Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing technology, specifically a grinding device for motor manufacturing. Background Technology

[0002] An electric motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. In the production process of an electric motor, grinding its casing is an indispensable step, so grinding equipment is required.

[0003] CN216265032U discloses a device for grinding the edge of a motor housing, including a base with an operating table fixedly mounted on its upper end. A frame is fixedly mounted on the upper end of the operating table, and a turntable is disposed on one side of the upper end of the operating table. A ball bearing slide rail is provided at the junction of the turntable and the operating table. A servo motor is connected to the lower part of the turntable via a rotating shaft. A longitudinally placed support rod is fixed at the center of the upper end of the turntable, and a cylinder is installed around the outer wall of the support rod. In use, the telescopic rod can freely extend and retract under the push of the cylinder, and the rubber block at the end provides elastic support to the inner wall of the motor housing, thereby achieving a stable support for the motor housing. The even arrangement of the three cylinders allows the motor housing to be kept in the center position of the turntable. The servo motor can rotate the turntable horizontally via the rotating shaft, and the turntable can drive the motor housing above it to rotate synchronously.

[0004] The aforementioned grinding device for motor housing can only grind the outer surface of the motor housing, and cannot grind the inner wall of the motor housing. To grind the inner wall of the motor housing, the motor housing needs to be transferred to another device to complete the grinding, which increases the operation process and reduces the overall production efficiency. Therefore, a grinding device for motor production is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background art, this utility model proposes a grinding device for motor production.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A grinding device for motor production, comprising a support frame, a base fixedly connected to the support frame, a motor mounted on the bottom side wall of the base, a rotating shaft connected to the output end of the motor, a rotating disk fixedly connected to the top end of the rotating shaft, an inner clamping mechanism and an outer clamping mechanism provided on the rotating disk, the inner clamping mechanism comprising a fixed column, a fixed column mounted at the top center of the rotating disk, a square body fixedly connected to the top end of the fixed column, pneumatic cylinders mounted on the four side walls of the square body, a pneumatic rod mounted at the working end of each pneumatic cylinder, and an inner clamping plate fixedly connected to the other end of each pneumatic rod, the outer clamping mechanism comprising a groove, a groove formed on the rotating disk, a bidirectional lead screw rotatably mounted in the groove, sliders sleeved at both ends of the bidirectional lead screw, the sliders being disposed within the groove, and an outer clamping mechanism fixedly connected to the top end of each slider. A first motor is mounted on the periphery of the rotating disk. The output end of the first motor is connected to one end of a bidirectional lead screw. When grinding the inner wall of the motor housing, an outer clamping mechanism is used to clamp and fix the motor housing, while the inner clamping mechanism is in a retracted state. Starting the first motor causes the bidirectional lead screw to rotate, which in turn causes the two sliders to move the two outer clamping plates closer together until they contact the outer surface of the motor housing. This clamps and fixes the outer surface of the motor housing, facilitating subsequent rotational grinding of the inner wall. When grinding the outer surface of the motor housing, the outer clamping plates are first returned to their initial positions. The inner clamping mechanism is then used to clamp and fix the motor housing. A pneumatic cylinder is activated, causing the inner clamping plates to expand outwards until they contact the inner wall of the motor housing. This clamps and fixes the inner wall of the motor housing, facilitating subsequent rotational grinding of the outer surface.

[0007] Preferably, a T-shaped track is fixed to the top side of the base, and a movable plate is slidably mounted on the T-shaped track. A first groove is formed on the movable plate, and a first lead screw is rotatably mounted within the first groove. A second motor is mounted on the top of the movable plate, and the output end of the second motor is connected to the top of the first lead screw. A lifting frame is sleeved on the first lead screw, and a third motor is mounted on the top side of the lifting frame. An inner grinding wheel is mounted on the output end of the third motor via a rotating shaft. After the external clamping mechanism clamps and fixes the motor housing, the inner wall of the motor housing is ground. The fourth motor is activated, causing the first threaded rod to rotate, which in turn forces the movable plate to move the inner grinding wheel horizontally until the inner grinding wheel is directly above the inner wall. Then, the second motor is activated, causing the first lead screw to rotate, which forces the lifting frame to move the inner grinding wheel vertically downward until the inner grinding wheel is completely in contact with the inner wall of the motor. Then, the third motor is activated, causing the inner grinding wheel to rotate. At the same time, the electric motor is activated, causing the rotating disk to rotate, which in turn causes the clamped and fixed motor housing to rotate. Through the rotation of the motor housing, the inner wall of the motor housing can be fully rotated and ground.

[0008] Preferably, both ends of the T-shaped track are fixedly connected to baffles, and the two baffles are rotatably mounted with a first threaded rod, which passes through the movable plate. A fourth motor is mounted on one of the baffles, and the output end of the fourth motor is connected to one end of the first threaded rod. When grinding the inner wall of the motor housing, the fourth motor is started, causing the first threaded rod to rotate, which in turn forces the movable plate to drive the inner grinding wheel to move horizontally. This allows the horizontal position of the inner grinding wheel to be adjusted, facilitating the grinding of the inner wall of the motor housing.

[0009] Preferably, the top side of the base has a through groove, a movable block is provided in the through groove, a vertical plate is fixed to the top of the movable block, a second sliding groove is provided on the vertical plate, a second lead screw is rotatably installed in the second sliding groove, a fifth motor is installed at the top of the vertical plate, the output end of the fifth motor is connected to the top of the second lead screw, a lifting plate is sleeved on the second lead screw, an installation groove is provided at the end of the lifting plate, a sixth motor is provided in the installation groove, and an outer grinding ball is installed at the output end of the sixth motor. After the inner wall of the motor housing is clamped and fixed by the inner clamping mechanism, when grinding the outer surface of the motor housing, the seventh motor is started, causing the second threaded rod to rotate, forcing the movable block to drive the vertical plate to move horizontally, thereby moving the outer grinding ball to contact the outer surface of the motor housing. Then, the sixth motor is started, causing the outer grinding ball to rotate, and the fifth motor is started, causing the second lead screw to rotate, thereby causing the lifting plate to drive the outer grinding ball to reciprocate up and down. With the cooperation of the rotating mechanism, the grinding of the outer surface of the motor housing can be completed.

[0010] Preferably, two fixing plates are fixedly connected to the bottom side of the through slot. The two fixing plates are rotatably mounted with a second threaded rod, which passes through the bottom end of the movable block. A seventh motor is mounted on one of the fixing plates. The output end of the seventh motor is connected to one end of the second threaded rod. When grinding the outer surface of the motor housing, the seventh motor is started, causing the second threaded rod to rotate. This forces the movable block to move the vertical plate horizontally, thereby causing the outer grinding ball to move as well. This allows the horizontal position of the outer grinding ball to be adjusted, facilitating the grinding of the outer surface of the motor housing.

[0011] The advantages of this utility model are:

[0012] 1. When grinding the inner wall of a motor housing, this utility model requires the use of an external clamping mechanism to clamp and fix the motor housing, while the internal clamping mechanism is in a retracted state. Starting the first motor causes the bidirectional lead screw to rotate, which in turn causes the two sliders to move the two external clamping plates closer together until they contact the outer surface of the motor housing. This clamps and fixes the outer surface of the motor housing, facilitating subsequent rotary grinding of the inner wall. When grinding the outer surface of the motor housing, the external clamping plates are first returned to their initial positions. The internal clamping mechanism is then used to clamp and fix the motor housing. Starting the pneumatic cylinder causes the internal clamping plates to expand outwards until they contact the inner wall of the motor housing, thus clamping and fixing the inner wall and facilitating subsequent rotary grinding of the outer surface.

[0013] 2. When in use, this utility model, through the cooperation of the inner and outer clamping mechanisms and the inner and outer grinding mechanisms, can complete the grinding of the inner and outer surfaces of the motor housing on the same equipment, without having to transfer the motor housing from one equipment to another for grinding, which greatly improves the grinding efficiency.

[0022] 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 scope of protection of the present utility model.

[0023] Please see Figure 1-6As shown, a grinding device for motor production includes a support frame 1, a base 2 fixedly connected to the support frame 1, a motor 3 mounted on the bottom side wall of the base 2, a rotating shaft connected to the output end of the motor 3, a rotating disk 4 fixedly connected to the top end of the rotating shaft, an inner clamping mechanism and an outer clamping mechanism provided on the rotating disk 4, the inner clamping mechanism including a fixed column 5, the fixed column 5 being mounted at the top center of the rotating disk 4, a square body 6 fixedly connected to the top end of the fixed column 5, and pneumatic cylinders 7 mounted on the four side walls of the square body 6. Each pneumatic cylinder 7 has a pneumatic rod mounted on its working end, and an inner clamping plate 8 is fixedly connected to the other end of each pneumatic rod. The outer clamping mechanism includes a groove 9. A groove 9 is provided on the rotating disk 4, and a bidirectional lead screw 10 is rotatably mounted in the groove 9. Both ends of the bidirectional lead screw 10 are fitted with sliders, and the sliders are set in the groove 9. The tops of the two sliders are fixedly connected to an outer clamping plate 12. A first motor 11 is mounted on the periphery of the rotating disk 4, and the output end of the first motor 11 is connected to one end of the bidirectional lead screw 10. During operation, when grinding the inner wall of the motor housing, an external clamping mechanism is needed to clamp and fix the motor housing, while the internal clamping mechanism is in a retracted state. The first motor 11 is started, causing the bidirectional lead screw 10 to rotate, which in turn causes the two sliders to move the two external clamping plates 12 closer together until the two external clamping plates 12 contact the outer surface of the motor housing. At this point, the first motor 11 stops operating, thus clamping and fixing the outer wall of the motor housing, facilitating subsequent rotary grinding of the inner wall. After grinding the inner wall of the motor housing, when grinding the outer surface, the external clamping plates 12 are first returned to their initial position. The internal clamping mechanism is then used to clamp and fix the motor housing. The pneumatic cylinder 7 is started, causing the pneumatic rod to expand the internal clamping plate 8 outwards until the internal clamping plate 8 touches the inner wall of the motor housing. At this point, the pneumatic cylinder 7 stops operating, thus clamping and fixing the inner wall of the motor housing, facilitating subsequent rotary grinding of the outer surface.

[0024] A T-shaped track 13 is fixedly connected to the top side of the base 2. A movable plate 14 is slidably mounted on the T-shaped track 13. A first groove 15 is opened on the movable plate 14. A first lead screw 17 is rotatably installed in the first groove 15. A second motor 16 is installed at the top of the movable plate 14. The output end of the second motor 16 is connected to the top of the first lead screw 17. A lifting frame 18 is sleeved on the first lead screw 17. A third motor 19 is installed on the top side of the lifting frame 18. An inner grinding wheel 20 is installed at the output end of the third motor 19 through a rotating shaft. Baffles 21 are fixedly connected to both ends of the T-shaped track 13. A first threaded rod 23 is rotatably installed on the two baffles 21, and the first threaded rod 23 passes through the movable plate 14. A fourth motor 22 is installed on one of the baffles 21. The output end of the fourth motor 22 is connected to one end of the first threaded rod 23. When the motor housing is externally clamped and fixed by the external clamping mechanism, the fourth motor 22 is started to rotate the first threaded rod 23 when the inner wall of the motor housing is being polished. This causes the movable plate 14 to move on the T-shaped track 13, which in turn causes the movable plate 14 to drive the inner polishing wheel 20 to move horizontally until the inner polishing wheel 20 is directly above the inner wall. Then, the second motor 16 is started to rotate the first lead screw 17, which causes the lifting frame 18 to drive the inner polishing wheel 20 to move vertically downward until the inner polishing wheel 20 is completely lowered and in contact with the inner wall of the motor. Then, the third motor 19 is started to rotate the inner polishing wheel 20. At the same time, the motor 3 is started to rotate the rotating disk 4, which in turn causes the clamped and fixed motor housing to rotate. Through the rotation of the motor housing, the inner wall of the motor housing can be fully rotated and polished.

[0025] A through groove 24 is provided on the top side of the base 2. A movable block 25 is provided in the through groove 24. A vertical plate 26 is fixed to the top of the movable block 25. A second sliding groove 27 is provided on the vertical plate 26. A second lead screw 29 is rotatably installed in the second sliding groove 27. A fifth motor 28 is installed at the top of the vertical plate 26. The output end of the fifth motor 28 is connected to the top of the second lead screw 29. A lifting plate 30 is sleeved on the second lead screw 29. A mounting groove 31 is provided at the end of the lifting plate 30. A sixth motor is provided in the mounting groove 31. An external grinding ball 32 is installed at the output end of the sixth motor. Two fixing plates 33 are fixed to the bottom side of the port of the through groove 24. A second threaded rod 35 is rotatably installed on the two fixing plates 33. The second threaded rod 35 passes through the bottom end of the movable block 25. One of the fixing plates 33 is equipped with... There is a seventh motor 34, the output end of which is connected to one end of the second threaded rod 35. During operation, after the inner wall of the motor housing is clamped and fixed by the inner clamping mechanism, when grinding the outer surface of the motor housing, the seventh motor 34 is started, causing the second threaded rod 35 to rotate. This forces the movable block 25 to drive the vertical plate 26 to move horizontally, which in turn causes the outer grinding ball 32 to move horizontally as well. After the outer grinding ball 32 moves to contact the outer surface of the motor housing, the seventh motor 34 stops working. Then, the sixth motor is started, causing the outer grinding ball 32 to rotate. At the same time, the fifth motor 28 is started, causing the second lead screw 29 to rotate. This causes the lifting plate 30 to drive the outer grinding ball 32 to reciprocate up and down. With the cooperation of the rotating mechanism, the grinding of the outer surface of the motor housing can be completed.

[0026] Working Principle: The aforementioned motor housing grinding device can only grind the outer surface of the motor housing, not the inner wall. To grind the inner wall, the motor housing needs to be transferred to another machine, increasing the operational steps and reducing overall production efficiency. Therefore, this invention proposes a motor manufacturing grinding device. To enable grinding of both the inner and outer surfaces of the motor housing on the same machine, an external clamping mechanism is used to clamp and fix the motor housing when grinding the inner wall. The internal clamping mechanism is in a retracted state. The first motor 11 is activated, causing the bidirectional lead screw 10 to rotate. This causes the two sliders to move the two external clamping plates 12 closer together until they contact the outer surface of the motor housing. The first motor 11 stops operating, thereby clamping and fixing the motor housing externally. After the motor housing is clamped and fixed externally, when grinding the inner wall of the motor housing, the fourth motor 22 is started, causing the first threaded rod 23 to rotate, which in turn forces the movable plate 14 to move on the T-shaped track 13, which in turn causes the movable plate 14 to drive the inner grinding wheel 20 to move horizontally until the inner grinding wheel 20 is directly above the inner wall. Then, the second motor 16 is started, causing the first lead screw 17 to rotate, which forces the lifting frame 18 to drive the inner grinding wheel 20 to move vertically downward until the inner grinding wheel 20 is completely lowered and in contact with the inner wall of the motor. Then, the third motor 19 is started, causing the inner grinding wheel 20 to rotate. At the same time, the motor 3 is started, causing the rotating disk 4 to rotate, which in turn causes the clamped and fixed motor housing to rotate. Through the rotation of the motor housing, the inner wall of the motor housing can be fully rotated and ground.

[0027] After the inner wall of the motor housing is polished, when polishing the outer surface of the motor housing, first return the outer clamping plate 12 to its initial position. The inner clamping mechanism is then used to clamp and fix the motor housing. The pneumatic cylinder 7 is activated, causing the pneumatic rod to expand the inner clamping plate 8 outwards until it contacts the inner wall of the motor housing. The pneumatic cylinder 7 then stops, thus clamping and fixing the inner wall of the motor housing. After the inner wall of the motor housing is clamped and fixed, when polishing the outer surface of the motor housing, the seventh motor 34 is activated, causing the second threaded rod 35 to rotate. This forces the movable block 25 to move the vertical plate 26 horizontally, thereby causing the outer polishing ball 32 to move accordingly. The machine moves horizontally until the outer grinding ball 32 contacts the outer surface of the motor housing. Then, the seventh motor 34 stops operating, and the sixth motor is started to make the outer grinding ball 32 rotate. At the same time, the fifth motor 28 is started to make the second lead screw 29 rotate, which in turn causes the lifting plate 30 to drive the outer grinding ball 32 to reciprocate up and down. With the cooperation of the rotating mechanism, the outer surface of the motor housing can be polished. Through the cooperation of the inner and outer clamping mechanisms and the inner and outer polishing mechanisms, the inner and outer surfaces of the motor housing can be polished on the same machine without having to transfer the motor housing from one machine to another for polishing, which greatly improves the polishing efficiency.
