Abstract
The utility model relates to a special clamp for drilling on a wing-type universal joint bearing seat with inner base location as required by design. A die core is installed on the base plate, a positioning keyway is located on the location plate beside the die core and the location keyway is provided with a guide hole parallel to a guide-drilling sleeve on both sides. Therefore, the utility model has features has reasonable structure, the drilling position has exact distance to the inner base. The utility model has advantages of high and stable quality, easy production and operation, high efficiency, enhanced manufacture quality and elongated service life.
Description
The utility model relates to a kind of clamping tool for machine work, especially relates to a kind of special fixture of holing by designing requirement on the aerofoil profile cardan axis bearing that adopts the inner bottom surface location.
In order to improve work efficiency and crudy, people had once carried out many improvement to boring grab.For example, the someone has applied for the utility model patent of " workpiece fixture for drilling and threading " (application number is 91223833.X) by name.It is as a kind of workpiece fixture for drilling and threading, by positioning core axle, being assemblied in the quick change cover of mandrel inwall and the annex of clamping cutter forms, the inwall that it is characterized in that positioning core axle is conical, the outer surface of quick change cover also is conical, the outer surface of quick change cover is installed on the inwall of positioning core axle, on the wall of the same diameter of positioning core axle, have 3 to 6 equidistant holes, quick change overlaps place, corresponding above-mentioned hole and drives 3 to 6 holes or a cannelure, in the inside, the hole of each cooperation (or groove) one steel ball is set all, outer surface pine cover one movable sleeve at positioning core axle, have a cannelure in the bottom of movable sleeve, so that during dismounting, steel ball is fallen in the groove, and at outer wall pine cover one handling ring of quick change cover, handling ring is by being fixed on back-up ring in the quick change cover and blocking and not gliding.But it is comparatively complicated to exist structure, and it is very not convenient to operate, and is difficult to be applied to the deficiencies such as boring of aerofoil profile bearing convex surface.
Goal of the invention of the present utility model is to overcome the deficiencies in the prior art, provides a kind of rational in infrastructure, and bore position and inner bottom surface relative distance are accurate, easy to operate, end location drilling anchor clamps in the bearing block of long service life.
Goal of the invention of the present utility model mainly is achieved by following technical proposals: be provided with core rod on described base plate; On the other location-plate of described core rod, be provided with positioning spline, and be provided with pilot hole parallel to each other in the both sides of described positioning spline.Described location-plate can be made with base plate integral body, is combined into one after also can making respectively; Described core rod can adopt the pin key close-fitting to be integral, and also can adopt modes such as spiral connection to be arranged on the base plate.
It is protruding that the lower end of described location-plate is provided with connection, is embedded on the corresponding pedestal of base plate, adopts bolt to fix; The outside at described location-plate is provided with back seat plate, and is provided with in the inside of described pilot hole and leads drill bushing.Usually, the area of described back seat plate is less, is advisable to be suitable for further fixedly leading drill bushing.
In order further to improve the quality of service life of the present utility model and product to be processed, adopt the hard steel to make at the described drill bushing of leading, its outer face is higher than the back seat plate surface, and by placing the hold-down screw on the back seat plate side fixedly to lead drill bushing; And, be provided with the cooling import that links to each other with coolant pipe leading near the drill bushing near-lying mode core side ports.Like this, can also make cooling fluid continue to enter drill bit drilling place, in time drill bit be cooled off.
Be the T type at described base plate, its both wings lower edge and central convex body are provided with dowel hole; And be provided with dowel hole in the bilateral symmetry of location-plate.Be beneficial to described base plate and location-plate and workbench firmly, stably be connected.
Characteristics such as therefore, the utlity model has rational in infrastructurely, bore position and inner bottom surface relative distance are accurate, and product quality is high and stablize, produces, operates and carry out substantially automatically except that workpiece loading and unloading, and is convenient, efficient; Simultaneously, the structure of leading drill bushing and so on is more conducive in time change lead drill bushing, improves the service life of product processing quality and these anchor clamps.
Accompanying drawing 1 is the structural representation that a kind of master of the present utility model looks;
Accompanying drawing 2 is structural representations of a kind of backsight of the present utility model;
Accompanying drawing 3 is a kind of side-looking structural representations of the present utility model.
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: be provided with the core rod seat on base plate 6 axis, core rod 8 is placed on it, and tightens the hold-down screw 12 that places therebetween, makes it fixing by placing nut 18 under it abaculus of screw thread (or be provided with) to tighten.Side at base plate 6 is provided with pedestal, is embedded with on it that to be located at the corresponding with it connection in location-plate 4 lower ends protruding 11, and adopts several bolting to be integral; Be provided with the back seat plate 9 of using bolting in the outside of described location-plate 4, make itself and location-plate 4 be fixed into one.Be provided with positioning spline 3 on the axis of location-plate 3, its bilateral symmetry is provided with two pilot holes 5, is provided with in the hole by what the hard tool steel was made and leads drill bushing 15; Inserting the drill bushing hold-down screw of being tightened by side direction the back 14 fixes.And, be provided with the cooling import 13 that links to each other with coolant pipe leading near drill bushing 15 near-lying mode cores 8 side ports, make cooling fluid directly enter cutting place of drill bit and workpiece.Base plate 6 is the T type, and its both wings lower edge and central convex body 7 are provided with dowel hole 2; And be provided with dowel hole 2 in the bilateral symmetry of location-plate.The utility model is fixed on the ring flange of lathe thus.
During operation, workpiece 1 is placed on the core rod 8, and its key body inserts in the positioning spline 3 of location-plate 4.Then, the presser feet of lathe is fixed on it on core rod 8 tightly from the outside and the top of workpiece 1 automatically.Because the peristoma of workpiece 1 breaks away from the lower edge of core rod, the upper surface of core rod 8 is depended in the location of workpiece 1, it is the inner bottom surface of workpiece 1, as datum level, adopt the drill bit of debugging in advance, fixing, under the drill bushing guiding of hard, pierce the convex surface of workpiece 1, and under the continuous cooling of the liquid of importing from cooling liquid inlet 13, drill bit is successfully finished the operation of cutting boring.Therefore, during with the utility model processing work, work efficiency is high and do not have accumulated error and take place.
