Description

[Detailed description of the invention] [Industrial application field] The present invention is a damage analysis method for measuring the specific degree of deformation and damage to the vehicle frame of a vehicle damaged in a traffic accident. This invention relates to a partial deformation measuring device.

[Conventional technology]

If a car is damaged in an accident such that part of its frame is crushed, the insurance company or auto repair shop will ask you in advance how much it will cost to restore the damaged area before repairs. It is necessary to calculate whether the Conventionally, the amount of deformation at such damaged locations has been measured using a tape measure or tram gauge. In other words, damage to an accident vehicle generally occurs on either the left or right side of the vehicle body, so first, use the punched holes, protrusions, reference holes, etc. provided in the skeleton of the undamaged part that is symmetrical to the damaged part. The distance between two measurement reference points selected from these is measured using a tape measure or tram gauge and recorded. Next, measure between the two measurement reference points at the same position as above in the damaged area,
By subtracting the length of the damaged part from the length of the undamaged part, a numerical value indicating how much the damaged part has been deformed is determined.

[Problems that ideas should solve]

Conventionally, a tape measure or tram gauge is used to measure the amount of deformation of the damaged part as described above, but this method of measuring length with a tape measure or tram gauge makes it difficult to record the length of the undamaged part. Since the length of the damaged part is determined by subtracting the length of the damaged part, there are problems in that the actual deformation length of the damaged part cannot be immediately determined, and the accurate length cannot be determined due to calculation errors. In addition, tape measures have the problem that the scale tends to bend, making them unsuitable for accurately measuring the distance between two measurement reference points, and errors tend to occur.On the other hand, with tram gauges, the scale bar is not retractable, so Although it could be used inside the factory, there was a problem in that the appraiser could not carry it around and use it outside the factory.

[Means to solve the problem]

The present invention solves the above-mentioned problems with the conventional means of measuring the amount of deformation of a damaged part, allows for immediate and accurate reading of the amount of deformation without any calculations, and is convenient for carrying as it can be shortened in length. The purpose is to provide a measuring instrument that is suitable for

In the present invention, as a specific means to achieve such an objective, reference terminals are fixed at right angles to the outer ends of a pipe and a rod that are telescopically inserted, and a reference terminal is fixed at right angles to the outer ends of a pipe and a rod that are telescopically inserted. A scale scale is provided, and a sliding ring of a pointer arm is attached to a part of the rod to be inserted into the pipe, and the pointer arm extends so that the tip of the needle points to the scale scale of the pipe. It is characterized in that it is provided so that it can be fixed and slid.

The reference terminal provided at the outer end of the pipe and rod is a cylinder with a socket for fitting the bolt head at the lower end, and inside this cylinder there is a terminal rod with a pointed lower end attached to the cylinder. It is desirable to have a structure in which the connector can be inserted so that it can be fixed and slid freely.

It is also possible to obtain a sufficient length by connecting a plurality of pipes of different diameters to each other in a plug-in manner and fixing them in the length direction by tightening joints.

[Effect]

In this measuring device, the rod is allowed to move freely relative to the pipe, and the reference terminals at both ends are set on two measurement reference points provided in the skeleton of the undamaged part, which are symmetrical to the damaged part. do. In this state, slide the pointer arm on the rod so that the tip of the needle points to the 0 point on the scale on the pipe, and fix the pointer arm on the rod.

Next, move the pipe and rod onto the damaged skeleton, slide the rod against the pipe, and set the reference terminals at both ends on the two measurement reference points at the same position on the skeleton. Since the pointer arm on the rod is fixed relative to the rod, the tip of the pointer arm moves from the zero point position of the scale graduation of the pipe by the amount that the rod slides, and the position of the scale pointed by the tip of the needle moves from the zero point position of the scale graduation of the pipe. It can be read as the amount of damage and deformation starting from the 0 point.

〔Example〕

Next, an embodiment of the measuring instrument according to this invention will be explained with reference to the drawings. It consists of a reference terminal 3 provided perpendicularly to the outer end.

The pipe 1 is provided with a tightening screw 4 for fixing the rod 2 to the pipe 1, and a scale 5 with a scale 6 centered at the 0 point is attached along the length direction. There is. In addition, the pipe 1 shown in this embodiment has a plurality of pipes 1a and 1b of different thicknesses connected to each other in a plug-in manner, and when the locking joint 7 is loosened, it expands and contracts in the length direction and can be stretched. By tightening the lock joint 7 in this state, it can be fixed integrally in the length direction, and the length can be extended.

Furthermore, the scale 5 of the pipe 1 was attached to the outside of the pipe 1 as shown in FIG. You can.

On the other hand, a pointer arm 8 having a predetermined length for indicating the scale graduation 6 on the pipe 1 is provided parallel to the rod 2. This pointer arm 8 has a proximal end connected to the rod 2.
The scale 5 is fixed to a sliding ring 9 having a tightening screw 10 fitted therein, and the tip 11 at the tip extends so as to point to the lower edge of the scale 6 of the scale 5.

Furthermore, the reference terminal 3 attached to the outside of the pipe 1 and the rod 2 basically only needs to have a pointed lower end, but in this embodiment, the member fixed to the pipe 1 and the rod 2 is A cylindrical body 12 has a socket 13 at its lower end into which a bolt head can be fitted, and a terminal rod 14 having a predetermined length and having a pointed portion 15 at its lower end is inserted into these cylindrical bodies 12. The position of the terminal rod 14 within the cylinder can be adjusted by loosening or tightening a tightening screw 16 provided in the terminal rod 14.

As shown in FIG. 4, when using this measuring device at a location where the left end B1 of the skeleton F is damaged and the right end B2 is not damaged, first loosen the tightening screw 4 of the pipe 1 and 1, the rod 2 is allowed to move freely, and the reference terminals 3, 3 at the outer ends of the pipe 1 and the rod 2 are connected to any two measurement reference points P provided in the undamaged part B2.
1, set on P2. At this time, the measurement reference point P
1, P2 is the hole 17, the tightening screw 16 of the reference terminal 3 is loosened, the terminal rod 14 is pulled out from inside the cylinder, and the pointed portion 15 is set to be inserted into the hole 17. As shown in Figure 5, if the measurement reference point P

After the reference terminals 3, 3 at both ends are properly set between the two reference points P1, P2 in the undamaged part B2 in this way, the tightening screw 4 of the pipe 1 is tightened to fix the rod 2 to the pipe 1. . At that time, tighten the tightening screw 10 on the sliding ring 9 of the pointer arm 8 in the rod 2, slide the pointer arm 8 along the rod 2, and set the needle tip 11 at the tip of the pointer arm 8 at the scale graduation 6 of the pipe 1. After setting it to the 0 point position, tighten the tightening screw 10.
to firmly fix the position of the pointer arm 8 relative to the rod 2.

Next, remove pipe 1 and rod 2 from the undamaged part B2, loosen the tightening screw 4 of pipe 1, and remove rod 2.
After being made movable, it is moved onto the damaged area B1, and the reference terminals 3, 3 at both ends are set on similar measurement reference points P3, P4 in the damaged area B1.
When the rod 2 is slid relative to the pipe 1 in this way, the pointer arm 8 of the rod 2 remains fixed to the rod 2, so the needle tip 11 of the pointer arm 8 changes to the scale according to the amount of movement of the rod 2. The needle tip 11 moves from the 0 point position of the scale 6, and the position of the scale 6 pointed to by the needle tip 11 can be read as the amount of deformation starting from the 0 point. In addition, the measurement between the two measurement reference points was performed between P1 and P2 in FIG. If this is also done, the amount of deformation can be measured more accurately.

〔effect〕

As described above, in the measuring instrument according to the present invention, the pipe and rod are set between two measurement reference points in an undamaged part, and then the pointer arm is set from the tip of the needle to the 0 point on the scale scale. If the pipe and rod are then set between similar measurement reference points in the damaged area, the pointer arm will display the amount of movement from the zero point on the scale scale by the amount by which the rod has slid. Therefore, the amount of deformation can be immediately determined by looking at the scale graduation. Therefore, it is possible to eliminate the troublesomeness and inaccuracy of conventional calculations in which the length between the reference points in the undamaged part is recorded and then the length between the reference points in the damaged part is subtracted. In addition, the measurement work can be done by one person, and by inserting the rod into the pipe, the overall length can be shortened to a length that is convenient for carrying, making it easier to handle than conventional measuring methods of this type. I can do it.
