Description

The author's certificate No. 26051 describes a planer for riveting, in which an oval circumscribed arc is used, a guide surface designed to move an endless chain with grippers for rivets held between the two conical cutter cartridges along it. In the proposed machine for jointing rivets, the clamps for rivets are made in the form of carts equipped with elastic clamps for workpieces, and circular saws are used as tools.

In FIG. 1 depicts a side VIY machine; FIG. 2 is a side view of the grip, its carrying trolley, clamps and saws; FIG. 3 is the same in longitudinal section; FIG. 4-side view of a grab truck; FIG. 5-bottom view of the cart; FIG. 6 is a side view of the crossmember to rotate the grip; FIG. 7 is the same in cross section; FIG. 8-cross-section of the shop for blanks.

The proposed machine is used for fugovki edges of barrel staves of various shapes. The grips 7 of the machine are made in the form of carts (Fig. 1-3), designed according to the outline of barrel riveting and having convex

(2W)

over sa 2 around edges, made in the form of riveting chimes. Grabs / mounted on rollers 3, placed on rails. Along the edges of the claws / there are circular saws or mills 5, set at an angle corresponding to the outline of the barrel. Above the grip / installed elastic clamps 6 on the springs, pressing these clamps to the gripping surface.

When the machine is operating, the workpieces 7 of barreled rivets are applied to the clamps 7 under the clamps b so that the protrusions 7 of the convex pillars 2 are waxed into the chimes 8 of the riveting (Fig. 1-3). Further, the grip 7 on the rollers advances along the guides 4, and the saws or mills 5 produce the fugovka edges of the riveting at the desired angle, and the clips 6 hold the rivets on the grip. The projections 7 to ow 2-2, the riveting in the chimes 8, also prevent the rivets from moving in the longitudinal direction.

On machines, in which two operations are performed, namely, a fugovka of the side, rivets of rivets and cutting of the end edges of the rivets to give them standard sizes, rigid guides 8 are arranged in the form of elongated rings,

the grippers / which differ from those described above are placed in that they are mounted on platforms 77 (Figs. 1, 4, 5) and are rotatable on axles 9. On the lower part of the grips / there are fingers 10 (Fig. 5) that are facing down and pass through the arc-shaped notches, // available on the platform. Between the guides 8 there is a guide cross 72 with a groove 13 (Figs. 1, 6). The arrangement of the guide cross 72 between the guides 5 should be such that the mouth of the beginning of the groove is in the plane of the fingers 10 of the grips 7. Grips 7 sec the platforms 10 are located with their rollers on the guides 8 and are interconnected by an endless chain 14 (Fig. 1). At some distance from the rounded end parts of the guides 8 there is a hinged arcuate strip / 5 supported by the spring 16.

The action of the described machine is as follows. Initially, the riveting is applied from the magazine to the gripper 7, which is located longitudinally with respect to the guides 8 and the edges are machined as described above with circular saws or mills 5 (Fig. 1-3). In the process of further advancement of the grips 7 by an endless chain 14, the finger 10, and which is on the lower part of the grippers, extends into the cam groove 13 of the guide cross member 12 fixed between the guides 8, and due to the rotation of the groove, the gripper rotates 90 on the platform 77 in transverse position. When dzlney. At the same time, the grip falls under the spring strips 15-16, which at the same time press the riveting to the grip. The machining of the end edges of the rivets is carried out by circular saws 18 located near the strip 75. When the grip / is released from the action of the strip 75, the treated rivets fall off of the grip. With the further movement of the grippers, the latter are turned

again in the same position with the pbmsch of another guideboard / 2 with a groove.

The loading of rivets on the grippers can be done automatically. For this purpose, a magazine 18 is placed above the grips / (fig. 1, 8), on the bottom of which there is an opening 19 along the entire width of the box. The hole that occupies the lower part of the store and the side wall to the height of one riveting. The magazine 18 is motionlessly set in such a way that when the grippers move, the projections 7 on them will enter the chimes of 8 staves loaded into the box. When the grippers move, these protrusions 7 carry the rivets from the crate and the latter are located on the grippers 7, the projections 7 entering the chimes 8, and thus the riveting rests on the gripper in the correct position.

The subject matter of the invention
