Problems solved by technology

[0002] Conventional digital display micrometer, because the shape of the end of the measuring anvil and the moving micrometer screw is fixed, the moving range of the moving micrometer screw is limited, and it cannot be detected for some special positions, such as the measurement of the diameter of a larger diameter reamer, with a groove Or the detection of the wall thickness of the groove of the arc surface component or the arc surface, etc. For example, when the reamer blade is long, the maximum point of the diameter of the knife may not be on a horizontal line. The maximum diameter of the diameter; if a dedicated digital micrometer is equipped for each detection situation, it will increase the manufacturing cost

Embodiment Construction

[0016] Multifunctional digital display micrometer, including digital display micrometer, is characterized in that a measuring head is installed on the measuring anvil and / or moving micrometer screw rod of the digital display micrometer, and one end of the measuring head is made to cooperate with the measuring anvil and the moving micrometer screw rod. , Install the magnetic sheet in the inner hole.

[0017] The measuring head is composed of a cone section and a cylinder section, an inner hole is made in the cylinder section, a magnetic sheet is installed in the inner hole, and a sphere is made at the tip of the cone section.

[0018] The measuring head is composed of cylindrical sections at both ends and a cone section in the middle. The cylindrical section connected to the large-diameter end of the cone section is made with an inner hole, and a magnetic sheet is installed in the inner hole. The cylindrical section connected to the small-diameter end of the cone section The en...

Abstract

The invention discloses a multifunctional digital micrometer, which is used for measuring the diameter dimension of a reamer with larger diameter and the thickness of a groove or an arc surface wall with a groove or an arc surface component in the machinery machining industry. The multifunctional digital micrometer comprises a digital micrometer, and is characterized in that a measuring anvil and / or a moving micrometric screw rod of the digital micrometer is provided with a measuring head, inner holes matched with the measuring anvil and the moving micrometric screw rod are made on one end of the measuring head, and magnetic sheets are mounted in the inner holes. The invention has advantages that the measuring head is designed aiming to measure the diameter dimension of the reamer with larger diameter and the thickness of the groove or the arc surface wall with the groove or the arc surface component, is installed on the measuring anvil and / or the moving micrometric screw rod to measure the reamer with the larger diameter, the groove or the arc surface and is matched according to a demand, thereby increasing functions of the digital micrometer; and the cost of matching the measuring head is less than that of matching a special digital micrometer.

Description

Technical field: [0001] The invention is used for the measurement of the diameter of the larger-diameter reamer used in the mechanical processing industry, and the detection of the wall thickness of the groove or the arc surface of the member with the groove or the arc surface. Background technique: [0002] Conventional digital display micrometer, because the shape of the end of the measuring anvil and the moving micrometer screw is fixed, the moving range of the moving micrometer screw is limited, and it cannot be detected for some special positions, such as the measurement of the diameter of a larger diameter reamer, with a groove Or the detection of the wall thickness of the groove of the arc surface component or the arc surface, etc. For example, when the reamer blade is long, the maximum point of the diameter of the knife may not be on a horizontal line. The maximum diameter of the micrometer; if a dedicated digital micrometer is equipped for each detection situation, ...
