Description
Technical field
The utility model relates to the cubing that a kind of calibration is measured, and relates in particular to the cubing that a kind of flexible star jacketed-ball groove calibration is measured, and belongs to the measurement mechanism technical field.
Background technology
The calibration measuring method of star jacketed-ball groove often adopts three coordinate measuring machine respectively six alleys to be got a little, measures the theoretical center of each alley, calculates scale division value again; Its complicated operation, Measuring Time is long, needs to carry out in sensing chamber, is not suitable for online 100% measurement, so can not effectively in time control the inner race product quality.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, and a kind of flexible star-sleeve tracking indexing detecting tool is provided, and it is low that this indexing detecting tool system is hanked, and precision is high, and is easy to operate, adapts to online 100% and measures, and especially is fit to how interracial fast quick change tool.
According to the technical scheme that the utility model provides, flexible star-sleeve tracking indexing detecting tool comprises base plate, measurement flat board, limited block, the first cover plate, the first survey ball, the second survey ball, the second cover plate, cushion block, gauge stand, clock gauge; Fixation measuring flat board and backing plate on the upper surface of base plate, limited block is installed on the backing plate, the limited block upper surface is provided with the first cover plate and the second cover plate, first surveys ball is located between the first cover plate and the cushion block, second surveys ball is located between the second cover plate and the cushion block, the flat gauge head of clock gauge props up second and surveys ball, and clock gauge is fixed by screws on the gauge stand.
As further improvement of the utility model, described the first cover plate is provided with the conical surface, and the conical surface can make first to survey within the specific limits Free-rolling of ball.
As further improvement of the utility model, described the second cover plate is provided with the conical surface, and the conical surface can make second to survey within the specific limits Free-rolling of ball.
Compared with the prior art the utility model has the following advantages:
The utility model is simple in structure, compact, rationally, easy to operate, can 100% on-line measurement, especially be fit to how interracial fast quick change tool, greatly improved the stability of production efficiency and product quality; Can be vast medium and small enterprise provides the star jacketed-ball groove calibration measuring method of a kind of low cost, high precision, high flexibility.
Description of drawings
Fig. 1 is structural front view of the present utility model.
Fig. 2 is structure vertical view of the present utility model.
Embodiment
Following the utility model is further described in connection with the embodiment in the accompanying drawing:
As shown in Figure 1 and Figure 2, the utility model is mainly surveyed ball 6, the second cover plate 7, cushion block 8, gauge stand 9, clock gauge 10 and screw etc. and is formed by base plate 1, measurement flat board 2, limited block 3, the first cover plate 4, the first survey ball 5, second.
Fixation measuring dull and stereotyped 2 and backing plate 8 on the upper surface of base plate 1, limited block 3 is installed on the backing plate 8, limited block 3 upper surfaces are provided with the first cover plate 4 and the second cover plate 7, first surveys ball 5 between the first cover plate 4 and cushion block 8, the conical surface 12 of the first cover plate 4 guarantees that first surveys within the specific limits Free-rolling of ball 5, second surveys ball 6 between the second cover plate 7 and cushion block 8, the conical surface 11 of the second cover plate 7 guarantees that second surveys within the specific limits Free-rolling of ball 6, the flat gauge head of clock gauge 10 props up second and surveys ball 6, and clock gauge 10 is fixed by screws on the gauge stand 9.
Principle of work of the present utility model and the course of work
First surveys the two adjacent alley close contacts that ball 5 and second is surveyed ball 6 and inner race, two survey the centre distance of ball and the linear variation of angle of the adjacent alley of tested inner race within the specific limits, the numerical value that clock gauge 10 shows is the centre distance variable quantity of two survey balls, can calculate the angle variable quantity of the adjacent alley of inner race by converting.
When measuring the inner race scale division value, need first to cubing of the present utility model school zero, calibrating device is placed in the measurement dull and stereotyped 2, be pushed into two and survey the ball location, two alleys of calibrating device and two are surveyed the ball close contact, first surveys ball 5 is close to limited block 3 sides, and the flat gauge head of clock gauge 10 withstands second and surveys ball 6, according to the actual measurement deviate at calibrating device and technique zero point, if the zero migration value of clock gauge 10, finish school zero, take out calibrating device, then inner race to be measured is placed on and measures on dull and stereotyped 2, be pushed into two and survey the ball location, adjacent two alleys of inner race and two are surveyed the ball close contacts, and first surveys ball 5 is close to limited block 3 sides, the reading changing value of clock gauge 10 be exactly two survey ball center apart from the deviate of standard component, by converting, calculate the angle of adjacent two alleys of inner race, then take out inner race, measure successively other alley.
