Description

Technical Field

[0001] The present invention relates to the technical field of motor shaft processing, and particularly to a motor shaft polishing device capable of detecting polishing accuracy. Background Art

[0002] The smoothness of the motor shaft is an important indicator determining the operation of the motor. After the motor shaft is processed, its surface needs to be polished to ensure the smoothness of the motor shaft surface.

[0003] Currently, an automatic polishing machine is usually used for grinding and polishing. However, during the use of the existing polishing machines, most of their grinding components are two groups or more, and these grinding components mostly operate synchronously. Either they contact the motor shaft simultaneously for grinding and polishing, or they separate from the motor shaft simultaneously to stop grinding and polishing. When performing work with relatively low grinding accuracy, there will be a situation of excessive energy efficiency. Moreover, most of the water spraying components are controlled by electrical signals, and it is difficult to troubleshoot if there are faults in the wires or sensors.

[0004] For example, a fully automatic polishing machine for motor shafts disclosed in a Chinese patent, with the publication number CN106808349B, will have a situation of excessive energy efficiency when multiple groups of grinding components perform synchronous polishing operations for work with relatively low grinding accuracy. For example, in a grinding and polishing machine for motor shafts disclosed in a Chinese patent, with the publication number CN216577151U, there is a problem that when spraying water at the polishing area, electrical signal control is adopted, and it is difficult to troubleshoot if there are faults in the wires or sensors.

The motor II is controlled to start by the control panel to drive the motor shaft to rotate. Then the motor I is controlled to start by the control panel to drive the rotating shaft to rotate, so that the support base can move linearly along the guide rod II driven by the motor I, so that the polishing component on the support base can move along the guide rod II, so as to polish the motor shaft. The auxiliary component assists the polishing operation, making it more convenient to disassemble and assemble the motor shaft. At the same time, during the process of opening the lid, since the lid drives components such as the guide rod I and the fixed seat to flip synchronously, the magnet I and the magnet II are separated, so that the polishing component cannot move along the guide rod II, avoiding accidental injury to the operator by the polishing component during the installation of the motor shaft and improving safety.

The support base provides a supporting force for the housing, the housing provides a supporting force for the winding motor, and the control panel controls the start of the winding motor, so that a section of abrasive paper exposed outside the housing polishes the motor shaft. The pressing rod reduces the bending range of the abrasive paper, always keeps it close to the motor shaft to avoid deterioration of the polishing effect. The control panel controls the start of the first electric push rod, so that the corresponding polishing assembly moves. According to the accuracy requirements of polishing, the number of abrasive papers of the polishing assemblies in contact with the motor shaft can be selected as needed, which is more energy-saving and environmentally friendly.

[0022] (3) The motor shaft polishing device capable of detecting polishing accuracy is provided with a water tank, a water pump, a water inlet pipe, a water outlet pipe, a water storage box, a fixing plug, a second spring, a third guiding rod, a third sliding rod, a sliding plate, a supporting plate, a fourth sliding rod, a water delivery pipe, and a spray head. When the corresponding polishing assembly polishes the motor shaft, the corresponding water spraying assembly also operates simultaneously. Water is sprayed out through the spray head to cool the contact area between the abrasive paper and the motor shaft, and at the same time, to reduce dust of the debris of the abrasive paper, avoiding the debris flying everywhere. It can automatically start the corresponding number of spray heads according to the number of polishing assemblies enabled, and can select the number of groups of water spraying assemblies to start according to the polishing requirements, which is more energy-saving and environmentally friendly.

Detailed implementation manners

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0038] Please refer to Figures 1 - 12 , the present invention provides the following technical solutions:

[0039] Embodiment 1: A motor shaft polishing device capable of detecting polishing accuracy, comprising a housing 1, a control panel, a lid 11 hinged to the top of the housing 1 by a hinge, and a polishing assembly movably installed in the housing 1. A second motor 61 is fixedly installed on the side wall of the housing 1 through a motor box. One end of the output shaft of the second motor 61 is detachably connected to a motor shaft 6 through a coupling. The polishing assembly includes: a first motor 12, a rotating shaft 13, a gear 14, a rack 15, a fixed seat 16, a fixed rod 17, a first guide rod 18, a first magnet 19, a second magnet 110, a support seat 2, and a second guide rod 21. A second guide rod is slidably penetrated through the support seat 2, and both ends of the second guide rod 21 are fixedly installed on the inner walls of both sides of the housing 1. The inner walls of both sides of the lid 11 are respectively fixedly connected to both ends of the rack 15. A gear 14 is engaged with the rack 15. A rotating shaft 13 is fixedly installed on the side wall of the gear 14. One end of the rotating shaft 13 is fixedly installed on the output end of the first motor 12 through a coupling. The outer wall of the first motor 12 is fixedly installed on the top of the fixed seat 16 through a motor box. A fixed rod 17 is fixedly installed at the bottom of the fixed seat 16. A first guide rod 18 is slidably penetrated through the fixed rod 17. Both ends of the first guide rod 18 are respectively fixedly connected to the inner walls of both sides of the lid 11. A first magnet 19 is fixedly installed at one end of the fixed rod 17. The bottom of the first magnet 19 is magnetically connected to the top of the second magnet 110. The side wall of the second magnet 110 is fixedly installed on the support seat 2.

[0040] During use, by opening the lid 11, the motor shaft 6 to be polished is installed in the housing 1, and then the lid 11 is closed, so that the first magnet 19 and the second magnet 110 are adsorbed together. The second motor 61 is controlled to start through the control panel to drive the motor shaft 6 to rotate. Then, the first motor 12 is controlled to start through the control panel to drive the rotating shaft 13 to rotate. The rotating shaft 13 drives the gear 14 to rotate. The gear 14 is engaged with the rack 15. The fixed rod 17 provides a supporting force for the fixed seat 16, and the fixed seat 16 provides a supporting force for the first motor 12. Through the sliding fit between the fixed rod 17 and the first guide rod 18, after the first motor 12 is started, the fixed rod 17 can be driven to move linearly along the first guide rod 18. The fixed rod 17 drives the first magnet 19 to move, the first magnet 19 drives the second magnet 110 to move, and the second magnet 110 drives the support seat 2 to move. The support seat 2 and the second guide rod 21 are slidably fitted, so that the support seat 2 can move linearly along the second guide rod 21 under the drive of the first motor 12, so that the polishing assembly on the support seat 2 can move along the second guide rod 21, thereby polishing the motor shaft 6.

[0041] Embodiment 2. The technical solution of this embodiment different from that of Embodiment 1 is as follows: An electric push rod 128 is fixedly installed on the support base 2. One end of the electric push rod 128 is fixedly connected to the side wall of the extrusion rod 29. The extrusion rod 29 is arranged in an L shape. At the L-shaped intersection of the extrusion rod 29 and the end horizontal to the top of the support base 2, it is inclined. The inclined end of the extrusion rod 29 slidably abuts against a sliding rod 1210 also arranged in an inclined manner. The other end of the sliding rod 1210 is fixedly connected to the side wall of the sliding rod 211. The side wall of the sliding rod 211 is fixedly connected to one end of a spring 1212. The other end of the spring 1212 is fixedly installed on the inner wall of one side of the support base 2. The bottom of the sliding rod 211 is fixedly connected to the top of the outer shell 22. A winding motor 23 is fixedly installed on the side wall of the outer shell 22 through a motor box. A winding disc 24 is detachably and fixedly connected to the output end of the winding motor 23. One end of a sandpaper 25 is fixedly connected to the side wall of the winding disc 24. The other end of the sandpaper 25 is fixedly installed on the unwinding disc 26. The sandpaper 25 is slidably wound around the winding disc 24 and the unwinding disc 26. The unwinding disc 26 is detachably and movably installed on the inner wall of one side of the outer shell 22 through a mounting shaft. The outer shell 22 is arranged in a clamp shape. A pressing rod 27 is fixedly installed on the outer wall at the opening of the outer shell 22. The side wall of the pressing rod 27 slidably abuts against the sandpaper 25.

[0042] During use, the support base 2 provides a supporting force for the outer shell 22 through the sliding rod 211, provides a supporting force for the winding motor 23 through the outer shell 22. The winding motor 23 is controlled to start through the control panel. The winding motor 23 drives the winding disc 24 to rotate, so that the sandpaper 25 is released from the unwinding disc 26 and wound on the winding disc 24. The motor shaft 6 is polished by a section of the sandpaper 25 exposed outside the outer shell 22. After the sandpaper 25 abuts tightly against the motor shaft 6, it bends towards the side where the winding motor 23 is located. By arranging the pressing rods 27 on the upper and lower sides of the outer shell 22, the pressing rods 27 press the sandpaper 25 tightly.

[0043] The electric push rod 128 is controlled to start through the control panel. The electric push rod 128 drives the extrusion rod 29 to move. The extrusion rod 29 squeezes the sliding rod 1210 to move. The sliding rod 1210 drives the sliding rod 211 to move. Through the sliding fit between the sliding rod 211 and the support base 2, the sliding rod 211 can move linearly along the support base 2 under the action of the electric push rod 128, so that the corresponding polishing assembly moves.

[0044] When the extrusion rod 29 is separated from the sliding rod 1210, the spring 1212 can provide an elastic force for the sliding rod 211, so that this group of polishing assemblies move away from the side where the motor shaft 6 is located, thus stopping the polishing operation.

[0045] Embodiment 3. The technical solution of this embodiment that is different from Embodiment 2 is that a water spraying assembly for cooling the grinding and polishing area is provided inside the housing 1. The water spraying assembly includes: a water tank 3, a water pump 31, a water inlet pipe 32, a water outlet pipe 33, a water storage box 34, a fixing plug 35, a second spring 36, a guide rod 37, a sliding rod 38, a sliding plate 39, a support plate 310, a sliding rod 311, a water delivery pipe 312, and a spray head 313. A water tank 3 is fixedly installed at the top of the support base 2. A water pump 31 is fixedly installed at the top of the water tank 3. The water inlet end of the water pump 31 is communicated with the water tank 3 through the water inlet pipe 32. The water outlet end of the water pump 31 is communicated with the water storage box 34 through the water outlet pipe 33. The side wall of the water storage box 34 is fixedly installed on the side wall of the support base 2 for adjusting the water output. A through hole is provided in the water storage box 34;

[0046] The number of the through hole, the fixing plug 35, the second spring 36, the guide rod 37, the sliding rod 38, the sliding plate 39, the support plate 310, the sliding rod 311, the water delivery pipe 312, and the spray head 313 is two groups. One through hole, the fixing plug 35, the second spring 36, the guide rod 37, the sliding rod 38, the sliding plate 39, the support plate 310, the sliding rod 311, the water delivery pipe 312, and the spray head 313 is a group. The connection methods between the parts within the same group are as follows:

[0047] One end of the second spring 36 is fixedly connected to the inner side wall of the water storage box 34. The other end of the second spring 36 is fixedly connected to the side wall of the fixing plug 35. The size of the fixing plug 35 matches the through hole for adjusting the water output. The two inner side walls of the water storage box 34 are correspondingly fixedly connected to both ends of the guide rod 37. The guide rod 37 slidably penetrates through the fixing plug 35. A sliding rod 38 is fixedly installed on the fixing plug 35. The sliding rod 38 slidably penetrates through the water storage box 34. The inner wall of the sliding rod 38 in contact with the water storage box 34 is sealed. One end of the sliding rod 38 slidably abuts against a sliding plate 39. One end of the side wall of the sliding plate 39 is fixedly connected to one end of a movable shaft. The other end of the movable shaft is hingedly installed on the side wall of the support plate 310 through a torsion spring. The side wall of the support plate 310 is fixedly installed on the side wall of the water storage box 34. A water delivery pipe 312 is fixedly installed at the through hole of the water storage box 34. The other end of the water delivery pipe 312 is fixedly installed with a spray head 313. A sliding rod 311 is fixedly installed on the outer shell 22. One end of the sliding rod 311 slidably abuts against the side wall of the sliding plate 39.

[0048] During use, when the corresponding grinding assembly performs grinding and polishing operations on the motor shaft 6, the corresponding water spraying assembly also operates simultaneously;

[0049] The support base 2 provides a supporting force for the water tank 3. The water pump 31 is started through the control panel. The water pump 31 conveys the water in the water tank 3 to the water storage box 34 through the water inlet pipe 32 and the water outlet pipe 33. Correspondingly, when the outer shell 22 moves towards the side where the motor shaft 6 is located under the action of the extrusion rod 29, the outer shell 22 drives the fourth sliding rod 311 to move, and the fourth sliding rod 311 drives the sliding plate 39 to move. The support plate 310 provides a supporting force for the movable shaft, and the movable shaft provides a supporting force for the sliding plate 39, enabling the sliding plate 39 to flip around the movable shaft under the extrusion of the fourth sliding rod 311. The sliding plate 39 squeezes the third sliding rod 38 to move, and the third sliding rod 38 drives the fixed plug 35 to move away from the side where the sliding plate 39 is located. Through the sliding fit between the fixed plug 35 and the third guide rod 37, the fixed plug 35 can move linearly along the third guide rod 37. The fixed plug 35 moves out of the through hole. At this time, the water in the water storage box 34 flows through the through hole and the water delivery pipe 312 and finally sprays from the nozzle 313 to the contact position between the motor shaft 6 and the abrasive paper 25;

[0050] When it is not necessary for multiple grinding assemblies to operate simultaneously, as the first electric push rod 28 shortens, the corresponding outer shell 22 resets under the action of the first spring 212, and the sliding plate 39 no longer exerts a force on the third sliding rod 38, enabling the corresponding fixed plug 35 to block the corresponding through hole again under the action of the second spring 36.

[0051] Embodiment 4. The technical solution that differentiates this embodiment from Embodiment 3 is that a fixing plate 4 is fixedly installed on the side wall of the support base 2, and a micro spectrometer 41 for detecting the polishing accuracy is fixedly installed at the bottom of the fixing plate 4. The model of the micro spectrometer 41 is Hamamatsu C12880MA;

[0052] A water wiping assembly for removing water droplets is arranged in the housing 1. The water wiping assembly includes: a second electric push rod 5, a first support rod 51, a second support rod 52, a sponge block 53, a first slider 54, a second slider 541, a first sliding plate 55, a second sliding plate 56, a fourth guide rod 57, a third spring 58, a third magnet 59, a fourth magnet 510, a mounting plate 511, and bristles 512. One end of the second electric push rod 5 is fixedly connected to the side wall of the support base 2, and the other end of the second electric push rod 5 is fixedly installed with a first support rod 51. One end of the first support rod 51 is fixedly installed with a second support rod 52, and the side wall of the sponge block 53 is fixedly installed on the second support rod 52;

[0053] There are two sets of slider one 54 and slider two 541. One ends of the two sets of slider one 54 are respectively fixedly installed on the side walls of slide plate one 55 and slide plate two 56. One ends of the two sets of slider two 541 are respectively installed on the side walls of the two outer shells 22. A guide rod four 57 is fixedly installed on the support base 2. A spring three 58 is fixedly installed at the top of the guide rod four 57. The other end of the spring three 58 is fixedly installed with a slide plate one 55. A slide plate two 56 is slidably installed on the side wall of the slide plate one 55. A slider two 541 is slidably abutted against the side wall of the slider one 54. Both inner walls of the slide plate one 55 are fixedly connected to both ends of a magnet three 59. A magnet four 510 is magnetically connected to the bottom of the magnet three 59. An installation plate 511 is fixedly installed at the bottom of the magnet four 510. A group of bristles 512 are fixedly installed at the bottom of the installation plate 511.

[0054] During use, the support base 2 provides a supporting force for the electric push rod two 5, the support base 2 provides a supporting force for the fixing plate 4, the fixing plate 4 provides a supporting force for the micro spectrometer 41. The electric push rod two 5 is controlled by the control panel to drive the support rod one 51 to move, the support rod one 51 drives the support rod two 52 to move, the support rod two 52 drives the sponge block 53 to move, so that the sponge block 53 contacts the motor shaft 6, thereby drying the water on the surface of the motor shaft 6. The dried motor shaft 6 is detected by the micro spectrometer 41 to evaluate the polishing quality.

[0055] When the outer shell 22 closest to the sponge block 53 moves towards the side where the motor shaft 6 is located, the outer shell 22 drives the slider two 541 to move, the slider two 541 squeezes the slider one 54 to move, so that the slider one 54 drives the slide plate one 55 to move upward, so that the slide plate one 55 shields the water droplets splashed on the motor shaft 6 due to the rotation of the motor shaft 6 by the nozzle 313.

[0056] The side wall of the outer shell 22 closest to the sponge block 53 provides a supporting force for the guide rod four 57. The guide rod four 57 is slidably matched with the slide plate one 55. The spring three 58 provides a downward elastic force for the slide plate one 55, so that when the outer shell 22 moves away from the side where the motor shaft 6 is located, the slide plate one 55 can return to the initial state under the action of the spring three 58.

[0057] The slide plate one 55 provides a supporting force for the magnet three 59. The magnet three 59 and the magnet four 510 are adsorbed together. The magnet four 510 provides a supporting force for the installation plate 511. The installation plate 511 provides a supporting force for the bristles 512. The bristles 512 brush the water vapor attached to the surface of the motor shaft 6.

[0058] When it is necessary to improve the polishing accuracy and make the outer shell 22 farther away from the sponge block 53 move towards the side where the motor shaft 6 is located, the outer shell 22 drives another group of slider two 541 to move, and the slider two 541 squeezes another group of slider one 54 to move, so that the slider one 54 drives the slide plate two 56 to move upward.

[0059] In another embodiment, the polishing operation is assisted by an auxiliary component, so that when the lid 11 is opened, it can rotate to loosen one end of the motor shaft 6, and after the lid 11 is closed, it can tighten one end of the motor shaft 6, so that when installing the motor shaft 6 for the polishing operation to be performed, only one end needs to be fixed, and the other end can be automatically fixed, and fixing both ends at the same time is more secure.

[0060] In another embodiment, the second support rod 52 is slidably sleeved on one end of the first support rod 51, and the second support rod 52 and the first support rod 51 are fixed by bolts or detachable components, which is convenient for replacing the wet sponge block 53.
