Description

A utility model relates to devices for holding or setting a workpiece in a machined position with clamping means.

It is known “Device for basing sheets before cutting” [SU 685448 published 09.15.1979 IPC B23D 33/00], containing a table with radius grooves, a rotary bar, guide rails and side stops mounted on the table with the possibility of adjusting movement, axes, rigidly connected one end with guiding rulers, and feed assembly. The pivot plate is located under the table and is rigidly connected with other ends of the axes located in the radial grooves, and the side stops are installed on the outside of the guide lines interacting with the feed unit.

It is known "support-guiding device for basing the workpiece and the direction of movement of the cutting tool" [RU 2455129 published July 10, 2007 IPC B23D 51/02] containing a base with a supporting surface for the workpiece, a guide bar for the cutting tool, rearranged between the working position, in which the guide rail is located above the supporting surface of the base, and the idle position, and the holder on which the guide rail rests in the working position. Moreover, the holder and the guide rail are mounted movably relative to each other.

The disadvantages of these technical solutions is the design complexity.

The technical problem to be solved by the proposed utility model is the creation of a device with a simple design for basing sheet blanks.

The technical result of the proposed utility model is to simplify the design of the device for basing sheet blanks.

The essence of the proposed device for basing sheet blanks is that it contains a front support and guides.

New in the proposed utility model is that the front support is rigidly fixed on the rails and the rear support is additionally introduced, made with through grooves located along the longitudinal axis of the rear support. In the upper part of the rear support, end protrusions are made on which the rear support is mounted on guides with the possibility of movement. And on each of the longitudinal sides of the front and rear supports are installed with a given step mounting devices. A groove is made along the upper part of the front and rear supports. The fastening devices are made in the form of hinged levers with clamping screws. On the end sides of the front support, fixing eyes are made. Guides are made with limiters. The through grooves are elliptical.

In FIG. 1 shows a device for basing sheet blanks in axonometric projection.

In FIG. 2 shows an embodiment of the attachment device.

In FIG. 3 shows a view In a device for basing sheet blanks.

The device for basing sheet blanks contains guides (1), front support (2) and rear support (3). Hinged levers (6) with clamping screws (7) are fixed along the longitudinal side of the front support (2) and rear support (3) by means of brackets (4) and axles (5). Brackets (4) can be fixed with screws (12). A groove (13) is made along the upper side of the front and rear supports. On the end sides of the front support (2), fixing eyes (8) are made. The front support (2) is fixed on the guides (1), screws (9) screwed into the eyes (8). In the upper part of the rear support (3), end protrusions (10) are made. The rear support (3) is freely mounted on the tabs (10) on the guides (1). The rear support (3) is made with through grooves (11), for example, elliptical in shape. The guides (1) are made limiters (15). On the front and rear supports (2) and (3), a sheet blank (14) is placed.

A device for basing sheet blanks works as follows.

The front support (2) is fixedly mounted on the rails (1) with the screws (9) that are screwed into the mounting eyes (8). The guides (1) are mounted on the frame of a processing machine, such as a laser system. The rear support (3) under its own weight lies on the guides (1) on the plane of the end protrusions (10). The end protrusions (10) located in the upper part of the rear support (3) displace the center of mass of the rear support (3) below the working plane of the guides (1), which ensures a stable position of the rear support (3) on the guides (1) without fasteners. The hinged levers (6) in the initial position are fixed on the edge of the front support (2).

To base the workpiece, move the back support (3) manually, by hand grabbing through the through grooves (11), towards the front support (2) to the size of the sheet workpiece (14). Then, the required number of clamping screws (7) is unscrewed and the levers (6) on the axles (5) are folded, depending on the width of the sheet stock (14). The clamping screws (7) can be made inclined to create the required clamping force. Next, the sheet blank (14) is placed in the grooves (13) of the supports (2) and (3). Hinged levers (6) are returned to their original position, installing in the plane of the sheet stock (14). The clamping screws (7) fix the hinged levers (6) with the sheet blank (14) on the front and rear supports (2) and (3).

Then the sheet blank (14) is subjected to processing. After processing, the clamping screws (7) are loosened, the rear support (3) is shifted and thus the processed sheet blank (14) is released. To prevent the back support (3) from slipping off, guides (15) are made on the guides (1).

Thus, the desired technical result of the utility model is achieved in the form of a simplification of the design.
