Summary of the invention
For the problems referred to above, the invention provides a kind of structure simple, easy accessibility, save the bearing holder (housing, cover) swelling fixture of material.
Realize technical scheme of the present invention
Bearing holder (housing, cover) swelling fixture, comprise oil cylinder, piston, large pull bar, lower link bar and clamp body, piston is arranged in oil cylinder, piston is connected with large pull bar, large pull bar is connected with lower link bar, clamp body is sleeved on large pull bar and lower link bar, described clamp body comprises counter flange, supporting mass, movable cone seat, positioning body, expansion block, La Sai dish, some springs and adapter sleeve, described expansion block is hexaploid, supporting mass is connected with on the right side of described counter flange, positioning body is provided with on the right side of supporting mass, movable cone seat is had in positioning body inside, movable cone seat and supporting mass are connected by screw, described activity cone seat outer cover is equipped with expansion block, expansion block is close to movable cone seat by holding tightly under the effect of spring, and be distributed on movable cone seat surrounding, be provided with on the right side of described expansion block and draw plug dish, La Sai dish is made up of the boss on disk and disk, upper and lower two ends and expansion block right contact on the left of described disk, boss on disk is arranged in the installing hole of movable cone seat inside, and equal diameters, described drawing on the right side of plug dish is provided with adapter sleeve.
Described spring is three.
Described large pull bar and lower link bar are threaded connection, and large back end of tie rod offers thread groove, and lower link bar front end is provided with the screw thread matched with thread groove
Adopt such scheme, when expansion shaft bearing sleeve, hydraulic oil cylinder driving piston to left movement, thus drives large pull bar, lower link bar, adapter sleeve and La Sai dish to be moved to the left, and six lobes drawing plug dish to promote expansion block are left on activity cone seat while movement, six outside distendings of lobe of expansion block, thus swelling bearing axle sleeve, when unclamp bearing holder (housing, cover), above-mentioned each an ancient unit of weight moves right, six lobes of expansion block shrink, and unclamp bearing holder (housing, cover).
By the detailed description below in conjunction with accompanying drawing, aforesaid and other object, the feature and advantage of the present invention will become apparent.Wherein:
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
As shown in the figure, bearing holder (housing, cover) swelling fixture, comprise oil cylinder 1, piston 2, large pull bar 3, lower link bar 4 and clamp body, piston 2 is arranged in oil cylinder 1, piston 2 is connected with large pull bar 3, large pull bar 3 is connected with lower link bar 4, clamp body is sleeved on large pull bar 3 with on lower link bar 4, clamp body comprises counter flange 5, supporting mass 6, movable cone seat 7, positioning body 8, expansion block 9, La Sai dish 10, some springs 11 and adapter sleeve 12, expansion block 9 is hexaploid, movable cone on seat can move freely not self-locking again, supporting mass 6 is connected with on the right side of counter flange 5, positioning body 8 is provided with on the right side of supporting mass 6, the size of restraint cone seat 7, and restriction expansion block 9 is along the distance of activity cone seat 7 movement, movable cone seat 7 is had in positioning body 8 inside, movable cone seat 7 is connected by screw 13 with supporting mass 6, improve the stability connected, movable cone seat 7 outer cover is equipped with expansion block 9, hold tightly under the effect of expansion block 9 by spring 11 and be close to movable cone seat 7, and be distributed on movable cone seat 7 surrounding, be provided with on the right side of expansion block and draw plug dish 10, La Sai dish 10 is made up of the boss on disk and disk, upper and lower two ends and expansion block 9 right contact on the left of disk, boss on disk is arranged in the installing hole of movable cone seat 7 inside, and equal diameters, adapter sleeve 12 is provided with on the right side of La Sai dish 10, prevent from drawing plug dish 10 to come off from lower link bar, during expansion shaft bearing sleeve 14, oil cylinder 1 driven plunger 2 is to left movement, thus drive large pull bar 3, lower link bar 4, adapter sleeve 12 and La Sai dish 10 are moved to the left, six lobes that La Sai dish 10 promotes expansion block 9 are left on activity cone seat 7 while movement, six outside distendings of lobe of expansion block 9, thus swelling bearing axle sleeve 14, when unclamping bearing holder (housing, cover) 14, above-mentioned each an ancient unit of weight moves right, six lobes of expansion block 9 shrink, unclamp bearing holder (housing, cover) 14.
Preferably, spring 11 is three, makes expansion block 9 bore seat 7 with activity and is more close to, improve the serviceability of bearing holder (housing, cover) swelling fixture.
Further, large pull bar 3 is threaded connection with lower link bar 4, and large pull bar 3 rear end offers thread groove, and lower link bar 4 front end is provided with the screw thread matched with thread groove, improves large pull bar 3 and the stability be connected between lower link bar 4.
The present invention is not limited to described embodiment, and those skilled in the art, not departing from spirit of the present invention namely openly in scope, still can do some and revise or change, therefore the scope that the scope of the present invention limits with claims is as the criterion.
