Description

Technical Field

[0001] This invention relates to the field of multistage pump technology, specifically to a multistage pump core assembly device that is easy to position. Background Technology

[0002] Multistage centrifugal pumps are core devices that achieve high head by connecting impellers in series. They are widely used in high-pressure water supply, mine drainage, boiler feedwater and other scenarios. The core of the multistage pump is the core rotating component, which is mainly responsible for the step-by-step pressurization of the liquid. Its performance directly affects the pump's head, efficiency and stability. The liquid enters the first impeller from the inlet, is accelerated by centrifugal force and then enters the guide vane, which guides it to the next impeller for further pressurization. This process is repeated. Multiple impellers are connected in series along the pump shaft. Each impeller accelerates the liquid through centrifugal force, increasing the pressure step by step. Each impeller guides the liquid into the next impeller through guide vanes to increase the water pressure. The core of the multistage pump consists of a main shaft, retaining ring, outlet cover, guide vanes, impellers, spacers and flow guide cover.

The platform includes a clamping device, a driving device, a tilting table, and a vertical mounting platform for placing the inner cylinder. The clamping device includes several clamping components movably connected to the tilting table and locking members for fixing these components. The tilting table is rotatably connected to the vertical mounting platform. The output end of the driving device is connected to the tilting table to drive it to tilt. The vertical mounting platform includes a fixedly connected support platform and support legs. The platform has an opening at one end away from the tilting table, and the opening is U-shaped. The clamping assembly includes a first clamping ring and a second clamping ring. One end of the first clamping ring and one end of the second clamping ring are respectively hinged to the tilting table. The other end of the first clamping ring and the other end of the second clamping ring are connected by the locking member. Both the first clamping ring and the second clamping ring have a semi-circular arc structure and both have inner linings. Several support frames are provided on one side of the tilting table, and the first clamping ring and the second clamping ring are respectively hinged to the support frames.

[0019] Compared with the prior art, the beneficial effects of the present invention are: 1. The present invention uses an irregular frame of an adaptive clamping device to rotate on a support plate. The rotation of the irregular frame drives the rotation of a rotating frame, which in turn drives the rotation of a rotating rod. The rotation of the rotating rod drives the rotation of a guide wheel. The guide wheel and the rotating rod work together to clamp the guide vane, impeller, or shroud. The output shaft of the reduction motor rotates to drive the guide wheel to rotate. The rotation of the guide wheel drives the guide vane, impeller, or shroud clamped by the guide wheel to rotate. With the help of a vision system module to detect the direction of the main shaft, the impeller can be rotated to the same angle as the main shaft for installation. This is beneficial for adaptive clamping while adjusting the rotation direction to adapt to the installation position of the main shaft.

[0020] 2. The T-shaped sliding plate moves backward, causing the retaining ring to move backward. The retaining ring moves backward to the position of the limit block and is locked on the limit block to achieve the standard positioning of the retaining ring. The pneumatic gripper starts and drives the arc-shaped slider to move towards the retaining ring, clamping the retaining ring. The output end of the second cylinder shortens and drives the T-shaped sliding plate to move forward. The T-shaped sliding plate returns to its initial state. At this time, the retaining ring loses the support of the T-shaped sliding plate and is in a state where it is placed on the strip opening and clamped by the arc-shaped slider. The output end of the third cylinder extends and drives the pneumatic gripper, arc-shaped slider and retaining ring to move downward, putting the retaining ring on the main shaft, which is conducive to the precise feeding of retaining rings one by one.

[0021] 3. By stacking the water outlet cover, guide vane, impeller, and flow guide cover on the fixed rod, the output end of the second indexing plate rotates, driving the second disc to rotate. The rotation of the second disc drives the heightening block and the fixed rod to rotate, which facilitates moving the water outlet cover, guide vane, impeller, and flow guide cover one by one to the underside of the adaptive clamping device. This allows the water outlet cover, guide vane, impeller, and flow guide cover to be fed in a preset order, which is beneficial for feeding multiple parts one by one in a preset order.

The adaptive clamping device 5 includes: a connecting rod 51, a support plate 52, an irregular frame 53, a rotating frame 54, a rotating rod 55, a guide wheel 56, and a reduction motor 57. Multiple connecting rods 51 are fixedly installed on the main body feeding device 4, and the support plate... 52 is fixedly installed on the lower side of the connecting rod 51. The irregular frame 53 is rotatably connected to the support plate 52. Multiple rotating frames 54 are rotatably connected to the irregular frame 53 via rotating shafts. The end of the rotating rod 55 away from the center of the irregular frame 53 is hinged to the support plate 52. The middle side of the rotating rod 55 is slidably connected to the rotating frame 54. The guide wheel 56 is rotatably connected to the end of the rotating rod 55 near the center of the irregular frame 53 via rotating shafts.

The adaptive clamping device 5 also includes: a synchronous drive mechanism, which is installed on the support plate 52. The reduction motor 57 can be configured as a self-locking motor.

[0039] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the main shaft is inserted into the station of the multi-station installation device 2 via an external robotic arm or manually. The multi-station installation device 2 is activated, driving the main shaft to rotate to the position of the retaining ring feeding device 3. At this point, the main shaft can continue to be inserted to the next station of the multi-station installation device 2. The retaining ring feeding device 3 automatically feeds the retaining ring onto the main shaft. The multi-station installation device 2 is activated, driving the main shaft to rotate to the position of the main body feeding device 4. The main body feeding device 4 and the adaptive clamping device 5 cooperate to install the water outlet cover, guide vane, impeller, and flow guide cover onto the main shaft equipped with the retaining ring. The multi-station installation device 2 is activated, driving the main shaft to rotate to the position of the spacer feeding device 6. The spacer feeding device 6 automatically feeds the spacer onto the main shaft equipped with the retaining ring, water outlet cover, guide vane, impeller, and flow guide cover. The multi-station installation device 2 brings it back to the initial position. At this point, the screws can be tightened to lock it in place. The pump core is initially assembled. Usually, support bars need to be installed to further secure it before it can be used.

[0040] like Figure 5 , Figure 6As shown, the irregular frame 53 of the adaptive clamping device 5 rotates on the support plate 52. The rotation of the irregular frame 53 drives the rotating frame 54 to rotate, the rotation of the rotating frame 54 drives the rotating rod 55 to rotate, and the rotation of the rotating rod 55 drives the guide wheel 56 to rotate. The guide wheel 56 and the rotating rod 55 cooperate to clamp the guide vane, impeller or guide shield. The output shaft of the reduction motor 57 rotates to drive the guide wheel 56 to rotate. The rotation of the guide wheel 56 drives the guide vane, impeller or guide shield clamped by the guide wheel 56 to rotate. By setting the VS series vision system module produced by Keyence (China) Co., Ltd. on the main feeding device 4 above the adaptive clamping device 5 to detect the direction of the main shaft, the impeller can be installed by rotating it to the same angle as the main shaft. This is beneficial for adaptive clamping while adjusting the rotation direction to adapt to the installation position of the main shaft.

[0041] The synchronous drive mechanism includes: a rotary motor frame 58, a first motor 59, a threaded rod 510, and a threaded block 511. The rotary motor frame 58 is hinged to a support plate 52. The first motor 59 is fixedly mounted on the rotary motor frame 58. The threaded rod 510 is fixedly connected to the output shaft of the first motor 59. The threaded block 511 is hinged to a non-circular frame 53. The end of the threaded rod 510 away from the first motor 59 is threadedly connected to the threaded block 511.

[0042] like Figure 5 , Figure 6 As shown, the direction of the spindle is detected by installing a VS series vision system module manufactured by Keyence (China) Co., Ltd. on the main body feeding device 4 above the adaptive clamping device 5. The output shaft of the first motor 59 of the synchronous drive mechanism rotates to drive the threaded rod 510 to rotate. The rotation of the threaded rod 510 drives the threaded block 511 to move. The movement of the threaded block 511 drives the irregular frame 53 to rotate on the support plate 52. The rotation of the irregular frame 53 drives the rotating frame 54 to rotate. The rotation of the rotating frame 54 drives the rotating rod 55 to rotate. The rotation of the rotating rod 55 drives the guide wheel 56 to rotate. The guide wheel 56 and the rotating rod 55 cooperate to clamp the guide vane, impeller or guide shield. The output shaft of the reduction motor 57 rotates to drive the guide wheel 56 to rotate. The rotation of the guide wheel 56 drives the guide vane, impeller or guide shield clamped by the guide wheel 56 to rotate.

[0043] Example 2: In some embodiments, such as Figures 1-10 As shown, in a preferred embodiment of the present invention, the multi-station installation device 2 includes: a first indexing plate 21, a first disc 22, and a fixing frame 23.

The fixing frames 23 are fixedly installed on the first disc 22.

[0044] The first indexing plate 21 of the multi-station installation device 2 rotates, causing the first disc 22 to rotate, and the first disc 22 rotates, causing the fixed frame 23 to rotate.

[0045] like Figure 3 , Figure 4 , Figure 7 As shown, the multi-station installation device 2 further includes: a fixed arc plate 24, a sliding arc plate 25, and a first cylinder 26. The fixed arc plate 24 is fixedly installed on the fixed frame 23, and the sliding arc plate 25 is slidably connected to the fixed frame 23. The arc surfaces of the fixed arc plate 24 and the sliding arc plate 25 are arranged close to each other. The first cylinder 26 is fixedly installed on the fixed frame 23, and the output end of the first cylinder 26 is fixedly connected to the sliding arc plate 25.

[0046] The spindle is inserted between the fixed arc plate 24 and the sliding arc plate 25. The output end of the first cylinder 26 extends, causing the sliding arc plate 25 to move towards the fixed arc plate 24. The sliding arc plate 25 moves towards the fixed arc plate 24, clamping the spindle between the sliding arc plate 25 and the fixed arc plate 24. The output end of the first indexing plate 21 rotates, causing the first disc 22 to rotate. The rotation of the first disc 22 causes the fixed frame 23 to rotate. The rotation of the fixed frame 23 causes the fixed arc plate 24, the sliding arc plate 25 and the spindle to rotate. The rotation of the spindle switches between different work positions.

[0047] like Figure 4 , Figure 8 , Figure 9 As shown, the circlip feeding device 3 includes: a vibratory feeder 31, a stop block 32, a conveying channel 33, and a linear feeder 34.

[0049] The clamping ring feeding device 3 further includes: a feeding bracket 35, a horizontal plate 36, a baffle 37, a second cylinder 38, and a T-shaped sliding plate 39. The feeding bracket 35 is fixedly installed on the upper side of the cabinet 1, the horizontal plate 36 is fixedly installed on the upper side of the feeding bracket 35, the end of the conveying channel 33 away from the vibrating plate 31 is fixedly connected to the horizontal plate 36, the baffle 37 is fixedly installed on the horizontal plate 36, the baffle 37 is located at the end of the conveying channel 33 near the horizontal plate 36, the second cylinder 38 is fixedly installed on the horizontal plate 36, and the T-shaped sliding plate 39 is slidably connected to the horizontal plate 36, with one end of the T-shaped sliding plate 39 fixedly connected to the output end of the second cylinder 38.

[0050] The retaining rings are conveyed one by one through the conveying channel 33 to the T-shaped sliding plate 39 on the horizontal plate 36 of the feeding bracket 35. The baffle 37 is used to block the retaining rings so that they do not fall out of the T-shaped sliding plate 39. The output end of the second cylinder 38 extends and drives the T-shaped sliding plate 39 to move backward. The backward movement of the T-shaped sliding plate 39 drives the retaining rings to move backward, which is conducive to feeding the retaining rings one by one.

[0051] The clasp feeding device 3 further includes a vertical conveying mechanism, which is installed on the horizontal plate 36. The vertical conveying mechanism includes a limiting block 310, a vertical support 311, a third cylinder 312, and a pneumatic gripper 313. A strip-shaped opening is provided on the rear side of the horizontal plate 36. The limiting block 310 is fixedly installed on the upper side of the strip-shaped opening. The vertical support 311 is fixedly installed on the horizontal plate 36. The third cylinder 312 is fixedly installed on the vertical support 311. The pneumatic gripper 313 is fixedly connected to the output end of the third cylinder 312. The vertical conveying mechanism further includes a clamping assembly, which is installed on the limiting block 310.

[0052] The T-shaped sliding plate 39 moves backward, causing the retaining ring to move backward. The retaining ring moves backward to the position of the limiting block 310 and is locked on the limiting block 310 to achieve the standard positioning of the retaining ring.

[0053] like Figure 3 , Figure 4 , Figure 7 As shown, the clamping assembly includes: an arc-shaped slider 314, with arc-shaped sliders 314 slidably connected to both sides of the limiting block 310, and the upper side of the arc-shaped slider 314 fixedly connected to the output end of the pneumatic gripper 313. The spacer feeding device 6 and the retaining ring feeding device 3 have the same structure.

[0054] The T-shaped sliding plate 39 moves backward, causing the retaining ring to move backward. The retaining ring moves backward to the position of the limiting block 310 and is locked on the limiting block 310 to achieve the standard positioning of the retaining ring. The pneumatic gripper 313 starts, causing the arc-shaped slider 314 to move towards the retaining ring and clamp it. The output end of the second cylinder 38 shortens, causing the T-shaped sliding plate 39 to move forward. The T-shaped sliding plate 39 returns to its initial state. At this time, the retaining ring loses the support of the T-shaped sliding plate 39 and is in a state where it is placed on the strip opening and clamped by the arc-shaped slider 314. The output end of the third cylinder 312 extends, causing the pneumatic gripper 313, the arc-shaped slider 314 and the retaining ring to move downward, putting the retaining ring on the main shaft, which is conducive to the precise feeding of the retaining ring one by one.

[0055] The spacer feeding device 6 and the snap ring feeding device 3 have the same structure. The spacer feeding device 6 feeds each spacer precisely.

[0057] like Figure 4 , Figure 10 As shown, the output end of the second indexing plate 41 of the main feeding device 4 rotates, driving the second disc 42 to rotate. The rotation of the second disc 42 drives the heightening block 43 and the fixing rod 44 to rotate.

[0059] like Figure 1 , Figure 4 , Figure 10 As shown, the water outlet cover, guide vane, impeller, and flow guide cover are stacked on the fixed rod 44. The output end of the second indexing plate 41 rotates, driving the second disc 42 to rotate. The rotation of the second disc 42 drives the heightening block 43 and the fixed rod 44 to rotate, which facilitates the movement of the water outlet cover, guide vane, impeller, and flow guide cover to the underside of the adaptive clamping device 5 one by one. This allows the water outlet cover, guide vane, impeller, and flow guide cover to be loaded in a preset order, which is beneficial for loading multiple parts one by one in a preset order.

[0060] The water outlet cover, guide vanes, impeller, and flow guide cover are stacked on the fixed rod 44. The output end of the third linear module 411 moves backward, causing the lifting frame 412 to move backward. The lifting frame 412 moves backward to the position of the heightening block 43. At this time, the lifting frame 412 is located below the water outlet cover, guide vanes, impeller, or flow guide cover. The output end of the second linear module 410 moves upward, causing the third linear module 411 and the lifting frame 412 to move upward. The upward movement of the lifting frame 412 causes the water outlet cover, guide vanes, impeller, or flow guide cover to move upward. The output end of the first linear module 48 moves backward, causing the lifting mechanism 49 to move backward. The upward movement of the lifting mechanism 49 causes the water outlet cover, guide vanes, impeller, or flow guide cover to move upward. The adaptive clamping device 5 moves backward, and the lifting mechanism 49 moves downward, causing the adaptive clamping device 5 to move downward. The adaptive clamping device 5 clamps the water outlet cover, guide vane, impeller, or flow guide cover. The lifting mechanism 49 moves upward, and the output end of the first linear module 48 moves forward, causing the lifting mechanism 49 to move forward. The lifting mechanism 49 moves forward, causing the adaptive clamping device 5 to move forward. The lifting mechanism 49 moves downward, causing the adaptive clamping device 5 to move downward. The adaptive clamping device 5 places the water outlet cover, guide vane, impeller, or flow guide cover on the main shaft, realizing automatic rotation to install the main body (water outlet cover, guide vane, impeller, or flow guide cover) on the main shaft.
