Description

Technical Field

[0002] A horizontal split centrifugal pump, also known as a split pump or a single-stage double-suction horizontal split centrifugal pump, is a high-efficiency and large-flow general-purpose centrifugal pump. The pump casing is divided into upper and lower parts along the horizontal center line. During maintenance, there is no need to disassemble the pipeline. Only by uncovering the upper pump cover can the internal impeller, shaft, etc. be maintained, greatly simplifying the maintenance process. The impeller has symmetric water inlet on both sides, eliminating the axial force, and the pump water efficiency is relatively high. The general processing steps of a split pump are blank processing, machining the joint surface and bottom surface, and then machining the bearing holes and inner boring holes. When machining the bearing holes and inner boring holes, first install and calibrate the tooling, connect the tool shank to the machine tool spindle, embed the positioning disc into the bearing holes of the pump body and pump cover, adjust the universal joint to make the center line of the tool bar coincide with the axis of the positioning disc, and use a micrometer to detect the runout of the tool bar before trial boring to ensure that the error is within the preset range. Since there are multiple inner holes in the split pump, multiple tool changes and alignment are required to complete the machining of the inner cavity.

The V-shaped positioning block and adjustable support on the bottom plate can be moved and adjusted according to different split pump bodies (D) for positioning cooperation with different models of split pump bodies (D). The split pump body (D) cooperates with the V-shaped positioning block on the bottom plate, and the adjustable support is used to adjust the split pump body (D). The V-shaped positioning block and the bottom plate, and the adjustable support and the bottom plate are both fastened by bolts.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: 1.

The cross plate moving towards the center position of the machine frame drives the sliding rod and the first positioning plate to move towards the center position of the machine frame. The first positioning plate closely adheres to the horizontally split centrifugal pump. At this time, the cross plate continues to move towards the center position of the machine frame to clamp and align the front and rear positions of the horizontally split centrifugal pump, which is beneficial to clamping and aligning the front and rear positions of the horizontally split centrifugal pump; The cross plate continues to move towards the center position of the machine frame to drive the extension rod to move towards the center position of the machine frame. The extension rod moving towards the center position of the machine frame drives the second air cylinder and the second positioning plate to move towards the center position of the machine frame. The output end of the second air cylinder extends to drive the second positioning plate to move towards the position of the horizontally split centrifugal pump. The second positioning plate clamps and aligns the left and right positions of the horizontally split centrifugal pump, which is beneficial to clamping and aligning the left and right positions of the horizontally split centrifugal pump and is beneficial to quickly aligning the horizontally split centrifugal pump to reach the standard position; 2. The output end of the second linear module moves downward to drive the centering clamping mechanism to move downward. The pressing plate of the centering clamping mechanism moves downward to closely adhere to the horizontally split centrifugal pump. The pressing plate continues to move downward, causing the second spring on the vertical rod on the upper side of the pressing plate to undergo elastic deformation, making the pressing plate further closely adhere to the horizontally split centrifugal pump. The third arc plate and the fourth arc plate of the sliding centering component of the centering clamping mechanism adhere to the horizontally split centrifugal pump to pre-center and clamp it. Through the cooperation of the pressing plate, the third arc plate, and the fourth arc plate, the horizontally split centrifugal pump is pre-centered and stably clamped, which is beneficial to pre-positioning, clamping, and conveying the horizontally split centrifugal pump; 3. The output end of the third linear module of the clamping device moves to the right to drive the clamped horizontally split centrifugal pump to move to the position of the processing device. The output end of the fifth linear module of the processing device moves downward to drive the driving motor, the cross bar, and the cutter head to move downward. The output shaft of the driving motor rotates to drive the cross bar to rotate. The cross bar rotates to drive the cutter head to rotate to process the horizontally split centrifugal pump. The output end of the fourth linear module moves back and forth to drive the fifth linear module to move back and forth.

The positioning device 4 further includes: a side positioning mechanism, and the side positioning mechanism is installed on the cross plate 44.

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

[0026] As Figure 2 , Figure 3 , Figure 4 , Figure 11As shown in the figure, the horizontal split centrifugal pump is moved to the position of the clamping device 5 by the transverse movement device 3. The horizontal split centrifugal pump is in the middle side position of the frame 1.

[0029] Embodiment 2: In some embodiments, as Figures 1 - 11 shown in the figure, as a preferred embodiment of the present invention, the conveying device 2 includes: a double-speed chain 21 and a jacking mechanism 22.

[0030] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 shown in the figure, the horizontal split centrifugal pump is placed on the conveying tray 23 of the double-speed chain 21 of the conveying device 2 for conveying. The jacking mechanism 22 jacks up the conveying tray 23 above it. The upward movement of the conveying tray 23 drives the horizontal split centrifugal pump to move upward.

[0032] The horizontal split centrifugal pump is placed on the conveying tray 23 of the double-speed chain 21 of the conveying device 2 for conveying. When the output end of the third cylinder 24 of the conveying device 2 extends, it drives the sliding bracket 26 to move towards the position of the horizontal split centrifugal pump under the restriction of the fixing block 25.

[0033] The transverse movement device 3 includes: a transverse movement bracket 31, a first linear module 32, and a second linear module 33.

[0036] As Figure 5 , Figure 6 , Figure 7 shown, when the output end of the second linear module 33 moves downward, it drives the centering and clamping mechanism to move downward. The pressing plate 36 of the centering and clamping mechanism moves downward and abuts against the horizontal split - case centrifugal pump. When the pressing plate 36 continues to move downward, the second spring 38 on the vertical rod 35 above the pressing plate 36 undergoes elastic deformation, causing the pressing plate 36 to further abut against the horizontal split - case centrifugal pump.

[0037] When the output end of the fifth cylinder 311 of the sliding centering assembly of the centering and clamping mechanism extends, it drives the connecting bracket 312 to move towards the horizontal split - case centrifugal pump. The movement of the connecting bracket 312 towards the horizontal split - case centrifugal pump drives both the third arc plate 313 and the fourth arc plate 314 to move towards the horizontal split - case centrifugal pump. The third arc plate 313 and the fourth arc plate 314 abut against the horizontal split - case centrifugal pump and pre - center and clamp it. Through the cooperation of the pressing plate 36, the third arc plate 313, and the fourth arc plate 314, the horizontal split - case 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 to drive the clamped horizontal split-case centrifugal pump upward, and the output end of the first linear module 32 moves to the right to drive the second linear module 33 to move to the right. Then, the output end of the second linear module 33 moves downward to convey the horizontal split-case centrifugal pump to the right to the clamping device 5.

[0041] The horizontal split-case centrifugal pump is conveyed to the position of the clamping device 5 through the transverse movement device 3. The output end of the fourth cylinder 53 of the clamping device 5 shortens to quickly fix the positioned horizontal split-case centrifugal pump. The output end of the sixth cylinder 59 shortens to drive the support plate 56 to move towards the position of the horizontal split-case centrifugal pump. The movement of the support plate 56 towards the position of the horizontal split-case centrifugal pump drives the first arc plate 57 and the second arc plate 58 to move towards the position of the horizontal split-case centrifugal pump. The first arc plate 57 and the second arc plate 58 perform secondary fixation on the positioned horizontal split-case centrifugal pump to prevent the position of the horizontal split-case centrifugal pump from shifting during subsequent processing.

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

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

[0044] The processing device 6 further includes: a driving motor 64, a cross bar 65, and a cutter head 66. The output ends of the two fifth linear modules 63 are fixedly installed with a driving motor 64. A cross bar 65 is fixedly installed between the output shafts of the two driving motors 64. A plurality of cutter heads 66 are fixedly installed on the cross bar 65.

[0045] As Figure 8 、 Figure 9 、 Figure 10 shown, the output end of the third linear module 51 of the clamping device 5 moves to the right to drive the horizontally split centrifugal pump being clamped 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 to drive the driving motor 64, the cross bar 65, and the cutter head 66 to move downward. The rotation of the output shaft of the driving motor 64 drives the cross bar 65 to rotate, and the rotation of the cross bar 65 drives the cutter head 66 to rotate to process the horizontally split centrifugal pump. The output end of the fourth linear module 61 moves back and forth to drive the fifth linear module 63 to move back and forth, and the fifth linear module 63 moves back and forth to drive the cutter head 66 to move back and forth to process the horizontally split centrifugal pump, which is beneficial to simultaneously process the two inner holes of the horizontally split centrifugal pump, improving the processing efficiency and the coaxiality of the two inner holes.

[0046] After the horizontally split centrifugal pump is processed, the output end of the third linear module 51 of the clamping device 5 moves to the left to drive the horizontally split centrifugal pump to move to the left. Then, the first linear module 32 and the second linear module 33 of the transverse movement device 3 cooperate to convey the processed horizontally split centrifugal pump to the tray support of the speed chain 21 and convey it away.
