Novel portable measuring head structure

Abstract

The invention discloses a novel portable measuring head structure, and relates to the technical field of detection equipment. The novel portable measuring head structure comprises an upper main body;a clamping mechanism is fixedly connected to the top of the upper main body; a perspective cover is fixedly connected to the bottom of the upper main body; a connecting piece is fixedly connected to the bottom of the perspective cover; the middle of the connecting piece is fixedly sleeved with a lower main body; the bottom of the connecting piece is fixedly connected with a connecting piece; the bottom of the connecting piece is movably sleeved with a tripod; and a clamping block is movably installed on the outer wall of the tripod. A measuring rod deflection limiting mechanism can effectivelyprevent excessive deflection of a measuring rod, so that the risks that a measuring switch is damaged due to excessive deflection of the measuring rod and the measuring rod is thrown away due to excessive deflection during rotation are avoided, the rotation detection precision is higher, errors caused by decentration of the measuring rod and a main shaft can be eliminated, the detection precisionis higher, coordinates can be detected in a non-rotation state, and the precision is not reduced compared with that in the prior art.

Description

technical field [0001] The invention relates to the technical field of detection equipment, in particular to a novel portable measuring head structure. Background technique [0002] The centering rod structure of the prior art is two cylinders of the same size, and a spring is installed in the center of the two cylinders to make the end faces of the two cylinders fit together. When in use, the centering rod is clamped in Rotate on the main shaft, touch the workpiece that needs to be centered with the side of one end of the cylinder while rotating, and determine the coordinates by observing the concentricity of the two cylinders. The coordinates are determined by visual inspection, and the accuracy of the centering is not accurate. High, the actual use can generally reach 0.02mm precision, which cannot meet the use requirements for high-precision manufacturing. [0003] For this reason, the present invention introduces a new type of portable measuring head structure. The new...

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the present invention provides a new type of portable measuring head structure, which can rotate the measuring head for detection when equipped with a new structure detection, so as to achieve higher detection accuracy. The operation is easy to cause excessive deflection of the probe, or the safety risk caused by excessive rotation speed of the probe. A limit structure is designed for the deflection mechanism of the probe switch to prevent excessive deflection of the measuring rod, avoid safety risks, or damage the probe due to excessive deflection. The electronic circuit can be a potted electronic circuit fixed structure. There is no ordinary electronic circuit structure with solid sealing. The focus is on the advantages of the limit mechanism to prevent the excessive deflection of the measuring rod. It solves the problem that the existing structure is based on the measuring head. The automatic measuring head for machine tool communication needs complex program control and use. The simple manual measuring head has no protection mechanism, and the risk of the measuring rod being thrown away is easy to occur when rotating, and there are certain safety hazards in the operation process.
