Description
Technical field
The utility model belongs to steel tape Calibration Technology field, relates in particular to a kind of for the detachable zero-bit calibrating installation of steel tape verification table.
Background technology
Steel tape can be divided into three kinds by its purposes: a) ordinary steel tape measure is for measuring the length of object, b) depth measurement steel tape is mainly used in measuring liquid depth, c) steel surrounding ruler is mainly used in measuring diameter and the girth of object, in the manufacturing process of steel tape, portraying of scale can exist error, and steel tape range is larger, the error existing is also just larger, particularly range is steel tape more than 5m, the error that scale is portrayed has had influence on the measurement result of steel tape, therefore need to be for the calibrating of steel tape precision, at present the calibrating of steel tape is generally used to steel tape verification table, in steel tape vertification regulation, stipulate, to depth measurement steel tape except carrying out steel tape precision verification, also need to carry out zero-bit calibrating, " error of zero " refers to the error to 500mm place groove by depth measurement steel tape chi stone roller end face (being the end at zero point of chi), because depth measurement steel tape chi stone roller is connected with blade, tend to introduce this error, depth measurement steel tape " error of zero " must not be greater than 0.5mm, therefore depth measurement steel tape calibrating, first should carry out zero-bit calibrating, adopt special verification table or the employing two step checking methods with zero-bit calibrating portion for the calibrating of depth measurement steel tape at present, it is high that the former examines and determine cost, the latter can not disposablely complete testing, on two equipment, detect and introduce certain secondary positioning error, be not easy to the examination of whole detection precision.
Summary of the invention
In order to solve the problems of the technologies described above, it is a kind of for the detachable zero-bit calibrating installation of steel tape verification table that the utility model provides, comprise main body, V-type frame, characterized by further comprising zero-bit regulating device, mounting and positioning device, described zero-bit regulating device is arranged on one end of described main body, comprise location support plate, zero adjusting screw, lock-screw, described location support plate is fixedly connected with described main body; Described zero adjusting screw runs through the center of described location support plate; Described lock-screw is arranged on the side of described location support plate; Described mounting and positioning device is arranged on the other end of described main body, comprises groove, installation reference column, trip bolt, gib screw are installed; Described installation groove connects described main body, and middle part is provided with trip bolt; Described installation reference column is arranged on the upper surface of described main body, and top bends downwards, forms holding section; Described installation reference column is fixedly connected with described main body; Described gib screw is threaded with holding section; Described V-type frame is arranged on the middle part of described main body, removably connects with described main body.
