``Prior Art'' Conventionally, this type of clamping device consists of a clamping device that is fixed via a rail attached to the work floor, and a clamping device that is installed at both ends of two widthwise pipes that make up the clamping device. From a simple structure consisting of four body clamps and a side pipe that fixes the body clamps to the side of the car, to a horse-shaped clamp device body that moves via a rail attached to the work floor, An autorail clamp mechanism consisting of a body clamp provided on each of the two clamp pipes constituting the horse-shaped clamp device body and a chain lock device that fixes the clamp device body, and a work floor similar in structure to the autorail clamp mechanism. It consists of a horse-shaped clamp device body that is installed movably, a body clamp provided on the clamp device body, and a chain lock device that moves along a rail attached to a work floor that fixes the clamp device body. There is a rail clamp mechanism, etc.

In addition, a method for holding the upper pinch weld of the body is to remove automobile parts such as seats and doors that are normally attached to the body, and then insert a widthwise pipe with stepladder members at both ends through the body.
After the stepladder member and the widthwise pipe are clamped upward via a body clamp suspended from the widthwise pipe, the stepladder member and the widthwise pipe are fixed via tensioning of a chain lock device.

In addition, there is a somewhat complicated mechanism that is the same as the above-mentioned structure, and all have in common that they are equipped with a width direction pipe and a chain lock device.

In addition, equipment for restoring the damaged frame and body of the vehicle of Special Publication No. 56-54253, etc.
Technical documents such as No. 55-26185 regarding automobile body and frame modification machines can be found here and there.

[Problems to be Solved by the Invention] The clamping device and mechanism described in detail above have advantages such as being able to perform reliable clamping and being able to apply a tensile force to a damaged body or the like.

However, on the other hand, when clamping the body with a body clamp, additional equipment such as an elevator is required, and the clamping work requires time and effort, and the workability is poor.For example, the clamping device with the simplest mechanism , the body is lifted by an elevator, the body clamp is attached to the lower pinch felt, the pipe in the width direction is passed through the body clamp that corresponds to the body clamp, the pipe is fixed in the width direction, and the body clamp is fixed. Fixation of the body to the clamp device is completed by fixing with the side pipes, lowering and removing the elevator, etc.

Therefore, as mentioned above, the workability is very poor and a certain degree of skill is required.

In addition, the method of holding the upper pinch weld is used when installing the widthwise pipe through the body.
It is necessary to remove automobile parts such as doors, which is also a difficult task, and removal after repair is also difficult.

Furthermore, the clamping device occupies a large area with respect to the work floor, which may sometimes interfere with the work.

Furthermore, there are some problems in terms of cost, and there seems to be plenty of room for improvement.

``Means for Solving the Problems'' Therefore, a first object of the present invention is to provide a clamping device that can quickly and easily perform clamp mounting work and clamping work.

This is a clamping device for sheet metal.

A third object of the present invention is to provide a device that can easily and quickly clamp the upper pinch weld without removing parts such as seats and doors in the case of a vehicle without a lower pinch weld. .

The gist is a fixed plate fixed to the work floor with a long groove, a horizontal plate part placed on this fixed plate, and a square column etc. with a hollow part provided in this horizontal plate part. A stand case consisting of a column, a horizontal plate part of the stand case, a clamp fitting for fixing the fixing plate, and a long groove opened in the same direction as the long groove direction of the fixing plate inserted into the hollow part of the stand case. A stand with a cut groove and a lockshaft insertion hole perpendicular to the cut groove, and a lockshaft that is inserted into the cut groove of this stand, straddles the side edge of the bottom of the body, and reaches the upper pinch weld. It consists of a U-shaped clamp stay with an insertion hole, and a body clamp that clamps the upper pinch weld of the body that is fixed to this clamp stay. The body clamp is positioned on the upper pinch weld via the clamp stay inserted into the cut groove of the inserted stand, and the upper pinch weld is held at the center of the cheek of the body clamp α. Then, the stand and the clamp stay are fixed via the lock shaft, and then the stand case is fixed to the fixing plate using the clamp fitting.

"Action" Next, an overview of the action of the present invention will be explained.
In the first 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 on each fixed plate.

Then, 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 on the fixed plate.
Since the work is the same, I will only explain one side. (The same applies hereafter) and insert the body clamp into the cut groove of this stand.

The protruding portion of each clamp piece constituting this body clamp is structured to slightly protrude from the clamp component plate constituting the body clamp.

Therefore, by tightening the setscrews provided on each of the clamp pieces, the lower pinch weld is held between the protruding parts, and the protruding parts
Since the lower pinch weld is configured to protrude from the stand, the lower pinch weld clamped by this protrusion is held in a position slightly above the upper end surface of the stand.

After that, lower the garage jack and secure the front temporary clamp state (clamp held state; the same applies hereinafter).

Next, use a garage jack to lift the rear of the body, place the stand cases with the stands inserted on the fixed plates, and insert the body clamps into the cut grooves of the stands.

In addition, if the rear of the car is lifted using the garage jack at this time, the temporarily clamped state will be removed.
The front body clamp transitions from a tilted state to a substantially horizontal state. Similarly, the vehicle will be in a substantially horizontal position, for example on the floor.

The protruding portion of each clamp piece constituting this body clamp is structured to slightly protrude from the clamp component plate constituting the body clamp.

Therefore, by tightening the setscrews provided on each of the clamp pieces, the lower pinch weld is held between the protruding parts, and the protruding parts
Since the lower pinch weld is configured to protrude from the stand, the lower pinch weld clamped by this protrusion is held in a position slightly above the upper end surface of the stand.

After that, lower the garage jack and secure the temporary clamp at the rear.

Then, by inserting the conical shape of the lockshaft into the body clamp and lockshaft insertion holes of one of the clamp devices, the stand and the body clamp are secured to each other.

As mentioned above, the lockshaft insertion work is
When each clamping device is successively performed, the body clamp, the stand, and the stand case are fixed to the lower pinch weld of the automobile, respectively.

Therefore, next, the clamping device and the fixing plate in this state are fixed.

That is, after inserting the cutout strips of the clamp metal fittings and their extended horizontal tongues into the long grooves of the fixing plate into the left and right horizontal plate portions of the stand case, they respectively abut against the back surface of the fixing plate near the long grooves.

Next, when the inserted wedges are driven into the wedge insertion holes of the left and right clamp fittings, the fixing plate and the horizontal plate part of the stand case are clamped through the wedges and the horizontal tongues of the clamp fittings, and are fixed together. The plate and stand case are fixed.

When the above-described wedge insertion operation is performed for each clamp device in sequence, the stand case and stand of each clamp device are almost completely fixed under the lower pinch weld of the automobile.

After that, the lockshaft is cast and its prismatic shape is placed in the stand and body clamp. This driving operation holds the stand and body clamp in a horizontal and securely fixed state, and also attaches to the lower pinch weld of the body.
The body clamp of this clamping device is firmly fixed.

Once the clamping device has been firmly fixed, work such as repairing the body is carried out. In this case, since the body clamp is reliable and strong, secondary damage caused by the clamp coming off can be prevented.

After the above-mentioned work is completed, in order to remove the clamp device, lift one side of the body, for example, the front, using a garage jack, then remove the wedge to free the clamp fitting, and then remove the fixing plate. and the stand case.

After that, remove the lockshaft and
Unfasten the stand from the body clamp, then unscrew the set screw of the body clamp to release the body clamp from the lower pinch weld.

This frees the clamping device and allows it to be removed, allowing the garage jack to be lowered.

Next, the clamping device at the rear of the body is removed by performing the same operation as described above, but the method is the same as that described above, and the lowering of the body using a garage jack is almost the same.

The work of removing the clamp device is completed through the work of removing the front and rear clamp devices and the work of lowering the garage jack as described above.

Next, in the second invention, as in the first invention described above (hereinafter referred to as the first example), the operation of stopping the automobile on the fixed plate fixed to the work floor is basically the same. However, in this second invention,
Since garage jacks are not used, the fixing plate may be finely adjusted.

After that, for example, place the stand case in front of the body on the fixing plate (hereinafter, the left and right sides in the width direction of the car are the same work, so only one side will be explained. The same applies below), and the stand Insert the body clamp between the upright plates.

The body clamp clamps the lower pinch weld, and the protruding portions of the clamp pieces constituting the body clamp are constructed to protrude slightly from the clamp component plates constituting the day clamp.

Therefore, by tightening the setscrews provided on each of the clamp pieces, the lower pinch weld is held between the protruding parts, and the protruding parts
Since the lower pinch weld is configured to protrude from the stand, the lower pinch weld clamped by this protrusion is held in a position slightly above the upper end surface of the stand.

Next, when the lock pin is inserted into the lock pin insertion hole provided in the upright plate of the stand of the front clamp device and the clamp component plate of the body clamp, the front half of the body is temporarily locked by the body clamp, stand, lock pin, etc. It will be in a clamped state.

Preferably, one of the locking pins is inserted to place the body clamp in a substantially horizontal position.

Next, the stand cases at the rear of the body are placed on the fixed plates, and the body clamp is inserted between the upright plate parts of the stand.

The work of clamping the lower pinch weld with this body clamp is almost the same as that of the front side, so a description thereof will be omitted.

Next, the lock pins are inserted into the lock pin insertion holes provided in the upright plate of the stand of the rear clamp device and the clamp component plate of the body clamp (as mentioned above, depending on the case, the front lock pin may be inserted into the lock pin insertion holes). ), the rear half of the body is temporarily clamped using a body clamp, stand, lock pin, etc.

Thereafter, the clamping device in this state and the fixing plate are fixed, but since this operation is almost the same as in the first example described above, the explanation will be omitted.

Once the clamping device has been firmly fixed, work such as repairing the body is carried out.

In this case, since the body clamp is reliable and strong, secondary damage caused by the clamp coming off can be prevented.

After the above-mentioned work is completed, the clamping device is removed, but since the work is almost the same as in the first example described above, the explanation thereof will be omitted.

Next, in the third invention, the operation of stopping the automobile on the fixed plate fixed to the work floor is basically the same as in the first invention described above.

Then, 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 on the fixed plate.
Since the work is the same, I will only explain one side. The same applies hereinafter), and when one clamp stay is inserted into the cut groove of the stand, this one clamp stay is supported substantially at right angles to the stand.

Then, after pinching the upper pinch weld of the body with the protruding parts of each clamp part of the body clamp provided on the other clamp body,
Lower the garage jack and 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 (not shown)
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 temporarily clamped and fixed by each clamping device.

Thereafter, similarly to the first example, the fixing plate and stand case are fixed by inserting and driving wedges into the wedge insertion holes of the clamp fittings.

Then, similarly to the first example, the lockshaft is cast and the stand and clamp stay are firmly fixed, so that the body is fixed in a horizontal state via the clamp device.

Therefore, work such as repairing the body etc. will be carried out.

To remove the clamp device after completing this repair work, first lift the body using a garage jack, then remove the wedge to free the clamp metal fittings, and then attach the fixing plate to the stand case. Release the fixation and leave the stand case free.

After that, unscrew the set screw of the body clamp to release the body clamp from the upper pinch weld, remove the lockshaft, release the engagement between the stand and the clamp stay, and set the clamp stay in a free state. .

This allows the clamp stay to be removed freely and eliminates the need for it to be clamped to the upper pinch weld.

In this way, the removal operation is completed when all the members are disengaged and the clamp device is in a free state.

When the garage jack is lowered, the clamp mounting at the front of the body is first released, so the next step is to release and remove the clamp device at the rear of the body in the same way as described above. Then, the clamp mounting at the rear of the body is released.

Through the above-mentioned work or operation, the clamping work and repair work for the upper pinch weld of the body are all completed.

First, to explain the first invention in detail, reference numeral 1 denotes a fixing plate fixed to a work floor 2 via anchor bolts 3, and this fixing plate 1 preferably has several bolts (three bolts) depending on the size of the vehicle. ) long groove 4 has been opened. Reference numeral 5 denotes a stand case composed of a horizontal plate part 6 and a column body 8 such as a square column having a hollow part 7 erected from the horizontal plate part 6, and this stand case 5 is provided with a reinforcing stay 9. There is.

Then, a columnar stand 10 having the same shape as this is inserted into the hollow part 7 of this stand case 5, and the cut groove 11 opened in this stand case 10 is inserted into the upper surface of the stand case 5. It is configured to be located lower.

The cut groove 11 faces in the longitudinal direction of the automobile, in other words, it faces in the same direction as the long groove 4 of the fixed plate 1, and the insertion groove for the lockshaft, which will be described later, is perpendicular to the cut groove 11. Hole 1
2 have been established.

Reference numeral 13 denotes a body clamp, and this body clamp 13 includes a clamp component plate 15 having a rectangular lockshaft insertion hole 14 inserted into the cut groove 11 of the stand 10, and this clamp component plate 15.
It is composed of clamp pieces 17 and 17a that expand and contract through setscrews provided at both ends of the stand. body clamp 1
The lock shaft 20 is inserted into and removed from the insertion holes 12 and 14 so that the body clamp 13 is held in an inclined state or fixedly on the stand 10. It is something that

Specifically, when the conical end 20a of the lockshaft 20 is in the insertion hole 14 of the clamp component plate 15, the body clamp 13 is held in an inclined state, and the prismatic shape 20b of the rear part is in the insertion hole 14 of the clamp component plate 15.
body clamp 13 when it is in the insertion hole 14 of
is fixed in a horizontal position.

In the figure, reference numeral 18 indicates lock pin insertion holes provided on both sides of the insertion hole 14 of the clamp component plate 15.

21 is a clamp fitting; this clamp fitting 21

When the clamp fitting 21 is fitted to the fixing plate 1 and the stand case 5, the notch strip 22 extends horizontally to the stand case 5. The connecting portion 21b is inserted into the long groove 4 of the fixed plate 1, and the horizontal tongue piece 2 is in contact with the plate portion 6.
4 is brought into contact with the back surface of the fixed plate 1 near the long groove 4.

25 in the figure is a wedge.

The protruding portions of each clamp piece 17, 17a (hereinafter simply referred to as 17) protrude slightly from the clamp component plate 15 constituting the body clamp 13, and the body clamp 13 is When inserted into the cut groove 11 of the stand 10, the protruding portion is configured to slightly protrude from the upper end surface of the stand 10.

Therefore, when this body clamp 13 is inserted into the cut groove 11 of the stand 10, the lower pinch weld 40 is clamped by the protruding portion of each clamp piece 17 that slightly protrudes from the upper end surface of the stand 10. The structure is as follows:
The lower pinch weld 40 is held slightly above the stand 10.

Therefore, when clamping the body, the lower pinch weld 40 does not hit the upper end surface of the stand 10, but is clamped (the lower pinch weld 40 is clamped through a similar operation or work). Therefore, the explanation will be omitted below.)

Next, the second invention will be explained in detail.
In the invention described above, the same device as in the first invention is used, and specifically, the fixing plate 1, body clamp 13, clamp mold 21, and wedge 25 have the same shape and structure, so the description thereof will be omitted. is omitted.

In the figure, 30 is a stand, and this stand 30 includes a horizontal plate part 31 and two upright plates installed on the horizontal plate part 31 at a convenient distance, that is, a distance at which the clamp component plate 15 of the body clamp 13 is inserted. Plate part 32
The upright plate portion 32 has a large number of lock pin insertion holes 34 arranged in parallel.

Then, this insertion hole 34 and the body clamp 1

Specifically, the lower pinch weld 40 is held slightly above the stand 30.

Therefore, when clamping the body, the lower pinch weld 40 does not come into contact with the upper end surface of the upright plate portion 32 that constitutes the stand 30, but rather is held in place (a similar operation or work is not performed). Since the lower pinch weld 40 is clamped through the lower pinch weld 40, the explanation thereof will be omitted below.)

Next, the third invention will be explained in detail.
In this invention, the same instruments as those in the first and second inventions described above are used, and specifically, the fixing plate 1,
Since the body clamp 13, the clamp fitting 21, and the wedge 25 have the same shape and the same configuration, their explanation will be omitted.

Then, in this invention, the upper pinch weld 4

No. 3 is constructed in the same manner as the first and second inventions described above, and the protruding portion of the clamp piece 17 protrudes from the lower end surface of the support rod 47 of the other clamp stay 48, and this protruding portion is used for the upper pinch. It has a structure that holds the weld 41.

Therefore, the upper pinch weld 41 is connected to the support rod 4.
(The upper pinch weld 41 is clamped through a similar operation or work, so a description thereof will be omitted.)

However, as mentioned above, in each invention, the wedge 25 is driven into the clamp fitting 21, and the fixing plate 1
The device for fixing the stand case 5 and the stand 10 has been described in detail, but instead of this, a structure may be adopted in which the device is tightened using a tightening screw or the like provided on a clamp fitting (not shown). Any configuration in which the fixed plate 1, stand case 5, etc. are fixed is possible.

Next, the state of use of the present invention will be explained.

First, to explain the first invention in detail, the work floor 2
An automobile (not shown, the same applies hereinafter) is stopped on the fixed plates 1 fixed to the steps, and preferably each fixed plate 1 is positioned below the lower pinch weld 40 at the bottom of the step.

Next, after lifting one side of the body, for example, the front, using a garage jack (not shown, the same applies hereinafter), place the stand case 5 below the lower pinch weld 40, and insert the stand 10 into the stand case 5. Set up In this case, the lower pinch weld 40 is arranged so as to be positioned above the cut groove 11 of the stand 10 with a modification made for convenience.

Here, the set screw 16 is screwed in to clamp the lower pinch weld 40 between the clamp pieces 17 and 17a, and the lower pinch weld 40 is inserted into the lock shaft insertion holes 12 and 14 provided in the clamp component plate 15 of the stand 10 and the body clamp 13. Insert the lockshaft 20, and make sure that the conical shape 2 at the tip of the lockshaft 20
0a is the clamp component plate 15 of the body clamp 13
In this state, the body clamp 13 can be held in an inclined state, and the initial installation of the clamp device becomes extremely simple.

Next, when the garage jack is lowered and the body is lowered, the body clamp 13 that clamps the lower pinch weld 40 is held in an inclined state, and the front half of the body is held by the body clamp 1.
3. The clamp is held in place by the stand case 5, stand 10, etc.

Next, after lifting the rear part of the body using a garage jack (in this way,
By lifting the rear part, the front body clamp 13, which is normally in the above-mentioned inclined state, becomes almost horizontal. ), a stand case 5 is arranged below the lower pinch weld 40, and a stand 10 is inserted into this stand case 5.

In this case, the lower pinch weld 40 is appropriately modified and placed above the cut groove 11 of the stand 10.

Thereafter, the body clamp 13 is inserted into the cut groove 11 of the stand case 5, and the set screw 16 provided on the body clamp 13 is screwed back to loosen the clamp pieces 17, 17a. , 17a is inserted.
