Abstract

The subject of the solution is a modular clamping system, where the material composition, physical arrangement and spatial distribution of the system elements are addressed. Its essence is that at least one element of the modular system is made of amorphous material. The elements of the modular clamping system are part of one common semi-finished product, while their shape and dimensions are always adapted to a specific object. The composition of individual elements into an assembly for a specific clamping is simple and the path of the working tool relative to the workpiece is easily accepted. The solution finds application mainly in technological workplaces, where small forces and their moments are introduced into the object, such as in laser, electrochemical machining, or rapid positioning of objects with complex shapes.

Description

265519 2

The object of the invention is a modular clamping system, where the material composition, body arrangement and spatial distribution of the system elements are solved. In the hitherto known modular clamping systems, the kit elements are divided by clamping, positioning, pressing, delimiting, joining and the like, and are produced by any one-off machining to their specific shape and dimension according to a function that is unchangeable. 7, because of the wider use of the clamping system due to the shape and dimensional diversity, the number of elements of the modular clamping system multiplies. This increases storage and maintenance requirements. Setting up and clamping the workpiece on the base plate with these elements is complicated and laborious. In addition, automating this process is difficult if not impossible. There are solutions where one element of the modular clamping system is designed to perform more functions, thereby reducing the number of elements, but making them more complicated and more expensive. In addition, the life of these elements, both material and functional, is less likely to cause failure rates, especially for mechanized elements. Therefore, the modular fixture has to be supplemented with new elements for worn out that go into scrap. Since virtually all of the clamping system elements are made of steel due to the physico-mechanical properties of the material, inaccuracies in the machining process are created, ultimately limiting the achievable manufacturing accuracy, deploying economical overhead conditions, and utilizing the machine's performance to a greater degree, and requiring more demanding positioning machining and machining. further control of the machining process. This demand is currently in full automated technology workplaces. Quickly positioning complex shapes, for example, by acting on them with small external forces such as laser beams. electrochemical! machining, is difficult with current clamping systems.

The above-mentioned disadvantages are alleviated by the modular clamping system according to the invention, the principle of which is that at least one element of the clamping system is made of amorphous material. The elements of the clamping system form part of one common workpiece, each of which has a shape and dimensions adapted to a particular object.

The composition of the individual elements in the assembly for a particular clamping is simple and easily accepts the work tool path relative to the workpiece.

The modular clamping assembly of the present invention makes it possible to form, from a common blank, individual elementary elements, such as spherical shapes, from which any element can be formed according to the desired function, size and shape utilizing some of the physical properties of the amorphous material such as adhesion, extensibility, cure, static and dynamic response. loads, thermal and electrical properties, physical field reactions, for example, heat, electromagnetic, and the like. Positioning, clamping and loosening of objects and rugged, simple, while the individual elements are easily storable, as I can merge into one unit and the original semi-finished product, for example, a simple geometric figure of a cat with small space requirements. The functional properties of the individual elements can already be in the phase of the semi-finished product from which they are produced, distinguished by color or easily identifiable physico-chemical properties.

The use of amorphous materials for the elements of the modular clamping system creates conditions for waste-free technology of their production and reduces material and energy demands.As the properties of amorphous materials are the same in different directions, the elements retain their functional properties even at any deformation. The modular clamping system is the most suitable for "powerless" machining of objects, especially complex shapes, such as laser, electrochemical, etc., when the use of classical modular clamping systems is time consuming due to the use of complicated compositions of individual elements.

An example of the embodiment of the constructional clamping system according to the invention is shown in Fig. 1 on the attached ducts in a partial side view of the clamped object, and Fig. 2 is a schematic illustration of an example of a cycle of constituent clamping system elements. 3 265519

The modular clamping assembly 100 of the present invention consists of a co-product 110 of amorphous material 130. According to the physico-mechanical and geometrical properties of the clamped article 140, and according to the nature of the process, amorphous material 130 which is most suitable for its properties is determined.

Elementary building elements 111, such as moldings, are separated from the common blank 110 to form individual elements 120 of the building fixture 100 as well as its foundation block 125. The making of individual elements 120 from elementary building elements 111 can be accomplished by any known technological process that can be applied for the determined amorphous material 130, for example by blending, pressing, casting, curing and the like. In this way, a clamping element 121, a positioning element 122, a pressing element 123, a connecting element 124 or a foundation plate 125 can be obtained from the elementary structural element 111. In such amorphous materials 130, which can be joined by blending, pressing, gripping and the like, the connecting elements can be omitted. Since their function is the property of the amorphous material 130 itself, such as thermo-plastic, pitch, rubbers, organic glasses such as plexiglass, etc., it can be attracted, while the energy intensity is far less than that of steels. It appears advantageous to use a plurality of common blanks 110, the material of which differs in its properties and to select the amorphous material 130 which, by virtue of its properties, enhances the ability of the element 120 to form the individual elements of the modular clamping assembly 100. For example, the clamping element 121 is preferably made with an expansive temperature. or the shrinking amorphous material 130, for example a polymer-metal glass base, while the positioning element 122 is suitable to be made of a more stable, amorphous material 130t such as glass.

Fig. 2 schematically illustrates an example of reshaping a common blank 110 from amorphous material 130. Elementary building elements 111 are separated from the common blank 110, which illustrates the direction of movement "b" as well as the base plate 125. which we want to fix. From the elementary building elements 111, we form the positioning elements 122 which are arranged on the base plate 125 and reinforced with, for example, adhesion forces in the contact planes. On the positioning elements 122, the pressing elements 123 and the clamping elements 121 can be arranged, whereby, for example, the adhesion forces in the contact planes also ensure their connection and reinforcement. In the case where we machine a laser cutting tool with very little force input into a machined "A" shaped article, this method of joining is sufficient. The direction of movement " b " is characterized by the elementary building elements 111 as well as the foundation plate 125 as separable from the common blank 110 but also integrally integrable therein. The direction of movement " a " in turn characterizes the formation of the clamping elements 121, the positioning elements 122, the pressing elements 123 of the elementary building elements 111, but opposite. If we want to clamp another " B " article 142 where other clamping elements 121 are required, the pressing elements 123 and the positioning elements 122 can be processed by the elementary building elements 111 and therefrom to form a virtually new building fixture assembly 100 special for B-shaped item 142.
