Description
Technical Field
[0001] This invention relates to the field of welding equipment technology, and in particular to a welding equipment for the production and manufacturing of ceramic pumps. Background Technology
[0002] Impellers are core components of fluid machinery such as ceramic pumps, and impeller welding equipment is a key piece of equipment in impeller manufacturing. It can effectively improve welding quality and efficiency. Modern impeller welding equipment can complete its work efficiently and with high quality, which is inseparable from the support of the following key technologies: precision positioning and clamping, welding process optimization and control, and integrated quality inspection.
[0003] When welding impellers, existing welding equipment typically selects a mold corresponding to the impeller, places the impeller disc and blades on the mold in sequence, and then welds the connection between the impeller disc and blades. However, when welding impellers in this way, different molds need to be prepared for different models of impellers, which makes the impeller welding cost high. Moreover, when welding multiple different models of impellers, the molds need to be changed frequently, which makes the welding efficiency low. Summary of the Invention
[0004] In order to overcome the shortcomings mentioned in the background art, the present invention provides a welding equipment for manufacturing ceramic pumps.
[0005] The technical solution is as follows: A welding equipment for manufacturing ceramic pumps includes a frame, a welding torch and a rotating device, an output shaft of the rotating device fixedly connected to the frame body, and mounting blocks evenly spaced circumferentially distributed on the frame body. Each mounting block is rotatably connected to a rotating frame, and the rotating frame is equipped with a sliding frame. An adjusting component is rotatably connected to the frame body, and rotating shafts evenly spaced circumferentially distributed within the frame body are rotatably connected. The number of rotating shafts is equal to the number of mounting blocks. The rotating shafts are driven by a gear ring, and the rotating shafts are driven by a bevel gear set.
[0006] As an improvement to the above solution, the frame is fixedly connected to a mounting base, and the mounting base is rotatably connected to a worm gear and a worm. The worm gear and the worm mesh, and the worm gear and the adjusting component are driven by a gear ring.
[0007] As an improvement to the above solution, the rotating frame is slidably connected to the sliding frame, the sliding frame is rotatably connected to a first auxiliary frame, a first spring is provided between the sliding frame and the rotating frame, the sliding frame is slidably connected to a sliding member, the sliding member is rotatably connected to a second auxiliary frame, and a second spring is provided between the sliding member and the sliding frame.
[0008] As an improvement to the above solution, the rotating frame is fixedly connected to a first fixed shell, the first fixed shell is slidably connected to a positioning frame, a tension spring is provided between the positioning frame and the adjacent first fixed shell, and a clamping plate is fixedly connected to the positioning frame.
[0009] As an improvement to the above solution, the positioning frame is fixedly connected to a limiting piece, and the limiting piece and the first fixed shell mutually limit each other.
[0010] As an improvement to the above solution, the rotating frame is fixedly connected to a second fixed shell, the second fixed shell is slidably connected to a first sliding rod, the first sliding rod is fixedly connected to a fixed seat, the fixed seat is hinged to a rotating rod, the rotating rod is used to move the positioning frame, and a torsion spring is provided between the rotating rod and the adjacent fixed seat.
[0011] As an improvement to the above solution, the frame is fixedly connected to a third fixed shell that is circumferentially evenly distributed. The number of the third fixed shells is equal to the number of the mounting blocks. The third fixed shell is slidably connected to a second sliding rod. The third fixed shell and the second fixed shell are connected by a flexible hose. The frame is slidably connected to a control column. The control column is slidably connected to a connector. The connector is fixedly connected to the second sliding rod. Damping is provided between the connector and the control column.
[0012] As an improvement to the above solution, the frame is slidably connected with a first limiting post, and the control post is provided with two first limiting slots. The first limiting post is inserted into the first limiting slot of the control post to limit the control post. A third spring is provided between the first limiting post and the frame.
[0013] As an improvement to the above solution, the fixed base is slidably connected to a second limiting post, a fourth spring is provided between the second limiting post and the fixed base, and the rotating rod is provided with a second limiting groove that limits the movement of the second limiting post.
[0014] As an improvement to the above solution, the control column is fixedly connected to a transmission rope that is circumferentially evenly distributed. The number of transmission ropes is equal to the number of mounting blocks. The transmission ropes pass through the corresponding rotating frame. The sliding frame and the sliding member are respectively fixedly connected to a first elastic rope and a second elastic rope. Both the first elastic rope and the second elastic rope are fixedly connected to the corresponding transmission rope.
[0015] Compared with the prior art, the present invention has the following advantages: The present invention rotates the adjusting component, which drives the sliding frame to rotate, thereby changing the angle of the sliding frame. This changes the angle between the blade and the wheel on the frame when the blade is placed on the sliding frame, thus adapting to the welding of different types of blades, reducing the additional costs incurred by preparing multiple molds, and reducing the impact of mold replacement on welding efficiency.
[0016] By rotating the adjusting component through the worm gear and worm drive, the sliding frame is locked by utilizing the self-locking characteristics and high reduction ratio of the worm gear and worm, and the adjustment accuracy of the sliding frame angle is improved.
[0017] The blades are initially fixed by clamping plates, and then the blades are finally fixed by clamping the first and second auxiliary frames. This reduces the probability of blade displacement when the frame rotates, thereby improving the quality of impeller welding in this device. Attached Figure Description

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1
[0021] A welding equipment for manufacturing ceramic pumps, such as Figures 1-5 As shown, the assembly includes a frame 1, on which a welding torch 2 and a rotating device 3 are mounted. Both the welding torch 2 and the rotating device 3 are existing devices. The welding torch 2 can be repositioned as needed, and the rotating device 3 can drive the frame 4 to rotate. The welding torch 2 and the rotating device 3 work together to accommodate welding various shapes of gaps. The output shaft of the rotating device 3 is fixedly connected to the frame 4. The frame 4 is detachably fitted with circumferentially spaced mounting blocks 5. The figure shows four mounting blocks 5, but the number of mounting blocks 5 can be adjusted as needed to accommodate welding different numbers of blade impellers. Mounting block 5 is rotatably connected to rotating frame 6. Rotating frame 6 consists of a rotating shaft, a connecting part, and an L-shaped rod. Rotating frame 6 is equipped with sliding frame 7, which is used to support the blade. Frame body 4 is rotatably connected to adjusting component 8. Rotating shafts 9 are rotatably connected circumferentially evenly distributed inside frame body 4. The number of rotating shafts 9 is equal to the number of mounting blocks 5. Rotating shafts 9 and adjusting component 8 are driven by gear ring. Rotating shafts 9 and corresponding rotating frames 6 are driven by bevel gear set. The angle of all rotating frames 6 can be adjusted simultaneously by rotating adjusting component 8.
[0022] like Figure 2 and Figure 3 As shown, a mounting base 10 is fixedly connected to the outer side of the frame 4. The mounting base 10 is rotatably connected to a worm gear 11 and a worm 12. The worm gear 11 and the worm 12 mesh with each other. The worm gear 11 and the adjusting component 8 are driven by a gear ring. The high reduction ratio of the worm gear 11 and the worm 12 can improve the adjustment accuracy of the adjusting component 8 on the rotating frame 6. Furthermore, due to the self-locking characteristics of the worm gear 11 and the worm 12, the rotating frame 6 cannot drive the adjusting component 8 to rotate.
[0023] When using this device to weld the impeller of a ceramic pump, first place the device at the work site, then rotate the worm 12. The worm 12 drives the worm wheel 11 to rotate, and the worm wheel 11 drives the adjusting component 8 to rotate through the gear ring. The adjusting component 8 drives the four rotating shafts 9 to rotate through the gear ring. The rotating shafts 9 drive the adjacent rotating frame 6 to rotate through the bevel gear set. The rotating frame 6 drives the sliding frame 7 to rotate, thereby changing the angle between the rotating frame 6 and the sliding frame 7, thus adapting to the welding of blades at different angles. After adjustment, place the wheel disc on the frame 4, and place the blade tightly against the wheel disc on the sliding frame 7. Then welding can be carried out. During welding, the welding torch 2 and the rotating device 3 work simultaneously to change the position of the welding point, thereby completing the welding of the impeller. Example 2
[0024] Based on Example 1, such as Figure 2 and Figure 5 As shown, the rotating frame 6 and the sliding frame 7 are slidably connected, enabling the device to accommodate the welding of blades of various sizes. The sliding frame 7 is rotatably connected to a first auxiliary frame 701. A first spring 704 is provided between the sliding frame 7 and the rotating frame 6. The sliding frame 7 is slidably connected to a sliding member 702. The sliding member 702 is rotatably connected to a second auxiliary frame 703. Both the first auxiliary frame 701 and the second auxiliary frame 703 are used to hold the blades in place, thereby fixing the blades. Both the first auxiliary frame 701 and the second auxiliary frame 703 are Y-shaped and can rotate, allowing them to adapt to the curvature of the blade edges. A second spring 705 is provided between the sliding member 702 and the sliding frame 7. Both the first spring 704 and the second spring 705 are initially in a charged state.
[0025] like Figure 5 and Figure 6 As shown, the rotating frame 6 is fixedly connected to the first fixed shell 13, and the first fixed shell 13 is slidably connected to the positioning frame 14. A tension spring 1401 is provided between the positioning frame 14 and the adjacent first fixed shell 13. The tension spring 1401 is initially in a stretched state. The positioning frame 14 is fixedly connected to the clamping plate 15, which is used to clamp the blade, thereby initially fixing the blade. The positioning frame 14 is rotatably connected to the roller sleeve, which can reduce the friction between the blade and the positioning frame 14 when the blade slides.
[0026] like Figure 6 As shown, the positioning frame 14 is fixedly connected to the limiting piece 16, which is made of elastic material. The limiting piece 16 and the first fixed shell 13 limit each other, and the limiting piece 16 locks the first fixed shell 13 so that the positioning frame 14 cannot move into the first fixed shell 13.
[0027] like Figure 6 and Figure 7As shown, the rotating frame 6 is fixedly connected to the second fixed shell 17, the second fixed shell 17 is slidably connected to the first sliding rod 18, the first sliding rod 18 is fixedly connected to the fixed seat 19, the fixed seat 19 is hinged to the rotating rod 20, the rotating rod 20 is used to move the positioning frame 14, so that the positioning frame 14 moves outward from the first fixed shell 13, and a torsion spring 2001 is provided between the rotating rod 20 and the adjacent fixed seat 19.
[0028] like Figure 4 As shown, the frame 4 is fixedly connected to a third fixed shell 21 that is circumferentially evenly distributed. The number of third fixed shells 21 is equal to the number of mounting blocks 5. The third fixed shells 21 are slidably connected to a second sliding rod 22. The third fixed shells 21 and the second fixed shells 17 are connected by a hose. The third fixed shells 21, the second fixed shells 17, and the hose between them are all filled with a fluid for transmission, such as hydraulic oil. The frame 4 is slidably connected to a control column 23. The control column 23 is slidably connected to a connector 24. The connector 24 is fixedly connected to the second sliding rod 22. A damping is provided between the connector 24 and the control column 23, so that the control column 23 can drive the connector 24 to move through the damping. When the connector 24 can no longer move, the connector 24 will not affect the control column 23 from continuing to move.
[0029] like Figure 4 As shown, the frame 4 is slidably connected to a first limiting post 2301, which consists of a hemisphere and a cylinder. The control post 23 is provided with two first limiting slots. The first limiting post 2301 is inserted into the first limiting slot to limit the control post 23. A third spring 2302 is provided between the first limiting post 2301 and the frame 4. The third spring 2302 is always in a compressed state, so that the third spring 2302 provides sufficient resistance to the first limiting post 2301 on the control post 23, making the control post 23 unable to move.
[0030] like Figure 7 As shown, the fixed base 19 is slidably connected to a second limiting post 25, which consists of a hemisphere and a cylinder. A fourth spring 2501 is provided between the second limiting post 25 and the fixed base 19. The rotating rod 20 is provided with a second limiting groove that limits the second limiting post 25. The fourth spring 2501 is always in a compressed state, so that the fourth spring 2501 provides sufficient resistance to the second limiting post 25 on the rotating rod 20, thereby enabling the rotating rod 20 to move the positioning frame 14. After the positioning frame 14 can no longer move, the rotating rod 20 overcomes the resistance of the second limiting post 25 and rotates past the positioning frame 14 without affecting the movement of the positioning frame 14 into the first fixed shell 13.
[0031] like Figure 4 and Figure 5As shown, the control column 23 is fixedly connected to a circumferentially evenly spaced transmission rope 26. The transmission rope 26 does not lengthen when subjected to tension. The number of transmission ropes 26 is equal to the number of mounting blocks 5. A guide ring is fixedly connected inside the frame 4 to change the direction of the transmission rope 26. The transmission rope 26 passes through the corresponding rotating frame 6. The sliding frame 7 and the sliding member 702 are respectively fixedly connected to a first elastic rope 27 and a second elastic rope 28. The first elastic rope 27 and the second elastic rope 28 can lengthen when stretched. The elastic coefficient of the first elastic rope 27 and the second elastic rope 28 is greater than the elastic coefficient of the first spring 704 and the second spring 705, so that the first elastic rope 27 and the second elastic rope 28 can respectively pull the sliding frame 7 and the sliding member 702 to compress the first spring 704 and the second spring 705. The first elastic rope 27 and the second elastic rope 28 are both fixedly connected to the corresponding transmission rope 26.
[0032] Before welding the impeller, the control column 23 is moved upwards. The control column 23 presses the first limiting column 2301 to move it. The first limiting column 2301 compresses the third spring 2302. The control column 23 drives the connecting piece 24 to move upwards through damping. The connecting piece 24 drives the four second sliding rods 22 to move upwards. The second sliding rods 22 hydraulically drive the first sliding rod 18 to move outwards from the second fixed shell 17. The first sliding rod 18 drives the fixed seat 19 to move. The fixed seat 19 drives the rotating rod 20 to move. When the rotating rod 20 moves to contact the positioning frame 14, the positioning frame 14 can no longer move because it has reached its limit position. Therefore, the rotating rod 20 rotates and causes the torsion spring to move. 2001 stores power and simultaneously presses the second limiting post 25 to move, causing the second limiting post 25 to compress the fourth spring 2501. After the rotating rod 20 passes the positioning frame 14, the rotating rod 20 rotates under the action of the torsion spring 2001 until its second limiting groove is aligned with the second limiting post 25. At this time, the second limiting post 25, under the action of the fourth spring 2501, re-limits the rotating rod 20. At this time, the first sliding rod 18 moves to its limit position and stops moving, and the connecting piece 24 also stops moving. The control post 23 continues to move until its lower second limiting groove is aligned with the first limiting post 2301. The first limiting post 2301, under the action of the third spring 2302, limits the control post 23.
[0033] As the control column 23 moves upward, the transmission rope 26 gradually loosens, the sliding frame 7 moves under the action of the first spring 704, and the sliding member 702 moves under the action of the second spring 705. During the movement of the sliding frame 7 and the sliding member 702, the transmission rope 26 is kept taut by the first elastic rope 27 and the second elastic rope 28. Then the wheel can be placed on the frame 4, and then the blade is placed. When placing the blade, the blade presses against the limiting piece 16, the limiting piece 16 deforms and releases the limitation with the first fixed shell 13. Then the positioning frame 14 moves into the first fixed shell 13 under the action of the tension spring 1401. The positioning frame 14 drives the clamping plate 15 to move, so that the clamping plate 15 clamps the blade, thereby initially fixing the blade.
[0034] After the wheel and blades are all placed, move the control column 23 downwards to its original position. During this process, the control column 23 drives the rotating rod 20 back to its original position. The rotating rod 20 will first contact the positioning frame 14, and then the rotating rod 20 will rotate and pass over the positioning frame 14. At the same time, the control column 23 will drive the first elastic rope 27 and the second elastic rope 28 through the transmission rope 26 to pull the sliding frame 7 and the sliding member 702 to move. The sliding frame 7 and the sliding member 702 drive the first auxiliary frame 701 and the second auxiliary frame 703 to clamp the blades. During this clamping process, the second auxiliary frame 703 pushes the blades to move until they are close to the wheel. After that, the operation can proceed. Welding is completed. The control column 23 is moved upward. The control column 23 drives the rotating rod 20 to move. When the rotating rod 20 contacts the positioning frame 14, it will drive the positioning frame 14 to move. The positioning frame 14 stretches the tension spring 1401 until the limit plate 16 loses the obstruction of the first fixed shell 13 and returns to its original position. At this time, the positioning frame 14 also moves to the limit position and cannot move. The rotating rod 20 will pass the positioning frame 14 again. At this time, the control column 23 will also drive the first auxiliary frame 701 and the second auxiliary frame 703 to release the clamping of the blade. Then the welded impeller can be removed and a new impeller and blade can be placed for welding.
[0035] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present application. Therefore, the content of this specification should not be construed as a limitation of the present application.
