Through the technical scheme, when processing other faces of the crankshaft, the crankshaft needs to be turned, the crankshaft needs to be taken down and turned, and then the crankshaft is clamped again, therefore, before processing, the crankshaft extends into the clamping ring in the clamp firstly, then the electric telescopic rod is started, the clamping ring clamps the crankshaft, and clamping is finished.

Preferably, chuck fixed mounting is in V type fork side, and chuck inner wall equidistance fixed mounting has the arc slope, and the distance between a set of arc slope slightly is greater than the diameter of card roller.

Through above-mentioned technical scheme, there is the gap between a set of arc slope, in order to make card roller move certain angle back card income gap at the roller, the gap height is greater than the radius of card roller simultaneously for even the bent axle lasts the atress when adding man-hour, the card roller also can't be followed its inside and rolled out, has reached spacing tight purpose.

Preferably, rolling disc fixed mounting is in the chuck side, and the rolling disc installs the bearing with the chuck junction, equidistance fixed mounting has electric telescopic handle on the both sides wall of rolling disc symmetry, and electric telescopic handle stretches out end fixed mounting and has the tight circle of clamp, fixed mounting has the slipmat of rubber material on the tight circle of clamp and the bent axle contact surface.

Through above-mentioned technical scheme, the bearing that the junction of rolling disc and chuck set up can effectively be so that when the rolling disc rotates, not take place the friction with the chuck to it is more convenient to make to rotate, presss from both sides tightly the bent axle through electric telescopic handle and tight circle of clamp when compressing tightly simultaneously, thereby it is more convenient to make the bent axle need not artificial participation and let press from both sides tightly when pressing from both sides tightly.

Preferably, a spring group is fixedly mounted at the top end of one side of the rotating disc and the electric telescopic rod, a pressing plate is fixedly mounted at the top end of the spring group, and a clamping roller is sleeved at the extending end of the pressing plate.

Through above-mentioned technical scheme, the card roller cup joints in the clamp plate outer end for pull down the card roller faster when dismantling, push down the clamp plate when carrying out the unblock and make the spring assembly shrink, thereby let the card roller pull out from the gap, thereby whole device accomplishes the unblock and can take place rotatoryly.

Preferably, the spring assembly comprises a spring and a limiting column, the spring is sleeved at the outer end of the limiting column, and a pressing plate is fixedly mounted at the top end of the limiting column.

Through above-mentioned technical scheme, because at the rotation in-process, if only the existence of spring then make when the card roller rolls to arc slope, for receiving the direction of force incomplete along the spring to can lead to the spring to take place crooked, influence follow-up use, come to make the direction of force through spacing post and restraint and make no matter when pushing down the clamp plate, still can both keep the uniformity of power when the card roller is gone into, do not take place to deflect.

Compared with the prior art, the utility model provides an anchor clamps are used in general machine bent axle production possesses following beneficial effect:

1. this anchor clamps are used in general machine bent axle production, through adding man-hour to other faces of bent axle, then need overturn the bent axle, need take off the bent axle after the upset, it is tight again, for this before processing, stretch into the inside of the clamping ring in the anchor clamps with the bent axle earlier, then start electric telescopic handle, let the clamping ring press from both sides tight bent axle, thereby accomplish and press from both sides tightly, when processing is accomplished and needs the upset, press two upper and lower clamp plates, make the spring assembly shrink, let the card roller pull out from the gap of the arc slope of chuck inner wall, spring assembly recovers simultaneously, rotate the rolling disc afterwards, the card roller rolls along with the chuck inner wall simultaneously, along with the rising of slope when meetting the arc slope, the spring assembly shrinks gradually, card roller card is gone into in the gap when rotating the gap department of arc slope, the spring assembly diastole, because the arc slope height is greater than card roller radius, so the card roller can's can't roll out from the gap when not pressing the clamp plate, thereby accomplished the rotation operation, and press from both sides tightly spacing to it.

2. This anchor clamps are used in general machine bent axle production, can effectively make when the rolling disc rotates through the bearing that sets up at the junction of rolling disc and chuck, do not take place the friction with the chuck, thereby it is more convenient to make to rotate, press from both sides tightly the bent axle through electric telescopic handle and clamp ring simultaneously when compressing tightly, thereby it is more convenient to make the bent axle need not artificial participation when pressing from both sides tightly and let press from both sides tightly, because at the rotation in-process, if only the existence of spring then make when the card roller rolls to arc slope, for receiving the force direction and not fully along the spring, thereby can lead to the spring to take place the bending, influence follow-up use, come to make the restraint to the direction of force through spacing post and make no matter when holding down plate, still can both the uniformity of holding power when the card roller card is gone into, do not take place the deflection.
