[0002] The pump shaft is one of the core components of the pump. Its main function is to transmit the power of the motor to the impeller, thereby generating water flow power. The pump shaft fixes the impeller through a key, connects to the motor shaft through a coupling, and is supported on bearings. The commonly used material is carbon steel. The design of the pump shaft needs to comprehensively consider factors such as the overall layout of the water pump, the magnitude of the force, the position of the parts on the shaft, and the fixing method.

[0003] When the existing pump shaft grinding device grinds multiple pump shafts simultaneously, generally all the pump shafts are fixed on the same horizontal plane, and then the grinding device grinds multiple pump shafts simultaneously to improve the grinding efficiency. However, since there are certain differences in the diameter and surface roughness of each pump shaft, the grinding speed of the outer wall of each pump shaft is different during grinding, resulting in a certain accuracy difference for each pump shaft after grinding, and secondary finishing is required, which is a cumbersome process and affects the production efficiency.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. The pressure mechanism can push multiple grinding mechanisms to contact the shaft body with the same extrusion force at the same time, so as to ensure that the grinding force received by each water pump shaft body during grinding is equal. And the driving mechanism is started, and the driving mechanism drives all the rotating shafts to rotate at the same speed, so that the grinding speed of each water pump shaft is the same, and further ensures that each water pump shaft body is ground with the same grinding efficiency, reducing the error precision during the grinding of each water pump shaft body.

[0022] 2. When the grinding speed of an individual water pump shaft body is slow, the adjustment mechanism at its bottom is started to rise in height at this time, so that the grinding speed of this water pump shaft is increased, thereby reducing the error precision during the grinding of each water pump shaft body. And under the push of the adjustment mechanism at the bottom of this water pump shaft body, the adjustment mechanism at the bottom and the two grinding plates above it form a triangular limit for this water pump shaft body, increasing the grinding efficiency of this water pump shaft body while improving the stability during the grinding of this water pump shaft body.

[0023] 3. During the grinding process, when the shaft body of the water pump shaft passes through the water tank, first, a surface cleaning mechanism removes the debris on the shaft body of the water pump shaft, and then an adjustment mechanism sprays and cools the shaft body to prevent the temperature of the shaft body of the water pump shaft from being too high. After that, another surface cleaning mechanism scrapes off the water stains on the shaft body of the water pump shaft, thus preventing water splashing when the shaft body of the water pump shaft rotates and realizing the recycling of cooling water at the same time. When the adjustment mechanism grinds the shaft body of the water pump shaft, one of the rollers can clean the debris on the shaft body of the water pump shaft before the adjustment mechanism grinds, and after the adjustment mechanism grinds, the other roller can clean the debris ground by the adjustment mechanism.

[0024] 4. Due to the different roughness of the shaft body of the water pump shaft, the wear degrees of each grinding plate may be different, which may affect the consistency of the grinding efficiency of each shaft body of the water pump shaft. At this time, the control system can control the second electric drive rod on the side of the water pump shaft with a slower grinding speed to extend or contract. At this time, the second electric drive rod drives the grinding plates on both sides of the shaft body of the water pump shaft to move along the tangent direction of the contact position with the shaft body of the water pump shaft, so that the unworn area of the grinding plate contacts the shaft body of the water pump shaft, thereby improving the grinding efficiency of the water pump shaft.

[0034] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0035] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.

[0036] As Figures 1-8 shown, a device for grinding the shaft body of a directional water pump shaft provided by the present invention includes a workbench 1. A plurality of fixed frames 11 are arranged side by side on the upper end surface of the workbench 1. Each fixed frame 11 is rotatably connected to a rotating shaft 12. The rotating shafts 12 are fixedly connected to a driving mechanism 3 for clamping and fixing the shaft body. A driving mechanism 3 for driving them to rotate synchronously is commonly connected between all the rotating shafts 12;

[0037] A support frame 13 is fixedly connected to the upper end surface of the workbench 1. The support frame 13 is fixedly connected to a first electric lifting seat 14. The first electric lifting seat 14 is fixedly connected to a pressure mechanism 4. The pressure mechanism 4 is connected to a plurality of grinding mechanisms 5. The pressure mechanism 4 can push a plurality of grinding mechanisms 5 to contact the shaft body simultaneously with the same extrusion force, and the grinding mechanism 5 can grind the shaft body;

[0038] A second electric lifting seat 15 is fixedly connected to the upper end surface of the workbench 1. The second electric lifting seat 15 is fixedly connected to a mounting seat 16. A plurality of water tanks 9 are slidably connected to the mounting seat 16 in parallel in the vertical direction. A regulating bolt 10 is threadedly connected between each water tank 9 and the mounting seat 16. Two surface cleaning mechanisms 6 are arranged in each water tank 9. The two surface cleaning mechanisms 6 can jointly clean the surface of the shaft body. The two surface cleaning mechanisms 6 are jointly connected to a power assembly 8 that drives them to rotate synchronously. An adjustment mechanism 7 is arranged between the two surface cleaning mechanisms 6. The adjustment mechanism 7 can spray and cool the shaft body, and the adjustment mechanism 7 can polish the shaft body;

[0039] A control system that can synchronously control the grinding speed and grinding accuracy of the shafts of all water pumps by controlling the clamping mechanism 2, the grinding mechanism 5, the surface cleaning mechanism 6, and the adjustment mechanism 7.

[0040] In this embodiment, the shaft bodies of each water pump shaft are fixed by the respective clamping mechanisms 2. The first electric lifting seat 14 is started to drive the pressure mechanism 4 to move downward. At this time, each grinding mechanism 5 contacts the shaft body of each water pump shaft. At this time, the pressure mechanism 4 can push a plurality of grinding mechanisms 5 to contact the shaft body with the same extrusion force at the same time, so as to ensure that the grinding forces received by the shaft bodies of each water pump shaft during grinding are equal. And the driving mechanism 3 is started. The driving mechanism 3 drives all the rotating shafts 12 to rotate at the same speed, so that the grinding speeds of each water pump shaft are the same, and further ensures that the shaft bodies of each water pump shaft are ground with the same grinding efficiency, reducing the error precision during the grinding of the shaft bodies of each water pump shaft;

[0041] Further, before grinding, the second electric lifting seat 15 is started to extend. The second electric lifting seat 15 drives all the water tanks 9 to move upward through the mounting seat 16. The two surface cleaning mechanisms 6 in each water tank 9 can contact the shaft body of a water pump shaft. During the grinding process, when the shaft body of the water pump shaft passes through the water tank 9, first, a surface cleaning mechanism 6 removes the debris on the shaft body of the water pump shaft, and then the adjustment mechanism 7 performs a spray cooling treatment on the shaft body to avoid the temperature of the shaft body of the water pump being too high. Then, the other surface cleaning mechanism 6 scrapes off the water stains on the shaft body of the water pump shaft, thus avoiding water splashing when the shaft body of the water pump rotates, and realizing the recycling of cooling water at the same time;

[0042] During this process, when the grinding speed of the shaft body of an individual water pump shaft is too slow, the control system can start the adjustment mechanism 7 at its bottom to perform special grinding on it, thereby reducing the error precision during the grinding of the shaft bodies of each water pump shaft.

[0043] Such as Figure 3As shown in the figure, a device for grinding the shaft body of a directional water pump shaft provided by the present invention is shown. The telescopic end of the first electric lifting seat 14 is fixedly connected with a fixing plate 41. The bottom surface of the fixing plate 41 is slidably and sealingly connected with a plurality of sliding seats 42. Each sliding seat 42 is connected with a grinding mechanism 5. The fixing plate 41 is fixedly connected with a water tank 43. A first water pump 44 is connected between the water tank 43 and the fixing plate 41.

[0044] In this embodiment, when the first water pump 44 is started, the first water pump 44 can supplement the water in the water tank 43 into the fixing plate 41, thereby increasing the water pressure in the fixing plate 41. Under the pressure of the water pressure in the fixing plate 41, each sliding seat 42 drives each grinding mechanism 5 to extrude and limit the shaft body of each water pump shaft with the same pressure.

[0045] As Figure 4 shown in the figure, a device for grinding the shaft body of a directional water pump shaft provided by the present invention is shown. The bottom surface of the sliding seat 42 is fixedly connected with two telescopic plates 51. The two telescopic plates 51 are arranged oppositely, and the included angle between the two telescopic plates 51 is less than 80 degrees of the power assembly of the workbench 1. The bottom of the sliding seat 42 is fixedly connected with a second electric driving rod 52. The telescopic end of the second electric driving rod 52 is fixedly connected with a sliding telescopic rod 53. The two telescopic ends of the sliding telescopic rod 53 are respectively rotatably connected with the telescopic ends of the telescopic plates 51. The telescopic ends of the telescopic plates 51 are fixedly connected with grinding plates 54.

[0046] In this embodiment, the two telescopic plates 51 on each sliding seat 42 are both clamped outside the shaft body of a water pump shaft. At this time, the telescopic ends of the two telescopic plates 51 both drive a telescopic plate to contact the shaft body of the water pump shaft. When the water pump shaft rotates, the two grinding plates 54 simultaneously grind the shaft body of the water pump shaft. The cooperation between the two grinding plates 54 and the two surface cleaning mechanisms 6 at the bottom can further increase the stability of the shaft body of the water pump shaft during grinding;

[0047] Due to the different roughness of the shaft body of the water pump shaft, it may cause different degrees of wear of each grinding plate 54, thus affecting the consistency of the grinding efficiency of each water pump shaft body. At this time, the control system can control the second electric driving rod 52 on the side of the water pump shaft with a slower grinding speed to extend or contract. At this time, the second electric driving rod 52 drives the grinding plates 54 on both sides of the water pump shaft body to move along the tangent direction of the contact position with the water pump shaft body, so that the unworn area of the grinding plate 54 contacts the water pump shaft body, thereby improving the grinding efficiency of the water pump shaft.

[0048] As Figure 7 shown in the figure, a device for grinding the shaft body of a directional water pump shaft provided by the present invention is shown. Two rotating seats 61 are fixedly arranged on the inner end surface of the water tank 9. The rotating seats 61 are both rotatably connected with rotating rollers 62. A plurality of scraping bars 63 are fixedly connected to the side wall of the rotating rollers 62.

[0049] In this embodiment, through the cooperation of the two rotating rollers 62, not only can the debris at the polished part of the water pump shaft body be cleaned, but also the water stains after the water pump shaft body is cleaned can be removed.

[0050] Furthermore, the two rotating rollers 62 are distributed on both sides of the adjustment mechanism 7. When the adjustment mechanism 7 sprays the water pump shaft body, the two rotating rollers 62 can prevent water stains and debris from splashing. When the adjustment mechanism 7 polishes the water pump shaft body, one of the rotating rollers 62 can clean the debris on the water pump shaft body before the adjustment mechanism 7 polishes, and after the adjustment mechanism 7 polishes, the other rotating roller 62 can clean the debris polished by the adjustment mechanism 7.

[0051] As Figure 8 shown, a water pump shaft body grinding and processing device provided by the present invention. A bottom of the water tank 9 is fixedly connected with an electric push rod 71. A telescopic end of the electric push rod 71 is fixedly connected with a connecting frame 72. The connecting frame 72 is rotatably connected with a grinding roller 74. The connecting frame 72 is fixedly connected with a second motor 73. An output shaft of the second motor 73 is fixedly connected with one end of the grinding roller 74. A second water pump 75 is arranged in the water tank 9. The second water pump 75 is communicated with the grinding roller 74 through a hose. A rotary joint is arranged between the hose and the grinding roller 74. A plurality of through holes are arranged on the grinding roller 74.

[0052] In this embodiment, when the second water pump 75 is started, the second water pump 75 pumps the cooling water in the water tank 9 into the grinding roller 74, and then cools the water pump shaft body through the through holes on the grinding roller 74. At this time, the second motor 73 drives the grinding roller 74 to rotate, thereby increasing the flushing effect on the water pump shaft body.

[0053] When the electric push rod 71 is started, the electric push rod 71 can drive the connecting frame 72 to move upward. The connecting frame 72 drives the grinding roller 74 to move upward. The grinding roller 74 contacts the water pump shaft body. The second motor 73 drives the grinding roller 74 to grind the water pump shaft body, thereby improving the grinding efficiency of the water pump shaft body.

[0054] A water pump shaft body grinding and processing device provided by the present invention. The control system includes:

[0055] A monitoring module, which includes a plurality of pressure sensors. A pressure sensor is arranged between the rotating seat 61 of each rotating roller 62 and the corresponding rotating seat 61. The pressure sensor can detect the vertical pressure received by the rotating roller 62.

[0056] The processing module includes a data processor. Two pressure sensors on two rotating seats 61 in each water tank 9 form a group. The data processor calculates the pressure difference between the two pressure sensors in each group, compares the pressure difference between the two pressure sensors in each group with a preset first threshold, and forms a judgment message.

[0057] The data processor calculates the average pressure of the two pressure sensors in each group, then obtains the maximum difference between the average pressures of each group, compares the maximum difference between the average pressures of each group with a preset second threshold, and forms a judgment message.

[0058] The control module controls the clamping mechanism 2, the grinding mechanism 5, the surface cleaning mechanism 6, and the adjustment mechanism 7 according to the judgment message obtained by the processing module.

[0059] In this embodiment, before grinding, the second electric lifting seat 15 is started to extend. The second electric lifting seat 15 drives all the water tanks 9 to rise in height through the mounting seat 16 and the adjusting bolts 10 at the bottom of each water tank 9, so as to adjust the height of a single water tank 9, so that each roller 62 is in contact with the shaft body of the water pump shaft, and the values of all pressure sensors are roughly the same.

[0060] When the pressure difference between the two pressure sensors in each group exceeds the preset first threshold, it indicates that the shaft body of the water pump shaft is offset at this time. At this time, the control module controls the clamping mechanism 2 to increase the clamping force on the shaft body of the water pump shaft. At the same time, the second electric lifting seat 15 is started to extend, and the second electric lifting seat 15 drives all the surface cleaning mechanisms 6 to further squeeze the shaft body of the water pump shaft. The debris on the shaft body of the water pump is further removed through each surface cleaning mechanism 6, so as to avoid the oscillation frequency of the shaft body of the water pump increasing due to the adhesion of debris during grinding, and each surface cleaning mechanism 6 can increase the limiting degree of the shaft body of the water pump together with each grinding mechanism 5.

[0061] When the maximum difference between the average pressures of each group exceeds the preset second threshold, it indicates that the grinding speed of the shaft body of an individual water pump is slower. At this time, the adjustment mechanism 7 at its bottom is started to rise in height, so that the grinding speed of the water pump shaft is increased. And under the push of the adjustment mechanism 7 at the bottom of the shaft body of the water pump, the adjustment mechanism 7 at the bottom and the two grinding plates 54 above it form a triangular limit for the shaft body of the water pump, increasing the grinding efficiency of the shaft body of the water pump while improving the stability of the shaft body of the water pump during grinding.

[0062] Such as Figure 2As shown in the figure, a grinding device for the shaft body of a directional water pump shaft provided by the present invention is shown. One end of each rotating shaft 12 is fixedly connected with a first gear 32. All the first gears 32 are jointly wound and engaged with a first tooth chain 33. One of the fixed frames 11 is fixedly connected with a first motor 31. The output shaft of the first motor 31 is fixedly connected with one end of one of the rotating shafts 12.

[0063] In this embodiment, when the first motor 31 is started, the first motor 31 drives the first gear 32 connected thereto to rotate. Under the driving action of the first tooth chain 33, all the first gears 32 rotate synchronously in the same direction, so that all the clamping mechanisms 2 drive all the water pump shafts to rotate at the same speed in the same direction.

[0064] As Figure 6 shown in the figure, a grinding device for the shaft body of a directional water pump shaft provided by the present invention is shown. One end of each roller 62 is fixedly connected with a second gear 81. A second tooth chain 82 is wound and engaged between the two second gears 81. The side surface of the mounting seat 16 is slidably connected with a slide plate 83. The slide plate 83 is fixedly connected with a third motor 84. The output shaft of the third motor 84 is fixedly connected with one end of one of the rollers 62.

[0065] In this embodiment, when the third motor 84 is started, the third motor 84 drives one of the second gears 81 to rotate. Under the driving action of the second tooth chain 82, the two second gears 81 drive the two rollers 62 to rotate at the same speed in the same direction simultaneously.

[0066] Working principle:

[0067] Each clamping mechanism 2 fixes the shaft body of each water pump shaft. The first electric lifting seat 14 is started to drive the pressure mechanism 4 to move downward. At this time, each grinding mechanism 5 contacts the shaft body of each water pump shaft. At this time, the pressure mechanism 4 can push a plurality of grinding mechanisms 5 to contact the shaft body with the same extrusion force at the same time, so as to ensure that the grinding forces received by the shaft bodies of each water pump shaft during grinding are equal. And the driving mechanism 3 is started. The driving mechanism 3 drives all the rotating shafts 12 to rotate at the same speed, so that the grinding speeds of each water pump shaft are the same, and further ensures that the shaft bodies of each water pump shaft are ground with the same grinding efficiency, reducing the error precision during the grinding of the shaft bodies of each water pump shaft;

[0068] Further, before grinding, start the second electric lifting seat 15 to extend. The second electric lifting seat 15 drives all the water tanks 9 to move upward through the mounting seat 16. The two surface cleaning mechanisms 6 in each water tank 9 can contact the shaft body of a water pump shaft. During the grinding process, when the shaft body of the water pump shaft passes through the water tank 9, first, a surface cleaning mechanism 6 removes the debris on the shaft body of the water pump shaft. Then, the adjusting mechanism 7 sprays and cools the shaft body to prevent the temperature of the shaft body of the water pump shaft from being too high. After that, the other surface cleaning mechanism 6 scrapes off the water stains on the shaft body of the water pump shaft, thus preventing water splashing when the shaft body of the water pump shaft rotates. At the same time, the recycling of cooling water is realized;

[0069] During this process, when the pressure difference between each group of two pressure sensors exceeds a preset first threshold, it indicates that the shaft body of the water pump shaft is misaligned. At this time, the control module controls the clamping mechanism 2 to increase the clamping force on the shaft body of the water pump shaft. At the same time, start the second electric lifting seat 15 to extend. The second electric lifting seat 15 drives all the surface cleaning mechanisms 6 to further squeeze the shaft body of the water pump shaft. The debris on the shaft body of the water pump shaft is further removed through each surface cleaning mechanism 6, thus preventing the shaft body of the water pump shaft from adhering to debris and increasing the oscillation frequency of the shaft body of the water pump shaft during grinding. And each surface cleaning mechanism 6 can, together with each grinding mechanism 5, increase the limiting degree of the shaft body of the water pump shaft;

[0070] When the maximum difference between the average pressure values of each group exceeds a preset second threshold, it indicates that the grinding speed of the shaft body of an individual water pump shaft is slower. At this time, start the adjusting mechanism 7 at its bottom to rise in height, so that the grinding speed of the water pump shaft increases, thereby reducing the error precision during the grinding of the shaft bodies of each water pump shaft. And under the push of the adjusting mechanism 7 at the bottom of the shaft body of the water pump shaft, the adjusting mechanism 7 at the bottom and the two grinding plates 54 above it form a triangular limit for the shaft body of the water pump shaft, increasing the grinding efficiency of the shaft body of the water pump shaft and improving the stability during the grinding of the shaft body of the water pump shaft.

[0071] At this time, a surface cleaning mechanism 6 in the water tank 9 first removes the debris on the shaft body of the water pump shaft to prevent excessive debris on the shaft body of the water pump shaft from causing excessive vibration of the shaft body of the water pump shaft during grinding by the adjusting mechanism 7 and affecting the grinding effect of the shaft body of the water pump shaft. And the other surface cleaning mechanism 6 can remove the debris and water stains ground by the adjusting mechanism 7 from the shaft body of the water pump shaft, thus preventing the debris ground by the adjusting mechanism 7 from being carried out of the water tank 9 and further affecting the grinding effect of the grinding mechanism 5.

[0072] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.

[0073] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
