"Problem to be Solved by the Invention 1 The clamping device and mechanism detailed above have advantages such as being able to securely clamp the lamp and being able to apply tensile force to a damaged body, etc. However, on the other hand, When clamping a body with a clamp, additional equipment such as an elevator is required, and the clamping work requires time and effort, resulting in poor workability.For example, even when mounting a clamp with the simplest mechanism, the elevator Lifting the body, attaching the body clamp to the lower pinch weld, passing the pipe in the width direction to the corresponding body clamp, fixing the pipe in the width direction and fixing the body clamp with the side pipe, and lowering the elevator. The fixing of the body to the clamping device is completed by the work of removing and removing the body, and as mentioned above, the workability is poor and a certain degree of skill is required.Furthermore, the method of clamping the upper pinch weld is In order to penetrate the body, it is necessary to remove car parts such as seats and doors, which is a difficult task, and also difficult to remove after repair.Furthermore, the clamping device must be attached to the work floor. Occasionally, the area occupied becomes large, which hinders work.Furthermore, there are considerable problems in terms of cost, and there seems to be plenty of room for improvement.

Therefore, the present invention provides a clamping device that can quickly and easily perform clamp mounting work and clamping work. A stand case consisting of a fixed plate that is opened, a horizontal plate part that is placed on this fixed plate, and a column such as a square column with a hollow part provided in this horizontal plate part, or a stand case that is placed on this fixed plate. @, 21, a stand consisting of a horizontal plate part and an upright plate part in which insertion holes for lock pins are arranged in parallel at appropriate intervals in this horizontal plate part, and the horizontal plate part of this stand case or stand and the above-mentioned. A clamp fitting formed with a wedge insertion hole for fixing the fixing plate, a wedge inserted into the wedge insertion hole of the clamp fitting, and the fixing plate inserted into the hollow part of the stand case. A stand that has a kerf groove opened in the same direction as the long groove direction and a lock shaft insertion hole perpendicular to the kerf groove, and is inserted between the kerf groove of this stand or the upright plate part of the stand. It is a body clamp that clamps the lower pinch weld at the bottom of the body, which has an insertion hole for a lock shaft or a lock pin, and a cut groove of the stand inserted into the hollow part of the stand case placed on the fixed plate. The lower pinch weld is held between the body clamp inserted between the body clamp inserted between the stand and the upright plate section of the stand placed on the fixing plate, and then the stand and body clamp are connected to the lock shaft or lock pin. The stand case is then fixed to the fixing plate by inserting a wedge into the insertion hole of the clamp fitting.

"Operation J" Next, to explain the outline of the operation of the present invention, the automobile is stopped on fixed plates fixed to the work floor, and the lower pinch weld at the bottom of the step is positioned above each fixed plate. After that, use a garage jack to lift one side of the body, for example the front, and place the stand case in which the stand is inserted onto the fixed plate.
In the following, the work is the same on the left and right sides in the width direction of the car, so I will only explain one side (the same applies hereafter), and insert a body clamp into the groove of this stand, and use this body clamp to clamp the lower pinch weld. Next, insert the lock shaft into the lock shaft insertion hole of the body clamp and stand to secure the stand and body clamp, and then lower the garage jack to make the front of the body moored with the clamp. Now, use a garage jack to lift the rear of the body and place it on the stand case fixing plate where the stand is inserted, and insert the body clamp into the groove of this stand. Clamp the lower pinch weld with the clamp. Next, insert the lock shaft into the lock shaft insertion hole of the body clamp and stand.
A fixed state between the stand and the body clamp is ensured.

After that, lower the garage jack and make the rear of the body moored with a clamp. Therefore, the notched strips of the clamp fittings are inserted into the left and right horizontal plate portions of these stand cases, and the extended horizontal tongues thereof are inserted into the long grooves of the fixing plate, and then abutted against the back surface of the fixing plate near the long grooves, respectively. Next, when the wedges inserted and driven into the wedge insertion holes of the left and right clamp fittings are driven in, the fixing plate and the horizontal plate part of the stand case are sandwiched between the wedge and the horizontal tongue of the clamp fitting, and the fixing plate is held in place. and the stand case are fixed. After that, a lock shaft is installed to hold the body clamp horizontally and fixedly on the stand, and
The lower pinch weld on the body is held horizontally. By performing such fixing work with each clamp device,
The body is mounted on a clamp. Thereafter, work such as repair of the body is performed. In this case, secondary damage can be prevented because the body clamp is reliable and strong. To finish the work and remove the clamping device, use a garage jack to lift either side of the body, for example the front, and then remove the wedge to free the clamping plate and stand case. Unfix. After that, remove the lock shaft, release the fixation between the stand and the body clamp, and then screw back the set screw of the body clamp to release the body clamp from the lower pinch weld. This leaves the clamp device in a free state. Therefore, it is removed.

Here, descend the garage jacket. Subsequently, the clamping device at the rear of the body is removed in the same manner as described above, thereby completing the entire clamping device removal operation.

On the other hand, the method of clamping the upper pinch weld is to place the stand cases in which the stands are inserted on the fixed plates in the same way as described above, and insert one side of the clamp stay into the groove of the stand. The crumbusty is mounted approximately at right angles to the stand.

Next, after pinching the upper pinch weld of the body with a body clamp provided on the other clamp stay, lower the garage jack to link one clamp stay with the other clamp stay. At this time, it may be necessary to slightly modify the position of the stand and/or stand case in order to facilitate the cooperation between one clamp stay and the other clamp stay. In this way, the door frame of the body is held by the U-shaped clamp stay, and the upper pinch weld is held by the body clamp. If this operation is repeated at the rear of the body, the body will be clamped and moored by each clamp device. Thereafter, the fixing plate and stand case are fixed by inserting wedges into the wedge insertion holes of the clamp fittings in the same manner as described above. Then, by driving the lock shaft and fixing the stand and clamp stay, the body is fixed to the clamp device in a horizontal state. Therefore, when repair work is done on the body, etc., to remove the clamp device after the repair work is completed, lift the body using the garage jack and the key, and then remove the wedge to free the clamp fitting and attach it to the fixing plate. Release the fixation with the stand case and make the stand case free. After that, unthread the set screw of the body clamp to release the body clamp from the upper pinch weld, remove the lock shaft, release the engagement between the stand and the clamp stay, and set the clamp stay in a free state. do. This allows the clamp stay to be removed freely and eliminates the clamping of the upper pinch weld. In this way, all the members are disengaged, the clamp fitting becomes free, and it can be removed. Here, descend the garage jacket. As a result, the clamp mounting at the front of the body is first released. Next, remove the clamp device at the rear of the body using the same procedure as above.
The clamp mounting at the rear of the body is released. In this way, all clamp mounting on the body is released and the clamping device can be removed, so that all clamping and repair work on the upper pinch weld of the body is completed.
