A kind of multiaspect drift fine grinding indexing fixture
Technical field
The present invention relates to a kind of fixture, relate in particular to a kind of multiaspect drift fine grinding indexing fixture.
Background technology
The processing on tradition multiaspect drift inclined-plane mainly adopts electric pulse processing, the surface quality of electric pulse processing processing is poor, process-cycle is long, adopts the method for fine grinding, and crudy obtains large increase, but current do not have a kind of for adding the special fixture of holding the multiaspect drift, because drift has a plurality of needs processing, when general fine-grinding fixture often processes a face, adjust the location comparison trouble of drift, not only working (machining) efficiency is low, and machining accuracy is low.
Summary of the invention
The invention provides a kind of multiaspect drift fine grinding indexing fixture, be intended to solve the low problem of existing fine-grinding fixture working (machining) efficiency.
In order to solve above technical problem, the present invention is achieved through the following technical solutions: a kind of multiaspect drift fine grinding indexing fixture, it is characterized in that, comprise the base be connected on the flat stone mill magnetic chuck, be arranged on the index dial of base top, described base and index dial are provided with for setting the indexing means of Different Plane Working position, described base is provided with for the centre hole of base of multiaspect drift is installed, described index dial is provided with and matches with centre hole of base for the index dial centre bore of multiaspect drift is installed, described index dial centre bore is coaxial with centre hole of base, on described index dial, also be provided with for the multiaspect drift is locked to the locking device on index dial.
Further, described indexing means comprises for connecting the latch of base and index dial, the base pin hole that is positioned at the base upper end and matches with latch, at least three index dial pin holes that evenly arrange on one circumference of index dial, described index dial pin hole is identical to the distance of the central axis of base with the base pin hole to the distance of the central axis of base, while being convenient to process not coplanar, the multiaspect drift can be set in to corresponding Working position.
Further, described index dial pin hole has eight, for processing the octahedral drift.
Further, described latch is the magnetic force latch, can increase the active force to index dial and base of latch, and stability strengthens.
Further, described locking device comprise along the index dial radial direction through the screwed hole of index dial sidewall and with the clamping screw that screwed hole matches, be convenient to index dial and multiaspect drift are tightened together, thereby drive the multiaspect drift when index dial is rotated, rotate together.
Further, described base is fixed together by magnetic force and flat stone mill magnetic chuck, is convenient to installation and removal.
Further, the angle between the center line of described base and flat stone mill magnetic chuck upper surface is acute angle, is convenient to the multiaspect drift and adds a suitable angle is arranged man-hour.
Comparing advantage of the present invention with existing fine-grinding fixture is: the present invention is provided with index dial, rotate index dial, when each index dial pin hole is fixed on the base pin hole, the Working position on a corresponding drift plane, make like this working (machining) efficiency on drift plane high, and machining accuracy is high.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described:
Fig. 1 is structural representation of the present invention;
The A that Fig. 2 is Fig. 1 is to view;
The structural representation that Fig. 3 is index dial.
The specific embodiment
Consult Fig. 1, Fig. 2 and Fig. 3, a kind of multiaspect drift fine grinding indexing fixture, comprise the base 2 be connected on flat stone mill magnetic chuck 1, be arranged on the index dial 3 of base 2 tops, described base 2 and index dial 3 are provided with for setting the indexing means of Different Plane Working position, described base 2 is provided with the centre hole of base 21 for multiaspect drift 5 is installed, described index dial 3 is provided with and matches with centre hole of base 21 for the index dial centre bore 31 of multiaspect drift 5 is installed, described index dial centre bore 31 is coaxial with centre hole of base 21, on described index dial 3, also be provided with for multiaspect drift 5 is locked to the locking device on index dial 3, described indexing means comprises for connecting the latch 4 of base 2 and index dial 3, the base pin hole 22 that is positioned at base 2 upper ends and matches with latch 4, at least three index dial pin holes 32 that evenly arrange on one circumference of index dial 3, described index dial pin hole 32 is identical to the distance of the central axis of base 2 with base pin hole 22 to the distance of the central axis of base 2, described index dial pin hole 32 has eight, described latch 4 is the magnetic force latch, described locking device comprises along index dial 3 radial direction through the screwed hole 33 of index dial 3 sidewalls and the clamping screw 6 matched with screwed hole, described base 2 is fixed together by magnetic force and flat stone mill magnetic chuck 1, angle between the center line of described base 2 and flat stone mill magnetic chuck 1 upper surface is acute angle.
During installation, base is adsorbed on the flat stone mill magnetic chuck, the multiaspect drift is inserted in the index dial centre bore, with clamping screw, multiaspect drift and index dial are locked, then by the non-processing end of multiaspect drift inserted base centre bore, rotation-indexing table until wherein one division dish pin hole with the base pin hole, align, latch is inserted in index dial pin hole and base pin hole successively.
After installation, first process a face with emery wheel, after processing, the taking-up of pulling pin, rotation-indexing table until next index dial pin hole with the base pin hole, align, then insert latch, with emery wheel, process a machined surface corresponding with its position, then repeat a process until process all faces.
The present invention is provided with index dial, rotates index dial, and when each index dial pin hole is fixed on the base pin hole, the Working position on a corresponding drift plane, make like this working (machining) efficiency on drift plane high, and machining accuracy is high.
The foregoing is only specific embodiments of the invention, but technical characterictic of the present invention is not limited to this, any those skilled in the art is in the field of the invention, and the variation of doing or modification all are encompassed among the scope of the claims of the present invention.
