Technical Field
The utility model belongs to the technical field of measure, relate to a frock for rapid survey particularly.
Background
A bolt is a widely used fastener, and a bolt with a raised head has various head shapes, such as a hexagon head shape (see fig. 5), a dodecagonal head shape (see fig. 8) and the like, and in use, an under-head supporting surface (a surface connected with a threaded rod of the bolt) by the raised head and a coupling nut which is used cooperatively generate clamping force on an object to be coupled therebetween so that the object to be coupled therebetween are coupled together. The thickness of the bolt head can influence the mechanical properties of tensile force, strain resistance, fatigue resistance and the like which can be borne by the bolt head, so that the thickness of the head needs to be accurately measured in the process of manufacturing the head of the raised head bolt. Because the head of this kind of bolt adopts the upset shaping more, because of the technology needs, can form the not level and uneven arch (burr) at the head outer terminal surface during the upset, it can form the sink with the head outer terminal surface. Due to the existence of the recess, the thickness of the head from the top of the recess to the under head support surface can only be measured by using a common vernier caliper, but the thickness of the head from the bottom of the recess to the under head support surface cannot be measured, and the measurement is the main measurement influencing the mechanical properties of the bolt head, such as tensile force bearing capacity, strain resistance, fatigue resistance and the like. Therefore, when upsetting the bolt head with the raised head shape, the raised part of the recess is firstly turned to expose the bottom plane of the recess, and then the thickness of the head is measured by a vernier caliper. This results in the need to equip a lathe at any time, and is used when special purpose is taken to upset this type of bolt measurement head, has increased the cost. For the bolt with the washer (flange) under the head as shown in fig. 8, when the thickness of the whole bolt head from the outer end face of the head to the support face of the washer (flange) is measured by a micrometer in the subsequent processing procedure of removing the protrusion (burr), that is, when the excessive allowance of the end face of the head is removed, the measurement position of the measuring head of the micrometer is blocked due to the washer (flange), so that the accurate measurement by the micrometer cannot be performed, and the use is inconvenient.
