Embodiment Construction

[0018] The present invention consists of a ruler body 1, a digital display indicator 2, a vernier seat 3, a fixed block 4, a bar clamp 5, and a U-shaped calibration block 10.

[0019] figure 1 It shows that there is a long hole in the center of the vernier seat 3, and the long hole matches the cross-sectional shape of the ruler body 1. The vernier seat 3 is set on the ruler body 1 through the long hole, and the vernier seat 3 and the ruler body 1 are a sliding fit. , there is a vernier seat locking bolt 8 above the vernier seat 3 to fix the vernier seat 3 with the ruler body 1 . A spacer is provided between the vernier seat 3 and the ruler body 1 to ensure the flexible sliding of the vernier seat 3, and the ruler body 1 is marked with centimeter scales.

[0020] figure 1 Display, the digital display dial indicator 2 is installed and connected with the vernier seat 3, and the digital display dial indicator 2 is made up of the dial indicator head, the measuring pin 11, and the...

Abstract

The invention relates to a bar bending degree measuring instrument, belongs to the technical field of metallurgical bar measuring tools, and is used for measuring the bending degree of a metal bar. The bar bending degree measuring instrument is characterized in that a vernier seat is in sliding fit with a vernier body, a digital display dial indicator is fixedly mounted at the lower part of the vernier seat, two fixing blocks are respectively mounted at the two ends of the vernier body and in sliding fit with the vernier body, the upper parts of two bar cards are in assembly connection with the fixing blocks, and V-shaped clamping grooves are formed in the lower parts of the two bar cards. The fixing blocks at the two ends of the vernier body are in positioning contact with a bar, the digital display dial indicator in the middle of the vernier body is used for performing distance measurement on the surface of the bar, the bending degree detection precision can satisfy the bending degree of 0.1 mm per meter, and the bending direction of a steel product can be displayed. The bar bending degree measuring instrument provided by the invention is simple in structure and accurate in measurement, and can be operated by a single person; the bending degree of the bar between 200-1000 mm can be measured through moving of the fixing blocks and the bar cards; the bending degrees of other plates and pipes can also be measured.

Description

technical field [0001] The invention relates to an instrument for measuring the curvature of metal rods, belonging to the technical field of metallurgical rod measuring tools. Background technique [0002] Bars produced in the metallurgical industry have certain requirements for bending in national standards or industry standards. The general measurement method is to use a 1000mm board ruler to close the measured long product, and use a feeler gauge at the gap between the measured long product and the board ruler. Or measure with a depth gauge with a vernier caliper, and the resulting size is the curvature per meter. The general measurement method requires two people and two tools to use together, and the bending value cannot be directly obtained. Therefore, a practical and convenient tool for measuring the bending degree of the bar is needed. Contents of the invention [0003] The technical problem to be solved in the present invention is to provide a bar bending degree ...
