According to the vehicle body modification apparatus of the present invention, since the modification is performed while pressing the vehicle body or a part thereof inserted into the frame-like body with a plurality of pressure devices, there is no need to fix or pull with a dedicated support member or chain as in the prior art. Corrective work can be safely performed in a short time. In addition, since the pressurization and modification of the deformation portion directly, the springback is extremely small and does not require advanced technology, so even a skilled person can make accurate modifications. In addition, since the correction work can be performed only inside the frame body, the effective use of the space can be achieved.

The frame shape is preferably a box-shaped structure surrounded by a floor, both sides, and a ceiling portion, and may be a structure in which a plurality of frame shapes are connected to each other. This frame shape can be formed by combining steel materials, such as H-beam, I-beam, and L-beam, three-dimensionally.

The pressurizing device may use an oil cylinder that is expanded or contracted by hydraulic pressure or air pressure, an air cylinder or a jackie which is expanded or expanded by a screw mechanism. In this case, the proximal end of the pressurizing device is attached to the frame body, and the actuating part of the pressurizing device can be brought into contact with the body part to be corrected to support the reaction force during the operation of the pressurizing device with the frame body to pressurize the body part. It is possible to correct. In addition, it is preferable to provide three or more pressurizing devices so that the modified vehicle body can perform the corrective work while simultaneously pressing the other three places. In addition, if a mechanism for attaching and detaching a fastening attachment having a shape that is in close contact with or engaging with a part of the vehicle body is provided on the operating part of the pressurizing device, the fastening attachment is attached to the pressure device as necessary. By mounting the fitting attachment to the vehicle body, it is possible to pressurize and correct it, thereby improving workability, safety and working accuracy.

By allowing these pressing devices to move horizontally and vertically in the frame body, it is possible to perform pressure correction corresponding to the size of the vehicle body or the deformation state, and the corrected portion of the body body can be accurately positioned at any position inside the frame body. Pressurized correction is possible.

The body of the frame-shaped body is provided with a vehicle body supporting member that can mount the vehicle body inserted into the frame-shaped body to facilitate the setting of the vehicle body, and also can stably support the vehicle body during the modification work, thereby improving safety and accuracy.

By allowing the body support member to move up and down, it is possible to reliably support it according to the body size and the deformed state, and to support the body at a height suitable for various pressurizing and modifying operations.

In addition, by allowing the body support member to move along the floor of the frame-like body, it is possible to carry out support corresponding to the size of the body or the deformation state. Is improved.

And since the body support member can be detached from the floor of the frame body, the body body support member can be separated from the frame body when not in use, so that the corrective work can be prevented and the space inside the frame body can be effectively utilized. have.

By including a lifting device capable of lifting the vehicle body loaded in the frame-shaped body, and a body support device for supporting the lifted vehicle body, the deformed vehicle body is charged into the frame-shaped body and the vehicle body is mounted according to its size in the lifting device. It is possible to lift it to an appropriate height and fix it with the body support device, and it is possible to restore the original shape by plastic deformation of the deformed parts by applying pressure to a plurality of parts of the car body with a plurality of pressurizing devices. It is possible to perform accurately and safely in a short time.

By providing a detachable attachment aid for fixing the body to the body support device, it is possible to reliably fix the vehicle body using a connection aid suitable for the size and shape of the vehicle. It is further improved.

Further, by allowing the vehicle body support device to be lifted and lowered, it is possible to maintain the height appropriate for the body size, shape, and deformation state, thereby improving workability.

Further, by allowing the vehicle body support device to move along the floor of the frame body, it becomes possible to support a position suitable for the vehicle body size and shape, thereby improving workability. It is also possible to easily modify the deformed portion of the vehicle body at any position.

By allowing the body support device to be detachable from the floor of the frame body, the body support device can be separated from the frame body when not in use, so that the space in the frame body can be effectively prevented from interfering with the modification work. You can use it.

Since it becomes possible, the press position, the press direction, etc. can be arbitrarily determined, the correct | correction operation | movement can be performed by pressing the position corresponding to a vehicle size or deformation state from an appropriate direction.

In addition, by stopping the pressing device attached to the ceiling of the frame-like body to the suspension member through the free joint, the movable range in the pressing direction is expanded, so that accurate pressure correction suitable for the size or deformation state of the vehicle body can be performed.

In addition, the reaction force supporting members for supporting the reaction force of the pressing device attached to the ceiling of the frame-shaped body are provided on both sides of the frame-shaped body so that it is possible to apply a strong pressure even at a position away from both sides of the frame-shaped body. Correction is also easy.

By making the reaction force supporting member moveable in the front-rear direction of the frame-like body, it becomes possible to support the reaction force of the pressurizing device at any position on both sides according to the setting position of the pressurizing device, thereby improving workability.

By arranging a locking zone for detachably locking the locking member for the vehicle system stop on at least one of the floor, ceiling, and both sides of the frame-like body, the vehicle body loaded inside the frame-like body is stopped to stop using the locking member. This makes it possible to fix the vehicle body more reliably, thereby making it easier to correct complicated deformed parts. As the locking member, a chain or the like can be preferably used. However, unlike the conventional method, the chain is used only inside the frame-shaped body, so there is no fear of causing a serious accident even if the chain is broken.

By making the locking area detachable from the frame shape, the locking area when not in use can be prevented from interfering with the corrective work, so that the working space inside the limited frame shape can be effectively used, thereby improving workability.

In addition, by allowing the locking zone to be movable in the horizontal direction and the vertical direction, the position suitable for the size, shape and deformation state of the vehicle body can be locked.

This improves workability.

In addition, the pressurization device attached to the floor of the frame-like body is attached to the floor through a moving mechanism held on the floor by the load received by the pressurization device, so that the pressurization device is automatically fixed to the floor with the start of the pressure correction work, thereby improving workability. At the same time, the safety and working accuracy of the work are increased. When the load under pressure is released, the pressurizer becomes movable again, so that the pressurized portion can be easily changed or the vehicle body can be moved.

Each pressurizing device is provided with a detachable quartz jig which detachably engages a part of the vehicle body and transmits the pressing force of the pressurizing device to the vehicle body, making it difficult to directly contact the operating portion of the pressurizing device or in a part where the contact state becomes unstable. It is possible to safely and reliably pressurize.

By using oil cylinders that are stretched and operated hydraulically as the respective pressurizing devices, the pressurizing device can be operated only by the oil pump without carrying out a large-scale facility construction, and the like. Since it becomes possible to perform correction while pressurizing evenly, crystal precision is also excellent. It is also relatively easy to increase or decrease the number of arrangement of the pressurizing device.

Since the oil pressure generator that operates the oil cylinder is detachably provided to the frame body, the oil pressure generator can be detached from the frame body and used in combination with another oil cylinder type pressure device, thereby improving convenience.

The wheel body is provided with a wheel for moving the frame body, a wheel lifting device for landing and storing the wheels, and a steering device for changing the direction of movement of the frame body, so that the wheels are grounded and driven to rotate. Since the entire correction apparatus can be driven, it is easy to move to the work place, to charge the vehicle body into the frame body, and to move to the storage place when not in operation. In addition, when the wheels are stored, the bottom of the frame body is grounded, so that the strength and durability of the frame body during the correction work are not a problem.

Further, by providing a wheel support member for mounting the wheels of the vehicle body inserted into the frame body inside the frame body, it is possible to support the vehicle body in a stable state even when the vehicle body deformed in the vicinity of the wheel is corrected. In addition, since the vehicle can be charged inside the frame body at the time of no operation, it can also be used as a garage, thereby making effective use of space.

By making the wheel support member detachable from the frame member, the wheel support member when not in use can be separated from the frame member, thereby preventing the modification work and contributing to the effective utilization of the space in the frame body.

In addition, in the vehicle body modification method of the vehicle of the present invention, in the body body modification method using the body body modification apparatus, the whole or part of the vehicle body of the vehicle is charged and charged into the frame-shaped body to which the plurality of pressurization devices for body pressure is attached. It is characterized in that plastic deformation of the vehicle body or part of the vehicle body is performed by applying a force to the three other parts of one vehicle body or part of the vehicle body by the plurality of pressurizing devices.
