Description
Technical field
The present invention relates to field of measuring technique more particularly to a kind of clamping of coordinate measuring machine stylus and adjustment mechanisms.
Background technique
Three coordinate measuring machine (Coordinate Measuring Machine, abbreviation CMM) is development the 1960s
A kind of new and effective fine measuring instrument to get up.Its appearance, be on the one hand due to automatic machine tool, numerical control efficient processing and
Originally quickly and effectively detection device is matched for more complicated shape part processing needs；It on the other hand is due to electronics skill
The development of art, computer technology, digital control technology and precision processing technology provides technical foundation for the generation of CMM.
Nineteen sixty, First CMM to late 1960s has nearly ten states to Britain's FERRANTI Developed in the world
More than 30 companies of family are in production CMM, but the CMM in this period is still in the junior stage.Into after the 1980s,
It is constantly put out a new product with Zeiss, Moore etc. for the company of representative, so that the trend pickup of CMM.Modern CMM can not only
Various complicated measurements are completed under the control of the computer, and can realize the control to processing by exchanging information with numerically-controlled machine tool
System.Currently, CMM is widely used to machinery manufacturing industry, auto industry, the departments such as electronics industry, become modern industry detection and
Quality controls indispensable omnipotent measuring device.
For CMM with gauge head come pickoff signals, the performance of gauge head directly affects measurement accuracy and measurement efficiency.It is used on CMM
Gauge head, contact and contactless two class can be divided into.Contactless gauge head is based on light reflection principle, is not required in measurement process
Want stylus, but due to the limitation of focusing range, the range very little in short transverse；The measurement result of contactless gauge head simultaneously
It is affected by measured piece material and surface roughness, use occasion is by larger limitation.Currently, precision highest, uses
Widest in area or contact measuring head.Contact measuring head needs to touch measured piece with stylus.To the reliable, quick of stylus
It is convenient to clamp, it is most important to raising measurement accuracy and measurement efficiency.
In order to improve measurement accuracy and measurement efficiency, clamping measured piece repeatedly is needed to avoid in measurement process as far as possible, most
It is that all features have been measured under clamped one time well.For this purpose, current solution, which has, surveys seat (such as Reinshaw by rotation
PH10M) or use star stylus.Rotation survey seat there are resetting error, measurement accuracy is restricted, be frequently used in compared with
On the measurement demand of low precision.It is all using star stylus in high-acruracy survey demand.The installation of star stylus usually by
Modular component, such as tetragonal body, hexahedron and all directions body.When polyhedron component is installed on stylus frame with screw, due to
Degree difference is tightened, direction has biggish difference.
Traditional stylus clamp system has the stylus clamping device of German leitz company (being subordinate to Hai Kesikang group) (such as
Shown in attached drawing 1), the disadvantages of complicated integral structure, manufacturing cost is high, and service life is short.
