Description

Technical Field

[0001] This utility model belongs to the field of pump body processing technology, specifically relating to a multi-layer composite water pump body processing structure. Background Technology

[0002] Multistage composite pumps typically refer to multistage centrifugal pumps, which are centrifugal pumps that use multiple impellers connected in series. Each impeller progressively increases the pressure to achieve high-head delivery. The main characteristics of multistage centrifugal pumps include high head capacity, compact structure, high efficiency and energy saving, and adaptability to various media.

[0003] In the process of drilling holes in the pump body, the pump casing workpiece needs to be fixed first, and then processed. After processing, when the position of the pump casing needs to be adjusted, it needs to be unlocked first, and then adjusted. This is inconvenient to use. In addition, the position of the drilling motor is fixed during the processing. When drilling holes in different positions, the position of the pump casing workpiece needs to be adjusted repeatedly. To address this, we propose a multi-layer composite pump body processing structure. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-layer composite pump body processing structure to solve the problems mentioned in the background art, which require fixing the pump shell workpiece before processing during the pump body hole opening process. After the processing is completed, the pump shell position needs to be adjusted by first unlocking and then adjusting, which is inconvenient in use. In addition, the position of the hole opening motor is fixed during the processing process, and the position of the pump shell workpiece needs to be repeatedly adjusted when different positions of the hole are required.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-layer composite water pump body processing structure, including a base plate, a fixing frame fixedly installed at the rear side of the upper surface of the base plate, a lead screw threaded onto the fixing frame, a handle installed at the top of the lead screw, two fixing discs arranged above the base plate, the lower fixing disc fixedly installed on the upper surface of the base plate, and the upper fixing disc fixedly connected to the bottom end of the lead screw, the two fixing discs arranged opposite each other, each fixing disc having a rotating groove on its opposite surface, and a rotating disc rotatably installed in the rotating groove, and a movable frame fixedly installed at the front side of the upper surface of the base plate. The movable frame has a handrail welded to its side. A cylinder is fixedly mounted on the surface of the movable frame. The piston rod end of the cylinder extends into the movable frame and is fixedly mounted on a mounting base. A motor is fixedly mounted on the side of the mounting base. A threaded rod is rotatably mounted inside the mounting base. The output shaft of the motor is fixedly connected to one end of the threaded rod. A threaded plate is threaded onto the outer surface of the threaded rod. A connecting plate is fixedly mounted on the side of the threaded plate. The connecting plate extends out of the mounting base through a channel opened on the side of the mounting base and is fixedly mounted on the mounting plate. A perforated motor is detachably mounted on the side of the mounting plate. A perforated pin is fixedly mounted on the end of the output shaft of the perforated motor.

[0006] The above solution utilizes a fixed plate and a rotating plate in conjunction with a lead screw. The rotation of the lead screw allows the fixed plate at the top to move up and down. This, in turn, uses one fixed plate and one movable plate to stably clamp and fix the pump housing workpiece. The rotating plate can rotate on the fixed plate and is locked using an adjusting rod. This allows for positional adjustment of the pump housing workpiece while it is fixed, eliminating the need for repeated locking and unlocking operations and improving ease of use. Furthermore, a cylinder is used in conjunction with a motor. The cylinder allows for the up and down movement of the mounting base, which in turn allows for the up and down movement of the drilling motor. The motor allows for horizontal movement of the drilling motor. This movable design of the drilling motor enables multi-point drilling operations while the pump housing workpiece is in a fixed position.

[0007] In the above scheme, it should be noted that the cylinder, motor and the perforated motor are all electrically connected to an external power source.

[0008] In a preferred embodiment, a fixing plate is fixedly mounted on the surface of the rotating disk, an adjusting rod is slidably mounted on the fixing plate, an adjusting disk is fixedly mounted on one end of the adjusting rod, a spring is fixedly mounted between the adjusting disk and the fixing plate, a plurality of adjusting grooves are formed on the outer surface of the fixing disk, and the other end of the adjusting rod is used in conjunction with the adjusting grooves.

[0009] Using the above scheme, the adjusting rod and spring 1 work together. When the adjusting rod slides out of the adjusting groove, spring 1 deforms, and at this time the rotating disk unlocks and can rotate on the fixed disk. After the position is adjusted by rotation, the elastic force of spring 1 drives the adjusting rod to quickly reset and insert into the adjusting groove, thereby realizing the position rotation adjustment and locking.

[0010] In a preferred embodiment, an anti-slip pad is attached to the surface of the rotating disk, and two anti-slip pads are arranged opposite each other.

[0011] By adopting the above solution, the anti-slip pads can provide a good anti-slip effect when fixing the pump housing workpiece.

[0012] In a preferred embodiment, movable blocks are fixedly installed on both the left and right sides of the movable frame, and fixed rods are slidably installed on the movable blocks. Fixed blocks are fixedly installed at both ends of the fixed rods. The fixed blocks are fixedly installed on the sides of the base plate. A second spring is sleeved on the outside of the fixed rod, and the two ends of the second spring are fixedly connected to the opposite surfaces of the movable block and one of the fixed blocks, respectively.

[0013] By using the above solution, the fixed rod and the movable block work together to ensure the stable operation of the movable frame and avoid shaking. When the force is applied to drive the hole-opening motor on the movable frame to move the hole-opening needle close to the pump housing workpiece for hole-opening, the second spring is in a deformed state. After the force is released, the elastic force of the second spring can drive the movable frame to quickly reset the hole-opening motor and the hole-opening needle, thus improving the ease of operation.

[0014] In a preferred embodiment, a plurality of guide rods are fixedly installed on the inner wall of the movable frame, and the mounting base is slidably installed on the outer surface of the plurality of guide rods.

[0015] By adopting the above solution, the guide rod can support and guide the up and down movement of the mounting base, improve the stability of the movement, and prevent the mounting base from shaking. This ensures the smooth movement of the motor with holes on the mounting base.

[0016] In a preferred embodiment, a plurality of guide bars are fixedly installed on the inner wall of the mounting base, and a guide groove is provided at the end of the threaded plate, the guide bars and the guide groove being used in conjunction.

[0017] With the above solution, when the threaded rod rotates and drives the threaded plate to move, the threaded plate will slide on the surface of the guide bar through the guide groove. Therefore, the guide bar and the guide groove can be used to make the threaded plate move more smoothly and avoid shaking.

[0018] In a preferred embodiment, the perforated motor is threaded with several bolts, and the mounting plate has several threaded grooves on its side, with the bolts engaging with the threaded grooves.

[0019] By adopting the above solution, using bolts in conjunction with threaded grooves, the open-hole motor can be easily disassembled and installed. The threaded connection has good stability and is not easy to loosen.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] This multi-layer composite pump body processing structure uses a fixed plate and a rotating plate in conjunction with a lead screw. The rotation of the lead screw allows the fixed plate at the top to move up and down. The two fixed plates, one fixed and one movable, achieve stable clamping and fixing of the pump casing workpiece. The rotating plate can rotate on the fixed plate and be locked using an adjusting rod. This allows for rotational adjustment of the pump casing workpiece while it is fixed, eliminating the need for repeated locking and unlocking operations and improving ease of operation.

[0022] This multi-layer composite water pump body processing structure uses a cylinder in conjunction with a motor. The cylinder enables the mounting base to move up and down, which in turn enables the drilling motor to move up and down. The motor enables the drilling motor to move horizontally. The movable design of the drilling motor allows for multi-point drilling operations while the pump casing workpiece is in a fixed position. Attached Figure Description

[0028] Please see Figure 1-4This utility model provides a multi-layer composite water pump body processing structure, including a base plate 1. A fixing frame 2 is fixedly installed on the rear side of the upper surface of the base plate 1. A lead screw 3 is threaded onto the fixing frame 2, and a handle is installed at the top of the lead screw 3. Two fixing discs 4 are arranged above the base plate 1. The fixing disc 4 at the lower position is fixedly installed on the upper surface of the base plate 1, and the fixing disc 4 at the upper position is fixedly connected to the bottom end of the lead screw 3. The two fixing discs 4 are arranged opposite each other, and a rotating groove is opened on the opposite surface of the two fixing discs 4. A rotating disc 5 is rotatably installed in the rotating groove. A movable frame 6 is fixedly installed on the front side of the upper surface of the base plate 1. A handrail 7 is welded to the side of the movable frame 6. A cylinder 8 is fixedly mounted on the surface of the movable frame 6. The piston rod end of the cylinder 8 extends into the interior of the movable frame 6 and is fixedly mounted on a mounting base 9. A motor 10 is fixedly mounted on the side of the mounting base 9. A threaded rod 11 is rotatably mounted inside the mounting base 9. The output shaft of the motor 10 is fixedly connected to one end of the threaded rod 11. A threaded plate 12 is threadedly mounted on the outer surface of the threaded rod 11. A connecting plate 13 is fixedly mounted on the side of the threaded plate 12. The connecting plate 13 extends out of the mounting base 9 through a channel opened on the side of the mounting base 9 and is fixedly mounted on a mounting plate 14. A perforated motor 15 is detachably mounted on the side of the mounting plate 14. A perforated pin 16 is fixedly mounted on the end of the output shaft of the perforated motor 15.

[0029] By using a fixed plate 4 and a rotating plate 5 in conjunction with a lead screw 3, the rotation of the lead screw 3 allows the fixed plate 4 at the upper position to move up and down. This, in turn, uses one fixed plate 4 and the other movable plate 4 to achieve stable clamping and fixation of the pump housing workpiece. The rotating plate 5 can rotate on the fixed plate 4 and is locked by the adjusting rod 18. This allows for rotational adjustment of the pump housing workpiece while it is fixed, eliminating the need for repeated locking and unlocking operations and improving ease of use. By using a cylinder 8 in conjunction with a motor 10, the cylinder 8 allows the mounting base 9 to move up and down, which in turn allows the drilling motor 15 to move up and down. The motor 10 allows the drilling motor 15 to move horizontally. The movable design of the drilling motor 15 allows for multi-point drilling operations while the pump housing workpiece is in a fixed position.

[0030] A fixed plate 17 is fixedly installed on the surface of the rotating disk 5. An adjusting rod 18 is slidably installed on the fixed plate 17. An adjusting disk 19 is fixedly installed at one end of the adjusting rod 18. A spring 20 is fixedly installed between the adjusting disk 19 and the fixed plate 17. Several adjusting grooves are opened on the outer surface of the fixed disk 4. The other end of the adjusting rod 18 is used in conjunction with the adjusting groove. When the adjusting rod 18 slides out of the adjusting groove, the spring 20 deforms. At this time, the rotating disk 5 is unlocked and can rotate on the fixed disk 4. After the position is adjusted by rotation, the elastic force of the spring 20 drives the adjusting rod 18 to quickly return to the original position and insert into the adjusting groove, thereby realizing the position rotation adjustment and locking.

[0031] Anti-slip pads 21 are attached to the surface of the rotating disk 5. The two anti-slip pads 21 are arranged opposite each other. The anti-slip pads 21 can provide a good anti-slip effect when fixing the pump housing workpiece.

[0032] Movable blocks 24 are fixedly installed on both the left and right sides of the movable frame 6. Fixed rods 23 are slidably installed on the movable blocks 24. Fixed blocks 22 are fixedly installed at both ends of the fixed rods 23. The fixed blocks 22 are fixedly installed on the side of the base plate 1. A second spring 25 is sleeved on the outside of the fixed rods 23. The two ends of the second spring 25 are fixedly connected to the opposite surfaces of the movable blocks 24 and one of the fixed blocks 22, respectively. By using the fixed rods 23 and the movable blocks 24 together, the stable operation of the movable frame 6 can be ensured and the shaking phenomenon can be avoided. When the force is applied to drive the hole-opening motor 15 on the movable frame 6 to drive the hole-opening needle 16 to approach the pump housing workpiece for hole-opening operation, the second spring 25 is in a deformed state. After the force is released, the elastic force of the second spring 25 can drive the movable frame 6 to drive the hole-opening motor 15 and the hole-opening needle 16 to quickly return to their original positions, improving the convenience of operation.

[0033] Several guide rods 26 are fixedly installed on the inner wall of the movable frame 6. The mounting seat 9 is slidably installed on the outer surface of the guide rods 26. The guide rods 26 can support and guide the up and down movement of the mounting seat 9, improve the stability of the movement, and prevent the mounting seat 9 from shaking. This ensures that the movement of the perforated motor 15 on the mounting seat 9 is stable.

[0034] Several guide bars 27 are fixedly installed on the inner wall of the mounting base 9. The end of the threaded plate 12 is provided with a guide groove. The guide bars 27 and the guide groove work together. When the threaded rod 11 rotates to drive the threaded plate 12 to move, the threaded plate 12 will slide on the surface of the guide bar 27 through the guide groove. Therefore, the guide bar 27 and the guide groove can be used to make the threaded plate 12 move more smoothly and avoid shaking.

[0035] The perforated motor 15 has several bolts 28 threaded on it, and the side of the mounting plate 14 has several threaded grooves. The bolts 28 are used in conjunction with the threaded grooves. By using the bolts 28 in conjunction with the threaded grooves, the perforated motor 15 can be easily disassembled and assembled. The threaded connection has good stability and is not easy to loosen.

[0036] In use, the pump housing workpiece is placed on the surface of the rotating disk 5 at the lower position. Rotating the lead screw 3 drives the fixed disk 4 at the upper position to move the rotating disk 5 at the upper position downwards. When the upper and lower rotating disks 5 are in contact with the surface of the pump housing workpiece, the position of the pump housing workpiece is locked. Then, stop rotating the lead screw 3, and then push the movable frame 6 towards the pump housing workpiece through the handle frame 7. This will drive the perforation motor 15 towards the pump housing workpiece. At the same time, the cylinder 8 is started to drive the mounting base 9 to move the perforation motor 15 up and down, and the motor 10 is started to drive the perforation motor 15 horizontally. After adjusting the movement until the hole-opening needle 16 is aligned with the hole-opening point, stop the cylinder 8 and motor 10. Continue operating the movable frame 6 and start the hole-opening motor 15. The hole-opening needle 16 rotates to perform the hole-opening operation. At the same time, the movement of the movable frame 6 will drive the movable block 24 to move, causing the spring 25 to be compressed and deformed. Therefore, after the hole-opening is completed, release the handrail frame 7. The elastic force of the spring 25 can drive the movable frame 6 to move quickly to reset, thereby causing the hole-opening needle 16 to quickly disengage from the pump housing and reset the workpiece. Then, pull the adjusting plate 19 to drive the adjusting rod 18 to move and disengage from the adjusting groove. At this time, the rotating disk 5 is unlocked. The rotation of the rotating disk 5 drives the pump housing workpiece to rotate and adjust its position. After adjustment, the adjusting disk 19 is released. The elastic force of the spring 20 drives the adjusting rod 18 to reset and insert into the adjusting groove, so as to realize the position rotation adjustment of the pump housing workpiece under the premise of fixing. Then, the handrail frame 7 is operated again to drive the movable frame 6 to move. The cylinder 8 and the motor 10 are operated to adjust the position of the hole-punch motor 15 to perform operations at different points. When it is necessary to disassemble the hole-punch motor 15, the bolt 28 can be unscrewed to complete the disassembly.
