Description
Technical field
The utility model relates to positioning device for mechanical machining technical field, specifically refers to a kind of positioning lock mandrel.
Background technology
At present, that relatively commonly uses in machining orientates bearing pin as, and locking adopts bolt, first with pin-and-hole location during operation, is then tightened by bolts.But workpiece will be processed counter sink or use pressing plate during operation, during processing counter sink, machinery requirement suspends, and bolt needs the number of turns of twisting more, consuming time longer; And use during pressing plate and easily hit cutter at processing plane.
Utility model content
The purpose of this utility model is to provide a kind of positioning lock mandrel, has easy to use, that production efficiency is high, quality risk is low and with low cost feature.
The utility model can be achieved through the following technical solutions:
The utility model discloses a kind of positioning lock mandrel, comprise circular expansion sleeve and angle screw, one end bosses of described angle screw is provided with screens step, described screens step diameter is to being provided with the first inclined-plane from inside to outside increased gradually, described expansion sleeve inside is provided with the embedding taper hole coordinated with screens step, described screens step is movable nested enters described embedding taper hole inside, the inwall of described embedding taper hole is provided with second inclined-plane corresponding with the first inclined-plane, the cylindrical of described expansion sleeve is provided with annular projection step, described raised step is arranged on the radially inner side of described expansion sleeve end, the diametric plane of described raised step is provided with some connecting screw holes.By connecting screw hole, can conveniently expansion sleeve be fixed on the working plate of needs installation.Can movable nested expansion sleeve and angle screw mutually by arranging, the rotation of angle screw can make the second inclined-plane of the first slope driving expansion sleeve make radially to produce elastic deformation locking workpiece.After installing workpiece, only need twist two circle angle screw and locating shaft generation elastomeric radial just can be made to lock workpiece, if production lot is comparatively large, directly can be connected with cylinder, reaches the object of Rapid positioning locking.
As further improvement of the utility model, the end of described expansion sleeve is radially provided with the expansion clearance of some deciles.By arranging some expansion clearances, expansion sleeve can be rapidly to outer expansion under external force and produce elastomeric deformable power
As further improvement of the utility model, the axiality of described annular projection step and described expansion sleeve is 0.01, is arranged by the axiality of precision, effectively ensure that the accurate location to workpiece.
A kind of positioning lock mandrel of the utility model, has following beneficial effect:
The first, easy to use, only need twist two circle angle screw and locating shaft generation elastomeric radial just can be made to lock workpiece.
The second, production efficiency is high, if production lot is comparatively large, directly can be connected with cylinder, reaches the object of Rapid positioning locking.
Three, quality risk is low, without the need to using processing counter sink or using pressing plate can complete the fixing of workpiece, avoids the damage that processing counter sink or pressing plate cause workpiece.
Four, with low cost, positioning and locking axle construction simply effectively saves manufacturing cost, and can recycle reduction use cost.
