Against altitude location clamp 110 to determine the height of top steering arm, side plate 201 is compressed into the positioning that reclines using barb pin 902
Seat 901 adjusts the spacing for belonging to a pair of adjustment seat 800 by screw mechanism, makes interorbital on U-shaped side plate away from conforming to
It asks, track 203 is compressed into the positioning seat 901 that reclines using pressing plate 903.
Work step three：Assemble the tangential guide rail 204 on two blocks of side plates 201.
Work step four：Main driving is hung in into tooling, by being pre-positioned 700 Primary Location of block, keeps ladder sprocket wheel 103 right
Quasi- positioning component 600, the handwheel 501 of rotation apical axis component 500, adjusts the axial position of main driving.
Work step five：The spacing for adjusting two Mobile bases 801, makes two Mobile bases 801 respectively close to corresponding main drive
Dynamic ladder sprocket wheel 103, locks the position of Mobile base 801.
Work step six：The opening width that U-shaped side plate 201 is fixed using opening tie-beam 205, two are fixed using tie-beam
Block side plate 201.
Work step seven：Main driving and top steering arm are linked together with cushion block and bolt.
Work step eight：The attribute block in normal centering component is stirred, the normal point position of tangential guide rail is examined.
Work step nine：Unclamp positioning clamp assembly 900 and altitude location clamp 110, adjustment seat 800 and Mobile base
801 restore to initial position.
Work step ten：Main driving and top steering arm are hung into tooling with suspender, start new working cycles.
Only most preferred embodiment is described in detail above, but should not be understood as its other party implemented to the utility model
The limitation of formula, it is every on the basis of the utility model further improve and similar or identical scheme, be accordingly to be regarded as being this practicality
Novel claimed range.
