Description

При лущении шпона (фанеры) устаноека чурако производитс  обычно .на основании отметок мелом, произведенных накладным шаблоном. В виду леточкости такого способа и вызьгоаемых им больших потерь самой ценной - заболонной части древесины, уже предлагалось производить центрирование чураков с 1Помош,ыо приводного клещевого механизма, а также примен ть при центриро(вании чураков опорьг, расположенные друг над другом .When peeling veneer (plywood), a Churako set-up is usually carried out on the basis of chalk marks produced by a patch pattern. In view of the badness of this method and the large losses it poses to the most valuable - the sapwood part of the wood, it has already been proposed to center churak with the help of a tick driven mechanism, as well as to use it when centering the forages located one above the other.

В отличие от Э1-ого, в станке, составл ющем предмет изобретени , применены две пары приводных зажимов - клещевого с боков и опорных - оверху и снизу, кажда  пара групп которых размещена в общей перпендикул рной к оси бревна плоскости и получает в опорных своих элементах перемещени , симметричные относительно оои наметоч1ных цент1ров.In contrast to the E1, in the machine constituting the invention, two pairs of drive clamps — tick-sided and supporting — at the top and bottom — are used, each pair of groups of which is placed in a common plane perpendicular to the axis of the log and receives in its supporting elements displacements that are symmetrical with respect to the brighter centered centers.

На чертеже фиг. 1 показывает -вид такого станка сбоку; фиг. 2 -вид с торца; фиг. 3 - кинематическую схему лри-вода станка.In FIG. 1 shows a side view of such a machine; FIG. 2 - end view; FIG. 3 - kinematic diagram of Lree-water machine.

Станок состоит -из двух пар 1, 2 сход щихс  по 1вертикали стержней; .из двух пар клещей 7, сход щихс  по бокам, из двух дрелей 22, 22, приводного механизма и сгани ы.The machine consists of two pairs of 1, 2 rods converging along 1 vertical; .from two pairs of tongs 7, converging on the sides, from two drills 22, 22, a drive mechanism and a shaft.

Образующие зажимы стержни / и 2 устанавливают чураки центрами в горизонтальной плоскости, проход щей через ось сверл дрелей, а клещи 7 устанавливают чурак его центрами в вер-тикальной плоскости, также проход щей через ось оверл дрелей. Лини  пересечени  этих плоскостей образует одновременно ось сверл дрелей и ось практически наибольщего цилиндра, который можно вписать в контур данного чурака.The cores / and 2 that form the clamps set the blockheads with centers in the horizontal plane passing through the axis of the drill drills, and the tongs 7 set the blockheads with its centers in the vertical plane also passing through the axis of the drill overlays. The line of intersection of these planes forms at the same time the axis of the drill drills and the axis of the practically largest cylinder, which can be inscribed in the contour of this block.

Центро вка заканчиваетс  в момент касани  чурака всеми восемью зажимными плоскост ми клещей 7 и стержней 1, 2.The centering ends at the moment the block is touched by all eight clamping planes of tongs 7 and rods 1, 2.

По окончании центровки, одновременно обеим дрел м сообщаетс  поступательное движение (подача) дл  прооверлив-ани  центров.At the end of the alignment, at the same time, both drills are reported to have a forward movement (feed) for the turning centers.

Стержни 1 и 2 выполнены в виде винтов, осевое перемещение которых производитс  вращением гаек-шестерен 5 и 4. Верхние винты / имеют правую нарезку, а нижние 2 - левую или наоборот. ПрИ помощи кон)ических шестерен 5, 6, звездочки 15 и цепи Галл  зажимы привод тс  в действие от общего приводного механизма 12, 16, 17.The rods 1 and 2 are made in the form of screws, the axial movement of which is carried out by rotating the gear nuts 5 and 4. The upper screws / have right-cut, and the lower 2 - left or vice versa. With the aid of conical gears 5, 6, sprockets 15 and Gall chains, the clips are driven by a common drive mechanism 12, 16, 17.

Клещи 7 смыкаютс  под действием т г 8, движение которых пройзвс дктPliers 7 are closed under the action of T g 8, the movement of which projzv dkt
