It is desirable that the above-mentioned frame-like body has a box-like structure surrounded by a floor surface, both sides, and a ceiling portion, and a structure in which a plurality of frame-like bodies are connected to each other can be used. This frame can be formed by three-dimensionally combining steel materials such as H-shaped steel, I-shaped steel, and L-shaped steel. As the pressurizing device, an oil cylinder / air cylinder that expands and contracts by hydraulic pressure or air pressure, a jack that expands and contracts by a screw mechanism, or the like can be used. In this case, the base portion of the pressurizing device is attached to the frame, and the operating portion of the pressurizing device is structured so as to be able to abut against the vehicle body to be corrected, so that the pressing device can be operated in a timely manner. By supporting the force with the frame, the body can be pressurized and corrected. In addition, three or more pressurizing devices should be provided so that corrective work can be performed while simultaneously pressing three different parts of the deformed body. Is desirable. Also, if a mechanism capable of attaching and detaching an engagement attachment having a shape that is in close contact with or engaged with a part of the vehicle body is provided in the operating part of the pressure device, the engagement attachment can be attached to the pressure device as necessary. Thereby, the engagement attachment can be securely engaged with the vehicle body to perform pressurization and correction, thereby improving workability, safety, work accuracy, and the like. Furthermore, if a mechanism that allows the attachment for extension to be attached and detached is provided in the operating part of the pressurizing device, the extension attachment is attached to the pressurizing device as necessary, so that the deformed part of the vehicle body can be used as the operating part of the pressurizing device ft. Pressurization and correction work can be performed even when it is located away from the vehicle.

By attaching such a pressurizing device to the floor, both sides, and the ceiling of the frame, it is possible to press the car body from three different directions. It is possible to easily and accurately correct the pressure applied to the deformed vehicle body.

By enabling these pressurizing devices to move in the horizontal and vertical directions inside the frame-shaped body, it is possible to perform pressurization correction corresponding to the size of the vehicle body and the deformation state. Pressure correction can be performed accurately regardless of the position of the correction portion inside the frame.

By providing a vehicle body supporting member on the floor of the frame-like body on which a vehicle body to be mounted inside the frame-like body can be placed, the setting of the vehicle body becomes easy, and the vehicle body under repair work is also provided. Can be maintained stably, improving safety and correction accuracy.

By making the vehicle body support member vertically movable, it is possible to reliably hold the vehicle body according to the size of the vehicle body and the state of deformation, and it is possible to maintain the vehicle body at a height suitable for various pressure correction work. .

In addition, by making the vehicle body support member movable along the floor of the frame-shaped body, it becomes possible to hold the vehicle body in accordance with the size and deformation state of the vehicle body. And its holding position can be moved, thereby improving workability.

Furthermore, by making this vehicle body support member detachable from the floor surface of the frame-like body, Since the vehicle body support member can be removed from the frame at the time, the correction work is not hindered, and the space inside the frame can be effectively utilized. By providing an elevating device capable of lifting the loaded vehicle body and a vehicle body holding device for holding the lifted vehicle body inside the frame-shaped body, the deformed vehicle body is loaded into the frame-shaped body. Then, the vehicle body is lifted up to an appropriate height according to its size by the lifting device, fixed by the vehicle body holding device, and pressure is applied to multiple parts of the vehicle body by multiple pressing devices to plastically deform the deformed part. Since the original shape can be restored, it is possible to carry out the corrective work accurately and safely in a short time regardless of the size of the vehicle body.

By providing the vehicle body holding device with a detachable connection aid for fixing the vehicle body, the vehicle body can be securely fixed using the connection aid suitable for the size and shape of the vehicle body. Work safety, workability and work accuracy are further improved.

In addition, by enabling the vehicle body holding device to be able to move up and down, the vehicle body can be held at a height suitable for the size, shape, and deformed state of the vehicle body, thereby improving workability.

In addition, by making the body holding device movable along the floor of the frame, it is possible to hold a position suitable for the size and shape of the vehicle body, thereby improving workability. In addition, any position of the deformed portion of the vehicle body can be easily corrected. Furthermore, by making the body holding device detachable from the floor of the frame, the body holding device can be detached from the frame when not in use, which hinders the correction work. _{C The} pressure device attached to the ceiling of the frame is suspended from the ceiling of the frame so that it can expand, contract, swing, and rotate. By fixing to the suspended member, it is possible to correct the pressure when the deformed part of the vehicle body is located away from the ceiling of the frame, and the pressing position and direction can be set as desired. As a result, it is possible to press the position corresponding to the size of the vehicle body and the deformed state from an appropriate direction to perform an accurate correction work. In addition, since the pressurizing device attached to the ceiling of the frame is fixed to the suspension member via a universal joint, the movable range in the pressurizing direction is expanded, which is suitable for the size and deformation state of the vehicle body. An accurate pressure correction can be performed. Furthermore, by providing reaction force supporting members for supporting the reaction force of the pressurizing device attached to the ceiling portion of the frame on both sides of the frame, a strong force can be applied even at a position distant from both sides of the frame. Since it becomes possible to perform pressure, it is easy to correct a relatively deformed vehicle body.

By enabling the reaction force support member to move in the front-rear direction of the frame, the reaction force of the pressure device can be supported at arbitrary positions on both sides according to the setting position of the pressure device. Therefore, workability is improved.

By disposing a locking member for detachably locking a locking member for locking the vehicle body at at least one point on the floor, ceiling, and both sides of the frame, the inside of the frame is formed. It is possible to lock the car body inserted into the car so that it does not move using the locking member, so that the car body can be fixed more reliably, and correction work for complicatedly deformed parts Also becomes easier. Although a chain or the like can be suitably used as the locking member, unlike the conventional method, a chain or the like is used only inside the frame-shaped body. There is no risk of causing a serious accident.

By making this locking tool detachable from the frame, it is possible to prevent the locking tool when not in use from interfering with the repair work. Work space can be used effectively and workability is improved.

In addition, by enabling the locking tool to move in the horizontal direction and the vertical direction, it becomes possible to lock a position suitable for the size and deformation state of the vehicle body. Further, it is possible to easily lock the deformed portion of the vehicle body at any position inside the frame-shaped body. In addition, by allowing the locking member to move along the ceiling of the frame, a part of the vehicle body is suspended from the locking member via the locking member and mounted inside the frame. Since it is possible to carry in and out of the frame, the workability of loading and unloading is improved.

Of the locking members, the locking members arranged on the front side and the back side of the frame-shaped body are attached to and detached from a plurality of engaging portions formed at portions of the front side and the back side of the frame-shaped body with different heights. By attaching via a possible bar material, it is possible to attach the locking device to the front and back sides of the frame only when necessary. Since it can be attached, the lock does not hinder the loading and unloading of the vehicle body into the frame.

Since the pressure device is automatically fixed to the floor, workability is improved, and safety during work and work accuracy are also improved. When the load received by the pressurizing device is released, the pressurizing device becomes movable again, so that it is easy to change the pressurized portion or move the vehicle body.

Each of the above-mentioned pressurizing devices is provided with a detachable correction jig which is detachably engaged with a part of the vehicle body and transmits a pressing force of the pressurizing device to the vehicle body, so that an operating portion of the pressurizing device is directly applied. It is possible to safely and reliably pressurize parts that are difficult to contact or parts where the contact state is unstable.

By using an oil cylinder that expands and contracts with hydraulic pressure as each of the above-mentioned pressurizing devices, it becomes possible to operate the pressurizing device only with an oil pump without performing large-scale facility construction. It is possible to perform the correction while equally pressing the deformed part of the vehicle body and its vicinity by operating the same pressing device equally, and the correction accuracy is also excellent. It will be. Also, it is relatively easy to increase or decrease the number of pressurizing devices.
