Description

Technical Field

[0001] This utility model relates to the field of mixed-flow pump parts processing technology, specifically to a milling device for mixed-flow pump parts. Background Technology

[0002] A mixed-flow pump is a fluid transport machine that combines the characteristics of centrifugal pumps and axial-flow pumps. Its working principle and structural characteristics make it suitable for applications requiring medium flow rate and head. When the impeller of a mixed-flow pump rotates, the liquid flows both axially (axial component) and radially (radial component). Its outlet water flow direction is between that of a centrifugal pump (radial outflow) and an axial-flow pump (axial outflow), hence the name "mixed-flow".

[0003] Mixed flow pumps are assembled from multiple parts. Many parts of mixed flow pumps are manufactured using milling equipment, such as impeller components, pump body and pump cover, shaft and shaft sleeve.

[0004] When machining the pump cover of a mixed-flow pump, a milling device is required to mill the mounting surface of the sealing ring that mates with the impeller to ensure sealing performance. At the same time, the plane and stop of the bearing housing mounting part also need to be milled to ensure the coaxiality of the bearing assembly. These milled parts require high milling accuracy, so different milling cutters need to be changed during milling to ensure milling accuracy. When performing multi-process machining of the pump cover of a mixed-flow pump, the existing milling device for mixed-flow pump parts requires frequent tool changes and re-clamping of parts, which not only increases auxiliary machining time, but also easily introduces errors due to multiple clamping, reducing the overall milling efficiency.

[0010] Preferably, each of the rotating rings has an incomplete toothed ring fixedly provided at one end near the clamping plate, and a support plate is rotatably provided between the fixed plates in the same group.

[0011] Preferably, a lifting plate is slidably provided at the bottom of the rotary table, and three connecting rods are fixedly provided on the outer circumference of the lifting plate.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] Please see Figure 1-5A milling device for mixed-flow pump parts, the technical solution proposed in this utility model includes a processing table 1 and three milling mechanisms 14 disposed on the processing table 1. A rotary table 2 is rotatably disposed on the processing table 1, and three sets of fixed plates 21 are fixedly disposed on the rotary table 2. Each fixed plate 21 is slidably disposed with a slide rod 24, and each end of the slide rod 24 is fixedly disposed with a clamping plate 25. A sliding column 26 is rotatably disposed at the end of each slide rod 24 away from the clamping plate 25. Multiple drive plates 27 are slidably disposed on the rotary table 2, and each sliding column 26 is slidably connected to each drive plate 27 in a one-to-one correspondence. The processing table 1 is fixedly disposed with... There is an abutment ring 15; the milling mechanism 14 is a milling robot arm in the prior art, and three milling mechanisms 14 are evenly fixedly arranged on the side of the processing table 1 away from the axis. The number of fixing plates 21 in each group is two. The clamping plate 25 is adapted to the clamping surface of the mixed flow pump cover. When the pump cover is placed between the two clamping plates 25 in the same group, the two slide rods 24 are pushed towards the pump cover, so that the pump cover is clamped by the two clamping plates 25. The sliding column 26 is T-shaped. The long arm end of the sliding column 26 is rotatably connected to the corresponding slide rod 24, and the short arm end of the sliding column 26 is slidably connected to the drive plate 27. The abutment ring 15 has The pump cover has an opening, and the opening of the abutment ring 15 has a bevel 16. In use, rotating the rotary table 2 causes the two corresponding fixed plates 21 to rotate to the opening of the abutment ring 15. Then, the pump cover is placed between the two clamping plates 25. The rotary table 2 continues to rotate, causing the fixed plates 21 to rotate. As the rotary table 2 rotates, the drive plate 27 abuts against the abutment ring 15. The bevel 16 on the abutment ring 15 abuts against the corresponding drive plate 27, causing the drive plate 27 to move closer to the axis of the rotary table 2. When the drive plate 27 moves, it pushes the sliding column 26 towards the clamping plate 25, thereby... Rod 24 pushes clamping plate 25 to clamp the pump cover. As the rotary table 2 rotates, when the clamped pump cover rotates to different milling mechanisms 14, the pump cover is milled by the milling mechanism 14. The milling cutters on each milling mechanism 14 have different precision, so different precision milling can be completed in one clamping. When the pump cover rotates to the opening of the abutment ring 15 again, the corresponding drive plate 27 is reset, thereby pulling the corresponding sliding column 26 away from the clamping plate 25, so that the clamping plate 25 releases the pump cover. At this time, the pump cover has completed multi-process milling. The milled pump cover is removed to complete the milling.

[0024] Specifically, each drive plate 27 has a first vertical groove 28, an inclined groove 29, and a second vertical groove 30 that are interconnected. Each sliding column 26 is slidably disposed in the interconnected first vertical groove 28, inclined groove 29, and second vertical groove 30. When the drive plate 27 is at the opening of the abutment ring 15, the sliding column 26 is in the first vertical groove 28. As the rotary table 2 rotates, when the drive plate 27 abuts against the inclined surface 16 of the abutment ring 15, the drive plate 27 moves toward the axis of the rotary table 2. During the movement, the sliding column 26 moves from the first vertical groove 28 through the inclined groove 29 to the second vertical groove 30. The inclined groove 29 and the second vertical groove 30 cause the sliding column 26 to move toward the clamping plate 25. When the drive plate 27 abuts against the inner ring of the abutment ring 15, the clamping plate 25 clamps the pump cover.

[0025] Specifically, multiple vertical plates 32 are fixedly installed on the rotary table 2. A spring 34 is fixedly installed between the end of each drive plate 27 away from the abutment ring 15 and each vertical plate 32. A moving rod 33 is fixedly installed between the end of each drive plate 27 away from the abutment ring 15. Each moving rod 33 is slidably connected to each vertical plate 32. When the drive plate 27 abuts against the inclined surface 16 and inner ring of the abutment ring 15, the drive plate 27 will move towards the vertical plate 32. At this time, the spring 34 is compressed, and the clamping plate 25 clamps the pump cover. When the drive plate 27 moves to the opening of the abutment ring 15, the spring 34 resets the drive plate 27, thereby moving the corresponding sliding column 26 from the second vertical groove 30 to the first vertical groove 28, and then the clamping plate 25 releases the pump cover.

[0026] Specifically, each fixed plate 21 is rotatably equipped with a rotating ring 22, and each sliding rod 24 is slidably disposed in each rotating ring 22. The rotary table 2 is provided with three chip removal grooves 101. The width of each chip removal groove 101 is the same as the distance between the two fixed plates 21 in the same group. When there are too many chips on the pump cover, the corresponding milling mechanism 14 is notified and the milling cutter is moved upward. At this time, the two rotating rings 22 on the fixed plate 21 in the same group are rotated. The rotating rings 22 drive the corresponding sliding rods 24 to rotate, which in turn drives the corresponding clamping plate 25 to rotate, so that the clamped pump cover is flipped 180 degrees. When the pump cover is flipped, the surface processed by the milling cutter is facing down, so that the chips on the pump cover fall off the pump cover and fall into the processing table 1 through the chip removal grooves 101. The chip removal grooves 101 can also be used for the pump cover to rotate.

[0027] Specifically, each rotating ring 22 has an incomplete toothed ring 23 fixedly installed at one end near the clamping plate 25, and a support plate 31 is rotatably installed between the fixed plates 21 in the same group; the support plate 31 is concave, and each sliding rod 24 is slidably connected to each incomplete toothed ring 23 in a one-to-one correspondence. The two ends of the support plate 31 between the fixed plates 21 in the same group are fixedly connected to the lower ends of the corresponding incomplete toothed rings 23. When the two drive plates 27 in the same group are aligned with the opening of the abutment ring 15, the pump cover is placed on the support plate 31 and supported by the support plate 31. When it is necessary to remove the chips on the pump cover, the incomplete toothed rings 23 on both sides of the pump cover are rotated at the same time, which can drive the pump cover to flip over and make the chips on the pump cover fall off.

[0028] Specifically, a lifting plate 6 is slidably mounted on the bottom of the rotary table 2. Three connecting rods 7 are fixedly mounted on the outer circumference of the lifting plate 6. A lifting block 8 is fixedly mounted on the end of each connecting rod 7 away from the lifting plate 6. A toothed plate 10 that meshes with the incomplete toothed ring 23 is fixedly mounted on both ends of each lifting block 8. There are three milling mechanisms 14 on the machining table 1. When there are too many chips on the pump cover, the three milling mechanisms 14 are stopped and the milling cutter moves upward. Then the lifting plate 6 moves downward. The lifting plate 6 drives the three lifting blocks 8 to move downward through the connecting rods 7. When the lifting blocks 8 move downward... The toothed plates 10 that mesh with the incomplete toothed rings 23 move downwards, thereby driving the incomplete toothed rings 23 to rotate, which in turn drives the support plates 31 to flip and remove the chips on the pump cover. As the pump cover rotates from one milling mechanism 14 to the next, the lifting plate 6 moves downwards, which can drive the pump cover to flip, so that the chips on the pump cover that has completed the previous step fall off. After the pump cover flips 180 degrees, the lifting plate 6 moves upwards again, so that the pump cover is reset, and so that when the pump cover enters the next milling mechanism 14, there are no chips on its surface to be machined.

[0029] Specifically, each lifting block 8 is fixedly equipped with multiple abutment plates 9, the rotary table 2 is fixedly equipped with a hydraulic cylinder 13, and the lifting plate 6 is fixedly equipped with multiple connecting columns 11. A fixing frame 12 is fixedly installed at the end of the hydraulic cylinder 13 furthest from the rotary table 2, and each connecting column 11 is fixedly connected to the fixing frame 12. A support frame 3 is fixedly installed at the bottom of the rotary table 2, and a servo motor 4 is fixedly installed on the support frame 3. A connecting shaft 5 is fixedly installed at the output end of the servo motor 4, and the end of the connecting shaft 5 furthest from the servo motor 4 is fixedly connected to the rotary table 2. The lifting plate 6 is slidably connected to the connecting shaft 5. The servo motor 4 drives the rotary table 2 to rotate, and the lifting plate 6 rotates together with the rotary table 2. The moving end of the hydraulic cylinder 13 is fixedly connected to the fixed frame 12. The hydraulic cylinder 13 drives the fixed frame 12 to move up and down, thereby driving the lifting plate 6 to move up and down through each connecting column 11. The end of each abutment plate 9 away from the lifting block 8 is arc-shaped. The side of each lifting block 8 near the rotary table 2 is set as a slope 16. The lower end of each toothed plate 10 has no teeth. Each rotating ring 22 is connected to the corresponding... Each of the fixed plates 21 has a certain damping. Each lifting block 8 is aligned with each chip removal groove 101. In the initial state, the hydraulic cylinder 13 drives the lifting plate 6 to move upward so that the abutment plate 9 on each lifting block 8 abuts against the bottom surface of the support plate 31, so that the support plate 31 will not rotate. At this time, the teeth on each toothed plate 10 are all on the upper side of the incomplete toothed ring 23. When each support plate 31 is below the corresponding milling mechanism 14, the bottom of the support plate 31 is supported by the abutment plate 9, which can protect the pump cover during the milling mechanism 14. To maintain the stability of the support plate 31, when it is necessary to remove the chips from the pump cover, the hydraulic cylinder 13 drives the lifting plate 6 to move down. When the lifting plate 6 moves down, it drives each toothed plate 10 to move down. After each lifting block 8 moves down a certain distance, the teeth on each toothed plate 10 abut and mesh with the corresponding incomplete toothed ring 23. The lifting plate 6 continues to move down, and the toothed plate 10 drives the support plate 31 and the clamping plate 25 to flip, so that the chips on the pump cover fall from the chip discharge groove 101 onto the lifting block 8. At this time, the chips fall off the lifting block 8 through the inclined surface 16 of the lifting block 8.
