Description

TECHNICAL FIELD The present invention relates to a measurement auxiliary jig used when measuring a relative positional relationship between two different points on a vehicle body.

BACKGROUND ART When measuring the relative positional relationship between two different points on a vehicle body, a step caliper (also referred to as a step gauge) may be used as described in Patent Document 1, for example. That is, for example, when confirming whether or not a door of a vehicle is installed correctly, stepped calipers are applied to both a portion of the door and a portion of the nearby vehicle body or another portion of the door. The size of the steps and gaps between the two is confirmed by placing them against each other.

However, depending on the part to be measured of the vehicle body, the part to be measured may have a curved shape or a complicated shape. Therefore, it is by no means easy to measure the relative positional relationship by bringing the stepped caliper into direct contact with the location to be measured, and there are cases where it is difficult to obtain accurate measurement values. Such a problem may occur not only when using step calipers but also when using other measuring instruments.

SUMMARY OF THE INVENTION The present invention has been made in view of such problems, and an object thereof is to provide a measurement auxiliary jig that enables easy and accurate measurement of the relative positional relationship between two different points on a vehicle body. be.

(Embodiment 1)
An embodiment of the measurement auxiliary jig will be described with reference to FIGS. 1 to 9. FIG.
As shown in FIG. 1, the auxiliary measurement jig 1 of this embodiment is used when measuring the relative positional relationship between two different points on the vehicle body 8 (for example, points indicated by reference numerals 81 and 82 shown in FIGS. 2 and 3). It is used for

As shown in FIGS. 1 and 4 , the measurement aid 1 has a first jig 10 and a second jig 20 .
Each of the first jig 10 and the second jig 20 has mounting fixing portions 11 and 21 and contact planes 12 and 22 . The mounting/fixing portions 11 and 21 are portions for mounting and fixing to the measurement points 81 and 82 of the vehicle body 8 . The contact planes 12 and 22 are surfaces for contacting the measuring device 7 .

As shown in FIG. 1, in a state in which the first jig 10 and the second jig 20 are attached and fixed to the respective locations 81 and 82 to be measured, the contact plane 12 of the first jig 10 and the second jig The abutting planes 22 of 20 are arranged on the same plane or parallel to each other. In this embodiment, the contact plane 12 of the first jig 10 and the contact plane 22 of the second jig 20 are arranged on the same plane. However, the contact plane 12 of the first jig 10 and the contact plane 22 of the second jig 20 are arranged parallel to each other at positions shifted by a predetermined dimension in the normal direction. It can also be assumed that there is This is because, if the predetermined dimensions are as designed, the inspection results show that the vehicle body is assembled accurately.

It should be noted that "in a state in which the first jig 10 and the second jig 20 are attached and fixed to the respective measured points 81 and 82" here means that the two measured points 81 and 82 are in a state as designed. It is assumed that it is formed by

In this embodiment, the two measured points 81 and 82 are part of the front door 810 and part of the rear door 820 of the vehicle body 8, as shown in FIGS. More specifically, the portion to be measured 81 is a portion behind the portion along the lower side of the window frame of the front door 810, and the portion in front of the portion along the lower side of the window frame of the rear door 820 is to be measured. It is point 82 .

As shown in FIGS. 5 to 9, these points to be measured 81 and 82 have complicated shapes in detail, and have curved surface shapes in which various curved surfaces are combined. The first jig 10 and the second jig 20 of the measurement auxiliary jig 1 are attached and fixed to these measurement points 81 and 82, respectively. In this embodiment, the first jig 10 is attached and fixed to the measured portion 81 of the front door 810 , and the second jig 20 is attached and fixed to the measured portion 82 of the rear door 820 . At this time, the first jig 10 is attached and fixed to the measured portion 81 by the attaching and fixing portion 11 . Also, the second jig 20 is mounted and fixed to the measurement target location 82 by the mounting and fixing portion 21 .

For example, as shown in FIGS. 4 to 7, the first jig 10 includes a clamping portion 11a (see FIG. 5) that clamps a part of the portion 81 to be measured, and a part of the portion 81 to be measured as the mounting fixing portion 11. 6), a fitting portion 11c (see FIG. 7) that fits into a hole provided in a part of the measured portion 81, and the like. For example, positioning in the vehicle width direction Y is mainly performed by the holding portion 11a, positioning in the vehicle vertical direction Z is mainly performed by the contact portion 11b, and positioning in the vehicle longitudinal direction X is mainly performed by the fitting portion 11c. will be However, the positioning in the vehicle width direction Y, the vehicle up-down direction Z, and the vehicle front-rear direction X may be performed by the mounting fixing portion 11 as a whole. In addition to these, the first jig 10 can also be configured to function as the attachment/fixing portion 11 by abutting on a part of the portion 81 to be measured.

For example, as shown in FIGS. 4, 8, and 9, the second jig 20 includes a holding portion 21a (see FIG. 8) for holding a portion of the measurement target portion 82 as the mounting fixing portion 21, It has a contact portion 21b (see FIG. 9) that contacts a portion of the measurement point 81, and an insertion portion 21c (see FIG. 9) that fits into a hole provided in a portion of the portion 81 to be measured. As shown in FIG. 4, the second jig 20 is provided with two holding portions 11a and two fitting portions 21c.
The first jig 10 and the second jig 20 can be made of resin, for example.

Next, the effects of this embodiment will be described.
The measurement auxiliary jig 1 has the first jig 10 and the second jig 20 configured as described above. As a result, in a state in which the first jig 10 and the second jig 20 are attached and fixed to the vehicle body 8, the contact plane 12 of the first jig 10 and the contact plane 22 of the second jig 20 are aligned in two directions. They are arranged so as to have a relative positional relationship corresponding to the relative positional relationship of the measured points 81 and 82 of the points. In this state, as shown in FIG. 1, by bringing the measuring instrument 7 into contact with the respective contact planes 12 and 22, the relative positional relationship between the two contact planes 12 and 22 can be easily and accurately measured. can do. This measurement result reflects the relative positional relationship between the two measured points 81 and 82 . Therefore, the relative positional relationship between the two measured points 81 and 82 can be measured easily and accurately.

When the front door 810 and the rear door 820 are assembled to the vehicle body as designed, the relative positional relationship between the two measured points 81 and 82 should be the designed positional relationship. For example, if the two measured points 81 and 82 are designed so that the positions in the vehicle vertical direction Z are the same, and the front door 810 and the rear door 820 are assembled according to the design, the two measured points 81 and 82 are aligned in the vertical direction Z of the vehicle (see FIG. 3). However, if either the front door 810 or the rear door 820 is not installed correctly with respect to the vehicle body, the positions of the two measured points 81 and 82 in the vehicle vertical direction Z will be shifted.

Therefore, in inspecting whether or not these doors are installed normally, for example, the relative positional relationship of the two measurement points 81 and 82 in the vertical direction Z of the vehicle is measured. For this measurement, for example, a stepped vernier caliper (see reference numeral 7 in FIG. 1) is used. However, the shapes of the measured points 81 and 82 on the front door 810 and the rear door 820 are not necessarily flat surfaces. In other words, the surface of the stepped caliper or the like against which the measuring instrument 7 is brought into contact is not necessarily a flat surface. Moreover, even if the points to be measured 81 and 82 have flat surfaces, the flat surfaces are not formed continuously over a sufficient area. That is, the measured points 81 and 82 constitute, for example, curved surfaces. Therefore, even a slight deviation in the contact position or posture of the stepped caliper may result in a different measurement value. Therefore, it is not easy to directly bring the measuring instrument 7 into contact with the measured points 81 and 82 to measure the relative positional relationship, and it may be difficult to obtain accurate measured values.

Therefore, by using the measurement auxiliary jig 1 of the present embodiment, the relative positional relationship between the two measured points 81 and 82 can be measured easily and accurately as described above. That is, by arranging the two contact planes 12 and 22 reflecting the relative positional relationship between the two measured points 81 and 82 on the same plane or in parallel, the measuring instrument 7 with respect to the contact planes 12 and 22 Even if the abutment position of is slightly changed, the measured value of the relative positional relationship in the vertical direction Z of the vehicle does not change. Moreover, it is easy to bring the measuring instrument 7 into vertical contact with the contact planes 12 and 22 . As a result, it is possible to easily and accurately measure the relative positional relationship between the two points.

In addition, as shown in FIG. 1, the mutually opposing surfaces of the first jig 10 and the second jig 20 can be used as contact planes 12a and 22a. In this case, for example, in a state where the first jig 10 and the second jig 20 are attached and fixed to the points to be measured 81 and 82, the gap dimension between the contact planes 12a and 22a is set to, for example, the beak of a vernier caliper. By using and measuring, it is possible to easily and accurately measure the relative positional relationship of the measured points 81 and 82 in the longitudinal direction X of the vehicle.

Although not shown, the side surfaces of the first jig 10 and the second jig 20 on the side opposite to the vehicle body 8 (that is, the surfaces on the front side of the paper surface of FIG. 1) can be used as contact planes. In this case, the relative positional relationship of the measured points 81 and 82 in the vehicle width direction Y can be measured easily and accurately.

Moreover, in this embodiment, the mounting and fixing parts 11 and 21 are provided on the lower surfaces of the first jig 10 and the second jig 20, but for example, the first jig 10 and the second jig 20 can also be provided on the side surface of the vehicle body 8 side. For example, at least one of the first jig 10 and the second jig 20 is moved to the points 81 and 82 to be measured by contacting the center pillar of the vehicle body or by fitting it into a hole provided in the center pillar. It can also be attached and fixed to the When forming the mounting fixing portion 11 on the side surface of the first jig 10 or the second jig 20, the mounting fixing portion 11 may also be formed on the lower surface of the first jig 10 or the second jig 20. desirable.

As described above, according to the present embodiment, it is possible to provide a measurement auxiliary jig that enables easy and accurate measurement of the relative positional relationship between two different locations on the vehicle body.
