(54) СОСТАВНОЙ КОПИР(54) COMPOSITE COPIER

II

Изобретение относитс к вспомогательным устройствам дл металлообрабатывающих станков, а именно к устройствам дл обработки по копирам с помощью чувствительного элемента, движущегос вдоль контура копира, и предназначено дл обработки замкнутых, преимущественно пр моугольных контуров.The invention relates to ancillary devices for metalworking machines, namely, devices for machining copiers with a sensing element moving along the contour of a copier, and is intended for machining closed, preferably rectangular contours.

По основному авт. св. № 577116 известны составные копиры дл обработки замкнутого контура, содержащие г-образные элементы , установленные с возможностью-перемещени во взаимно перпендикул рных направлени х . Копиры снабжены вставками, закрепленными на элементах копира в местах их пересечени и смонтированными с возможностью перемещени вместе с ними 1.According to the main author. St. No. 577116 are known compound copiers for processing a closed contour containing g-shaped elements mounted for movement in mutually perpendicular directions. Copiers are equipped with inserts attached to the copier elements at their intersections and mounted to move with them 1.

Однако в этих устройствах габариты кареток , на которых установлены элементы, ограничивают настройку копира на минимальный размер, а диапазон установки копира ограничиваетс длиной кареток и линейки . Причем при установке настроенного копира каждый раз необходимо отпускать и зажимать крепежные элементы, на что затрачиваетс много вспомогательного времени , так как если настройка копира на размер производитс один раз, то его установка по числу операций, т.е. по числу вырезаемых отверстий одного размера. Это снижает эксплуатационные качества копира.However, in these devices, the dimensions of the carriages on which the elements are mounted limit the setting of the copier to the minimum size, and the installation range of the copier is limited by the length of the carriages and rulers. Moreover, when installing a customized copier, it is necessary to release and clamp the fasteners each time, which takes a lot of auxiliary time, since if the copier is adjusted for size once, then it is set according to the number of operations, i.e. according to the number of cut holes of the same size. This reduces the performance of the copier.

Кроме того, копир имеет сложную конструкцию , котора не оправдана назнач нием , так как установка копира относительно линейки, а следовательно, и заготовки, в больщинстве случаев не требует высокой точности. Высокой точности требует настройка копира на размер вырезаемого отверсти .In addition, the copier has a complex structure, which is not justified by the appointment, since the installation of the copier relative to the ruler, and hence the workpiece, in most cases does not require high accuracy. High precision requires setting the copier to the size of the hole being cut.

Цель изобретени - повыщение эксплуатационных качеств копира и упрощение его конструкции.The purpose of the invention is to increase the performance of the copier and simplify its design.

Поставленна цель достигаетс тем, что копир снабжен основанием, на котором нанесена координатна установочна сетка, кажда вставка снабжена стойкой, а кажда стойка копира - электромагнитом дл взаимодействи с основанием.The goal is achieved in that the copier is provided with a base on which a coordinate installation grid is applied, each insert is provided with a stand, and each stand of the copier is equipped with an electromagnet for interacting with the base.

Копир снабжен устройством дл выборки зазора между вставкой и г-образным элементом .The copier is equipped with a device for sampling the gap between the insert and the g-shaped element.

Claims

Each electromagnet is provided with a base rectangular plate rigidly attached to it. Each strut is equipped with a rolling support. FIG. 1 shows the proposed copier, a general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one; in fig. 4 shows a section B-B in FIG. ,one. The copier contains movable L-shaped elements 1 and 2 of the copier mounted on racks 3 and 4 with the possibility of movement relative to the base 5 in mutually perpendicular directions, two brown radius inserts 6 and 7 fixed on the elements of the copier at their intersections and mounted with ability to move with them. The inserts, as well as the L-shaped elements, are equipped with racks 8 and 9. The racks 3, 4, .8 and 9 of the optical copier are electromagnets 10-13. Electromagnets interact with the base, which is fastened directly to the Gololu1) tomato. The base is made in the Ic; ic of the K. plate from a ferromagnetic material, the dimensions of which are larger than the dimensions of the contour of the copier, which looses the range of assemblies. On the surface of the plate is applied, for example, by the method of electrochemical etching, the coordinate installation grid 14, which facilitates the installation of a customized copier. Each fitting is carried out with the possibility of extracting the gap in the place of its conjugation with the extrusion using the rollers 15 and 16 of the eccentric screw 17 and screws 18 and 19. The absence of a gap eliminates copywriting and increases the accuracy of the setting. Each insert by pressing fit firmly fixed on the corresponding etoyke. The inserts are fixed relative to the H-shaped elements of the axis and are screwed with screws 20 and 21. Each electromagnet is equipped with a 22 square base plate that is rigidly fixed on its contacting surface, which improves the convenience and accuracy of mounting the copier on the field of the grid of the plate due to the presence of straight, right-angled plates . Each pillar is provided with a roller support 23, which reduces the movement force of the copier relative to the plate, especially for large copier sizes. The gap D between the plate and the contacting surface of the electromagnet is provided by the elastic suspension of the rollers 24 in the axial column 25, or by the deflection of the arm 26 when the electromagnets are turned on. L-shaped elements are supplied with material rulers (not shown). Copier works as follows. Move the elements of the copier, adjust the required contour size on the rulers. Screws 20 and 21 secure the copier components. Set the configured copier to the desired position relative to the base end of the workpiece, using for this purpose the coordinate mounting grid 14 on the plate and the base plates 22. Then turn on the electromagnets 10-13, which fix the copier in the set position. The magnetic roller associated with the plasma torch is brought into interaction with the working circuit of the copier (not shown). Due to the fact that the fixing and unlocking of the copier is carried out almost instantaneously (by turning the electromagnets on and off), the time spent on installing the copier is reduced. This advantage is most noticeable when processing a large number of identical parts, since the copier is adjusted to the size once, and its installation on the plate - by the number of parts. The large dimensions of the plate also contribute to the reduction of time costs, which eliminates the need for frequent table and semi-automatic table movements, the presence of an installation grid of base plates, which increase the installation of the copier. All this increases the performance of the copier, which ultimately improves performance. The invention 1. Composite copier by author.
