Description

113The invention relates to the field of mechanical engineering and can be used for automatic machining of parts and tin rollers, in particular for mortise grinding of parts on a centerless grinding machine.

The purpose of the invention is to expand the technological capabilities and increase the reliability of the device by providing processing of various sizes of parts and eliminating parts skewing when being fed to the supporting knife and dispensed to the discharge tray.

FIG. 1 shows the device, a general view; in fig. 2 shows section A-A in FIG. one.

The device comprises a hopper 1 fixed on the machine bed, a supporting knife 2, vertically located power cylinder 3, on the rod 4 of which a prism 5 is installed, equipped with an adjustable stop 6. On the rod 7 of the power cylinder 8 there is a pusher 9 and an ejector 10. Between the bunker 1 and the supporting knife 2 is fixed on the machine bed of the discharge tray 11, which can rotate freely about the axis 12 and under the action of its own weight is constantly rising to the stop 6. Window 13 of the bunker I for dispensing parts 14 and located below the level of the working surface of the supporting knife 2.

The device works as follows.

In the initial position, the prism 5 with the stem 4 of the power ts1-shindra 3 is located in the lower position, and the stem 7 of the power cylinder 8 is extended so that the pusher 9 and the ejector 10 are above the window 13 of the bunker 1,

According to bunker 1, part 14 rolls into prism 5. The width of prism 5 is somewhat larger than the diameter of part 14 and ensures the capture of only one workpiece, excluding the penetration of the following OJTOK 4 power n.

the prism 5 makes an upward movement to the level of the working surface of the supporting knife 2, closing the window 13 of the hopper 1 with the plane of the prism 5, and the part 14 is located between the pusher 9 and the ejector 10. Simultaneously with the movement of the rod 4 RETURN TRAY 1 1 under the action of the stop 6 rotates about the axis 12 and does not interfere with the axial movement of the part 14. A command is given and the rod 7 by the pusher 9 moves the part 14 to the grinding zone. Then, a command is given to bring the grinding wheels closer and the grinding process begins. At the same time, the rod 4 with the prism 5 is lowered down, grabbing the next part from the hopper 1, and the discharge tray 11, turning relative to the axis 12, is lowered down until it receives the machined part 14.

At the end of the grinding process, the wheels are consumed and the puller 10 receives movement from the hydraulic cylinder 8 through the rod 7 in the direction of the hopper 1, dropping the machined part 14 into the outlet chute 1 1. When the rod 7 reaches its initial position, the cycle of operation is repeated.
