Abstract
The utility model relates to a structural improvement of bearing clearance measuring instrument, the utility model is mainly characterized in that a lower core shaft is arranged on a seat body and is provided with a location measuring ring at upper end which contacts with inner measuring ring arranged at lower end of the upper core shaft through the inner ring of the to-be-measured bearing; a seat sleeve contacts with outer ring of the to-be-measured bearing arranged at upper end through a bearing seat, and is sensed to a measuring meter via outer side ring above the outer ring of bearing and measuring head bracket, therefore the utility model is characterized by reasonable structure, convenient operation, wide inspection applicability, accurate measurement, small error and high inspection efficiency.
Description
The utility model relates to a kind of detecting instrument of mechanical part, especially to a kind of structural improvement of bearing clearance measuring instrument.
The size of the end-play between the Internal and external cycle of bearing and the middle rolling body thereof directly influence engineering goods this machine vibration, spool beat, rotate performances such as dirigibility, the end-play of measuring bearing exactly for Production of bearing, use one of important means that producer improves the quality of products.For this reason, the someone has proposed the utility application (patent No. 94226448.7) of " bearing clearance detector " by name.The bearing clearance detector comprises gauge head and supporting mechanism thereof, the dynamometry load mechanism, operation electriomagnet mechanism and electromagnetic vibrator, the dynamometry load mechanism comprises, the lower heavy punch lever, on, following position fixing handle, on, the lower heavy punch lever is installed relatively, the gauge head supporting mechanism comprises two spring even component framves that spring leaf is formed up and down, slide plate is adjusted in the upright position, adjust and positioning screw, gauge head horizontal position adjustment dovetail slide block is contained on the spring even component frame, and the gauge head supporting mechanism is contained on the detector casing, operation electriomagnet mechanism comprises two electromagnet, and is intermeshing little, gear wheel and rotation shifting block.But this measuring instrument can not be used to measure the end-play of bearing.
In addition, for the comparatively special bearing of some structures, for example the end-play of double-row angular contact bal bearing can't detect with instrument in the bearing industry at present.Usually adopt manual and detect.Like this, the size of hand-power directly influences the reading size of play, thereby can't satisfy the requirement of the required mensuration precision of bearing clearance, and detection efficiency is low.
Goal of the invention of the present utility model provides a kind of rational in infrastructure, and is easy to operate, measures accurately the bearing end-play measuring instrument that detection efficiency is high.
Goal of the invention of the present utility model mainly is achieved by following technical proposals: described mandrel down is fixed on the pedestal, and its upper end is provided with the location survey circle and contacts with the interior survey circle of being located at the mandrel bottom through the inner ring of bearing to be measured; Described cover for seat contacts through the outer ring of bearing seat with the bearing to be measured of end placed on it, and through being located at the outer survey circle and the head-measuring rack thereof of bearing outer ring top, sensing is to meter.
Below described cover for seat, be provided with web joint, be equipped with cylinder axis down; And be provided with the axle sleeve that fixes with pedestal in the inboard of cover for seat, leave the gap between the web joint of its lower surface and cover for seat.
Described upper end of going up mandrel is provided with cylinder axis; And the upper end of described head-measuring rack extends horizontally to the top of the measuring head of meter.
Therefore, the utlity model has rational in infrastructurely, the device one-piece construction is comparatively simple, easy to operate, and it is wider to detect applicability, measures accurately, and repetitive error is less, detection efficiency height, characteristics such as long service life.
Accompanying drawing 1 is the structural representation of a kind of part section of the present utility model.
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is done to describe further.
Embodiment: pedestal 15 is provided with location survey circle 4 and is provided with down mandrel 13 in it, places on the axle sleeve 2 that links to each other with pedestal 15.Be provided with cover for seat 3 in the outside of described axle sleeve 2, its end is fixed with web joint 16, and is being equipped with the cylinder axis of being located on the pedestal 15 14 below the web joint 16.The lower end of bearing seat 12 passes the outside that pedestal 15 is fixed on cover for seat 3, and its upper end is equipped with measured bearing 1 (workpiece); The outer ring of bearing 1 is provided with outer the survey and encloses 10, and links to each other with last mandrel 8 through spring 9; A side of surveying circle 10 outside is provided with head-measuring rack 5, and the upper end crosses out, and is arranged on the top of the measuring head 60 of meter 6; Meter 6 then is fixed on the pedestal 15.In addition, be located at the cylinder of the utility model top, its cylinder axis 14 links to each other with last mandrel 8, and the latter surveys in the circle 11 in being arranged at.
During measurement, bearing to be measured 1 is arranged on the bearing seat 12, starts the cylinder of top, cylinder axis 14 is driven go up mandrel 8, with the inner ring pressing of bearing 1, fixing; Start the cylinder of being located at the below then, by the upwards motion in the scope of outer ring in its end play of web joint 16, cover for seat 3, bearing seat 12 drive measured bearings 1 of its cylinder axis 14, and by interior survey circle 11 and setting head-measuring rack 5 thereon, make the measuring head 60 of the meter 6 that makes by clock gauge make corresponding mobile, thereby measure the end play of bearing.
