Description
Technical field
The present invention relates to the measurement of coordinates technical field, relate in particular to a kind of location locking mechanism of replaceable chaining pin.
Background technology
The three dimensional probe, 3-D probe parts that use on coordinate-measuring instruments such as numerical control gear measuring machine often require its chaining pin to change easily.
U.S. Pat 5209131 discloses a kind of mechanism of quick replacing chaining pin, and as shown in Figure 1, three balls 39 are cemented on the chaining pin seat 34 among the figure, and ball 39 engagements on three grooves 58 and the chaining pin seat 34 are arranged on the chaining pin assembly 52, but realizes the accurate resetting of chaining pin.The magnet 38 that is cemented on the chaining pin seat 34 utilizes magnetic force that chaining pin 52 and chaining pin seat are attracted together.When changing chaining pin, overcome the magnetic force of magnet 38, chaining pin 52 can be separated with chaining pin seat 34 with external force.When reinstalling chaining pin, only need the ball 39 on the 58 aligning chaining pin seats 34 of the groove on the chaining pin 52 under the suction of magnet 38, just can be locked at chaining pin on the chaining pin seat.
Detent mechanism of the prior art and latch mechanism respectively be integral, separate, the problem of bringing thus has:
1. three balls and three-flute have been formed fortune merit detent mechanism, realize the location of chaining pin on the chaining pin seat; The magnet that is used for chaining pin is locked on the chaining pin seat is latch mechanism.Because both do not overlap,, make the unreliable contact of surface of contact of detent mechanism is accurately located by chaining pin if coupling mechanism force is too small; If coupling mechanism force is excessive, can destroy locating surface, influence bearing accuracy equally, need very big external force when taking off gauge head simultaneously.
2. when adopting magnetic locking, the distance between magnetic force size and magnet and the ferromagnetic material is nonlinear relationship, and both magnet suction was very little when both distances are far, and along with distance reduces, suction increases rapidly, in case contact suction is very big.Because the foozle of each part of detent mechanism and rigging error exist, the distance of accurately setting magnet on chaining pin and the chaining pin seat is very difficult, often the design of magnet suction there is very big nargin for this reason, causes and take off the external force that gauge head need be very big, can produce impulsive force when gauge head is installed.
3. when gauge head was worked, in case gauge head and workpiece are interfered, an anchor point broke away from engagement, and magnetic attraction reduces rapidly, and gauge head will fall down from measuring head base at once, and chaining pin is damaged.
