Flat-bulb steel ball head measuring tool and method for measuring thickness of ball head by using same

Abstract

The invention discloses a flat-bulb steel ball head measuring tool which comprises a plurality of measuring calipers, arc grooves matched with ball heads of flat-bulb steel of different sizes are formed in the measuring calipers, hanging holes are formed in the ends, away from the arc grooves, of the measuring calipers, and the measuring calipers are connected with hanging rings through the hanging holes. And each measuring caliper is provided with an identification layer for marking and measuring the ball end fillet radius of the flat-bulb steel ball. The bulb measuring tool is adopted to inspect the bulb of the flat-bulb steel, the phenomenon that the thickness of the bulb does not meet the standard requirement is avoided, the inspection means are increased, and the quality risk of the flat-bulb steel is effectively reduced; and the measuring tool is made of stainless steel plates of 1 mm, each tool is provided with holes of 4 mm, a whole set of 17 tools are connected in series, and the measuring tool is convenient to carry and operate. The thickness of the ball head is directly measured on the basis of original measurement, and stable and controllable quality of the ball head is ensured.

Description

technical field [0001] The invention relates to a measuring tool for a spherical flat steel ball head and a method for measuring the thickness of the ball head using the same. Background technique [0002] When the flat bulbs are put into storage, the length and width of the flat bulbs are routinely measured with a tape measure, and the height of the flat bulbs is measured with a vernier caliper. The radius of the rounded corner of the ball end cannot be measured, and the thickness of the ball head cannot be controlled. There is a certain quality risk. Previously, the applicant had two ball heads that were inconsistent in size during on-site butt jointing, which could not meet the welding requirements. Some shipowners clearly require the measurement of the bulb flat steel ball head. Contents of the invention [0003] The purpose of the present invention is to overcome the defects existing in the prior art and provide a flat steel ball head measuring tool, which can be use...

[0002] When the steel bulbs are put into storage, the length and width of the steel bulbs are routinely measured with a tape measure, and the height of the steel bulbs is measured with a vernier caliper. The radius of the ball end fillet cannot be measured, and the thickness of the ball head cannot be controlled. There is a certain quality risk.

Previously, the applicant had two ball heads that were inconsistent in size during the on-site butt joint, which could not meet the welding requirements.
