Abstract

PURPOSE:To prevent measurement from the generation of an error even if the positions of relative parts are shifted by arranging angle varying parts varying angles of respective suspending bodies from the base board by the weight of the base board in the front and back, right and left and their composite directions in accordance with the inclined angle of the car body. CONSTITUTION:The suspending bodies 9, weights 19 and reference parts 13 are set up to required conditions in accordance with the arrangement of a selected reference point of the car. The weights 19 are shifted from the Z axis direction of the car body 1, and even if the positions of the relative parts 17 are shifted, the positions of the reference parts 13 are automatically shifted in the same direction as said shift by the same distance as said shift through the angle varying parts 30, 31 changing the directions optionally by the weight of the base board 7. Thus, the direction and distance of the car reference point shifted from the normal position can be detected by observing the shift of the positions of the relative parts 17 from the reference parts 13.

Square hole 10 on the - side of the movable body 8 of the th and 6th horizontal beams 4
The J motorcycle is located at 11't, which corresponds to the centering position. A conical weight, which is the reference part 16, is fixed.

The movable body 8 is fixed to the horizontal beam by tightening the screw handle 15.

It has at its upper end a locking tool 16 composed of a rectangular plate-shaped magnet having a protrusion 5 on the upper side that fits into the hole 48 of the body base point to be locked, and the tip thereof is a relative part 17. A conical weight is placed at the lower end, and between them there is provided an anchor claw 19 extending in the vertical direction and consisting of a thin flexible lobe 18 (see FIG. 4). The locking tool 16 is provided with holes 20 and 21 at its center and at a position slightly off center, which have approximately the same diameter as the lobe 18 and pass through the hole 20 from bottom to top. Pass through one hole 21 from top to bottom. This allows hole 20.21 and rope 18
The rope 18 is held in the locking device 16 by the friction between the two and the length of the anchor claw 19 is adjusted by shifting the rope 18 with respect to the hole 20.21.

Next, an example of how to use this vehicle body measurement device will be explained.

Set the vehicle body 1 in an accurate horizontal state using the instructions described in the description of the disadvantages of this vehicle body measurement device below.

Two suitable sets (i.e., 4 locations) of vehicle body reference points located symmetrically on the undamaged part of the vehicle body 1 and one location on the damaged part of the vehicle body 1 that covers that position. Vehicle body base r (Select 9 points. While sliding each horizontal beam 4 and each movable body 8, check the arrangement dimensions of the four normally located vehicle body reference points described in the plan view of the commercially available vehicle body dimension diagram. At the same time, the four moving bodies 8 of the second and sixth horizontal bars 4 from the front are placed on the car body scraping machine.

The moving body 8 having the reference part 16 of the horizontal beam 4 near the front, which has the same dimensions as the normal arrangement of the vehicle body reference point at which the above-mentioned position shown in the same plan view is located, is placed on the vehicle body measuring machine. Deploy.

The length of each of the four corresponding hanging bodies 9 is set to be the same as the height from each of the four normally located vehicle body reference points to the vehicle body reference line described in the side view of the vehicle body dimension drawing. The length of the corresponding anchor pawl 19 is set to be the same as the height from the normal position of the vehicle body reference point around which the above-mentioned position shown in the side view is located to the vehicle body reference line.

By holding the base 7 by hand and delicately adjusting the position and angle of the base 7 integrally with the hanging body 9 in the front and back, left and right, and up and down directions, the locking portions 11 of each hanging body 9 can be adjusted to the required positions. The base 7 is suspended from the vehicle body 1 by positioning and locking it at a certain position of the vehicle body reference point. The locking tool 16 is locked to the vehicle body reference point at the above-mentioned position, and the anchor claw 19 is suspended from the vehicle body 1.

At this time, the reference part 16 straddles the normal position of the car body reference point that is hidden by a required distance n1 and adjusts the ZiI[ of the car body 1].
The relative portion 17 of the anchor pawl 19 is moved downward in the Zllq11 direction of the vehicle body 1 by the required distance from the current position of the vehicle body reference point;
6. does not represent. Then, by checking whether the position of the relative part 17 has shifted in the direction from the reference part 1, it can be determined whether the position of the vehicle body reference point has shifted in the direction from the normal position. You can know what is going on.

Conventional vehicle body measuring machines that hang from the base and anchor or the vehicle body are
It has the following drawbacks.

Generally speaking, the floor surface of a workshop such as an auto body repair shop may appear to be a horizontal surface at first glance, but it is not an exact horizontal surface and is usually somewhat slanted or uneven. When a car body is placed as it is on the floor of such a workshop, although it appears to be in a horizontal state at first glance, it is actually in a tilted state. An anchor hook suspended from such a tilted vehicle body shifts from the X-axis direction of the vehicle body, and accordingly, the position of the relative portion shifts in front and rear, left and right, or a combination of these directions. For this reason, if measurements are carried out as is, errors will occur due to the deviations, so it should not be useful as a car body g1 measuring instrument that requires accuracy on the order of 1.

That is, in order to perform measurements, it is necessary to set the vehicle body accurately in a horizontal state, which is extremely troublesome and takes a long time. An example of this work is as follows (see Figure 1).

Four vehicle body fixing stands 22 whose height can be freely adjusted are prepared, the vehicle body 1 is lifted to a height such that the four wheels of the vehicle body 1 are lifted, and the vehicle body 1 is supported on the four vehicle body fixing stands 22. While using a spirit level along the lower surface 2 of the rocker panel of the car body 1 parallel to the car body base line, open the inclination of the car body 1 in the X-axis direction, and further lower the left and right rocker panels +M.
The angle between i and 23 is undulating, and without using a level, the vehicle body 1 is tilted in the Y1ζ11 direction. Based on these measurement results, the heights of the four vehicle body fixing stands 22 are delicately adjusted. By repeating these horizontal measurements and adjusting the height of each vehicle body fixing stand 22 many times, the vehicle body 1 will gradually become accurately horizontal.
Since the lower surface 26 of the rocker panel is located at the lowest point of the vehicle body 1, it is often damaged by being hit when passing over a step between a sidewalk and a roadway or a road with large unevenness. In this case, it is difficult to use the lower surface 26 of the rocker panel as a reference, so the work of accurately setting the vehicle body 1 in a horizontal state becomes extremely difficult. ).

The present invention is a vehicle body opening machine in which a base and an anchor pawl are suspended from the vehicle body, and the anchor pawl is suspended from the ZIlq1 of the vehicle body due to the inclination of the vehicle body.
FIG. 5 shows a first embodiment of the present invention, which aims to provide a printing plate 411J that does not cause errors even if the position of the relative portion deviates from one direction in the front-rear, left-right, or a combination of these directions. This will be explained based on FIGS.
In FIG. 5, the vehicle body 1 is placed on a vehicle body fixing stand 22 and is shown in an extremely tilted state. ).

A base 7 is constituted by vertical bars 2 and horizontal bars 4, similar to the conventional vehicle body measuring machine in which a base and an anchor hook are suspended from the vehicle body. Each horizontal bar 4 consists of a horizontal bar 24 closer to the center and a horizontal bar 25 closer to the left and right, and the horizontal bars 25 closer to the left and right slide left and right inside the horizontal bar 24 closer to the center. The horizontal beam 4 is configured to be expandable and contractible. At both ends of each horizontal bar 24 closer to the center, there are provided handles 26 for stopping the sliding of the horizontal bars 25 closer to the left and right sides.

The hanging body 9 is composed of a square pipe having a locking part 11 at the upper end. The locking part 11 is connected to the hole 4 in the vehicle body record to be locked.
It consists of a rectangular plate 28 with a protrusion 27 conforming to the size 8 at the center of the lower side (see Figures 7a and 7b).

A square outer frame 29 is provided at the outer end of each of the second and third horizontal bars 25 from the front on the left and right sides.

Horizontal bars 25 directly below the locking portion 11 of each hanging body 9 and on each left and right side
An angle variable part 1161 is provided on the outer frame 29 of the vehicle body 1 to change the angle of each suspended body 9 with respect to the base 7 by the weight of the base 7 to the left, right, and a combination thereof after 6ij according to the inclination angle of the vehicle body 1. (The angle of the hanging body 9 in the front-rear direction with respect to the base 7 is shown in FIG. 5 by the arched arrow 2.) The angle variable part directly below the locking part 11 of the hanging body 9 is constructed by hanging figure 7-shaped hooks 6 and 4 provided at the center of the upper end of the square pipe and the lower end of the locking part 11, respectively. (See Figure 7b).

The angle variable portion 61 of the horizontal crosspiece 25 on the left and right sides allows the square inner frame 5, which is large enough to fit comfortably inside the outer frame 29, to be vertically rotatable between the front and rear inner walls of the outer frame. In addition, the inner frame 5 is pivoted between the left and right inner walls of the inner frame with a shaft 47 so as to be rotatable up and down (see FIG. 8). The hanging body 9 is passed through the inner frame, and the hanging body is held at an arbitrary position by tightening with a screw thread 7 of the inner frame.

The base 7 and the hanging body 9 are connected by this angle variable part filter 1.

A square board space is provided at the outer end of the left and right horizontal bars 25 closest to the front, and a space corresponding to the center of the inner frame of the second and sixth left and right horizontal bars 25 from the front is provided. Draw a dot-like mark on the 4Q section 1.

An anchor pawl 19 similar to that of the conventional vehicle body 31 surveying machine in which the base and weight are suspended from the vehicle body is provided.

To explain its use to Europe, like the conventional base mentioned above,
Hanging body 9 and anchor claw 1 are installed in accordance with the selected vehicle body reference point arrangement.
9 and the reference part 16, etc., are arranged and lengthened as required, and then hung on the vehicle body 1. 0, even if the vehicle body 1 is tilted, there is no need to set it in an accurate horizontal state, which is different from the conventional vehicle body J1ΔINIII in which the base and anchor claws are suspended from the vehicle body.

At this time, due to the inclination of the vehicle body 1, the anchor pawl 19 moves to the Z direction of the vehicle body 1.
Even if the position of the relative part 17 deviates from the axial direction, the position of the reference part 1 is automatically shifted in the same direction and by the same distance as the deviation. That is, the reference part 16 represents the position where the normal position of the vehicle body base, which is in a crooked position, is shifted downward in the vertical direction by a required distance, and the anchor claw 19
The relative portion 17 represents a position where the current position of the vehicle body reference point is shifted downward in the vertical direction by the distance of the station. By looking at how much the position of the relative part 17 deviates in the direction from the reference part 16, it can be determined in which direction the position of the vehicle body reference point has deviated from its normal position. It should be noted that the anchor claw 19 in the first embodiment has a 9th conical weight instead of a conical weight.
As shown in the figure, a vertically elongated cylindrical weight 39 may be provided, and a line may be drawn at an appropriate height on the circumferential surface of the weight to provide the relative portion 17. In this case, a hole 40 having a diameter slightly larger than the diameter of the cylindrical weight 39 is made in the Iida provided on the horizontal crosspiece 25 on the left and right sides, and the hole 40 is used as the reference part 1. Further, the structure for changing the length of the anchor claw 19 may not be provided.

To explain how to use it, depending on which side of the inner circumferential surface of the hole 40 in the base plate 1 the cylindrical weight slot 9 is in contact with, the vehicle body reference point is turned in the front, rear, left, or right direction. You can also know whether the relative part 17 and the reference part 1
3, it is possible to know how far the vehicle body reference point is vertically.

The angle variable section filter 1 in the first embodiment may have the following configuration (see FIG. 10).

The horizontal bar 4 is composed of a round pipe, and one ring-shaped movable body 8 that slides along the horizontal bar 4 is provided on each side of the horizontal bar 4, and a screw/endle 15 for stopping the sliding is attached to the movable body 8. Provided for.

On the second part of the movable body 8, two flanges 41 with a hole in the center are erected in parallel in the left-right direction, and the lower end of the hanging body 9 made of a square pipe is pivoted thereon. An angle variable portion 61' is configured to change the angle of each suspension body 9 relative to the base from left to right by the weight of the base depending on the inclination angle of the vehicle body. In addition, there is a short nine-fold fixed to the sliding part B that slides along the vertical bar 2G.

By passing the horizontal beam 4 through bearings (not shown) fitted into both ends of the suspension body 42, the angle of each hanging body 9 relative to the base can be changed back and forth by the weight of the base depending on the inclination angle of the vehicle body. The angle variable portion 61'' is configured on the side (around) a location at the same height as the connection location between each hanging body 9 and the base.

Next, a second embodiment of the present invention will be described with reference to FIGS. 11 and 12.

A rectangular plate-shaped iron base 7 extending in the X-axis and Y-axis directions of the vehicle body is provided. The base 7 is provided with a scale (not shown) consisting of a large number of vertical lines and horizontal lines.

The hanging body 9 has a locking portion 11 on two wheels that can be locked to a storage reference point, and has a magnet 4 at the lower end. The pipe consists of a thick pipe 44 with a thread cut on the inner peripheral surface and a thin pipe 45 with a thread cut on the outer peripheral surface (12th pipe).
(see figure). A part of the thin pipe 45 is made flat and a scale (not shown) is provided there, and by rotating the thin pipe within the thick pipe 44, the hanging body 9 can be expanded and contracted.

The locking part 11 of the hanging body 9 has two plate springs 12 having hemispherical flange 49 at the upper end, which are arranged back to back on the upper part of the hanging body 9, and between the two plate springs 12. A plate-like strike or par 50 is provided to sandwich the gap to prevent the gap from narrowing. This locking part 11 uses the weight of the base 7 to adjust the angle of each hanging body 9 with respect to the base 7 in the front-rear, left-right, and combined directions of the vehicle body in the hole at the base point of the vehicle body, depending on the inclination angle of the vehicle body. This is the angle variable part O that changes the angle.

In addition, depending on the inclination angle of the vehicle body, each hanging body 9 is
The angle variable part 31 that changes the angle with respect to the base 7 in front and back, left and right, and a combination of these directions is connected to a thick pipe 44.
At the bottom end of the magnet 43 and at the top end, there are 51 and 52 holes, respectively.
are arranged facing each other and hooked together. Four hanging bodies 9 having such a configuration are provided and connected to four locations on the base 7 that are not in a straight line using magnets 46.

The base 7 is provided with a front-rear rail 5 extending in the front-rear direction, and a laser 54 is provided along which the base 7 slides in the left-right direction.
A left-right laser oscillator 55 that oscillates is provided. Similarly, a left-right rail 56 extending in the left-right direction is provided, and a front-back laser oscillator 5B that slides along the rail and oscillates a laser 57 in the front-back direction is provided. The reference section 13 is constituted by these lasers 54 and 57.

The anchor claw 19 is composed of a rectangular plate having a protrusion on the lower side that fits into a hole in the focusing hole of the vehicle body to be locked.

It is composed of a pipe having a locking member 16 at its upper end and a transparent plate 59 at its lower end with a relative portion 17 provided at an arbitrary location.

The anchor claw 19 has a structure similar to that of the hanging body 9 and is extendable and retractable. At the upper ends of the lower end warped pipes of the locking devices 16 respectively), ribs 60 and 61 are provided facing each other to lock these.

Next, an example of how to use the second embodiment will be explained. By moving the magnet 4, laser oscillator 55, and base 7'' at the lower end of each hanging body 9, the hanging body 9 and the reference part 13 are placed in the car body opening machine according to the car body dimension drawing, and Hanging body 9
And set the anchor claw 19 to the required length. In this state, the base 7 and the anchor claw υ are suspended from the vehicle body as in the case of the first embodiment.

At this time, the laser 54.574 constituting the reference part 1
On the other hand, by looking at how far the position of the relative portion 17 has deviated in the direction, it is possible to know in which direction the vehicle body reference point has deviated from its normal position.

The fingers 51, 52, 60, 61 in the second embodiment may be replaced with commercially available universal joints. In addition, between the angle variable parts that change the angle of each hanging body 9 with respect to the base 7 in front and back, left and right, and in a combination of these directions, the weight of the base 7 is adjusted according to the inclination angle of the vehicle body. As in the example, it may be configured in the locking part 11 itself, or it may be configured by providing a universal joint or the like below the locking part 11.

Examples of the structure of the angleable part other than those described in the first embodiment or the second embodiment include a part where a hanging body is constructed with a string, a chain, a robe, a belt, etc. having 1J4i properties and is connected to the base. The hanging body on the plate part and the hanging body directly below the point connected to each locking part adjust the angle of each hanging body with respect to the base by the weight of the base according to the inclination angle of the vehicle body. (It may be configured as an angle variable part that changes a composite direction G.)

Further, the variable angle section may be of any type as long as it changes the angle of each suspended body with respect to the base in front and back, left and right, or a combination of these directions using the weight of the base according to the inclination angle of the vehicle body. Good too.

As shown in each of the above embodiments, angle change) qS is provided on the side of the connection point between each hanging body and the base, or on the side of a point at the same height, and on the side of each locking part. There are 15 emails.

In the present invention, if the hanging body is connected to three or more points that are not in a straight line with the base, the base can be hung normally from G to G, so the hanging body can be connected to 6 or more points. Good to have.

Even if the hanging body and the mold are bent in a dogleg shape, it is sufficient that they end up extending in the vertical direction. Similarly, the base also results in 'jJT, body's X limb and y
] It is sufficient if the structure extends in the li+b direction.

Depending on how the hanging body is placed, the base may lose its balance, so in that case, place the base at an appropriate position. A weight may be provided at the I location.

The number of master molds, horizontal bars, reference parts, relative parts, movable bodies, etc. may be increased as necessary.

A scale may be provided on the base, hanging body, mold, etc., as described above.
Alternatively, the work may be performed by applying a commercially available tape measure or the like without providing a scale. Further, the base plate 19 or the relative portion may be provided each time by applying a tape measure or the like to the base or template.

Some car body maintenance companies only deal with specific car models, in which case they manufacture the hangers 141, horizontal bars, model shapes, etc. in the required arrangement and length according to the car model, and use them as they are. You can also do this. In this case, there is no need for a configuration that allows the hanging body or the reference portion to be moved back and forth or left and right on the base, and a configuration that allows the length of the hanging body and the seed mold to be adjusted.

The vehicle body measurement device of the present invention, in which the base and the model are suspended from the vehicle body, uses the weight of the base to adjust the angle of each hanging body relative to the base in front, rear, left, right, and a combination of these directions, depending on the inclination angle of the vehicle body. The angle to be changed will be automatically shifted by the same distance as the shift in the same direction as the shift. Therefore, there is an overdraft effect in that even if the 411th place is shifted by one line, no error will occur in the split mold. Therefore, there are advantages such as eliminating the need for setting the vehicle body accurately and horizontally, which is extremely troublesome and takes a long time.
