Abstract
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.
Claims7
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.
4 more elements
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.
1 more element
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.
