Abstract
The invention discloses a V-shaped spring disc centering fixture. The V-shaped spring disc centering fixture comprises a mandrel, a positioning block coating the mandrel, a pair of end surface cushion plates, and two or more V-shaped elastic discs positioned between the end surface cushion plates; the end surface cushion plates and the V-shaped elastic disc are arranged in workpiece center holes; separation sleeves are connected among the V-shaped elastic discs; and the end surface cushion plate on one side is connected with a jacking nut. The V-shaped spring disc centering fixture can quickly and accurately perform centering correction for cylindrical shells through the V-shaped spring discs, is simple in structure, convenient for operation, high in centering precision and reliable in clamping, saves both time and labors in workpiece disassembly, and is low in labor intensity of operators, high in production efficiency and low in production cost.
Description
Technical field
The invention belongs to the clamping of workpiece or cutter, supporting, positioner, the technical field generally can pulled down from lathe, be specifically related to a kind of V-arrangement spring holder centralizer.
Background technology
Process columnar housing the dimensional accuracy of hole machined in shell and position accuracy demand is higher, generally the processing method to shell inner hole is first to adopt three-jaw chuck that housing is carried out clamping, after correction housing end face and endoporus center, housing is carried out turning end cylindrical and arc surface processing again, generally use scroll chuck to accommodate workpiece when turnery processing, but run into high-volume workpiece to need to add man-hour, when adopting scroll chuck to accommodate part existence dismounting part cost, effort, operator's labor intensity is high, production efficiency is low, the correction accuracy of end face and endoporus is poor, time is long, clamping efficiency is low.
Summary of the invention
In view of this, it is an object of the invention to provide a kind of V-arrangement spring holder centralizer, this V-arrangement spring holder centralizer corrects by adopting V-arrangement spring holder can carry out centering fast, accurately to columnar housing, and simple in construction is easy to operate, centering precision is high, reliable clamping, dismounting workpiece is time saving and energy saving, and operator's labor intensity is low, production efficiency is high, and production cost is low.
In order to achieve the above object, one V-arrangement spring holder centralizer of the present invention, including on mandrel, described mandrel be set with locating piece, a pair end face backing plate and between end face backing plate no less than 2 V-arrangement resilient discs, described end face backing plate and V-arrangement resilient disc are arranged in workpiece center hole, being connected to spacer between described V-arrangement resilient disc, described in side, end face backing plate is connected to and holds out against nut.
Further, described mandrel is provided with the ring flange being connected with machine tool chief axis away from the other end holding out against nut.
Further, described mandrel is provided with bolt hole, institute's bolt hole is connected to and fixes the bolt being connected with ring flange.
Further, described mandrel upper bolt hole arranged outside has annular groove, and described locating piece is provided with the projection being contained in annular groove.
Further, also including the position-arresting disk being sleeved on mandrel, described position-arresting disk is between V-arrangement resilient disc and spacer.
The beneficial effects of the present invention is:
V-arrangement spring holder centralizer of the present invention corrects by adopting V-arrangement spring holder can carry out centering fast, accurately to columnar housing, and simple in construction is easy to operate, centering precision is high, reliable clamping, and dismounting workpiece is time saving and energy saving, operator's labor intensity is low, and production efficiency is high, and production cost is low.
Accompanying drawing explanation
Fig. 1 is the structural representation of V-arrangement spring holder centralizer of the present invention.
Accompanying drawing labelling: 1-ring flange；2-mandrel；3-end face backing plate；4-spacer；5-holds out against nut；6-V shape resilient disc；7-position-arresting disk；8-workpiece；9-locating piece；10-center hole.
Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail.
It is illustrated in figure 1 the structural representation of V-arrangement spring holder centralizer of the present invention；One V-arrangement spring holder centralizer of the present invention, including on mandrel 2, described mandrel 2 be set with locating piece 9, a pair end face backing plate 3 and between end face backing plate 3 no less than 2 V-arrangement resilient discs 6, described end face backing plate 3 and V-arrangement resilient disc 6 are arranged in workpiece 8 centre bore, being connected to spacer 4 between described V-arrangement resilient disc 6, end face backing plate 3 described in side is connected to and holds out against nut 5.
The present embodiment corrects by adopting V-arrangement spring holder can carry out centering fast, accurately to columnar housing, and simple in construction is easy to operate, centering precision is high, reliable clamping, and dismounting workpiece is time saving and energy saving, operator's labor intensity is low, and production efficiency is high, and production cost is low.
Further, it is preferred that described mandrel 2 is provided with the ring flange 1 being connected with machine tool chief axis away from the other end holding out against nut 5, this structure is conducive to being arranged on lathe by centralizer, it is simple to dismounting.
Further, on preferred described mandrel, 2 are provided with bolt hole, institute's bolt hole is connected to the bolt that be connected fixing with ring flange 1, described mandrel 2 upper bolt hole arranged outside has annular groove, described locating piece 9 is provided with the projection being contained in annular groove, this structure is easy to stationary positioned block, improves the positioning datum of locating piece 9.
Further, also including the position-arresting disk 6 being sleeved on mandrel 2, described position-arresting disk 7 is between V-arrangement resilient disc 6 and spacer 4.
The present embodiment fixture is connected with machine tool chief axis by ring flange 1, mandrel 2 other end is connected by center hole 10 is top with lathe, V-arrangement resilient disc 6 is arranged on mandrel 2, and separate with spacer 4, V-arrangement resilient disc 6 axially positions with end face backing plate 3, workpiece 8 is sleeved on V-arrangement resilient disc, one end abuts against on locating piece 9, rotation holds out against nut 5, by spacer 4, axial force is added on V-arrangement resilient disc 6 so that it is radially enlarged, thus workpiece 8 being felt relieved and stepping up, position-arresting disk 7 plays axial limiting effect, it is prevented that V-arrangement resilient disc 6 deforms more than elastic limit.
What finally illustrate is, preferred embodiment above is only in order to illustrate technical scheme and unrestricted, although the present invention being described in detail by above preferred embodiment, but skilled artisan would appreciate that, in the form and details it can be made various change, without departing from claims of the present invention limited range.
