Tightening machine is equipped with 5 tightening axles, wherein 2 tightening axles respectively configure the first variable-position cylinder, 2 tightening axles respectively configure the
Two variable-position cylinders, each cylinder are each equipped with cylinder head mandril, cylinder block, displacement slide plate；5th tightening axle configures flexible gas
Cylinder, the cylinder arrangement have track base, guide rail and connecting plate.
There is designed guide groove track on circular base seat board, switches tightening axle in different location.Four axis works
To make under state, the piston rod of the telescopic cylinder of the 5th tightening axle is stretching state, therefore the 5th tightening axle is not involved in work, and its
His four tightening axles are in the position on 100 circumference of reference circle, i.e. four axis applications.When four Spindle Status conjugate five Spindle Status,
The piston rod of telescopic cylinder retracts, and connecting plate drives the 5th tightening axle to lean out under the constraint of linear guide, it is made to reach indexing
Position on 114.3 circumference of circle.At the same time, two the first variable-position cylinders retract, and under its drive, two tightening axles, which reach, divides
Spend the position on 114.3 circumference of circle；Two second change cylinders stretch out, and under its drive, other two tightening axle also reaches indexing
Position on 114.3 circumference of circle；Therefore five tightening axles enter five axis working conditions, this is four axis, five axis processes of change, and
Five axis become four axis processes in contrast.
" retraction " and " stretching " of above-mentioned meaning refers in the outer circle of a circular base seat board 2, is far from its center of circle
" retraction " is " stretching " close to the center of circle.
Tightening machine is suspended on crossbeam I-steel by transverse translation guide rail, is set between transverse translation guide rail and tightening machine
There is pneumatic equalizer, the operation height of tightening machine can be controlled by stretching back and forth by the guide rod of its cylinder, especially by pressing
The control of button handle.
Vehicle bridge is fixed in vehicle bridge assembly line tooling, realizes tightening for its bolt by tightening machine.
The utility model has the advantage that high degree of automation, easy to operate, high-efficient, is suitable for the big rule of assembly line
Mould Production line；The inaccuracy that can solve torque in bolt fastening substantially increases the assembling quality of connector；Reduce work
The labor intensity of people overcomes the damage that pneumatic impact wrench often results in operator's hand and ancon；Low noise is conducive to environmental protection,
Pneumatic impact wrench is avoided to operator ear bring occupational disease；Quick, registration is adjusted, productive temp is met；This sets
(114.3 pairs of cartwheel requirement are tightened for 5 axis, 4 axis of change and reversed 4 axis, 5 axis of change for adapting to 114.3-100 reference circle
Answer 5 axis, 100 corresponding 4 axis).
