(54) ЧЕРТЕЖНЫЙ СТАНОК(54) DRAWING MACHINE

1one

Изобретение относитс к средствам оргтехники , а именно к чертежным станкам.The invention relates to office equipment, in particular to drawing machines.

Известен чертежный станок, содержащий раму, установленную на ней чертежную доску и средство дл фиксации доски на раме I.A drawing machine is known, comprising a frame, a drawing board mounted thereon and means for fixing the board on frame I.

Известный станок неудобен в пользовании , так как имеет несовершенный узел креплени доски на раме.The known machine is inconvenient to use, since it has an imperfect assembly for mounting the board on the frame.

Цель изобретени - повышение удобства в пользовании.The purpose of the invention is to improve ease of use.

Указанна цель достигаетс тем, что механизм перемещени упора каждого верхнего зажима состоит из установленного на раме и св занного с упором подпружиненного ползуна, имеющего продольное отверстие, регулировочного винта, расположенного в отверстии ползуна и эксцентрика с руко ткой , закрепленного на раме над головкой винта.This goal is achieved by the fact that the mechanism for moving the stop of each upper clamp consists of a spring-loaded slider mounted on the frame and connected to the stop, having a longitudinal hole, an adjusting screw located in the slider hole and an eccentric with a handle attached to the frame above the screw head.

На фиг. 1 показан чертежный станок со сн той доской, общий вид; на фиг. 2 - разрез А-А на фиг. 1, вид нижнего упора; на фиг. 3 - вид Б на фиг. 2, нижний упор; на фиг. 4 - разрез В-В на фиг. 1 верхний упор с зажимным устройством.FIG. 1 shows a drawing machine with a removal board, a general view; in fig. 2 shows section A-A in FIG. 1, bottom view; in fig. 3 is a view B in FIG. 2, bottom stop; in fig. 4 shows a section B-B in FIG. 1 top stop with clamping device.

Рама 1 выполнена за одно целое и имеет в своем составе три горизонтальных балки 2. Две верхние балки служат дл креплени чертежного прибора реечной системы, кронштейн 3 - дл креплени чертежного прибора пантографной системы.The frame 1 is made in one piece and incorporates three horizontal beams 2. The two upper beams serve to fasten the drawing device of a rack and pinion system, and the bracket 3 to fasten the drawing device of the pantograph system.

К нижней балке крепитс полочка 4 дл инструмента. На раме креп тс два нижних упора 5 доски с гребенкой 6. Два верхних подвижных зажима 7 имеют выступ, вход щий в вертикальный паз рамы и соединены с ползуном 8. Они несут на себе такие же упоры гребенками. В ползуне расположен регулировочный винт 9. На винте установлена пружина 10, котора одним концом упираетс в выступ рамы, а другим в ползун. Пружина посто нно поджимает винт и ползун с подвижным упором к эксцентрику 11 с руко ткой, который имеет возможность вращатьс вокруг оси 12. На раме установлена чертежна доска 13.A shelf 4 for the tool is attached to the lower beam. On the frame there are attached two lower stops 5 of the board with a comb 6. The two upper movable clamps 7 have a protrusion that fits into the vertical groove of the frame and is connected to the slider 8. They carry on them the same stops with the combs. An adjusting screw 9 is located in the slider. A screw 10 is mounted on the screw. It rests at one end against the frame lug, and the other end against the slider. The spring is constantly pressing the screw and slide with a movable stop to the eccentric 11 with a handle that has the ability to rotate around the axis 12. A drawing board 13 is mounted on the frame.

Механизм работает следующим образом.The mechanism works as follows.

Claims

The handles of both clips are raised to the upper position. Under the action of the springs, the sliders, together with the upper stops, rise to the upper position. The width of the board is measured and the distance between the upper and lower stops is checked. By rotating the screws for the square shanks, the distance between the stops is slightly more than the width of the board. Board 13 is set strictly symmetrically with respect to frame 1 and clamped downwards with the claws of the clamps. At the same time, the screws are adjusted in such a way that when the handles of the clamps are lowered, the teeth of the dies completely cut into the ribs of the board and the board rests on the plane of the stops. After that, the machine is ready for operation. To flip the board, it is enough to turn the grips of the clips to the upper position, while the upper stops, under the action of their springs, will rise and release the upper edge of the board. Sl in the board and turning it over again, install the lower stops so that the teeth of the dies enter the already existing ones, the depth of the clamps in the first position of the board. This ensures the unambiguity of the position of the board during the flips. Then turn the handles of the upper clips to the lower position and the board is clamped. In case of loosening the board fastening in the clips due to drying, use the adjusting screws. Invention The drawing machine, containing a frame, a drawing board mounted thereon and means for fixing the board on the frame, having lower stops and upper clamps, each of which consists of a stop and a mechanism for its vertical movement, characterized in that ease of use, the mechanism for moving the stop of each upper clamp consists of a spring-loaded slider mounted on the frame and connected to the stop, which has a longitudinal hole, an adjusting screw located in the slider hole and stsentrika a handle mounted on the frame above the screw head.
