Abstract

A multiple coordinate feeler apparatus, comprising a housing, a feeler arm axially projecting beyond the housing, the feeler arm having a feeler ball formed at the free end thereof and being axially displaceably supported in the housing and being supported at the housing universally rotatable up to a predetermined maximum angle by a spherical joint of a ring seat formed in a housing plate and of a spherical joint head formed at the feeler arm and rotatably supported on the ring seat, a slide being supported by the spherical joint head and being slidable in the housing against the force of a return spring, the slide being coupled with an indicating means indicating the sliding quantity of the slide, the joint head being liftable out of the ring seat by the axial displacement of the feeler arm. For stabilizing the joint head in its ring seat the joint head is formed as a spherical segment, on which a tilting disk is formed which is tiltably axially supported by its circular peripheral edge at the slide, the tilting disk projecting radially beyond the joint head.

Dependent claims

A multiple coordinate feeler apparatus, comprising:

a housing;
a housing plate disposed on said housing;
a ring seat disposed in the housing plate;
a spherical joint head formed of a spherical segment and rotatably supported on the ring seat such that the ring seat and spherical joint head form a spherical joint, the spherical joint head being liftable out of the ring seat;
a tilting disk formed on said spherical segment and projecting radially beyond the spherical joint head;
a feeler arm axially projecting beyond the housing and being supported by said spherical joint and by said spherical joint head such that said feeler arm is axially displaceably supported in the housing and is universally rotatable up to a predetermined maximum angle, said feeler arm being disposed in said spherical joint and spherical joint head such that axial displacement of the feeler arm lifts the spherical joint head out of the ring seat;
a feeler ball formed at the free end of said feeler arm;
a slide supported by said tilting disk and disposed to slide axially in the housing against the force of a return spring in response to either axial displacement of the feeler arm or rotation of the spherical joint;
and
indicating means coupled to said slide for indicating the sliding quantity of said slide.
