Description

Measuring device for inner hole retainer ring groove

Technical Field

The utility model relates to a measuring tool technical field, concretely relates to hole retaining ring measuring device for groove.

Background

The hole is fixed in the round hole by a retainer ring for fixing the axial movement of the parts, and the outer diameter of the retainer ring is slightly larger than the diameter of the assembling round hole. During installation, the clamp spring clamp is required to be used, the clamp mouth is inserted into the clamp hole of the retainer ring, and the retainer ring is clamped tightly and can be placed into the retainer ring groove in the pre-processed round hole.

In the actual production process, because the groove of the retainer ring groove is narrow and small, and no special measuring tool is provided, the error is large when the traditional measuring tool is used for measuring, the size of the machined retainer ring groove cannot meet the requirement, and the assembly precision is low.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome above-mentioned not enough, provide a hole keeps off measuring device for ring groove, simple structure can measure the hole and keep off the ring groove, prepares for follow-up assembly.

The purpose of the utility model is realized like this:

the utility model provides a hole stop ring measuring device for groove, includes base, pivot, spring and clamp plate, pivot eccentric settings is on the base, the clamp plate is connected at the pivot top, and the bottom is equipped with the contact, the spring housing is established in the pivot, and the spring is located between clamp plate and the base.

Preferably, the rotating shaft is provided with a shaft check ring corresponding to the base, and the shaft check ring limits the rotating shaft.

Preferably, the contact piece and the rotating shaft are integrally formed or split.

Preferably, the upper end face of the pressing plate and the upper end face of the base are kept horizontal, the lower end face of the base is provided with a spigot, and the bore diameter of an inner bore of the retainer ring for the mounting hole is matched with the spigot.

The utility model has the advantages that:

the utility model discloses simple structure can measure the inner bore retainer ring groove, prepares for follow-up assembly.

Detailed Description

Referring to fig. 1-7, the utility model relates to a hole retaining ring is measuring device for groove, including base 1, pivot 2, spring 3 and clamp plate 4, pivot 2 inserts in the base 1 and skew base center, clamp plate 4 is connected at 2 tops of pivot, and the bottom is equipped with

contact

5, 3 covers of spring are established in pivot 2, and spring 3 is located between clamp plate 4 and the base 1, pivot 2 corresponds base 1 and is equipped with axle retaining ring 6, axle retaining ring 6 is spacing to pivot 2, and contact 5 warp when preventing to carry pivot 2 in the handling.

The upper end face of the pressing plate 4 and the upper end face of the base 1 are kept horizontal, the lower end face of the base 1 is provided with a spigot, and the bore diameter of an inner bore of a retainer ring for a mounting hole is matched with the spigot.

The contact piece 5 and the rotating shaft 2 are integrally formed.

Contact 5 and pivot 2 are split type, according to hole aperture size, select suitable contact, and the commonality is good, and contact 5 passes through the bolt to be fixed with the pivot, and the bolt setting guarantees the precision of split type structure at the axial and the bottom surface of pivot, reduces measuring error.

A method for measuring an inner hole retainer groove comprises the following steps:

step one, measuring the thickness of the contact piece 5, and recording as t;

step two, the base 1 is arranged at one end of an inner hole of a workpiece to be detected, the rotating shaft 2 extends into the inner hole, and the rotating shaft 2 is eccentrically arranged on one side of the inner hole and the contact piece 5 is far away from the side because the rotating shaft 2 is eccentrically arranged on the base 1;

pressing the plate 4 downwards, compressing the spring 3, enabling the contact piece 5 to reach the position below the retainer ring groove 7, loosening the pressing plate 4 while rotating the rotating shaft 2, driving the contact piece 5 to be screwed into the retainer ring groove 7 by the rotating shaft 2, and limiting the contact piece 5 in the retainer ring groove 7;

stopping the rotation of the rotating shaft 2, pressing the plate 4 downwards, driving the contact piece 5 downwards by the rotating shaft 2, contacting the lower end surface of the contact piece 5 with the bottom of the retainer ring groove 7, and measuring the distance from the upper surface of the pressing plate 4 to the upper surface of the base 1 by a caliper, which is recorded as h 1;

step five, loosening the pressure plate 4, resetting the spring 3, enabling the upper end surface of the contact 5 to contact the top of the retainer ring groove 7, and measuring the distance from the upper surface of the pressure plate 4 to the upper surface of the base 1 by using a caliper, wherein the distance is recorded as h 2;

step six, calculating the thickness of the retainer ring groove 7, and using h to represent the measured thickness of the retainer ring groove:

H=h2-h1+t；

and seventhly, rotating the rotating shaft 2, screwing the contact 5 out of the retainer groove 7, and then taking down the measuring device.

In addition to the above embodiments, the present invention also includes other embodiments, and all technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
