Description

The invention relates to devices for the orientation of machined parts, which are designed in conjunction with a metal cutting machine or adapted for use with n-them, for example rotary machines for moving, loading} the parts into the machining position, search or sorting.

Devices for secondary ordering of parts in rotary power supply machines are known, comprising sliders located in the rotary drum associated with toothed racks, a piece-dispensing mechanism for parts, and copiers for controlling this mechanism 1.

The disadvantage of these devices is the low reliability of the operation of the cut-off mechanisms of the piece-by-turn mechanism due to their contact with fixed copiers.

The proposed device differs from the mirror in that the copiers are mounted on the toothed racks of the sliders.

This increases the reliability of the device.

FIG. depicts a rotary power supply with a device for secondary orientation of parts, a longitudinal section; on the flg. 2 - section A-A of FIG. one; in fig. 3 (a, b, c) - three fixed positions of the device.

Since the proposed device is included in the rotor power supply, its structure is considered in the general design of the automaton.

The rotary automatic feeder contains a shaft /, with which the hopper 2 is rigidly connected, filled with the feeding parts 5 and communicating with the chutes 4 through the agitators 5 of the hopper 2. Each agitator 5 has a gear 6 which is engaged with the central wheel 7. At the exit From each chute 4 in the case 8, cut-off devices 9 and 10 of suppressed piecewise discharging mechanism parts are mounted, controlled by the cams // and 12, fixedly mounted on the rails 13. The drum 14 is equipped with a scraper 15 placed in the disk 16 mounted on the shaft /. With gear 15}, the rails 13, also placed in the disk 16 and rigidly connected to the sliders, are engaged; 17, which are placed in the drum 18, rigidly with: - shaft on the shaft. The sliders 17 are controlled by a fixed circular dial 19. Under the drums 14 are rigidly fixed to 16 receivers 20 with unambiguously oriented details.

R: The operation of the proposed device is also considered in conjunction with the operation of the rotary machine.

The rotary automatic feed operates in the following} C; EARING A LUM ... With the Brushcheki} shaft 1 gear 6, rolled around the central wheel 7, they turn on the agitators 5. At the same time, the parts located in the bunker 2 are caught by the agitators 5 and enter the heat chute 4. From a non-moving copier / 5 P1ri3od tf into a reciprocating movement of the slide / 7. The slats 13, which are rigidly connected to the sliders P, transform their reciprocating movement into reciprocating movement of the drums 14, which have three fixed positions with respect to the leakage 4.

The grip and the primary orientation of the parts occur in the agitator 5. The arrival of parts from the rotating drum 14 is determined by the cutters 9 and 10 controlled by the jams // and 12, which are rigidly mounted on the slats. 13.

In the neipeoM fixed position of the drum (Fig. 3A), the cut-offs 9, W are open. The downward movement of parts is limited by the cylindrical top of the drum 14. In the second fixed position (Fig. 3 b), cut 9 and 10 are closed.

The through diameter of the drum 15 is aligned with the chute 4. At the same time, the parts oriented with the large base down through the through diameter of the drum 14 into the receiver 20, and the parts oriented with the large base are held by the cutter 9 above the hole and 14.

In the third fixed position (. 3s), the cutter W is closed and holds the column of parts in heat 4, the cutter 9 is open. With estrus 4 combined deaf socket hole of the drum 14 into which the part is fed, oriented with the large base upwards.

When the drum 14 is rotated to its original fixed position, the part is reoriented by 180 °.

Thus, in one cycle of work, one part passes through the mechanism of secondary orientation.

Ф о рм at vT and the invention

A device for the secondary orientation of parts such as rotation bodies, mainly rotary power supply machines, comprising

sliders located in the rotary drum associated with gear racks, the mechanism for the piece-issuing of parts and copiers designed to control this mechanism, characterized in that

increase its reliability in operation, copiers are mounted on rails.
