Abstract
The invention discloses an automatic centering mandrel. The automatic centering mandrel is characterized in that a circular substrate is fixedly installed at each end of a straight through shaft through a fixing key, the circular substrates at the two ends of the straight through shaft are symmetrical, a plurality of guide rails are arranged on the outer side face of each circular substrate in the radius director, included angles between every two adjacent guide rails are equal, a sliding block is arranged on each guide rail, an adjustable clamping jaw is fixedly installed on each sliding block through a bolt, and taper covers, compression sleeves and lock nuts are installed on the straight through shaft at the two ends of the circular substrates. The automatic centering mandrel has the advantages of being simple in structure, reliable in working, and especially suitable for machining outer circles of barrel-shaped workpieces with large diameters.
Description
Technical field
The present invention relates to a kind of mechanical processing technique equipment, be specifically related to a kind of self-centering mandrel, relate in particular to a kind ofly for processing the self-centering mandrel of larger diameter cylindrical workpiece cylindrical, belong to mechanical processing technique equipment technology field.
Background technology
As everyone knows, when processing excircle of workpiece cylindraceous, generally need to use centering mandrel, at present, although self-centering mandrel is not quite similar in structure and above principle, but, this class self-centering mandrel is generally suitable for the workpiece cylindraceous that diameter is less, inapplicable for larger-diameter cylindrical workpiece, so, when processing larger diameter workpiece cylindraceous, generally that an axis is directly fixed with the two ends of workpiece, not only have the defect that efficiency is lower, meanwhile, its versatility is also poor.
Summary of the invention
The object of the invention is to: for existing large cylinder shape workpiece existing above-mentioned defect in process, the invention provides a kind of a kind of self-centering mandrel novel, that be suitable for the use of large cylinder shape workpiece machining.
A kind of self-centering mandrel of the present invention comprises: straight-through axle, locking nut, clamp sleeve, adjustable jaw, guide rail, retainingf key, circular substrate, taper sheath, slide block, it is characterized in that: at the two ends of straight-through axle, each is installed symmetrically and fix a circular substrate with a retainingf key, lateral surface at each circular substrate arranges along radial direction the guide rail that several mutual angles are equal, a slide block is set on each guide rail, the free degree between described slide block and guide rail with mutual slip, on each slide block, with bolt, install and fix an adjustable jaw, on the straight-through axle at circular substrate two ends, be separately installed with taper sheath, clamp sleeve, locking nut.
The course of work of the present invention is: in advance adjustable jaw is fixed on to the suitable position of slide block, by the whole outside that is socketed in adjustable jaw of the inner circle of workpiece, tighten respectively the locking nut at straight-through axle two ends, described locking nut pushes clamp sleeve, taper sheath successively, the tapered slope of taper sheath is synchronously extrapolated by guide rail, and pass through adjustable jaw by Workpiece clamping, and now, the straight-through center line of axle and the dead in line of cylinder type workpiece.
Beneficial effect: can be found out that by structure of the present invention and operation principle simple in structure, reliable operation that the present invention has advantages of is especially suitable for processing larger diameter cylindrical workpiece cylindrical.
