Abstract
The utility model relates to an instrument for measuring the single-sided convex value of a bearing, which is characterized in that a pressure device transfers pressure to a bearing through a pneumatic piston rod; and the instrument is used for measuring the convex value when the bearing is under stress, namely the height difference between an inner ring and an outer ring. The utility model has the advantages of simple and easy assembly, simple and easy adjustment, high measurement efficiency, good instrument stability and wide application model.
Description
Technical field
The utility model relates to a kind of surveying instrument, relates in particular to a kind of surveying instrument of bearing face protrusion amount.
Background technology
Along with the develop rapidly of modern machine industry, precision high speed chief axis adopts paired duplex or multi-joint bearing as support pattern usually, to substitute traditional single cover bearing support pattern.Comparatively speaking, matched bearings is at rigidity, position stability and be subjected to all many-sides such as axial displacement under the external force effect obviously to be better than single cover bearing to support, thereby particularly is widely adopted on the precision high speed chief axis at machine industry.
Angular contact ball bearing adopts the supporting as main shaft of duplex or multi-joint group mode usually, yet whether the apolegamy of matched bearing is successful, key is whether the protrusion amount of bearing under Axial Loads mates, so the measurement of bearing face protrusion amount just becomes the key of its assembly.The protrusion amount not only influences precision, rigidity, vibration and the noise of instrument and equipment, and directly influences the life-span of bearing.Thereby the end face protrusion amount that accurately measures angular contact ball bearing has great importance.And the bearing protrusion measuring of prior art is loaded down with trivial details, and precision is low, poor stability.
Summary of the invention
The purpose of this utility model: mainly be to solve the deficiencies in the prior art, thereby develop a kind of instrument of fast, accurately measuring bearing single face protrusion amount.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: a kind of instrument of measuring bearing single face protrusion amount, it is characterized in that: have pedestal, the upper and lower mould that is suitable for placing measured bearing is arranged on the pedestal, steel ball is arranged above the mold, the pressure apparatus that adopts cylinder is housed on the steel ball, measurement instrument is arranged in the side of upper and lower mould; Measuring instrument is installed on the adjustable for height dial framework.
The technical solution of the utility model can also be further perfect:
As preferably, described cylinder is fixed on the stand, and voltage stabilizer is communicated with cylinder.
As preferably, upper and lower mould is respectively equipped with short slot one and short slot two.Protrusion amount that like this can measured angular contact ball bearing two sides makes things convenient for any assembly of bearing.
As preferably, voltage stabilizer is provided with pressure regulator and reversal valve.
Feature of the present utility model is that the pressure device transmits pressure to bearing, the protrusion amount during the apparatus measures shaft strength by pneumatic piston rod.
The beneficial effects of the utility model are: frock is simple and easy, adjust simple and easy, the efficiency of measurement height, stability of instrument is good, the applicable model of instrument is wide.

Embodiment
Below by embodiment also in conjunction with the accompanying drawings, technical scheme of the present invention is further described in detail.
Embodiment:
As Fig. 1-shown in Figure 8, have pedestal 09, bed die 05 is arranged on the pedestal, mold 03 has the short slot 2 51 of symmetric arrangement on the bed die 05, the short slot 1 of symmetric arrangement is arranged on the mold 03, protrusion amount that like this can measured angular contact ball bearing two sides makes things convenient for any assembly of bearing.On up and down between the mould, place measured bearing 04, steel ball 03 is arranged above the mold, cylinder 06 is housed on the steel ball, cylinder is fixed on the stand 07, the pressure gas of cylinder provides by voltage stabilizer 01, pressure regulator 10 and reversal valve 11 are housed on the pedestal 09, last, there is measuring instrument 08 side of bed die, fixed block 13 links to each other with dial framework 21, meter jaw 20 and gauge head folder 16 are fixed on the fixed block 13, instrument 19 is installed on the meter jaw 20, measuring head 17 links to each other with gauge head folder 16 by rotary main shaft 18, and baffle plate 15 also is fixed on the gauge head folder 16, and nut 14 links to each other with baffle plate 15, the thickness that can adjust pad 22 between dial framework 21 and fixed block 13 is regulated the height of measuring point, and also 14 pairs of measuring points of adjustable nut are finely tuned.
Measuring process is:
The first step according to the size and the applying working condition of bearing, is pressed standard-required and is regulated voltage stabilizer 01, and cylinder 06 is adjusted to standard-required pressure.
Second step, select corresponding upper and lower mould 03,05, select the position of mould up and down according to the pairing mode of bearing, patrix 03 cooperates with the outer ring large end face of angular contact ball bearing, and counterdie 05 cooperates with bearing inner race.If the DB pairing mode, then patrix 03 is last, and 05 following; If the DF matching method, then counterdie 05 is last, and 03 following.
In the 3rd step, the height of adjustment surveying instrument is taken baffle plate 15 and dial framework 21 apart, according to pad 22 thickness between the height increase baffle plate 13 that will adjust and the dial framework 21, uses screw fixed dam 13 and dial framework 21 again, and 14 pairs of measuring points of setting nut are finely tuned then.
The 4th step was placed on bearing between patrix 03 and the counterdie 05 as requested, and applies certain axle pressure, and measuring instrument 08 is measured the inner ring of bearing both direction and the difference in height of outer ring, and measured numerical value is averaged, and this value is exactly the protrusion amount of bearing.
