[0027] As Figures 1-6 shown, the present application is a kind of polishing device for impeller processing of pipeline pump, including substrate 1 and support plate 2, first rotating shaft 3 and second rotating shaft 35 are respectively arranged on support plate 2, one end of second rotating shaft 35 is connected with the output end of first motor 37 on support plate 2, the middle part of second rotating shaft 35 is provided with second gear 36, the middle part of first rotating shaft 3 is provided with first gear 33 engaged with second gear 36, and support assembly for supporting first rotating shaft 3 and second rotating shaft 35 is arranged between first rotating shaft 3 and second rotating shaft 35.

[0028] In work, the driving of first motor 37 drives second rotating shaft 35 to rotate, and at the same time, the rotation of second rotating shaft 35 drives two gears to rotate due to the engagement of second gear 36 and first gear 33, and then drives blocking ring 5 to rotate, because the impeller connected by screw 6 in blocking ring 5 makes the impeller rotate, and then the chamfer polishing of the impeller is completed.

[0029] The first rotating shaft 3 is provided with a reset assembly for driving the first gear 33 to reset; one end of the first rotating shaft 3 is provided with a stop ring 5, and the stop ring 5 is provided with a fixing assembly for fixing the impeller;

[0031] Preferably, the supporting assembly comprises a first circular ring 31, a U-shaped plate 32 and a second circular ring 34, the first gear 33 and the second gear 36 are located in the U-shaped plate 32, the two ends of the U-shaped plate 32 are sleeved on the second rotating shaft 35 through the second circular ring 34, and the middle position of the U-shaped plate 32 is sleeved on the first rotating shaft 3 through the first circular ring 31.

[0032] In this embodiment, the reset assembly comprises a spring 4 and a spring connecting rod 41, the supporting plate 2 is provided with the spring connecting rod 41, one end of the spring 4 is sleeved on the spring connecting rod 41, and the other end is sleeved on the first rotating shaft 3; during the movement of the stop ring 5, the stop ring 5 drives the first gear 33 to move and stretch the spring 4 through the connection of the first rotating shaft 3; since the first gear 33 is engaged with the second gear 36, the first gear 33 and the second gear 36 are always engaged during the movement of the first gear 33; since the chamfering range of the impeller is small, the movement of the stop ring 5 is also small, thereby the disengagement of the first gear 33 and the second gear 36 is small, and the teeth are always in the engaged state.

[0033] In this embodiment, the supporting plate 2 is provided with a sliding groove 21, the other end of the first rotating shaft 3 is in sliding connection with the sliding groove 21, so as to support the first rotating shaft 3, so that the first rotating shaft 3 can move and rotate, and one end of the second rotating shaft 35 is in rotating connection with the supporting plate 2.

[0035] In the embodiment, the polishing assembly further comprises a groove plate 7, a sliding plate 71, a driving shaft 73 and a cylinder 74, the groove plate 7 is installed on the motor connecting plate 81, the groove plate 7 is slidably provided with the sliding plate 71, one end of the sliding plate 71 is connected with the output end of the cylinder 74, the cylinder 74 is installed in the groove plate 7, the other end of the sliding plate 71 is connected with the polishing block 72 through the driving shaft 73;

[0036] The driving assembly comprises a second motor 82 and a telescopic rod 83, the second motor 82 is installed on the motor connecting plate 81, the output end of the second motor 82 is provided with the telescopic rod 83 connected with the sliding plate 71, one end of the driving shaft 73 penetrates through the sliding plate 71 and is fixedly connected with the telescopic rod 83;

[0037] By starting the second motor 82, the second motor 82 drives the polishing block 72 to rotate through the connection of the driving shaft 73 and the telescopic rod 83, while the polishing block 72 rotates, the cylinder 74 pushes forward to drive the polishing block 72 to push forward, thereby completing the chamfer polishing of the impeller; while the polishing block 72 pushes forward, one end of the L-shaped rod 75 moves forward and pushes the blocking ring 5 to move to one side, thereby stretching the spring 4, as the L-shaped rod 75 moves forward, the blocking ring 5 moves to one side, so that the impeller gradually contacts more and more of the polishing block 72, thereby completing the chamfer polishing of the impeller; after the polishing is completed, the cylinder 74 is retracted, so that the polishing block 72 moves away from the impeller, thereby the spring 4 is reset to drive the impeller to the initial position.

[0038] In the embodiment, one end of the polishing block 72 away from the driving shaft 73 is rotatably provided with an L-shaped rod 75, one end of the L-shaped rod 75 away from the polishing block 72 is slidably connected with the inner wall of the blocking ring 5; the inner wall of the blocking ring 5 is provided with a groove, one end of the L-shaped rod 75 is located in the groove to support the polishing block 72, and the L-shaped rod 75 moves forward along the groove under the pushing of the cylinder 74.

[0039] The working process is as follows:

[0040] By driving of the first motor 37, the second rotating shaft 35 starts to rotate. At the same time, the second gear 36 meshes with the first gear 33, causing the two gears to rotate together. This rotating process further drives the blocking ring 5 to start rotating, the blocking ring 5 is connected with the impeller through the screw rod 6 inside the blocking ring 5, so the impeller also starts to rotate, through such rotating mechanism, the chamfer polishing process of the impeller is completed. In this process, the first motor 37, the second rotating shaft 35, the second gear 36, the first gear 33, the blocking ring 5 and the screw rod 6 cooperate with each other, so that the impeller can smoothly perform chamfer polishing; this mechanism can efficiently complete the chamfer polishing task of the impeller, improving the working efficiency and polishing quality;

[0041] At the same time, the second motor 82 is started to guide the driving shaft 73 to be connected with the telescopic rod 83, in the process, the polishing block 72 starts to rotate; the rotation of the polishing block 72 and the forward pushing of the cylinder 74 are combined to make the whole system to normally carry out the chamfer polishing of the impeller; the extension of the telescopic rod 83 and the pushing of the polishing block 72 complete the chamfer polishing process of the impeller; at the same time, one end of the L-shaped rod 75 also starts to move forward, and the spring 4 becomes stretched by pushing the blocking ring 5; with the forward pushing of the L-shaped rod 75 and the movement of the blocking ring 5, the contact area of the impeller and the polishing block 72 gradually increases, which further strengthens the chamfer polishing effect of the impeller. When the required chamfer polishing effect is reached, the cylinder 74 starts to contract, so that the polishing block 72 and the impeller gradually separate. At this time, the spring 4 returns to its original state and brings the impeller back to the initial position. Through the above steps, the chamfer polishing process of the impeller is successfully completed.

[0042] It can be understood that the above embodiments are only exemplary embodiments for illustrating the principles of the present application, and the present application is not limited thereto. Various modifications and improvements can be made by those skilled in the art without departing from the spirit and essence of the present application, and these modifications and improvements are also considered to be within the protection scope of the present application.
