Embodiment Construction

[0022] see figure 1 , which shows a portion of a machine tool 200 having a spindle 210 driven directly by a motor 220 . A cavity or shank receiving area in the form of a conical housing 230 in the spindle 210 is used to hold a tool or, as shown in this figure, a measuring probe 100 . Modern machine tools have automatic tool changers. Instead of the knife, other auxiliary devices can also be used. All devices will mount to a standard tool handle 360. Most standard tool shanks are of a tapered (truncated cone) configuration. Using this invention, it is possible to use a carousel of cutters together with one or more auxiliary devices and have the program select the correct tool / assistant device. When a measuring operation is to be performed, the auxiliary device in the form of a measuring probe is selected from the carousel and fitted automatically into the spindle. The machine can be moved to the desired position and the workpiece can be measured either by translational mov...

Abstract

The invention relates to the transmission of power and / or data from / to a stationary part of a machine tool 200 to / from an accessory 100 mounted in the spindle 210 of the machine tool 200. A first electrical link or interface 1a, 1b, 1c, 1d provides electrical communication between the stationary part 200 and the spindle 210, and a second electrical link or interface 3 is provided electrically connected to the first electrical link at the accessory mounting area 230. The second link 3 is in the form of electrical contacts. The invention extends to an accessory shank 360 for mounting to the spindle 210 of the machine tool, and also to an accessory 100 e.g. in the form of a measurement probe, connected to the said shank 360.

Description

technical field [0001] The present invention relates to the transmission of electricity and / or data within a machine, such as a machine tool, and in particular, but not exclusively, to means for powering and data communicating with electrical auxiliary devices, such as measuring probes mounted on the machine spindle. Background technique [0002] When an electrical auxiliary device such as a measuring probe is located in the machine tool spindle typically used for the tool, it is difficult to supply power to the auxiliary device and provide signal paths to and / or from the auxiliary device. Batteries have a limited lifespan, especially when large amounts of probe data are wirelessly transmitted to remote receivers. It is also not desirable to assemble additional power supply or data transmission components around the spindle of the machine, since these components could interfere with tools subsequently set in the spindle, or these components could collide with the workpiece o...
