Abstract

PURPOSE:To achieve accurate measurement of a vehicle body in a simple and clear manner for a very short time as compared with the conventionalvehicle body measuring machine by providing retainable hungers at three and more reference points properly separated off any straight line on the body. CONSTITUTION:A vehicle body measuring machine has three retainable cord- shaped hungers 4 properly the same in the length with a T-shaped fixture 2 at the upper end thereof and a magnet 3 at the lower end thereof at reference points. In addition, a longitudinal been 6 is arranged to be crossable across three reference points properly separated on a body 5 while four transverse beams 7 with a proper length horizontally are arranged to slide along the longitudinal beam 6 maintaining the right angle with respect thereto 6. This eliminates troublesome positioning work taking greater part of working time for measuring the body thereby enabling the completion of accurate measurement of the body for a far shorter time than before in a simple and clear manner.

Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a vehicle body (hereinafter referred to as a "vehicle body").
is used in a broad sense, including outer panels, frames, reference points, etc. This invention relates to a vehicle body measurement device that does not require positioning work and is used to measure the vehicle body by hanging it on the vehicle body when modifying the vehicle.

When a car body is damaged due to an accident, repairs are carried out by pulling or pushing the damaged part of the car body with great force.

At that time, the reference point whose position has shifted due to damage (
In this specification, the term "reference point" refers to a point that is described as a reference point in a commercially available dimensional drawing of a vehicle body or a location that can serve as a reference point for dimensions when measuring a vehicle body. In addition,
Among these reference points, those located at normal positions are called normal reference points, and those that have deviated from their normal positions due to accidents or the like are called abnormal reference points. ) by returning it to its original normal position while measuring it with a vehicle body measurement device.
Repairing the car body to its original condition is commonly carried out by auto body maintenance companies.

The main types of conventional vehicle body measuring machines include (1) centering gauges, (2) vehicle body measuring machines that perform positioning work using vertical gauges, and [ro] vehicle body measuring machines that perform positioning work using laser beams. There are measuring machines, etc. Each of these will be explained below [1] Centering gauge 1 Configuration example Vehicle body latches that can be latched to reference points located at symmetrical positions are provided extending upward from both ends of a telescoping horizontal gauge, In the center of the horizontal gauge is a needle that stands up to indicate a point on the center line of the vehicle. A centering gauge with this configuration has 4 to 8 points in 1 set.

2 Usage Example Based on the body dimension drawing of the vehicle whose body center line has been bent or twisted due to damage due to an accident, etc., select 4 to 8 sets of appropriate reference points that should be in symmetrical positions, and Set the length of each side gauge and vehicle body hook according to the position of the reference point, and hang 4 to 8 centering gauges by hooking them to the reference point of each set.

When viewed from directly in front of the vehicle body, the needles of these horizontal gauges are deviated or tilted vertically and horizontally, so that the bending or twisting of the vehicle center line is determined based on this. Therefore, we carried out repair work on the car body until these needles appeared to overlap into one.

It is determined whether the vehicle body is in a normal state by measuring the position of the vehicle body and determining whether the vehicle body is in a normal position. On the other hand, the centering gauge is only used to check the bending and twisting of the center line of the car body, and cannot measure the position of each reference point.
It has almost no function as a vehicle body measurement device. For example, in the case of an accident vehicle that requires measurement, the reference points that should be located symmetrically are often located in the front and rear, left and right directions, or a combination of these directions, but even if such a vehicle body is measured with a centering gauge, , it is not possible to determine in which direction and by how many degrees the reference point is located. For this reason, the centering gauge cannot be used as an indicator for car body repair work, and can hardly be used as a car body measurement device.Therefore, although it is inconvenient, it can be used in practice from a completely different perspective than the centering gauge. The vehicle body measuring machines shown in [2] and [6] below were devised based on this.

[2] Vehicle body measurement device 1 that performs positioning work using a vertical gauge Configuration example: It has ground contact feet at the four corners of the left front, right front, left rear, and right rear corners, and uses the ground contact feet to touch the ground or a vehicle body repair table, etc. (hereinafter referred to as There is an installation stand that is installed on the ground (simply referred to as the ground), and it can be moved forward, backward, left and right on the installation stand, and there are four vertical gauges that can be expanded and contracted up and down like a radio antenna, and a display. There are about 6 vertical gauges, and each vertical gauge has a contact part on its top end to make contact with the normal reference point, and each indicator has a reference point display part on its top end to show the normal position of the abnormal reference point. be.

In addition, each grounding foot is configured to be able to expand and contract up and down with a screw by turning a handle. Note that this vehicle body measurement device has a size close to the vehicle body in the front, rear, left and right directions. There are also ground-contacting feet that use cylinders to expand and contract with air pressure.

2 Usage example: Lift the car body, place it on a stand fixed to the ground for car body repair work, fix it, and bring the car body measurement device to the side of the car body.

Then, each component is set in a required arrangement in the vehicle body measuring device, and the vehicle body measuring device is appropriately installed under the vehicle body (this task is simply referred to as placement task in this specification). The content is to select four appropriate normal reference points and one abnormal reference point on the vehicle body, and select the four normal reference points and one abnormal reference point written on the plan view of the vehicle body dimension drawing. Same as the normal position arrangement of
Four vertical gauges and one display are appropriately moved back and forth and left and right to accurately arrange them on an installation stand. Then, by expanding and contracting the vertical gauge and the display body,
From the car body reference line written on the side view of the car body dimension drawing,
Accurately adjust the lengths of the four vertical gauges and the one indicator to the heights of the normal reference point of the location and the abnormal reference point of one location. The vehicle body measurement device in this state is inserted into the underside of the vehicle body and placed on the ground under the vehicle body via the ground foot. The placement work is finished here.Next, there is work to accurately position the display for indicating the normal position of the abnormal reference point at the normal position of the abnormal reference point (in this specification, this work is simply referred to as positioning work). I do. First, the contents are as follows:
Hold the vehicle body measurement device in your hand and move it back and forth and left and right so that each contact point at the top of the vertical gauge is located approximately directly below the normal reference point. Then, with the goal of bringing each of the four contact parts into accurate contact with the four normal reference points, gradually extend the left front, right front, left rear, and right rear grounding feet to lower the installation base. Lift up until each contact part reaches the height just before it touches each normal reference point, then stop the lifting operation and place the four contact parts exactly below the four normal reference points. While carefully checking the positions of the four normal reference points and the four contact points, hold the vehicle body measurement device in your hand and carefully move it back and forth and left and right to align them, and then align the four contact points. Gradually extend each of the four contact parts and lift the vehicle body measurement device to a height and angle at which the four contact parts accurately contact the four normal reference points. At this point, the reference point display section is located at the normal position of the abnormal reference point, and the positioning work of the reference point display section is completed.

Next, measurement work and car body modification work will be carried out. The content is that by looking at the deviation of the position of the abnormal reference point with respect to the reference point display section, the deviation of the position of the abnormal reference point can be measured. Thereafter, the vehicle body modification work is performed until the abnormal reference point accurately contacts the reference point display section, and by observing that the abnormal reference point has made contact, it can be determined that the abnormal reference point has returned to its normal position.

6. Disadvantage (b) As mentioned above, the positioning work consists of many troublesome tasks, and this alone is very troublesome. Moreover, the actual positioning work cannot be performed smoothly as described above, and takes a very long time. The reasons are listed below.

When lifting the vehicle body measurement device by extending its 14 ground-contacting legs, I walked around the four handles located near the four corners of the bottom of the vehicle many times in order and adjusted each one. There must be.

Part 2: The reference point is often located in a narrow place behind the floor of the car body or deep inside the frame, etc., where it is hidden by parts, so in order to make the contact part accurately contact the normal reference point, the reference point When visually inspecting the vehicle, you must squat down and stick your head in a position where you can clearly see the reference point within 50 cm of the reference point on the underside of the vehicle, and carefully observe the condition. No. and 4
Such work is required for each normal reference point of the location.

Part 6: In addition to the work shown in Part 2, in order to accurately contact the contact part with the normal reference point, stick your head out from under the car body, hold the car body measurement device in your hand, and place it in a place where you can move it forward, backward, left, and right, and at each handlebar. You must walk to the location and adjust the position and angle of the vehicle body measurement device appropriately. Then, stick your head into the above position again and check whether the deviation between the normal reference point and the position of the contact part has completely disappeared, or how it has changed, and if it is still deviated, This process must be repeated several times.

Part 4: As mentioned above, it is not possible to see all four normal reference points at once, so the work to accurately bring the contact points into contact must be done for each normal reference point. Therefore, if you move the body measuring device back and forth or left or right in an attempt to bring the contact part into precise contact with one normal reference point, or if you extend your ground contact foot with the steering wheel, the G will not accurately contact the normal reference point. Other contact parts that have been left in place may also shift their positions due to movement UA, or the vertical gauge may bend. Then, the contact part G becomes difficult and the work to make accurate contact has to be done again. In other words, the work is not finished just by making one turn while making contact with the four normal reference points (Katsul/) in order, but as you repeat this several times, you will gradually come into contact with all four points accurately. The reality is that it will become.

Part 5: All of the above operations must be performed with great care and accuracy down to the millimeter. This is because this positioning work is troublesome.If done carelessly, for example, the reference, cutting force (force) etc. may be measured while being positioned at a position 3 mm off from the normal position. If you do this, the corrected part of the car body will end up being off by 3 mm, so precision in the mm range is necessary for safe driving and for the accurate mounting of parts such as doors and bonnets. This is because it becomes useless as a vehicle body measurement device for vehicle body modification work.

(c) Car body repair work often involves repeatedly pushing and pulling the car body with a force of 6 to 10 tons or more. However, in reality, it is unavoidable that the vehicle body moves by several millimeters to several tens of millimeters during vehicle body modification. In that case, while the car body moves, the car body measuring machine remains in the same position, so even if you perform the positioning work carefully as described above, the car body will shift from the car body measuring machine during car body repair work. I end up. Therefore, if the car body is measured directly, errors will occur, so the troublesome positioning work often has to be redone many times during car body repair work.O [6] Positioning work using laser beams Vehicle body measurement device 1 Configuration example There is a vertical gauge that is slightly longer than the overall length of the vehicle body and extends in the front-rear direction, and a horizontal gauge that is slightly longer than the overall width of the vehicle body and extends in the left-right direction.The front end of the vertical gauge and the left end of the horizontal gauge are inset. Together, both gauges form an L shape. There are grounding feet extending downward at the rear and front ends of the vertical gauge and the right end of the horizontal gauge, and by adjusting the length of each grounding foot with a screw, the height and longitudinal inclination angle of each gauge can be adjusted. These grounding feet allow both gauges to be placed on the ground. At the rear end of the vertical gauge is a laser beam oscillator that emits a laser beam parallel to the longitudinal direction of the vertical gauge, and each gauge has a reflector that is movable on the gauge and reflects the laser beam in an approximately horizontal orthogonal direction. There is one mirror each. Each reflector has legs that can be adjusted in length with screws, allowing the laser beam to be reflected up or down at right angles. On the other hand, there is a hanging scale that has a transparent plate-like scale with a hanging tool at the upper end that can be hung on a reference point, and a part corresponding to the reference point that can slide up and down along the scale. (The length of the hanging scale refers to the distance from the hanging tool to the part corresponding to the reference point.) 2 Example of use When lifting a car body and fixing it to the ground, Place the vehicle on a stand and secure it, then bring the body measurement device to the side of the vehicle.

First, do the placement work. The contents include two appropriate sets (i.e., four locations) of normal reference points located symmetrically on the vehicle body and one abnormal reference point (in this case, the abnormal reference point is located ahead of the normal reference point). ), and match the length of each hanging scale to the distance from each of the five reference points to the car body reference line written on the side view of the car body dimension drawing, and set the five hanging scales. Hang the scale at the reference point. On the other hand, mark the six points on the vertical gauge at the same distance in the longitudinal direction between the normal positions of the five reference points shown on the plan view of the car body dimension drawing, and mark them slightly below the left side of the car body. Both gauges are placed on the ground in an appropriate L-shape using six ground contact feet so that the vertical gauge is located at the front side of the vehicle body and the horizontal gauge is located slightly below the front side of the vehicle body. The placement work ends here.

Next, the work of accurately positioning the display to indicate the position corresponding to the normal position of the abnormal reference point (referring to the position where the present invention is located) at the position corresponding to the normal position of the abnormal reference point (this work also This is simply referred to as positioning work in this specification because it has the same purpose as positioning work. The contents will be explained step by step below. Position the reflector accurately at the last mark on the vertical gauge and irradiate the laser beam. Then, vertically move the laser beam until it accurately passes through the parts corresponding to the two reference points of the two hanging scales suspended from the rear group of the normal reference points located symmetrically. Adjustments are made by holding the gauge in your hand and moving it back and forth and left and right, by expanding and contracting the grounding feet at the ntJ end and rear end of the vertical gauge, and by expanding and contracting the legs of the reflector of the vertical gauge.

Furthermore, move the reflector to the second mark from the rear and irradiate the laser beam to measure the position and angle of the rearmost mark on the vertical gauge relative to the two rear reference points that were aligned in the front. While being careful not to shift, move the front and rear ends of the vertical gauge until the laser beam accurately penetrates the part corresponding to the reference point of the two hanging scales suspended from the front set of the normal reference points. Adjust by expanding and contracting the grounding foot at the end. After fixing the vertical gauge at this position and angle, move the reflector of the vertical gauge to the front end of the vertical gauge so that the reflected laser beam is at an angle that illuminates a predetermined location on the reflector of the horizontal gauge. Hold the right end of the horizontal gauge in your hand and move it back and forth, and also extend and contract the grounding foot to match. As a result, the horizontal gauge becomes perpendicular to the vertical gauge. After the horizontal gauge is fixed at this position and angle Adjust by moving the reflector of the horizontal gauge to the left or right, or by extending or contracting the legs of the reflector, until the area corresponding to the reference point of the hanging scale is illuminated accurately. On the lateral gauge located away from the position of the reflector by the same distance in the left-right direction from the appropriate one normal reference point described on the plan view of the vehicle body dimension drawing to the normal position of the abnormal reference point. Mark the position of .Then, place the reflector exactly at the mark and place the laser beam when irradiated, and the reflector of the vertical gauge exactly at the mark near the front on the vertical gauge. The intersection point with the laser beam when positioned at and irradiated will indicate the position equivalent to the normal position of the abnormal reference point.The positioning work ends here.

Next, measurement work and car body modification work will be carried out. The content is determined by observing the positional deviation between the laser beam reflected by the reflector at a predetermined position on the vertical gauge and the reference point equivalent part of the hanging scale suspended at the abnormal reference point. It is also possible to measure the rotation of the position up and down. Similarly, by looking at the positional deviation between the laser beam reflected and irradiated by the reflector at a predetermined position on the horizontal gauge and the part corresponding to the reference point of the hanging scale suspended from the abnormal reference point, the abnormal reference point can be detected. It is possible to measure the rotation of the position from side to side and up and down. After that, the car body is repaired until the part of the hanging scale that corresponds to the reference point suspended from the abnormal reference point is located at the intersection of the laser beams, and by checking that it is located at the intersection, the abnormal reference point is located at the normal position. It is possible to measure the return to .

6゛Disadvantage (d) As mentioned above, the positioning work consists of many troublesome works, so it alone is very troublesome. Moreover, the actual positioning work cannot be performed smoothly as described above, and takes a very long time. The reasons are listed below.

Some 1 Hanging from the rear group of the normal reference points 2
In order for the laser beam to accurately penetrate the parts corresponding to the two reference points of the book hanging scale, it is necessary to move the vertical gauge as described above back and forth and left and right, extend and retract the two grounding feet, and reflector. It is not enough to simply extend and retract each leg once; instead, each of these tasks must be repeated several times. This is because each of these tasks mutually influences the results of the other tasks.

Part 2: When performing work to ensure that the laser beam accurately penetrates the parts corresponding to the two reference points of the two hanging scales suspended from the front group of the normal reference points, at that time, in Part 1 above, Since the position and angle of the most rearward mark on the vertical gauge with respect to the parts corresponding to the two rearward reference points that have been combined are shifted, it is necessary to redo the step 1 above.

Furthermore, when I redid the work in Part 1 above, the position and angle of the second mark from the end of the vertical gauge were shifted relative to the two front reference points, so I had to repeat these steps. You have to repeat it over and over again.

Part 6: The above work requires walking back and forth between the six feet on the ground and between them and each reflector.

Part 4: All of the above operations must be performed with great care and accuracy down to the millimeter. This is because even though this positioning work is troublesome, if it is done carelessly, for example, the intersection of the laser beam reflected by the reflector positioned at a predetermined position will be three degrees from the position equivalent to the normal position of the abnormal reference point. If you measure with the position shifted by 3 mm, the corrected part of the car body will be 3 mm as it is.
Vehicle body measurement equipment for vehicle body repair work that requires accuracy in units of I+Im for safe driving of the vehicle and for accurate standing of parts such as doors, bonnets, and parts. This is because it becomes useless.

(e) Same as the drawback of (C) above.

As explained above, this type of vehicle body measurement device accurately displays the normal position of the abnormal reference point or the equivalent position of the normal position, and displays the abnormal reference point or the reference point of the abnormal reference point. Measurement is performed by looking at the positional deviation from the corresponding part. With this type of conventional vehicle body measuring machine, six operations, including placement, positioning, and measurement, are required to complete the measurement of the vehicle body. Among them, the arrangement work is a work of setting each component of the vehicle body measuring device in the required arrangement based on the vehicle body dimensional drawing, so it can be easily performed in a short time. In addition, measurement work is only a visual check, so it is very time-consuming.
It can be done in an instant. On the other hand, positioning work requires careful handling of a body measuring device that is close to or even larger than the vehicle body in the front, rear, left, and right directions, and is carried out in three dimensions: length, width, and height. Although the work involves positioning with millimeter accuracy, it is extremely troublesome, takes a long time, and is difficult. Therefore, most of the work time required to complete the measurement of the vehicle body is spent on this positioning work. Moreover, with this type of conventional body measuring machine, the body of the vehicle would shift many times during body repair work, so
This method also has the disadvantage that once the positioning work has been completed, it is often necessary to redo it over and over again. As a result of the above-mentioned drawbacks, conventional vehicle body measuring machines of this type tend to give inaccurate measurements and take a long time to complete measurements, making them difficult to use. not being used.

Therefore, in the automobile body maintenance industry, etc., it is necessary to develop car body measuring machines that can easily and quickly perform the positioning work that takes a long time to complete car body measurements. We are requesting a vehicle body measurement device that does not require repositioning work during repair work. In response to this, the automotive tool and measuring instrument manufacturing industry has been working hard to develop such vehicle body measuring instruments for many years in order to meet these demands. I can't develop it.

The purpose of the present invention is to meet the needs of the automobile body maintenance industry, etc.
In addition, it is a car body measuring machine that is one step more advanced than the car body measuring machine that is the goal of development efforts in the automotive tool and #shaft manufacturing industry, in other words, it does not require any positioning work at all, and moreover, it can perform positioning work during car body repair work. By completely eliminating the trouble of redoing the steps, even inexperienced people can easily and accurately measure the vehicle body, and the measurement can be completed in an extremely short time compared to conventional vehicle body measuring machines of this type. Our goal is to provide a cutting-edge vehicle body measurement device.

Embodiments of the first invention will be described below with reference to FIGS. 1 and 2. Note that Figure 1 is a side view showing the vehicle body measuring device of this embodiment suspended from the vehicle body, and Figure 2 is a perspective view showing only the vehicle body measuring device, normal reference point, and abnormal reference point. It is a diagram. In addition, the reference points selected in this example have a 7-shaped metal fitting (2) at the upper end that can be latched to the reference points whose normal heights are the same, and a magnet (3). has six string-like hanging bodies (4) of the same length at the lower end, making it possible to hang between six reference points that are appropriately spaced apart and not on a straight line on the vehicle body (5). Vertical bars (6) and vertical bars (6) with appropriate lengths in the front and rear.
It consists of four horizontal bars (7) of appropriate length on the left and right sides that slide along the vertical bars (6) while maintaining a right angle to the vehicle body (5). A frame (8) is constructed. Moreover, it has the same length as the hanging body (4), and
The lower end of the conical display body 00) whose upper end serves as a reference point display section (9) for displaying the normal position of the abnormal reference point (1) is a magnet (n), and this is attached to the frame ( 8), and attach the reference point display section (9) to the hanging body (4).

This usage will be explained next.

First, do the placement work. The content is to select 6 normal reference points (1) and 1 abnormal reference point (1') that are not on a straight line and are appropriately spaced apart from each other on the vehicle body (5), and select each of the horizontal rails (7

Each hanging body (4) is locked to the body, and the vehicle body measurement device is suspended from the underside of the vehicle body (5) as shown in FIG. The placement work ends here.

At this point, the positioning is done naturally without any positioning work, and the reference point display section (9) is accurately located at the normal position of the abnormal reference point (1').Next, measurement work and car body repair work are performed. I do. The contents are shown in the reference point display area (9
), the deviation of the position of the abnormal reference point (1') is measured by observing the deviation of the position of the abnormal reference point (11) with respect to the position of the abnormal reference point (1').

After that, repair the vehicle body until the abnormal reference point (1.) accurately contacts the reference point display section (9), and check that the abnormal reference point (1.) is in the normal position. It is measured that the temperature has returned to .

Next, an embodiment of the second invention will be described with reference to FIG.

It has six string-like hanging bodies (4) of appropriate lengths, each having a magnet (0) at the upper end that can be attracted and locked to a reference point, and a magnet (b) at the lower end. A frame (8) that can be suspended from a rectangular plate-shaped car body with appropriate lengths in the front and rear and left and right sides, and can be hung between three reference points that are appropriately spaced and not on a straight line on the car body. Configure. The frame (8) has a scale (not shown) with many vertical and horizontal lines that intersect at right angles.

Fix the laser oscillator (b)) to the left rear end of the frame (8) at an angle that will irradiate the laser beam (g) parallel to the top surface directly in front of you, and attach the vertical rail 06) and the horizontal rail α.
η is provided with one reflective mirror (0υ) that is movable along each rail and that reflects the laser beam in a perpendicular direction parallel to the top surface of the frame (8), A laser irradiation mechanism consisting of these laser oscillators ((2) and reflectors (A), Ql) is configured to be suspended from the vehicle body via a hanging body (4) and a frame (8). On the other hand, a string-like hanger (c) with a 1-shaped metal fitting that can be locked to the reference point is installed at the upper end, and the ring at the reference point is fixed in relation to the position of the laser beam (e). A transparent plate (c) that connects the dot-like reference point portion to be displayed (c) to the hanging tool (c)
An indicator body Gl! which can be hung on the vehicle body consisting of these hanging tools (c) and a reference point equivalent part (goods). Consists of one line of time.

This usage will be explained next.

Lift the car body and place it on a stand fixed to the ground for car body repair work.

First, do the placement work. The contents are 6 normal reference points (1) and 1 at appropriately distant locations on the vehicle body that are not on a straight line.
Select the abnormal reference point (11) at the location, and mark it appropriately at four locations on the vertical rail (16) at the same distance in the longitudinal direction between the normal positions of the reference point written on the plan view of the vehicle body dimension drawing. , and similarly mark the four dark spots of the horizontal rail θη at the same intervals as the horizontal intervals between the normal positions of the reference points. The magnet (15) at the lower end of each hanging body (4) is attracted onto this (8). In addition, Gl! is placed on each reflector at the position of the mark made to indicate the normal position of the abnormal reference point (C). Position υ. Match the distance from the upper end of the indicator body (C) to the reference point equivalent part G24 with the distance from the normal position of the abnormal reference point (11) described in the side view of the vehicle body dimension drawing to the vehicle body reference line, The indicator body) is suspended from the abnormality reference point (1.). Also, the length of each hanging body (4) should be made to match the distance from each normal reference point (1) to the vehicle body reference line plus the distance from the top surface of the frame (8) to the laser beam (E) axis. Each of the hanging bodies (4) is locked to each normal reference point (1), and the vehicle body measurement device is suspended from the underside of the vehicle body.The arrangement work is completed here.

At this point, without any positioning work, the laser beam (e) reflected by the reflector (a) of this vertical rail (16)
and the laser beam (not shown) reflected by the reflector ψυ of the horizontal rail (17) when the reflector ψυ of the horizontal rail (17) is located at the front end of the vertical rail 06), and the abnormal reference point (1') Displays the equivalent position of the normal position.

Next, measurement work and car body modification work will be carried out. The contents are the laser beam (to) that is reflected by the reflector at a predetermined position on the vertical rail 06) and the part corresponding to the reference point (to) that is irradiated to the indicator suspended at the abnormal reference point (1). By looking at the positional deviation from (c), it is possible to measure the deviation in the position forward and backward and up and down of the abnormal reference point (1'). Similarly, the reflector Ql at a predetermined position on the horizontal rail α'7)
) and the abnormal reference point (1

1") can be measured to the left and right and up and down. After that, the index object e suspended from the abnormality reference point (1') can be measured.
Car body repair work is carried out until the reference point corresponding part 04 of Y is located at the intersection of the laser beams, and by checking that it is located at the intersection, it is determined that the abnormal reference point (one has returned to the normal position). can.

In the prior art examples and embodiments of the invention, in order to simplify the explanation, the case where one abnormality reference point is measured is explained, but in actual vehicle body measurement work, usually 4 to 7 abnormality reference points are measured.
It is often necessary to measure anomalous reference points at a certain level. In that case, the number of display bodies, transparent hanging scales, or indicator bodies may be increased accordingly. Further, the lengths of vertical gauges, transparent hanging scales, hanging bodies, etc. may be adjusted without using the vehicle body reference line as a reference.

Some car body repair shops only handle specific car models, and in those cases, frames, hanging bodies, display bodies, and indicator bodies are constructed and manufactured in advance in a certain positional relationship and length according to that car model. However, it may be used as is, and therefore, the positional relationship and length of the frame, hanging body, display body, and indicator body may be configured so as not to be adjustable.

In this specification, "locking to a reference point" includes locking to a vehicle body using the reference point as a reference. for example,
As shown in Figures 4a and 4b, it consists of a hanging body (4) or hanging tool (with a magnet whose upper part is branched) and a vertically long needle (c) in its center. Then, this needle (goods)
) may be attracted and locked by a magnet so that it points to a reference point. In this case, the distance between the tip of the branch-like magnet and the tip of the needle may be quite long.

In this specification, a "suspended body that can be locked to a reference point" refers to a suspended body that can be connected to a reference point to such an extent that the suspended body as a whole can withstand the load G of the vehicle body measurement device and suspend the vehicle body measurement device. Refers to the body. Therefore, for example, even if a part of the hanging body is in contact with a reference point, it is sufficient that the whole hanging body can suspend the vehicle body measurement device.

It goes without saying that the configurations of the embodiments of the first invention and the embodiments of the second invention may be applied to each other as appropriate.

In the embodiments described above, a crosspiece-shaped or plate-shaped frame is provided, but the present invention is not limited to these. In other words, the frame is
Any shape, structure, or combination may be used as long as it can connect the hanging bodies and the display body or laser irradiation mechanism.

It is also possible to provide a frame having hanging bodies that can be latched to four or more reference points that are appropriately spaced apart and not on a straight line on the vehicle body. Also,
The frame may lose its balance depending on the placement of the suspended body and the position of the center of gravity of the frame, so in such cases, it is possible to stabilize the frame by placing weights at appropriate positions on the frame. .

The frame may be made of aluminum, plastic resin, etc. to make it lightweight. In such cases, the frame and the hanging body can be connected by using adhesive tape on the lower part of the hanging body, or by drilling a number of screw holes on the frame and fixing the lower part of the hanging body with screws. They may be connected together, or they may be connected by providing a frame having a number of hangers and hooking the hanger at the lower end of the hanging body onto an appropriate hanger. Further, the suspension body and the frame body may be fitted together and connected to the frame body, or the hanging body and the frame body may be formed integrally.

The frame may have a structure of two or more stages. In addition, when displaying a right angle on the frame, it is sufficient if the number is displayed to the extent that the right angle between the front and back direction and the left and right direction can be recognized. There is an advantage that lifting machines of frames without right angle markings are less likely to be damaged by shaking, but even if they are made into rod-shaped or plate-shaped structures, or structures in which the hanging bodies remain perpendicular to the frames, good.

A reference point display section (9) may be provided on an inverted character-shaped display body 00) as shown in FIG. In this case, it is convenient to measure a reference point located at the top of the vehicle body.

In addition to the above-mentioned configurations for attaching the display to the frame, there are adhesive tapes, weights, screws, bolts, nuts, fittings, and the like. Further, the display body and the frame may be formed integrally.

The indicator body in the embodiment of the second invention does not need to have a transparent part, and another laser oscillator may be provided for the reflecting mirror of the side rail. Further, the reflecting mirror may be replaced with a laser oscillator.

Examples of configurations that allow the length of the index body to be adjusted include the following.

■ A part of the index body is tied or rolled up, or a length adjustment clip is used. ■ A part of the index body is overlapped, and the length can be adjusted depending on the amount of overlapping. A configuration configured to be adjusted.

■ A structure in which index bodies of different lengths can be replaced as appropriate.

■ The indicator body has a screw or bellows-like structure that allows it to expand and contract.

■ Equipped with a reference point equivalent part that can be moved on the index body.

In addition to the above, there is too much to list, so I will omit it.

Examples of configurations that allow the length of the hanging body to be adjusted include the following.

■ An application of the above-mentioned configuration that allows adjustment of the length of the indicator body to a hanging body.

■It is constructed so that the hanging body is held at an appropriate position by clamps provided on the frame.

(2) A structure in which a hanging body or frame is provided with a large number of hangers at different positions above and below, and the frame or hanger is connected to the appropriate hangers.

In addition to the above, there is too much to list, so I will omit it.

The reference point display portion or the reference point equivalent portion may have an arrowhead shape, a needle shape, a pyramid shape, a hole shape, a dot shape, or the like. In addition, by marking an appropriate position on the display or indicator with a writing instrument such as chalk, a magnet, an adhesive tape, a screw, a pin, etc., or by memorizing the scale at that position, you can mark the reference point display area or the reference point. The configuration may be such that a section is provided. In other words, the reference point display section or the reference point equivalent section is not limited to the one shown in the example, but may be of any type as long as the operator can confirm its position and use it as an indicator for vehicle body repair work. Note that the reference point display section may be configured to measure the return to the normal position without contacting the reference point.

The hanging body, the display body, or the indicator body may include a stay or the like extending in the lateral direction as a part thereof.

In addition to the above examples, configurations that allow the hanging body or hanging tool to be locked to a reference point include hook-shaped, ring-shaped, hole-shaped, mushroom-shaped, etc., adhesive tape, screws, clamps, bolts, nuts, etc. The frame, hanging body, display body, or indicator body may be of any configuration as long as it can be locked to a reference point, such as a structure made of You may also use a tape measure or the like. Alternatively, the measurement may be performed by using reference points located at symmetrical positions on the vehicle body, without using the vehicle body dimension drawing. Alternatively, the measurement may be performed with the vehicle body placed on the ground.

Although the hanging body, display body, and indicator body of the above embodiment have appropriate lengths in the vertical direction, and the frame body has appropriate lengths in the front and back and left and right directions, it is important to note that each of the hanging bodies, display body, and indicator body has an appropriate length in the vertical direction. If possible, the length may be extremely shorter or longer than the illustrated example. For example, a part of the frame may have an appropriate vertical length, and the hanging body connected thereto may have an extremely short structure consisting only of magnets that can be latched to a reference point.

As is clear from the above description, the vehicle body measuring machines that do not require positioning work according to the first and second inventions have the following outstanding effects.

■ There is no need to perform the troublesome and difficult positioning work that takes up most of the time required to complete vehicle body measurements. Therefore, the drawbacks (b) and (d) of the prior art are completely eliminated.

■ If the car body moves during car body repair work, with conventional car body measuring machines of this type, the troublesome and difficult positioning work had to be redone each time, but with the car body measuring machine of the present invention, the car body Since the reference point display section or the laser irradiation mechanism is configured to automatically move in the same direction as the vehicle body in accordance with the movement of the vehicle, not only is there no need for positioning work, but there is also no need to redo the positioning work. Therefore, the drawbacks (c) and (,) of the prior art are completely eliminated.

■ As a result of the above, it is possible to complete accurate vehicle body measurements in a much shorter time than with conventional vehicle body measuring machines.
