Description
Technical field
The utility model belongs to the bearing measuring technical field, is specifically related to a kind of bearing end-play measurement mechanism.
Background technology
Miniature bearing is because overall dimensions is less, and power suffered when its end-play is measured is also less, so the detection of miniature bearing play is generally carried out on X092 type miniature bearing end-play measurement mechanism.The structure of existing measurement mechanism is as shown in Figure 1; Measurement mechanism comprises base 1 and is assemblied in the supporting base 6 on the base through height adjustable structure; On supporting base 6, be equipped with the thrustor that extends along the vertical direction; Thrustor comprises the positioning and guiding cover that is located in the pilot hole; The positioning and guiding cover is fixed on the supporting base through set nut; In positioning and guiding cover from top to bottom successively assembling extend along the vertical direction apply the propulsion arm 19, goring push spring 17 of jacking force upwards and be inserted into the spring base 15 in the positioning and guiding cover through set nut to bearing outer ring, through rotational lock nut 14, can be so that spring base 15 moves adjustment along the vertical direction in the positioning and guiding cover.The height adjustable structure here mainly comprises by stack from top to bottom and is placed on the adjustment shim pack of respectively adjusting 3 one-tenth of shim pack of axially extending along the vertical direction between base and the supporting base.When detecting end-play; Measured bearing 9 is sleeved on the transverse arm depression bar 11 identical with the internal diameter size of bearing inner race, uses the transverse arm push rod 12 more slightly larger than the internal diameter size of bearing inner race that measured bearing is pressed abd fixed on the transverse arm depression bar 11, transverse arm depression bar 11 and transverse arm push rod 12 all are fixed on the baffle plate 5 through trip bolt; Compress eccentric wheel handle 8 then; Operating grip 7 is dialled to left end by right-hand member, this moment, propulsion arm 19 moved under the thrusting action of goring push spring 17 from lower to upper again, and pressed to the outer peripheral face of measured bearing 9 outer rings; Need the gap between observation propulsion arm 19 and the measured bearing 9 this moment; If excesssive gap does not then have numerical value change on the twisted-coil comparator 13, if but press too tight; The end-play numerical value that then measures is bigger than actual value, more than either way need adjust in advance the gap between propulsion arm 19 and the measured bearing 9.Usually adjust through the height adjustable structure between base 1 and supporting base 6,, when height adjustable structure is adjusted the height of supporting base, can realize the gap between propulsion arm and the measured bearing because propulsion arm is assemblied on the supporting base.Existing height adjustable structure is the adjustment shim pack of being made up of several adjustment pad 3 stacks; Adjustment pad through placing different-thickness changes the distance between supporting base and the base; Change the height of supporting base, thereby the gap between propulsion arm and the measured bearing is adjusted.And when installation and removal adjustment pad; Need dismantle earlier and be fixed on 2 erection bolts 2 on the base 1; Increase or reduce adjustment pad 3 then; Again supporting base 6, adjustment pad 3 and base 1 are fixed up through erection bolt 2, and then whether the observation propulsion arm is suitable with the gap between the tested external diameter, if improper then also need adjust to the thickness of adjusting shim pack.The thickness of existing adjustment pad mainly contains three kinds, is respectively 2mm, 1.5mm and 1mm.Need repeatedly adjust the adjustment shim pack when measuring a kind of end-play of model bearing like this, dismantle repeatedly, install, observe, whole adjustment process bothers very much.And, also must use the adjustment pad of some specific thicknesses just can make contact between the outer ring external diameter of propulsion arm 19 and measured bearing suitable for the bearing of some special type.Treat that with contact between the outer ring external diameter of propulsion arm 19 and measured bearing when suitable, this moment, the swinging operation handle 7, the difference of the reading on the twisted-coil comparator 13 is the end-play value of measured bearing 9.If it is bigger to measure the end-play difference of resulting end-play value and calculating, then can become flexible check nut 14, rotating missile spring abutment 15 changes the thrusting action power of 17 pairs of propulsion arms 19 of goring push spring to some extent, finally measures suitable end-play.
Above-mentioned miniature bearing end-play measurement mechanism very is fit to measure the end-play of miniature bearing; But the adjustment preliminary work before measuring is more loaded down with trivial details; Especially need repeatedly adjustment just can make the gap between measured bearing and the propulsion arm suitable, operator's labour intensity was big when this just caused measuring, detection efficiency is low.
The utility model content
The purpose of the utility model is to provide a kind of bearing end-play measurement mechanism, and is loaded down with trivial details and cause the technical matters that operator's labour intensity is big, detection efficiency is low to solve adjustment preliminary work before measurement mechanism of the prior art is measured.
