Abstract
The invention belongs to the technique field of the machinery process, and in particular relates to a small hole middle mould taper grinding device. Solving the problem of the prior art that the middle mould taper grinding device cannot be fixed tightly and the processing precision is low. The small hole middle mould taper grinding device comprises a high speed grinder and a clamp, the high speed grinder has a milling head, the clamp is provided with an expanded clamp head assembly, the end of the expanded clamp head assembly is inserted in the middle mould to be fixed together with the middle mould. The structure is simple, the process is convenient, the expanded clamping mode is firm and reliable, and the work efficiency and the middle mould grinding precision are improved.
Description
Technical field
The invention belongs to Machining Technology field, relate to mould taper grinding device in a kind of aperture.
Background technology
In abrasive machining device in machining device, for mould taper grinding device in aperture, adopt scroll chuck to clamp middle mould often, then grind with high-speed grinder, by the angular compliance between scroll chuck and high-speed grinder, grinding goes out the tapering of middle mould.Scroll chuck during mould, easily makes the surface damage of middle mould in clamping, the fineness on mould surface in impact; In addition, when mould carries out rotary grinding in clamping, easily there is position cheap, cause machining accuracy to be affected in scroll chuck.
In order to overcome the deficiencies in the prior art, people have passed through continuous exploration, propose various solution, as Chinese patent literature discloses a kind of vertical shaft type taper grinding device [patent No.: CN102476329B], it has transverse feed mechanism, cross slide, vertical feeding mechanism, vertical saddle, slew gear, Vertical Mill head, its back side of described cross slide is connected with transverse feed mechanism, and frontal design is box shell structure, and inside is provided with slew gear; Described slew gear is arranged between cross slide and vertical saddle; Slew gear has swivel mounting member, and swivel mounting member is circumscribed with brake hoop, is connected above described brake hoop with machine rotary tray, side and hydraulic locking attached components.
Such scheme need not widen emery wheel, can reduce production cost; The steep-taper of vertical shaft form, long tapering part can be processed, tapered surface roughness and machining accuracy can be improved, improve grinding efficiency.But program complex structure and can not be used for processing in mould tapering.
Summary of the invention
The object of the invention is for the problems referred to above, mould taper grinding device in the aperture that a kind of structure is simple, firm grip, grinding accuracy are high is provided.
For achieving the above object, present invention employs following technical proposal: mould taper grinding device in a kind of aperture, comprise high-speed grinder and fixture, described high-speed grinder has bistrique, described fixture is folded with collet expander assembly, the end of described collet expander assembly to be inserted in middle mould and to expand fixing with middle mould.
In above-mentioned aperture in mould taper grinding device, described fixture is scroll chuck, described collet expander assembly comprises and is folded in collet expander body in scroll chuck and the expansion-head affixed with collet expander body end, and described expansion-head to be inserted in middle mould and to expand fixing with middle mould.
In above-mentioned aperture in mould taper grinding device, described collet expander body is cylindrical.
Compared with prior art, the invention has the advantages that: structure is simple, easy to process, the fixation of expansion method of clamping is reliable, improves the precision of operating efficiency and the grinding of middle mould tapering.
Accompanying drawing explanation
Fig. 1 is structural representation provided by the invention;
Fig. 2 is the structural representation in another direction provided by the invention.
In figure: high-speed grinder 10, bistrique 11, fixture 20, scroll chuck 21, collet expander assembly 30, collet expander body 31, expansion-head 32, middle mould 100.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention will be further described in detail.
As depicted in figs. 1 and 2, mould taper grinding device in a kind of aperture, comprise high-speed grinder 10 and fixture 20, described high-speed grinder 10 has bistrique 11, described fixture 20 is folded with collet expander assembly 30, and the end of described collet expander assembly 30 to be inserted in middle mould 100 and to expand fixing with middle mould.
The present invention, is gripped by the mode centering mould 100 expanding fixing, and fixing reliable, working (machining) efficiency is high, and precision is high.
Preferably, fixture 20 is scroll chuck 21, described collet expander assembly 30 comprises and is folded in collet expander body 31 in scroll chuck 21 and the expansion-head 32 affixed with collet expander body 31 end, collet expander body 31 is cylindrical, and described expansion-head 32 to be inserted in middle mould and to expand fixing with middle mould.
The course of work of the present invention is:
Be inserted in expansion-head 32 by the die cavity of middle mould 100, in the diameter ratio of expansion-head 321, the little 1-3 silk of die cavity of mould 100, drops in expansion-head 32 with setscrew after insertion, and expansion-head 32 is coordinated with middle mould swelling, and also namely middle mould 100 is fixed with expansion-head 32.When scroll chuck 21 rotates, in drive, mould 100 rotates, and high-speed grinder 10 is with rotary bistrique 11 High Rotation Speed.Angulation between scroll chuck 21 and bistrique 11, bistrique 11 can form tapering grinding by centering mould 100.
Structure of the present invention is simple, easy to process, and the fixation of expansion method of clamping is reliable, improves the precision of operating efficiency and the grinding of middle mould 100 tapering.
Specific embodiment described herein is only to the explanation for example of the present invention's spirit.Those skilled in the art can make various amendment or supplement or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present invention or surmount the scope that appended claims defines.
Although more employ the terms such as double acting flat-nose pliers 10, clamp block 11, double V-shaped jaw 12, work retainer 20, location mandril 21, angular adjustment knob 22, dial 23, set lever 24, workpiece assembly 30, contiguous block 31, positive stop 32, draw-in groove 33, locating dowel 34, workpiece 100, milling cutter 101 herein, do not get rid of the possibility using other term.These terms are used to be only used to describe and explain essence of the present invention more easily; The restriction that they are construed to any one additional is all contrary with spirit of the present invention.
