Abstract
The utility model relates to a self-aligning pressing plate which is suitable to machine tool processing, comprising presser feet (1), a pressing strip (2), pressing blocks (3), a shore (4) and stabilizers (5). The pressing strip (2) is two blocks of parallel lathes which are arched lathes, the shore (4) is served as a connecting fastener in the bore (6) and the bore (7) of the arched lathes to connect and fix the two parallel lathes, and the presser feet (1) with axial steps and the stabilizers (5) are arranged in the two end openings of the arched lathes. The pressing blocks (3) are arranged in the bores (8) of the vault positions of the two parallel arched lathes, the pressing blocks which are provided with center bores are stepped shafts, erect pressure screw bolts (9) are arranged in the center bores, and the upper ends of the screw bolts are provided with nuts (10). The utility model and a bed have major technical economy effects on the utility model is simple in structure, few in parts, reasonable in stress division, few in materials input, large in pressure contact face and no in workpiece damage.
Description
The utility model relates to a kind of pressing plate of positioning certainly that is used for machine tooling.
Chinese patent 88216363.9 proposes a kind of pressing plate that makes things convenient for, the pressing plate body of pressing plate is made of two cant boards and connector, the connector of pressing plate body two ends contacts with workpiece with the semi-cylindrical surface, has the semi-circular recesses that several are parallel and radius equates to match with the half-cylindrical part of hinged beam two ends above the pressing plate body.Though this patent improves to some extent with pressing plate to original lathe, but also have following not enough, the one, be the face of cylinder with the workpiece contact portion with the bed surface contact portion, be in the unstable state of pressurization probably, the 2nd, the semi-cylindrical recesses place is the maximum force place, must cause the bad distribution of stress to cause waste material.
Task of the present utility model is to improve above-mentioned deficiency, provide a kind of materials reasonable, simple in structure from the pressure regulation pressing plate.
The technical solution of the utility model is: from the pressure regulation pressing plate by presser feet (1), press strip (2), briquetting (3), dagger (4) and leg (5) are formed, press strip (2) has two, be two blocks of parallel battens, batten is the arch form batten, having dagger (4) to connect securing member in the hole (6) of arch form batten and hole (7) is connected and fixed two parallel-plates, presser feet (1) and leg (5) that the step shaft type is arranged in two stomidiums of arch form batten, in the hole (8) of the arch crown part of two parallel arch form battens, briquetting (3) is arranged, briquetting (3) is the step axle, centre bore is arranged, the pressure bolt (9) that Kong Zhongyou is upright, there is clamp nut (10) the double-screw bolt upper end.
Because the utility model separates leg (1), presser feet (5) with connector, the contact point of pressure spot and workpiece and bed surface makes face into by point, line, the contact pressure stability, the phenomenon of bed surface and surface of the work can not appear weighing wounded, increased briquetting (3), briquetting is the step axle, and the pressure bolt is arranged in the centre bore, pressing plate has associative perception, the stressed distribution of arch form plate is reasonable, the material saving weight reduction, press defend stable, simple in structure, processing is simple, cost is low, finish the invention task.
Be described in detail the utility model below in conjunction with accompanying drawing.
Fig. 1 is enforcement of the present utility model and application examples.
Fig. 2 is the embodiment of the utility model arch form batten.
Fig. 3 is the vertical view after arch form batten and each step axle and the dagger combination.
Press strip (2) is that arch form plate (Fig. 1, Fig. 2) can be I shape for the weight reduction cross section, the arch form plate has two, be connected and fixed by two daggers (4) abreast, presser feet (1) is the step axle with leg (5), boss can be a non-cylindrical, can be square shape, can be circular upper part and square lower part also, be that the lower surface is the plane, the upper surface can have any shape, as sphere shape, ellipsoid shape or plane or the like (Fig. 3).Presser feet (1) can be done the plane rotation around self axle.Can guarantee that like this pressure face of presser feet (1) and the compression face of workpiece keep closely connected, increase compression face, reduce compression.Presser feet (1) can be to be slidingly matched to get final product by axle and cooperating of hole then around self axle rotation.Also presser feet (1) can be resolved into two compositions of axle and cover, protruding presser feet (1) is to be enclosed within on self axle, freely rotates again and gets final product.Leg (5) also can be designed to do the plane around self axle and rotate, and method for designing is identical.Briquetting step axle (3) is arranged in the vault hole of arch form plate, and the projection of briquetting step axle can be square, and rectangle or the like has centre bore, is erectly plugging in depression bar bolt (9) in the hole, and nut (10) is arranged at the top of bolt.During use, depression bar bolt (9) lower end is fixed on the bed surface, and nut (10) acts on briquetting (3) with pressure, thereby leg (5) is pressed on bed surface, and presser feet (1) compresses workpiece (11).
Because presser feet (1) can rotatablely move as the plane around self axle, presser feet (1) can be adjusted automatically with the force position of workpiece, guarantees maximum contact-making surface, adds that leg also can be around self axle rotation, increased the amplitude of adjusting, briquetting boss (3) also can be designed to rotatablely move as the plane around self axle.
The lower surface of presser feet (1) can be the plane, and it is applicable to that the workpiece contact-making surface is the state on plane.Can there be V-shaped groove the lower end of presser feet, is applicable to round piece.Leg (5) is owing to directly be contacted with the lathe bed plane, and the lower surface is the plane.Avoided pressure spot stress excessive and cause damaging the lathe bed plane like this.
Because presser feet (1), leg (5) can be around self axle rotations, can adjust the pressurized state with workpiece automatically, guarantee the maximum pressurization contact-making surface and the stability of pressurization, avoided weighing wounded workpiece and lathe bed again.The utility model is because novel in design, in addition part few, simple in structure, demonstrate its superior techno-economic effect.
