Abstract

The invention discloses a hole measuring tool for a base plate elastic strip. The hole measuring tool comprises a measuring head, a dividing ruler, a fixing bolt, a sleeve and a base, wherein the sleeve is vertically fixed on the base, the dividing ruler is vertically arranged and inserted into the sleeve and can slide vertically in the sleeve, the side wall of the sleeve is provided with throughholes, the fixing bolt is inserted into the through holes and abuts against the dividing ruler, the measuring head is transversely arranged in a cylindrical shape and is perpendicular to the dividingruler, and one end of the measuring head is fixed on the upper portion of the dividing ruler. The hole measuring tool for the base plate elastic strip has the advantage that the measurement of the distance between an elastic strip insertion hole and a rail supporting face is more accurate and convenient.

Description

technical field [0001] The invention relates to a hole measuring tool for double housing, in particular to a hole measuring tool for a spring bar of a backing plate. Background technique [0002] DT series fasteners are one of the commonly used fastener systems in domestic rail transit construction, and the iron backing plate is an important part of the fastener. The iron backing plate is provided with a rail bearing surface for laying steel rails, and an insertion hole for elastic bars for installing elastic bars. The height value from the spring bar insertion hole to the rail bearing surface is related to whether the spring bar can achieve its ideal working state, and is an important dimension for the production inspection of the iron backing plate. At present, this size is usually measured with a height gauge, but since the insertion hole of the spring bar is a deep cylindrical shape, the measurement error with tools such as a height gauge is relatively large.
