Abstract

The invention discloses a centring clamping device which comprises a base, a clamping module and a driving module, wherein the base comprises a base body; the base body is provided with a central shaft; the clamping module comprises two first clamping jaw units arranged oppositely and two second clamping jaw units arranged oppositely; each of the first clamping jaw units is provided with a first clamping jaw; each of the second clamping jaw units is provided with a second clamping jaw; the driving unit comprises a first rotary disc, a second rotary disc, two first driving units and two second driving units; the first driving units drive the first rotary disc to drive the first clamping jaws of the first clamping jaw units to move in the direction of the central shaft; and the second driving units drive the second rotary disc to drive the second clamping jaws of the second clamping jaw units to move in the direction of the central shaft, so that a workpiece is clamped and fixed on the central shaft by means of the first clamping jaws and the second clamping jaws.

Description

technical field [0001] The invention relates to a workpiece clamping device, in particular to a centering clamping device. Background technique [0002] like figure 1 , 2 As shown, an existing centering and clamping device 1 includes a mandrel 11 , two turntables 12 pivotally mounted on the mandrel 11 , and four cylinders disposed on the mandrel 11 and capable of driving the turntables 12 to rotate. 13. Four movable claws 14 and four guide blocks 15 respectively connected to the movable claws 14. Each turntable 12 has two eccentric arc grooves 121 which are respectively arranged at both ends and are symmetrical to each other. The center of the circle 12 is the symmetrical point of the eccentric arc groove 121, the movable jaws 14 are arranged in a pairwise opposite manner, and one end of the guide block 15 to which the two oppositely arranged movable jaws 14 are connected The eccentric arc grooves 121 of one turntable 12 are respectively slidably connected to each other, ...
