2. Description of the Related Art Recently, when repairing a vehicle body of an automobile that has been deformed due to a collision accident, for example, Japanese Patent Laid-Open No. 3-19891 is known.
As disclosed in Japanese Unexamined Patent Publication No. 8 (1994), an accident vehicle is drawn into a rectangular horizontal base set on the floor, and the accident car is lifted to a predetermined height by a lifter set in advance on the horizontal base. After supporting the four parts with fixed jacks, the lifter is lowered, and in this state, the appropriate part of the accident vehicle is engaged with the clamp at the tip of the chain extending from the correction tower and towed to pull out the recess and repair the deformation. I am trying. Then, in order to measure whether or not the vehicle body has been restored to its original size, as shown in Japanese Utility Model Laid-Open No. 61-67504, a measuring machine of a size capable of measuring the entire vehicle body is drawn on a horizontal base. I'm measuring.

[0003]

In the above repair, however, a lifter is used to lift an accident vehicle on a horizontal base. However, since the lifter is expensive, the cost of the entire vehicle correction device is high. It is a heavy burden on the user, and it is difficult to handle the measuring instrument because a large measuring instrument is used to measure the repaired condition. There is a problem in that work such as placing and lowering takes time and reduces work efficiency. Therefore, an object of the present invention is to solve all of these problems and to provide a movable measuring machine that is inexpensive and can work efficiently.

Substrate of movable measuring machine configured as described above
As shown in FIG. 4, the horizontal base 2 is removed by removing the supporting legs 27 and 27 while the horizontal base 25 is placed on the horizontal base 25 and moved substantially.
5. Lower the rear end edge of the vehicle 5, pull in the accident vehicle B from the rear side and place it on the horizontal base 25, raise the rear end edge again and attach the supporting legs 27, 27. Next, the substrate 1 of the movable measuring machine is moved to the rear rear surface of the accident vehicle B, and the wheels 3 are locked by stoppers (not shown). Then, a jack (not shown) is placed in the space S on the substrate 1, and the jack is operated to operate as shown by the chain line in FIG.
As described above, the accident vehicle B is lifted up, the fixing bolts 41 are fitted into the through grooves 35, 35, respectively, and moved, and the fixing jacks 34 are supported and supported by the fixing bolts 41.
Each fixing jack 34 is tightened and fixed by the fixing bolt 41.

Then, the accident vehicle B is firmly fixed on the horizontal base 25.

However, in order to repair the front surface of the accident vehicle B, for example, the first mounting rod 29 is fixed as it is or is rotated to a proper position, and if necessary, a correction tower 31.
Is rotated to extend the chain 42 from the correction tower 31, and the clamp 43 at the tip thereof is engaged with the recess or the like to perform a pulling operation. Further, in order to correct the side surface of the accident vehicle B, the first mounting rod 40 is appropriately moved, and the clamp 43 at the tip of the chain 42 extended from the correction tower 31 as shown in FIG.
Is engaged with the concave portion and a pulling operation is performed.

Next, a method of measuring the state in which the deformation is corrected by the movable measuring machine of the present invention will be described. First, the reference point indicating rods 10 and 21 are adjusted to the regular measurement reference positions (for example, a drain hole or a bolt head on the rear surface of the automobile) according to a frame chart determined for each vehicle type of each automobile. For this purpose, the free horizontal rod 7 is moved in accordance with the length measuring scale 5 of the vertical rod 6, the base 11 is further moved in accordance with the length measuring scale 9 on the free horizontal rod 7, and the extension rod 18 is further measured. Expand and contract according to the long scale 24. Then, the heights of the cones 14 and 22 of the reference point display rods 10 and 21 are adjusted according to the height of the accident vehicle B, and in this state, the board 1 of the movable measuring machine is fixed to the rail members 33 and 33 according to the frame chart. Move along. Then, the cones 14 and 22 are connected to the accident vehicle B.
Measure below the measurement reference point of. If the measurement reference position of the accident vehicle B is restored to the original state, the reference point display rods 10 and 21 should be located directly below the measurement reference position. If there is a displacement, the correction work is performed again.

At this time, when the movable measuring instrument is positioned along the longitudinal direction of the accident vehicle B, the marks 26 provided every 1000 mm on the upper surface of the horizontal base 25 are used, and the substrate 1 of the movable measuring instrument is one side moves the substrate 1 so 1000mm per mark 26 units, during which may be measured length by the side length scale Tate杆6,6. That is, by aligning one end of the substrate 1 with the mark 26, measurement can be easily performed at any position, which is extremely convenient.

Further, in the above-mentioned measurement, since the upper surface of the substrate 1 is mirror-finished, the back surface of the accident vehicle can be easily visually recognized from the outside, and the position of the drain hole or the bolt head or the like serving as the reference point is determined. Easy to understand. The above embodiment is a movable measuring machine.
The board 1 is placed on a horizontal base of a vehicle correction device so that it can be moved. In addition to this, a pair of parallel rails is laid on the floor surface, and the base of the movable measuring machine is laid on the top of the rail.
It goes without saying that the plate 1 may be placed and moved, and in this case, for example, the rail is marked every 1000 mm.
