The device that current axiality detected can only detect the spare part of same specification, and the axiality of motor inner shell and the axiality of assembly back pivot and inner shell can only separately detect, can not realize many specifications through the adjustment and detect, has the limitation, and the cost is also higher.
SUMMERY OF THE UTILITY MODEL
The utility model aims at: the coaxiality detection device of the inner shell and the rotating shaft is applicable to the coaxiality of the inner shells of different specifications and the coaxiality of the rotating shaft and the inner shell after assembly, and the cost is reduced.
In order to achieve the above object, the present invention provides the following technical solutions:
the coaxiality detection device of the inner shell and the rotating shaft comprises a bottom plate and a dial indicator, wherein a polygonal column is connected to the bottom plate; the side surface of the polygonal column is respectively detachably connected with a plurality of inner shell detection columns and a plurality of assembly detection columns, and the axes of the inner shell detection columns and the axes of the assembly detection columns are perpendicular to the axis of the polygonal column; one end of the assembly detection column, which is far away from the polygonal column, is provided with a rotating hole; the top rotatable coupling of polygon post has the bull stick, bull stick one end rotatable coupling just passes through set screw to be connected on the polygon post, and bull stick other end linear array is provided with a plurality of through-holes, and the percentage table is placed in the through-hole.
Furthermore, one end of the rotating rod connected with the polygonal column is the same as the polygonal column in shape; the polygonal column is specifically hexagonal.
Further, the diameters of the detection columns of the inner shells are different; the diameters of the assembly detection columns are different; the inner shell detection column and the assembly detection column are detachably connected to the polygonal column through screws.
The utility model has the advantages that: a axiality detection device of inner shell and pivot, adopt rotatable formula bull stick area cooperation percentage table, can be suitable for the axiality of the inner shell of different specifications and the axiality of assembly back pivot and inner shell simultaneously, reduce cost.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
Referring to fig. 1 to 2, the device for detecting the coaxiality of the inner shell and the rotating shaft comprises a bottom plate 1 and a dial indicator 6, wherein a polygonal column 2 is connected to the bottom plate 1; the side surface of the polygonal column 2 is respectively detachably connected with a plurality of inner shell detection columns 3 and a plurality of assembly detection columns 4, and the axes of the inner shell detection columns 3 and the axes of the assembly detection columns 4 are both vertical to the axis of the polygonal column 2; one end of the assembly detection column 4, which is far away from the polygonal column 2, is provided with a rotating hole 41; the top rotatable coupling of polygon post 2 has bull stick 5, 5 one end rotatable coupling of bull stick is on polygon post 2 and through set screw 7 connection on polygon post 2, 5 other end linear array of bull stick is provided with a plurality of through-holes 51, and percentage table 6 places in through-hole 51.
The connecting end of the rotating rod 5 and the polygonal column 2 is the same as the polygonal column 2 in shape; the polygonal column 2 is specifically hexagonal.
The diameters of the plurality of inner shell detection columns 3 are different; the diameters of the plurality of fitting detection columns 4 are different; inner shell detects post 3 and assembly and detects post 4 and all can dismantle the connection on polygon post 2 through the screw.
The working principle is as follows: when the coaxiality of the inner shell of the motor needs to be detected: will need to detect the motor inner shell cover on the inner shell detection post 3 of corresponding size, will change bull stick 5 and go to this inner shell detection post 3 directly over to through set screw 7 locking, insert corresponding through-hole 51 with percentage table 6 in, stir the motor inner shell, observe the percentage table and beat, judge whether the axiality meets the requirements.
When the axiality of pivot and inner shell after the needs detect the assembly, insert the pivot in the commentaries on classics hole 41 of corresponding assembly detection post 4, rotate this assembly detection post 4 directly over with bull stick 5 simultaneously to through set screw 7 locking, insert corresponding through-hole 51 with percentage table 6 in, stir the inner shell and make the whole of pivot and inner shell rotate round the pivot, observe the percentage table and beat, judge whether the axiality of pivot and inner shell meets the requirements.
