SU55538A1 - Clamping jaws for filing templates - Google Patents

Description

Already known in general are devices for filing templates, equipped with limiting devices in the form of red-hot sponges with clamps.

The proposed device is of the type of such devices, but due to its design it allows the filing of templates and patterns of various designs, such as straight, cut, corner, radius, etc.

According to the invention, this is achieved by the fact that centers are placed between the walls of the jaws, which serve in processing various faces of the template for its installation by turning it in the desired position. These centers are arranged movable, for which they are installed on a ruler, movable in guide jaws. In addition, the device used a device for applying center recesses on the templates, consisting of two plates, one of which is provided with edges and clamps, as well as a hole for the center punch located in the second plate.

In FIG. 1 is a side view of the device; FIG. 2 is a section along the line AB of FIG. one; FIG. 3 - a section along the line CD; FIG. 4 shows a section along the EZH line of FIG. one; FIG. 5 is an axonometric view of the adaptation to the device for applying the center recesses on the templates to be filed.

The device consists of a T-shaped housing with jaws 1 with a recess and for placing a mold or pattern to be processed in it, a groove b for passing a screwdriver for tightening one of the moving centers 5 (Fig. 2) and a through groove for filing inner radii.

In addition, in the housing there are still a number of threaded holes for tightening the parts 6, 9, 12 described below.

In addition, there are two holes in the bottom of the housing, which serve as guides for vertical posts or rulers 2 connected to each other by a crossbar 3 with pin 7. A narrow groove d is attached to one of these openings (left) for the free passage of the screwed into line 2 of center 4, which is soldered to it during assembly.

Rulers 2 in their upper ends have threaded holes in which the aforementioned centers 4 and 5 are screwed.

The center 4 is a threaded pin with a sharpened end at 60 ° and a slot for a screwdriver on the opposite side.

The other center 5 is also a threaded pin with a slot for a screwdriver at one end and a square for screwing a wrench at the other (inner) end.

Rulers 2, after their installation to the required size, are fastened in the case with power supply, screws 6 and 1J, located along the height of the case in several places on both its sides.

To press the machined template to one of the jaws formed by the walls of the recess and during radius work, in which it is required to rotate at the centers, screws 12 with balls 5 are pressed against the product with help and embedded in the grooves of the screws 12 of the JO spring. ; .,:

To fix the product that does not need to be turned / rotate: bars 75, J4, 15, 16, 17 with holes for the passage of the ends of the screws 9 ,. provided with an annular groove (Fig. 3) for brads. Such a device allows the rotation of the screws 9 to move the strips in the axial direction of these screws. FIG. 4 the same pins 19 are provided in the slats J6, 17.

If it is necessary to apply a template or patterns on two, three or more points on the surface to be processed, then a special device, shown axonometrically in FIG. five.

It is a steel tile 20 with boards 21, 22, forming two faces with an exact angle of 90 °.

A punch 24, having a cone of 60, is inserted into the hole 23 of the plate 20.

This cone is the end of the rod inserted into the second plate 25, attached with the aid of the fixing pins 26 against the plate 20. The center punch 24,

the supplied thrust washer 27 entering the bore 28 is pulled away by a spring 29 abutting another washer 30 fixed to the end of the core 31 of the center punch 24.

The bracket 32 and the block 33, mounted on the slab 20, carry three clamps X, y, Z, by means of which the template is placed on the required center with the help of Ioganson's tiles 21, 22, and then clamped by the end the shank 31 is stabbed with a punch on the product.

To process the product to the desired size, it is necessary, after applying a center on it, to place it between the jaws / body so that the line of centers 4, 5 is just the right size below the upper face of the jaws / body.

To do this, it is sufficient to know exactly the distance from the upper face of the body to its lower face and from the center line 4, 5 to the upper face of the cross member 3. It goes without saying that if the difference of these two values is, for example, C, the measured distance between the lower face of the body and the upper face of the cross member 3 is H, then the required distance x of centers 4, 5 from the upper face of the body / will be equal.

Since the value of C for this device is constant, then, by measuring H with the help of Johansson tiles, it is possible to accurately determine the centers 4, 5.

After that, the template or template is inserted between the jaws (body) on the center, clamped by unscrewing the center 5 and the bars 18, 14, 15, 16, 17 and subjected to filing on the upper face of the body.

The subject matter of the invention.
