Description
Technical field
The utility model belongs to the device that is used to process the cover-plate type part on a kind of drilling machine.
Background technology
The positioning core axle and the workpiece bore clearance of the cover-plate type drill jig swelling device that uses are big at present, Heavy Weight, and complicated operation, and machining accuracy is poor, and production efficiency is low.
Summary of the invention
The utility model provides a kind of cover-plate type drill jig swelling device, has solved the prior art positioning core axle with tight and the workpiece bore clearance is big, Heavy Weight, the problem of complicated operation.The technical scheme that the utility model is taked is: positioning core axle 4 is connected with cover plate 3 by screw 10, swelling pin 6 difference matched in clearance are in the pin-and-hole of this positioning core axle, one end of spring 7 withstands on the baffle plate 5, the other end withstands on the swelling pin, baffle plate 5 is connected with positioning core axle by screw 8, milled screw 1 is threaded with this positioning core axle, hangs in the space of three swelling pin formation to be placed with steel ball 2, and drill bushing 9 is a tight fit on 3.During work, positioning core axle 4 is packed in the workpiece hole, the milled screw 1 that turns clockwise, compressing steel ball 2 moves down, and this steel ball promotes the inclined-plane of three swelling pins 6, and it is outwards moved simultaneously, locatees with the swelling of workpiece hole wall.Milled screw 1 is rotated counterclockwise, and under the effect of spring 7, three swelling pins 6 will be withdrawn.
Advantage of the present utility model is: novel structure, simple to operate, flexibly, volume is little, and is in light weight, and the positioning core axle diameter is replaceable, has brought convenience to the operator, improved work than rate.
Description of drawings
Accompanying drawing is the utility model structural representation.
