Fig. 2 is the left view of the first bracket.
Detailed description of the invention
Refer to Fig. 1 and Fig. 2, of the present invention in order to understand technical scheme of the present invention better, be also described in detail by reference to the accompanying drawings below by specific embodiment:
Refer to Fig. 1, in an embodiment of the present invention, comprise the following steps:
First step, by the first machining benchmark section 12 of described rotor shaft 1 and the second machining benchmark section 13 respectively frame be placed on first bracket 2 that can slide along horizontal linear guideway 52 and on the second bracket 3;
Described first bracket 2 is arranged the first adjustment support claw group 21, described second bracket 3 is arranged the second adjustment support claw group 31, described first regulates support claw group 21 and described second to regulate support claw group 31 to support the first machining benchmark section 12 and the second machining benchmark section 13 of described rotor shaft respectively
Refer to Fig. 2, the first adjustment support on described first bracket 2 is grabbed group 21 and is comprised two adjustment carrying bolts, second of described second bracket 3 regulates support claw group 31 to arrange two equally and regulates carrying bolt, described first regulates two bolts in support claw group 21 and two bolts in the second adjustment support claw group 31, supports the first machining benchmark section 12 and the second machining benchmark section 13 of described rotor shaft 1 respectively.
The object of such design is the height and position being convenient to adjust rotor shaft 1 in subsequent step, makes described rotor shaft 1 maintenance level, and makes the rotating shaft of the rotating shaft of described rotor shaft 1 and described machine chuck 51 contour.
By regulating the bolt in described first adjustment support claw group 21 and described second adjustment support claw group 31, adjust the height and position of described rotor shaft 1, make described rotor shaft 1 maintenance level and make the rotating shaft of the rotating shaft of described rotor shaft 1 and described machine chuck 51 contour.
Second step, machine chuck 5 is bolted and arranges the first flange 41, rotor shaft head end 14 is bolted and arranges the second flange 42, and universal joint 4 connects described first flange 41 and the second flange 42.
Universal joint 4 is the standard components bought.The effect of the first flange 41 is effects of clamping machine chuck 5, second flange 42 is connect rotor shaft 4.The object of such setting is in subsequent step, increases the flexibility of universal joint 4, is convenient to adjust rotor shaft position on the horizontal level, the rotating shaft of described rotor shaft 1 is overlapped with the rotating shaft of described machine chuck 51;
Third step, on support claw group 21 and described second bracket 3 second is regulated to regulate the adjusting bolt that support claw group 31 is arranged by regulating on described first bracket 2 first, make described rotor shaft 1 maintenance level, and regulate the height and position of described rotor shaft, make described rotor shaft 1 maintenance level, and make the rotating shaft of the rotating shaft of described rotor shaft 1 and machine chuck 51 contour;
Adjust rotor shaft 1 position on the horizontal level by the universal joint 4 connecting the first flange 41 and the second flange 42, the rotating shaft of described rotor shaft 1 is overlapped with the rotating shaft of described machine chuck 51;
4th step, described machine chuck 51 starts to rotate, and rotated by universal joint 4 rotor driven rotating shaft 1, be arranged at the saddle 53 of horizontal linear guide rail 52 along described horizontal linear guide rail 52, near rotor shaft 1, drive lathe tool 54 feed arranged with on knife rest 56, the outer circumference surface of described rotor shaft 1 is processed.
Certainly, saddle is arranged on another horizontal linear guide rail parallel with described horizontal linear guide rail 52 and is also fine, and the object of design is like this convenience increasing rotor shaft processing.
In this method, machine chuck does not play clamping action, and only plays rotor driven rotating shaft 1 rotation.In rotor shaft 1 process, the first bracket 2 and the second bracket 3 support rotor rotating shaft 1 can slided along horizontal linear guide rail 6, therefore rotor shaft 1 can be processed in a free state, effectively overcome the distortion of the rotor shaft 1 caused because of the internal stress in process, and the vibration of the rotor caused by being out of shape.Meanwhile, the tail end face 15 of rotor shaft 1 is separated with lathe top 55, and this makes rotor shaft 1 add man-hour stress to discharge further.Above technological means all ensure that the precision contributing to improving rotor shaft processing, ensures form and position tolerance circularity, the cylindricity of rotor shaft 1, to beat and axiality controls in allowed limits, thus contribute to the rotating speed improving rotor.
In addition, the first described bracket 2 and the second bracket 3 are made up of babbit, this is circularity, axiality owing to establishing rotor shaft 1 on slip babbit support, beats, and contributes to eliminating machine tool accuracy to the impact of rotor shaft 1 machining accuracy, and the precision of processing is higher.
In order to the beating during the course of detection rotor rotating shaft 1, described rotor shaft 1 is arranged end face run-out detection table 7 and circle glitch detection table 8, detect beating of described rotor shaft 1.
Those of ordinary skill in the art will be appreciated that, above embodiment is only used to the present invention is described, and be not used as limitation of the invention, as long as in spirit of the present invention, all will drop in Claims scope of the present invention the change of the above embodiment, modification.
