Abstract

PROBLEM TO BE SOLVED: To provide an inspection tool for contours of panel work in which even a contour checking piece judged to be out of standard after manufacture can be used as it is. SOLUTION: The contour checking piece of an inspection tool for contours of panel work is supported on a support stand 2 where a frame 2b is erected on a substrate 2a in flat-plate square shape being screwed to a surface plate 1 with a bolt 5 and is arranged around it to inspect the contours of a panel work. One pin insertion groove 1a and two pin insertion grooves 1a for inserting a base part 15a of a positioning pin 15 detachably are formed at one side and the other of peripheral surfaces that are orthogonally crossed at the surface plate part that is located around the peripheral surfaces that are orthogonally crossed of a flat-plate square-shaped substrate 2a. The insertion hole of the bolt 5 of the substrate 2 is made to have a play to displace the bolt insertion position according to a diameter to bring the peripheral surface of a plurality of types of positioning pins 15 where the diameter of the upper part of the base part 15a differs into contact with the peripheral surface of the substrate 2 selectively.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of inspecting the contour of a panel processed product processed by a press or the like mounted on a jig provided on a surface plate. The present invention relates to a figure inspection jig supported by a support table screwed to a surface plate.

[0002]

2. Description of the Related Art FIG. 3 shows an inspection jig of this type, which shows a contour of a processed panel processing product 9 mounted on a receiving jig (not shown) provided on a surface plate 1. FIG. In order to inspect the shape, a figure piece 6 arranged on the periphery is supported by a support base 2 having a frame 2b erected on a flat base 2a screwed to the base 1. The base 2a is positioned by inserting the positioning pins 7 into the grooves formed in the surface plate 1 through the insertion holes 7a, and is screwed with the bolts 5. Thereby, the height of the panel processing product 9 with respect to the surface of the appearance piece 6 is checked, and the gap A between the contour and the peripheral surface of the appearance piece 6 is inspected.

[0003]

However, when machining the figure piece 6, the accuracy of the machining is reduced by, for example, 0.2 mm due to a mistake in the setting of the work material in the NC machine or a drop in the machining.
When the above error occurs, the appearance piece is reworked, or the positions of the insertion hole of the base 2a of the positioning pin 7 and the groove of the surface plate 1 are reworked.

SUMMARY OF THE INVENTION In view of the foregoing, it is an object of the present invention to provide an appearance inspection jig of the kind described above, which can use an out-of-specification appearance piece as it is.

[0005]

In order to achieve the above object, the present invention provides a method for inspecting the contour of a panel processed product mounted on a jig provided on a surface plate. In the inspection jig for appearance where the appearance piece which is supported by the support stand which has the frame set up on the flat base which is screwed to the surface plate with bolts, the peripheral surface orthogonal to the flat base A pin insertion groove for removably inserting the base of the positioning pin is formed on one side and two on the other side of the peripheral surface orthogonal to the base plate located at the periphery of the base plate. The diameter of the upper part of the base is The bolt insertion hole of the base has a play for displacing the bolt insertion position according to the diameter so that the peripheral surface of a plurality of different types of positioning pins can be selectively brought into contact with the peripheral surface of the base. It is characterized by.

[0006] One side is abutting on the orthogonal peripheral surface of the base.
The two positioning pins on the other side define the position of the two-dimensional surface on the surface plate of the support base. When the diameter of the positioning pin changes, the bolt insertion hole having play with respect to the bolt shifts, and the base is displaced to one or both of the directions orthogonal to each other. Therefore, according to the diameter of the positioning pin, it is possible to adjust the end face of the appearance piece on the panel processed product side so as to be entirely within the standard.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An appearance inspection jig according to an embodiment of the present invention will be described with reference to FIGS. In the figure, the same or equivalent parts as those in FIG. An inner diameter in which a base 15a of a positioning pin 15 is removably inserted into a surface plate portion located around the mutually orthogonal peripheral surfaces 10 and 11 of a flat rectangular base 2a of a support 2 screwed to the surface plate 1. One 8 mm pin insertion groove 1a is formed on one peripheral surface 10 side, and two 8mm pin insertion grooves 1a are formed on the other peripheral surface 11 side.

The positions and inner diameters of these pin insertion grooves are such that three positioning pins 15 having a diameter of 8 mm are tightly inserted into the pin insertion grooves 1a in a standard state, and the peripheral surface thereof is
It just comes into contact with 0 and 11. In addition to these standard locating pins, the diameter of the base 15a is commonly set to 8 mm and the upper part is 8 mm in diameter.
A plurality of types are prepared, each of which gradually increases every 0.2 mm with mm as a standard, and each gradually decreases every 0.2 mm from a diameter of 8 mm. Correspondingly, the bolt insertion hole 5a has play in the cross direction for displacing the bolt insertion position in accordance with a change in diameter.

The dimension of the figure piece 6 shown in FIG. 3 becomes narrower or more or less by about -0.3 mm as a whole, for example, to the left as viewed in FIG. In this case, the positioning pin 15 along the peripheral surface 10 having a diameter larger than the standard by 0.6 mm is selected, and the base 15a is inserted into the pin insertion groove 1a. Then, base 2
a is screwed with the bolt 5 in a state where the peripheral surface is set so that the peripheral surface thereof comes into contact with the peripheral surface of the replaced positioning pin 15. As a result, the frame 2b supporting the appearance piece 6 works together with the base 2a, and the peripheral surface of the appearance piece 6 moves to the right by 0.3 mm.
mm so as to occupy a position within an allowable range as a whole. Conversely, when there is an error in the approach direction of the appearance piece 6 in the contour of the panel processing product 9, the one whose diameter is twice as small is selected so that the error is settled within 2 mm.

When the appearance piece 6 has an error in the direction along the peripheral surface 10, the two positioning pins 15 along the peripheral surface 11 correspond so that the end face position in the orthogonal direction generally conforms to the standard. Of the specified diameter. In some cases, three positioning pins 15 are exchanged for two directions orthogonal to each other in a two-dimensional plane.

The appearance piece can be used not only for the outer contour of the panel processed product but also for inspecting the contour of the opening, and the shape can be circular or various corresponding shapes.

[0012]

As described above, according to the present invention, it is possible to easily compensate for the deviation of the shape accuracy of the appearance piece by exchanging the positioning pins of the support table, so that the inspection jig does not need to be repaired and the inspection is performed. Man-hours can be significantly reduced.
