Detailed Description
In order to make the technical solutions of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.
As shown in the drawings, the detachable measuring head of the 3D edge finder of the present invention includes:
the shell is provided with an installation groove on one surface and used for accommodating components such as a transmission rod, a sphere, a sliding frame and the like;
the measuring head comprises a ball head part and a connecting part, the ball head part is used for contacting the surface of a workpiece, the connecting part is a cylinder made of a material easy to break, one end of the connecting part can be detached from the ball head part of the connecting piece, and the other end of the connecting part is fixedly connected with the transmission rod; the ball head part and the connecting part are connected through threads. The connecting portion are equipped with the screw hole, and bulb portion is equipped with the threaded rod that matches with the screw hole.
One end of the transmission rod is fixedly connected with the measuring head, and the other end of the transmission rod is provided with a groove for embedding the sphere; the transmission rod is internally provided with a screw rod, the nut end of the screw rod is positioned in the groove and is abutted against the ball body, and the measuring head is provided with a threaded hole connected with the other end of the screw rod. The fixing frame and the transmission rod are respectively provided with an annular clamping groove used for installing a rubber protective sleeve. And a sealing ring is arranged between the fixing frame and the mounting groove.
The two opposite ends of the sphere are respectively clamped with the groove of the transmission rod and the clamping groove of the sliding frame;

The fixing frame is fixedly installed at the opening of the installation groove, a through hole through which the transmission rod can penetrate is formed in the fixing frame, an inner spherical surface is arranged on the side wall of the through hole, and the transmission rod is provided with a convex spherical surface abutted to the inner spherical surface.
The working principle of the embodiment is as follows: the spring provides elastic force for restoring the sphere to the original position. The measuring head is stirred to drive the transmission rod to rotate. The transmission rod and the sphere slide, and the spring pushes the sphere and the support rod to keep the measuring head at the shifted angle. And then the measuring head is contacted with the measured plane of the measured object, and the measuring head is moved along the measured plane, when the measured plane jumps, the measuring head can drive the transmission rod to rotate along the sphere, and the transmission rod can output and amplify the movement amount, so that the measuring function of the edge finder is realized. A connecting part made of easily breakable material is arranged between the measuring head and the transmission rod. When the ball head is stressed by a large force, the connecting part can be broken, so that the internal structure of the edge finder is protected, and the edge finder is prevented from being damaged due to failure after being stressed and deformed.
