Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automobile repair device for replacing a severely crushed front part of an automobile and correcting body distortion. multiple guide grooves are symmetrically drilled on the left and right sides of this lift, each movable plate is guided along this guide groove, and this movable plate is fixed at a position equidistant from the center line. The vehicle to be repaired is then placed horizontally and centrally on the surface plate.

The device, which restores a crushed car to its original shape by locally pulling it, has multiple rotatable pulling mechanisms placed around a base. ), each part is measured, and slight tension corrections are repeated each time. The work efficiency is extremely low and the quality is poor. In recent years, with the spread of front-wheel drive vehicles, high dimensional accuracy has been required for the front chassis, and as the quality of workers has declined, the emergence of repair equipment with high precision and excellent workability has been awaited. In response to this, the present inventor has developed a repair device using a horizontal surface plate (Japanese Patent Laid-Open No. 61-16158), and devised the present invention to further improve the workability. A detailed explanation will be given based on the drawings.

A horizontal surface plate 2 with a uniform surface is installed on a horizontal concrete base 1, and a well-known lift 3 is placed on the center line A of this surface plate 2. In the surface plate 2 on the front side of the lift 3, support guide grooves 4, 4 and lowerer mounting grooves 5, 5, which are parallel to the center line A and have a predetermined distance, are symmetrically bored. Since the distance to the center line A is accurate, these grooves can also be used as dimension lines. A pair of guide grooves 6, 6 are bored on the left and right sides of the lift 3 in a direction perpendicular to the center line A, and hanging pieces 8, 8 integral with the respective movable plates 7 are fitted into the guide grooves 6, 6. A movable plate 7 is arranged so as to be movable forward and backward with respect to a center line A. As shown in FIG. 1, the pair of guide grooves 6, 6 are parallel to each other and perpendicular to the center line A, and their respective ends are equidistant from the center line A. In order to fix the surface plate 2 in the position where the movable plates 7, 7 are pressed against the lift 3 side, the through hole 9 of the hanging piece 8 is
A through hole 10 corresponding to the size is bored in the leg 11, and the fixed rod 25 is inserted into the through hole 9, 10 to attach the movable plate 7, 7.
are fixed to the surface plate 2, parallel to the center line A, and at equal distances from each other. A threaded body 13 that loosely fits into a threaded shaft 12 supported at both ends.
hangs down from the lower surface of the movable plate 7, and a handle 14 is attached to the tip of this threaded shaft 12. As the handle 14 rotates, the movable plate 7 moves forward and backward.

Screw holes are provided in the four corners of the two supports 16 that support the branch pipe 15 at both ends, and screws are screwed into predetermined positions on the movable plate 7 (FIGS. 2, 4, and 5). The cylindrical part of the gripping tool 17 that grips the car's chassis is fitted into the branch tube 15 in advance, a set screw for fixing the gripping tool 17 is provided in the cylindrical part, and the gripping tool 17 is set in a predetermined position inside the spacer 18. bury a magnet in the A plurality of spacers 18 having dimensions for each vehicle type are prepared in advance.

Roser 19, which locally pulls the chassis,
It consists of a horizontal member, a swinging member, a cylinder, and a fitting member fitted into the lower mounting groove 5,
It is set as shown in Figure 3. Further, as shown in FIG. 6, the support stand 20 that holds the replacement chassis includes a horizontal body 21 having a dovetail groove, two pairs of grips 22 that are movable and can be fixed at arbitrary locations, and a horizontal body 21 that is movable and can be fixed at any location.
It consists of a threaded shaft 23 that adjusts the height of the guide groove 4, and a sliding piece 24 that is fitted into the guide groove 4.

Next, the operation of the present invention will be explained. The handle 14, which is integrated with the threaded shaft 12, is rotated to move the movable plates 7, 7 to the left and right (FIG. 2), and the car with its front part etc. crushed is moved onto the lift 3 and lifted. By rotating the handle 14 in the opposite direction, the movable plates 7, 7 are brought close to each other by the hanging piece 8 sliding along the guide groove 6. Since the guide grooves 6, 6 are parallel and symmetrical to the other guide grooves 6, 6 with respect to the center line A, the movement and position of the hanging piece 8 fitted in this guide groove 6 are also restricted, and the movable plate 7 can be located parallel to and equidistant from the center line A as shown in FIG. Rotation of the handle 14 is completed when the movable plates 7, 7 are brought closest to each other, and a fixing rod is inserted between the through holes 9, 10 in order to fix the movable plates 7, 7 at the same distance from the center line A. 25.

The gripping tool 17, which is movable along the branch pipe 15, is fixed by attaching a spacer 18 corresponding to the type of vehicle to the right side of the branch pipe 15 as shown in FIG. 4, and pressing it against this. The support 16 is fixed at a predetermined position on the movable plate 7, and the movable plate 7 is
is fixed at a predetermined distance, this support 16 also maintains a predetermined distance from the center line A. The distance from the center line of the car to the chassis gripping part B varies depending on the car model, but if the spacer 18 corresponding to the car type is attached to the branch pipe 15, the distance between the gripping tool 17 and the centerline A will always be the desired value. is maintained. With the gripping tool 17 set as shown in FIG. 4, the lift 3 is lowered, and the chassis gripping part B is supported by the gripping tool 17 (FIG. 5). The dimensions of the four grippers 17 and supports 16 are the same, and the branch pipes 15 are also parallel to each other and symmetrical with respect to the center line A, so the center line of the car placed on it is the center line of the surface plate 2. Surface plate 2 that not only matches A but also is horizontal
remain parallel to.

Set the lowerer 19 in the lowerer mounting groove 5,
Extend the chain from the car and connect it (Figure 3).
The distortion of the car is corrected by pulling the lowerer 19, and each time the dimensions of each part are measured using a gauge (not shown). A car held horizontally on centerline A always maintains its basic form even during this deformation. Therefore, based on the horizontal surface plate 2, it is possible to visually check the amount of correction, etc., and this is combined with quick and accurate measurement using the support guide groove 4 and the lower mounting groove 5, which can also be used as dimension lines. , the distortion correction work will be improved. After cutting off the crushed front chassis, place a new replacement chassis on the support stand 20, move it along the guide grooves 4, 4, and remove the gripping tool 1.
Press it against the car placed on 7, check the deviation, and correct it with Lowther 19. Since the support guide grooves 4 and 4 are parallel to and equidistant from the center line A, the replacement chassis is also aligned with the sensor line A.
The amount of distortion in the car caused by the collision can be seen at a glance. In this way, after repeatedly butting the replacement chassis and measuring it with a gauge, and after welding them together, the engine, tires, etc. are mounted, the gripping tool 17 is removed from the chassis gripping part B, and the handle 14 is rotated to remove the movable plate. Move 7 backward to finish the work.

As described above, the present invention arranges the lift 3 on the center line A of the surface plate 2 that is uniformly installed horizontally, and symmetrically drills a plurality of guide grooves 6 on the left and right sides of the lift 3. , a movable plate 7 on which a support 16 for supporting a vehicle is installed is guided along this guide groove 6,
Since the left and right movable plates 7 are fixed at positions equidistant from the center line A, the car can be placed on the center line A parallel to the surface plate 2, and the amount of strain can be measured three-dimensionally. Recognized, allowing for quick corrections and accurate measurements.
