Abstract
The invention discloses a gauge for measuring an A value of a lifting socket of a lever. The gauge comprises a cylindrical positioning post, a sliding block, a graduated scale and a positioning block, wherein the upper part of the positioning post is a half round post; two elongated positioning grooves in the horizontal direction are formed in the sliding block; two positioning bolts respectively penetrate through the two elongated positioning grooves and a central shaft of the positioning post so as to fix the positioning block on a plane of the upper half round post of the positioning post; the graduated scale is horizontally fixed at the lower part of the sliding block and one side of scales on the upper surface of the graduated scale leans against the sliding block; the positioning block is fixed at the end part of the right end of the sliding block in a vertical upward mode. The gauge disclosed by the invention has the benefits of simple structure, convenience for measurement of the lifting socket of the lever, simple operation and accuracy for measurement.
Description
Technical field
The present invention relates to survey tool technical field, a kind of gauge for measuring lever flap seat A value.
Background technology
It is illustrated in figure 1 the brake rigging that current passenger train main flow uses, its operation principle is: is produced brake force by unit brake cylinder 1 and promotes the brake lever 2 with lever flap seat 3 as axis oscillating, brake force is transmitted and amplifies, thus promote brake pad 4 to contact formation friction pair with brake disc 5, make operating passenger vehicle stop.Because passenger train vehicle is different, possessing different carriage tare weights, thus need different brake force, the mode of change brake force is to be realized by the ratio of different lever flap seat A value motivation of adjustment arms with resistance arm.
This brake rigging carries out needing to carry out decomposing then to carry out checking, repairing during A3, A4 level is repaired at passenger vehicle totally, consistent for guaranteeing the brake force that 8 set brake riggings used on each passenger vehicle produce, need lever flap seat A value is measured piece by piece, confirmed.Lever flap seat A value is designed with 16 kinds by designer altogether by the difference of carriage tare weight.
In the operating process measuring lever flap seat A value, actually measure on lever flap seat 3 and be in the axial hole in different operating face and the distance between center line in vertical hole.Owing to there is no the special utensil measuring lever flap seat A value at present, the dip stick combination that operator are only capable of using 2-3 part universal carries out the measurement of A value, concrete operations are as shown in Figure 2,3 universal dip sticks (precision is 0.5mm) are used to be applied in combination, first find out, with dip stick one C1, dip stick three C3, two centerline holes that need to measure, re-use dip stick two C2 and carry out the measurement of A value.This operational approach efficiency is low and measurement error easily occurs.
Summary of the invention
The goal of the invention of the present invention is: for the problem of above-mentioned existence, it is provided that a kind of gauge for curb girder lever flap seat A value, simple in construction, easy to operate, measurement accuracy is good.
The technical solution used in the present invention is such that
A kind of gauge for measuring lever flap seat A value, including cylindrical locating dowel, sliding shoe, rule and locating piece, described locating dowel top is semicolumn, the strip locating slot of two horizontal directions is set on described sliding shoe, and locating piece is fixed in the plane of locating dowel top semicolumn through the central shaft of strip locating slot and locating dowel by a bolt respectively, described rule is horizontally fixed on the scale side of sliding shoe bottom and upper surface against sliding shoe, and described locating piece is vertically upright fixed on sliding shoe right-hand member end.Article two, strip locating slot can ensure that the stable action that sliding shoe slides.
As preferably, described locating piece is connected by two bolts and sliding shoe right-hand member end are fixing.Two bolts i.e. can ensure that locating piece is fixed on sliding shoe well, achieves again detachable.
As preferably, axis tag block is set above described rule on the axis of locating dowel semicolumn plane.After having had axis tag block, more convenient when reading.
In sum, owing to have employed technique scheme, the invention has the beneficial effects as follows: simple in construction, measure lever flap seat A value very convenient, simple to operate, measure accurately.
