Abstract
The utility model relates to a verticality measuring apparatus of barrel elements, which is a specific tool for measuring the verticality of barrel elements according to a rule of minimum assessment error. The utility model comprises a precision flat plate, a hollow upright post and a dial gauge, the hollow upright post and the dial gauge match with the precision flat plate, and the hollow upright post is mainly composed of a rod, a spring, a steel ball, a small column, a small spring and regulating screws. The utility model has the advantages of simple structure, fast operation and accurate measurement result, and the utility model is suitable for the verticality measurement of an end face of a barrel element which is relative to a center line of the inner diameter of the barrel element.
Description
The utility model relates to a kind of specific purpose tool of machining manufacturing, the relevant instrument that the relative center line verticality of socket class part end face is accurately measured of saying so more specifically.
At present, at the vertical survey of parts, usually use wide seat try square or omnipotent angle in the mechanical industry.But, if be used to measure the squareness tolerance of the end face of tube kind part with respect to the internal diameter center line, with regard to some difficulty, can't measure in other words at all, particularly, especially more difficult for the part that need accurately read numerical value.
The purpose of this utility model is the shortcoming that overcomes prior art, provides a kind of simple in structure, measures tube kind part verticality measuring instrument easily.
The purpose of this utility model realizes by following proposal, tube kind part verticality measuring instrument of the present utility model, comprise a precise flat Plate, the hollow column that is associated in the precise flat Plate vertical fixing, the mode of connecting firmly adopts the interference step to cooperate, also have one to apply mechanically the fixing clock gauge of two holding screws on the precise flat Plate, in described hollow column, there is an adjusting to have the bar of tapering part, this bar bottom is provided with a spring, bar top has one to regulate jackscrew, on having on the hollow column body, two arrange elastic steel balls down, what every row was all equidistant is provided with 3, all there are little spring and small column in each steel ball back, steel ball, little spring and small column are close to the tapering part of adjuster bar and by described little spring, are made steel ball be subjected to outside brute force all the time by the compressing of the screw in the screw that screws on hollow column body small column.
The utility model is simple in structure, solved to be used to measure the difficult problem of the end face of tube kind part with respect to the squareness tolerance of internal diameter center line, and measuring instrument of the present utility model, easy to use, measurement result is accurate.
Further describe structure of the present utility model below in conjunction with accompanying drawing, wherein
Diagrammatic cross-section when Fig. 1 is a measuring instrument user mode of the present utility model;
Fig. 2 is the diagrammatic cross-section of the hollow column of the utility model measuring instrument.
Now referring to accompanying drawing, measuring instrument comprises a precise flat Plate 5, the vertical hollow column 6 that connects firmly together with precise flat Plate, and the mode of connecting firmly adopts the interference step to cooperate, as totally shown in Figure 1.In addition, also have one to apply mechanically the clock gauge 4 that two holding screws 3 are fixed on the precise flat Plate, analyse and observe shown in Figure 2 as hollow column, in hollow column, there is an adjusting to have the bar 10 in tapering, one section spring 14 is arranged at this bar bottom, top has one to regulate jackscrew 7, on hollow column body, on having, two arrange elastic steel balls 12 down, every row has three, and all there are little spring 13 and small column 9 in each steel ball back, and is that every cover part is close to adjuster bar by the screw in the screw that screws on the hollow column body 11 compressing small columns and make steel ball be subjected to outside elastic force all the time by little spring 13.
During use, as shown in Figure 1, measured workpiece 1 is inserted hollow column, make the lower surface tightly be close to the precise flat Plate face, wherein the termination 2 of clock gauge 4 is contacted with the end face part of workpiece 1, rotate gently, rotate a week after, then the difference of full-scale reading value on the clock gauge and least count value is part squareness tolerance value.
Claims (2)
1, a kind of tube kind part verticality measuring instrument, it is characterized in that it comprises a precise flat Plate, the hollow column that is associated in the precise flat Plate vertical fixing, also have one to apply mechanically the fixing clock gauge of two trip bolts on the precise flat Plate, in described hollow column, there is an adjusting to have the bar of tapering part, this bar bottom is provided with a spring, bar top has one to regulate jackscrew, on having on the hollow three-dimensional body, two arrange elastic steel balls down, what every row was all equidistant is provided with 3, all there are little spring and small column in each steel ball back, described steel ball, little spring and small column are close to the tapering part of adjustable column by the compressing of the screw in the screw that screws on hollow column body small column.
2, measuring instrument according to claim 1, described precise flat Plate and hollow column are affixed in the mode of interference step partition.
