Description

[Detailed Description of the Invention] The present invention relates to a framework clamping device that is comprised of a stationary clamping platform and a movable clamping platform provided with a carry-in conveyor and a clamping tool, and is capable of accurately and efficiently clamping frameworks of different sizes.

In buildings using the Dry Method 1 method, architectural panels used as walls, floors, roofs, etc. are formed by attaching face materials to the front and back of a frame made by joining frame materials into a rectangular shape.
The width of the architectural panels can be selected depending on the location of use, as shown in Fig. 2, which is an integral multiple of the standard pitch P, such as 2 times the pitch P, 3 times the pitch y, and 4 times the width.
There are a wide variety of materials, such as those with a double pitch e, and therefore, the width of the framework F constituting the architectural panel varies depending on the width of the architectural panel.

On the other hand, such a framework F is formed by, for example, joining frame members made of channel steel into a rectangular shape and welding the joined parts while clamping.
Preparing for different widths reduces factory space and increases costs.

The present invention includes a stationary clamp table and a movable clamp table,
The object of the present invention is to provide a framework clamping device (hereinafter referred to as the device) that can easily and efficiently clamp frameworks with different widths, and one embodiment thereof will be described below with reference to the drawings.

In the figure, the device 1 of the present invention comprises a stationary clamping table 2 and a movable clamping table 3, and the stationary clamping table 2 and the movable clamping table 3 are provided with an input conveyor 4.5 and a clamping tool 6.
6,7.7.

The movable clamp table 3 runs on a rail 9 extending to the side of the stationary clamp table 2, and is released to the stationary clamp table 2 by a cylinder (not shown).

The carrying-in conveyors 4 and 5 are, for example, belt conveyors arranged in parallel on opposite sides of the stationary clamp table 2 and the movable clamp table 3, and raise and lower the upper plate 11 by opening and closing the cross link 10, for example. table lifter 1
It is attached via a second grade lifting platform, and when it is lifted, the frame F is carried in from the adjacent feed conveyor with its both ends protruding.

The framework F is formed by temporarily assembling a frame material f such as channel steel into a rectangular shape, and after joining the ends of the framework F, a panel for construction, for example, is formed by attaching a face material.

Said clamping tool 6.6.7.7 has a positioning pin 15.
15 and a clamp pin 16.16, said framework F
are arranged at the corners C of the protruding portions protruding from the carry-in conveyor 4.5.

The positioning pin 15 is located at an equal distance from the corner C of the framework F and can come into contact with the outer surface of the frame material f, and the positioning pin 15
is erected on a triangular mounting table 19 provided on the raised portion 17 of the stationary clamp table 2 and the movable clamp table 3.

The mounting table 19 is horizontally attached to the raised portion 17 via a support piece 20, and can place the corner C of the frame member f.

The clamp pin 16 is erected on the support piece 21 at the same interval as the positioning pin 15, and is attached to the frame member f at an angle of 45 degrees through the corner C. When the cylinder 23 is contracted, the cylinder 23 approaches the positioning pin 15 and presses the inner surface of the frame f, thereby allowing the frame f to be held between the positioning pin 15 and the positioning pin 15.

The carry-in conveyors 4 and 5 can raise the upper ends of the positioning pins 15 and clamp pins 16 to a position beyond the conveyance surface thereof, and when lowered, sink below the mounting table 19. 6.7 is released on the stationary clamp stand 2 so that the frame material F can be positioned at a predetermined width dimension.

However, in the device 1 of the present invention, the movable clamp table 3 is moved to set the width between the clamping tools 6 and 7 to the width of the framework F, and the temporarily assembled framework F is moved while the carry-in conveyors 4 and 5 are raised. is carried in, and the corner C thereof is placed on the mounting table 19 by its descent.

Thereafter, by contracting the cylinder 23, the frame material f is sandwiched and clamped between the positioning pin 15 and the clamp pin 16.

As described above, the positioning pins 15 position the outer surface of the frame material f and can be stretched by the clamp pins 16, so that the frame F is clamped into a predetermined shape whose external dimensions match the positioning pins 15.

In the normal lamp state, for example, use a welder to cut the corner C.
can be welded to complete framework F.

Furthermore, by moving the movable clamping table 3 as shown in Fig. 2, frameworks F of different widths can be clamped, which makes the work more efficient compared to the case where different devices are used for each framework F of different widths. In order to utilize the factory space, the number of clamps can be reduced compared to the case where, for example, clamps that go up and down are pre-installed for each width of the frame F, and the lamp fixtures are lowered when they become unnecessary. It is possible to reduce the cost of equipment.

Further, the gap between the carry-in conveyors 4 and 5 can be changed according to the width of the framework, and the framework F can also be moved stably.

As mentioned above, the device of the present invention is equipped with a stationary clamp table and a movable clamp table, each equipped with a carry-in conveyor and a clamp tool, and can easily clamp frames with different widths with accuracy and with the correct external dimensions. In addition to improving work efficiency, the moving conveyor allows for stable loading and unloading of frames.

In addition, in the device of the present invention, the movable clamp base can be released from the stationary clamp base using various means such as a chain device, screw connection, etc. in addition to the cylinder, and the clamp pin can also be set to a positioning pin using a similar means other than the cylinder. The device of the present invention can be modified in various ways, such as making it movable in both directions, and the device of the present invention can be used in many processes that require clamping, such as attaching face materials in addition to welding work.
