[0002] After the impeller is cast, there is excess material at the edges of the impeller blades, which needs to be shaped to ensure the size and specifications of the impeller blades.

[0003] The traditional method involves clamping the impeller in a bench vise and manually shaping the blades using the vise's grip. Afterward, the vise is released, rotated at a certain angle, and then re-clamped to shape the blades of the next set of impellers.

[0004] The above-mentioned shaping process requires multiple clamping of the impeller, and the shaping is performed manually by holding the chuck and the shaping effect is judged manually, resulting in low shaping accuracy of the impeller blades.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0006] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an impeller blade shaping machine to solve the problem that the existing technology requires multiple clamping of the impeller during the shaping process, as well as hand-held clamping and manual judgment of the effect, resulting in low shaping accuracy of the impeller blades.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows:

[0008] A blade shaping machine for an impeller;

[0009] It includes: a base, a chuck that drives the impeller to rotate to a preset angle, a push rod that holds the impeller, a chuck for processing the impeller blades, and a detection device for detecting the shape of the impeller; wherein, the push rod is rotatably connected to the chuck; the chuck is movably mounted on the base; and the detection device is mounted on the base.

[0010] A further technical solution includes a fixture for placing the impeller; the clamp holds the fixture, and the push rod passes through the fixture to press against the impeller.

[0026] Figure 1 A schematic diagram of the blade shaping machine for the impeller according to an embodiment of the present invention is shown. Figure 2 A schematic diagram of the clamping disc according to an embodiment of the present invention is shown. (Combined with...) Figure 1and Figure 2 As shown, this utility model discloses a blade shaping machine for impellers.

[0027] The impeller blade shaping machine includes: a base 1 arranged in a left-right direction, a chuck 2 that drives the impeller to rotate to a preset angle, a push rod 3 that holds the impeller in place, a chuck 4 for processing the impeller blades, and a detection device 5 for detecting the shape of the impeller. The chuck 2 restricts the outer circumference of the impeller, and the push rod 3 holds the impeller from the left side. The chuck 4 is movably mounted on the base 1, moving closer to or away from the impeller. The push rod 3 is rotatably connected to the chuck 2. The detection device 5 is mounted on the base 1.

[0028] The chuck 2 holds the impeller, and the push rod 3 presses against the impeller, completely restricting its position. This prevents the impeller from shifting position after machining and rotation, ensuring the shaping accuracy of the impeller blades. When the chuck 2 drives the impeller to rotate a certain angle, the push rod 3 rotates synchronously by the same angle, avoiding friction between the push rod 3 and the impeller. At this time, the detection device 5 detects the impeller blades. The chuck 4 moves closer to the impeller and shapes the impeller blades. When the chuck 4 moves away from the impeller, the detection device 5 detects that the shaped impeller blades meet the requirements. Then, the chuck 2 drives the impeller to rotate a certain angle, and the chuck 4 moves closer to the impeller to shape the next impeller blade. This allows for the shaping of all impeller blades in a single installation, avoiding errors from multiple clamping operations. Simultaneously, the detection device 5's inspection and judgment of the impeller blades also ensures the machining accuracy of the shaping process.

[0029] The impeller blade shaping machine also includes a fixture 21 for placing the impeller. The fixture 21 is arranged around the edge of the impeller. The clamping plate 2 clamps and presses the fixture 21, which presses the edge of the impeller. The push rod 3 passes through the fixture 21 and pushes against the impeller. The clamping plate 2 increases the contact area of ​​the clamping plate 2 in holding the impeller. The push rod 3 pushes against the left end of the impeller, creating a rightward thrust on the impeller. The edge of the impeller can be closely fitted to the inner surface of the fixture 21, thus restricting the impeller without damaging it.

[0030] A support seat 11 is provided vertically on the base 1. A front seat 12 is provided on one side of the support seat 11, and the left end of the front seat 12 is connected to the right end of the support seat 11. A clamping plate 2 is provided on the right end of the front seat 12. Exemplarily, the clamping plate 2 is a pneumatic clamping plate. A power unit 13 is provided inside the front seat 12, and the power unit 13 drives the push rod 3 to press against the impeller. Exemplarily, the power unit 13 is a cylinder.

[0031] The power unit 13 drives the push rod 3 to move left and right, moving the push rod 3 closer to or further away from the impeller. When the push rod 3 is close to the impeller, it holds the impeller in place. When the push rod 3 is away from the impeller, it facilitates the removal of the impeller.

[0032] A counterweight 14 is provided on the other side of the support base 11, and the right end of the counterweight 14 is connected to the left end of the support base 11. The front seat 12 and the clamp 2 are located at the right end of the support base 11. The right end of the support base 11 bears a larger weight. The counterweight 14 balances the weight on both sides of the support base 11 to ensure the accuracy of the detected impeller blade shape.

[0033] A first bearing 15 is provided along the front seat 12, the support seat 11, and the counterweight seat 14. Exemplarily, the first bearing 15 is a rolling bearing. Exemplarily, there are two sets of first bearings 15. One set of first bearings 15 is located at the connection between the front seat 12 and the support seat 11, and the other set of first bearings 15 is located at the connection between the support seat 11 and the counterweight seat 14.

[0034] A connecting rod 16 is rotatably mounted inside the first bearing 15. Two sets of first bearings 15 ensure the stability of the rotation of the connecting rod 16. The connecting rod 16 is connected to the power device 13, and when the connecting rod 16 rotates, it drives the power device 13 to rotate simultaneously.

[0035] A second bearing 141 is provided at the left end of the counterweight 14. For example, the second bearing 141 is a plane bearing. A nut 17 is threaded onto the connecting rod 16, and the nut 17 presses against the second bearing 141. A rotary joint 18 is connected to the connecting rod 16, and an air pipe 19 is connected to the rotary joint 18, which is connected to an air source.

[0036] Gas is introduced into rotary joint 18 through gas pipe 19. Rotary joint 18 drives connecting rod 16 to rotate. Connecting rod 16 drives power device 13 and push rod 3 to rotate synchronously, so that push rod 3 also rotates when impeller rotates, avoiding friction between impeller and push rod 3.

[0037] A base plate 6 is horizontally mounted on the base 1. An adjusting component 61 is screwed into the base 1 and the base plate 6. Tightening the adjusting component 61 causes it to move up and down. The adjusting component 61 is located at the corner of the base plate 6. By adjusting the height of the corner of the base plate 6, the base plate 6 is adjusted to a horizontal position, thereby preventing the impeller from tilting and ensuring the accuracy of the detected impeller blade shape.

[0038] A movable module 7 is installed inside the base 1, and the movable module 7 is arranged along the moving direction of the chuck 4. The number of movable modules 7 is determined according to the number of moving directions of the chuck 4. If the chuck 4 needs to achieve linear movement, at least one set of movable modules 7 is required. If the chuck 4 needs to achieve planar movement, at least two sets of movable modules 7 are required. If the chuck 4 needs to achieve three-dimensional movement, at least three sets of movable modules 7 are required. One set of movable modules 7 in one moving direction is set at the drive end of another set of movable modules 7 in another moving direction, thereby realizing the movement of the chuck 4 in different directions.

[0039] A support 71 is provided at the drive end of the movable module 7 located at a high position. The position where the chuck 4 contacts the impeller blades is a contoured structure. The chuck 4 is distributed on the support 71 along both sides of the impeller blades. When the chuck 4 approaches the impeller, it simultaneously contacts both the upper and lower surfaces of the impeller blades, removing excess material from the impeller blades.

[0040] For example, the detection device 5 is an image sensor. The detection device 5 is connected to a display device 8, which displays the shape of the impeller blades. The shaping quality is determined by observing the shape of the impeller blades.
