(54) DEVICE FOR FILLING FASTENING ELEMENTS

one

The invention relates to the field of assembly work.

It is known a device for driving fasteners, preferably nails, in a solid material structure, comprising magazines mounted on a housing with fasteners located therein, a feeding mechanism and a driving actuating element in the form of a striking striker.

In order to improve the quality of fastening and performance in the proposed device, the feeding mechanism is made in the form of a hinged cassette with one end on the body of the cassette with guides for mounting the magazine and a lever sprung relative to the cassette, pivotally connected by one condom to the body, and the other through the finger to the cassette, at the same time, the finger is passed through a through slot made on the cassette, as well as in the form of a spring-loaded latch fixed in the cassette and rigidly mounted on the finger, acting on the magazine for its movement, and spring loaded ball retainers for the magazine stopper, when

This in the bottom of the cassette in the action area of the striker is made a window for the passage of the fastening element.

FIG. 1 shows the proposed device, a general view; in fig. 2 is a section along A-A in FIG. one; in fig. 3 is a section along BB in FIG. one.

The device comprises a housing 1, on which a driving working executive body is mounted in the form of a striking striker 2 and a feeding mechanism 3 with a magazine 4 located therein with fasteners 5.

The feeding mechanism 3 is made in the form of a body 1 of a cassette 7 pivotally fixed on an axis 6, in guides 8 of which a removable magazine 4 is installed, spring loaded 9 with respect to the cassette lever 10, pivotally connected at one end to the housing , while the finger is passed through the through slot 12, made on the cartridge. A spring-loaded leaf spring 13, the latch 14 is fixed to the finger 11 and is located in the cassette for interacting with the magazine as it moves. In the zone of action of the striker in the bottom of the cassette, a window 15 is made for the passage of a closable fastener — a nail — and at least one spring-loaded ball lock 16 is mounted for locking the magazine, for which the magazine is made in the form of a tape with side slots arranged in a feed step. At the same time in the tape in step half-washer washers 17 are made, in the center of which a fastener is mounted - a nail for a tight fit.

The housing of the device is fixed on the rod-handle 18.

To center the fastener head in the working position of the device, in the barrel 19 of the striker head 2, a center cone 20 is made.

The device works as follows.

The worker holds the device on a long handle-bar 18. At the same time, by means of a pull spring 9, the lever 10 will be removed and the feeding mechanism 3 will take a deflected position. In this position, the device is pressed by the feeder 3 against the surface of a solid material (for example, against the walls of the mold), and the cassette 7 of the feeder 3 rotates on axis 6 in the direction of the striker head 2, and the head of the nail is pressed against the end of the striking part of the striker head. 2 and moves it to the striker position. The striker is moved because the frictional force holding the nail in the washer 17 of the magazine 4 is greater than the frictional force between the striker 2 and the walls of the barrel 19.

The nail head rests on the centering cone 20 and it is centered relative to the axis of the striker, while the spring 9 is tensioned, the lever 10 rotates about axis 21, and the finger 11 moves along the slit 12 to the opposite extreme position.

The device is in the working position. The striking force is forcedly actuated, for example, by the energy of an explosion. The ditch accelerates and strikes the nail, hammering it into the wall of the structure, with the head of the nail attacking the half-cutting washer 17, separating it from the tape of the magazine, passing with it

window 15 and nails in. The nailing process is completed. The device is retracted from the product, and the feeder cassette together with the magazine under the influence of the spring 9, the lever 10 and the finger 11 occupies a deflected initial position. Meanwhile, the finger 11 moves the latch 14, which with its end enters the groove 22. The magazine's belt locks it and moves it in the feed direction to the schag. The next nail is in its original position, and the tape is fixed by the ball of the latch 16. The impact head 2 takes up its original position by the force of gravity.

The device is intended primarily for work in hard-to-reach places, for example, for fastening gasket plates on the inner walls of molds. In this case, preferably use

carrying manual rod 18, which greatly facilitates the approach of the device to more or less distant driving sites.
