Thus, the operability is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a measuring machine used for silver-gold repair to restore the body of an automobile that has been deformed due to a collision or the like to its original state.

[Prior Art] When repairing a car body that has been deformed due to a collision, the car body is generally fixed on the ground so that it cannot be moved.
This is done by holding the deformed part with clamps and pulling it with a repair machine, but the applicant has previously developed a measuring machine for measuring whether the body has been repaired to its original dimensions in this type of repair work. The application was filed as No. That is, a central vertical rod is supported horizontally, a horizontal horizontal rod is disposed orthogonal to the central vertical rod, a reference point display is movably disposed on the horizontal vertical rod, and one end of the central vertical rod is disposed so as to be movable. This measuring device is equipped with a laser beam aiming device that can freely rotate in a horizontal plane and a protractor that can measure the angle of rotation.

[Problems to be Solved by the Invention] In the measuring device related to the above-mentioned application, a reference point indicator is placed under a deformed accident vehicle in accordance with a frame chart predetermined for each vehicle type, and the reference point indicator is aligned with the measurement reference position. While the machine is in a crawling position, a cone-shaped magnet with a chain suspended thereon is attached to a reference position on the bottom of the car body, and when the deformed area is towed and corrected, the reference point indicator near the machine is attached. - The restoration state was known by irradiating the laser beam, the Cheno blocking the laser beam, and matching the corresponding reference point display with the Cheno, but this laser was irradiated in a single line. In practice, it is difficult to align and it is difficult to achieve sufficient accuracy for detection, and furthermore, it is unsuitable for detecting positions in the vertical direction or in the horizontal direction. Moreover, this type of laser beam aiming device was only used to accurately detect the correct position of each reference point indicator, and was only used to measure the back side of the car in a flat manner, for example, the width of the car body. There are still problems that need to be improved in terms of functionality and workability, such as inability to apply in the direction or height direction and poor versatility.

Therefore, an object of the present invention is to make it possible to irradiate a cross-shaped laser beam in a cross-shaped manner so as to be movable in the vehicle width direction as well as in the vertical direction, and further to use the cross-shaped laser beam and a reference point indicator in combination to Another object of the present invention is to provide a measuring device which is capable of detecting and measuring not only the vertical direction but also the longitudinal direction of the vehicle, and which can easily determine the center of the laser beam because of the cross beam.

[Structure of the Invention] In order to achieve the above object, the present invention horizontally supports a track vertical rod, arranges a universal horizontal rod perpendicular to the vertical horizontal rod, and places a reference point indicator on the vertical horizontal rod. A track horizontal bar is movably provided on one end side of the track vertical bar, a pedestal is movably disposed on the track lateral bar, and a support is erected on the pedestal. , an elevating pedestal is movably provided on the support, and a cross-shaped laser beam aiming device is attached to the elevating pedestal to irradiate the beam in a cross shape.

[Operation] The irradiation position of the cross-shaped laser beam is set in the vehicle width direction by moving the pedestal installed on the track side beam left and right, and the irradiation position in the vehicle width direction is set by moving the pedestal installed on the track side beam from side to side. The height position can be set by moving the reference point indicator and the cross-shaped laser beam, and the longitudinal position of the car can be set by matching the reference point display with the cross-shaped laser beam, allowing all three-dimensional measurements and detection to be performed. let

[Example] In the figure, 1.1 is two track vertical rods made of square vibrators with length measurement scale 2 displayed by pasting a measuring tape on the surface, which are arranged parallel to each other with a predetermined interval apart. Track vertical rod 1
, 1 are orthogonally disposed on two flexible transverse rods 3, 3 so as to be movable, respectively. A receiving plate 4 is fixed to the lower surface of each of these horizontal horizontal rods 3 near both ends, and two rollers 5 are rotatably supported on the receiving plate 4 so as to sandwich the track vertical rod 1 from both sides. can be freely moved along the track vertical rods 1, 1. A length measurement scale 6 is displayed on the surface of each of the horizontal horizontal rods 3 in the same manner as on the surfaces of the vertical orbital rods 1, 1.

Reference numeral 7 denotes a reference point display body that is vertically expandable and retractable, and a branch-shaped base 8 is movably disposed on the upper surface of the flexible horizontal rod 3, and a round pipe 9 is established on the base 8. A small diameter pipe 10 is loosely fitted therein, and a rod 11 is loosely fitted into the small diameter vibrator 10, and a cone 12 is fixed to the upper end of the rod 11.

In addition, 13 is a thumbscrew for stopping the free movement of the base 8 on the flexible horizontal rod 3, 14 is a thumbscrew provided at the end of the round vibrator 9 to stop the expansion and contraction of the small diameter vibrator 10, and 15 is a thumbscrew for stopping the expansion and contraction of the rod 11. This is a thumbscrew installed at the end of the small diameter pipe 10 to secure it. An extension rod 16 is extendably provided at the tip of each adjustable horizontal rod 3, and a reference point indicator 7' is also provided at the tip of each of these extension rods 16. These reference point display bodies 7' are constructed by attaching a small-diameter pipe 17 to the tip of an extension rod 16 so that it can be adjusted up and down by loosening a thumbscrew 18, and by loosely fitting a rod 19 into the small-diameter vibrator 17 so that it can be expanded and contracted. A cone body 20 is fixed to the upper end of the rod 19, and a thumbscrew 21 provided at the end of the small diameter vibrator 17 is configured to stop the rod 19 from expanding or contracting. Note that a length measurement scale 22 is also displayed on the surface of the extension rod 16.

Further, square pipe-shaped support horizontal rods 23, 23 are fixed to both ends of the track vertical rods 1, 1 to support them. Pulleys 24 are provided at both ends of these horizontal support rods 23, 23, and a screw shaft 25 for the supporting leg is vertically supported, and by operating a handle 26 fixed to the upper end of the screw shaft 25, , the screw shaft 25 moves up and down, and its lower end touches the floor surface, causing each pulley 2
4 is fixed by floating it.

Then, on one end side of the track vertical bars 1, 1, the square pipe-shaped track horizontal bar 27 is moved inwardly from the support horizontal bar 23 via the receiving plate 28 and rollers 29 in the same way as the universal horizontal bar 3. Support freely. As shown in FIG. 3, a cross-sectional rail 3o is laid on the upper surface of the track crossbar 27, and a movable body 31 running along the inside of the rail 30 is mounted. The movable body 31 has two flat plates 31a and 31b fixed vertically at an appropriate interval, and two elliptical concave grooves, the outer sides of which are close to the rail 30, are formed adjacently on the opposing inner surfaces of each plate. A large number of small-diameter balls 32 are loaded between both the grooves, and a portion of the balls 32 protrudes outward at the outer edge. The movable body 31 is caused to travel by rolling of the movable body 32. 33
is a pedestal placed on the movable body 31, and a digital scale display 34 is provided on one side of the pedestal 33 to display the movement position. The digital scale display 34 is a commercially available one, and a length measurement scale 35 is installed in the rail 30 so as to be slightly raised from the bottom surface, and is attached to the body by electrical conduction, so that the distance traveled can be read and digitally displayed. There is. Further, a support 36.36 is erected on the upper surface of the pedestal 33, and the elevating pedestal 37 is arranged on the support 36.36 so as to be movable in the vertical direction, and the position is fixed by tightening the thumbscrew 38.38. That's what I'm doing.

The same digital scale display 39 as described above for displaying the height position is provided on one side of the lift pedestal 37, and a sub-length scale 35 is similarly provided on the support 36 on the side of the digital scale display 39.

Reference numeral 40 denotes a cross-shaped laser beam aiming device installed horizontally on the lifting pedestal 37, and is a well-known commercially available product that emits coherent visible light in a cross shape from the light projection port.

In the measuring device of the present invention configured as described above, first, each reference point display body 7, 7' is aligned with the measurement reference position of the vehicle according to a frame chart determined for each type of vehicle. To do this, the horizontal horizontal rod 3.3 is moved along the track vertical rods 1, 1, the base 8 is moved on the horizontal horizontal rod 3, and the extension rod 16 is extended and retracted. At that time, for example, the position of the reference point indicator 7, 7' and the upper cone 1 are adjusted so that the cross-shaped laser beam aiming device 40 emits light at a predetermined position.
2 and 20, the horizontal direction can be detected by vertical laser beams by moving the pedestal 33 left and right, and the vertical direction can be detected by horizontal laser beams by moving the lifting table 37 up and down. If the tips of the conical bodies 12, 20 at the top of the reference point indicators 7, 7' coincide with the intersection, each reference point indicator 7, 7' has been correctly installed. That is, the device 40 moves the cradle 33 to a predetermined position in the vehicle width direction while looking at the scale on the digital scale display 34, and then moves the lift pedestal 37 up and down while looking at the scale on the digital scale display 39. Then, tighten the thumbscrews 38° and 38 to secure it.

Then, the measuring device is inserted under the floor of the accident car by rolling the pulley 24, and each reference point display body 7° 7' is set at the reference position 1i! of the underfloor surface of the accident car. (Normally, the reference position is the drain hole or bolt head on the underside of the vehicle body.), operate the handle 26 to lower the supporting leg screw shaft 25, and bring the lower end into contact with the floor. This causes the pulley 24 to rise above the floor surface, keeping the measuring machine horizontal and preventing free movement. On the other hand, in the accident car, the reference position of the underfloor surface of the deformed part has shifted, but a conical magnet 42 is magnetically attached to the drain hole at the reference position where the shift has occurred, as shown in FIG. A reen-spherical chino 43 is suspended from the body 42. Then, the deformed part is corrected by gripping the deformed part with the clamp 44 and strongly pulling the tension chain 46 with a well-known pulling tool 45.

At that time, if a cross-shaped laser beam is irradiated from the cross-shaped laser beam aiming device 4o to the reference point indicator 7.7' near the chino 43, the chino 43 will block the laser beam irradiated in the vertical direction, and the chino 43 will also 43 and its corresponding reference point display 7.7' match, corrections can be made in the left and right directions as well as in the front and back directions, thereby making it possible to know the restored state of the accident vehicle A.

In this way, with this measuring device, the laser beam emitted by the cross-shaped laser beam aiming device i40, especially the laser beam irradiated in the vertical direction, can directly measure and detect the distance in the left and right direction, and whether it is returning straight in the horizontal direction can be determined by the horizontal direction. It can be detected by the irradiated laser beam, and if the cross-shaped intersection LC is set as a reference point as shown in Figure 6, the reference position set based on the flame chart can be clearly known by reading the intersection. Therefore, the displacement of the reference point display body 7 can be easily and accurately known.

In addition, with one measuring machine, the cross-shaped laser beam aiming device is 1 ton.
40 can be freely determined in the vehicle width direction as well as in the vertical direction. Therefore, the display body 7.7' is not limited to the one that is used based on the reference point display body 7.7' as in the above embodiment. It is possible to directly read the irradiated laser beam for the upper horizontal and vertical directions of the body where it cannot be used.

That is, in FIG. 7, the cross-shaped laser beam aiming bag [40,
Move the pedestal 33 to the left end and right end of the track horizontal rod 27,
An example of use will be shown in which the laser beam is set to be irradiated from the center line C of the car A to the outer position of the vehicle width (X+O') based on the frame chart, and the position of the deformed part B to be restored is clearly indicated. Further, it goes without saying that the deformation in the vertical direction can also be performed in the same manner.

[Effects of the Invention] As described above, the measuring machine for automobile silver and gold repair of the present invention has a device that emits a cross-shaped laser beam whose center can be clearly seen and is movable in the vehicle width direction and vertical direction. Therefore, it is easy to understand the detection in setting the reference point display and determining all dimensions during repairs.Also, it is possible to measure the front, rear, left, right, top and bottom of the car three-dimensionally and in total while performing the detection, making it an excellent measurement function. This has beneficial effects such as improved performance and workability.
