Abstract

PURPOSE:To enable handy and accurate measurement of the position of a specified part of a frame by a method wherein a reference scale is mounted on a base point as zero position at which a body is hard to deform and a sequential scale is connected thereto. CONSTITUTION:In measurement, an adjustment is made so that a first main staff 16 is at the right angle accurately to first vertical reference rule 1 and horizontal lateral rule 7 and second and third upright staffs 12 and 14 align while the upper ends thereof contact the lower end face of the main staff 16. Then, the heights of the horizontal lateral rules 7, 8 and 9 are read with scales of the vertical reference rules 1, 3 and 5 and moreover, the lateral positions of the upright staffs 10, 12 and 14 are read with scales provided on the horizontal lateral rules 7, 8 and 9. A relative position of a reference point of a frame having the second and third reference rules mounted thereon is determined with respect to the zero point from the measured value obtained to judge a deviation thereof. Then, the tip of a probe rule 18 is set to the reference position of a car to be measured and the position of a probe rule holder 20 is read with a scale of the main staff 16 while the position of the probe rule 18 is with an own scale thereby enabling the determination of a correct frame error.

Since this measuring device is bilaterally symmetric, only one side will be described in the following description.

As shown in FIG. 2, this measuring device is attached to the lower side of the frame of the automobile whose shape is to be measured. In FIGS. 2, 4 and 5, 100
Is an automobile whose frame shape is measured, 102 is an engine, and 104 is a wheel base. The detailed structure of the first vertical scale 1 and the first horizontal scale 7 is shown in FIG.

The main part of the vertical scale 1 is a pair of elongated side plates.
It is a frame composed of 101 and 102 and upper and lower spacers 104 and 105 provided between them. Flat side plate 10
1 and 102 are each equipped with a scale 103,
Further, between the side plates 101, 102 is inserted a cylindrical body 107 having a square cross section, which slidably inserts the first horizontal horizontal strip 7, and the side surface of the cylindrical body 107 extends along the flat plate 101. A pair of guides 108 and 109 for moving the guide 107 are provided, and the guide 109 has a set screw for fixing the tubular body 107.
110 are provided. Therefore, the first vertical scale 1
The first horizontal horizontal strip 7 and the first horizontal horizontal strip 7 are slidable in the longitudinal direction thereof, and can be fixed at any position by tightening the fastening screw 110, and their positions can be fixed by a scale provided on those members at any time. Can be read.
Although the structure of the first vertical scale 1 and the first horizontal horizontal scale 7 is shown in FIG. 3, other components such as the first upright side scale 10 are shown.
The configuration and the relative relationship with the vertical scale 1 are the same.

Further, a screw 106 for attaching to the frame of the automobile is provided on the upper end of the spacer 105,
By means of this screw 106, the first vertical scale 1 is mounted at right angles to the zero position reference plane of the frame of the motor vehicle to be measured.

This zero position is usually provided in a place where it is relatively unlikely to be damaged even when the frame of an automobile is deformed due to a traffic accident or the like, and when repairing the deformed frame, this zero position serves as a reference.
In this measuring apparatus, first, the first vertical scales 1 and 2 are attached to the zero position.

Next, a first horizontal horizontal scale 7 is attached through the vertical scales 1 and 2. In the same manner, the second vertical scales 3 and 4 are attached to the reference points provided in the vicinity of the front suspension of the automobile, and the second horizontal scale 8 penetrates them. A third vertical reference scale 5 and 6 is attached to the front end portion of the frame, and a third horizontal horizontal scale 9 is attached so as to extend therethrough.

Next, first upright side scales 10 and 11 are attached to both ends of the first horizontal horizontal scale 7, and second upright side scales are attached to both ends of the second horizontal horizontal scale 8, respectively. 12 and 13 are attached, and third upright side scales 14 and 15 are attached to both ends of the third horizontal horizontal scale 9, respectively.

At the top of this first upright side scale 10 and 11,
A pair of left and right main measuring scales 16 and 17 are attached so as to be rotatable in two axial directions. The connecting portion between the first upright lateral scale 10 and the main measuring scale 16 comprises a hinge 22, a pin 23, and a shaft 23. Therefore, the main measuring scale 16 can be tilted up and down by the hinges 22 and can also be horizontally rotated about the shaft 23.

The lever 24 is fixed to the plate on the movable side of the hinge 22, and its tip is connected to the pointer of the indicator 25. When the main measuring scale 16 rotates around the shaft 23,
The lever 24 is adapted to rotate the pointer of the indicator 25. The first main measure 16 is exactly the first horizontal horizontal measure 7
In the position at right angles to, the pointer of this indicator 25 indicates zero.

In the measurement, first, the first main measuring scale 16 becomes a right angle to the first vertical reference scale 1 and the horizontal horizontal scale 7 accurately, and the second and third upright side scales. 12 and 14 are correctly positioned directly below the first main measuring scale 16 and the first to third upright lateral scales
Adjust so that 10, 12, and 14 are aligned, and the upper end face of the main measure 16 is in perfect contact with the lower end face.

After making such adjustments, the heights of the horizontal horizontal scales 7, 8 and 9 are read on the scales of the vertical reference scales 1, 3 and 5 and further the heights of the upright side scales 10, 12 and 14 are read. The lateral position is read on the scale provided on each horizontal horizontal strip 7, 8 and 9. From these measured values, the relative position of the reference point of the frame to which the second and third scales are attached to the zero position is determined, and the deviation thereof is found.

Next, as shown in FIGS. 4 and 5, the tip of the search ruler 18 is aligned with the reference position described in the data sheet published for each vehicle type of the vehicle to be measured. Therefore, the main measuring scale 16 is rotated up and down to adjust the position of the search scale holder 20 on the main measuring scale 16, and its longitudinal position is adjusted so that the tip of the search scale 18 comes into contact with the reference position to be measured. The position of the search ruler holder 20 is read on the scale on the main measuring scale 16, and the position of the search ruler 18 is read on the scale provided on itself. The actual size corresponding to the reference size described in the data sheet is calculated from the read value of the scale of each constituent member thus obtained, and the error of the frame is obtained.

In addition to the apparatus according to the present invention, a measuring scale 27 for engine check attached to the strut towers 26 and 27 of the engine as shown in FIG. 2 is attached.

Since the present invention is constructed as described above, according to the present invention, it is not necessary to provide any stand or other fixed equipment on the ground, and the zero position provided for the automobile frame situation to be inspected is not required. The dimensions of each part described in the data sheet can be accurately measured based on the standard.
