Abstract

The invention relates to automation equipment for mechanical engineering, instrument making, and is intended for the secondary orientation and supply of stepped cylindrical parts in automatic feed machines for automatic rotary and rotary conveyor lines. The purpose of the invention is to provide orientation of the cylindrical stepped parts. The device contains a cylindrical body 1 with two through vertical channels 3 and 4. The diameters of these channels are selected taking into account the free passage of the thick end of the oriented part. In the case there is a feeder having a through hole 8, a cradle made in the form of an aperture of the same diameter as both channels in the case, interconnected by two through slots of a width slightly larger than the diameter of the thin part of the part. One of the channels, spiral 6, is located on one side of the body and is made 1/2 of the spiral pitch, and the other is longitudinal. If the part goes to the hole 8 of the feeder with a thin end forward, then it cannot lower below. When the feeder is moved, the thin end of the part slides along the longitudinal groove and it is brought out in an oriented position on the axis of the channel 4, and then the pusher 12 unloads. If the part goes upward with a thin end, then when moving the feeder, the latter slides along the spiral groove 6 and the case of the feeder rotates 180 °. The part is then protruded by the pusher 12 along the output channel 4. 7 Il.

Description

The invention relates to the automation of mechanical engineering and instrumentation, and is intended for the secondary orientation and supply of stepped cylindrical parts in automatic machines for automatic rotary and rotor conveyor lines.

The purpose of the invention is to ensure the orientation of the cylindrical stepped parts "

On Fig.1 shows the device (without input tray and compartment.tel), a general view; FIG. 2 — view A on FIG. 3 — view B in FIG. 1; FIG. 4 shows a section B-B in FIG. in Fig „5 - section Г-Г on figo, with the wrong position of the part at the entrance to the device; figure 6 - the same, with the correct position; in fig - curvilinear groove (, cross section.

The loading device consists of a stationary cylindrical housing Ij having a longitudinal opening in which a feeder 2 is placed. Perpendicular to the longitudinal opening in the housing 1, a vertical outlet 3 is formed at a certain distance from each other and only the outgoing vertical opening 4 - through through all diameter of the case.

The diameter of the feeder 2 somewhat exceeds the length of the thick part of part 5, and the diameters of channels 3 and 4 allow free passage of the thick part of the part. A through-through spiral groove 6 is made on one side of the body between channels 3 and 4. This groove connects the vertical input channel 3 with output vertical channel 4.

The body also has a through longitudinal groove 7 connecting channel 4 (figb) at the exit point of the spiral groove with channel 3, forming a coaxial continuation of it. The width of each groove is smaller than the diameter of the thick part of the thal, and larger than the diameter of its furnace. move freely in one or the other slot

In the feeder 2, the lodgement is made in vi, n; e holes 8 of the same diameter as for channels 3 and 4 of the housing. At one of the ends of the feeder are two flats 9j with which the springs 10 or some other lock of the circumferential position of the tatels interact. The feeder is installed in the bearing 1 i J, with which it can

receive translational motion along its axis. The magnitude of this movement is clearly limited by two adjustable stops, ensuring that at the extreme positions of the feeder, the opening 8 with the channels 3 or 4 of the body

Above the input channel 3 of the case should be located a cut-off device,. providing separation of parts one by one from the flow to enter them into the device in the direction of the arrow I.

The device operates as follows.

In the initial position, the feeder 2 occupies the extreme right position and the channel 3 with the hole 8 in the feeder is aligned. In channel 3, the parts 5 are fed one by one in an unoriented position, i.e. any end down. If the part enters the thin end down, T; e. As it should be located for subsequent pressing into the tube of the spider unit, then part of the part gets into the hole 8 of the feeder, and it cannot go lower. Then the feeder is moved to the left until it stops, while the thin end of the part goes through the longitudinal groove 7 and it is brought to the axis of the channel 4, from where it is fed with the help of the pusher 12 in the direction of arrow K, and pressed into the tube (not shown)

If part 5 enters channel 3 with a thick end downwards, while moving the feeder to the left, a thin part of the part slides in the spiral groove 6 of the housing and turns together with the feeder around the rotary axis by 180 °, Latch 10 prevents accidental rotation of the feeder around its axis when there is no part in the device, and ensures that the holes of the feeder and the housing exactly match in the circumferential direction at the extreme positions of the feeder.
