In the centre bore of base, described spring is arranged in the centre bore of base and the top surface of spring withstands on the bottom of alignment pin
On face, described depression bar is arranged on by rotating shaft in the square groove of base, and described lower rounded washers are enclosed on screw and lower circle
Packing ring bottom surface is withstood on the top surface of depression bar, and described upper rounded washers are arranged in the arc groove of lower rounded washers and upper circle
Packing ring is enclosed on screw, and described screw afterbody is arranged in the screwed hole of base and screw is by the through hole on depression bar, described
Base top surface on part is installed and part is enclosed on alignment pin, described pressure head is enclosed on alignment pin and pressure head bottom surface is pushed up
On the top surface of part, described galvanized iron sheet is mounted by means of bolts on the external cylindrical surface of base.
To optimize above-mentioned technical proposal, the concrete measure taken also includes：
Above-mentioned pressure head is made up of cover plate, pin and pressing plate, and described cover plate is fixedly mounted on pressing plate by two pins
On, described cover plate is the disc structure form with rectangle gap, and pressing plate is the structure with rectangular channel.Square on described cover plate
Shape gap and the rectangle gap position consistency on pressing plate.
Above-mentioned depression bar is provided with rectangular channel.
The bottom surface of above-mentioned base is provided with cylindrical boss.
Cover plate on above-mentioned pressure head is made using 45 steel and passes through modifier treatment.
Pressing plate on above-mentioned pressure head is made using brass.
Above-mentioned alignment pin is made using 40Cr and by quenching and temper.
Alignment pin in the invention is provided simultaneously with the function of positioning and compress, and cylinder is matched somebody with somebody with base precision at alignment pin two
Close, coordinate at one with part and complete part positioning；Alignment pin has seal face at two to coordinate and pressing plate cooperation compressing component with depression bar.
The present invention is applied to any process equipment, is positioned especially suitable for more than 4mm small-bores part and fixed.The fixture
Clamping precision is high, is a kind of perfect clamp structure of part machining small positioning.Base evolution groove, possesses integrated hold-down mechanism；
Perimeter is laid out screwed hole, and use is to save fixture flange components.Centre hole of base coordinates alignment pin to slide and ensures to determine
Position pin position degree；There are the cylinder of two and base engagement on alignment pin, wherein being the cylinder of mating parts positioning at one, separately
There is cylinder at one to be used for part positioning and guiding, separately there is keyway at two to be used for and compress block cooperation.Spring is in pin bottom, mainly
It is to make pin increase by elastic force to reset.
The advantage of the invention is that it is following some：
(1) evolution groove can integrate hold-down mechanism in the case where reducing space and occupying on base, mitigate fixture and weigh in itself
Amount；Base integrates flange hole and also saves fixture parts, reduces clamp weight, reduces fixture height, improves clamp precision.Base
Integrated positioning centre bore, the positioning center hole and the processing of the procedure of body one, main advantage is that machining accuracy is higher；
(2) two faces of cylinder of positioning pin directly can coordinate with body positioning hole, and simple in construction, manufacturing cost is low；Pin
For the face of cylinder at two with the cooperation of body central positioning hole at two, ensure to match somebody with somebody while the mechanism reduces cylindricity manufacture difficulty
Precision is closed, while compression can be coordinated, it is compact-sized and there is no consumable accessory.At other one with product coordinate the face of cylinder and with
Upper two faces of cylinder are while grinding forms, and cylindricity is fine, so pack the Positioning Precision Control of fixture in 0.01mm
Within；
(3) compressing structure of the respective outer side edges is fairly simple, and intensity is preferable, can bear maximum 50N/M torsion.
