Abstract

The utility model discloses a combined fixture component comprising a bottom plate and a top plate. One end of the bottom plate and one end of the top plate are hinged together through a fixed shaft. A moving shaft is fixed at the other end of the bottom of the top plate. A distance from the center of the fixed shaft to that of the moving shaft is A. A vertical distance from the center of the moving shaft to the bottom plate is H. H=A*sin alpha, and alpha refers to the included angle between the upper surface of the bottom plate and the lower surface of the top plate. The bottom of the bottom plate is provided with a plurality of standard key grooves of a groove-system combined fixture. The top surface of the top plate is provided with a plurality of standard cross meshed T-grooves of the groove-system combined fixture. The combined fixture component has the advantages of flexibility and convenience of positioning in the groove-system combined fixture, meets the positioning requirements of parts to be machined, with various fixation angles, and is convenient to use.

Description

A kind of built-up jig assembly

Technical field

The utility model relates to a kind of built-up jig assembly.

Background technology

Groove is that built-up jig is that seriation, standardized component by a series of pre-manufactured difformity different size specifications and difference in functionality assembles, the keyway that has standard on its bottom surface, can be connected or be connected with lathe with other built-up jig base components easily; The netted T-shaped groove of cross that has standard on surface, bolt is walked freely in the netted T-slot of cross, easy to adjust, is easy to meet the clamping requirement of special-shaped part, can coordinate other built-up jig or different lathes to use.Existing groove is that built-up jig can be located by fine clamping for various straight-line dimension parts to be processed; Part to be processed for fixed angle size only has the part to be processed that fixed angle size is identical with the angle of its inclination supporting component to locate by fine clamping, for different can not the locating by clamping of angle, namely existing groove is that built-up jig can not can meet positioning requirements to the part to be processed of various fixed angle sizes, and it has significant limitation.

Summary of the invention

The purpose of this utility model solves the above-mentioned problems in the prior art exactly, a kind of built-up jig assembly is provided, it is flexible that this assembly had both had advantages of that groove was that built-up jig is located, and can meet again the advantage of positioning requirements of the part to be processed of various fixed angle sizes.

For achieving the above object, technical solution of the present utility model is: a kind of built-up jig assembly, and it comprises base plate and panel; One end of base plate and panel is hinged by fixed axis, and the other end of panel bottom surface is fixed with movable axis; Distance between the center of fixed axis and the center of movable axis is A, and the center of movable axis and the vertical range between base plate are H, H=Asin α so, and α is the angle between plate upper surface and panel lower surface; On the bottom surface of base plate, have a plurality of grooves and be the keyway of the standard having on built-up jig, on the surface of panel, have a plurality of grooves and be the netted T-shaped groove of cross of the standard having on built-up jig; On the surface of base plate and the bottom surface of panel, have corresponding support slot.

On base plate described above and the wall of panel, have fixing hole.

During use, keyway by standard on the utility model base plate bottom surface base plate of the present utility model is fixed in other built-up jig base components or with lathe on, the netted T-shaped groove of cross by processed workpiece by standard on panel is clamped on its panel surface.According to the distance A between the processed angle on workpiece inclined plane and the center of fixed axis and the center of movable axis, calculate the center of movable axis and the vertical range H between base plate, according to the height dimension of the good cushion block of the size Selection of H, by cushion block pad between movable axis and base plate, the in the situation that of needs, by the support slot on base plate and panel, skew support again, so that the utility model keeps more firm supporting and location.It is flexible that the utility model had both had advantages of that groove was that built-up jig is located, as long as change the size of cushion block height, just can obtain the α angle of various numerical value, so it can meet the positioning requirements of the part to be processed of various fixed angle sizes again.Very easy to use.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is further described.

As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the present embodiment comprises base plate 3 and panel 1.One end of base plate 3 and panel 1 is hinged by fixed axis 4, and the other end of panel 1 bottom surface is fixed with movable axis 2.Distance between the center of the center of fixed axis 4 and movable axis 2 is A, and the vertical range between the center of movable axis 2 and base plate 3 is H, H=Asin α so, and α is the angle between base plate 3 upper surfaces and panel 1 lower surface.On the bottom surface of base plate 3, have a plurality of grooves and be the keyway 6 of the standard having on built-up jig, on the surface of panel 2, have a plurality of grooves and be the netted T-shaped groove 5 of cross of the standard having on built-up jig.On the surface of base plate 3 and the bottom surface of panel, have

corresponding support slot

9,10, Qi Bishang has fixing hole 7,8.During use, then fixed by cushion block 11 and the bearing diagonal of corresponding height.

As shown in Figure 5, the present embodiment is identical with example structure as shown in Figure 1, Figure 2, Figure 3 and Figure 4, and one end that just base plate is connected by fixed axis with panel is hinged by hinge 11.
