Description

Technical Field

[0001] This disclosure relates to the field of processing technology for circulating pump parts, and more specifically, to a grinding device. Background Technology

[0002] A circulating pump is a centrifugal pump specifically designed for conveying easily vaporized substances. The saturated vapor pressure of the conveyed medium is higher than the vapor pressure of a gas-liquid two-phase mixture, causing the medium to change from a liquid to a gaseous state upon entering the pump body. Circulating pumps have a high gas conveying capacity, allowing the conveyed medium to flow in a boiling state and minimizing liquid vaporization losses. During the manufacturing process of a circulating pump, its components require grinding. In related technologies, grinding equipment for bearings or thrust discs requires clamping the thrust disc around the parts to be ground. This effectively increases the clamping effect of the thrust disc, preventing movement during grinding and ensuring its stability. However, after prolonged use, the grinding wheel generates a large amount of heat. Since it lacks heat dissipation capabilities, rapid heat dissipation is difficult, easily leading to damage to the grinding wheel. Overheating also reduces grinding quality and affects subsequent processing efficiency. Summary of the Invention

Detailed Implementation

[0018] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0019] In this disclosure, unless otherwise stated, directional terms such as "inner" and "outer" refer to the outline of the corresponding component itself; directional terms such as "upper," "lower," "top," "bottom," "horizontal," and "vertical" are defined based on the usage habits of the heaters provided in this disclosure. Specifically, please refer to... Figure 1 In the diagrams shown, the direction indicated by the Z-arrow is top and apex, and vice versa; the X-direction indicates the horizontal direction, and the Z-direction indicates the vertical direction. Terms such as "first" and "second" used in this disclosure are for distinguishing one element from another and do not indicate sequence or importance. Furthermore, in the following description, when referring to the accompanying drawings, the same reference numerals in different drawings denote the same or similar elements.

[0020] Reference Figure 1 This disclosure provides a grinding apparatus, which may include a grinding wheel 1 for grinding parts and a spray assembly 2 for spraying rinsing fluid onto the grinding wheel 1. The grinding wheel 1 may include a wheel body 11, a water outlet 13, and a cooling channel 14. The wheel body 11 may be constructed to be hollow inside so that the wheel body 11 can be used to contain the rinsing fluid. In this way, when the spray assembly 2 sprays rinsing fluid onto the outer surface of the grinding wheel 1 to cool and rinse the outside of the grinding wheel 1, the rinsing fluid sprayed by the spray assembly 2 can also reach the inside of the grinding wheel 1 to cool the inside of the grinding wheel 1. A receiving tank 12 can be disposed on the top of the wheel body 11 for storing rinsing fluid. In the embodiments provided in this disclosure, the top of the receiving tank 12 can be open to receive a maximum amount of rinsing fluid, thereby improving the receiving efficiency of the rinsing fluid and enhancing the cooling effect on the top surface of the wheel body 11. A water inlet hole 15 communicating with the receiving tank 12 can be provided on the top of the wheel body 11, so that the rinsing fluid inside the receiving tank 12 can be passed through the water inlet hole 15 to the interior of the wheel body 11, thereby cooling the interior of the wheel body 11. A water outlet hole 13 can be provided at the bottom of the wheel body 11, and the water outlet hole 13 can be used to spray out the rinsing fluid inside the wheel body 11. In this way, the rinsing fluid sprayed by the spray assembly 2 can be continuously injected into the interior of the wheel body 11, flow through the wheel body 11 and complete heat exchange with the wheel body 11 before being discharged, forming a closed-loop heat dissipation cycle, carrying away the heat inside the grinding wheel 1, effectively improving the cooling and rinsing effect of the grinding wheel 1, and effectively realizing the rapid heat dissipation of the grinding wheel 1. Figure 3 As shown, the cooling channel 14 can be radially extended along the bottom of the wheel body 11, and the cooling channel 14 can be connected between the wheel body 11 and the water outlet 13, so that when the rinsing liquid is discharged through the water outlet 13, the rinsing liquid can flow along the extension path of the cooling channel 14, thereby exchanging heat and cooling the bottom surface of the wheel body 11, so as to improve the cooling efficiency of the grinding wheel 1.

[0021] Through the above technical solution, the grinding wheel 1 is configured as a hollow structure that can contain the rinsing liquid, and a receiving tank 12 for temporarily storing the rinsing liquid is provided on the top of the grinding wheel 1. A cooling channel 14 and a water outlet 13 for discharging the rinsing liquid are provided at the bottom of the grinding wheel 1. This allows the spray assembly 2 to simultaneously perform all-round rinsing and cooling on the outer surface and inside of the grinding wheel 1, and remove the debris adhering to the surface of the grinding wheel 1. This greatly improves the heat dissipation efficiency of the grinding wheel 1, extends the service life of the grinding wheel 1, and improves processing efficiency.

[0022] Reference Figure 1 and Figure 2 The spray assembly 2 may include a first nozzle 21 and a second nozzle 22. The first nozzle 21 can spray rinsing fluid horizontally toward the outer surface of the wheel body 11. In the embodiments provided in this disclosure, the first nozzle 21 can be installed in a fixed position and remain stationary while continuously spraying rinsing fluid, while the grinding wheel 1 can rotate continuously during the rinsing process, thereby achieving comprehensive rinsing of the peripheral wall of the grinding wheel 1. The second nozzle 22 can spray rinsing fluid from top to bottom into the receiving tank 12, so that the receiving tank 12 and the wheel body 11 can be filled with rinsing fluid, thereby achieving cooling of the top surface and interior of the grinding wheel 1.

[0023] Reference Figure 3 The number of cooling channels 14 can be multiple, and these channels 14 can be radially distributed around the center of the wheel body 11. This effectively increases the contact area between the coolant and the bottom surface of the wheel body 11, thereby increasing the cooling area of ​​the wheel body 11 and thus improving the cooling rate of the wheel body 11. Multiple water outlets 13 can be provided corresponding to the cooling channels 14, such as... Figure 3 In the embodiment shown, multiple cooling channels 14 can be interconnected at one end near the center of the wheel body 11 through through holes 16, and water outlet holes 13 can be provided at the other end of the cooling channels 14, thereby effectively improving the discharge effect of coolant, so as to provide coolant circulation and cooling rate of wheel body 11.

[0024] Reference Figure 1The grinding equipment provided in this disclosure may further include a support platform 3 and a clamping member 4. The support platform 3 can be used to place the parts to be ground to ensure the stability of the parts during the grinding process. It is understood that, for grinding purposes, the parts can be spaced vertically from the support platform 3 during the grinding process. In this case, the support platform 3 can avoid contact with the parts, facilitating the falling of grinding debris and heat dissipation, and also acting as a buffer in case the parts accidentally fall. The clamping member 4 can be installed on the support platform 3 to clamp the parts. In the embodiments provided in this disclosure, the clamping member 4 can be composed of two clamping plates that can move closer to or further away from each other to meet the clamping needs of parts with different sizes and structures. Grinding wheels 1 can be spaced apart on the top of the support platform 3, and the grinding wheels 1 can be configured to reciprocate vertically towards or away from the clamping member 4 to adjust their position according to the grinding needs of the parts, thereby meeting the grinding requirements of the parts.

[0025] Reference Figure 1 The grinding equipment may further include a first drive assembly 51 for driving the grinding wheel 1 to reciprocate vertically. The first drive assembly 51 may include a cylinder 511 and a piston rod 512. The cylinder 511 may be spaced apart on the top of the support platform 3 to avoid interference with the parts to be ground. One end of the piston rod 512 may be fixedly connected to the grinding wheel 1, and the other end of the piston rod 512 may extend and retract vertically within the cylinder 511 to drive the grinding wheel 1 to move in the opposite vertical direction, thereby ensuring the vertical position adjustment accuracy of the grinding wheel 1. In the unit embodiment provided in this disclosure, the grinding equipment may further include a motor 53 for driving the grinding wheel 1 to rotate circumferentially to achieve grinding work. The motor 53 may be connected between the grinding wheel 1 and the piston rod 512 to ensure the driving effect of the grinding wheel 1 and the integrity between the components.

[0026] Reference Figure 1 and Figure 2The grinding equipment may also include a collection tank 61 and a second drive assembly 52. ​​The collection tank 61 can be used to store rinsing fluid, and it can be positioned on the support platform 3 and horizontally spaced from the clamping member 4 to avoid interference between them. The spray assembly 2 can be spaced above the collection tank 61 to collect and store the rinsing fluid sprayed by the spray assembly 2 through the collection tank 61. The second drive assembly 52 can drive the grinding wheel 1 to reciprocate horizontally towards or away from the spray assembly 2. On one hand, the second drive assembly 52 can adjust the horizontal position of the grinding wheel 1 according to grinding requirements. By cooperating with the first drive assembly 51, it effectively improves the flexibility of the grinding wheel 1 in different vertical and horizontal positions, thereby effectively improving the applicability of the grinding equipment. On the other hand, the second drive assembly 52 can promptly move the grinding wheel 1 to the position of the spray assembly 2 when grinding is paused or when cooling and rinsing are required.

[0027] Further, refer to Figure 1 The second drive assembly 52 can be spaced apart on the top of the support platform 3, and the second drive assembly 52 can include a lead screw 521 and a sleeve 522. The lead screw 521 can extend horizontally, and an external thread can be provided on the outer wall of the lead screw 521. The inner wall of the sleeve 522 can be formed with an internal thread that can mate with the external thread, so that it can be threaded onto the outer wall of the lead screw 521. The cylinder body 511 can be fixedly connected to the sleeve 522. In the embodiments provided in this disclosure, the grinding device can also include a lead screw motor 524 that can drive the lead screw 521 to rotate. When the lead screw motor 524 drives the lead screw 521 to rotate in different directions, the sleeve 522 can move back and forth along the extension direction of the lead screw 521, so as to drive the cylinder body 511 to move the grinding wheel 1 back and forth, thereby realizing the horizontal position adjustment of the grinding wheel 1.

[0028] Reference Figure 1The grinding equipment may also include a support plate 7. The cross-section of the support plate 7 may be constructed as a U-shaped structure with the opening facing the support platform 3. The side plates 71 on both sides of the opening of the U-shaped structure may be supported on the support platform 3 in a vertical direction. In this disclosure, the two side plates 71 are symmetrically arranged along the interval direction of the clamping member 4 and the liquid collection tank 61, and are respectively arranged on the outer side of the clamping member 4 and the liquid collection tank 61 to form a semi-enclosed structure, which partially isolates the clamping member 4 and the liquid collection tank 61 from the external environment, thereby ensuring the safety of the grinding equipment during use. A horizontal plate 72 connected between the two side plates 71 can be used to install the first drive assembly 51 and the second drive assembly 52. ​​The second drive assembly 52 may include two mounting plates 523 fixedly to the top surface of the horizontal plate 72 at a distance along the horizontal direction. The two ends of the lead screw 521 can be rotatably connected to the mounting plates 523 to realize the installation of the second drive assembly 52. ​​The horizontal plate 72 may be provided with an opening 721 extending in the horizontal direction, and the extension length of the opening 721 is not less than the distance between the clamping member 4 and the liquid collection tank 61. The cylinder body 511 can be attached to the horizontal plate 72 near the piston rod 512 to ensure the stability of the cylinder body 511 installation. The piston rod 512 can extend downward from the horizontal plate 72 through the opening 721 to avoid the horizontal plate 72 interfering with the horizontal movement of the first drive assembly 51. The width of the opening 721 can match the outer diameter of the piston rod 512 to limit the piston rod 512 in the radial direction, thereby preventing the piston rod 512 from shaking during the movement of the grinding wheel 1.

[0029] Reference Figure 1 and Figure 2 The collection tank 61 can be recessed downwards into the top surface of the support platform 3, and the opening of the collection tank 61 can be formed on the support platform 3 so that the top edge of the collection tank 61 can match the height of the top surface of the support platform 3, thereby improving the overall effect of the grinding equipment. The grinding equipment may also include a housing 62 and a filter screen 63. The collection tank 61 can be used to collect the waste rinsing liquid after the spray assembly 2 rinses the grinding wheel 1. The housing 62 can be connected to the bottom of the collection tank 61, and the outer contour edge of the filter screen 63 abuts against the inner wall of the housing 62 so that the rinsing water in the collection tank 61 is filtered and then passed into the housing 62, thereby facilitating the recycling of the waste rinsing liquid.

[0030] like Figure 4 and Figure 5As shown, the filter screen 63 can be detachably connected to the housing 62 laterally. In the embodiments provided in this disclosure, a support strip 64 for supporting the filter screen 63 can be installed on the inner wall of the housing 62, so that the filter screen 63 can be disassembled or installed when cleaning or replacement is required. The side wall of the housing 62 can be formed with a socket for removing or inserting the filter screen 63 to facilitate the movement of the filter screen 63. In the embodiments provided in this disclosure, an outer contour ruler can be fixedly connected to the side edge of the filter screen 63. The sealing plate 621, with a dimension larger than the outer contour of the inlet, fits snugly against the housing 62 when the filter screen 63 is installed. This effectively improves the sealing effect of the housing 62 and prevents leakage of the flushing fluid inside the housing 62. The side of the sealing plate 621 closest to the housing 62 may have a lateral protrusion whose outer contour matches the inner contour of the inlet. This allows the protrusion to fit precisely into the inlet when the sealing plate 621 is fitted against the housing 62, further enhancing the sealing effect of both the sealing plate 621 and the housing 62. Furthermore, the sealing plate 621 significantly reduces the difficulty of moving the filter screen 63. The side of the housing 62 that is in contact with the sealing plate 621 may be provided with multiple screws 622. The sealing plate 621 may be provided with multiple through holes corresponding to the screws 622, so that when the sealing plate 621 and the housing 62 are connected, the screws 622 can pass through the through holes. In order to further improve the connection strength between the sealing plate 621 and the housing 62, one end of the screw 622 may extend out of the through hole and be screwed with a nut 623.

[0031] Reference Figure 2 The grinding equipment may also include a pump body 81 and a liquid outlet pipe 82. The pump body 81 can be used to pump the rinsing liquid in the tank 62 to output the rinsing liquid in the tank 62. The liquid outlet pipe 82 can be connected between the pump body 81 and the spray assembly 2 to deliver the rinsing liquid pumped out by the pump body 81 to the spray assembly 2. In the embodiments provided in this disclosure, when the spray assembly 2 includes the first nozzle 21 and the second nozzle 22 mentioned above, the end of the liquid outlet pipe 82 that is connected to the spray assembly 2 can be configured as an inverted L-shaped structure with its opening facing the collection tank 61. The second nozzle 22 can be installed on the horizontal section of the L-shaped structure, and the first nozzle 21 can be installed on the vertical section of the L-shaped structure, so that the first nozzle 21 and the second nozzle 22 can spray the rinsing liquid in different directions respectively.

However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.
