Description

Technical Field

[0001] This invention relates to the field of flow channel polishing technology, specifically to a dual-flow channel pump body polishing device and its process. Background Technology

[0002] A pump is a device that converts mechanical energy into fluid energy using external power. The pump's flow channel refers to the internal "channel system" that guides the fluid flow. It is the complete path through which the fluid enters the pump body from the "inlet," undergoes energy conversion, and is finally discharged from the "outlet." It is not only a "channel" for the fluid but also a key carrier for realizing the "conversion of mechanical energy into fluid energy." Its shape, size, and surface quality directly affect the pump's core indicators such as efficiency, cavitation resistance, vibration, and noise.

[0003] In pump body manufacturing, burrs, flash, and unevenness are easily generated on the inner wall after casting or welding. Uneven machining allowances may also lead to excessive surface roughness. These problems can seriously damage the fluid dynamics characteristics within the flow channel: a rough inner wall increases fluid flow resistance, reducing the pump's hydraulic efficiency by 5%-15% and increasing energy consumption; sharp burrs or recesses can easily form eddies and local pressure surges, accelerating wear and corrosion of the pump's inner wall, shortening equipment lifespan, and even causing safety hazards such as fluid delivery interruption and equipment failure. Therefore, high-precision grinding of the pump's inner wall and flow channel surface is a key process to ensure equipment performance.

[0004] With the advancement of technology, there are more and more types of pumps, and pump bodies are developing towards multi-channel designs. The design of multi-channel designs increases the difficulty of grinding. Currently, the industry mainly uses manual grinding for pump body flow channels. However, manual grinding tools are difficult to penetrate deeply, which not only fails to ensure uniform grinding but also easily leads to local over-grinding or under-grinding, resulting in deviations in flow channel dimensional accuracy and affecting the hydraulic performance of the pump body.

[0005] Therefore, a dual-channel pump body grinding device and its process are needed to solve the above problems. Summary of the Invention

[0006] To address the aforementioned problem, namely the difficulty in grinding the pump body flow channel, this invention provides a dual-flow channel pump body grinding device and its process.

[0007] A dual-channel pump body grinding device includes a frame structure. The frame structure includes a base with a feed inlet. An abrasive flow feeding section is provided on the lower side of the base and communicates with the feed inlet. A mounting bracket is provided on the base, and two sealing plates are symmetrically slidably arranged on the mounting bracket. The sealing plates are located on the upper side of the base, and a workpiece to be ground is arranged between the two sealing plates. The workpiece to be ground includes a pump body. Two horizontally arranged flow channels are symmetrically opened in the pump body. The two sealing plates are used to block the two flow channels. A vertically arranged mounting groove is opened in the pump body and communicates with the two flow channels.

[0008] Furthermore, the mounting slot is used for mounting other components of the pump body.

[0009] Furthermore, the abrasive flow feeding section is used to transport abrasive into the feed inlet. The abrasive flow feeding section is existing technology and will not be described in detail here.

[0010] Specifically, during use, the pump body is placed on the inlet, and the mounting slot is aligned with the inlet. Then, the two sealing plates are moved to block the openings of the two flow channels. The abrasive flow feeding unit is then activated, which delivers the abrasive into the inlet. The abrasive then enters the mounting slot through the inlet. As the abrasive is continuously fed, it accumulates upwards in the mounting slot and then into the flow channels. Initially, the abrasive flows at the bottom of the flow channels. As it is blocked by the sealing plates, it gradually accumulates upwards. Once the mounting slot and flow channels are full, the two sealing plates are moved to open the openings of the two flow channels. The abrasive then flows out of the flow channels, grinding the inner wall of the pump body under the continuous flow of the abrasive.

[0011] The feed inlet provides support for the pump body and allows the abrasive supplied by the abrasive flow feed unit to be guided into the pump body. Under the action of the abrasive flow feed unit, the abrasive is continuously fed into the pump body, thereby achieving the purpose of grinding the flow channel and mounting groove. Compared with manual grinding, the grinding effect is more uniform and the grinding efficiency is higher. The sealing plate can close the flow channel before the abrasive fills the pump body, preventing the abrasive from flowing out of the pump body before it is full.

[0012] Preferably, the sealing plate is provided with an auxiliary mechanism that extends into the flow channel. The auxiliary mechanism includes an arc-shaped auxiliary plate, the outer circular side of which can contact the inner wall of the flow channel.

[0013] Specifically, initially, the auxiliary plate is located in the flow channel and is not in contact with the inner wall of the flow channel. After the abrasive flows in the flow channel for a period of time, the auxiliary plate is moved so that its outer circumference contacts the inner wall of the flow channel, and a portion of the auxiliary plate moves to the upper side of the mounting groove, while the other portion contacts the inner wall of the flow channel (because the abrasive has the most contact with the right angle between the mounting groove and the flow channel during the process of flowing from the mounting groove into the flow channel, over-grinding is likely to occur here, causing this area to be recessed compared to other parts of the flow channel, resulting in turbulence in the flow channel during subsequent use and affecting fluid delivery). Afterward, the abrasive flows into the flow channel from the gap between the two auxiliary plates.

[0014] By setting up auxiliary plates, after the abrasive has been grinding the flow channel for a period of time, the auxiliary plates can be moved to the upper side of the mounting groove and brought into contact with the inner wall of the flow channel. This protects part of the inner wall of the right-angle connection between the flow channel and the mounting groove, preventing it from contacting the abrasive again and avoiding over-grinding that could affect the flow channel's smoothness. At the same time, due to the obstruction of the auxiliary plates, the abrasive mainly flows through the gap between the two auxiliary plates, reducing the abrasive flow velocity at the right-angle connection between the mounting groove and the flow channel. This reduces wear at the right-angle connection of the mounting groove and ensures the installation of subsequent structures.

[0015] Preferably, the auxiliary plate is connected to a moving component, which is used to drive the auxiliary plate to move.

[0016] Specifically, after the pump body is polished, the abrasive is discharged from the pump body, and the moving parts are activated. The moving parts drive the auxiliary plate to rotate and move the auxiliary plate up and down, so that the auxiliary plate impacts the inner wall of the flow channel through the gap, causing the pump body to vibrate. At the same time, the auxiliary plate moves horizontally, impacting various parts of the inner wall of the flow channel in sequence.

[0017] Through the coordinated action of the moving parts and the auxiliary plate, the moving parts can drive the auxiliary plate to move during the grinding process, allowing the auxiliary plate to contact the inner wall of the flow channel and protect the inner wall of the flow channel. After grinding, the moving parts can continuously impact the inner wall of the flow channel, causing the pump body to vibrate and scrape the inner wall of the flow channel. This removes the abrasive adhering to the inner wall of the auxiliary flow channel and the mounting groove, preventing excessive abrasive adhering to the inner wall of the flow channel from affecting subsequent processing.

[0018] Preferably, the moving component includes a first electric actuator fixedly connected to the sealing plate, a first motor fixedly connected to the output end of the first electric actuator, a rotating rod fixedly connected to the output end of the first motor, the rotating rod passing through the sealing plate, the rotating rod extending into the flow channel, and the rotating rod being connected to the auxiliary plate.

[0019] Specifically, when the auxiliary plate needs to move, the first electric actuator is activated, the output end of the first electric actuator moves horizontally, the output end of the first electric actuator drives the first motor to move, the output end of the first motor drives the rotating rod to move horizontally, the rotating rod drives the auxiliary plate to move horizontally, and at the same time the first motor is activated, the output end of the first motor drives the rotating rod to rotate, the rotating rod drives the auxiliary plate to rotate.

[0020] The first electric actuator can drive the auxiliary plate to move horizontally, and the first motor can drive the auxiliary plate to rotate.

[0021] Preferably, the moving component further includes a slot formed in the rotating rod, a second electric actuator is fixedly connected in the slot, a push plate is fixedly connected to the output end of the second electric actuator, hydraulic oil is provided in the cavity between the push plate and the inner wall of the slot, a fixed sleeve is fixedly fitted on the rotating rod, an elastic telescopic rod is fixedly connected to the fixed sleeve, a connecting slot is formed in the rotating rod, one end of the connecting slot is connected to the slot, and the other end of the connecting slot is connected to the internal space of the elastic telescopic rod.

[0022] Specifically, when the auxiliary plate needs to be aligned with the inner wall of the flow channel, the second electric actuator is activated. The output end of the second electric actuator drives the push plate to move, causing the push plate to push hydraulic oil into the connecting groove. Then, the hydraulic oil enters the elastic telescopic rod through the connecting groove, causing the elastic telescopic rod to extend. The output end of the elastic telescopic rod drives the auxiliary plate to align with the inner wall of the flow channel. When the auxiliary plate needs to be reset, the second electric actuator is reset. The elastic telescopic rod resets under its own elastic force, simultaneously driving the auxiliary plate to reset and squeezing the hydraulic oil back into the groove.

[0023] Preferably, a movable component is provided between the mounting frame and the sealing plate. The movable component includes two second motors symmetrically fixedly connected to the mounting frame. A lead screw is fixedly connected to the output end of the second motor. A connecting plate is threadedly connected to the lead screw. The connecting plate is fixedly connected to the sealing plate.

[0024] Specifically, when the sealing plate needs to be moved during use, the second motor is started. The output of the second motor drives the lead screw to rotate, the lead screw drives the connecting plate to move, and the connecting plate drives the sealing plate to move.

[0025] Preferably, two limiting members are symmetrically arranged on the lower side of the mounting frame. Each limiting member includes a third electric actuator fixedly connected to the mounting frame. An arc-shaped limiting plate is fixedly connected to the bottom output end of the third electric actuator. The limiting plate can abut against the upper side of the pump body.

[0026] Specifically, during use, after the pump body is placed on the feed inlet, the third electric actuator is activated. The output end of the third electric actuator drives the limit plate to move downward. The limit plate abuts against the upper side of the pump body, and at the same time, it works with the feed inlet to limit the pump body and prevent the pump body from moving during the grinding process.

[0027] Preferably, the base has two symmetrical openings, and a collection box is provided under each opening.

[0028] Specifically, during use, after the abrasive flows out of the channel, it falls into the collection box for collection.

[0029] Furthermore, the sealing plate has multiple protrusions evenly arranged along the circumference on one side near the pump body.

[0030] Specifically, when the sealing plate blocks the opening of the flow channel, the gap between the sealing plate and the pump body is created by the protrusions. This allows the gas inside the pump body to be discharged when the abrasive is fed into the pump body, preventing gas from mixing into the abrasive and affecting its compactness.

[0031] In addition, the present invention also provides a dual-flow-channel pump body polishing process, comprising the following steps: S1: Clamp the pump body; S2: Connect one of the openings in the pump body to the abrasive flow device; S3: Block off other flow channels in the pump body; S4: Start the abrasive flow equipment and feed abrasive into the flow channel; S5: After the abrasive fills the pump body, the blocked flow channel is opened, allowing the abrasive to flow out.

[0032] The beneficial effects of this invention are as follows: 1. The present invention, through the setting of the feed inlet, can support the pump body and guide the abrasive supplied by the abrasive flow feed unit into the pump body; and under the action of the abrasive flow feed unit, the abrasive is continuously fed into the pump body, thereby achieving the purpose of grinding the flow channel and the mounting groove. Compared with manual grinding, the grinding effect is more uniform and the grinding efficiency is higher; through the setting of the sealing plate, the flow channel can be sealed when the abrasive does not fill the pump body, preventing the abrasive from flowing out of the pump body before it is full.

[0033] 2. By using auxiliary plates, this invention allows the auxiliary plates to be moved to the upper side of the mounting groove after the abrasive has been grinding the flow channel for a period of time. The auxiliary plates then contact the inner wall of the flow channel, protecting part of the inner wall of the right-angle connection between the flow channel and the mounting groove, preventing further contact with the abrasive and avoiding over-grinding that could affect the flow channel's flowability. Simultaneously, due to the obstruction of the auxiliary plates, the abrasive mainly flows through the gap between the two auxiliary plates, reducing the abrasive flow velocity at the right-angle connection between the mounting groove and the flow channel, thus reducing wear at this point and ensuring the installation of subsequent structures.

[0034] 3. This invention utilizes the coordinated action of the moving parts and the auxiliary plate to enable the moving parts to drive the auxiliary plate during the grinding process. This allows the auxiliary plate to contact the inner wall of the flow channel, protecting it. Furthermore, after grinding, the moving parts continuously impact the inner wall of the flow channel, causing the pump body to vibrate and scrape the inner wall. This removes the abrasive adhering to the inner wall of the auxiliary flow channel and the mounting groove, preventing excessive abrasive adhering to the inner wall of the flow channel from affecting subsequent processing.

[0037] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0038] like Figure 1 , Figure 3 As shown in the figure, an embodiment of the present invention discloses a dual-channel pump body grinding device, including a frame structure 1. The frame structure 1 includes a base 11, on which a feed inlet 12 is provided. An abrasive flow feeding part 13 is provided on the lower side of the base 11, and the abrasive flow feeding part 13 is connected to the feed inlet 12. A mounting bracket 14 is provided on the base 11, and two sealing plates 15 are symmetrically slidably arranged on the mounting bracket 14. The sealing plates 15 are located on the upper side of the base 11, and a workpiece 2 to be ground is provided between the two sealing plates 15. The workpiece 2 to be ground includes a pump body 21. Two horizontally arranged flow channels 22 are symmetrically opened in the pump body 21. The two sealing plates 15 are used to block the two flow channels 22. A vertically arranged mounting groove 23 is opened in the pump body 21, and the mounting groove 23 is connected to the two flow channels 22.

[0039] Furthermore, the mounting slot 23 is used for mounting other components of the pump body.

[0040] Furthermore, the abrasive flow feeding unit 13 is used to transport abrasive into the feed inlet 12. The abrasive flow feeding unit 13 is existing technology and will not be described in detail here.

[0041] Specifically, during use, the pump body is placed on the inlet 12, and the mounting groove 23 is aligned with the inlet 12. Then, the two sealing plates 15 are moved to block the openings of the two flow channels 22. The abrasive flow feeding unit 13 is then activated, which delivers the abrasive to the inlet 12. The abrasive then enters the mounting groove 23 through the inlet 12. As the abrasive is continuously delivered, it accumulates upward in the mounting groove 23. The abrasive then accumulates in the flow channel 22 and initially flows at the bottom of the flow channel 22. After being blocked by the sealing plates 15, the abrasive gradually accumulates upward. When the abrasive fills the mounting groove 23 and the flow channel 22, the two sealing plates 15 are moved to open the openings of the two flow channels 22. The abrasive then flows out from the flow channel 22, and the inner wall of the pump body 21 is polished by the continuous flow of the abrasive.

[0042] The feed inlet 12 supports the pump body 21 and allows the abrasive supplied by the abrasive flow feed section 13 to be introduced into the pump body 21. Under the action of the abrasive flow feed section 13, the abrasive is continuously fed into the pump body 21, thereby achieving the purpose of grinding the flow channel 22 and the mounting groove 23. Compared with manual grinding, the grinding effect is more uniform and the grinding efficiency is higher. The sealing plate 15 can close the flow channel 22 when the abrasive does not fill the pump body 21, preventing the abrasive from flowing out of the pump body 21 before it is full.

[0043] like Figure 1 , Figure 3 , Figure 4 , Figure 7 As shown, the sealing plate 15 is provided with an auxiliary mechanism 3, which extends into the flow channel 22. The auxiliary mechanism 3 includes an arc-shaped auxiliary plate 31, the outer circular side of which can contact the inner wall of the flow channel 22.

[0044] Specifically, initially, the auxiliary plate 31 is located in the flow channel 22, and the auxiliary plate 31 is not in contact with the inner wall of the flow channel 22. After the abrasive flows in the flow channel 22 for a period of time, the auxiliary plate 31 is moved so that the outer circumference of the auxiliary plate 31 contacts the inner wall of the flow channel 22, and a part of the auxiliary plate 31 moves to the upper side of the mounting groove 23, while the other part contacts the inner wall of the flow channel 22 (because the abrasive has the most contact with the right angle connection between the mounting groove 23 and the flow channel 22 during the process of the abrasive flowing from the mounting groove 23 into the flow channel 22, over-grinding is likely to occur here, causing this part to be recessed compared to other parts of the flow channel 22, resulting in turbulence in the flow channel 22 during subsequent use and affecting fluid transport). After that, the abrasive flows into the flow channel 22 from the gap between the two auxiliary plates 31.

[0045] By setting the auxiliary plate 31, after the abrasive has been grinding the flow channel 22 for a period of time, the auxiliary plate 31 can be moved to the upper side of the mounting groove 23 and brought into contact with the inner wall of the flow channel 22. This protects part of the inner wall of the right-angle connection between the flow channel 22 and the mounting groove 23, preventing it from contacting the abrasive and avoiding over-grinding that could affect the flow of the flow channel 22. At the same time, due to the obstruction of the auxiliary plate 31, the abrasive mainly flows through the gap between the two auxiliary plates 31, which reduces the abrasive flow velocity at the right-angle connection between the mounting groove 23 and the flow channel 22, reducing wear at the right-angle connection of the mounting groove 23 and ensuring the installation of subsequent structures.

[0046] like Figure 3 As shown, the auxiliary plate 31 is connected to a moving component 32, which is used to drive the auxiliary plate 31 to move.

[0047] Specifically, after the pump body 21 is polished, the abrasive is discharged from the pump body 21, and the moving part 32 is started. The moving part 32 drives the auxiliary plate 31 to rotate and move the auxiliary plate 31 up and down, so that the auxiliary plate 31 impacts the inner wall of the flow channel 22 at intervals, causing the pump body 21 to vibrate. At the same time, the auxiliary plate 31 moves horizontally and impacts various parts of the inner wall of the flow channel 22 in sequence.

[0048] Through the coordinated action of the moving part 32 and the auxiliary plate 31, the moving part 32 can drive the auxiliary plate 31 to move during the grinding process, so that the auxiliary plate 31 can contact the inner wall of the flow channel 22 and protect the inner wall of the flow channel 22. After grinding, the moving part 32 can continuously impact the inner wall of the flow channel 22, causing the pump body 21 to vibrate and scrape the inner wall of the flow channel 22. The abrasive adhering to the inner wall of the auxiliary flow channel 22 and the mounting groove 23 is removed, avoiding excessive abrasive adhering to the inner wall of the flow channel 22, which would affect subsequent processing.

[0049] like Figure 4 , Figure 5 , Figure 7 As shown, the moving part 32 includes a first electric push rod 321 fixedly connected to the sealing plate 15. The output end of the first electric push rod 321 is fixedly connected to a first motor 322. The output end of the first motor 322 is fixedly connected to a rotating rod 323. The rotating rod 323 passes through the sealing plate 15 and extends into the flow channel 22. The rotating rod 323 is connected to the auxiliary plate 31.

[0050] Specifically, when the auxiliary plate 31 needs to move, the first electric actuator 321 is activated, the output end of the first electric actuator 321 moves horizontally, the output end of the first electric actuator 321 drives the first motor 322 to move, the output end of the first motor 322 drives the rotating rod 323 to move horizontally, the rotating rod 323 drives the auxiliary plate 31 to move horizontally, and at the same time the first motor 322 is activated, the output end of the first motor 322 drives the rotating rod 323 to rotate, and the rotating rod 323 drives the auxiliary plate 31 to rotate.

[0051] The first electric actuator 321 can drive the auxiliary plate 31 to move horizontally, and the first motor 322 can drive the auxiliary plate 31 to rotate.

[0052] like Figure 4 , Figure 7As shown, the moving component 32 also includes a slot 324 formed in the rotating rod 323. A second electric actuator 325 is fixedly connected in the slot 324. A push plate 326 is fixedly connected to the output end of the second electric actuator 325. Hydraulic oil is provided in the cavity between the push plate 326 and the inner wall of the slot 324. A fixed sleeve 327 is fixedly sleeved on the rotating rod 323. An elastic telescopic rod 328 is fixedly connected to the fixed sleeve 327. A connecting groove 329 is formed in the rotating rod 323. One end of the connecting groove 329 communicates with the slot 324, and the other end of the connecting groove 329 communicates with the internal space of the elastic telescopic rod 328.

[0053] Specifically, when the auxiliary plate 31 needs to be in contact with the inner wall of the flow channel 22, the second electric actuator 325 is activated. The output end of the second electric actuator 325 drives the push plate 326 to move, so that the push plate 326 pushes the hydraulic oil into the connecting groove 329, and then through the connecting groove 329 into the elastic telescopic rod 328, so that the elastic telescopic rod 328 extends. The output end of the elastic telescopic rod 328 drives the auxiliary plate 31 to be in contact with the inner wall of the flow channel 22. When the auxiliary plate 31 needs to be reset, the second electric actuator 325 is reset. The elastic telescopic rod 328 resets under its own elastic force, and at the same time drives the auxiliary plate 31 to reset, while squeezing the hydraulic oil back into the slot 324.

[0054] like Figure 3 , Figure 6 , Figure 9 As shown, a movable component 16 is provided between the mounting frame 14 and the sealing plate 15. The movable component 16 includes two second motors 161 symmetrically fixedly connected to the mounting frame 14. The output end of the second motor 161 is fixedly connected to a lead screw 162. A connecting plate 163 is threadedly connected to the lead screw 162. The connecting plate 163 is fixedly connected to the sealing plate 15.

[0055] Specifically, when the sealing plate 15 needs to be moved during use, the second motor 161 is started. The output end of the second motor 161 drives the lead screw 162 to rotate, the lead screw 162 drives the connecting plate 163 to move, and the connecting plate 163 drives the sealing plate 15 to move.

[0056] like Figure 3 , Figure 8 , Figure 9 As shown, two limiting members 17 are symmetrically arranged on the lower side of the mounting frame 14. Each limiting member 17 includes a third electric push rod 171 fixedly connected to the mounting frame 14. An arc-shaped limiting plate 172 is fixedly connected to the bottom output end of the third electric push rod 171. The limiting plate 172 can abut against the upper side of the pump body 21.

[0057] Specifically, during use, after the pump body 21 is placed on the feed inlet 12, the third electric actuator 171 is activated. The output end of the third electric actuator 171 drives the limiting plate 172 to move downward. The limiting plate 172 abuts against the upper side of the pump body 21, and at the same time works with the feed inlet 12 to limit the pump body 21, preventing the pump body 21 from moving during the grinding process.

[0058] like Figure 3 , Figure 6 As shown, the base 11 has two symmetrical openings, and a collection box 18 is provided on the lower side of each opening.

[0059] Specifically, during use, after the abrasive flows out of the flow channel 22, it falls into the collection box 18 for collection.

[0060] Furthermore, the sealing plate 15 has a plurality of protrusions evenly arranged along the circumferential direction on one side near the pump body 21.

[0061] Specifically, when the sealing plate 15 blocks the opening of the flow channel 22, due to the setting of the protrusion, there is a gap between the sealing plate 15 and the pump body 21, which facilitates the discharge of the original gas in the pump body 21 when the abrasive is fed into the pump body 21, and avoids the gas from mixing into the abrasive and affecting the compactness of the abrasive.

[0062] In addition, the present invention also provides a dual-flow-channel pump body polishing process, comprising the following steps: S1: Clamp the pump body; S2: Connect one of the openings in the pump body to the abrasive flow device; S3: Block off other flow channels in the pump body; S4: Start the abrasive flow equipment and feed abrasive into the flow channel; S5: After the abrasive fills the pump body, the blocked flow channel is opened, allowing the abrasive to flow out.
