Tether and be connected on bottom plate 101.
Reference picture 2, when carrying out both ends mill endoporus to main shaft housing 4 using the present embodiment main shaft housing fixture, first will
Main shaft housing 4 is secured by bolts in roll-shell 3, then support frame 5 is arranged on to the end of roll-shell 3, then will be turned
Dynamic housing 3 is placed on lower carriage 210, then is arranged on support 220 is compressed on the support column 212 of lower carriage 210, makes compression branch
Second pulley 221 on frame 220 compresses roll-shell 3；Then main shaft housing fixture is arranged on grinding machine platform 13, regulation master
The position of axle clamp tool makes the axis of roll-shell 3 pass through rotation after i.e. the axis of main shaft housing 4 overlaps with the axis of grinding machine rotary head 11
Turn regulating bolt 103 base 1 is fixed on grinding machine platform 13；Heart carrier for bolt is installed on the central term 14 of grinding machine rotary head 11 afterwards
Tool 8, heart-shaped fixture 8 is clamped central term 14, and the other end of heart-shaped fixture 8 is fixedly connected on support frame 5, then will branch
On the prefabricated installation position of the spring for being connected to grinding machine rotary head 11 of two back-moving springs 7 on support 5；Last can opens mill
Bed, grinding machine rotary head 11 is set to drive roll-shell 3 and main shaft housing 4 to be turned in support 2 by heart-shaped fixture 8 and support frame 5
It is dynamic, then one end endoporus of main shaft housing 4 is ground by the inner bore grinding head 12 of grinding machine.By the one end of main shaft housing 4
, it is necessary to dismantle support frame 5 and compress support 220 after endoporus processes, roll-shell 3 is exchanged, then branch is installed again
Support 5 and compression support 220 make the inner bore grinding head 12 of grinding machine be ground the endoporus of the progress other end of main shaft housing 4, so
The axis of main shaft housing 4 is to maintain what is overlapped all the time with the axis of grinding machine rotary head 11, also just ensure that main shaft shell to the full extent
The axiality of the endoporus at the both ends of body 4, so as to substantially increase the axiality for the bearing being arranged in the both ends endoporus of main shaft housing 4.
Because the tip of the central term 14 of grinding machine rotary head 11 is located on the rotation axis of rotary head, and the center position of jacking block 6
It is on the central axis of roll-shell 3 in the central axis of support frame 5, therefore judges that the axis of main shaft fixture is for the ease of observation
It is no to be overlapped with the axis of grinding machine, can also be in the centrally disposed mark of jacking block 6, as long as the tip of central term 14 and top when mounted
The centre mark contact of block 6 can judge whether the axis of main shaft fixture overlaps with the axis of grinding machine, i.e. the position of main shaft fixture
It is adjusted good to put, and can dramatically facilitate the progress of the installment work of operating personnel.
In addition, the central axis of support frame 5 needs to overlap with the axis of roll-shell 3 in the present embodiment, so that grinding machine
Rotary head 11 sustainedly and stably can drive roll-shell 3 to be rotated by heart-shaped fixture 8 and support frame 5.
, it is necessary to which explanation, term " close by the orientation of the instruction such as " center ", " horizontal stroke " or position in description of the present utility model
It is to be described based on orientation shown in the drawings or position relationship, to be for only for ease of description the utility model and simplifying, rather than
The device or element of instruction or hint meaning, which must have, deposits specific orientation, with specific azimuth configuration and operation, therefore can not
