Description
Technical field
The invention belongs to Machining Technology field, relate to a kind of aperture middle mold tapering grinding
Device.
Background technology
In abrasive machining device in machining device, grind for aperture middle mold tapering
Turning device, uses scroll chuck to clamp middle mold often, then grinds with high-speed grinder
Mill, by the angular compliance between scroll chuck and high-speed grinder, grinding goes out middle mold
Tapering.Scroll chuck, when clamping middle mold, easily makes the surface damage of middle mold, in impact
The fineness on mould surface；It addition, scroll chuck is when clamping middle mold carries out rotary grinding,
It is susceptible to position cheap, causes machining accuracy to be affected.
In order to overcome the deficiencies in the prior art, people have passed through constantly exploration, it is proposed that
Various solutions, as Chinese patent literature discloses a kind of vertical shaft type taper mill
Turning device [patent No.: CN102476329B], it has transverse feed mechanism, laterally drags
Plate, vertical feeding mechanism, vertical saddle, slew gear, Vertical Mill head, described laterally drag
Its back side of plate is connected with transverse feed mechanism, and frontal design is box shell structure, interior
Portion is provided with slew gear；Described slew gear be arranged on cross slide and vertical saddle it
Between；Slew gear has swivel mounting member, and swivel mounting member is circumscribed with brake hoop, described
It is connected with machine rotary tray above brake hoop, side and hydraulic locking attached components.
Such scheme need not widen emery wheel, can reduce production cost；Vertical shaft shape can be processed
The steep-taper of formula, long tapering part, can improve tapered surface roughness and machining accuracy,
Improve grinding efficiency.But program structure is complicated and cannot be used for processing middle mold tapering.
Summary of the invention
It is an object of the invention to for the problems referred to above, it is provided that a kind of simple in construction, clamping jail
Gu, aperture middle mold taper grinding device that grinding accuracy is high.
For reaching above-mentioned purpose, present invention employs following technical proposal: in a kind of aperture
Mould taper grinding device, including high-speed grinder and fixture, described speed lapping facility
There is bistrique, described fixture is folded with collet expander assembly, described collet expander group
The end of part is inserted in middle mold and expands fixing with middle mold.
In above-mentioned aperture middle mold taper grinding device, described fixture is scroll chuck,
Described collet expander assembly include the collet expander body that is folded in scroll chuck and with
The expansion-head that collet expander body end is affixed, described expansion-head be inserted in middle mold and
Expand fixing with middle mold.
In above-mentioned aperture middle mold taper grinding device, described collet expander body in
Cylindrical.
Compared with prior art, it is an advantage of the current invention that: simple in construction, processing side
Just, the fixation expanding method of clamping is reliable, improves work efficiency and middle mold tapering
The precision of grinding.
Accompanying drawing explanation
Fig. 1 is the structural representation that the present invention provides；
Fig. 2 is the structural representation in another direction that the present invention provides.
In figure: high-speed grinder 10, bistrique 11, fixture 20, scroll chuck 21, swollen
Swollen chuck component 30, collet expander body 31, expansion-head 32, middle mold 100.
Detailed description of the invention
With detailed description of the invention the present invention done further details of theory below in conjunction with the accompanying drawings
Bright.
As depicted in figs. 1 and 2, a kind of aperture middle mold taper grinding device, including at a high speed
Grinder 10 and fixture 20, described high-speed grinder 10 has bistrique 11, described
Collet expander assembly 30, the end of described collet expander assembly 30 it is folded with on fixture 20
Portion is inserted in middle mold 100 and expands fixing with middle mold.
The present invention, grips middle mold 100 by the way of expanding and fixing, Gu
Fixed reliable, working (machining) efficiency is high, and precision is high.
Preferably, fixture 20 is scroll chuck 21, and described collet expander assembly 30 wraps
Include the collet expander body 31 being folded in scroll chuck 21 and with collet expander body 31
The expansion-head 32 that end is affixed, collet expander body 31 in cylinder, described expansion
32 are inserted in middle mold and expand fixing with middle mold.
The work process of the present invention is:
The die cavity of middle mold 100 is inserted in expansion-head 32, the diameter ratio of expansion-head 321
The die cavity little 1-3 silk of middle mold 100, drops into expansion-head 32 with setscrew after insertion
In, make expansion-head 32 coordinate with middle mold swelling, namely middle mold 100 is solid with expansion-head 32
Fixed.When scroll chuck 21 rotates, middle mold 100 is driven to rotate, high-speed grinder 10
Band rotary bistrique 11 high speed rotating.Angulation between scroll chuck 21 and bistrique 11,
Bistrique 11 can form tapering grinding to middle mold 100.
Present configuration is simple, easy to process, and the fixation expanding method of clamping is reliable,
Improve work efficiency and the precision of middle mold 100 tapering grinding.
Specific embodiment described herein is only to present invention spirit theory for example
Bright.Those skilled in the art can be to described specific embodiment
Make various amendment or supplement or use similar mode to substitute, but without departing from
The spirit of the present invention or surmount scope defined in appended claims.
Although the most more employing double acting flat-nose pliers 10, clamp block 11, double V-shaped pincers
Mouth 12, work retainer 20, location mandril 21, angular adjustment knob 22, graduated disc
23, set lever 24, workpiece assembly 30, contiguous block 31, positive stop 32,
The terms such as draw-in groove 33, locating dowel 34, workpiece 100, milling cutter 101, but be not precluded from making
By the probability of other term.Use these terms to be only used to more easily to describe and
Explain the essence of the present invention；Being construed as any additional restriction is all and this
Spirit is contrary.
