Currently, users are increasingly stringenter bearing requirement, the especially radial internal clearance of deep groove ball bearing, it is desirable to Control in a certain range, is conducive to the service life for improving bearing in this way, reduces noise, improve running accuracy.However, existing There is the measuring device for windage of technology error when measuring to deep groove ball bearing larger, lower pressure rod is directly pushed again by cylinder Bearing outer ring is withstood, because of the size poor controllability of air pressure, and the reason of because of cylinder itself, when down-pressed pole apical axis bearing outer-ring, impact Power is big, and each work pace dynamics is unbalanced.
Utility model content
In view of the defect of the above-mentioned prior art, the purpose of this utility model is that: a kind of deep groove ball bearing radially trip is provided Gap measuring device, measurement error are small.
The technical solution of the utility model is: deep groove ball bearing radial internal clearance measuring device, including pedestal, on pedestal Equipped with rack and bottom plate, the top of the rack is equipped with the bearing tension mechanism of installation bearing, and the top of rack is also equipped with position Upper pressing mechanism above bearing, bottom plate are equipped with the lower pressing mechanism being located at below bearing;
The bearing tension mechanism include the mandrel that front end of rack is set, the tensioning cylinder that rear end of rack is set, with The guide rod of the piston rod connection of tensioning cylinder and the motion bar of guide rod front end is set, mandrel includes that fixed block and being located at is fixed The movable block of Duan Dingduan, motion bar are inserted in the center of mandrel, and when front end of motion bar travels forward up pushes up movable block. When the structure of the prior art is that cylinder directly withstands bearing outer ring, because of the size poor controllability of air pressure, and because of the original of cylinder itself Cause, when down-pressed pole apical axis bearing outer-ring, impact force is big, and each work pace dynamics is unbalanced, and the above error dot subtracts after improvement, Lower pressure is soft, and size easily adjusts, is controllable.
Further, the front end of the mandrel has perforation, and the outer diameter of perforation is less than the outer diameter of motion bar, motion bar front end Equipped with conical head, perforation is penetrated for conical head.
Further, the lower pressing mechanism includes that return cylinder at the top of bottom plate, setting is arranged in is living in return cylinder The down-pressed pole for connecting and being located at below bearing with crossbar end, the limited block of down-pressed pole bottom end is arranged in the cross bar on stopper rod top And the spring between limited block and bottom plate is set.
Further, the piston rod top end of the return cylinder is equipped with pressing plate.
Further, linear bearing is installed among the down-pressed pole.
Further, the upper pressing mechanism includes the upperpush rod being located above bearing and is arranged at the top of upperpush rod Measuring pen, frame top are equipped with a bracket, and reed seat is arranged on bracket, the reed of setting connection upperpush rod, reed on reed seat Seat connection telescopic cylinder.
Using deep groove ball bearing radial internal clearance measuring device provided by the utility model, the beneficial effect is that: return gas When the piston rod of cylinder retracts, cross bar is pushed, and cross bar drives down-pressed pole to move downward, the downward pressing spring of limited block, return cylinder When piston rod stretches out, cross bar is not contacted with down-pressed pole, and down-pressed pole relies only on the resilient contact of spring to outer ring, i.e. down-pressed pole is logical The elastic force for crossing spring goes to contact bearing outer ring, is not directly controlled by return cylinder, and lower pressure is soft, each work pace dynamics It is balanced controllable, reduce error.

Specific embodiment
For it is relatively intuitive, be fully understood by the technical solution of the utility model, now just combine the progress of the utility model attached drawing Unrestricted feature description is as follows:
As depicted in figs. 1 and 2,4 radial internal clearance measuring device of deep groove ball bearing, including pedestal 1, pedestal 1 are equipped with rack 2 With bottom plate 3, the top of rack 2 is equipped with the bearing tension mechanism of installation bearing 4, and the top of rack 2 is also equipped on bearing 4 The upper pressing mechanism of side, bottom plate 3 are equipped with the lower pressing mechanism for being located at 4 lower section of bearing;
Bearing tension mechanism include the mandrel 4 that 2 front end of rack is set, the tensioning cylinder 6 that 2 rear end of rack is set, with The guide rod 7 of the piston rod connection of tensioning cylinder 6 and the motion bar 8 that 7 front end of guide rod is arranged in, mandrel 4 includes 51 He of fixed block Movable block 52 positioned at fixed section top, motion bar 8 are inserted in the center of mandrel 4, and will when the front end of motion bar 8 travels forward Movable block 52 up pushes up.
As shown in Fig. 2, mandrel 4 is divided into two parts by two cutting lines by mandrel 4, the angle between two cutting lines It is 120 degree.
The front end of mandrel 4 have perforation 9, perforate 9 outer diameter be less than motion bar 8 outer diameter, 8 front end of motion bar be equipped with taper First 10, perforation 9 is penetrated for conical head 10.Motion bar 8 can strut the movable block 52 of mandrel 4 after travelling forward.
Lower pressing mechanism includes the return cylinder 11 that 3 top of bottom plate is arranged in, is arranged in 11 piston rod top end of return cylinder Cross bar 12, connect with 12 end of cross bar and the down-pressed pole 13 for being located at 4 lower section of bearing, the limited block that 13 bottom end of down-pressed pole is set 14 and the spring 15 that is arranged between limited block 14 and bottom plate 3, linear bearing 16, return cylinder are installed among down-pressed pole 13 11 piston rod top end is equipped with pressing plate 111.Specifically, when the piston rod of return cylinder 11 retracts, pressing plate 111 will be under cross bar 12 Pressure, cross bar 12 drive down-pressed pole 13 to move downward, the downward pressing spring 15 of limited block 14, when the piston rod of return cylinder 11 stretches out, Cross bar 12 do not contacted with down-pressed pole 13 (such as can be set down-pressed pole 13 upper end outer diameter it is small, lower end outer diameter is big, the activity of cross bar 12 Cover on down-pressed pole 13), down-pressed pole 13 relies only on the resilient contact of spring 15 to outer ring.
Upper pressing mechanism includes the upperpush rod 17 for being located at 4 top of bearing and the measuring pen that 17 top of upperpush rod is arranged in 18, it is equipped with a bracket 19 at the top of rack 2, reed seat 20 is set on bracket 19, the spring of setting connection upperpush rod 17 on reed seat 20 Piece 22, reed seat 20 connect telescopic cylinder 21, and when the meeting stopper rod of telescopic cylinder 21 retracts, reed 22 is relaxed, and upperpush rod 17 is logical It crosses the resilient contact of reed 22 and pushes down 4 outer ring of bearing.
The application method of the utility model is as follows:
Bearing 4 is first pushed into mandrel 4, tensioning cylinder 6 works and motion bar 8 is driven to travel forward, and motion bar 8 is with moving mandrel 4 movable block 52 moves upwards, and is fixed 4 inner-ring-tension of bearing with movable block 52, and then reed 22 loosens, and upperpush rod 17 declines And contact and push down 4 outer ring of bearing, first numerical value of measuring pen 18 is read at this time, and then the piston rod of return cylinder 11 is stretched upwards Out, down-pressed pole 13 moves upwards by the elastic force of spring 15 and touches 4 outer ring of bearing, second for then reading measuring pen 18 Numerical value, it is exactly radial internal clearance that second of numerical value, which subtracts first time numerical value,.
