Description
Technical Field
[0001] This impeller outer edge saw belongs to the technical field of impeller outer edge saws, and relates to an impeller outer edge saw. Background Technology
[0002] The impeller outer edge saw is a mechanical device used for precise cutting of the outer edge of an impeller. It features high efficiency and high precision and is widely used in the uncoiling, straightening, shearing, and blanking of medium and heavy plates. This equipment can achieve fast and precise cutting of the impeller outer edge, thereby ensuring the accuracy of the cut impeller outer edge dimensions, reducing processing errors, and featuring a reasonable layout and simple and easy-to-understand operation. At the same time, the design of each component facilitates maintenance and upkeep, reducing operating costs and increasing the service life of the equipment.
[0003] For example, CN206492994U discloses an impeller outer edge saw, including a worktable and a vertical band saw blade mounted on the worktable. The worktable has a vertically upward-mounted positioning rod for fitting into the impeller's central shaft hole. The positioning rod slides along the feed direction of the band saw blade on the worktable. The worktable also has a positioning element for positioning the positioning rod. The positioning rod is rotatably connected to the impeller's central shaft hole. Through the sliding positioning rod and positioning element, different cutting sizes are adapted by first sliding the positioning rod, and then the positioning element fixes the positioning rod, fitting the impeller's central shaft hole onto the positioning rod, providing a cutting center for the impeller. Simply rotating the impeller allows for precise cutting of the impeller's outer edge, improving work efficiency and preventing dynamic imbalance during impeller rotation, reducing wear on the shaft and bearings, and increasing service life.
[0004] When using the above technical solution, although precise cutting of the outer edge of the impeller can be achieved simply by rotating the impeller, improving work efficiency and avoiding dynamic imbalance of the processed impeller during rotation, reducing wear on the shaft and bearings, and increasing service life, the above technical solution is not convenient for cleaning the metal debris generated during impeller edge cutting. This can easily lead to the accumulation of metal debris on the surface of the equipment. Currently, cleaning is usually done manually, which reduces the efficiency of impeller edge cutting.

It should be understood that the specific embodiments described herein are merely illustrative of the impeller outer edge saw and are not intended to limit the scope of this impeller outer edge saw.
[0021] It should be noted that, where there is no conflict, the embodiments of this impeller outer edge sawing machine and the features and technical solutions in the embodiments can be combined with each other.
[0022] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0023] Example 1
[0024] like Figures 1-5 As shown, it includes a support frame 1, a positioning plate 2 is fixedly connected to the rear side of the upper part of the support frame 1, a saw body 3 is fixedly connected to the lower part of the positioning plate 2, a positioning component is provided on the upper part of the support frame 1, and cleaning components are respectively provided on both sides of the inner cavity of the support frame 1.
[0025] The positioning assembly includes a first motor 4, a bidirectional lead screw 5 fixedly connected to the output shaft of the first motor 4, the bidirectional lead screw 5 passing through the support frame 1, threaded sleeves 6 being threadedly connected to the upper and lower parts of the surface of the bidirectional lead screw 5, a number of drive plates 7 being hingedly connected to the surface of the threaded sleeves 6, a fixed plate 8 being hingedly connected to one side of the drive plate 7, and a separator ring 9 being fixedly connected to the middle of the bidirectional lead screw 5.
[0026] A slip ring 10 is fixedly connected to the lower part of the first motor 4, a first gear 11 is fixedly connected to the surface of the first motor 4, a second gear 12 is meshed with the rear side of the first gear 11, a second motor 13 is provided at the lower part of the second gear 12, and the output shaft of the second motor 13 is fixedly connected to the second gear 12.
[0027] Connecting plates 14 are fixedly connected to both sides of the surface of the second motor 13, and the upper part of the connecting plate 14 is fixedly connected to the lower part of the support frame 1.
[0028] During operation: When it is necessary to saw the outer edge of the impeller, insert the inner shaft of the impeller into the positioning assembly, then start the first motor 4. The first motor 4 drives the double-acting lead screw 5 to rotate, and the double-acting lead screw 5 drives the two threaded sleeves 6 to move relative to each other. When the threaded sleeves 6 move, they can drive the drive plate 7 to move, and the drive plate 7 drives the fixed plate 8 to move. The fixed plate 8 then presses against the inner shaft of the impeller, thereby fixing the impeller as a whole. Then start the saw body 3, and use the saw body 3 to cut the outer edge of the impeller. When cutting the outer edge of the impeller... When the angle of the impeller needs to be adjusted after a cut is completed, the second motor 13 is started. The second motor 13 drives the second gear 12 to rotate, and the second gear 12 drives the first gear 11 to rotate. When the first gear 11 rotates, it can drive the first motor 4 to rotate. The first motor 4 is connected to the support frame 1 through a rotating joint. When the first motor 4 rotates, it can drive the double-acting screw 5 to rotate. The double-acting screw 5 drives the drive plate 7 and the fixed plate 8 to rotate. The fixed plate 8 then drives the impeller to rotate as a whole to adjust the position of the impeller.
[0029] Example 2
[0030] like Figures 2-5 As shown, the cleaning assembly includes two rotating plates 15, which are disposed on both sides of the inner cavity of the support frame 1. A rotating rod 16 is fixedly connected to the inner cavity of the rotating plate 15. The rear side of the rotating rod 16 is movably connected to the inner wall of the support frame 1 via a bearing. A worm gear 17 is fixedly connected to the front side of the rotating rod 16. A worm 18 is meshed with the lower part of the worm gear 17. A rotating shaft 19 is fixedly connected to the inner cavity of the worm 18. A rotating wheel 20 is fixedly connected to the left side of the rotating shaft 19. An electromagnet 21 is fixedly connected to the upper part of the rotating plate 15.
[0031] A collection box 22 is slidably connected to the front side of the lower part of the support frame 1, and a handle 23 is fixedly connected to the front side of the collection box 22. The collection box 22 is located at the lower part of the rotating plate 15.
[0032] A protective box 24 is fixedly connected to the bottom of the inner cavity of the support frame 1, and the first motor 4 and the second motor 13 are respectively installed in the protective box 24.
[0033] During operation: When the saw body 3 is cutting the impeller, the operator energizes the electromagnet 21, which then attracts the metal debris generated during cutting. After the impeller cutting is completed, the operator drives the rotating wheel 20, which in turn drives the rotating shaft 19 to rotate. The rotating shaft 19 then drives the worm gear 18 to rotate, which in turn drives the worm wheel 17 to rotate. When the worm wheel 17 rotates, it drives the rotating rod 16 to rotate. When the rotating rod 16 rotates, it drives the rotating plate 15 to rotate. The rotating plate 15 then drives the electromagnet 21 to rotate. When the electromagnet 21 is located above the collection box 22, the operator de-energizes the electromagnet 21, causing the metal debris to fall off and scatter into the collection box 22 for storage.
[0034] Working principle or operation: When it is necessary to saw the outer edge of the impeller, insert the inner shaft of the impeller into the positioning assembly, then start the first motor 4. The first motor 4 drives the double-acting lead screw 5 to rotate, and the double-acting lead screw 5 drives the two threaded sleeves 6 to move relative to each other. When the threaded sleeves 6 move, they can drive the drive plate 7 to move, and the drive plate 7 drives the fixed plate 8 to move. The fixed plate 8 then presses the inner shaft of the impeller, thereby fixing the impeller as a whole. Then start the saw body 3 to cut the outer edge of the impeller. When the cutting of one part of the outer edge of the impeller is completed and the angle of the impeller needs to be adjusted, start the second motor 13. The second motor 13 drives the second gear 12 to rotate, and the second gear 12 drives the first gear 11 to rotate. When the first gear 11 rotates, it can drive the first motor 4 to rotate. The first motor 4 is connected to the support frame 1 through a revolute joint, and the first motor 4 rotates... The bidirectional lead screw 5 can be driven to rotate, which in turn drives the drive plate 7 and the fixed plate 8 to rotate. The fixed plate 8 then drives the impeller to rotate as a whole to adjust the position of the impeller. When the saw body 3 cuts the impeller, the operator energizes the electromagnet 21, which then attracts the metal debris generated during cutting. After the impeller is cut, the operator drives the rotating wheel 20, which in turn drives the rotating shaft 19 to rotate. The rotating shaft 19 then drives the worm gear 18 to rotate, which in turn drives the worm wheel 17 to rotate. When the worm wheel 17 rotates, it drives the rotating rod 16 to rotate. When the rotating rod 16 rotates, it drives the rotating plate 15 to rotate, which in turn drives the electromagnet 21 to rotate. When the electromagnet 21 is located above the collection box 22, the operator de-energizes the electromagnet 21, causing the metal debris to fall off and scatter into the collection box 22 for storage.
