Description
Technical field
The utility model relates to a kind of fixture quick replacement device.
Background technology
At present, domestic mechanical processing industry major part has realized machining center Flexible Production, the product diversification of Cutter Body Processing with Machining Center, and special fixture is also diversified.When machining center needs to process dissimilar product, just need to change fixture.Once after clamp-replacing, to need its position on the table again centering and fixing.Just spend certain hour like this on fixture centering when switching product, and higher to the skill set requirements of workman, and the level of the accuracy that fixture centering is also fixing and operator has much relations.Have impact on the practical efficiency of machining center, be no matter equipment or artificial, all cause waste.When particularly work in-process debugs a kind of new product in the heart, often adopt the method for examination processing because of debugging clamper, be easy to like this cause product rejection, cause entreprise cost to rise.
Summary of the invention
The purpose of this utility model is to provide a kind of simple to operate, and accurate positioning, not by the machining center clamp quick replacement device that craftsmanship affects.
Technical solution of the present utility model is: comprise the base plate between workbench and fixture, base plate has two or more and connect counterbore, two or more locating hole, two or more installing hole, for by base plate, the bolt be loaded on workbench is loaded on connection counterbore place, fastening screw for positioning fixture is loaded on locating hole place through lining, for the screw of clamp pressing on base plate is loaded on installing hole place.
Described connection counterbore is kidney-shaped counterbore.
Described installing hole is screwed hole.
The described base plate side of being plate, connecting counterbore is four, be distributed in base plate corner place, the connection counterbore outward flange in the upper left corner to the distance of base plate top edge is greater than the distance of connection counterbore outward flange to base plate top edge in the upper right corner, and the connection counterbore outward flange in the lower left corner to the distance of base plate lower limb is less than the distance of connection counterbore outward flange to base plate lower limb in the lower right corner.
Described lining and locating hole are interference fits.
Described fastening screw be divided into be positioned at fixture upper surface epimere, with the friction tight truncated cone-shaped stage casing of fixture, the hypomere that coordinates with sleeve clearances.
Fixture is placed on base plate, to be coordinated ensure that fixture opposed bottom is each all at the same relative position by fixture from locating hole with it, lining and fastening screw three, so ensure fixture each all with workbench at the same relative position.
The utility model specifically one can switch machining center clamp fast, and ensures that fixture is changed position that is rear and workbench at every turn and immobilized, and saves a kind of device of centering fixture time.The utility model solves when changing machining center clamp long to machining center clamp alignment time, the problem high to the skill set requirements of workman.Machining center is realized quick when switching fixture, accurate, efficient by this device, reduce the skill set requirements to workman, save the time switching fixture, very high repetitive positioning accuracy can be ensured again simultaneously, increase work efficiency in the process of producing, reduce artificial origin and make the mistake, ensure the switching time of different product in process, improve machining center by rate, obtain and apply very widely.Compared with prior art to have structure simple for the utility model, accurate positioning, processing ease, to craftsmanship require low, the feature such as to raise the efficiency.

Detailed description of the invention
In Fig. 1,2,3, base plate 1 has two locating holes 3, locating hole 3 is built with lining 2, fitted lining cover 2 is to change after using wearing and tearing, and lining 2 and locating hole 3 are interference fits, and fastening screw 4 is divided into three sections, epimere is positioned at fixture upper surface, and stage casing is loaded in fixture installing hole, and hypomere is loaded in lining 2.Fastening screw 4 hypomere and lining 2 are matched in clearance, fastening screw 4 stage casing and fixture mating part with tapering, to realize high-precision location.On base plate 1 also have four connecting holes 5, be connected with machining center workbench 8 and compress through bolt 7, make base plate 1 and workbench 8 relative position constant.Base plate 1 there is screwed hole 6, be connected with machining center clamp 9 and through screw in compression, the lining 2 on fixture 9 and base plate 1 can be made to be assembled together by fastening screw 4, ensure that fixture 9 and base plate 1 are at every turn all at same relative position.
In Fig. 4,5,6, on base plate 1 work in-process heart workbench, behind centering position, bolt is by connecting counterbore 5 and workbench compression.Fast replacing device is put on the table, does not dismantle to ensure that fast replacing device and workbench relative position immobilize.Machining center clamp also has two locating holes, two locating hole 3 relative positions on its relative position size and base plate 1 are measure-alike, locating hole on fastening screw 4 stage casing and fixture coordinates, and ensures that machining center clamp and fast replacing device relative position immobilize.Fastening screw 4 stage casing coordinated with locating hole on machining center clamp, with certain tapering, like this when fastening screw 4 hypomere inserts in lining 2, can be got rid of the fit clearance between machining center clamp and this device, make location more accurate.Like this, machining center clamp change at every turn after without centering, can ensure that the relative position of machining center clamp and machining center workbench immobilizes by the utility model.
Design theory of the present utility model fixingly behind base plate and machining center workbench centering position not to dismantle, the locating hole on the utility model just and workbench ensure to immobilize at relative position.Fixture has two locating holes identical with the utility model relative position, fixture is fixed by the lining on the utility model base plate and fastening screw, make itself and machining center workbench relative position constant, after changing fixture, directly carry out centering fixture by fastening screw.
