Description

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1 , Figure 2 This utility model provides a technical solution: a grinding and cooling circulation device for pump shaft processing, comprising a grinding device 1, a frame 2, a cooling device 3, and a placement device 4. The grinding device 1 and the placement device 4 are both located on the top of the frame 2, the cooling device 3 is located inside the frame 2, and the top surface of the frame 2 is provided with a hollow frame at the position of the placement device 4.

[0020] The frame 2 has a water filter structure 5 on its inner top surface. The frame 2 has multiple columns. An auxiliary water filter structure 6 is rotatably connected to the columns of the frame 2. The auxiliary water filter structure 6 is placed directly below the water filter structure 5. The frame 2 has a water collection tank 7 on its inner bottom surface. The water collection tank 7 is located directly below the auxiliary water filter structure 6 and is connected to the cooling device 3.

[0021] The hollow frame is fixed to the top of the frame 2 by welding to facilitate the downward flow of coolant.

[0022] The grinding device 1 includes a grinding head 11, a lifting device 12, and a support 13. The support 13 is located on the top of the frame 2. The fixed end of the lifting device 12 is connected to the support 13, and the lifting end of the lifting device 12 is connected to the grinding head 11. The height of the grinding head 11 can be flexibly adjusted by the lifting device 12 to adapt to the grinding requirements of pump shafts of different sizes, ensuring the stability and accuracy of the grinding process.

[0023] The cooling device 3 includes a water tank 31, a water pump 32, and an output pipe 33. The water tank 31 is connected to the input end of the water pump 32, and the output end of the water pump 32 is connected to one end of the output pipe 33. The other end of the output pipe 33 is connected to the lifting end of the lifting device 12. The water tank 31 is connected to the water collection tank 7. The water pump 32 draws coolant from the water tank 31 and delivers it to the vicinity of the grinding head 11 through the output pipe 33 to cool the pump shaft that is being ground. The cooled coolant is collected and returned to the water tank 31, realizing the recycling of coolant. A check valve can be installed on the output pipe 33 for more flexible control.

[0024] Furthermore, the output pipe 33 includes a support pipe 331 and a flexible hose 332. One end of the support pipe 331 is connected to the output end of the water pump 32, and the other end of the support pipe 331 is connected to one end of the flexible hose 332. The other end of the flexible hose 332 is connected to the lifting end of the lifting device 12. The support pipe 331 serves to fix and support the device, while the flexible hose 332 has a certain degree of flexibility, allowing it to extend and retract flexibly with the lifting device 12, ensuring that the coolant can be accurately delivered to the grinding head 11.

[0025] The placement device 4 includes a slide rail 41, a motor 42, a slider 43, and a placement platform 44. The slide rail 41 is disposed on the top surface of the frame 2, and the slider 43 is slidably connected to the slide rail 41. The motor 42 is disposed on the top surface of the frame 2, and the drive end of the motor 42 is threadedly connected to the slider 43 via a lead screw. The placement platform 44 is disposed on the top surface of the slider 43. The motor 42 drives the lead screw to rotate, causing the slider 43 to slide on the slide rail 41, thereby realizing the movement of the placement platform 44. This facilitates the accurate placement of the pump shaft under the grinding head 11 for grinding, and also facilitates the adjustment of the pump shaft's position to meet different processing requirements.

[0026] The water filtration structure 5 includes a first water filtration chamber 51, a second water filtration chamber 52, and a first filter screen 53. The first water filtration chamber 51 is disposed on the inner top surface of the frame 2. The top surface of the second water filtration chamber 52 is connected to the bottom surface of the first water filtration chamber 51. The first filter screen 53 is provided at the connection between the first water filtration chamber 51 and the second water filtration chamber 52. The bottom of the second water filtration chamber 52 is provided with a water outlet. During the grinding process, coolant and grinding debris and other impurities flow into the first water filtration chamber 51 through the hollow frame on the top surface of the frame 2. The first filter screen 53 performs preliminary filtration of the impurities, intercepting larger debris. The filtered coolant flows into the second water filtration chamber 52 and then flows out from the water outlet.

[0027] The auxiliary water filtration structure 6 includes a second filter screen 61, a rotating connecting sleeve 62, and a connecting rod 63. The second filter screen 61 is connected to the rotating connecting sleeve 62 via the connecting rod 63. The rotating connecting sleeve 62 is mounted on the column of the frame 2 via a bearing. The second filter screen 61 is located directly below the outlet of the second water filtration chamber 52. The coolant flowing out of the outlet of the second water filtration chamber 52 falls onto the second filter screen 61 for secondary filtration, removing finer impurities and ensuring a high level of cleanliness for the coolant entering the collection tank 7. Simultaneously, the second filter screen 61 is rotatably connected to the column of the frame 2 via the rotating connecting sleeve 62 and the connecting rod 63, facilitating its removal for cleaning or replacement when needed. Furthermore, the outer circumference of the rotating connecting sleeve 62 can be provided with a handle for easier operation by staff.

[0028] It should be noted that the mesh size of the second filter screen 61 is much smaller than that of the first filter screen 53, so that large particles can be kept in the second filter screen 61 to the greatest extent and not enter the water collection tank 7.

[0029] Working principle: The pump shaft to be processed is placed on the placement platform 44, and the motor 42 is started. The motor 42 drives the slider 43 to move on the slide rail 41 through the lead screw, moving the pump shaft to the appropriate processing position.

[0030] The lifting device 12 is activated to lower the grinding head 11 to a position in contact with the pump shaft, and the grinding process on the pump shaft begins.

[0031] The water pump 32 is started, drawing coolant from the water tank 31 and delivering it to the grinding head 11 through the output pipe 33 to cool the grinding area. After use, the coolant, carrying grinding debris and impurities, drips through the perforated frame on the top surface of the frame 2 into the water filter structure 5.

[0032] The coolant first enters the first filtration chamber 51, undergoes preliminary filtration by the first filter screen 53, and then enters the second filtration chamber 52. From the outlet at the bottom of the second filtration chamber 52, it drips onto the second filter screen 61 of the auxiliary filtration structure 6 for secondary filtration. The filtered coolant flows into the water collection tank 7, and then returns to the water tank 31 through the connecting pipe between the water collection tank 7 and the water tank 31, thus achieving coolant recycling.
