Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
195 words
A measuring apparatus for measuring dimensions of workpieces comprising: a frame; connecting means; a support carried by the frame through said connecting means which permit movements of the support relative to the frame; a measuring head mounted on the support and comprising a measuring arm adapted to cooperate with the workpiece to be measured and movable in the head toward and away from the workpiece; detecting means mounted in the head for measuring the position of the arm in the head; said connecting means permitting movement of said support together with said measuring head toward and away from the workpiece; first mechanical reference means fixed on said support and second mechanical reference means fixed on said frame adapted to cooperate with said first mechanical reference means for displacing said support together with said head in a defined position for the measurement of workpieces having a determined nominal dimension, this position corresponding to the head zerosetting; at least one of said first and second mechanical reference means being replaceable by similar reference means having a different determined dimension for achieving automatically the zero-setting of the measuring head, when measuring workpieces having a different determined nominal dimension.
Claim 2
Dependent Claim
195 words
A measuring apparatus for measuring dimensions of workpieces comprising: a frame; connecting means; a support carried by the frame through said connecting means which permit movements of the support relative to the frame; a measuring head mounted on the support and comprising a measuring arm adapted to cooperate with the workpiece to be measured and movable in the head toward and away from the workpiece; detecting means mounted in the head for measuring the position of the arm in the head; said connecting means permitting movement of said support together with said measuring head toward and away from the workpiece; first mechanical reference means fixed on said support and second mechanical reference means fixed on said frame adapted to cooperate with said first mechanical reference means for displacing said support together with said head in a defined position for the measurement of workpieces having a determined nominal dimension, this position corresponding to the head zerosetting; at least one of said first and second mechanical reference means being replaceable by similar reference means having a different determined dimension for achieving automatically the zero-setting of the measuring head, when measuring workpieces having a different determined nominal dimension.
Claim 3
Dependent Claim
27 words
The measuring apparatus according to claim 1, wherein said connecting means comprises pivot means permitting pivotal movements of said support and measuring head relative to said frame.
Claim 4
Dependent Claim
33 words
The measuring apparatus according to claim 1, wherein said first mechanical reference means comprises a contact point adjustably fixed on said support, said point being adapted to contact said second mechanical reference means.
Claim 5
Dependent Claim
54 words
The measuring appearatus according to claim 1, wherein said second mechanical reference means comprises a block of a determined thickness adapted to cooperate with said first mechanical reference means, and replaceable by similar second mechanical reference means having a block of determined different thickness for achieving automatically a new zero-setting of the measuring head.
Claim 6
Dependent Claim
42 words
The measuring apparatus according to claim 1, wherein said second mechanical reference means is replaceably fixed on said frame, and comprises a member defining a seat for positioning the workpieces having a determined nominal dimension in a determined position on the frame.
Claim 7
Dependent Claim
28 words
The apparatus according to claim 5, wherein said member defines holes in said seat for the passage of a feeler mounted at one end of said measuring arm.
Claim 8
Dependent Claim
46 words
The measuring apparatus according to claim 5, wherein on said member there is fixed a block of determined thickness and adapted to cooperate with said first mechanical reference means for achieving automatically the zero-setting of the measuring head when measuring workpieces having a determined nominal dimension.
