[0022] Therefore, the present application provides an impeller machining positioning clamp, which can adjust the machining angle of the impeller through the cooperation of the turnover device, thereby meeting the machining requirements of various different angles, quickly turning over after machining one side, without the need for the staff to disassemble and install again, thereby reducing the investment of labor cost, improving the overall operation efficiency, and facilitating the use of the staff.

[0023] Embodiment one: from Figure 1 , 2 and 3, an impeller machining positioning clamp comprises a bottom plate 1, a horizontal plate 6 is arranged above the bottom plate 1, a turnover device 2 is arranged above the horizontal plate 6, the turnover device 2 comprises: a servo motor 21 arranged on one side above the horizontal plate 6; two connecting rods 22 are arranged on the top of the horizontal plate 6 on both sides, and the connecting rod 22 close to the servo motor 21 is fixedly connected with the output end of the servo motor 21; an angle disc 24 is arranged on the side of the horizontal plate 6 away from the servo motor 21; a clamping mechanism 23 is arranged above the horizontal plate 6; wherein the clamping mechanism 23 clamps and fixes the impeller, the servo motor 21 drives the clamping mechanism 23 to rotate and turn over the impeller, and the angle disc 24 displays the angle during machining of the impeller.

[0024] In the implementation process, it is particularly worth pointing out that the angle disc 24 can display the angle during the processing of the impeller, so as to enable the staff to process more accurately. The model of the servo motor 21 is not limited, and it can meet the use demand. The servo motor 21 can drive the connecting rod 22 to rotate, thereby driving the impeller to overturn. The impeller can be polished and polished, and the specific processing content can be selected according to the actual operation demand, so as to meet the technical features of the case;

[0025] Further, the clamping mechanism 23 comprises: two installation plates 231 fixedly connected to one side of the connecting rod 22; two threaded rods 233 rotatably connected to the inner walls of the two installation plates 231 through bearings; two first clamping plates 232 fixedly connected to the lower side of the two installation plates 231; two second clamping plates 234 threadedly connected to the upper side of the outer walls of the two threaded rods 233 and slidably connected to the inner walls of the two installation plates 231; wherein, the position height of the second clamping plate 234 is changed by twisting the threaded rod 233, and the impeller is clamped and fixed by the cooperation of the first clamping plate 232 and the second clamping plate 234;

[0026] In the implementation process, it is particularly worth pointing out that the position height of the second clamping plate 234 can be changed by twisting the threaded rod 233, and the impeller can be clamped and fixed by the cooperation between the first clamping plate 232 and the second clamping plate 234. The top of the second clamping plate 234 is provided with a baffle, so as to close the sliding slot of the installation plate 231, thereby avoiding the entry of foreign matters into the inner wall cavity of the installation plate 231;

[0027] Further, the outer walls of the first clamping plate 232 and the second clamping plate 234 are fixedly connected with friction pads 7;

Synchronizers should be provided between the four electric push rods 31, and the staff can control the four electric push rods 31 to work synchronously by using the synchronizers, so that the two second vertical plates 33 can better move along the inner wall of the first vertical plate 32, thereby realizing normal lifting work of the impeller;

[0032] Specifically, on the basis of the above embodiment one, when it is necessary to turn over, the staff starts the electric push rod 31, and the electric push rod 31 can drive the second vertical plate 33 to move along the inner wall of the first vertical plate 32, so that the height of the impeller can be changed, and then the turnover work can be performed.

[0033] Embodiment three: known from Figure 1 , 2As shown in FIGS. 1, 2, 3 and 4, the bottom of the horizontal plate 6 is provided with a rotating device 4, which comprises: an electric rotating disc 41 fixedly connected to the bottom of the horizontal plate 6 and the bottom of the bottom plate 1; an annular slide rail 42 fixedly connected to the top of the bottom plate 1; and a plurality of slide rods 43, each of which is slidingly connected to the inner wall of the annular slide rail 42 and fixedly connected to the bottom of the horizontal plate 6.

The electric rotating disc 41 is not improved in principle and structure, and its specific model is not limited as long as it meets the use requirements. The specific operation mode and installation mode are both known technologies, and therefore will not be described in detail here. Those skilled in the art should understand it in a broad sense.

[0035] Specifically, on the basis of the above-mentioned embodiment one, when positioning the impeller, the staff member starts the electric rotating disc 41, which drives the horizontal plate 6 to rotate and the slide rods 43 to move along the inner wall of the annular slide rail 42 to support the horizontal plate 6.

The filter screen 53 filters the treatment liquid stored in the collecting box 51.

[0037] In the specific implementation process, it is worth noting that the mesh number of the filter screen 53 is not limited as long as it meets the use requirements. The filter screen 53 can filter the treatment liquid, thereby saving the recycling and rapid collection of the treatment liquid. It should be noted that the specification of the collecting box 51 is greater than that of the impeller, thereby ensuring that the treatment liquid on the surface of the impeller can smoothly flow into the inside of the collecting box 51. After the work is completed, the filter screen 53 needs to be disassembled and cleaned, thereby avoiding the clogging of the filter screen 53.

[0038] Specifically, on the basis of the above-mentioned embodiment one, when reprocessing, the treatment liquid can flow into the inside of the collecting box 51 and then be filtered and impurities removed by the filter screen 53, so as to recycle and rapidly collect the treatment liquid.
