Abstract

PURPOSE:To take a measurement during repair and to shorten an operation time by arranging a laser gun at a distance from a repair table and moving this laser gun on a perpendicular surface crossing the center line of the table at right angles. CONSTITUTION:The automobile mounting repair table 11 is installed fixedly at a specific position, horizontal rails 1 crossing the lengthwise center line A-A are installed, and vertical materials 2b and 2b are stood on the moving table 2a which moves on the rail 1. Then, an elevation table 3a is provided which moves up and down along the vertical materials 2b and 2b and stop at an optional position, and consequently the vehicle body 16 is mounted and fixed on the table 11 and the laser gun 17 is moved to an optional position to measure the contours of the upper and lower parts of the vehicle body 16; and their deviation quantities from reference values are calculated and the vehicle body is restored and repaired.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a means for measuring the amount of deformation for repairing a vehicle body damaged by a collision or the like.

[Conventional technology] This will be explained with reference to FIGS. 6 to 8.

The floor of the damaged vehicle body 16 placed on the repair stand 11 is fixed to the repair stand 11 by an anchor stand 18, and a reference point is determined by a reference point measuring instrument 19 (for example, a strut gauge), and A chain 15 was stretched between the tower 14, which was attached to the repair table 11, and a proper position on the damaged car body 16, and the deformation of the car body 16 was corrected by pulling the chain 15.

A lateral guide member 30 is provided at the rear end of the repair table 11, and one laser 3 is mounted on the lateral guide member 30 so as to be movable laterally in a range E.
1, a laser gun 17 that can be moved vertically in a range F was mounted on the laser unit 31, and the amount of deformation of the contour of the lower part of the vehicle body was measured by the beam of the laser gun 17.

[Problems to be Solved by the Invention] In order to improve accuracy, the horizontal guide member 30 is installed at a position where it will not be displaced with respect to the repair table 11. Therefore, the laser gun 17 mounted on the horizontal guide member 30 could only measure the contour of the lower surface of the vehicle body 16.

In addition, the base of the upper end of the front wheel strut is often used as a reference point, and in this case, the reference point measuring device 19 is installed on the front side of the vehicle body 16, so the horizontal guide member 30 for the laser gun is placed on the rear side of the vehicle body 16. They were forced to place their positions in the area. As a result, there was a drawback that it was not possible to measure the outline of the vehicle body on the front side, where damage often occurs.

Furthermore, since the laser gun 17 is located below the vehicle body 16, there is a risk that the laser gun 17 may be damaged if an object is accidentally dropped during work.

This invention has been made to eliminate the above-mentioned drawbacks of the prior art.

[Means for solving problems] This will be explained with reference to FIGS. 1 to 6.

The measurement method for repairing a damaged vehicle body according to the present invention is based on a measurement method that moves on a vertical plane B-B that is in front of an automobile repair stand 11 and perpendicular to the longitudinal center line A-A of the repair stand 11. The outline C of the damaged vehicle body 16 is detected by the laser gun 17.
, D.

Further, in the measuring device for repairing a damaged vehicle body according to the present invention, a repair table 11 for mounting on an automobile is fixedly installed at a predetermined position, and the longitudinal center line A-
A horizontal rail 1 perpendicular to A is installed, and a vertical member 2b is mounted on a moving platform 2a that moves on the horizontal rail 1.
2b is erected, and an elevating platform 3a that can move up and down along the vertical members 2b and 2b and stop at any position is provided, and the vehicle body 16 on the repair stand 11 is installed.
A laser gun 17 directed toward is attached to the lifting platform 3a.

[Operation] The vehicle body 16 is placed and fixed on the repair stand 11, and the laser gun 17 is
to an arbitrary position and measure the contour C2D of the vehicle body 16,
The amount of deviation from the standard value is calculated and the vehicle body is restored and repaired.

[Example] 10 is the ground of a repair shop, 11 is a repair stand fixedly placed on the ground 10, and 12 is a repair stand 11 fixedly arranged on the ground 10.
14 is a tower installed on the swivel arm 12, 15 is a chain attached to the tower 14, the tip of which is attached to a suitable position on the vehicle body 16, and is pulled to correct deformation of the vehicle body 16. There is.

In front of the repair table 11, there is a center line A in the longitudinal direction of the repair table 11.
- A horizontal rail 1 is laid in a direction exactly orthogonal to A.

A moving table 2a is placed on the horizontal rail 1, and the moving table 2a is placed on the horizontal rail 1.
A can be stopped at any position. Also, moving platform 2
A vertical member 2b is erected on the vertical member 2b, and an elevating table 3a is attached to the vertical member 2b, and the elevating table 3a can be stopped at any position. A placing plate 3C with a level 3b is provided on the lifting platform 3a, and the placing plate 3C has 3
The top surface of the book can be kept horizontal by adjusting the screw studs 3d. 17 is a laser gun mounted on the mounting plate 3C. The laser gun 17 is swingable (not shown) so that the laser gun 17 can irradiate a beam onto any part of the vehicle body 16 even when the mounting plate 3c is stationary.

If the movable table 2a is moved, the laser gun 17 will be displaced in the horizontal direction, and if the elevator table 3a is raised or lowered, the laser gun 17 will be displaced in the vertical direction. That is, the laser gun 17 is
1 and on a vertical plane B-B perpendicular to the center line A-A of the repair stand, and the vehicle body 16
The contours C and D of can be measured.

[Effects of the Invention] The laser gun 17 is arranged at a position away from the repair table 11, and the laser gun 17 moves on the vertical plane B-B orthogonal to the center line A-A of the repair table 11. It looks like this. For this reason, the entire outline of the vehicle body viewed from the front with respect to the repair area 11, that is, the upper outline C and the lower outline...
...Eliminates the need for setting up the laser gun...
...Measurements can be made accurately, and measurements can be made even during repairs, making a significant contribution to shortening construction time.

Furthermore, since the laser gun 17 is not placed below the vehicle body 16 or in the fog, the laser gun 17 will not be accidentally damaged during construction.
