Description

one

The invention relates to a machine tool industry and can be used for supplying parts such as bolts to automatic drilling, milling, etc., where a high accuracy of orientation of the part to the machining position is required.

The purpose of the invention is to increase the reliability of the device by ensuring reliable separation of one part and feeding it to the machining area in an oriented position.

FIG. 1 shows the boot device, general view; in fig. 2 is view A in FIG. 1; the braking assembly is not shown.

The loading device is fixed on the machine table and consists of body 1 on which drive 2 and parts 3 are mounted. A limiting melt 4 is located above the drive.

In case 1, a bracket 5 is fixed, on which on an immovable axis 6 a stop 7 is mounted with the possibility of rotation in a horizontal plane. The stop 7 is provided with a return spring 8 and a stop 9.

In the housing 1, a pusher 10 is installed with the possibility of reciprocating movement, ensuring the straight-line movement of the parts to be machined (distribution line) from the initial position, to the mounting prism 11 of the fixture (not shown). The pusher 10 has a prismatic notch P and two side working surfaces, one of which 12 is located on the storage side parallel to the parting line and serves as a cutter, the other 13 is curved with the ability to interact with the movable stop 7.

The axis of the accumulator is located at an angle to the supply channel 14, and the working surface of the movable stop 7 is located perpendicular to the axis of the accumulator.

Above the feed channel 14 in the area of issue of parts installed brake unit

part, made in the form of a rod 1 5 with a profiled end surface with (loaded by the spring 16.

The device works as follows.

In the initial position (Fig. 2), the flow of oriented parts 3 is held in the accumulator by the working surface of the stop 7, while the lower part 3 is on the sending line. The pusher 10 is in the extreme right position and does not interact with part 3.

During the working stroke, the pusher -10 starts to move to the left and the curved surface 13 comes into contact with the working surface of the stop 7 (FIG. 3) without interacting with the prismatic cutout part 3. With the further movement of the pusher 10 (FIG. 4), the curved surface 13 turns the stop 7 around the axis, interacts with a prismatic cut-out with part 3 and moves the latter along the feed channel 14, while the surface 12 cuts the moving part 8 from the rest: they are in the drive.

At the same time, the part 3, when moving, interacts with the profiled end surface q of the rod 15 of the braking assembly, presses against the surface of the feed channel and brakes. Since the speed of movement of the pusher 10 remains unchanged, a constant contact of the part along the edges of the prismatic notch along the entire path of movement is ensured.

In the area of the clamping device, the part 3 remains under the simultaneous Action of the rod 15 and the pusher 10 until the parts are clamped with the levers of the clamping device, after which the pusher 10 moves to the right, and the stop 7 is returned to its original position by the action of the spring 8. The next part comes from the accumulator to the supply channel.
