Further, telescopic rod 4 is provided on the telescopic end of the electric pushrod 3, the telescopic rod 4 includes fixed setting In the fixed column 41 on the telescopic end of the electric pushrod 3 and the telescopic mast that can be movably arranged in the fixed column 41 42, Screw assembly has clamping screw 411, the lock on the periphery wall of end of the fixed column 41 far from the electric pushrod 3 Tight bolt 411 passes through the fixed column 41 and is pushed against on the telescopic mast 42, the telescopic direction of the telescopic mast 42 and the electricity The telescopic direction of dynamic push rod 3 is perpendicular, and the telescopic mast 42 is hinged with mounting blocks 43 far from the end of the fixed column 41, described Screw assembly has amesdial 5 on mounting blocks 43；Wherein telescopic mast 42 and the cross section of fixed column 41 are square, and avoid stretching Column 42 rotates in fixed column 41, in addition to being moved easily telescopic mast 42, the both ends of telescopic mast 42 can run through fixed column 41, I.e. the both ends of telescopic mast 42 protrude from except fixed column 41, by pull end of the telescopic mast 42 far from mounting blocks 43 to its into Row movement.

Further, the mounting blocks 43 are mounted on the telescopic mast 42 by articulated shaft 421, the articulated shaft 421 The equal Screw assembly in both ends have hex nut 422, the hex nut 422 is pushed against on the mounting blocks 43.

Further, the lead screw 12 is mounted on the station 1 by two fixed plates of different sizes, the silk One end of thick stick 12 is fixedly installed crank 121.

Further, the second connecting rod 112 is provided with the idler wheel that can be rotated, institute close to the end of the arc groove 21 It states idler wheel and rolls and be arranged in the arc groove 21.

It is further noted that although the application can be realized the automatic positioning of bearing, it is not intended that can The bearing of all sizes is positioned, the application does not limit the parameter of the features such as first connecting rod, second connecting rod and sliding block specifically, User can position different size of bearing with the hunting range of sets itself first connecting rod to realize in actual use；Such as The length of first connecting rod can be 20cm, and the length of second connecting rod is 10cm, and the angle of first connecting rod and second connecting rod is 120 °, The corresponding central angle of arc groove is 80 °, and the corresponding chord length of arc groove is 8cm, and the distance at two link rotatable centers is 20cm, fixed Vertical range of the position plate 14 apart from station center is 1.5cm.

In use, auxiliary positioning unit 6 is put into locating slot 16 first, top pillar 63 is retracted by first rotating shaft 61, Then detected bearing is placed between two connecting rods and positioning plate 14, then rotates crank 121 and lead screw 12 is driven to rotate, And then push connecting rod to clamp bearing by sliding block 2, after connecting rod clamping, first rotating shaft 61 is then rotated, top pillar 63 is pushed against It on the inner ring of bearing, and is locked by the second locking nut 612, then passes through the first locking nut 65 again for T-type cylinder 66 Locking, positioning while bearing inner race and outer ring can be realized, it should be noted that connecting rod should not be too large the clamping force of bearing, As long as guaranteeing that bearing does not shake；Then by adjusting the position of electric pushrod 3 and telescopic mast 4, by the contact tune of amesdial 5 It is whole on the corresponding position of bearing, bearing can be detected；

When needing to detect bearing both side surface, first, in accordance with aforesaid operations method by the inner ring and outer ring of bearing Positioning, is then adjusted the contact of amesdial 5 to vertical state by hex nut 422, as shown in fig. 7, then by flexible Bar 4 is good by the horizontal position adjustment of 5 contact of amesdial, is located at the surface of detected surface, then passes through electric pushrod 3 Band moving contact declines, so that contact is pushed against in detected surface and stops electric pushrod 3, records the degree of amesdial 5 at this time, Then by pushing telescopic mast 42, amesdial 5 is driven to move horizontally, (note of discontinuity can be used in the reading of record amesdial 5 Record, such as the one stroke of contact record 3 times), the reading of record is finally depicted as line chart, and to can be obtained bearing surface recessed The amplitude of variation of convex degree；

When needing the inner ring to bearing to detect, the inner ring and outer ring of bearing is determined first, in accordance with aforesaid operations method Position, is adjusted the contact of amesdial 5 to heeling condition by hex nut 422, as shown in figure 8, first passing through electric pushrod 3 will touch Head is reduced in the inner ring of bearing, i.e., then contact will pass through moving telescopic column 42 lower than the upper surface for being detected bearing at this time, Contact is pushed against on inner ring, and records the reading of amesdial 5 at this time, is then locked telescopic mast 42 by clamping screw 411, It is then again started up electric pushrod 3, band moving contact declines, and records the reading of amesdial 5, similarly can also be using discontinuity Recording mode, but to stop electric pushrod 3 while recording reading, the reading of record is finally depicted as line chart Obtain the amplitude of variation of bearing surface bumps degree；It should be noted that measurement when top pillar 63 position to avoid amesdial 5 touch The measurement position of head, in case top pillar 63 interferes the movement of contact；In addition when carrying out bearing inner race measurement, guarantee connecting rod position not It is dynamic, the first locking nut 65 is unclamped, bearing inner race can be driven to be freely rotated by turning T-type cylinder 66, to measure inner ring Different location

Mode of operation phase when needing to detect bearing outer ring, when mode of operation is detected with the inner ring to bearing Together, it is only necessary to adjust contact to the outer ring of bearing, while it is noted that connecting rod cannot interfere the movement of contact；Guaranteeing In the case that auxiliary positioning unit 6 is motionless, unclamp connecting rod can rolling bearing outer ring, to measure the different positions of outer ring It sets

It is examined when being detected to bearing both side surface, when the inner ring to bearing detects and to bearing outer ring When survey, the path that amesdial 5 detects is straight line, when needing to detect bearing other positions, can be detected in last time On the basis of rolling bearing so that contact be aligned the position to be detected, then according to above-mentioned detecting step detect.

In addition, according to the characteristic of the measurement of amesdial 5, (amesdial, which belongs to, compares measurer, can only measure opposite numerical value, no Absolute figure can be measured), therefore when being detected to bearing both side surface, 5 absolute vertical of amesdial is not required, is not required yet When the inner ring to bearing detects, amesdial 5 specifically how much spend by inclination, as long as guaranteeing that amesdial 5 can be steady in measurement Gu on mounting blocks 43, and contact is pushed against on bearing, at the same reading when to wait 5 pointer of amesdial stablize after again It reads.

The device in the utility model realizes the positioning of bearing by the effect of sliding block and connecting rod, determines one using 3 points The positioning of the principle and auxiliary positioning unit of a circle, and then realize the positioning of bearing, pass through two tops in auxiliary positioning unit Column moves synchronously the positioning for realizing bearing inner race, realizes the positioning of bearing outer ring by moving synchronously for two connecting rods, and lead to Bearing side, inner ring and outer ring concave-convex surface degree are measured in the horizontal movement of the vertical movement and telescopic rod of crossing electric pushrod Amplitude of variation.

Obviously, it is practical without departing from this can to carry out various modification and variations to the utility model by those skilled in the art Novel spirit and scope.If in this way, these modifications and variations of the present invention belong to the utility model claims and Within the scope of its equivalent technologies, then the utility model is also intended to include these modifications and variations.
