[0022] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0023] Example 1:

[0024] Impeller string press, such as Figures 1 to 3 As shown, the device includes a support frame 1, on which a drive component 2, a clamping assembly 3, and a positioning seat 4 are mounted. The output end of the drive component 2 is connected to a pressure block 5. The drive component 2 is used to drive the pressure block 5 to apply pressure to the upper surface of the impeller string unit at the top of the impeller string. In this embodiment, the drive component 2 is preferably a cylinder. The cylinder drives the pressure block 5 to move, so that the pressure block 5 approaches or moves away from the impeller string unit at the top of the impeller string. Alternatively, the drive component 2 can also be a hydraulic cylinder or an electric cylinder.

[0025] A pressing groove 8 is provided on the bottom surface of the pressing block 5. The pressing groove 8 is adapted to the top of the impeller string unit. When the pressing block 5 applies pressure to the upper surface of the impeller string unit at the top of the impeller string, the inner wall of the pressing groove 8 is in contact with the outer surface of the impeller string unit, so that the pressing block 5 can apply pressure to the impeller string unit more stably and achieve better results.

[0026] The positioning seat 4 is used to position the individual impeller units at the bottom of the impeller string. Specifically, the positioning seat 4 is adapted to the bottom groove of the individual impeller units to position the impeller string, prevent the position of the impeller string from shifting, and thus ensure the stability of the impeller string.

[0027] Furthermore, the positioning seat 4 is detachably connected to the support frame 1 via fasteners. Preferably, the fasteners are bolts, which pass through the positioning seat 4 and are threadedly connected to the support frame 1, thereby achieving a stable connection between the positioning seat 4 and the support frame 1 and enabling the positioning seat 4 to be detached. This facilitates the removal, replacement, and maintenance of the positioning seat 4. It should be noted that since the impeller strings have different specifications and sizes, the positioning seat 4 of different specifications and sizes can be replaced to adapt to the impeller strings, thereby increasing the range of applications.

[0028] The clamping assembly 3 is used to clamp the impeller unit at the bottom of the impeller string. Through the clamping action of the clamping assembly 3, the stability of the impeller string is further ensured during the pressing process.

[0029] Preferably, the clamping assembly 3 includes a dual-shaft cylinder 31 and two clamping blocks 32. The two clamping blocks 32 are arranged opposite to each other. The output end of the dual-shaft cylinder 31 is connected to the two clamping blocks 32. The dual-shaft cylinder 31 is used to drive the two clamping blocks 32 to move closer or further apart. When it is necessary to clamp the impeller string individual at the bottom of the impeller string, the dual-shaft cylinder 31 drives the two clamping blocks 32 to move closer to each other, so that the two clamping blocks 32 cooperate to clamp the impeller string individual. After the clamping work is completed, the dual-shaft cylinder 31 drives the two clamping blocks 32 to move further apart, so that the impeller string can be removed.

[0030] Both clamping blocks 32 are provided with V-shaped clamping grooves 6. The V-shaped clamping grooves 6 can be adapted to impeller strings of different sizes, making them more widely applicable.

[0031] The support frame 1 is equipped with a controller 7, which is electrically connected to the drive component 2 and the dual-axis cylinder 31. The controller 7 can control the start and stop of the drive component 2 and the dual-axis cylinder 31, and the status and stroke value of the drive component 2 can be viewed on the controller 7.

[0032] The output end of the pressure block 5 and the drive component 2 are detachably connected. The pressure block 5 and the output end of the drive component 2 can be detachably connected by thread or bolt. The pressure block 5 can be detached for replacement and maintenance. It can be used for impeller strings of different sizes to meet different needs and has a wider range of applications.

[0033] The working principle of this utility model is as follows:

[0034] First, place the impeller string onto the positioning seat 4, then start the dual-shaft cylinder 31. The dual-shaft cylinder 31 drives the two clamping blocks 32 to move closer to each other. The two clamping blocks 32 cooperate to clamp the impeller string individual. Then start the drive component 2. The drive component 2 drives the pressure block 5 to move. The pressure block 5 presses on the upper surface of the impeller string individual at the top of the impeller string to apply pressure. After the clamping work is completed, the dual-shaft cylinder 31 drives the two clamping blocks 32 to move away from each other and remove the impeller string.

[0035] Example 2:

[0036] The difference between Example 2 and Example 1 is that, as Figure 4 As shown, the dual-axis cylinder 31 is mounted on the support body 9. The bottom of the support body 9 is detachably provided with a heightening body 10. The heightening body 10 is detachably mounted on the support frame 1. Dovetail blocks 11 are provided on the surface of the support frame 1 and the upper surface of the heightening body 10. Dovetail grooves 12 adapted to the dovetail blocks 11 are provided on the bottom of the heightening body 10 and the bottom of the support body 9. The dovetail blocks 11 can be inserted into the dovetail grooves 12.

[0037] It should be noted that when disassembling and assembling the heightening body 10, only the dovetail blocks 11 on the surface of the support frame 1 are disengaged from or inserted into the dovetail grooves 12 at the bottom of the heightening body 10 and the dovetail blocks 11 on the upper surface of the heightening body 10 are disengaged from or inserted into the dovetail grooves 12 at the bottom of the support body 9, and the operation is simple and convenient to disassemble and assemble. After the heightening body 10 is disassembled, only the dovetail blocks 11 on the surface of the support frame 1 are inserted into the dovetail grooves 12 at the bottom of the support body 9, and the relative stability of the support frame 1 and the support body 9 can be achieved.

[0038] It should be noted that the height position of the double-shaft air cylinder 31 can be changed by disassembling and assembling the heightening body 10, and the position of the two clamping blocks 32 clamped by cooperation can be changed, so as to be suitable for impeller strings of different heights, and the application range is wider. Of course, according to actual needs, the number of heightening bodies 10 can be appropriately increased or reduced according to actual needs.

[0039] The specific embodiments described herein are merely illustrative of the present application; those skilled in the art of the present application can make various modifications or supplements to the described specific embodiments or replace them with similar ways, but will not deviate from the spirit of the present application or exceed the scope defined by the appended claims.
