(54) LOADING DEVICE

I

The invention relates to a machine tool industry, namely to the loading devices of milling machines.

There are known loading devices that support the mechanism for the piece-by-piece delivery of parts from the magazine, the feeder and the receiving tray, which perform the feeding, clamping and dropping of parts {.

Of the known loading devices, the closest to the technical essence is a single slot milling device, containing a detail store, a positioning prism with an emphasis and clamp, a pusher, a spring-loaded ejector, and a drive.

In this device, the loading of the next billet takes place after the removal of the tool and the lifting of the table to the extreme position, which takes additional time.

The aim of the invention is to improve the performance of the boot device by combining the loading and unloading times.

This is achieved in that the loading device includes a part-based shop, a prize-based prize with an emphasis. and sticking.

file transfer for transferring parts from the magazine to the clamping prism, spring loaded ejector and drive. The boot device is equipped with a ruler, made in the form of a rod with a bevel, acting through 5 roller on a spring-loaded ejector. The pusher is connected by means of a ball lock with a crossbeam connecting a ruler with a drive.

FIG. Figure 1 shows the kinematic scheme of the boot device; in fig. 2 - 10 device, general view; in fig. 3 - the initial position when loading; in fig. 4 - the final position when unloading.

The boot device is mounted on the table of the machine and consists of the store 1, the clamping prism 2 and the stop 3. Before the stop 3 is installed spring-loaded ejector 4.

On the rod of the hydraulic cylinder 5 there is fixed a traverse 6, mounted with the possibility of 20 movement along guide rails. Traverse 6 is connected to the pusher 7 by a ball lock 8. The ruler 9 is made in the form of a rod with a bevel, acting on the roller 10 of the spring-loaded ejector 4.

By means of the lever 11, the rod of the hydraulic cylinder 5 is connected with the claw 12 using the pusher 13 and the rocker arm 14.

The boot device operates as follows.

From the magazine 1, the parts roll down onto the gfizm-based 2.

The rod of the hydraulic cylinder 5 is moved to the right, and the pusher 7 feeds the next part into the cutting zone, simultaneously the compartment and holding the column of blanks in the shop 1 away from the working zone.

Simultaneously with the pusher 7, the ruler 9 moves, the roller 10 emerges from the bevel of the ruler, and the ejector 4 is lowered. Detail passes over it. The pusher 7 moves the item until it stops 3.

The ball lock 8 connecting the yoke 6 to the pusher 7, opens, and the yoke 6 moves relative to the stationary pusher 7. The clamp 12 using the lever 11, the pusher 13 and the rocker arm 14 clamps the part. Part processing occurs. After processing, the rod of the hydraulic cylinder 5 is moved to the left, returning the system of levers of sticking to the initial position, the part is expanded. The ruler 9 moves to the left and, with its bevel, hits the roller, 10 ejector 4. The ejector 4 n (with the action of a spring raises the end of the machined part above the support 3.

The pusher 7 occupies the extreme left position, at which time another part rolls down into a prism 2.

The hydraulic cylinder rod moves to the right. The pusher 7 moves the next part

to the cutting zone, pushing the finished part into the tray. The cycle is repeated.

The use of a pusher in the loading device, which holds a column of workpieces in the store and provides supply and discharge of parts, a movable crosshead and ruler with a spring-loaded ejector, increases the productivity of the loading device by combining the loading and unloading times, and improves the arrangement of the device.
