Description

A kind of center and the dual-purpose boring of eccentric orfice are stretched positioning tool
Technical field
The utility model belongs to Workpiece boring technical field, specifically, relates to a kind of center and the dual-purpose boring of eccentric orfice and to stretch positioning tool.
Background technology
General many workpiece need machining center hole and eccentric orfice, and by scroll chuck, processing work is fixed on the positioning in existing processing tool, then eccentric orfice is processed after centre bore is machined, by regulating scroll chuck, be eccentric orfice clamping again separately, centering once, scroll chuck regulates cumbersome, and for circle or the processing of multi-turn eccentric orfice, carry out clamping separately again, centering, to more bother, be unfavorable for the batch production of workpiece, greatly reduce the efficiency of production, the particularly processing of multi-turn eccentric orfice, the difficulty of processing will increase greatly.
Utility model content
For solving above technical problem, the purpose of this utility model is to provide a kind of center and the dual-purpose boring of eccentric orfice to stretch positioning tool, and can process the eccentric orfice of a circle or multi-turn, can also process the eccentric orfice of different spacing, structure is simple, and easy to process, efficiency is high.
The utility model object is achieved in that a kind of center and the dual-purpose boring of eccentric orfice are stretched positioning tool, its key is: comprise base, described base is provided with at least 3 radial claw chutes, this claw chute is around the axis Central Symmetry distribution of described base, described claw chute is provided with fan-shaped claw, described fan-shaped claw top is provided with locating dowel, and this locating dowel and described base eccentric setting, described locating dowel top is provided with Working piece positioning device.
Adopt said structure, fan-shaped claw can do radial moving around on base, and be fixed on fan-shaped claw locating dowel can with fan-shaped claw synchronizing moving, thus the distance of eccentric adjustment hole skew, multi-turn eccentric orfice is processed, and the eccentric orfice processed is positioned by Working piece positioning device, to process next eccentric orfice.
Above-mentioned positioner comprise be rotated with rationed marketing, rotate backstay and one circle location graduation, described steady pin is vertically fixed on the center at described locating dowel top, the inner of described rotation backstay is set on described steady pin, the outer end of this rotation backstay is provided with the elasticity positioning bead towards centralized positioning seat side, the middle part of this rotation backstay is provided with clamping screw, and the corresponding described location graduation of described clamping screw is arranged.
Adopt said structure, the centre bore cover processed is set in locating dowel, the eccentric orfice of processing work, and rotate the backstay anglec of rotation by regulating, determine the spacing between eccentric orfice, by the upper shaping eccentric orfice in elasticity locating dowel location, then process next eccentric orfice, fast and easy is effective.
Above-mentioned rotation backstay is divided into canned paragraph and flexible positioning section, described canned paragraph and described flexible positioning section hinged, its hinged place is provided with torsion spring, and described flexible positioning section inner end is close on locating dowel end face by the torsion of torsion spring, and described clamping screw is arranged on canned paragraph.
Adopt said structure, when being set in locating dowel by workpiece, upwards pull positioning section, be convenient to place work piece, flexible positioning section radially can extend shortening, thus after mobile fan-shaped claw, synchronous adjustment can to stretch the length of positioning section, more accurately eccentric orfice is positioned.
Above-mentioned flexible positioning section comprises the fixed bar hinged with canned paragraph and is set in the retracting cylinder on this fixed bar, and described elasticity positioning bead is arranged on the outer end of described retracting cylinder.
Adopt said structure, flexible positioning section, by the relative motion of retracting cylinder with fixed bar, realizes extending and shortening.
The vertical range of above-mentioned locating dowel axis and centralized positioning seat axis is L, and the radius R of described locating dowel is less than L, and the length of described rotation backstay equals L.
Adopt said structure, ensure that drill bit can not be got involved in by region in the position of locating dowel, affect the processing of workpiece, rotation backstay can stretch out locating dowel and positions eccentric orfice simultaneously.
Beneficial effect:
A kind of center of the utility model and the dual-purpose boring of eccentric orfice are stretched positioning tool, and can process the eccentric orfice of a circle or multi-turn, can also process the eccentric orfice of different spacing, structure is simple, and easy to process, efficiency is high.
