Description

Technical Field

[0001] This invention relates to the field of motor magnetic pole technology, specifically an automatic deburring device for magnetic poles. Background Technology

[0002] Figure 8 The image shows the magnetic poles of a motor. After production, burrs will remain on their outer surface, so these burrs need to be cleaned.

[0003] Since the magnetic pole consists of two parts, the pole body and the pole shoe, deburring is required at multiple workstations. Currently, there are two methods for transferring between workstations. The first is manual. The magnetic poles are first stacked at one workstation. After one part of the magnetic pole is cleaned, it is stacked in a material box and transported to the next workstation. The second method is via conveyor belt. Each workstation is connected by a conveyor belt. When the deburring of one part of the magnetic pole is completed, the worker places the magnetic pole on the conveyor belt and transports it to the next workstation.

[0004] The two methods described above involve high labor costs and high labor intensity. Therefore, how to reduce labor costs and labor intensity has become an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0005] To address the technical problems in the background art, this invention discloses an automatic deburring device for magnetic poles.

[0006] This invention provides an automatic deburring device for magnetic poles, comprising: (The following are listed in sequence)

[0007] Vibratory feeder, used to transport magnetic poles;

[0008] The first deburring device is used to grab the magnetic pole at the outlet of the vibratory feeder and remove the burrs on the four edges at the lower end of the pole body. Then the cleaned magnetic pole is placed on the first conveyor.

[0009] The second deburring device is used to grab the magnetic pole at the tail of the first conveyor and place it on the tooling to remove the burrs on the four corners and two wide sides of the upper end face of the pole shoe. Then the cleaned magnetic pole is placed on the second conveyor.

[0010] The second conveyor transports the magnetic poles to the next workstation.

[0011] A vibratory feeder is used for automatic feeding of magnetic poles; a first deburring device and a second deburring device achieve automatic removal of magnetic pole burrs under the action of a first conveyor; a second conveyor is used for automatic unloading of the cleaned magnetic poles; this invention replaces manual labor, which not only improves work efficiency, but also reduces labor costs and labor intensity.

[0012] The specific structure of the first deburring device is as follows: it includes a first turntable driven by a first motor; four evenly distributed first pneumatic fingers are installed on the first turntable for gripping magnetic poles; the first pneumatic fingers are driven to rise and fall by a first cylinder; the first deburring device has four stations corresponding to the first turntable, in the following order: the outlet of the vibratory plate is located at the first station; the second station is equipped with an annularly arranged sandpaper, driven by a second motor, for removing burrs on the long side of the lower end of the pole body; the third station is equipped with two symmetrically arranged, frustum-shaped first grinding wheels, driven by a third motor, for removing burrs on the short side of the lower end of the pole body; the head end of the first conveyor is located at the fourth station.

[0013] The specific structure of the second deburring device is as follows: it includes a second turntable driven by a fourth motor; tooling is evenly distributed on the upper end of the second turntable; the second deburring device has four stations corresponding to the second turntable, namely: the fifth station, which is equipped with a second pneumatic finger, driven to lift by a second cylinder and driven to move horizontally by a first linear slide, used to grab the magnetic pole on the first conveyor and place it on the tooling; the sixth station, which is equipped with two symmetrically arranged, frustum-shaped second grinding wheels, driven to rotate by a fifth motor and driven to move horizontally by a third cylinder. The first station is used to remove burrs from the short side of the upper end of the pole shoe; the seventh station is equipped with four third grinding wheels, which are driven to rotate by the sixth motor, move horizontally by the fourth cylinder, and lift by the fifth cylinder, and are used to remove burrs from the four corners of the upper end of the pole shoe; the fourth cylinder is designed so that the third grinding wheels cover the area of ​​the four corners of the upper end of the pole shoe, making it easy to clean; the eighth station is equipped with a third pneumatic finger, which is driven to lift by the sixth cylinder and move horizontally by the second linear slide, and is used to grab the cleaned magnetic pole and place it at the beginning of the second conveyor.

[0014] The specific structure of the tooling is as follows: it includes a base plate with a support plate on its upper end; the upper end of the support plate is arc-shaped to fit the lower end face of the pole body; baffles are provided on the four sides of the support plate for limiting the side position of the pole body; a vertically arranged positioning rod is provided at the center of the support plate for connecting to the through hole on the magnetic pole to achieve positioning.

[0015] If the fifth motor is directly connected to the second grinding wheel, it will occupy the space of the second turntable and is prone to collision; moreover, the second grinding wheel will experience uneven force when grinding burrs, resulting in incomplete burr removal. Based on this, the further design is as follows: the second grinding wheel is symmetrically mounted on the second coupling shaft; a driven synchronous pulley is installed at the center of the second coupling shaft; a driving synchronous pulley is installed at the drive end of the fifth motor; the driven synchronous pulley and the driving synchronous pulley are linked by a meshing synchronous belt.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0029] like Figure 1 and Figure 4 As shown, the present invention is an automatic deburring device for magnetic poles, comprising a vibrating plate 1, a first deburring device, and a second deburring device arranged in sequence.

[0030] The first deburring device includes a first frame, on which a column is mounted on a platform. A first turntable 6 is mounted on the top of the column, and a first rotating shaft is provided at its lower end. The first rotating shaft is rotatably connected to the column via bearings and is also driven to rotate by a first motor 5.

[0031] like Figure 2 As shown, four rotationally symmetrical first connecting plates are mounted on the first turntable 6. The upper ends of the connecting plates are fixedly connected to the turntable by bolts, and the lower ends are equipped with first cylinders 8: dual-shaft cylinders. The drive end of the first cylinder 8 is equipped with a first pneumatic finger 7.

[0032] The outer side of the first turntable 6 has four workstations corresponding to the first pneumatic fingers 7, evenly distributed as follows:

[0033] The first workstation has the outlet pipe of the vibratory feeder 1.

[0034] Second workstation, such as Figure 2 As shown, a first support is installed, on which a driving roller and a driven roller are installed side by side. A ring of sandpaper 9 is sleeved on the driving roller and the driven roller, thereby achieving linkage. The driving roller is driven to rotate by a second motor 10, thereby driving the sandpaper 9 to move in a ring, which is used to remove burrs on the long side of the lower end of the electrode body 102.

[0035] The third work station, such as Figure 2 As shown, a second support is installed, and a first coupling is mounted on the second support, achieving a rotatable connection through bearings. Two symmetrically arranged, frustum-shaped first grinding wheels 11 are sleeved on the first coupling, with their constricted ends facing each other. One end of the first coupling is connected to a third motor 26, which drives the first grinding wheels 11 to rotate, used to remove burrs on the short side of the lower end of the electrode body 102;

[0036] The fourth station is equipped with the first conveyor 2, the head of which is located directly below the first pneumatic finger 7.

[0037] The second deburring device includes a second frame with a platform in the middle. A second turntable 13 is mounted on the platform, and a second rotating shaft is located at its lower end. The second rotating shaft is rotatably connected to the platform via bearings and is also driven to rotate by a fourth motor 12.

[0038] The second turntable 13 is equipped with four rotationally symmetrical fixtures 3, such as... Figure 6As shown, it includes a circular base plate 31, with a support plate 32 at its upper end; the upper end of the support plate 32 is arc-shaped to fit against the lower end face of the pole body 102. Baffles 33 are provided on the four sides of the support plate 32 for lateral positioning of the pole body 102. A vertically arranged positioning rod 34 is provided at the center of the support plate 32 for engaging with the through hole 104 on the magnetic pole 101 to achieve positioning.

[0039] The outer side of the second turntable 13 has four workstations corresponding to the tooling 3 evenly distributed, as follows:

[0040] The fifth workstation, such as Figure 5 As shown, a horizontally arranged first linear slide 16 is installed on the crossbeam above it, and a vertically arranged second connecting plate is installed on the slide. A second cylinder 15 (a dual-shaft cylinder) is installed at the lower end of the second connecting plate. A second pneumatic finger 14 is installed at the drive end of the second cylinder 15; the tail end of the first conveyor 2 is located at the fifth station.

[0041] The sixth workstation, such as Figure 7 As shown, a third support is installed, and a second movable plate is installed on the third support, which is guided by a linear guide rail. A third cylinder 19 is installed at the outer end of the third support to drive the second movable plate to move horizontally. A second coupling shaft 35 is installed at the inner end of the second movable plate, which is rotatably connected by a bearing. Two symmetrically arranged, frustum-shaped second grinding wheels 17 are sleeved on the second coupling shaft 35, with their constricted ends facing each other. A driven synchronous pulley 36 is installed at the center of the second coupling shaft 35. A fifth motor 23 is installed on the third support, and a driving synchronous pulley 37 is installed at its driving end. The driving and driven synchronous pulleys are linked by a meshing synchronous belt 38 to remove burrs on the short side of the upper end of the pole shoe 103. The fifth motor 23 can be moved away from the second grinding wheels 17 by the synchronous pulley transmission, so as not to occupy the space of the second turntable 13 and avoid collision. Moreover, the position of the driven synchronous pulley 36 makes the two second grinding wheels 17 evenly stressed when grinding burrs, so that the burrs are not completely removed.

[0042] The seventh workstation, such as Figure 9 and Figure 10As shown, a third connecting plate is installed on the crossbeam above it, and a lifting plate is installed on the third connecting plate, which is guided by a linear guide. A fifth cylinder 23 is installed at the upper end of the third connecting plate to drive the lifting plate to rise and fall. A connecting frame is installed at the lower end of the lifting plate, which is slidably connected to the lifting plate through a linear guide rail. A fourth cylinder 22 is installed at the lower end of the lifting plate to drive the connecting frame to move horizontally. Four sixth motors 21 are installed on the connecting frame, with their driving ends facing each other and symmetrically distributed. A third grinding wheel 20 is installed at the driving end of the sixth motor 21, corresponding to one corner of the upper end of the pole shoe 103, to remove burrs from the four corners of the upper end of the pole shoe 103. The fourth cylinder 22 is positioned so that the third grinding wheel 20 covers the area of ​​the four corners of the upper end of the pole shoe 103, making it easy to clean.

[0043] The eighth workstation, such as Figure 5 As shown, a horizontally arranged second linear slide is installed on the crossbeam above it, and a vertically arranged third connecting plate is installed on the slide; a sixth cylinder 25 (a dual-shaft cylinder) is installed at the lower end of the third connecting plate; a third pneumatic finger 24 is installed at the drive end of the sixth cylinder 25; the head end of the second conveyor 4 is located at the eighth station.

[0044] The operation steps of this invention are as follows: 1. The vibratory feeder 1 transports the magnetic pole 101 to the first station; 2. The first pneumatic finger 7 at the first station grasps the magnetic pole 101; 3. The first turntable 6 rotates, transporting the magnetic pole 101 to the second station, and sandpaper 9 removes the burrs on the lower long side of the pole body 102; 4. The first turntable 6 rotates, transporting the magnetic pole 101 to the third station, and the first grinding wheel 11 removes the burrs on the lower short side of the pole body 102; 5. The first turntable 6 rotates, transporting the magnetic pole 101 to the fourth station; 6. The first pneumatic finger 7 descends and releases the magnetic pole 101, which falls into the head end of the first conveyor 2; 7. The first conveyor 2 transports the magnetic pole 101 to the fifth station; 8. The fifth station... The second pneumatic finger 14 of the first conveyor 2 picks up the magnetic pole 101 at the tail end of the first conveyor 2 and places it on the fixture 3; 8. The second turntable 13 rotates to transport the magnetic pole 101 to the sixth station; 9. The second grinding wheel 17 rotates to remove burrs on the short side of the upper end of the pole shoe 103; 9. The second turntable 13 rotates to transport the magnetic pole 101 to the seventh station; 10. The fourth grinding wheel rotates and moves horizontally to remove burrs on the four corners of the upper end of the pole shoe 103; 11.

The third pneumatic finger 24 removes the magnetic pole 101 from the fixture 3 and places it at the head end of the second conveyor 4; 13. The second conveyor 4 transports the magnetic pole 101 to the next station.

[0045] This invention replaces manual labor, enabling automatic feeding, deburring, and unloading of the magnetic pole 101. This not only improves work efficiency but also reduces labor costs and labor intensity.
