[0037] In order to facilitate the adjustment of the inclination angle of the positioning assembly 16, in this embodiment, a first hinge seat 19 is fixedly installed at the middle of one end of the top of the horizontal plate 13 close to the column 2, and a telescopic cylinder 20 is hingedly installed at the top of the first hinge seat 19.

The inclination angle of the assembly plate 21 can be adjusted by the telescopic cylinder 20, and then the inclination angle of the entire positioning assembly 16 can be adjusted.

[0038] In order to enable the positioning assembly 16 to position the rotor, in this embodiment, a top plate 24 is fixedly installed on the top of the side of the assembly plate 21 away from the column 2, a bottom plate 25 is fixedly installed on the bottom of the side of the assembly plate 21 away from the column 2, a first hydraulic cylinder 26 is fixedly installed at the top center of the top plate 24, the output shaft of the first hydraulic cylinder 26 penetrates the top plate 24 and is fixedly installed with a pressure plate 27, guide rods 28 are fixedly installed near the four corners of the top plate 24, guide sleeves 29 are penetrated and installed at the four corners of the pressure plate 27, the guide rods 28 penetrate the guide sleeves 29, and fixed sleeves 30 are fixedly installed near the four corners of the bottom plate 25, and the bottom end of the guide rod 28 is fixedly installed in the fixed sleeve 30. The distance between the pressure plate 27 and the bottom plate 25 can be controlled by the first hydraulic cylinder 26, and the rotor is placed between the bottom plate 25 and the pressure plate 27, so that the pressure plate 27 can be used to press the rotor, thereby achieving positioning.

[0039] In order to ensure that the rotor can remain stable on the bottom plate 25 after the bottom plate 25 is tilted, in this embodiment, a lifting rod 31 is fixedly installed symmetrically along the center of the bottom of the bottom plate 25, a lifting plate 32 is fixedly installed at the bottom end of the lifting rod 31, a second hydraulic cylinder 33 is fixedly installed at the bottom of the lifting plate 32, the output shaft end of the second hydraulic cylinder 33 passes through the lifting plate 32, and a lifting block 34 is fixedly installed at the output shaft end of the second hydraulic cylinder 33, and a push rod 35 is fixedly installed at both ends of the top of the lifting block 34, and the top end of the push rod 35 passes through the bottom plate 25. The use of the push rod 35 to position the hole on the drill can ensure that the rotor will not slide on the bottom plate 25, and combined with the downward pressure of the pressure plate 27, the full-dimensional positioning of the rotor is achieved.

[0040] In order to prevent the push rod 35 from contacting the pressure plate 27 when it is rising and adjusting, and to avoid mutual damage between the pressure plate 27 and the push rod 35, in the present embodiment, a limit rod 36 is fixedly installed on the bottom of one end of the lifting block 34 facing the assembly plate 21, and two limit blocks 37 arranged opposite to each other are fixedly installed on the limit rod 36. A limit assembly 38 is fixedly installed on the side of the bottom of the base plate 25 close to the assembly plate 21.

[0041] In order to enable the limiting assembly 38 to cooperate with the limiting block 37 to limit the limiting rod 36, in this embodiment, the limiting assembly 38 includes a fixing frame 39, and two symmetrically arranged power assemblies 40 are fixedly installed on one side of the fixing frame 39, and one end of the power assembly 40 extends out of the fixing frame 39 and is installed with a rotating shaft 41, and a strip plate 42 is installed at one end of the rotating shaft 41 away from the power assembly 40, and a limiting protrusion 43 is fixedly installed at one end of the strip plate 42 away from the fixing frame 39.

The strip plate 42 can be swung by the rotating shaft 41, and the distance between the limiting protrusion 43 and the rotating shaft 41 can be adjusted by the strip hole 44 and the fixed knob 45, so that the distance between the limiting protrusions 43 on the two power components 40 can be adjusted, so that the initial distance between the limiting protrusion 43 and the limiting block 37 can be adjusted, and different limiting distances can be set according to different situations.

[0043] In order to make the assembly plate 21 have a limiting function when adjusting the angle, in this embodiment, a fixing plate 46 is fixedly installed at one end of the assembly shaft 18, and a plurality of fixing holes (not shown) arranged around the center of the fixing plate 46 are opened on the outer side of the fixing plate 46, and two limiting blocks 47 are fixedly installed on the outer side of the fixing plate 46, and a limiting component 38 is also fixedly installed on the top of the support frame 14 near the fixed plate 46.

[0044] In order to prevent the second hydraulic cylinder 33 from being affected by external factors when the assembly plate 21 is adjusted, in this embodiment, a shielding plate 48 is fixedly installed on one side of the bottom of the base plate 25 away from the assembly plate 21 .

[0045] Through the above scheme of the utility model, the utility model can fix the assembly frame 3 on the column 2 by installing fastening nails in the assembly hole 7 and the assembly groove 8, and by moving the assembly hole 7 to fix it at different heights on the assembly groove 8, the assembly height of the casting component 4 can be adjusted by the assembly frame 3 and the extension rod 6, which is convenient for subsequent installation at different heights in the workshop to facilitate the operation of the staff. At the same time, the first hydraulic cylinder 26 can be used to control the distance between the pressure plate 27 and the bottom plate 25. The rotor is placed between the bottom plate 25 and the pressure plate 27, and the pressure plate 27 can be used to press the rotor to achieve positioning. Moreover, the inclination angle of the assembly plate 21 can be adjusted, and then the inclination angle of the positioned rotor can be adjusted.
