Labor intensity, improve work efficiency；The clamping of this clamp system, unclamp by right alignment pin, pivoted housing and caster assembly therefor
Realize, pivoted housing is offered correspondence slotted eye, the slotted eye that the caster assembly therefor one end being connected in right alignment pin passes on pivoted housing,
When external driver device drives pivoted housing to rotate, caster assembly therefor can move in spiral type hole slot, thus drive right alignment pin
Moving axially, it is achieved to the clamping of workpiece or unclamp, be driven by then passing through driving means, right alignment pin is capable of
Quickly mobile, it is achieved the Quick-clamped of workpiece, to unclamp, improve the clamping of clamp system and the efficiency unclamped and effect, reduce
Artificial labor intensity, improves work efficiency.In the left side of clamp system, threaded on the little axle of the end of left alignment pin
Having clamping sleeve, make the rotation of left alignment pin make when applied external force acts in left alignment pin, the left alignment pin of rotation will
Clamping sleeve is driven to move axially and be pressed on workpiece, thereby through all carrying out displacement compression from the left and right sides or unclamping work
Part, the clamping that can effectively shorten this clamp system, the time unclamped, the clamping improving this clamp system, the efficiency unclamped and
Effect, improves work efficiency.Additionally, arrange annular groove on the external cylindrical surface of left alignment pin, set in this annular groove
Put limit shaft, and the two ends of this limit shaft pass left axle sleeve, can effectively prevent left alignment pin from turning thereby through this limit shaft
Moving axially time dynamic, improves the efficiency clamping or unclamping and the effect of this clamp system.
