DD225089A1 - DEVICE FOR ADJUSTING TRANSLATORED WORK TOOLS - Google Patents

Abstract

The invention relates to a device for the unilateral adjustment of transposed, fast-wrenching working tools, for example separating discs for the separation of embedded concrete rods. OBJECT OF THE INVENTION IS TO DEVELOP A DEVICE WHICH DETECTS THE WEARING OF THE WORK TOOL AND TO IMPLEMENT IT IN A POSITION. According to the invention, a tool carrier is moveable on a portals and a sensory carrier is fixed. THE TOOL CARRIER HAS A WORK TOOL AND ADJUSTING UNITS EQUIPPED WITH WAY MEASURING EQUIPMENT. SENSOR TRAVERS, ADJUSTING UNITS AND ROUTE MEASURING EQUIPMENT ARE CONNECTED TO A MICRORECHNER. THE SENSOR CARRIER FEATURES AN OPTICAL SENSOR WHICH CAPTURES THE EXTERNAL DIAMETER OF THE WORK TOOL.

Description

Title of the invention

Device for specializing translationally guided work tools

Field of application of the invention

The invention relates to a device for uniaxial Uachstellen translatorisch led, fast-wearing work tools in which the wear is compensated automatically, especially for the separation of cast-in concrete steels when re-clamping prestressed concrete elements by means of cutting disc.

Characteristic of the known state of the art

In DE-AS 2340535 a device for automatically detecting and compensating the tool wear on a cut-off machine is already described. This device is used to edit large workpieces with two mutually staggered cut-off wheels. For detecting and compensating the tool wear a scanning device and a feed gear is provided, whose movements are controlled by the scanning v / earth. The outer diameter of the cut-off wheels is constantly ^: detected by a respective associated scanning devices. Working with two cutting wheels requires more effort and is often not necessary. Further part of the shell is that the compensation of the wear requires sliding contacts with corresponding comparator and correction circuits and for the implementation of the movement

gearboxes must be used with driven lead screws.

Object of the invention

The object of the invention is to automate the process-related Uachstellarbeiten in cutting, grinding or the like., And to increase the accuracy of the cut.

Explanation of the essence of the invention

The object of the invention is to develop a device with which the wear of the working tool in its direction of movement is detected and the deviation of the outer dimension is converted into a Hachsteilbewegung, with the necessary for the separation of the prestressing steel facilities, as required for automated systems, with to be used for this.

According to the invention a -Werkzeugträger are on a portal movable and a sensor carrier fixed, wherein the tool support a work tool and for its _horizontal: in each case an adjusting unit carries and 'vertical movement 3 which are provided with path-measuring devices and the sensor support, the ball units and the 'way-measuring devices to a digitally operating evaluation, z. B. microcomputer, are connected. The sensor carrier carries an optical sensor, which detects the outer diameter of the Arbeitswerkzeu-.ges during movement of the tool carrier in working position. , -

Aüsführungsbeispiel

The invention will be explained in more detail below with reference to an embodiment. In the drawing, the device is shown in principle.

The device has the portal 1, on which the tool carrier 2 and the sensor carrier 3 are attached. The tool carrier 2 is moved by means of the adjusting unit for the y-coordinate 5 in the direction of the y-coordinate on the portal 1. Also attached to the portal 1 and with this rigidly

he is wearing the working tool 4, which is a per se known cutting disc. By the adjusting unit for the z-coordinate 6, the working tool 4 is movable in the direction of the z-coordinate. The actuating units 5, 6 are connected to the path measuring devices for the y and z coordinates 7, 8, z, b, incremental encoders and, together with the sensor carrier 3, are connected to the digitally operating evaluation electronics 9, e.g. B. microcomputer, angeloasen.

In the Aua electronics 9, the incoming data is processed according to predefined Algorithmua. The calculated data are transmitted via commands through the path measuring device 7; 8 implemented in readjustments. This ensures that a correction of the work tool 4 is carried out according to the wear, ao that a constant separation der.Spannstähle is guaranteed. In its initial position, the tool holder 2 is in a fixed position of the y and. z-coordinate. During the movement of the tool carrier 2 into the working position in the y-coordinate, the respectively present outside diameter of the cutting wheel or the like is detected, and during the subsequent movement into the working position in the z-coordinate, this determined value is used for the correction of the positioning and thus determines the necessary ITachstellbewegung.
