(54) DEVICE FOR ORIENTATION OF CYLINDRICAL DETAILS WITH PROFILED END

one

The invention relates to the automation of technological processes in mechanical engineering and can be used in automatic loading devices for cylindrical parts with profiled ends, such as taps, sweeps when feeding them to a grinding machine.

A loading device is known, which contains a rotary drum with loading sockets — with locking spring-loaded levers and a mechanism for orienting a part along an angle, made in the form of a V-shaped lodgement installed coaxially with the part. The lodgment has a propelled profile of the sides with a permanent magnet 1 mounted in it.

The disadvantage of this device is the inability to orient the parts with four, five or more teeth in the angle: In addition, the propeller-shaped lodgement profile is more difficult to manufacture.

The purpose of the invention is to increase the reliability of orientation of parts along the line with a profiled end and expanding the technological capabilities of the device.

This goal is achieved by the fact that in the device for orientation of cylindrical parts with profiled ends, the angle orientation mechanism of the part is made in the form of an axially mounted glass piece fitted with a C-shaped elastic element located on its cylindrical surface, at one end of which a tooth with a bevel is attached, which interacts with detail.

Claims (3)

The device consists of a rotary drum 1 with loading sockets 2 and spring-loaded locking levers 3 swinging around axes 4, a corner orientation mechanism of the part, made in the form of a cup 5, having the ability to rotate around its axis at a predetermined angle carrying the pinion gear 6, slats 7, pre-assigned to rotate the rod-gear 6 with the cup 5. In the rotary drum I mounted a control fist 8, which is fixed to the housing 9, and a tapered rod 10, designed to release parts in nt its clamp B centers of the machine. The parts 11 are loaded into the rotary drum 1 from the feed tray 12 in which the parts are laid. The unloading of parts is provided by the collider 13 into the discharge tray 14. Plate 15 performs the role of an emphasis at the moment of orientation of part 11 along the corner when it hits a part of glass 5. Glass 5 has a C-shaped elastic element 16 which is attached to the glass with 5 screws 17. 18 with a bevel is rigidly connected to the elastic element 16. When rotating the glass 5, the tooth 18 with the bevel abuts against the protrusion 19 of the part 11. The device for orientation of the parts works as follows. Details AND, located in the feeding tray 12, are pre-oriented with profiled ends to one side. Going down the groove of the feeder 12, they fall into the loading slots 2 of the rotary drum 1. The rotary drum 1 has a periodic rotation. During the stop of the rotary drum 1, the following operations are performed at the same time: loading of parts into the loading slots; detail orientation 11 psg corner; thread grinding 11. 11. From feed tray 12, part 11 enters the loading slot 2. At this position, the spring-loaded locking lever 3 is in the unlocked position, interacting with one fender with the profile of the fist 8. In the next position, the part 11 is in the fixed position. In this position, the part is oriented at an angle at the time of the stand of the drum 1. Glass 5, moving forward, hits the part 11, and tooth 18 with a bevel in case of a touch on the pen of the mark is buried. When the cup 5 is rotated, the tooth 18 is squeezed by the elastic element 16 into the cavity of the part 11 and then, resting against the protrusion 19, makes it turn around its axis, overcoming the force of the spring-loaded locking lever 3. The flow cup 5 moves back, stops and turns to its original position. At the position when the part 11 is on the axis of the centers, the part is fixed by the front and rear center of the machine, and then the tapered rod 10, moving forward, unlocks the part 11 by pressing the end of the spring-loaded locking lever 3 until the part is completely processed . After that, the tapered rod 10 is returned to its original position and the lever 3 fixes the part 11. The front and rear center of the machine is retracted, the drum 1 rotates through a predetermined angle. In the unloading area, the locking spring-loaded lever 3, bumping over the profile of the cam 8, unlocks the part I, which is dumped by the pusher 13 into the discharge tray 14. The invention The device for orientation of cylindrical parts with profiled ends, containing a rotary drum with loading sockets and locking spring-loaded levers and an angle orientation mechanism for parts, characterized in that, in order to broaden the technological capabilities and increase the detail orientation angle reliability with a shaped t The mechanism for orientation of the part along the corner is made in the form of a glass installed coaxially to the part, fitted with a C-shaped elastic element located on its cylindrical surface, at one end of which is attached a tooth with a bevel that interacts with the part.
