Device for measurement of machine tools
At least two identical combined transmitter/receivers are used to perform a measurement task to be carried out. Each combined transmitter/receiver utilizes a combined exit/entrance window. The identical configuration of the transmitter/receiver yields major cost advantages in the production of these articles.
1. Device for measuring machine tools, comprising
a housing with at least one exit/entrance window which enable light beams to pass in and out of the housing,
a power supply,
a clamping cylinder or pin on said housing for securing the housing on a machine tool,
a light beam transmitter for producing a light beam,
a beam splitter in said housing, and
an optoelectronic target in said housing, said target having a two-dimensional read-outs,
wherein said at one exit window comprises first and second exit/entrance windows, each of which is at a different side of said beam splitter from each other and said light beam transmitter, wherein the first and second exit/entrance windows are located at sides of the housing which are at right angles relative to each other.
2. Device as claimed in claim 1 , wherein said windows are filter windows and are matched to the wavelength of light emitted by said light beam transmitter.
3. Device as claimed in claim 2 , wherein said light beam transmitter is a laser.
4. A system for measuring machine tools, comprising:
a first transmitter/receiver having a housing that is mountable on a first machine tool;
a second transmitter/receiver, identical to said first transmitter/receiver, that is mountable on a second machine tool, and
a third transmitter/receiver, identical to said first transmitter/receiver, that is mountable on a third machine tool
wherein each said transmitter/receiver is operable for transmitting a light beam to at least one other of the transmitter/receivers and for receiving a light beam from at least one other of the transmitter/receivers for performing alignment measurements of said machine tools based on the positional relationship of the impact points of the light beams in each transmitter/receiver.
5. A system for measuring machine tools according to claim 4 , wherein each transmitter/receiver comprises:
a housing wit two combined exit/entrance windows which enable light beams to pass in and out of the housing,
a light beam transmitter for producing a light beam,
a beam splitter in said housing, and
an optoelectronic target in said housing, said target having a two-dimensional read-out,
wherein each of said combined exit/entrance windows is at a different side of said beam splitter from each other and said light beam transmitter.
6. A method for measuring alignment of machine tools, comprising:
sending a first beam from a first transmitter/receiver located on a first machine tool to a second transmitter/receiver located on a second machine tool and to a target on the first machine tool;
sending a second beam from said second transmitter/receiver to said first transmitter/receiver and to a target on the second machine tool;
sending a third beam from a third transmitter/receiver to said second transmitter/receiver and to a target on the third machine tool;
obtaining deviations of impact points of said first, second and third beams from the target located in each of the first, second and third transmitter receivers; and
using the deviations obtained for determining an offset of spindles of the machine tools.
7. Device as claimed in claim 5 , wherein the first and second exit/entrance windows are located at sides of the housing which are at right angles relative to each other.
