supporting seats are also provided on the conveyor belt. The front end of the conveyor belt is close to the cleaning station, and the visual inspection mechanism is arranged above the rear end of the conveyor belt.

[0011] By adopting the above technical solution, the cleaned commutator is transported to the inspection station via the conveyor belt, and the supporting seats on the conveyor belt are arranged more densely, so more commutators can be stored, thereby avoiding the disordered stacking of commutators caused by inconsistent processing efficiency between the cleaning station and the inspection station.

[0012] Optionally, a mechanical gripper is provided at the front side of the turning station and between the cleaning station and the conveyor belt, and the mechanical gripper is used to grab the commutator and place it on the material parking mechanism or the conveyor belt.

[0013] By adopting the above technical solution, the mechanical gripper can accurately and quickly grasp the commutator and place it on the supporting seat of the material parking mechanism or the supporting seat of the conveyor belt.

[0014] Optionally, a lifting platform is provided on the machine, a mounting plate is provided on the lifting platform, two roller groups are provided on the mounting plate, one roller group is located above the turning station, and the other roller group is located above the cleaning station; the roller group includes a plurality of rollers, and a second motor is also provided on the lifting platform, the second motor is used to drive any roller to rotate around itself, a driving belt is provided on the outer side of the plurality of rollers, the driving belt is polygonal under the tensioning action of the plurality of rollers, and the driving belt is used to fit the top of the commutator and drive the commutator to rotate on the material parking mechanism.

[0015] By adopting the above technical solution, the lifting platform is lifted and lowered along the height direction of the machine platform, so as to realize the driving effect on the two roller groups and make the driving belt contact with the top of the commutator. When the second motor starts to drive the roller, the driving belt stretched by the rollers will be in a rolling state, and the rolling of the driving belt will drive the commutator to rotate, thereby improving the brushing effect of the roller brush on the commutator.

[0016] Optionally, a dust suction mechanism is provided on the turning station, and the dust suction mechanism includes a fixed shell and a movable shell, the fixed shell is fixedly arranged on the machine platform, and the movable shell is fixedly arranged on the lifting platform, the opening of the fixed shell faces the movable shell, and the opening of the movable shell faces the fixed shell, and the fixed shell and the movable shell together form a dust suction hood; the shaft of the commutator located on the material parking mechanism penetrates into the inner side of the fixed shell, and a notch is provided on the side of the movable shell facing the tool, and the tool moves to the inner side of the dust suction hood through the notch and turns the end of the commutator, and a dust suction pipe is provided at the bottom of the fixed shell, and the dust suction pipe is used to absorb waste chips in the dust suction hood.

[0017] By adopting the above technical solution, when the lifting platform drives the driving belt to move downward and makes the commutator rotate on the support seat, the fixed shell and the movable shell are also in a docking state, so that the position of the commutator to be turned is located on the inner side of the dust cover, and then the tool enters the inner side of the dust cover through the gap under the drive of the electric slide and turns the commutator. In the process of turning the commutator by the tool, a large amount of waste chips will be generated, most of which will be sucked away by the dust pipe to prevent the waste chips from flying around, and a small amount of waste chips will adhere to the surface of the commutator.

[0018] Optionally, the movable housing and the first motor are connected to a mounting plate via a bracket, the roller brush is disc-shaped and sleeved on an output shaft of the first motor, and the axis of the roller brush is perpendicular to the axis of the commutator.

[0019] By adopting the above technical solution, when the roller brush rolls and cleans the commutator under the drive of the first motor, the swept waste chips will fly away along the axial direction of the commutator, thus avoiding the waste chips from adhering to other commutators again to the greatest extent.

[0020] Optionally, a dust sweeping mechanism for sweeping away waste debris on the surface of the driving belt is provided on the outer side of the driving belt located at the rear side of the cleaning station; the dust sweeping mechanism includes an upper clamping plate and a lower clamping plate arranged on the mounting plate, and the driving belt passes through the upper clamping plate and the lower clamping plate, and suction ports are provided on both sides of the bottom of the upper clamping plate, and a plurality of blowing ports are provided on the top of the lower clamping plate, and the blowing ports are used to blow air toward the driving belt, and the suction ports are used to suck the gas blown out of the blowing ports.

[0021] By adopting the above technical solution, when the driving belt rotates to the top of the commutator, the bottom of the driving belt will rub the commutator, and at this time, more waste chips will adhere to the bottom of the driving belt. When this part turns away from the commutator, it will pass between the upper clamping plate and the lower clamping plate. At this time, the upper clamping plate and the lower clamping plate will form an air curtain. In the process of the driving belt turning into and away from the air curtain, the waste chips adhered to the air surface will be reliably removed and sucked into the air intake port, which effectively improves the surface cleanliness of the driving belt and prevents the waste chips on the driving belt from causing secondary pollution to the commutator.

[0022] Optionally, a waist hole is provided on the mounting plate, and a bolt for locking the upper splint and the lower splint is passed through the waist hole. The top of the upper splint is provided with an exhaust pipe connected to the air suction port, and the bottom of the lower splint is provided with an air inlet pipe connected to the air blowing port.

[0023] By adopting the above technical solution, the bolt can slide in the waist hole to adjust the installation position of the upper clamping plate and the lower clamping plate, so that the air curtain formed between the upper clamping plate and the lower clamping plate can more reliably blow away and absorb the waste chips adhering to the surface of the drive belt. The air inlet pipe is used to transport gas into the lower clamping plate so that air can be blown out at the air outlet, and the air exhaust pipe is used to form negative pressure at the air inlet, so as to reliably absorb the waste chips.

[0024] Optionally, the dust sweeping mechanism also includes an L-shaped vertical plate, the horizontal end of the vertical plate is connected to the mounting plate, and the vertical end of the vertical plate is located on the outside of the upper clamping plate and the lower clamping plate; a rotating tube driven by a third motor is provided on the vertical plate, one end of the rotating tube is passed through the vertical end of the vertical plate, one end of the rotating tube is connected to an air suction pipe through a rotating joint, and the other end of the rotating tube is provided with bristles and air suction holes, the bristles and the air suction holes are spaced apart and arranged in a ring on the outer wall of the rotating tube, and the bristles are used to brush the drive belt.

[0025] By adopting the above technical solution, the third motor is activated to drive the rotating tube to rotate, so that the bristles can brush the surface of the driving belt, and the suction hole can timely suck out the waste scraps swept by the brush and discharge them through the suction pipe. The setting of the rotary joint can prevent the suction pipe from being entangled without affecting the flow of air, thereby ensuring that the waste scraps brushed out by the bristles can be quickly sucked out.

[0026] In summary, this application has the following beneficial effects:

[0027] 1. The commutator passes through the turning station, cleaning station and inspection station in turn, ensuring that after the commutator is turned, it can be reliably brushed by the roller brush in the cleaning station to remove the waste chips generated during the turning process, and then photographed and analyzed by the visual inspection mechanism of the inspection station, so as to reliably detect the cleaning results of the commutator, effectively improving the precision turning efficiency of the commutator and reducing the rework ratio.

[0028] 2. The drive belt used to drive the commutator to rotate is blown and scraped by the dust sweeping mechanism, which can effectively remove the waste debris adhering to the surface of the drive belt, thereby preventing the waste debris from causing secondary pollution to the commutator or affecting the scraping effect of the roller brush on the waste debris on the commutator.

[0049] The following is combined with Figure 1-9 This application is described in further detail.

[0050] Figure 1 is a schematic three-dimensional diagram of the present application. Figure 1 A DC motor commutator slot finishing device includes a machine platform 1, on which a turning station 2, a cleaning station 3 and a testing station 4 are sequentially arranged. A material parking mechanism 7 is arranged at the rear side of the turning station 2, the rear side of the cleaning station 3 and the front side of the testing station 4, a conveyor belt 8 is arranged between the cleaning station 3 and the testing station 4, a material transfer mechanism 6 is arranged on the machine platform 1, and the material transfer mechanism 6 passes through the material parking mechanism 7, and a mechanical gripper 9 is arranged at the front end of the turning station 2, that is, between the cleaning station 3 and the conveyor belt 8.

[0051] See also Figure 1The mechanical gripper 9 first grabs the commutator 5 and places it on the material parking mechanism 7 on the rear side of the turning station 2, and then performs the fine turning operation. After the fine turning is completed, the material transfer mechanism 6 grabs the commutator 5 and places it on the material parking mechanism 7 on the rear side of the cleaning station 3. After the cleaning is completed, the material transfer mechanism 6 grabs the commutator 5 and places it on the material parking mechanism 7 on the front side of the detection station 4. Then the mechanical gripper 9 grabs the commutator 5 and places it on the conveyor belt 8 for detection.

[0052] Figure 2 This is a reference diagram of the assembly status of the material parking mechanism and the material transfer mechanism. Figure 2 The material parking mechanism 7 includes a pair of support seats 71 arranged at intervals along the axial direction of the commutator 5. The top of each support seat 71 is provided with two supporting wheels 72 that can rotate around itself. The two supporting wheels 72 are arranged at intervals along the same plane, that is, the two supporting wheels 72 are arranged side by side, and the distance between the two supporting wheels 72 is smaller than the outer diameter of the shaft body of the commutator 5. In this way, the commutator 5 can be mounted between the pair of support seats 71, and one end of the shaft body of the commutator 5 is placed between the pair of supporting wheels 72 of one support seat 71, and the other end of the shaft body of the commutator 5 is placed between the pair of supporting wheels 72 of the other support seat 71.

[0053] See also Figure 1 and Figure 2 The material transfer mechanism 6 includes a long strip base 61, which is inserted between a pair of support seats 71, that is, the base 61 is located below the commutator 5. A slide rail 62 and a horizontal cylinder 64 are provided on the top of the base 61. The horizontal cylinder 64 is used to drive the slide rail 62 to slide along the length direction of the base 61 on the top of the base 61. A vertical cylinder 65 is provided on the machine 1. The vertical cylinder 65 is used to drive the base 61 and the slide rail 62 to move in the vertical direction as a whole. A supporting seat 63 is provided on the top of the slide rail 62. The number of the supporting seats 63 is consistent with the number of the material parking mechanism 7, and the distance between two adjacent supporting seats 63 is consistent with the distance between two adjacent material parking mechanisms 7. When the commutator 5 is being turned or cleaned, the supporting seat 63 is located below the commutator 5. When the commutator 5 on the pair of supporting seats 71 needs to be moved, the vertical cylinder 65 is actuated to drive the supporting seat 63 to move upward, thereby lifting the commutator 5. Then the horizontal cylinder 64 is actuated to push the slide rail 62 to slide, thereby moving the commutator 5 to above the supporting seat 71 of the next station. Then the vertical cylinder 65 retracts, so that the commutator 5 can fall onto the pair of supporting seats 71 of the next station, thereby realizing the transfer of the commutator 5 from the turning station 2 to the cleaning station 3, with a high degree of automation and high transfer efficiency.

[0054] See also Figure 2, a lifting platform 10 is provided on the machine 1, and the lifting platform 10 is lifted and lowered in the vertical direction. A mounting plate 101 is provided on the lifting platform 10, and the mounting plate 101 is vertically arranged and faces the turning station 2 and the cleaning station 3. Two roller groups are installed on the mounting plate 101, one roller group is located above the turning station 2, and the other roller group is located above the cleaning station 3. Each roller group includes a plurality of rollers 102. Two second motors 103 are provided on the lifting platform 10, one second motor 103 is used to drive any roller 102 in one roller group to rotate, and the other second motor 103 is used to drive any roller 102 in another roller group to rotate. A driving belt 11 is also provided on the outside of each roller group, and the driving belt 11 is polygonal under the tension of the plurality of rollers 102. As the lifting platform 10 descends, the driving belt 11 will contact the top of the commutator 5, and the commutator 5 will roll on a pair of support seats 71 under the rubbing of the driving belt 11.

[0055] Figure 3 It is a schematic stereogram of the turning station. Figure 4 This is a reference diagram of the assembly status of the turning station. Figure 3 and Figure 4 The turning station 2 includes a tool holder 22 driven by an electric slide 21. The electric slide 21 can drive the tool holder 22 to move arbitrarily in a horizontal plane. A tool 23 is installed on the tool holder 22. The turning station 2 is provided with a dust collection mechanism, which includes a fixed shell 24 and a movable shell 25. The fixed shell 24 is fixedly arranged on the machine 1, and the opening of the fixed shell 24 is arranged upward. The movable shell 25 is connected to the mounting plate 101 through a bracket 310, and the opening of the movable shell 25 is arranged downward. When the lifting platform 10 descends, the movable shell 25 will cover the top of the fixed shell 24, so that the opening of the movable shell 25 will dock with the opening of the fixed shell 24, so that the fixed shell 24 and the movable shell 25 are combined to form a dust cover. A notch 250 is provided on the side of the movable housing 25 facing the tool 23. When the fixed housing 24 is docked with the movable housing 25, the shaft of the commutator 5 will be covered inside the dust cover, and the electric slide 21 drives the tool 23 to pass through the notch 250 and insert into the inside of the dust cover to turn the end of the commutator 5. A dust suction pipe 240 is provided at the bottom of the fixed housing 24. Most of the waste chips generated during the turning process will be sucked by the dust suction pipe 240, and a small amount will adhere to the surface of the commutator 5.

[0056] Figure 5 yes Figure 2 A schematic diagram of the enlarged structure at A in the middle. Figure 5 Combined with Figure 2After the turning of the commutator 5 is completed, the lifting platform 10 is lifted so that the movable housing 25 is away from the material parking mechanism 7 at the rear side of the turning station 2. At this time, the commutator 5 can be transferred to the material parking mechanism 7 at the rear side of the cleaning station 3 through the material transfer mechanism 6. The cleaning station 3 includes a roller brush 32 driven by a first motor 31. The first motor 31 is also connected to the mounting plate 101 through a bracket 310. The roller brush 32 is disc-shaped. When the lifting platform 10 descends again and the driving belt 11 rubs the commutator 5 on the material parking mechanism 7 at the rear side of the cleaning station 3, the first motor 31 starts to work, so that the roller brush 32 can reliably brush away the waste chips adhering to the surface of the commutator 5. Since the axis of the roller brush 32 is perpendicular to the axis of the commutator 5, the waste chips brushed off by the rolling of the roller brush 32 will also fly away from the commutator 5 along the axial direction of the commutator 5, thereby ensuring reliable cleaning of the current commutator 5 while effectively preventing the brushed waste chips from adhering to other commutators 5 and causing secondary pollution.

[0057] Figure 6 This is a reference diagram of the dust sweeping mechanism's assembly status. Figure 7 is a schematic three-dimensional diagram of the dust sweeping mechanism. Figure 6 and Figure 7 Combined with Figure 1 A dust sweeping mechanism for sweeping away waste debris on the surface of the driving belt 11 is provided on the outer side of the driving belt 11 located at the rear side of the cleaning station 3. The dust sweeping mechanism includes an upper clamping plate 33 and a lower clamping plate 34. A waist hole 1011 is provided on the mounting plate 101. A bolt 1012 is passed through the waist hole 1011. The upper clamping plate 33 and the lower clamping plate 34 can be fixed to the mounting plate 101 by the bolt 1012. Moreover, the position of the upper clamping plate 33 and the lower clamping plate 34 can be adjusted by sliding the bolt 1012 in the waist hole 1011, so that the driving belt 11 can be passed between the upper clamping plate 33 and the lower clamping plate 34. An exhaust pipe 332 is provided on the top of the upper clamp plate 33 and an air intake port 331 is provided on the bottom. The exhaust pipe 332 exhausts air and forms a negative pressure at the air intake port 331. An air blowing port 341 is provided on the top of the lower clamp plate 34 and an air inlet pipe 342 is provided on the bottom. The air inlet pipe 342 takes in air and blows air in the direction of the upper clamp plate 33 through the air blowing port 341. In this way, air blowing from the air blowing port 341 and air inhalation from the air intake port 331 will form an air curtain between the upper clamp plate 33 and the lower clamp plate 34. When the driving belt 11 passes through the air curtain, the waste chips adhered to its surface will be blown away and sucked away by the air intake port 331.

[0058] Figure 8 This is a reference diagram of the assembly status of the vertical plate and the rotating tube. Figure 8 Combined with Figure 7Furthermore, an L-shaped vertical plate 35 is provided on the mounting plate 101, the horizontal end of the vertical plate 35 is connected to the mounting plate 101, the vertical end of the vertical plate 35 is located outside the upper clamping plate 33 and the lower clamping plate 34, and a rotating tube 352 is penetrated through the vertical end of the vertical plate 35, one end of the rotating tube 352 is connected to the suction pipe 3522 through a rotating joint 3521, and the other end of the rotating tube 352 extends between the upper clamping plate 33 and the driving belt 11, and the other end of the rotating tube 352 is provided with bristles 3523 and suction holes 3524, and the bristles 3523 and the suction ports 331 are alternately arranged and ringed on the outer wall of the rotating tube 352. The suction ports 331 on the upper clamping plate 33 are located on both sides of the bottom of the upper clamping plate 33, and the end of the rotating tube 352 is located between the two suction ports 331. A third motor 351 is also provided at the vertical end of the vertical plate 35. A transmission mechanism is provided between the third motor 351 and the rotating tube 352, so that the third motor 351 can drive the rotating tube 352 to rotate. During the rotation of the rotating tube 352, the air suction pipe 3522 sucks air and generates negative pressure at the air suction hole 3524, so that the bristles 3523 in contact with the driving belt 11 can reliably brush the driving belt 11, and the waste scraps brushed out will be immediately sucked out by the air suction hole 3524. At the same time, the air curtain between the air suction port 331 and the driving belt 11 can form a limiting effect on the waste scraps, ensuring that the waste scraps brushed out by the bristles 3523 can be completely absorbed by the air suction hole 3524, effectively preventing the waste scraps from causing secondary pollution. Under the connection of the rotary joint 3521, the rotating tube 352 can keep rotating while the suction pipe 3522 can keep still, thereby effectively preventing the suction pipe 3522 from getting entangled, and ensuring that the suction pipe 3522 can reliably generate negative pressure at the suction hole 3524 and absorb waste chips.

Fig. 9 Combined with Figure 1 After the commutator 5 is cleaned, the lifting platform 10 is lifted, and the commutator 5 can be transferred to the material parking mechanism 7 on the front side of the conveyor belt 8 through the material transfer mechanism 6, and then the commutator 5 is grabbed and placed on the conveyor belt 8 by the mechanical gripper 9 and transported to the inspection station 4. The inspection station 4 includes a visual inspection mechanism 40, which is arranged on the rear side of the conveyor belt 8. The visual inspection mechanism 40 is used to take pictures and analyze the commutator 5, which greatly improves the accuracy of the inspection of the turning and cleaning results of the commutator 5.
