Abstract

The utility model discloses a tooling for measuring labyrinth seal rings, which comprises a body. One end of the body is provided with a handholding portion, the other end of the body is provided with a first boss, a second boss and a third boss, a first groove is arranged between the first boss and the second boss, a second groove is arranged between the second boss and the third boss, and heights of the first boss and the second boss are lower than the height of the third boss. The tooling for measuring the labyrinth seal rings has the advantages of being easy to measure deep and narrow grooves of the labyrinth seal rings, accurate in measurement, and the like.

Description

Be used to measure the frock of labyrinth seal ring

Technical field

The utility model relates to a kind of measurement frock, relates in particular to a kind of frock that is used to measure the labyrinth seal ring of bearing labyrinth end cap.

Background technology

The mode of labyrinth seal ring that existing measurement has the bearing labyrinth end cap of dark narrow groove is to measure through calliper; Can also meet the demands basically for measuring outer labyrinth seal ring; But in measuring during the dark narrow groove of labyrinth seal ring; Sometimes calliper stretches into and but is difficult in the dark narrow groove measure accurately, and there is gross error in this metering system.Yet inside and outside labyrinth seal ring cooperates requirement than higher, can only lean on lathe to guarantee that the size in uncontrollable labyrinth is brought certain degree of difficulty to producing this workpiece.

Summary of the invention

The purpose of the utility model is the deficiency that overcomes prior art, and a kind of dark narrow groove of labyrinth seal ring that is easy to measure is provided, and measures the frock that is used to measure labyrinth seal ring accurately.

The technical scheme that realizes above-mentioned purpose is: a kind of frock that is used to measure labyrinth seal ring; Comprise body; One end of said body has the Handheld Division, and its innovative point is: the other end of body has first boss, second boss and the 3rd boss, has first groove between said first boss and second boss; Have second groove between second boss and the 3rd boss, the height of said first boss and second boss is lower than the height of the 3rd boss.

In technique scheme, said first boss is concordant with the upper end of second boss, and said first groove is identical with the groove depth of second groove.

The width of the upper end of said first boss and second boss is less than the width of its bottom, and the width of the upper end of the 3rd boss is identical with the width of bottom.

The Handheld Division of said body is laminar.

The beneficial effect of the utility model is: because an end of the body of the utility model has the Handheld Division; The other end has first boss, second boss and the 3rd boss, has first groove between said first boss and second boss, has second groove between second boss and the 3rd boss; The height of said first boss and second boss is lower than the height of the 3rd boss; The utility model is of a size of the size and the maximum error sum of the dark narrow groove of labyrinth seal ring, during use, is benchmark with the side one of one of them boss of the utility model; Insert in the labyrinth seal ring of labyrinth seal end cap; If all boss of the utility model all can rotate a circle around the labyrinth face, and the bottom of the dark narrow groove of the labyrinth seal ring of the upper end of all boss and labyrinth seal end cap is when having certain spacing, and then this labyrinth seal ring is qualified.The utlity model has simple in structurely, be easy to measure the dark narrow groove of labyrinth seal ring, and measure advantages such as accurate.

Fig. 2 is the left view of Fig. 1;

Fig. 3 is the vertical view of Fig. 1;

Fig. 4 is the user mode figure of the utility model.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Like Fig. 1,2,3, shown in 4; A kind of frock that is used to measure labyrinth seal ring comprises body 1, and an end of said body 1 has Handheld Division 1-6; The other end of body 1 has the first boss 1-1, the second boss 1-2 and the 3rd boss 1-3; Have the first groove 1-4 between the said first boss 1-1 and the second boss 1-2, have the second groove 1-5 between the second boss 1-2 and the 3rd boss 1-3, the height of the said first boss 1-1 and the second boss 1-2 is lower than the height of the 3rd boss 1-3.

Like Fig. 1, shown in 4, in order to improve the degree of accuracy that the utility model is measured, reduce measuring error, and adaptive with labyrinth seal ring, the said first boss 1-1 is concordant with the upper end of the second boss 1-2, and the said first groove 1-4 is identical with the groove depth of the second groove 1-5.The width of the upper end of the said first boss 1-1 and the second boss 1-2 is less than the width of its bottom, and the width of the upper end of the 3rd boss 1-3 is identical with the width of bottom.

Like Fig. 1, shown in 2, for the ease of operation, the Handheld Division 1-6 of said body 1 is laminar.

When the utility model uses; Left surface with the first boss 1-1 of body 1 is a benchmark; Insert in the labyrinth seal ring of bearing labyrinth end cap 2, if the end of all boss of the utility model all can rotate a circle around the labyrinth face, and the bottom of the dark narrow groove of the upper end of all boss and labyrinth seal ring is when having certain spacing; This spacing is that then this labyrinth seal ring is qualified in the error range that dark narrow groove allows in the labyrinth seal ring.In addition, in order to be suitable for the labyrinth seal ring of plurality of specifications size, can process the measurement frock of multiple fit size; The utility model generally selects for use tool steel or spring steel material on wire cutting machine tool, to process; Carry out Quenching Treatment then, and the general HRC55 of hardness～60, process more convenient; The Bao Yuehao more of the thickness processing of the utility model can improve the accuracy of measurement.
