Abstract
The invention discloses a ring workpiece centering and clamping fixture. A pulling column is perpendicularly mounted and fixed in the center of a base; an eccentric cam is mounted in an opening groove of the pulling column through a pin shaft; a handle is mounted and fixed on the eccentric cam; a pressing plate is mounted on the pulling column at the lower part of the eccentric cam; a plurality of guide rails are arranged on the base in the radius direction; a supported sliding block is arranged on each guide rail; and the two ends of a connecting rod are hinged with each supported sliding block and the edge of the pressing plate. The ring workpiece centering and clamping fixture has the advantages of simple structure, larger clamping force and higher clamping and releasing speed, and has the advantage of clamping a larger workpiece.
Description
Technical field
The present invention relates to a kind of clamping tool for machine work, be specifically related to a kind of circular ring work piece centering clamping device.
Background technology
In field of machining, usually need the excircle of workpiece of annulus class is carried out machining, for the purpose that realizes processing, usually need workpiece centering is clamped on the workbench, although it is more various to be used for the anchor clamps kind of centering clamping in the prior art, but general the existence is not suitable for clamping larger diameter annulus and clamping and loosens the lower defective of efficient.
Summary of the invention
The object of the invention is to: being not suitable for feeling relieved for existing anchor clamps clamps large-scale annulus and clamping and loosens the lower defective of efficient, the invention provides a kind of novel annular workpieces centering clamping device, overcome the existing defects of existing circular ring work piece centering clamping device.
The present invention realizes that the technical scheme that above-mentioned purpose adopts is: described a kind of circular ring work piece centering clamping device, comprise: base, stay column, the stretching slide block, connecting rod, eccentric cam, bearing pin, handle, pressing plate, the central vertical of base install and fix a stay column, described stay column upper end edge central plane position is shaped with open slot, on the stay column of open slot both sides, be shaped with pin shaft hole, in open slot, by bearing pin eccentric cam is installed, be mounted with handle above the described eccentric cam, a pressing plate is installed on the stay column of eccentric cam bottom, on base, be shaped with several guide rails along radial direction, the angle that links to each other between the guide rail equates, at each guide rail a stretching slide block is set, one end of each slide block and a connecting rod is hinged actively, an other end of each connecting rod and the edge port of pressing plate are hinged actively, and the angle between each adjacent connecting rod equates.
Beneficial effect: the present invention is because after adopting said method, the present invention not only has advantage simple in structure, simultaneously, because the employing eccentric cam comes the clamping to workpiece, not only has advantage simple in structure, also have simultaneously clamping force large, clamp and the advantage of loosening speed, in addition, the present invention also has the advantage of the larger workpiece of clamping.
