Then, the two adjusting assemblies 3 are used to enable the two clamping assemblies 4 to move toward each other, so that the armature shaft 5 can be clamped and fixed. Then, the processing equipment installed on the surface of the processing equipment mounting frame 2 can be used for processing.

[0028] like Figure 2 As shown, the adjustment assembly 3 includes two hydraulic rods 31. The two hydraulic rods 31 are fixedly connected to the inner wall of the base plate 1 near the right side of the armature shaft 5. The output ends of the two hydraulic rods 31 are fixedly connected to a U-shaped plate 32. The inner wall of the U-shaped plate 32 is movably connected to the inner wall of the base plate 1. The upper surfaces of the front and rear parts of the U-shaped plate 32 are fixedly connected to a fixing bracket 33, and the fixing bracket 33 is located on the upper surface of the base plate 1.

[0029] Through the action of the hydraulic rod 31, the U-shaped plate 32 can push the fixing frame 33 and the mounting seat 34 to move, so that the two fixing seats 41 can move toward each other. Under the action of the two fixing seats 41, the outer walls of the opposing parts of the two conical bodies 42 can be engaged with the inner walls of the left and right parts of the armature shaft 5, thereby clamping and fixing the armature shaft 5.

[0030] like Figure 3 As shown, the inner wall of the fixing frame 33 is fixedly connected to the mounting seat 34, and the inner cavities of the upper, lower, front and rear parts of the mounting seat 34 are all threadedly connected with screws 35. The outer wall of the four screws 35 away from the mounting seat 34 is threadedly connected to the inner cavities of the upper, lower, front and rear parts of the fixing seat 41 respectively.

[0031] Through the functions of the mounting base 34 and the screws 35 , the fixing base 41 can be easily installed, fixed, disassembled, repaired and replaced, thereby being easy to use.

[0032] like Figure 4 As shown, the opposite surfaces of the front and rear parts of the U-shaped plate 32 are fixedly connected to sliders 36, and the two sliders 36 are located below the fixed frame 33.

[0033] Through the action of the slider 36 , the guide rail 37 and the moving wheel 38 , the U-shaped plate 32 can stably and smoothly drive the fixing frame 33 and the mounting seat 34 to move, thereby facilitating the two conical bodies 42 to clamp and fix the armature shaft 5 .

[0034] like Figure 5 As shown, a threaded rod 44 is rotatably connected to the side of the middle portion of the limiting square sleeve 43 away from the conical body 42, a threaded sleeve 45 is threadedly connected to the outer wall of the threaded rod 44, and the outer wall of the threaded sleeve 45 is fixedly connected to the inner wall of the fixing seat 41, and a moving block 46 is fixedly connected to the side of the threaded rod 44 away from the limiting square sleeve 43, and a cross groove is formed on the side of the moving block 46 away from the threaded rod 44;

[0035] By inserting the cross rod into the interior of the moving block 46 and then rotating it, the threaded rod 44 can rotate and move under the action of the threaded sleeve 45, so that the conical body 42 can move toward the armature shaft 5 under the push of the limiting square sleeve 43, so that the two exposed conical surfaces of the conical body 42, one large and one small, can be adjusted according to the size of the armature shaft 5, thereby facilitating use.

[0039] Since the outer wall of the conical body 42 close to the armature shaft 5 is provided with two conical surfaces, one large and one small, the armature shaft 5 can be adjusted according to the size of the armature shaft 5 when being fixed.

[0040] The working principle of the present invention is as follows: first, the cross rod is inserted into the interior of the moving block 46 and then rotated so that the threaded rod 44 can rotate and move under the action of the threaded sleeve 45, so that the conical body 42 can move toward the armature shaft 5 under the push of the limiting square sleeve 43, so that the two conical surfaces, one large and one small, exposed outside the conical body 42 can be adjusted according to the size of the armature shaft 5, and then the U-shaped plate 32 can push the fixing frame 33 and the mounting seat 34 to move through the action of the hydraulic rod 31, so that the two fixing seats 41 can move toward each other.
