Abstract
The invention relates to a perpendicularity measurement tool. An upper end face of a base plate is fixedly connected with two angle bases. A V-shaped block is arranged between the two angle bases, which are provided with a handle and a dial indicator, respectively. A side end of the dial indicator goes through the side end face of the angle base. A spring is disposed between the handle and the angle base and is located from the side end face of the angle base to a clamping end of the handle. An operation end of the dial indicator and the clamping end of the handle both face the V-shaped block. During perpendicularity measurement, it should be guaranteed that the perpendicularity of two end faces of a piston part relative to an outer circumferential axis of the part is smaller than or equal to 0.05 mm. By means of the tool, a perpendicularity value detected is converted to a jerk value of the dial indicator, so as to visually detect the numerical range of the perpendicularity.
Description
Technical field
The present invention relates to a kind of squareness measurement frock, belong to measurement manufacture field.
Background technology
Piston type part is one of vitals of a lot of hydraulic system lock class component, plays function play an important role to lock set.Piston and piston rod cooperatively interact and are arranged in lock housing, by respectively to unblank chamber and shut chamber inject oil pressure make lock complete switching function.Verticality is the important morpheme key element of piston details, and the relative position relation of its mainly two end faces of confined piston part and cylindrical of part, requires that the verticality of two of part end faces and part outer axis is not more than 005m.Such piston details could be fitted by end face that is good and piston rod when assembling, ensure that it normally works: traditional measuring method is fixed on the chuck of lathe by the cylindrical of part, dial gauge is utilized to beat to the size measuring part end face, but because the centering error of lathe chuck is larger, can not ensure that the axis of part outer overlaps with the main-shaft axis of lathe, therefore measurement result will be caused to there is error, can not ensure, ensure that product quality is completely controlled.
Summary of the invention
The technical problem to be solved in the present invention is to provide verticality measuring tool, by measuring the verticality of piston details end face and cylindrical axis, avoids the measuring error because plant issue brings, and ensures to measure accurately, easy to operate.
For overcoming the above problems, concrete technical scheme of the present invention is as follows: a kind of squareness measurement frock, base plate upper surface is fixedly connected with two angle seats, be provided with V-block between two angle seats, two angle seats are respectively equipped with handle and dial gauge, and dial gauge side head end runs through seat side end face, angle, spring is provided with between handle and angle seat, spring originates in seat side end face, angle, ends at handle bare terminal end, and dial gauge operating side and handle bare terminal end are all towards V-block.
Preferably, described angle seat is fixedly connected with by screw with base plate.
Preferably, a kind of application of squareness measurement frock, comprises the steps:
1), by piston details be arranged on and detect in frock, fitted in part outer and frock V-type face;
2), by the gauge head of dial gauge be against on the end face to be measured of part, compacting also adjusts dial plate so that reading;
3), rotating part, the diverse location of part end face is contacted with the side head of dial gauge;
4) pointer, observing dial gauge beats situation to determine the verticality scope of part thus to show whether the verticality of part meets the demands
The beneficial effect that the present invention brings is: when detecting verticality, ensure that two end faces of piston details are less than or equal to 0.05mm relative to the verticality of all axis of part outer, by this frock, be the jerk value of dial gauge detected verticality numbers translate, detect the numerical range of verticality intuitively.
Accompanying drawing explanation

Preferably, described angle seat 7 is fixedly connected with by screw 4 with base plate 2.
Preferably, a kind of application of squareness measurement frock, comprises the steps:
1), by piston details be arranged on and detect in frock, fitted in part outer and frock V-type face 3;
2), by the gauge head of dial gauge 1 be against on the end face to be measured of part, compacting also adjusts dial plate so that reading;
3), rotating part, the side head that the diverse location of part end face and percentage 1 are shown contacts;
4) pointer, observing dial gauge 1 beats situation to determine the verticality scope of part thus to show whether the verticality of part meets the demands.
Above-described is only the preferred embodiments of the present invention.It should be pointed out that for the person of ordinary skill of the art, under the premise without departing from the principles of the invention, some modification and improvement can also be made, also should be considered as belonging to protection scope of the present invention.
