Clamping plate (2) is provided with orientation elements (6, 7), at least two center elements (5 »11) and clamping means (gj, v clamping means) at least one aperture is formed in the plate (2) (9) in which the reference tyS is inserted (10).

Description

BACKGROUND OF THE INVENTION The present invention relates to an alignment and clamping device for electro-sparking machines, in particular for fusing and clamping workpieces, of at least two, in electrolocker machines with automatic tool and workpiece change.

The current trend in the development of electrocross machines is focused on maximizing the efficiency of the machining process. The equipment of the control ayatams controlled by the computers has also made the handling materials necessary for the control of the automatic elements during the setting, clamping of tools and workpieces as efficient as possible. The present technique is realized in new generation electro-gravel machines and automatic change of tools and workpieces, where individual working tools and workpieces stored in cartridges are automatically manipulated into the machining process and after the operations are replaced by others. So far, the workpiece milling and the clamping operation have been carried out on the work-atoll individually, so that the workpiece is first oriented in the x and y asses against the atoll eyes, and then the clamping and position control has been performed. Furthermore, aa guided the quill and the working tool by manual control over the workpiece. The difficulty of the operation is particularly great when it is necessary to set up and clamp more workpieces.

These setbacks are alleviated and the technical problem of the setting and clamping device for electro-sparking machines consists of a clamping atoll on which the clamping clamp is fixed, the clamping clamp being provided with orientation elements, at least two middle elements and clamping means, which in the clamping plate at least one opening is formed in which the reference rod is inserted. The position of the reference rod is dimensionally ¹ defined in the x, y axes relative to the center and the elements.

Advantage of the setting and clamping device for the electro-sparking machines according to the invention is that it is possible to set up and clamp up to 8 workpieces on which the electroacoustic machining operations will be performed in the required spacing in the axes x and y. work tool reference.

An alignment and clamping device for electro-spark machines is shown by way of example in the accompanying drawing, in which: FIG. 1 is a partial cross-sectional view of the attachment and clamping device, and FIG. 2 is a bottom plan view of the positioning and clamping device.

The clamping device for the electro-sparking machines consists of a clamping shaft 2 and a clamping plate Z. The clamping plate Z is clamped on the clamping table 1 by means of screws 4 located at the end of the clamping plate. , e.g., on Wednesday upínaoaj Doak AA ^r · receiving a reference bar 2 £ and V of the clamping Doak F · ύ is detachable fixed guide elements and, from and stored for at least two atrediáoe elements 2, H · Area orientačnýoh elements £, from a strediecioh elements 2, 11 j · depends on the shape and number of workpieces Z.

Function ustavovaeieho a clamping device for spark etroje of the invention is neeledovná: Atoll and elektrolskróvého the machine is centered upínaoia Doak Z · ^The clamping plate 2 and on the intended rozstupooh stored workpieces 2, through means of alignment and atrediaoieh elements 2 »11 oriented in osiaoh x and y with the aid of the orientation elements 2, the locking means a is carried out by means of clamping means g, for example screws with a nut and a washer. An electro-jet engine and an automatic tool change equipped with a tool position programming system in o and aoh x, y, z will move the tool there and measure the position of the reference bar 10 as the starting reference. The tool is moved from the reference position by a system-controlled mechanism in accordance with the programmed values, which are dimensionally identical to the workpiece spacing 2. Electrolytic machining operations are then carried out on each workpiece.

Claims (1)
