Description
Technical field
A kind of measurement frock is the utility model is related to, more particularly, to a kind of measurement work of four-point contact ball clearance
Dress.
Background technology
It is known, precision bearing, it is widely used in the fields such as automobile, engineering machinery, machine tool chief axis；Four-point contact ball
It is one kind of precision bearing, is a kind of divergence type bearing, a set of bearing can bears bi-directional axial load；Its inside and outside circle raceway is cut
Noodles are like peach type, and when no-load or the effect of purely radial load, steel ball and lasso are rendered as 4 points of contacts, four-point contact ball
Holding can normal work in two-point contact.The big resultant load occasion of purely axial load or axial load is applied in general to, is also fitted
The occasion to be run at high speed together in those.And the size of four-point contact ball end-play directly affects the life-span of bearing, so
Effective measurement end-play is very crucial；QJ type four-point contact ball two halves inner rings, will generally be twisted using pressing plate by screw
Tightly, two inner rings are fixed；Detection clearance manually is placed in measuring instrument, and this method, which detects a product, just to be needed to twist screw bag twice
Include and tighten, unclamp step, and because tightening degree Different Effects measure repeatable accuracy.Conventional method measurement efficiency is low, makes whole
Production efficiency is affected, cost increase.
The content of the invention
In order to overcome the shortcomings of in background technology, the utility model discloses a kind of measurement of four-point contact ball clearance
Frock.
In order to realize the goal of the invention, the utility model adopts the following technical scheme that：
A kind of measurement frock of four-point contact ball clearance, including measurement apparatus, supporting leg, lower platen, upper press cover and spiral shell
Nail, is provided with four-point contact ball, at the bottom interval of four-point contact ball on the step surface in step-like lower platen
Four supporting legs uniformly are provided with, step through-hole is provided with the middle part of lower platen, is provided with and compresses on the step surface in the middle part of lower platen
Spring, pillar are arranged in the through hole in the middle part of lower platen through holddown spring, and the upper press cover is arranged on four-point contact ball
Above, the middle part on upper press cover is provided with the screw fixed with pillar, and the measurement apparatus is arranged on the side of supporting leg
Portion.
The measurement frock of described four-point contact ball clearance, the measurement apparatus include amesdial, pole and dial framework,
Dial framework is disposed therein outside the side of a supporting leg, and the pole of fixed amesdial, the table of amesdial are provided with the top of dial framework
The upper plane contact of point and screw.
The measurement frock of described four-point contact ball clearance, the top bar diameter and four-point contact ball of lower platen
Internal diameter it is equal.
By adopting the above-described technical solution, the utility model has the advantages that：
The measurement frock of four-point contact ball clearance described in the utility model, solve because traditional frock tightens degree
The problem of measurement unstability that different band is come, by setting holddown spring, human intervention is reduced, realizes and improves measurement reproducibility
Precision；By holddown spring compress upper press cover can quick insertion, realize the purpose that quickly measures, be measured extraction, can be quick
A product is loaded, and next product measurement can be achieved in quick insertion lower platen.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
In figure：1st, amesdial；2nd, pole；3rd, dial framework；4th, screw；5th, upper press cover；6th, four-point contact ball；7th, push
Plate；8th, pillar；9th, holddown spring；10th, supporting leg.
