[0027] It is understandable that, referring to Figure 1 , Figures 3 to 5 The dynamic balancing test device of the utility model comprises a test mechanism 100 and a feeding mechanism 200. The test mechanism 100 comprises a workbench 110 and a detection assembly 120. The workbench 110 is provided with a rotating shaft 111. The rotating shaft 111 is used to connect the impeller. The detection assembly 120 is used to detect the rotating shaft 111. The feeding mechanism 200 comprises a moving assembly 210 and a clamping assembly 220. The moving assembly 210 is used to drive the clamping assembly 220 to move in the horizontal direction and the vertical direction. Component 220 includes a first driving component 221, a connecting plate 222 and a plurality of clamping blocks 223. The plurality of clamping blocks 223 are arranged at intervals along the circumference of the connecting plate 222. The clamping blocks 223 are provided with a slide groove 224 in the vertical direction. The slide groove 224 is penetrated by a baffle 225. The connecting plate 222 is rotatably connected with a first bolt 226. The baffle 225 and the first bolt 226 are threadedly connected. The first driving component 221 is used to drive the plurality of clamping blocks 223 to approach each other so that the clamping blocks 223 can abut against the impeller.

[0028] The rotating shaft 111 is rotatably connected to the workbench 110, and the impeller is installed on the rotating shaft 111. The rotating shaft 111 can drive the impeller to rotate. The rotating shaft 111 can be detected by the detection component 120 to detect the dynamic balance parameters of the impeller. The moving component 210 can drive the clamping component 220 to move in the horizontal direction and the vertical direction, so that the clamping component 220 can move in the vertical plane. A plurality of clamping blocks 223 are arranged at intervals along the circumference of the connecting plate 222. The clamping blocks 223 are provided with a slide groove 224 in the vertical direction. The baffle 225 is arranged in the horizontal direction, and the baffle 225 is slidably connected to the slide groove 224, so that the baffle 225 can move in the vertical direction. The connecting plate 222 is driven to move above the impeller by the moving component 210, and then driven to move toward the direction close to the rotating shaft 111, so that the first driving member 221 drives the multiple clamping blocks 223 to approach each other, so that the clamping blocks 223 abut against the impeller, and the baffle 225 is located below the impeller. Then, the moving component 210 drives the connecting plate 222 to rise, so that the baffle 225 can remove the impeller from the rotating shaft 111, thereby realizing automatic unloading of the impeller, improving the unloading efficiency of the impeller, preventing damage to the rotating shaft 111, and improving reliability.

[0029] In addition, the first bolt 226 is rotatably connected to the connecting plate 222, and the first bolt 226 is threadedly connected to the baffle 225. By rotating the first bolt 226, the baffle 225 can move along the length direction of the slide groove 224, and the distance between the baffle 225 and the connecting plate 222 can be adjusted, so that the impeller can be conveniently accommodated between the connecting plate 222 and the baffle 225. It can adapt to the size of the impeller, improve applicability, reduce the position shaking of the impeller during the unloading process, reduce the possibility of collision damage between the impeller and the connecting plate 222, and improve reliability.

[0030] Among them, the detection component 120 is a prior art, and the detection component 120 can be a dynamic balancing tester, a dynamic balancing testing machine, etc., which can detect the dynamic balancing parameters of the rotating shaft 111, and will not be described in detail here.

[0031] It should be noted that the first bolt 226 is fixedly connected to two limit plates 229 , which are arranged at intervals along the axial direction of the first bolt 226 and are located on both sides of the connecting plate 222 so that the first bolt 226 can rotate smoothly on the connecting plate 222 .

[0032] It can be understood that the connecting plate 222 is provided with a plurality of guide grooves, and the guide grooves correspond to the clamping blocks 223 one by one, and the clamping blocks 223 and the first bolts 226 can slide smoothly in the guide grooves.

[0033] In addition, the first driving member 221 may be a pneumatic clamp or an electric clamp, which will not be described in detail here.

[0034] It is understandable that, referring to Figure 1 and Figure 5 The end of the baffle 225 away from the clamping block 223 is connected to a guide plate 227, and the guide plate 227 is arranged obliquely in a direction away from the connecting plate 222. The guide plate 227 is connected to the end of the baffle 225 away from the clamping block 223, and the guide plate 227 is arranged obliquely in a direction away from the connecting plate 222, so that when the first driving member 221 drives the plurality of clamping blocks 223 to approach each other, the impeller can abut against the guide plate 227, thereby guiding the impeller to slide above the baffle 225, making it convenient for the baffle 225 to remove the impeller from the rotating shaft 111, reducing the damage of the baffle 225 to the impeller, and improving the reliability of the unloading mechanism 200.

[0035] It should be noted that the impeller may be stuck in the axial direction of the rotating shaft 111 due to manufacturing errors, resulting in a deviation in the installation position of the impeller on the rotating shaft 111. By setting the guide plate 227 to be inclined, when the first driving member 221 drives the multiple clamping blocks 223 to approach each other, the guide plate 227 can abut against the impeller, thereby smoothly driving the impeller to move along the axial direction of the rotating shaft 111, and then the impeller can be easily removed from the rotating shaft 111, avoiding the baffle 225 from scratching the impeller, thereby improving reliability.

[0036] Specifically, refer to Figure 5 , there is a smooth transition between the baffle plate 225 and the guide plate 227. By setting a smooth transition between the baffle plate 225 and the guide plate 227, when the first driving member 221 drives the plurality of clamping blocks 223 to approach each other, the impeller can slide from the guide plate 227 to the baffle plate 225, thereby preventing the impeller from being damaged at the connection between the baffle plate 225 and the guide plate 227, and improving the material feeding stability of the impeller.

[0037] It should be noted that the baffle plate 225 and the guide plate 227 may be rounded to make the connection between the baffle plate 225 and the guide plate 227 smooth.

The cross-sectional shape of the sliding rod 228 is rectangular, and the opposite sides of the sliding rod 228 can abut against the opposite sides of the slide groove 224. The sliding rod 228 is slidably connected to the slide groove 224. By setting the cross-sectional shape of the sliding rod 228 to be rectangular, the opposite sides of the sliding rod 228 can respectively abut against the opposite sides of the slide groove 224, so that the sliding rod 228 can smoothly move along the length of the slide groove 224, avoiding the position shaking of the sliding rod 228, preventing the baffle 225 from rotating, and improving the position stability of the baffle 225.

[0039] It is understandable that, referring to Figure 1 and Figure 3The moving assembly 210 includes a support frame 211, a second driving member 212 and a third driving member 213. The support frame 211 is slidably connected to the workbench 110. The second driving member 212 is used to drive the support frame 211 to move in a horizontal direction. The third driving member 213 is arranged on the support frame 211, and the clamping assembly 220 is arranged on the movable end of the third driving member 213. The support frame 211 is slidably connected to the workbench 110, the fixed end of the second driving member 212 is fixedly connected to the workbench 110, and the movable end of the second driving member 212 is fixedly connected to the support frame 211, so that the second driving member 212 can drive the support frame 211 to move in the horizontal direction, the fixed end of the third driving member 213 is fixedly connected to the support frame 211, and the clamping assembly 220 is connected to the movable end of the third driving member 213, so that the third driving member 213 can drive the clamping assembly 220 to move in the vertical direction. The second driving member 212 and the third driving member 213 cooperate to drive the clamping assembly 220 to move in the vertical plane, thereby improving the movement flexibility of the clamping assembly 220.

[0040] It should be noted that the second driving member 212 and the third driving member 213 can both be linear cylinders, electric push rods or linear slide modules, etc., which are not described in detail here.

[0041] Specifically, refer to Figure 1 and Figure 2 The third driving member 213 is fixedly connected with an adjustment seat 214, and the adjustment seat 214 is provided with an adjustment slot 215 in the vertical direction, and the adjustment slot 215 is penetrated with a second bolt 216, and the second bolt 216 is threadedly connected to the support frame 211. The adjustment seat 214 is fixedly connected with the third driving member 213, and the adjustment seat 214 is provided with an adjustment slot 215 in the vertical direction, and the second bolt 216 is penetrated in the adjustment slot 215, and the second bolt 216 is threadedly connected to the support frame 211, so that the adjustment seat 214 can move in the vertical direction, so that the position of the third driving member 213 can be adjusted conveniently, and the position of the clamping assembly 220 can be adjusted conveniently, so as to improve the use flexibility of the dynamic balancing test device.

[0042] Specifically, refer to Figure 1 and Figure 3 The moving assembly 210 further includes a guide rail 217 and a slider 218.

[0043] It should be noted that two groups of guide rails 217 and sliders 218 are provided to stabilize the position of the support frame 211 so that the support frame 211 can move stably.

[0044] Specifically, refer to Figure 3 , both ends of the guide rail 217 are provided with limit blocks 219, and the slider 218 can abut against the limit blocks 219. By providing the limit blocks 219 at both ends of the guide rail 217, the slider 218 can abut against the limit blocks 219, thereby preventing the slider 218 from sliding out of the guide rail 217, so that the support frame 211 can be stabilized on the guide rail 217, and the movement stability of the support frame 211 is improved.
