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 shown in Figure 1,4 device for measuring axial clearance of deep groove ball bearing, including pedestal 1, pedestal 1 are equipped with rack 2 and bottom
Plate 3, the intermediate side of rack 2 are equipped with the fixed station 5 for placing bearing 4, and the top of rack 2 is equipped with upper above bearing 4
Pressing mechanism, bottom plate 3 are equipped with the lower pressing mechanism for being located at 4 lower section of bearing；
Upper pressing mechanism includes the fixing seat 6 for being fixed on 2 top of rack, is arranged in fixing seat 6 and is located above bearing 4
Upper pressure-applying unit, upper pressure-applying unit includes the top plate 7 positioned at the top of fixing seat 6, is equipped with measuring pen 8, measuring pen among top plate 7
8 bottom ends are connected with upperpush rod 9, and top plate 7 is equipped with upper air cylinder 10, and the piston rod of upper air cylinder 10 is located at admittedly after passing through top plate 7
Above fixed board, upper pressure-applying unit further includes the multiple guide posts 17 for being fixed on 7 bottom of top plate, the guide sleeve 18 covered on guide post 17, consolidates
It is scheduled on 17 bottom of guide post and the upper pressure seat 19 connecting with upperpush rod 9 and the upper spring being arranged between upper pressure seat 19 and guide sleeve 18
20, upper pressure seat 19 is connect with upperpush rod 9 by reed, and 19 bottom end of upper pressure seat has the seaming chuck 1 91 for being located at 4 top of bearing.
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 lower spring 15 that is arranged between limited block 14 and bottom plate 3, linear bearing 214 is installed among down-pressed pole 13, is pushed
13 top of bar has the push-down head 131 for being located at 4 lower section of bearing, and the piston rod top end of return cylinder 11 is equipped with pressing plate 16.
When off working state, the piston rod of upper air cylinder 10 stretches out and withstands fixing seat 6, with constantly stretching for piston rod
Long, top plate 7, guide post 17, upper pressure seat 19 also rise, the compression of upper spring 20, and upper pressure seat 19 is to be detached from 4 outer ring upper surface of bearing
, upperpush rod 9 is to be detached from 4 inner ring upper surface of bearing, and the piston rod of upper air cylinder 10 retracts when work, and upper pressure seat 19 is in upper bullet
The elastic force of spring 20 acts on lower compression axis and holds 4 outer rings, 9 contact bearing of upperpush rod, 4 inner ring, because 4 outer ring of bearing is consolidated by upper pressure seat 19
Fixed, 4 inner ring of bearing has a downward power, and measuring pen 8 measures first numerical value under this state.The piston rod of return cylinder 11
When retraction, pressing plate 16 pushes cross bar 12, and cross bar 12 drives down-pressed pole 13 to move downward, the downward pressing spring of limited block 14, return
When the piston rod of 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, and cross bar 12 is actively set on down-pressed pole 13), the push-down head 131 on 13 top of down-pressed pole relies only on the elastic force of spring
Outer ring is touched, the outer ring of 4 lower end surface of bearing is fixed platform 5 and fixes, and 4 inner ring of bearing is moved up relative to outer ring, this
Under kind state, measuring pen 8 measures second numerical value, and it is exactly radial internal clearance that second of numerical value, which subtracts first time numerical value,.
Certainly, the above is only the preferred embodiments of the present utility model only, and therefore, it does not limit the patents of the utility model
Range, all with the utility model specification and schema content institute, simply modification and equivalent structure change for it, should all similarly wrap
Within scope of patent protection contained in the utility model.
