Abstract

The head consists of a loosely rotating body (1) along the perimeter of which spring (10) loaded swinging levers (5) are placed on tangential pins (6) connected with pistons (4), controlled from a shoulder (2) by a pressure medium through the whole of the bearing pin (3) on one side and loaded with springs (9) on the other side.<IMAGE>

Vynález sa týká otočnej hydraulickej resp. pneumatickej hlavice na orientované nakladanie a odoberanie válcových obrobkov.BACKGROUND OF THE INVENTION pneumatic head for oriented loading and removal of cylindrical workpieces.

□e známa upinacia hlavica upevněná na pneumatickom zariadení na orientované nakladanie a odoberanie kruhových obrobkov ktorá prenáša na sústružníckych automatoch súčistky, ktorých hmotnost nepřesahuje cca 1 kg. Sůčiastky s vačšou hmotnostou vplyvom zotrvačných sil a nedostatočného trenia z hlavice vyklzávajú. Taktiež tento problém je vyriešený i manipuláciou so súčiastkami pri zastavenom vřetene pomocou pevných neotočných hlavic. Uvedené sposoby vyžadujú vačší cyklový čas stroja a zariadenie na vypínanie vřetena, ktoré bývá častým zdrojom porúch a dochádza к zbytočnej strate energie.A known clamping head mounted on a pneumatic device for oriented loading and unloading of circular workpieces, which transmits, on automatic lathes, machines of a weight not exceeding approximately 1 kg. Components with greater mass due to inertia forces and insufficient friction slip out of the head. Also, this problem is solved by manipulating the components while the spindle is stopped with fixed non-rotating heads. These methods require a greater cycle time of the machine and the spindle shut-off device, which is a frequent source of malfunctions and unnecessary energy loss.

Horeuvedené nedostatky odstraňuje hlavica na orientované nakladanie a odoberanie válcových kruhových obrobkov, na ktorej podstatou je, že je zložená z volné otočného telesa po obvode ktorého sú umiestnené na tangenciálnych čapoch perom odpružené výkyvné páky spojené s piestami, z jednej strany ovládané tlakovým médiom z ramena zariadenia cez otvor nosného Čapu a z druhej strany odpružené pružinami.The aforementioned drawbacks are eliminated by the head for oriented loading and removal of cylindrical circular workpieces, which consists in that it consists of a loose swivel body on the circumference of which are located on tangential pins spring-loaded pivoting levers connected to pistons, controlled by pressure medium from the arm of the device through the hole of the bearing pin and spring-loaded on the other side.

Claims

The cylindrical workpiece loading and removal head enables the loading and removal of workpieces and your weights directly into the rotating jaws of the machine spindle without stopping the spindle, thus increasing the machine's working performance.

The invention is schematically illustrated in the accompanying drawing.

The head for oriented loading and removal of cylindrical workpieces is composed of a free rotating body 11 on the circumference of which are located on tangential pins 8 by spring 10 pivoted levers connected to pistons 4 which are controlled from one side by pressure medium from arm 2 through hole of support pin 3 and The head is rotatable on a bearing 8 mounted on a bearing pin D of the device sealed with sealing rings 7.

On the surface of the workpiece 12, the head body 11 with spring-loaded pivoting levers 5 is pushed. and by performing an in-process transport, the workpiece 12 is released from the pivoting levers 5 of the head by switching off the pressure medium and springing the piston 6 by the spring 10 while simultaneously springing the tongue 10 of the pivoting lever 5.

OBJECT OF THE INVENTION

Head for oriented loading and removal of cylindrical workpieces comprising a free rotating body, characterized in that on the circumference of the free rotating body (1) are located on tangential pins (6) by spring (10) spring-loaded pivoting levers (5) connected to pistons (4) which, on the one hand, are actuated by the pressure medium from the arm (2) through the opening of the support pin (3) and on the other hand by spring (9).
