Description

Technical Field

[0001] This invention relates to the field of deburring technology for the inner bore of motor shafts, specifically a deburring device for the inner bore of motor shafts. Background Technology

[0002] The motor shaft is a crucial component of a motor. As the link between the motor and the equipment for electromechanical energy conversion, it supports rotating parts, transmits torque, and determines the relative position of these parts with respect to the stator. Therefore, the motor shaft must possess reliable strength and rigidity.

[0003] During the machining of existing motor shafts, the internal parts need to be machined, which results in burrs on the inner hole of the motor shaft. At the same time, some debris will remain inside the inner hole of the motor shaft. If the inner hole of the motor shaft is not cleaned and deburred, although it will not affect the motor shaft in the short term, it will reduce the service life of the motor shaft in the long term. The debris inside the motor shaft will also affect the connection between the two ends, which will lead to wear and tear on the connecting parts. Therefore, it is necessary to deburr and clean the inner hole of the motor shaft. Summary of the Invention

[0004] The purpose of this invention is to provide a deburring device for the inner hole of a motor shaft to solve the problems mentioned in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a deburring device for the inner hole of a motor shaft, comprising a deburring device body and a controller. The deburring device body includes a housing, and a clamping component, a polishing component, and a detection component are disposed within the housing. The clamping component is capable of clamping the motor shaft, and the polishing component is capable of polishing the inner hole of the motor shaft. The clamping component and the polishing component cooperate with each other. A water tank is disposed above the housing, and the water tank cooperates with the clamping component. A liquid storage tank and a recovery tank are disposed at the bottom of the housing.

[0006] Furthermore, the clamping assembly includes a limiting lever, a limiting cylinder, and a limiting rod. One end of the limiting lever and the fixed end of the limiting cylinder are respectively connected to the top surface of the box. A clamping plate is installed at the other end of the limiting cylinder. A limiting groove is provided above the box. One end of the limiting rod is installed inside the limiting groove. A clamping plate is also installed on one side of the limiting rod. A water pump is installed at the bottom of the limiting rod. The input end of the water pump is connected to the liquid storage tank. The output end of the water pump cooperates with the clamping plate on the limiting rod.

[0007] Furthermore, the clamping plate includes a limiting plate and an annular frame. One side of the limiting plate is connected to the annular frame, and the other side of the limiting plate is a fixed surface. A blocking block is installed in the middle of the output surface of the limiting plate. One set of blocking blocks of the clamping plate cooperates with the water tank, and another set of blocking blocks of the clamping plate cooperates with the water pump. Multiple sets of clamping cylinders are installed on the annular frame. The clamping cylinders are equidistantly installed outside the annular frame. Multiple sets of arc-shaped clamping plates are provided inside the annular frame, and the output end of the clamping cylinder is connected to the arc-shaped clamping plate.

[0008] Furthermore, the polishing assembly includes two sets of discharge blocks, which are respectively disposed above the sealing block. One set of discharge blocks is in contact with the motor shaft, and the other set of discharge blocks is in contact with the electrolyte. The two sets of discharge blocks are respectively connected to the controller.

[0009] Furthermore, a cleaning assembly is provided inside the housing, which is capable of cleaning the inner hole of the motor shaft. The cleaning assembly includes a bumping assembly and the water tank. The bumping assembly includes a limiting sleeve and a rubber block. A spring is installed inside the limiting sleeve. One end of the spring is connected to the inner top surface of the limiting sleeve, and the other end of the spring is connected to the rubber block. The rubber block is in contact with the motor shaft.

[0010] Furthermore, when the cleaning assembly is in use: the bumping assembly can impact the liquid inside the motor shaft hole, so that the cleaning liquid can clean each thread gap inside the motor shaft hole;

[0011] When the cleaning assembly is in use: the limiting rod will cause the clamping plate to disengage from the motor shaft, and the limiting cylinder will retract, so that the other end of the motor shaft faces into the recycling pool.

[0012] Furthermore, a limiting block is installed at the bottom of the limiting rod, a bearing is installed in the middle of the limiting block, a semi-circular ring is installed at the bottom of the limiting rod, two sets of limiting bearings are installed above the semi-circular ring, the limiting bearings are parallel to the limiting block, and a support rod is installed between the limiting bearings and the limiting block.

[0013] Furthermore, the detection component includes two sets of tension sensing plates. Two sets of tension sensing plates are respectively arranged on the inner side of the semi-circular ring. The two sets of tension sensing plates are parallel to each other. A memory metal wire is installed between the two sets of tension sensing plates, and the memory metal wire is in contact with the motor shaft.

[0014] Furthermore, when the memory metal wire contracts, it can pull two sets of tension sensing plates;

[0015] When the value of the tension sensor plate reaches the threshold, it indicates that the polishing of the inner hole of the motor shaft is complete.

[0016] Furthermore, the controller is installed at the bottom of the enclosure, and a control panel is provided on the enclosure, which is connected to the controller.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. Thus, when the device is in use, it can deburr the inner hole of the motor shaft. At the same time, it can detect the deburring status in real time during the deburring process to prevent over-deburring. It can also clean the debris and residual electrolyte in the inner hole of the motor shaft. Afterwards, the wastewater generated by the cleaning will be recycled to prevent environmental pollution and to recycle resources.

[0019] 2. When in use, the clamping disc of this device can clamp both ends of the motor shaft. Specifically, when one end of the motor shaft is between the limiting plate and the annular frame, the clamping cylinder outside the annular frame will work. When the clamping cylinder works, it can push the arc-shaped clamping plate. When multiple sets of arc-shaped clamping plates approach and clamp the motor shaft at the same time, one end of the motor shaft can be fixed. The sealing block on the clamping disc mainly blocks the inner hole of the motor shaft. Since the two sealing blocks are connected to the water tank and the water pump respectively, they can play different roles. After polishing, the water tank will supply cleaning fluid to the sealing block connected to the water tank, and then supply it to the inside of the motor shaft through the sealing block. During polishing, the water pump will draw electrolyte from the storage tank and inject it into the inner hole of the motor shaft. Thus, the two sets of sealing blocks can play different roles and effects at different times.

[0020] 3. When in use, the cleaning component can clean the inner hole of the polished motor shaft to prevent electrolyte residue. In specific use, the water tank injects cleaning fluid into the inner hole of the motor shaft through the sealing block. However, the cleaning fluid alone cannot effectively clean the inner hole of the motor shaft because the water flow does not completely clean the gaps between the threads when it passes through the threads inside the inner hole of the motor shaft. At this time, the bumping component of the device will impact the motor shaft. When the bumping component is in use, the controller will intermittently energize the spring. When the spring is energized, the spring itself will gradually contract, thereby pulling the rubber block at the other end of the spring. After the controller stops supplying power, the force accumulated by the spring will be released, causing the rubber block to impact the motor shaft. This allows the cleaning fluid inside the motor shaft to slosh inside the inner hole, thereby impacting the gaps between the threads and cleaning the debris remaining in the thread gaps, preventing debris and electrolyte residue from remaining in the inner hole of the motor shaft.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example: Figures 1-10As shown, the present invention provides a deburring device for the inner hole of a motor shaft, comprising a deburring device body 1 and a controller 8. The deburring device body 1 includes a housing 11, and a clamping component 2, a polishing component 3, and a detection component 4 are disposed inside the housing 11. The clamping component 2 can clamp the motor shaft, and the polishing component 3 can polish the inner hole of the motor shaft. The clamping component 2 and the polishing component 3 cooperate with each other. A water tank 61 is disposed above the housing 11, and the water tank 61 cooperates with the clamping component 2. A liquid storage tank 12 and a recovery tank 13 are disposed at the bottom of the housing 11.

[0034] In use, the device clamps the motor shaft using clamping assembly 2, thus fixing its position. Once clamping assembly 2 has fixed the motor shaft, polishing assembly 3 polishes the inner hole of the motor shaft without damaging the internal threads, removing burrs. When the device performs electrolytic polishing, detection assembly 4 monitors the electrolysis process in real time to prevent over-electrolysis that could damage the internal threads of the motor shaft. After polishing, water tank 61 injects cleaning liquid into the inner hole of the motor shaft to clean it and prevent further damage. While cleaning, the clamping plate 5 on the limiting rod 23 disengages from the motor shaft, and the limiting cylinder 22 retracts, causing the clamping plate 5 under the limiting cylinder 22 to move upwards. This causes the motor shaft to change its angle, and after the angle changes, the motor shaft will face the recycling tank 13. When cleaning the inner hole of the motor shaft, the wastewater generated after cleaning will be recycled by the recycling tank 13 for reuse, reducing resource consumption. Therefore, when using this device, it can not only deburr the inner hole of the motor shaft, but also does not affect the shape of the thread during the deburring process, so that the motor shaft can be used normally, while also reducing resource waste.

[0035] like Figures 1-2 , Figures 4-6 and Figure 8 As shown in this embodiment, specifically, the clamping assembly 2 includes a limiting lever 21, a limiting cylinder 22, and a limiting rod 23. One end of the limiting lever 21 and the fixed end of the limiting cylinder 22 are respectively connected to the inner top surface of the housing 11. A clamping plate 5 is installed on the other end of the limiting cylinder. A limiting groove is provided on the top of the housing 11. One end of the limiting rod 23 is installed inside the limiting groove. A clamping plate 5 is also installed on one side of the limiting rod 23. A water pump is installed at the bottom of the limiting rod 23. The input end of the water pump is connected to the liquid storage tank 12. The output end of the water pump cooperates with the clamping plate 5 on the limiting rod 23.

[0036] When in use, the clamping component 2 of the device can clamp the motor shaft, limiting its position and preventing displacement or leakage during deburring. In practice, the operator first installs the motor shaft onto the limiting rod 21, then connects it to the clamping plate 5 on the limiting cylinder 22. Because the sealing block 53 cooperates with the inner hole of the motor shaft, leakage from the gaps in the inner hole is prevented. Then, the other end of the motor shaft is connected to the clamping plate 5 on the limiting rod 23, thus completely limiting the motor shaft. The water pump then draws electrolyte from the storage tank 12 and injects it into the inner hole of the motor shaft. Once a certain amount of electrolyte is stored in the motor shaft, the polishing component 3 of the device operates to deburr the inner hole of the motor shaft. After polishing, the water tank 61 injects cleaning liquid into the inner hole of the motor shaft to clean it and prevent residual electrolyte from corroding the inner hole.

[0037] like Figures 5-6 As shown, in this embodiment, specifically, the clamping plate 5 includes a limiting plate 51 and an annular frame 52. One side of the limiting plate 51 is connected to the annular frame 52, and the other side of the limiting plate 51 is a fixed surface. A blocking block 53 is installed in the middle of the output surface of the limiting plate 51. One set of blocking blocks 53 of the clamping plate 5 cooperates with the water tank 61, and another set of blocking blocks 53 of the clamping plate 5 cooperates with the water pump. Multiple sets of clamping cylinders 54 are installed on the annular frame 52. The clamping cylinders 54 are equidistantly installed on the outside of the annular frame 52. Multiple sets of arc-shaped clamping plates 55 are provided on the inner side of the annular frame 52. The output end of the clamping cylinder 54 is connected to the arc-shaped clamping plate 55.

[0038] When in use, the clamping disc 5 of this device can clamp both ends of the motor shaft. Specifically, when one end of the motor shaft is between the limiting plate 51 and the annular frame 52, the clamping cylinder 54 outside the annular frame 52 will operate. When the clamping cylinder 54 operates, it can push the arc-shaped clamping plate 55. When multiple sets of arc-shaped clamping plates 55 simultaneously approach and clamp the motor shaft, one end of the motor shaft can be fixed. The sealing block 53 on the clamping disc 5 mainly blocks the inner hole of the motor shaft. Because the two sealing blocks 53 are connected to the water tank 61 and the water pump respectively, they can achieve different effects. After polishing, the water tank 61 supplies cleaning fluid to the sealing block 53 connected to the water tank 61, and then supplies it to the inside of the motor shaft through the sealing block 53. During polishing, the water pump draws electrolyte from the storage tank 12 and injects it into the inner hole of the motor shaft. Thus, the two sets of sealing blocks 53 can play different roles and have different effects at different times.

[0039] like Figures 5-6As shown, in this embodiment, specifically, the polishing component 3 includes two sets of discharge blocks 31. The two sets of discharge blocks 31 are respectively disposed above the sealing block 53. One set of discharge blocks 31 is in contact with the motor shaft, and the other set of discharge blocks 31 is in contact with the electrolyte. The two sets of discharge blocks 31 are respectively connected to the controller 8.

[0040] When in use, the polishing component 3 of this device can remove burrs from the inner hole of the motor shaft. Specifically, the polishing component 3 is equipped with two sets of discharge blocks 31, which are installed on two different sealing blocks 53 at different positions. One set of discharge blocks 31 is installed in contact with the motor shaft, while the other set of discharge blocks 31 is in contact with the electrolyte. Thus, during use, one set of discharge blocks 31 supplies power to the motor shaft, while the other set of discharge blocks 31 supplies power to the electrolyte, thereby achieving electrolytic polishing. In conjunction with the detection component 4 of the device, it can ensure that the electrolytic polishing does not become excessive.

[0041] like Figures 1-2 and Figure 7 As shown in this embodiment, specifically, a cleaning component 6 is provided inside the housing 11. The cleaning component 6 can clean the inner hole of the motor shaft. The cleaning component 6 includes a bumping component 7 and the water tank 61. The bumping component 7 includes a limiting sleeve 71 and a rubber block 72. A spring 73 is installed inside the limiting sleeve 71. One end of the spring 73 is connected to the inner top surface of the limiting sleeve 71, and the other end of the spring 73 is connected to the rubber block 72. The rubber block 72 is in contact with the motor shaft.

[0042] When in use, the cleaning component 6 of this device can clean the inner hole of the polished motor shaft to prevent electrolyte residue. Specifically, the water tank 61 injects cleaning fluid into the inner hole of the motor shaft through the sealing block 53. However, the cleaning fluid alone cannot effectively clean the inner hole of the motor shaft because the water flow does not completely clean the gaps between the threads when it passes through the threads inside the inner hole of the motor shaft. At this time, the bumping component 7 of the device will impact the motor shaft. When the bumping component 7 is in use, the controller 8 will intermittently energize the spring 73. When the spring 73 is energized, the spring 73 will gradually contract, thereby pulling the rubber block 72 at the other end of the spring 73. After the controller 8 stops supplying power, the force accumulated in the spring 73 will be released, causing the rubber block 72 to impact the motor shaft. This allows the cleaning fluid inside the motor shaft to slosh inside the inner hole, impacting the gaps between the threads and cleaning the debris remaining in the thread gaps, preventing debris and electrolyte residue from remaining in the inner hole of the motor shaft.

[0043] like Figure 2 , Figure 9 and Figure 10As shown in this embodiment, specifically, when the cleaning component 6 is used: the bumping component 7 can impact the liquid inside the motor shaft hole, so that the cleaning liquid can clean each thread gap inside the motor shaft hole.

[0044] When the cleaning component 6 is in use: the limiting rod 23 will cause the clamping plate 5 to disengage from the motor shaft, and the limiting cylinder 22 will retract, so that the other end of the motor shaft faces into the recycling pool 13;

[0045] Because a single water flow cannot effectively clean the inner hole of the motor shaft, the device's bumping component 7 is required to impact the motor shaft to improve cleaning efficiency. After impacting the motor shaft, the water flow inside the motor shaft will violently shake inside the inner hole of the motor shaft, and the impact force can also clean the debris remaining in the thread gap.

[0046] While cleaning the motor shaft, one end of the motor shaft outlet will face the recycling tank 13, so that the wastewater generated during cleaning can be recycled through the recycling tank 13, which can not only avoid impacting the environment, but also make rational use of resources.

[0047] like Figure 4 and Figure 8 As shown in this embodiment, specifically, a limiting block 211 is installed at the bottom of the limiting rod 21, a bearing is installed in the middle of the limiting block 211, a semi-circular ring 212 is installed at the bottom of the limiting rod 21, two sets of limiting bearings 213 are installed above the semi-circular ring 212, the limiting bearings 213 are parallel to the limiting block 211, and a support rod is installed between the limiting bearings 213 and the limiting block 211;

[0048] When the limiting lever 21 of the device limits the motor shaft, it can limit the motor shaft through the semi-circular ring 212. Since the semi-circular ring 212 is limited to the bottom of the limiting lever 21 by the support rod, and the support rod does not completely limit the state of the semi-circular ring 212, it can adjust the current angle on its own according to the needs of the clamping component 2 to prevent the semi-circular ring 212 from disengaging from the motor shaft.

[0049] like Figure 8 As shown, in this embodiment, specifically, the detection component 4 includes two sets of tension sensing plates 41. Two sets of tension sensing plates 41 are respectively arranged on the inner side of the semi-circular ring 212. The two sets of tension sensing plates 41 are parallel to each other. A memory metal wire 42 is installed between the two sets of tension sensing plates 41. The memory metal wire 42 is in contact with the motor shaft.

[0050] The detection component 4 of the device can detect the progress of electropolishing during use, preventing over-polishing. In specific use, because the motor shaft is installed inside the semi-circular ring 212, the memory metal wire 42 will come into contact with the motor shaft. Thus, the memory metal wire 42 can better absorb the heat released by the motor shaft. During electropolishing, the motor shaft itself will generate a certain amount of heat. When the memory metal wire 42 is heated, it will contract. Since the two ends of the memory metal wire 42 are connected to the tension sensing plates 41 respectively, the two tension sensing plates 41 will obtain values ​​when it contracts, thereby judging the current progress of electropolishing and preventing over-polishing.

[0051] like Figure 8 As shown, in this embodiment, specifically, when the memory metal wire 42 contracts, it can pull two sets of tension sensing plates 41;

[0052] When the value of tension sensor plate 41 reaches the threshold, it indicates that the polishing of the inner hole of the motor shaft is complete.

[0053] Because the motor shaft itself generates a certain amount of heat during electropolishing, and when the memory metal wire 42 is heated, it will contract. Since the two ends of the memory metal wire 42 are connected to the tension sensing plates 41 respectively, the two tension sensing plates 41 will obtain a value when it contracts. When the value reaches the threshold, it means that the current electropolishing is completed. Continuing electropolishing will affect the inner hole of the motor shaft, thus reminding the controller to stop electropolishing. If electropolishing is not stopped after 5 seconds beyond the threshold, the controller 8 will automatically disconnect the electropolishing.

[0054] like Figures 1-3 As shown, in this embodiment, specifically, the controller 8 is installed at the bottom of the housing 11, and a control panel is provided on the housing 11, which is connected to the controller 8;

[0055] When in use, the deburring device body 1 can be operated and monitored through the controller 8, and the equipment value control panel on the housing 11 is connected to the controller 8, so the operator can control the deburring device body 1 through the control panel.

[0056] Working Principle: During use, the clamping component 2 clamps the motor shaft, thus fixing its position. Once the clamping component 2 has secured the motor shaft, the polishing component 3 polishes the inner hole of the motor shaft without damaging the internal threads, removing burrs. When the device performs electrolytic polishing, the detection component 4 monitors the electrolysis process in real time to prevent over-electrolysis that could damage the internal threads of the motor shaft. After polishing is complete, the water tank 61 injects cleaning liquid into the inner hole of the motor shaft to clean it. To prevent residual electrolyte, during cleaning, the clamping plate 5 on the limiting rod 23 disengages from the motor shaft, and the limiting cylinder 22 retracts, causing the clamping plate 5 under the limiting cylinder 22 to move upwards. This causes the motor shaft to change its angle, and after the angle changes, the motor shaft will face the recycling tank 13. When cleaning the inner hole of the motor shaft, the wastewater generated after cleaning will be recycled by the recycling tank 13 for reuse, reducing resource consumption. Therefore, when using this device, it can not only deburr the inner hole of the motor shaft, but also does not affect the shape of the threads during the deburring process, so that the motor shaft can be used normally, while also reducing resource waste.

[0057] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
