Abstract

PURPOSE:To make it possible to accurately perform the measuring and repair work of a car body within a short time, by measuring the positional relation of the target part provided to the stand fastened to the car body and the reference point of the car body by a retaining member. CONSTITUTION:A car body 2 is jacked up to be fixed onto mounting stands 23 for car repair work placed on the ground and car body reference points 1, 1, 1 (which are not positioned on a straight line) existing at three normal positions and one car body reference point 1a are selected on the basis of a car body blue print while the position on a stand 9 corresponding to the reference point 1a is determined on the basis of the scale 7 on the stand 9 and a dot like adhesive tape coming to a target part 8 is adhered to said position. Three fastening bodies 6 are attached to the car body reference points 1 to set a car body measuring instrument in parallel relation to the car body 2 and a car body retaining tool 10 constituted from a magnet is attracted to the car body reference point 1a to suspended an index member 13. The repair work of the car body is continued until the index member 12 is contacted with the target part 8 and reaches a position where the index member 13 is not slackened.

Description

[Detailed Description of the Invention] This invention relates to a vehicle body (“vehicle body” in ■ of this specification).
is used in a broad sense, including outer panels, frames, vehicle body reference points, etc., as is commonly used among auto body maintenance companies.

) This relates to a vehicle body measuring device that measures the vehicle body by being attached to the vehicle body.

The main types of conventional vehicle body measuring devices are: [1] centering gauge, [2] floor-standing vehicle body measuring device, and [3] vehicle body measuring device that uses laser beams.

etc. (Note that the vehicle body measurement devices [2] and [3] are not configured to be attached to the vehicle body.)

These vehicle body measurement devices will be explained below.

[1] Centering gauge l Configuration example Vehicle body reference point located in a symmetrical position (hereinafter referred to as "
The term "vehicle body reference point" has a broader meaning than is generally used among automobile body maintenance companies, and refers to a point that can serve as a reference point for dimensions when designing, manufacturing, or measuring an automobile body.

) A vehicle body reference point latching device for lifting the vehicle body is installed above both ends of the telescopic horizontal gauge, and a sighting device is installed in the center of the horizontal gauge. (When using, use 3 to 8 centering gauges with this configuration.) 2. Example of use: Based on a commercially available vehicle body dimension diagram (hereinafter referred to as vehicle body dimension diagram), find a symmetrical position. Select 3 to 8 sets of suitable vehicle body reference points located in Hang the gauges on the damaged area and each vehicle body reference point in the normal position and lower them. If the respective sights provided at the center do not overlap in a straight line when viewed from the front or rear of the vehicle body, it can be seen that the center line of the vehicle body has shifted. In other words, the centering gauge is created based on the idea that if all the sights appear in a straight line and overlap, then all the vehicle body reference points should be in the correct position. Therefore, repair the vehicle body until all the sights appear to overlap on -[a.

Disadvantages H) In general, it is impossible to judge whether or not a car body is in a normal condition unless you measure the position of the car body reference point, but centering gauges can only confirm the car body center line; Since it cannot measure the position of the vehicle, it has almost no function as a vehicle body measurement device.

For example, if a car collides head-on with a utility pole, etc., the center of the front of the car body will dent greatly backwards, and at the same time the left and right sides of the front part of the car body will be narrowed greatly toward the car body center line, so the car body reference point located there will be The position shifts significantly toward the rear and center, but when measuring the vehicle body in this state with a centering gauge, the sights of each gauge overlap in a straight line, and it is determined that the vehicle body is normal. A centering gauge that determines that the vehicle body is normal cannot be used as a vehicle body measurement device.

[2] Floor-mounted vehicle body measurement device 1 Configuration example There are usually about 8 vertical gauges that can be moved on the gauges arranged vertically and horizontally, and the vertical gauges are configured to be expandable and retractable like the antenna of a car radio. There is a contact part at the upper end that contacts the vehicle body reference point.

2. Convenient usage example: After placing the vehicle body measurement device on the ground under the vehicle body or on the repair table,
Before measuring the car body, the car body measurement device cannot be measured unless it is accurately parallel to the car body.

Therefore, first, we used a vertical gauge to make sure that the body measuring device was accurately parallel to the vehicle body, and then determined the installation position and angle t of the body measuring device.
l-adjust (hereinafter, this work will be referred to as parallel alignment work). Then, read the normal position of the vehicle body reference point of the damaged part from the vehicle body dimension drawing, and set the vertical gauge by expanding and contracting and moving it vertically and horizontally so that the contact part of the vertical gauge is located there.

After that, the vehicle body repair work is performed, and when the contact part of the vertical gauge and the vehicle body reference point of the damaged part come into accurate contact, it is possible to measure that the vehicle body reference point of the damaged part has been repaired to a normal position.

3 Disadvantage (b) Parallel alignment work is done by first adjusting the installation position of the car body measuring device so that the center line of the car body viewed from above and the center line of the car body measuring device exactly match, and then While maintaining the matched center line so that it does not shift, adjust the car body measuring device so that the thickness of the car body measurement device is exactly parallel to the frame or car body reference line seen from the side, and then match it as described above. While maintaining the center line and parallelism when viewed from the side, adjust and match the internal thickness of the vehicle body measurement device so that it is accurately parallel to the straight line connecting the symmetrical vehicle body reference points viewed from the front. However, just because this parallel alignment work is difficult, if it is done carelessly, it is extremely difficult and takes a long time.
If measurements were taken while the wings were bent from parallel, the modified car body would end up with a deviation of 3 vx, and an accuracy of xi units is required for the safe running of the car. This makes it useless as a vehicle body measurement device for vehicle body repair work.

(c) Car body repair work often involves repeatedly pushing and pulling the car body with a force of 3-10), so be sure to firmly place the car body on the ground or on the repair table to prevent it from moving. However, in reality, it is unavoidable for the car body to move by several centimeters to several tens of degrees during body repair work. Therefore, even if the parallel alignment work is carried out carefully, the car body will shift from the car body measuring machine during the car body repair work, resulting in an error in the car body measurement.

2) The vehicle body reference point is often located in a narrow place behind the floor of the vehicle body or the back of the frame, etc., and is often located behind the parts, so the contact part of the vertical gauge is in accurate contact with the vehicle body reference point. It is extremely difficult to visually determine whether or not the In such cases, the parts must be removed so that the head can be seen.

(e) Even if an attempt is made to set the contact part of the vertical gauge in a predetermined position, it may not be possible to set it because the damaged and bent vehicle body, 7 frame, etc. protrude and get in the way. in this case,
You can't set it up unless you first repair the car body with a rough idea.

Due to the above drawbacks, vehicle body measurements are often inaccurate.

[3] Vehicle body measurement device 1 using a laser base line Configuration example A vertical gauge that extends in the longitudinal direction of the vehicle body is placed on the left side of the vehicle body, and a horizontal gauge that extends in the left and right direction of the vehicle body is placed in the front of the vehicle body. Each gauge has legs that hold it at a fixed position and height, and is provided with a reflector that is movable over each gauge and that reflects the laser beam in the right angle direction, as well as a laser beam oscillator. On the other hand, lower the fishing scale that has a transparent scale to the reference point of the entire vehicle body.

2 Usage example Perform parallel alignment of two appropriate left-right symmetrical reference points of the normal vehicle body reference points. After lowering the fishing scale to the vehicle body reference point of the damaged area, read the normal position of the vehicle body reference point of the damaged area in the longitudinal direction from the vehicle body dimension drawing, and move the reflection 'a on the vertical gauge to direct the laser beam. Irradiate the correct position. Then, the car body is repaired until the laser beam hits a predetermined position on the fishing scale suspended from the car body reference point in the damaged area (at this point, the black spots in the longitudinal direction are corrected).

). Next, read the normal position in the left and right direction from the car body dimension drawing, move the reflector on the side gauge to irradiate the laser beam, and perform car body repair work in the same way (at this point, the correct position in the left and right direction is will be corrected).

3. Disadvantage (f) Because there are vertical and horizontal gauges, parallel alignment work is much more difficult and takes a longer time than with the floor-standing vehicle body measuring machine in [2].

(G) It has the same drawbacks as the floor-mounted vehicle body measurement device e→ in [2].

(g) Due to the nature of laser beams, it is possible to measure positional deviations in the direction perpendicular to the direction in which the beam travels.

It is not possible to measure positional deviations in the direction in which the light beam travels. Therefore, it is not possible to measure the deviations in the longitudinal and lateral directions at the same time, so when repairing a car body, first correct the gaps in the longitudinal direction and then finish. Later, the deviation in the left and right direction must be corrected, resulting in double effort. Moreover, in the actual correction work, while correcting the deviation in the left and right direction, the deviation inevitably occurs again in the front and back direction.
Correcting the displacement in the rear direction results in left and right displacements, which is extremely time consuming and troublesome. Furthermore, if the positions of a plurality of vehicle body reference points are different, the above operations must be repeated for each vehicle body reference point one by one, which is extremely time consuming and troublesome.

(January) If the angle of each gauge, laser beam source, or reflector becomes even slightly distorted due to rattling after a certain amount of use, vibration or impact during one operation, the fishing scale should be placed far away from it. In this case, the error in the laser beam will be amplified.

Due to the above drawbacks, measurements are often inaccurate.

(2) Since the gauges are placed around the car body, a lot of space is required, and the gauges also get in the way during car body repair work.

) Laser beams are dangerous and can cause blindness if they hit the eyes directly, so do not use light while working. You must always be careful not to stare into your eyes.

Also, laser ft, #j! The oscillator is expensive.

As explained above, when measuring with a body measuring machine, the body measuring machine must be installed accurately parallel to the vehicle body, but with conventional body measuring machines, this parallel alignment work takes a long time. In addition to this, there was no car body measuring machine that could measure easily, accurately, and quickly, so the automobile body maintenance industry has developed a body measuring machine that can easily, accurately, and quickly measure without parallel alignment work. For over 20 years, the automotive tool manufacturing industry and other industries have been working hard to develop a tool to meet that desire, but to no avail.

An object of the present invention is to eliminate the above-mentioned drawbacks of conventional vehicle body measuring machines, and to enable simple and accurate vehicle body measuring work in a short time without the need for parallel alignment work. An object of the present invention is to provide a vehicle body measuring device with a simple structure.

A first embodiment of the present invention will be explained with reference to FIGS. 1 and 2 (FIG. 1 is a side view showing a state in which the vehicle body measurement device of the vg1 embodiment is locked to the vehicle body (2), FIG. 2 is a perspective view showing only the vehicle body measurement device and the frame portion which is a part of the vehicle body (2) in FIG. 1. It is assumed that the vehicle body (2) in the first embodiment has the same height at the position of the normal vehicle body reference point +1).

Note that the locking body (6) is attached to the frame (The part that is attached to 91 is sometimes simply referred to as the "attachment part." Also, "able to attach" refers to other than the part that cannot be attached. For example, it is attached in advance and cannot be removed.) It has a magnet (5), has a string-like part (4) of an appropriate length above it, and has a hook-shaped vehicle body locking part ( Three locking bodies t6)f of the same length with 3) are provided, and the locking bodies are hooked onto three vehicle body reference points (1), t6), and t6) (11) that are appropriately spaced and not on a straight line. (In Kikiri 1valvr, "locking" means maintaining a contact state at that position.The point where the locking body (6) locks on the vehicle body (2) is It is sometimes simply referred to as a "locking point." Also, "lockable" refers to something other than a locking point.) Locking body (

A plate-shaped rectangular iron frame (9) is constructed to connect the two.

Since the latching member 19) is engaged with the frame body 9 by the magnet (5), the portion where it is engaged with the frame body 19) can be moved in the front and rear and left and right directions.

In addition, the three locking bodies (6), (6), and (6) make the vehicle body +21K. A vehicle body reference point (la') which is the tip of a conical weight, has a string-like part αυ above it, and is a part of the vehicle body (2) above it.
The front right side of the car body (2) was damaged, and the frame, etc. of that part moved rearward, inward, and upward, causing the car body reference point (1a) to reach the position of the car body reference point (1a). Vehicle body locking tool (II

Next, the measurement method of the first embodiment will be explained.

Lift the vehicle body (2), place the vehicle body (2) on a mounting table @ for vehicle body repair work placed on the ground 12'4, and fix it.
Based on the vehicle body dimension drawing, 3.

The magnets (5), (5), and (5) at the bottom of (6) are respectively attracted and engaged.

Next, connect the three locking bodies (6), (6), and (6) to the car body reference point (1) with the claw-shaped car body locking parts (3), (3), and (3). , (1), and (1), respectively, and this vehicle body measurement device is secured to the vehicle body (2)7.
At this point, the vehicle body measurement device becomes stable and accurately parallel to the vehicle body (2) without performing parallel alignment work.

In addition, a vehicle body locking tool (101 made of a magnet) is attracted to a vehicle body reference point (la') of the frame indicated by a dashed line, and an indicator body tt31 indicated by a solid line is suspended.

ζ Here, the deviation of the vehicle body reference point (la') in the front and rear, left and right, or up and down directions is measured as a positional deviation between the target part (8) and the index part (121).

Then, as shown by the one-dot line, the indicator part (12+ is the target part (8)
Until the index body Q31 comes into contact with and does not sag, that is, the vehicle body reference point (la') is in contact with the vehicle body reference point (1a
) The vehicle body (2) is repaired until it returns to the position shown in FIG.

Next, the second embodiment will be explained with reference to FIG. 3 (in FIG. 3, the display of the vehicle body except for the vehicle body reference point in FIG. 1, and the vertical and horizontal lines are omitted.

At this point, the vehicle body measurement device is stably and accurately parallel to the vehicle body without performing parallel alignment work, and the vehicle body reference point (la') is reached.
Swirling in the front/back, left/right, or up/down direction of the target area (
8) and the vehicle body reference point (la'). After that, the vehicle body reference point (la') is measured as the positional deviation between the vehicle body reference point (la') and the vehicle body reference point (la') until the vehicle body reference point (la') reaches the position of the target part (8), that is, the position of the vehicle body reference point (1a). The vehicle body modification work is continued until the vehicle returns, and the fact that the vehicle body reference point (1a/) has been modified to the normal position is measured by the coincidence between the vehicle body reference point (ta') and the target portion (8).

In addition, as shown in Figure 3, there is a conical part (14'a) at the top that can be adjusted vertically with a screw (not shown), and a part (14') extending upward in a U-shape. In addition, a frame (9) may be configured in which the target portion (8) is the tip of the conical portion (14'a). In this case, the strike position is located slightly above the vehicle body.

This is convenient when measuring the rat attachment part, etc. without removing the engine or strut. The shape of the upwardly extending part of the frame may be any shape, such as a U-shape, an inverted J-shape, an arch-shape, or a bar-shape, as long as it can extend upward and provide a target part. . Further, a magnet, a roller, etc. may be provided at the lower end of the portion extending upwardly of the frame, and the portion extending upwardly of the frame may be provided movably. It goes without saying that the configuration of the second embodiment can be applied to other embodiments of the present invention.

Next, the measurement method of the third embodiment will be explained.

Based on the car body dimension drawing, the parts are located at an appropriate distance and not in a straight line.

), select (1b).

Then, the positions of the horizontal beam (9b), the frame Qυ, and the CD are adjusted so that the target part (8) and (8) to 1 are located at the positions corresponding to the vehicle body reference points (1a) and (1b), respectively. Adjust using a commercially available tape measure, etc.

In addition, four vehicle body reference points (1), (1), (1)
.

Corresponding to the respective positions of the same (1), the horizontal bar (9c), the same (
9d) and the four locking bodies (
6), (6), (6), and (6) are set using a commercially available tape measure or the like.

Furthermore, each locking body (6), (6) is positioned based on the vehicle body dimension drawing so that the upper ends of the horizontal bars (9b), (9c), and (9d) are located at an appropriate constant distance from the vehicle body reference line. ).

The length of the same (6), the same (6) is 8 nuts (is, the same (

) and (13), the vehicle body measurement device is secured to the vehicle body.

At this point, the vehicle body measurement device is stably and accurately parallel to the vehicle body without performing parallel alignment work.

In addition, from the vehicle body reference point (la) and the same (1b) to the target point (
8), read the distance to (8) from the vehicle body dimension drawing, etc.
By memorizing the scale at the position corresponding to the distance from the vehicle body locking tool fl (I of 3), the scale is set as the index part 02, and then the index body α3. )
With the hook-shaped car body locking tools (11, 2 (II) penetrated through the holes (21, 2 (A)), place them at the car body reference point (la'
) and lb' (not shown).

Here, the indicator bodies +13 and (131) are in contact with the target parts (8) and (8), that is, the hole 4 of the frame Q1) and the indicator body (13) are not in a concentric state (Fig. ) are measured as the positions of the vehicle body reference points (la') and (ib') in the longitudinal and lateral directions.Furthermore, the index part tt3, the target part (8), and the reference point tt3 (not shown) are measured. The vertical deviation from the vehicle body reference point (1a, 1b') is measured as the vertical position shift of the vehicle body reference point (1a, 1b').

The only thing left to do is to make sure that the indicator body (l) does not touch the circumference of the hole (a) where the target part (8) is, as shown in Figure 1, and that the indicator part (121
until it matches the height of the target part (8), that is, the vehicle body reference point (la'), and the same (1b) coincides with the vehicle body reference point (la).

The car body was repaired until it returned to the same (lb) position, and the car body reference points (la and lb/) were adjusted to their normal positions. and the indicator part (1

Although the vehicle body measurement device of the present invention shown in FIG. 5 is a somewhat special example, magnetic disks (2elt
1 is fixed and a locking body (6) of nine configurations is provided, the upper end disk (1) is attached to the vehicle body (2) and locked at one place, and the lower end disk (1 ) K is adsorbed and fixed at one place.In this case, if the disks C2e and n at the upper and lower ends are extremely small, the frame (9)
Since it is not possible to lock the disk so as to maintain it stably parallel to the vehicle body (2), the α value of the disk (c) is stably parallel (in this case, it is somewhat unstable). It goes without saying that even if they are not parallel to each other, they do not need to be strictly and stably parallel as long as they do not interfere with measurement.) It must be as large as possible. That is,
To stably maintain the frame (9) parallel to the vehicle body (2) in the relevant locking points and locking points as seen from above or through the vehicle body 12) or the vehicle body measurement device. Three points that are not on a straight line and are appropriately separated to the extent that
It's called a point. ) It is necessary to lock and lock in a state where the above conceptually exists.

In addition, in the first to third embodiments, instead of the configuration of one locking point or one locking point, three or more locking points and locking points that are appropriately separated and not on one MH are used. However, it is clear that conceptually there are three or more appropriately spaced points that are not on a straight line in these locations as a whole. Therefore, regardless of the number of locking points or locking points, the locking body according to the present invention can be locked at a location on the vehicle body as a whole where three or more points that are not on the -M line and are located at appropriate distances exist conceptually. And, the structure is such that it can be attached to a location where three or more appropriately spaced points not on a straight line exist conceptually on the frame. Note that in this case, the locking location and the anchoring location do not need to be surfaces, but may be lines, points, or the like. Further, in FIG. 5, one locking body is provided, but two or more locking bodies may be provided. In any of the above cases, the frame has a configuration in which the hook passes between three or more appropriately spaced points that are not on a straight line and exist at the locking location of the locking body (in this specification, Like the frame in Figure 5,
Even if it is attached to the locking body at one point, the hook is considered to be passed between the three or more points mentioned above. ). In the vehicle body measurement device of the present invention, no matter what shape, structure, or combination it has, at least three or more appropriately spaced points that are not on a straight line at the locking point of the locking body can be connected. The component to be passed and the component to connect the locking body and the target part are used as a frame.

In this specification, expressions such as ~ book, ~ piece, ~ location, etc. are used, but these are for convenience, and the shape etc. are not limited by the name.

A locking body that locks at a location where there are three or more appropriately spaced points that are not on a straight line on the vehicle body, and that anchors at a location where there are three or more points that are appropriately spaced apart and that are not on a straight line. Even if a weight is provided, the frame may lose its balance depending on the arrangement of the anchoring points and the position of the center of gravity of the frame, so in such cases, place weights at appropriate positions on the frame and It may be stabilized.

In this specification, "the anchoring point is movable" means that the anchoring point can be moved in a direction including front and back, left and right, or a combination of these directions, and whether the anchoring point can be moved up or down or not. shall not be asked. In addition to the modes of movement of the locking point, in addition to those shown in the first or third embodiment, the locking body may be locked to an appropriate one of the many locking members located at different positions on the frame. When possible, when selecting an appropriate one from among the many locking bodies that are already attached to the frame, or when moving the frame to the anchoring point while the frame and the locking bodies are still attached. In some cases, it is possible to move.

The locking body and the index body may be locked to vehicle body reference points that are not located symmetrically. Furthermore, it may be configured to be locked at a location on the vehicle body other than the vehicle body reference point. For example, as shown in Figure WJ6, the vehicle body retaining part (3) of the retaining body (6) or the index body (13 of the vehicle body retaining tool 111i is composed of a magnet whose upper part is divided into branches, and the upper and lower Attack the long needle C24). Then, a magnet may be attached so that this needle point points to the vehicle body reference point, and the locking body (6) or indicator body Q3'Jk may be configured to be locked at a location on the vehicle body other than the vehicle body reference point. . In this case, the tip of the branch-like magnet and the needle c! Sometimes the distance between the tips of the nos is very long.

The car body locking part of the locking body and the car body locking tool of the index body may be ring-shaped, hole-shaped, mushroom-shaped, etc., in addition to the one shown in the example.
Any structure that can be secured to an appropriate location on the vehicle body may be used, such as adhesive tape, screws, brackets, bolts and nuts, or the like.

When the vehicle body measurement device of the present invention is locked to a vehicle body.

The frame is configured to have a portion located below the vehicle body locking portion of the locking body, but depending on the shape of that portion of the frame, etc. 44. It goes without saying that the locking body may be extremely shorter or longer than shown.

The locking body or the indicator body may include a stay or the like extending in the lateral direction as a part thereof. Further, the locking body or the indicator body may be in the shape of a band, chain, plate, etc., as long as it can support the frame body or the indicator part.

The indicator part may have an arrowhead shape, a needle shape, a pyramid shape, a hole shape, a dot shape, etc., and a writing instrument such as chalk or a dot magnet, an adhesive tape, or a screw may be placed at an appropriate position on the indicator body. Alternatively, the indicator portion may be formed by marking it with a bottle or the like.

The target portion may be configured by marking it with a drill marking tool such as chalk, sb, +-x>, screw, pin, protrusion, weight, or the like. Alternatively, a scale may be provided on the frame and the appropriate position of the scale may be memorized to be used as the target portion. Alternatively, a laser beam oscillator and a reflecting mirror may be provided on the frame so that the laser beam can be used as a target. Furthermore, the frame (2υ) of the third embodiment may be turned over and provided below the horizontal beam (9b) so that the target portion is located on the lower surface of the frame.

That is, the indicator portion and the target portion are not limited to those illustrated, but may be any other type as long as the operator can recognize the positions of the indicator portion and the target portion and use them as indicators for the vehicle body repair work.

An example of a configuration in which the length of the indicator body is adjustable is:

There are the following.

■ String-like, band-like, chain-like indicators that have part of them tied or rolled up, or that use length adjustment clips.

■ A structure in which parts of the index body are overlapped, and the length can be adjusted depending on the amount of overlap.

■ It is constructed so that it can be replaced with an indicator body of different length.

■ The index body itself has a bellows-like structure that allows it to expand and contract.

(2) There is no other example than the one provided with an index part that is movable on the index body, so the description will be omitted, but any structure may be used as long as the length of the index body can be adjusted.

Examples of configurations that allow adjustment of the distance between the vehicle body locking portion of the locking body and the frame include the following.

(2) The length of the locking body can be adjusted by applying the above-described structure that allows the length of the indicator body to be adjusted to the locking body.

■ It is constructed so that the locking body can be held at an appropriate position using clamps provided on the frame.

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

(2) A structure in which a frame is provided with a large number of latches at different positions above and below, and the latches are latched to appropriate latches.

(i) A configuration in which the two locking bodies located on the left and right move the locking points with the frame symmetrically.

In addition to the above, I won't list them too much, so I'll omit them here.

The distance between the vehicle body locking part of the locking body and the frame can be adjusted. 1. Even when locking the locking body at an appropriate location on the vehicle body at various heights, the frame can be parallel to the vehicle body. Any structure may be used as long as it is configured to be locked to PT He.

In the first embodiment, the case is explained in which the vehicle body has normal single reference point positions with the same height, but if there are vehicle body reference points with different heights, the locking body is adjusted according to the height. Or the length of the indicator body (il-just adjust it. In that case,
Most of the vehicle body reference points, which are located in symmetrical positions, are at the same height, so only one locking body on the front side can be moved at the point where it connects to the frame, and its length can be adjusted. In addition, the two rear locking bodies may have a structure in which the locking points of the two locking bodies are immovable and the length cannot be adjusted. In this case, the two locking bodies on the rear side are locked in a state where they are spread upward or widened in alignment with the vehicle body reference points located at symmetrical positions, and the degree of spread of these locking bodies is adjusted. Accordingly, adjust the length of the front locking body by calculation etc. so that it locks perpendicularly to an appropriate vehicle body reference point. Further, the present invention is not limited to this case, and the locking body may be locked diagonally in cases where an obstacle would get in the way if the locking body was locked vertically.

In the first embodiment, the attachment point with the frame is immovable,
Additionally, the attachment angle can be adjusted.

By installing three extendable rod-shaped locking bodies and adjusting the locking angle and length of the locking bodies appropriately through calculations, etc., three locations that are not in a straight line and are appropriately spaced in the front, rear, left, and right directions can be installed. It may be configured so that it can be locked to the vehicle body and the distance between the vehicle body and the frame can be adjusted.

Some body repair shops only handle specific car models, and in those cases, the frame, locking body, and index body are manufactured in advance with a certain positional relationship and length according to that car model. , it is sufficient to use it as it is, and therefore the positional relationship and length of the frame, the locking body, and the indicator body are configured to be non-adjustable.

The frame may be made of aluminum, plastic, etc. to make it lightweight, or may be made of transparent acrylic resin, etc. to make it easier to perform one operation. In these cases, it is not possible to attach the frame and the suspension body using magnets, so it is necessary to attach adhesive tape to the bottom of the suspension body, or drill a number of screw holes on the frame and attach them there. The lower part of the stopper can be fastened with screws, or the entire frame with multiple hooks can be used, and the lower end of the stopper can be hooked on the appropriate hook. You may let them. In addition, 1 lies parallel to the front and back direction 2
It is also possible to provide a frame with something like a book curtain rail, provide a hanger on a piece that can move within the rail, and hook the hanger at the bottom of the locking body to the hanger. .

The locking body may be attached to the frame using screws, adhesive tape, fitting, locking tools, etc., or the locking body and the frame may be integrally formed to lock the locking body to the frame. You may let them.

Furthermore, the number of locking bodies may be five or more.

In the first and third embodiments, it goes without saying that by locking the index body to the vehicle body reference point of the axle strut attachment section, the rotation of the vehicle body at the axle strut attachment section can be measured.

Three or more indicator bodies may be provided. in this case.

This has the effect of being able to simultaneously measure rolls in more locations on the vehicle body.

The horizontal bars of the third embodiment may intersect with the vertical bars at a position offset from the center.

Alternatively, a configuration may be adopted in which horizontal bars that can be moved separately are provided on the left and right sides of the vertical bars so that they do not intersect. Further, instead of the vertical beam and the horizontal beam, a beam extending in the vK diagonal direction may be combined. Also,
If the sliding of the horizontal rail is heavy, install rollers on the horizontal rail and guide rails on the vertical rail to make the rollers roll.

The horizontal beam may be moved. Also, magnets, screws,
The horizontal beam may be fixed to the vertical beam at a +U angle using fittings, bolts, nuts, etc. In this case, the vertical bar and the horizontal bar do not need to be configured at right angles except when fixed. Alternatively, the vertical bars may be moved along the horizontal bars. Note that one or more horizontal bars and one or more vertical bars may be provided. For example, vertical bar′
A configuration may be adopted in which two fcs and one horizontal bar are provided. Alternatively, the locking body may be locked to the vertical beam.

The frame may have a structure of two or more stages. For example, as shown in Figure 7, the upper disc-shaped part (9) of the frame (9)
e) to the three locking bodies (6), (6), and (6), and attach the target part (not shown) to the lower rectangular plate-shaped part (9f) of the frame (9). ).

A part of the frame in the first or third embodiment may be configured to extend upward, and the entire target portion may be used at the upper end of the extending part. In addition, in the first to third embodiments, a plate-shaped or crosspiece-shaped frame is provided, but the frame has three or more points that are appropriately spaced apart and not on a straight line at the anchoring location of the locking body. During f,
The hook is not limited to these as long as it can connect the locking body and the target part while passing the hook. In addition, when displaying a right angle on the frame, it is sufficient to display the right angle to the extent that the right angle between the front-rear direction and the left-right direction can be recognized, such as by displaying the right angle at the edge of a rectangular frame. Furthermore, in the case of a frame that does not have right angle markings, a commercially available right angle ruler or the like may be used.

The frame, the locking body, or the index body may be provided with a scale, or a commercially available tape measure or the like may be used without providing a scale.

Alternatively, measurements may be made using vehicle body reference points located at symmetrical positions on the vehicle body, without using the vehicle body dimension drawing. Further, in the first embodiment, the vehicle body is placed on a mounting table and measured, but the vehicle body may be measured while being placed on the ground or the like.

As is clear from the above description, the present invention has the following outstanding effects.

■ As explained in the example above, simply by locking this vehicle body measurement device to the vehicle body, it will naturally be accurately parallel to the vehicle body, so there is no need for extremely difficult and time-consuming parallel alignment work. This allows vehicle body measurement work to be carried out in a short period of time.

■ This car body measuring device uses a locking body to lock the frame and target parts to the car body, so even if the car body moves during car body repair work, it will move in the same way as the car body, so as mentioned above, The drawbacks (c) and (g) of the prior art are completely eliminated and accurate measurements can be made.

■ Since no space is required around the vehicle body, measurement work can be performed in a small space.

■ It has a simple structure, so there are very few elements that can break down, and it can be manufactured at low cost.

■ The vehicle body measuring instruments of the first to third embodiments can simultaneously determine the positional changes in the longitudinal, lateral, and vertical directions of the vehicle body reference point at a glance, and also constantly check the current vehicle body reference point while performing vehicle body modification work. Since it is possible to check the degree of blackout in the position, accurate vehicle body measurement work and vehicle body repair work can be carried out simply and clearly in a short time.

■ The vehicle body measuring instruments of the first and third embodiments use the index body to position the index section below the vehicle body reference point, so it is easy to judge the state of the vehicle body reference point position, and is superior to the conventional technology described above. ) and (e) are completely eliminated and accurate measurements can be made.

- The vehicle body measuring machines of the first to third embodiments do not use a laser beam excavator, so they are inexpensive and safe. Furthermore, the above-mentioned drawbacks of the prior art are completely eliminated, and accurate measurements can be made.

As described above, the vehicle body measuring machine of the present invention eliminates the above-mentioned drawbacks of conventional vehicle body measuring machines, does not require parallel alignment work, and can perform accurate vehicle body measuring work in a simple and straightforward manner in a short time.

This is a vehicle body measurement device with a simple structure.
