Description

Technical Field

[0001] This invention relates to the field of pump body processing technology, specifically to a processing device for the inner cavity of a horizontal split-case centrifugal pump. Background Technology

[0002] The horizontal split-case centrifugal pump, also known as a split-case pump or a single-stage double-suction split-case centrifugal pump, is a high-efficiency, high-flow-rate general-purpose centrifugal pump. The pump casing is divided into upper and lower parts along the horizontal centerline. During maintenance, there is no need to disassemble the pipeline; simply open the upper pump cover to maintain the internal impeller, shaft, etc., greatly simplifying the maintenance process. The impeller has symmetrical water intake on both sides, eliminating axial force and resulting in high pumping efficiency. The general machining steps for a split-case pump are: blank preparation, machining of the mating surface and bottom surface, followed by machining of the bearing holes and internal boring holes. When machining the bearing holes and internal boring holes, tooling is first installed and calibrated. The tool holder is connected to the machine tool spindle, and the positioning plate is embedded into the bearing holes of the pump body and pump cover. The universal joint is adjusted so that the centerline of the tool holder coincides with the axis of the positioning plate. Before trial boring, a dial indicator is used to check the runout of the tool holder to ensure that the error is within the preset range. Since there are multiple internal holes in the split-case pump, multiple tool changes and alignments are required to complete the machining of the internal cavity.

[0003] Chinese patent CN221561259U discloses a positioning and processing device for a split-case pump body (D). This device consists of a base plate, a V-shaped positioning block, an adjustable support, a support rod, a fastening screw, the split-case pump body (D), the fastening block, and a fastening nut. The V-shaped positioning block and the adjustable support on the base plate can be adjusted to accommodate different split-case pump bodies (D) for positioning with different models. The split-case pump body (D) engages with the V-shaped positioning block on the base plate, and the adjustable support adjusts the pump body (D). The V-shaped positioning block and the adjustable support are fastened to the base plate with bolts, while the support rod and the fastening screw are connected to the base plate with threads. The fastening screw and the fastening block are locked together with a nut.

[0004] However, the technical solution of this patent has the following problems: This patent cannot quickly align a horizontal split-case centrifugal pump to the standard position, nor can it perform pre-positioning clamping and conveying of the horizontal split-case centrifugal pump.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention uses the extension of the output end of the first cylinder of the positioning device to drive the horizontal plate to move towards the center position of the frame. The first guide rail and the first slider are used to limit the movement of the horizontal plate. The movement of the horizontal plate towards the center position of the frame drives the sliding rod and the first positioning plate to move towards the center position of the frame. The first positioning plate is in close contact with the horizontal split centrifugal pump. At this time, the horizontal plate continues to move towards the center position of the frame, clamping and aligning the front and rear positions of the horizontal split centrifugal pump, which is beneficial to clamping and aligning the front and rear positions of the horizontal split centrifugal pump. The horizontal plate continues to move towards the center position of the frame, driving the extension rod to move towards the center position of the frame. The movement of the extension rod towards the center position of the frame drives the second cylinder and the second positioning plate to move towards the center position of the frame. The extension end of the second cylinder extends, driving the second positioning plate to move towards the position of the horizontal split centrifugal pump. The second positioning plate clamps and aligns the left and right positions of the horizontal split centrifugal pump, which is beneficial to clamping and aligning the left and right positions of the horizontal split centrifugal pump and is beneficial to quickly aligning the horizontal split centrifugal pump to the standard position. 2. The downward movement of the output end of the second linear module drives the centering clamping mechanism to move downward. The pressure plate of the centering clamping mechanism moves downward and closely adheres to the horizontal split centrifugal pump. The pressure plate continues to move downward, causing the second spring on the upper vertical rod of the pressure plate to undergo elastic deformation, making the pressure plate even closer to the horizontal split centrifugal pump. The third and fourth arc plates of the sliding centering component of the centering clamping mechanism adhere to the horizontal split centrifugal pump and pre-center and clamp it. Through the cooperation of the pressure plate, the third arc plate and the fourth arc plate, the horizontal split centrifugal pump is pre-centered and stably clamped, which is beneficial for pre-positioning, clamping and conveying the horizontal split centrifugal pump. 3. The third linear module output end of the clamping device moves to the right, driving the clamped horizontal split centrifugal pump to the position of the processing device. The fifth linear module output end of the processing device moves downward, driving the drive motor, crossbar, and cutter head to move downward. The output shaft of the drive motor rotates, driving the crossbar to rotate, and the crossbar rotates, driving the cutter head to rotate, thus processing the horizontal split centrifugal pump. The fourth linear module output end moves back and forth, driving the fifth linear module to move back and forth, and the fifth linear module moves back and forth, driving the cutter head to move back and forth, thus processing the horizontal split centrifugal pump. This facilitates the simultaneous processing of the two inner holes of the horizontal split centrifugal pump, improving processing efficiency and the coaxiality of the two inner holes.

[0023] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0024] Example 1: In some examples, please refer to Figures 1-11A machining device for the inner cavity of a horizontal split-case centrifugal pump includes a frame 1, and further includes: a conveying device 2, a transverse moving device 3, a positioning device 4, a clamping device 5, and a machining device 6.

A plurality of sliding rods 45 are slidably connected to the horizontal plate 44. The first positioning plate 46 is fixedly installed on one end of the sliding rod 45 near the center of the frame 1. The first spring 47 is disposed on the sliding rod 45, with one end of the first spring 47 in close contact with the first positioning plate 46 and the other end in close contact with the horizontal plate 44. The first cylinder 48 is fixedly installed on the upper side of the positioning bracket 41, and the output end of the first cylinder 48 is fixedly connected to the horizontal plate 44. The positioning device 4 further includes a side positioning mechanism, which is installed on the horizontal plate 44.

[0025] like Figure 1 , Figure 2 , Figure 3 As shown, the conveying device 2 is used to convey the horizontal split-case centrifugal pump, and the transverse moving device 3 is used to clamp the horizontal split-case centrifugal pump on the conveying device 2 and move it laterally to place it on the positioning device 4. The positioning device 4 positions the horizontal split-case centrifugal pump to the standard position. The clamping device 5 quickly fixes and clamps the positioned horizontal split-case centrifugal pump and conveys it to the processing device 6. The processing device 6 processes the horizontal split-case centrifugal pump. After processing, the clamping device 5 and the transverse moving device 3 cooperate to convey the horizontal split-case centrifugal pump back to the conveying device 2, and then the conveying device 2 conveys the processed horizontal split-case centrifugal pump away.

[0026] like Figure 2 , Figure 3 , Figure 4 , Figure 11As shown, the horizontal split-case centrifugal pump is moved to the position of the clamping device 5 by the transverse moving device 3. The horizontal split-case centrifugal pump is in the middle position of the frame 1. The output end of the first cylinder 48 of the positioning device 4 extends, driving the horizontal plate 44 to move towards the center position of the frame 1. The first guide rail 42 and the first slider 43 are used to restrict the movement of the horizontal plate 44. The horizontal plate 44 moves towards the center position of the frame 1, driving the sliding rod 45 and the first positioning plate 46 to move towards the center position of the frame 1. The first positioning plate 46 is in close contact with the horizontal split-case centrifugal pump. At this time, the horizontal plate 44 continues to move towards the center position of the frame 1. The first spring 47 is compressed, improving the clamping effect of the first positioning plate 46. The first positioning plate 46 clamps and aligns the front and rear positions of the horizontal split-case centrifugal pump, which is beneficial for clamping and aligning the front and rear positions of the horizontal split-case centrifugal pump.

[0027] The side positioning mechanism includes: an extension rod 49, a second cylinder 410, and a second positioning plate 411. The extension rod 49 is fixedly installed on the horizontal plate 44, the second cylinder 410 is fixedly installed at the end of the extension plate away from the horizontal plate 44, and the second positioning plate 411 is fixedly installed at the output end of the second cylinder 410.

[0028] like Figure 11 As shown, the horizontal plate 44 continues to move towards the center of the frame 1, causing the extension rod 49 to move towards the center of the frame 1. The extension rod 49 moves towards the center of the frame 1, causing the second cylinder 410 and the second positioning plate 411 to move towards the center of the frame 1. The output end of the second cylinder 410 extends, causing the second positioning plate 411 to move towards the position of the horizontally split centrifugal pump. The second positioning plate 411 clamps and aligns the left and right positions of the horizontally split centrifugal pump, which is beneficial for clamping and aligning the left and right positions of the horizontally split centrifugal pump.

[0029] Example 2: In some embodiments, such as Figures 1-11 As shown, in a preferred embodiment of the present invention, the conveying device 2 includes: a double-speed chain 21 and a lifting mechanism 22. The double-speed chain 21 is disposed on the left side of the frame 1, and a plurality of conveying trays 23 are disposed on the double-speed chain 21. The lifting mechanism 22 is fixedly installed on the middle side of the double-speed chain 21, and the lifting mechanism 22 is configured as a cylinder lifting mechanism 22.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the horizontal split centrifugal pump is placed on the conveyor tray 23 of the double-speed chain 21 of the conveying device 2 for conveying. The lifting mechanism 22 lifts the conveyor tray 23 above it. The conveyor tray 23 moves upward, causing the horizontal split centrifugal pump to move upward. At this time, the lateral movement device 3 can clamp the horizontal split centrifugal pump and move it laterally to the position of the positioning device 4.

[0031] The conveying device 2 further includes: a third cylinder 24, a fixed block 25, and a sliding bracket 26. Two third cylinders 24 are respectively fixedly installed on the front and rear sides of the conveying tray 23. Multiple fixed blocks 25 are fixedly installed on the conveying tray 23. The sliding bracket 26 is slidably connected to the fixed block 25. The output end of the third cylinder 24 is fixedly connected to the sliding bracket 26.

[0032] The horizontally split centrifugal pump is placed on the conveying tray 23 of the double-speed chain 21 of the conveying device 2 for conveying. The output end of the third cylinder 24 of the conveying device 2 extends and drives the sliding bracket 26 to move towards the position of the horizontally split centrifugal pump under the restriction of the fixed block 25. The two sliding brackets 26 pre-clamp the horizontally split centrifugal pump on the conveying tray 23.

[0033] The transverse movement device 3 includes: a transverse movement bracket 31, a first linear module 32 and a second linear module 33. The transverse movement bracket 31 is fixedly installed on the upper side of the bracket of the speed-double chain 21, the first linear module 32 is fixedly installed on the transverse movement bracket 31, and the second linear module 33 is fixedly installed on the output end of the first linear module 32.

[0034] like Figure 5 As shown, the rightward movement output by the first linear module 32 of the transverse movement device 3 drives the second linear module 33 to move to the right.

[0035] The transverse movement device 3 further includes a centering clamping mechanism, which is installed on the output end of the second linear module 33. The centering clamping mechanism includes a shaped bracket 34, a vertical rod 35, a pressure plate 36, a limiting plate 37, and a second spring 38. The shaped bracket 34 is fixedly installed on the output end of the second linear module 33. Multiple vertical rods 35 are slidably connected to the shaped bracket 34. The pressure plate 36 is fixedly installed on the lower side of the vertical rod 35. Multiple limiting plates 37 are fixedly installed on the upper side of the vertical rod 35. The second spring 38 is disposed on the vertical rod 35. One end of the second spring 38 is in close contact with the shaped bracket 34, and the other end of the second spring 38 is in close contact with the pressure plate 36. The centering clamping assembly further includes a sliding centering assembly. Installed on the underside of the irregularly shaped bracket 34, the sliding centering assembly includes: a third guide rail 39, a third slider 310, a fifth cylinder 311, a connecting bracket 312, a third arc plate 313, and a fourth arc plate 314. The two third guide rails 39 are respectively fixedly installed on the front and rear sides of the irregularly shaped bracket 34. The third slider 310 is slidably connected to the third guide rail 39. The two fifth cylinders 311 are fixedly installed on the left and right sides of the irregularly shaped bracket 34. The connecting bracket 312 is fixedly installed on the third slider 310. The middle side of the connecting bracket 312 is fixedly connected to the output end of the fifth cylinder 311. Two third arc plates 313 are fixedly installed on the left side of the connecting bracket 312, and two fourth arc plates 314 are fixedly installed on the right side of the connecting bracket 312.

[0036] like Figure 5 , Figure 6 , Figure 7 As shown, the output end of the second linear module 33 moves downward, causing the centering clamping mechanism to move downward. The pressure plate 36 of the centering clamping mechanism moves downward and closely adheres to the horizontal split centrifugal pump. The pressure plate 36 continues to move downward, causing the second spring 38 on the vertical rod 35 on the upper side of the pressure plate 36 to undergo elastic deformation, making the pressure plate 36 even closer to the horizontal split centrifugal pump.

[0037] The extension of the output end of the fifth cylinder 311 of the sliding centering component of the centering clamping mechanism drives the connecting bracket 312 to move towards the horizontally split centrifugal pump. The movement of the connecting bracket 312 towards the horizontally split centrifugal pump drives the third arc plate 313 and the fourth arc plate 314 to move towards the horizontally split centrifugal pump. The third arc plate 313 and the fourth arc plate 314 are pressed against the horizontally split centrifugal pump to pre-center and clamp it. Through the cooperation of the pressure plate 36, the third arc plate 313 and the fourth arc plate 314, the horizontally split centrifugal pump is pre-centered and stably clamped.

[0038] After the horizontal split-case centrifugal pump is clamped, the output end of the second linear module 33 moves upward, causing the clamped horizontal split-case centrifugal pump to move upward. The output end of the first linear module 32 moves to the right, causing the second linear module 33 to move to the right. Then, the output end of the second linear module 33 moves downward, conveying the horizontal split-case centrifugal pump to the right to the clamping device 5.

[0039] Example 3: In some embodiments, such as Figures 1-11 As shown, in a preferred embodiment of the present invention, the clamping device 5 includes: a third linear module 51, a clamping bracket 52 and a fourth cylinder 53. The third linear module 51 is fixedly mounted on the frame 1, the clamping bracket 52 is fixedly mounted on the output end of the third linear module 51, and a plurality of the fourth cylinders 53 are fixedly mounted on the clamping bracket 52. The fourth cylinders 53 can be configured as rotary pressing cylinders.

[0040] like Figure 8 , Figure 9 As shown, the clamping device 5 further includes: a second guide rail 54, a second slider 55, a support plate 56, a first arc plate 57, a second arc plate 58, and a sixth cylinder 59. The two second guide rails 54 are fixedly installed on the output end of the third linear module 51. The second slider 55 is slidably connected to the second guide rail 54. The multiple support plates 56 are fixedly installed on the second slider 55. The first arc plate 57 is fixedly installed on the left side of the support plate 56, and the second arc plate 58 is fixedly installed on the right side of the support plate 56. The arc surfaces of the first arc plate 57 and the second arc plate 58 are both facing the center of the frame 1. The two sixth cylinders 59 are respectively fixedly installed on the output end of the third linear module 51, and the output end of the sixth cylinder 59 is fixedly connected to the support plate 56.

[0041] The horizontally split centrifugal pump is transported to the clamping device 5 via the transverse transfer device 3. The output end of the fourth cylinder 53 of the clamping device 5 shortens to quickly fix the positioned horizontally split centrifugal pump. The output end of the sixth cylinder 59 shortens to drive the support plate 56 to move toward the position of the horizontally split centrifugal pump. The movement of the support plate 56 toward the position of the horizontally split centrifugal pump drives the first arc plate 57 and the second arc plate 58 to move toward the position of the horizontally split centrifugal pump. The first arc plate 57 and the second arc plate 58 fix the positioned horizontally split centrifugal pump a second time to prevent the position of the horizontally split centrifugal pump from shifting during subsequent processing.

[0042] After the horizontal split centrifugal pump is fixed, the output end of the third linear module 51 of the clamping device 5 moves to the right, driving the clamped horizontal split centrifugal pump to the position of the processing device 6.

[0043] The processing device 6 includes: a fourth linear module 61, a vertical support 62, and a fifth linear module 63. The four fourth linear modules 61 are fixedly installed on the frame 1. Two of the fourth linear modules 61 are located on the front right side of the frame 1, and two of the fourth linear modules 61 are located on the rear right side of the frame 1. A vertical support 62 is fixedly installed at the output end of each fourth linear module 61, and a fifth linear module 63 is fixedly installed on each vertical support 62.

[0044] The processing device 6 further includes: a drive motor 64, a crossbar 65, and a cutting head 66. The output ends of the two fifth linear modules 63 are fixedly mounted with drive motors 64, and a crossbar 65 is fixedly mounted between the output shafts of the two drive motors 64. Multiple cutting heads 66 are fixedly mounted on the crossbar 65.

[0045] like Figure 8 , Figure 9 , Figure 10 As shown, the output end of the third linear module 51 of the clamping device 5 moves to the right, causing the clamped horizontal split centrifugal pump to move to the position of the processing device 6. The output end of the fifth linear module 63 of the processing device 6 moves downward, causing the drive motor 64, the crossbar 65 and the cutter head 66 to move downward. The output shaft of the drive motor 64 rotates, causing the crossbar 65 to rotate. The crossbar 65 rotates, causing the cutter head 66 to rotate, thus processing the horizontal split centrifugal pump. The output end of the fourth linear module 61 moves back and forth, causing the fifth linear module 63 to move back and forth. The fifth linear module 63 moves back and forth, causing the cutter head 66 to move back and forth, thus processing the horizontal split centrifugal pump. This facilitates the simultaneous processing of the two inner holes of the horizontal split centrifugal pump, improving processing efficiency and the coaxiality of the two inner holes.
