[0019] The shaft assembly center clamp is usually used for manufacturing and repairing the shafts in mechanical equipment. Its function is to fix the position of the shaft and ensure its correct alignment during the assembly or repair process. The shaft assembly center clamp provided by the present invention can clamp both ends of the shaft by setting two sets of clamps 15, so that the shaft can be clamped more firmly, and it can adjust its position according to the length of the shaft to adapt to different shafts.

[0020] Such as Figures 1 - 4As shown in the figure, the utility model provides a technical solution: a conveniently used shaft assembly centering fixture, including a workbench 1. A first fixing frame 2 is fixed at the top end of the workbench 1. A sliding opening 7 is opened at the top end of the workbench 1. A connecting block is slidably connected in the sliding opening 7. A second fixing frame 3 is fixed at the top end of the connecting block. A moving mechanism 6 is arranged at the bottom end of the workbench 1. The moving mechanism 6 includes a mounting frame 601 fixed at the bottom end of the workbench 1. A first lead screw 602 is rotatably connected between the inner walls on both sides of the mounting frame 601. A first motor 604 is fixed on one side of the mounting frame 601. The output end of the first motor 604 penetrates through the mounting frame 601 and is fixed to the first lead screw 602. A moving block 603 is screwed on the outer wall of the first lead screw 602. The connecting block and the moving block 603 are fixed together. A connecting rod is fixed between the inner walls on both sides of the mounting frame 601. The connecting rod penetrates through the moving block 603. First connecting frames 8 and second connecting frames 9 are respectively fixed on one side of the first fixing frame 2 and the second fixing frame 3. A second lead screw 10 is rotatably connected between the inner walls at both ends of the first connecting frame 8. A third lead screw 11 is rotatably connected between the inner walls at both ends of the second connecting frame 9. Both the second lead screw 10 and the third lead screw 11 are double-headed lead screws. Sliders 12 are screwed on the outer walls at both ends of the second lead screw 10 and the third lead screw 11. Limit rods are fixed between the inner walls at both ends of the first connecting frame 8 and the second connecting frame 9. The limit rods penetrate through the sliders 12. Clamps 15 are fixed at the ends of the sliders 12 that are close to each other.

[0021] It should be noted that by starting the first motor 604, the first motor 604 drives the first lead screw 602 to rotate. The rotation of the first lead screw 602 drives the moving block 603 to move. The movement of the moving block 603 drives the second fixing frame 3 to move. In this way, the position of the second fixing frame 3 can be adjusted according to the length of the shaft, so as to better clamp the shaft, avoiding the situation that only one end of the shaft is clamped, which may cause the shaft not to be clamped firmly and shake during the clamping process. In addition, by rotating the second lead screw 10 and the third lead screw 11, the sliders 12 move, so that the clamps 15 move to clamp the shaft.

[0022] Such as Figure 1 、 Figure 2 and Figure 3As shown in the figure, a power mechanism 5 is provided at the top of the workbench 1. The power mechanism 5 includes two fixing plates 501 fixed to the top of the workbench 1. A rotating column 502 is rotatably connected between the two fixing plates 501. A limiting strip is fixed to the outer wall of the rotating column 502. A first worm 503 is fixed to the outer wall of the rotating column 502. A second worm 504 is slidably connected to the outer wall of the rotating column 502. The inner wall of the second worm 504 is adapted to the rotating column 502 and the limiting strip. The second worm 504 is a hollow structure, and a limiting groove adapted to the rotating column 502 and the limiting strip is formed inside it. One end of the second fixing frame 3 is fixed with a fixing member 507. Through holes are formed at both ends of the fixing member 507. The rotating column 502 and the limiting strip are located inside the through holes. The second worm 504 is located between the inner walls on both sides of the fixing member 507. The second lead screw 10 and the third lead screw 11 respectively pass through the first fixing frame 2 and the second fixing frame 3, and a first worm gear 505 and a second worm gear 506 are respectively fixed to their outer walls. The first worm gear 505 meshes with the first worm 503, and the second worm 504 meshes with the second worm gear 506. A second motor is fixed to the side of one of the fixing plates 501 away from the rotating column 502. The output end of the second motor passes through the fixing plate 501 and is fixed to the rotating column 502. A fixing rod 13 is fixed to one side of the first fixing frame 2. The fixing rod 13 passes through the second fixing frame 3. A sliding sleeve 14 is fixed to the other side of the second fixing frame 3. The sliding sleeve 14 is slidably connected to the outer wall of the fixing rod 13. Fixing strips 16 are fixed to one side of both the first fixing frame 2 and the second fixing frame 3. A sliding member 17 is fixed to the top of the fixture 15. The sliding member 17 is slidably connected to the outer wall of the fixing strip 16. A controller 4 is installed on the other side of the first fixing frame 2. The controller 4 is electrically connected to the first motor 604 and the second motor.

[0023] It should be noted that by starting the second motor through the controller 4, the second motor drives the rotating column 502 to rotate. The rotation of the rotating column 502 drives the first worm 503 and the second worm 504 to rotate, so that the first worm gear 505 and the second worm gear 506 rotate. The rotation of the second lead screw 10 and the third lead screw 11 drives the slider 12 to move, so that the fixture 15 clamps the rotating shaft.

[0024] Working principle: By starting the first motor 604 through the controller 4, the first motor 604 drives the first lead screw 602 to rotate. The rotation of the first lead screw 602 drives the moving block 603 to move. The movement of the moving block 603 drives the second fixing frame 3 to move. In this way, after adjusting the position of the second fixing frame 3 according to the length of the rotating shaft, the rotating shaft is placed into the first fixing frame 2 and the second fixing frame 3. By starting the second motor through the controller 4, the second motor drives the rotating column 502 to rotate. The rotation of the rotating column 502 drives the first worm 503 and the second worm 504 to rotate, so that the first worm gear 505 and the second worm gear 506 rotate. The rotation of the second lead screw 10 and the third lead screw 11 drives the slider 12 to move, so that the fixture 15 clamps the rotating shaft.

[0025] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended embodiments and their equivalents.
