Abstract

PURPOSE:To improve the precision in positioning the second part for the first part by pressing the first part onto three standard surfaces which are formed onto a jig and are pependicular each other and forming the standard surface of the second part as standard plate onto the jig side. CONSTITUTION:A jig 6 having the first, second, and the third standard surfaces perpendicular each other is installed onto the upper part of a fixed base 5. Positioning is performed by pressing the first part 8 arranged along each standard surface onto the first, second, and the third standard surfaces by the top edges of the first lever 7, second lever 12, and the third lever 15 which is equipped with a compression spring. Then, the second part 19 is arranged onto the upper part of the first part and press-fixed by the fourth lever 18. When the second part 19 is pressed onto a standard plate 23 by a regulating apparatus, etc. in this state, positioning of the second part 19 for the first part 8 is completed. In this case, the standard plate 23 as the standard surface for positioning the second part 19 is pressed onto the plane 26 parallel to the second standard surface of the jig 6 by a pulling spring 25.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a jig for accurately attaching precision parts constituting electronic equipment to other parts.

Structure of the conventional example and its problems The conventional component positioning jig of this type has three reference bins 2 attached to the pace plate 1, as shown in FIGS. 1 to 3. It consisted of a lever 3 that presses and fixes one part on the other, and a lever 4 that holds the other part.

However, in the above configuration, the relative position between the regulating device such as a chuck claw for positioning the second part relative to the first part and the reference bottle 3 is determined by the fact that there are a plurality of parts interposed therebetween. When a large number of jigs are used, variations occur due to cumulative errors. Furthermore, the reproducibility of positioning the first component is poor. This is because in Fig. 1, there is only one lever that fixes the first part, and the force is only applied from the front side to the opposite side, so when taking pictures while the jig is being transported, the part may float or move from side to side. This is because even if a deviation occurs, it will not return to its original state. Furthermore, the accuracy of the regulating device also has a large effect. Due to the above three reasons, the configuration of the conventional example has a drawback in that the positioning accuracy of the second component with respect to the first component is poor.

OBJECTS OF THE INVENTION In view of the above drawbacks, the present invention provides a jig that can accurately position a second component with respect to a first component.

Composition of the invention In the present invention, the first part is the first reference surface of the jig body.

By providing three levers that press down on the second reference plane and the third reference plane, the reproducibility of positioning the first part with respect to the jig is ensured, and the reference plane for positioning the second part is secured. By providing the reference plate on the jig side rather than on the alignment device side, the number of components related to positioning accuracy is minimized, and at the same time, the accuracy of the alignment device is not affected. This eliminates the drawbacks of the conventional example. This has the unique effect of being able to accurately position one component to a second component.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 4 is a plan view of a component positioning jig according to an embodiment of the present invention, and FIG. 5 is a sectional view thereof. In Figs. 4 to 6, reference numeral 6 indicates a fixed pace, and the jig main body 6 is fixed with screws. A first lever 7 presses the first part 8 against the first reference surface of the jig main body 6, and is swingably supported by a pair of bearings 10 via a shaft 9. This first lever 7 has a compression spring 11 interposed between a component holding part at its tip and the jig main body at its rear end. Reference numeral 12 denotes a second lever that presses the component 8 against the second reference surface of the jig main body 6, and is movable in a linear manner via a shaft 13. This second
The lever 12 has a component holding part at the tip and a compression spring 1 at the rear end.

This fourth lever 18 has a component holding part at the tip and a compression spring 22 at the rear end.
through. Reference numeral 23 denotes a reference plate for positioning the component 19, which is movable in a linear manner via a shaft 24. The reference plate 23 has a tension spring 26.

The operation of the component positioning jig constructed as described above will be explained below.

1. When the third lever 16 is pushed open by overcoming the compression spring 17, the lever rotates using the bottle 16 as a fulcrum, and the tip of the lever separates from the component 8. Next, when the shaft 13 is pushed in against the compression spring 14, the tip of the second lever 12 becomes part 8.
move away from When the rear end of the first lever 7 is pressed down against the compression spring 11, the tip of the lever rises with the shaft 9 as a fulcrum and separates from the component 8. Similarly, when the rear end of the fourth lever 18 is pushed down by overcoming the compression spring 22, the shaft 2
The tip of the lever rises with 0 as the fulcrum and separates from the component 19. From this state, when the force applied to the levers 7, 12, and 15 is released in this order, each compression panel causes the tip of each lever to move the part 8 to the first reference plane, second reference plane, and the second reference plane of the jig body 6. 3 Press against the reference surface to position. Next, the component 1 is moved by the compression spring force that releases the force applied to the fourth lever 18.
9 is fixed on part 8. In this state, when the component 19 is pressed against the reference plate 23 using a regulating device or the like, the positioning of the component 19 relative to the component 19 is completed. After positioning is completed, the parts are completely fixed together by means such as gluing,
The work is completed when the rear end of the shaft 24 is pushed open against the tension spring 26, and the levers 7, 12 and 16.8 are released and the parts are taken out.

Effects of the Invention As described above, according to this embodiment, the relative relationship of the first component to the jig is reduced by having three levers that press the first component against the first to third reference planes of the jig body, respectively. position 1
to ensure reproducibility of positioning, and to
By providing the reference plane for positioning the parts on the jig side as a reference plate rather than on the alignment device side, even if there are multiple jigs, the second reference plane of the jig body and the surface in contact with the reference plate can be easily All you need to do is keep the variation in spacing to a minimum,
By reducing the number of component parts related to positioning accuracy to the minimum of one, it is possible to position a part with respect to other parts with high precision.
