Description

Technical Field

[0001] This utility model relates to the field of rotor grinding technology, and in particular to a rotor grinding device. Background Technology

[0002] A rotor grinding device is a piece of equipment used to perform surface treatment on rotating parts such as motor rotors. It removes oxide layers, rust, and burr defects from the rotor surface, making the rotor surface smoother and flatter. This helps reduce frictional resistance during rotor operation, lowers energy loss, and improves motor efficiency. Automated rotor grinding devices can achieve continuous and efficient grinding operations, greatly improving production efficiency. A precise control system can ensure the stability and consistency of grinding quality, reducing scrap rates.

[0003] A search revealed Chinese patent publication number CN212918831U, which discloses a rotor grinding device. The device includes a base, a collection structure, and a grinding structure. The collection structure is mounted on the upper surface of the base, and the grinding structure is mounted on the collection structure. The collection structure also includes a collection groove. This invention features a first grinding head, a second grinding head, and a first gear. The first and second grinding heads have different structures and side lengths. A motor drives a first rotating rod to rotate, which in turn drives the first gear to rotate. Since the first gear meshes with the second gear, the second gear rotates along with the first gear, which in turn drives the second rotating rod to rotate. The first rotating rod drives the first grinding head to rotate, and simultaneously the second rotating rod drives the second grinding head to rotate. This allows for different grinding heads to be used to grind the rotor without needing to change grinding heads, improving grinding efficiency and providing convenience for operators. However, because the rotor's shape is similar to a cylinder, the inner and outer walls of the rotor are processed simultaneously during manufacturing, leaving slag on both sides. Simply changing different grinding heads cannot effectively grind the entire surface of the rotor. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a rotor grinding device, which aims to improve the problem that, since the rotor is similar in shape to a cylinder, the inner and outer walls of the rotor are processed simultaneously during processing, leaving slag on both the inner and outer walls. Simply changing different grinding heads cannot effectively grind the entire surface of the rotor.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a rotor grinding device, comprising a carrier plate, a base plate fixedly connected to the bottom of the carrier plate, a rotating motor fixedly connected to the bottom wall of the base plate, the output end of the rotating motor penetrating through the middle of the bottom wall of the base plate and fixedly connected to a drive shaft, a driven wheel one rotatably connected to the left side of the top wall of the base plate, and a driven wheel two rotatably connected to the right side of the top wall of the base plate, the drive shaft being meshed with driven wheel one and driven wheel two via a belt, and multiple electric motors being fixedly connected at equal intervals to the top outer wall of driven wheel one. The telescopic rods are equipped with rubber push strips fixedly connected to the far ends of the multiple electric telescopic rods. Multiple fixing frames are fixedly connected to the left and right sides of the top wall of the carrier plate. Brush cylinders are fixedly connected between adjacent fixing frames on the left side. A brush rod is fixedly connected to the top of the driven wheel. A fixing cylinder is fixedly connected between adjacent fixing frames on the right side. Multiple hydraulic rods are fixedly connected at equal intervals around the inner wall of the fixing cylinder. Rubber push strips are fixedly connected to adjacent ends of the multiple hydraulic rods. A movable gripping and placing mechanism is provided on the top of the carrier plate.

[0006] The above technical solution involves rotating the driven wheel 1 and driven wheel 2 via a rotating motor to grind the outside and inside of the rotor respectively, meeting different processing requirements and greatly improving the quality and efficiency of grinding in industrial production.

[0007] As a further description of the above technical solution:

[0008] The mobile gripping and placing mechanism includes a top plate, a telescopic column is fixedly connected to the middle of the bottom wall of the top plate, a fixing ring is fixedly connected to the bottom end of the telescopic column, a plurality of fixing strips are fixedly connected at equal intervals around the bottom wall of the fixing ring, a plurality of telescopic devices are fixedly connected to the adjacent side of the plurality of fixing strips, a clamping plate is fixedly connected to the adjacent end of the plurality of telescopic devices, and a hook is fixedly connected to the bottom end of the adjacent side of the plurality of clamping plates.

[0009] The above technical solution involves the top plate supporting the telescopic column for vertical extension and retraction. When the rotor needs to be gripped, multiple telescopic devices are activated simultaneously and extend towards the center. The telescopic devices push the clamping plate closer to the rotor. When the rotor needs to be placed, the telescopic devices retract, causing the clamping plate to release the rotor. This allows the mobile gripping and placement mechanism to efficiently complete the task of gripping and placing the rotor, improving the automation level and working efficiency of the entire rotor grinding device.

[0010] As a further description of the above technical solution:

[0011] A control console is fixedly connected to the front right end of the carrier plate, and multiple control buttons are fixedly connected to the top of the control console.

[0012] The above technical solution involves a control panel that serves as the central signal control panel for the entire grinding device. Multiple control buttons on its top control the telescopic column, telescopic device, rotary motor, electric telescopic rod, hydraulic rod, and tachometer.

[0013] As a further description of the above technical solution:

[0014] A tachometer is fixedly connected to the front left end of the carrier plate, and the tachometer is electrically connected to the control console.

[0015] Through the above technical solution: the tachometer is electrically connected to the control console, which can display the output speed of the rotating motor and the speed of driven wheel one and driven wheel two in real time.

[0016] As a further description of the above technical solution:

[0017] Each of the four corners of the bottom wall of the base plate is fixedly connected with a column, and each of the columns is fixedly connected with an anti-slip pad.

[0018] Through the above technical solution: the column supports the entire device, ensuring its stability during operation, while the anti-slip pad is used to reduce the vibration generated by the entire equipment during operation.

[0019] As a further description of the above technical solution:

[0020] A placement platform is fixedly connected to the middle of the inner bottom wall of the carrier plate, and a fixing column is fixedly connected to the middle of the inner bottom wall of the placement platform.

[0021] The above technical solution provides a temporary placement area for the rotor during the grinding process, facilitating the loading and unloading of the rotor by operators. The fixing column in the middle can fix the items placed on the placement platform to a certain extent and prevent them from accidentally slipping off.

[0022] As a further description of the above technical solution:

[0023] Anti-collision pads are fixedly connected to the four corners on the front side of the carrier plate, and the outer walls of the multiple anti-collision pads are all designed with rounded edges.

[0024] The above technical solution involves anti-collision pads located at the four corners of the front side of the carrier plate. The smooth outer wall design prevents operators from accidentally bumping into the corners of the carrier plate during operation and thus improves operational safety.

[0025] As a further description of the above technical solution:

[0026] The shape of the multiple anti-slip pads (20) is a circular design with a smaller top and a larger bottom, and the bottom wall of the multiple anti-slip pads (20) is made of frosted material.

[0027] Through the above technical solution: the anti-slip mat 20 adopts a circular design with a smaller top and a larger bottom, and the bottom wall is made of frosted material, which increases the friction with the ground, prevents the device from sliding during operation, and ensures the safety and reliability of the grinding process.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the driven wheel one and driven wheel two are driven to rotate by a rotating motor, which respectively grinds the outside and inside of the rotor to meet different processing requirements, greatly improving the quality and efficiency of grinding in industrial production.

[0030] 2. In this utility model, the telescopic column supported by the top plate extends and retracts vertically. When the rotor needs to be grasped, multiple telescopic devices are activated simultaneously and extend towards the center. The telescopic devices push the clamping plate closer to the rotor. When the rotor needs to be placed, the telescopic devices retract and cause the clamping plate to release the rotor, so that the moving grasping and placing mechanism can efficiently complete the grasping and placing of the rotor, improving the automation level and working efficiency of the entire rotor grinding device.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0039] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a rotor grinding device, comprising a carrier plate 1, a base plate 3 fixedly connected to the bottom of the carrier plate 1, a rotary motor 4 fixedly connected to the bottom wall of the base plate 3, the output end of the rotary motor 4 passing through the middle of the bottom wall of the base plate 3 and fixedly connected to a drive shaft 5, a driven wheel 6 rotatably connected to the left side of the top wall of the base plate 3, and a driven wheel 7 rotatably connected to the right side of the top wall of the base plate 3, the drive shaft 5 being engaged with driven wheel 6 and driven wheel 7 via a belt, and multiple electric telescopic rods 8 being fixedly connected at equal intervals to the top outer wall of driven wheel 6. Rubber push strips 9 are fixedly connected to the far ends of the telescopic rod 8. Multiple fixed frames 10 are fixedly connected to the left and right sides of the top wall of the carrier plate 1. Brush cylinders 11 are fixedly connected between adjacent fixed frames 10 on the left side. Brush rods 12 are fixedly connected to the top of the driven wheel 7. Fixed cylinders 13 are fixedly connected between adjacent fixed frames 10 on the right side. Multiple hydraulic rods 14 are fixedly connected at equal intervals around the inner wall of the fixed cylinder 13. Rubber push strips 15 are fixedly connected to adjacent ends of the multiple hydraulic rods 14. A movable gripping and placing mechanism 2 is provided on the top of the carrier plate 1.

[0040] Specifically, the rotating motor 4 on the bottom wall of the starter plate 3 drives the drive shaft 5 to rotate. The drive shaft 5 is connected to driven wheel 6 and driven wheel 7 via a belt, thereby driving driven wheel 6 and driven wheel 7 to rotate. For external grinding of the rotor, when driven wheel 6 rotates, multiple electric telescopic rods 8 fixed at equal intervals on its top outer wall rotate accordingly. The length of the electric telescopic rods 8 is adjusted according to the size of the rotor so that the rubber pusher 9 contacts and fixes to the rotor. Multiple fixing brackets 10 on the left side of the top wall of the carrier plate 1 fix the brush cylinder 11. Under the push of the rubber pusher 9, the rotor grinds the brush cylinder 11. The rotor rotates in the cylinder 11, and the components inside the brush cylinder 11 polish the outside of the rotor. On the other side, the driven wheel 7 rotates, driving the brush rod 12 to rotate. The rotor is placed in the fixed cylinder 13 between multiple fixed brackets 10 on the right side of the top wall of the carrier plate 1. Multiple hydraulic rods 14, which are fixed at equal intervals around the inner wall of the fixed cylinder 13, are adjusted according to the rotor size so that the rubber pusher 15 contacts and fixes the rotor. At this time, the rotating brush rod 12 polishes the inside of the rotor. The two can polish the outside and inside of the rotor efficiently, respectively, to meet different processing requirements and improve the quality and efficiency of polishing.

[0041] Reference Figure 1 , Figure 2 and Figure 4 The mobile gripping and placing mechanism 2 includes a top plate 201. A telescopic column 202 is fixedly connected to the middle of the bottom wall of the top plate 201. A fixing ring 203 is fixedly connected to the bottom end of the telescopic column 202. Multiple fixing strips 204 are fixedly connected at equal intervals around the bottom wall of the fixing ring 203. Multiple telescopic devices 205 are fixedly connected to the adjacent side of the multiple fixing strips 204. A clamping plate 206 is fixedly connected to the adjacent end of the multiple telescopic devices 205. A hook 207 is fixedly connected to the bottom end of the adjacent side of the multiple clamping plates 206.

[0042] Specifically, when it is necessary to grasp and place the rotor, the top plate 201 supports the telescopic column 202 to move up and down, adjusting the height of the fixing ring 203. Multiple fixing strips 204 around the bottom wall of the fixing ring 203 serve as fixing plates. When the rotor needs to be grasped, multiple telescopic devices 205 are activated simultaneously and extend towards the center. The telescopic devices 205 push the clamping plate 206 closer to the rotor. The multiple clamping plates 206 clamp the rotor from different directions. The hooks 207 at the bottom of the adjacent side of the clamping plate 206 can further ensure the stability of the rotor during the grasping and moving process. When it is necessary to place the rotor, the telescopic devices 205 retract, causing the clamping plate 206 to release the rotor. At the same time, the telescopic column 202 adjusts its height to accurately place the rotor in the designated position, enabling the mobile grasping and placing mechanism 2 to efficiently complete the task of grasping and placing the rotor, improving the automation level and working efficiency of the entire rotor grinding device.

[0043] Reference Figure 1A control panel 16 is fixedly connected to the front right end of the carrier plate 1, and multiple control buttons 17 are fixedly connected to the top of the control panel 16; a tachometer 18 is fixedly connected to the front left end of the carrier plate 1, and the tachometer 18 is electrically connected to the control panel 16; columns 19 are fixedly connected to the four corners of the bottom wall of the base plate 3, and anti-slip pads 20 are fixedly connected to the bottom of the multiple columns 19.

[0044] Specifically, the control panel 16 is the signal central panel of the entire grinding device. The multiple control buttons 17 on its top control the telescopic column 202, telescopic device 205, rotary motor 4, electric telescopic rod 8, hydraulic rod 14 and tachometer 18 respectively. The tachometer 18 is electrically connected to the control panel 16 and can display the output speed of the rotary motor 4 and the speed of driven wheel 1 6 and driven wheel 2 7 in real time. The column 19 supports the entire device and ensures the stability of the device during operation. The anti-slip pad 20 is used to reduce the vibration generated by the entire equipment during operation.

[0045] Reference Figure 1 and Figure 5 A placement platform 21 is fixedly connected to the middle of the inner bottom wall of the carrier plate 1, and a fixing column 22 is fixedly connected to the middle of the inner bottom wall of the placement platform 21; anti-collision pads 23 are fixedly connected to the four corners on the front side of the carrier plate 1, and the outer walls of the multiple anti-collision pads 23 are all designed with a smooth surface; the multiple anti-slip pads 20 are all designed with a circular shape that is smaller at the top and larger at the bottom, and the bottom walls of the multiple anti-slip pads 20 are all made with a frosted finish.

[0046] Specifically, the placement platform 21 provides a temporary placement area for the rotor during the grinding process, facilitating the loading and unloading of the rotor by the operator. The fixing column 22 in the middle can fix the items placed on the placement platform 21 to a certain extent, preventing them from accidentally slipping. The anti-collision pads 23 are located at the four corners on the front side of the carrier plate 1. Their outer walls are designed with rounded edges to prevent the operator from accidentally bumping into the corners of the carrier plate 1 during operation and thus improving the safety of operation. The anti-slip pads 20 adopt a circular design with a smaller top and a larger bottom and a frosted bottom wall, which increases the friction with the ground and prevents the device from sliding during operation, ensuring the safety and reliability of the grinding process.

[0047] Working principle: The rotating motor 4 on the bottom wall of the start-up base plate 3 drives the drive shaft 5 to rotate. The drive shaft 5 is connected to driven wheel 6 and driven wheel 7 via a belt, thereby driving driven wheel 6 and driven wheel 7 to rotate. For external grinding of the rotor, when driven wheel 6 rotates, multiple electric telescopic rods 8 fixed at equal intervals on its top outer wall rotate accordingly. The length of the electric telescopic rods 8 is adjusted according to the size of the rotor so that the rubber pusher 9 contacts and fixes to the rotor. Multiple fixing brackets 10 on the left side of the top wall of the carrier plate 1 fix the brush cylinder 11. Under the push of the rubber pusher 9, the brush cylinder 11 is also fixed. The rotor rotates in the brush cylinder 11, and the components inside the brush cylinder 11 polish the outside of the rotor. On the other side, the driven wheel 7 rotates, driving the brush rod 12 to rotate. The rotor is placed in the fixed cylinder 13 between multiple fixed brackets 10 on the right side of the top wall of the carrier plate 1. Multiple hydraulic rods 14, which are fixed at equal intervals around the inner wall of the fixed cylinder 13, are adjusted according to the size of the rotor so that the rubber pusher 15 contacts and fixes the rotor. At this time, the rotating brush rod 12 polishes the inside of the rotor. The two can polish the outside and inside of the rotor efficiently, respectively, to meet different processing requirements.

[0048] Furthermore, when it is necessary to grasp and place the rotor, the top plate 201 supports the telescopic column 202 to move up and down, adjusting the height of the fixing ring 203. Multiple fixing strips 204 around the bottom wall of the fixing ring 203 serve as fixing plates. When the rotor needs to be grasped, multiple telescopic devices 205 are activated simultaneously and extend towards the center. The telescopic devices 205 push the clamping plate 206 closer to the rotor. Multiple clamping plates 206 clamp the rotor from different directions. The hooks 207 at the bottom of the adjacent side of the clamping plate 206 can further ensure the stability of the rotor during the grasping and moving process. When it is necessary to place the rotor, the telescopic devices 205 retract, causing the clamping plate 206 to release the rotor. At the same time, the telescopic column 202 adjusts its height to accurately place the rotor in the designated position.
