Above-mentioned screw drive type external centring clamping device, is characterized in that: described clamp arm one is rotatably installed in described rectangular base by screw one, and described clamp arm two is rotatably installed in described rectangular base by screw two.
Above-mentioned screw drive type external centring clamping device, is characterized in that: cut somebody's hair and weld or be fixedly mounted on described guide rod end by screw thread in described inclined-plane.
The present invention compared with prior art has the following advantages:
(1) design of this screw drive type external centring clamping device is very reasonable, simple and compact for structure, and clamp arm one, clamp arm two and jacking block cooperatively interact the three points centering clamping realizing workpiece to foreign round.
(2) this screw drive type external centring clamping device adopts screw drive, and force increasing ratio is large, has auto-lock function.
(3) operation is very easy for this screw drive type external centring clamping device, and operating personnel only need clockwise or rotate counterclockwise screw rod can realize the clamping of workpiece or unclamp.
(4) in use there is not rigid shock in this screw drive type external centring clamping device, thus its long service life.
(5) production technology of this screw drive type external centring clamping device is simple, and requirement on machining accuracy is not high, and a lot of parts are convenient to produce, buy all very much, and thus its production cost is very low, is convenient to promote the use of.
Below by drawings and Examples, the present invention is described in further detail.
