Description
Technical field
The utility model relates to a kind of disassembling fixture, specifically, and particularly a kind of bearing disassembling device.
Background technology
Or retain matrix integrated bearing only has in the bearing chamber that an end is uncovered as some needle bearings or deep groove ball bearing are contained in matrix, owing to there is no enough withdrawal spaces, can only take damage type to remove, and, damages bearing that is:; The damage matrix, retain bearing.With upper type one side disassembling section difficulty, to waste time and energy, operator's labour intensity is large, and removal efficiency is lower; On the other hand, after bearing or matrix dismounting, can not reuse, can greatly increase use cost.
The utility model content
It is a kind of simple to operate that technical problem to be solved in the utility model is to provide, and can not damage the provision for disengagement of matrix or bearing.
The technical solution of the utility model is as follows: a kind of bearing disassembling device, on connecting plate (1), be equipped with two be parallel to each other pull out tappet (2), it is perpendicular with connecting plate (1) that this pulls out tappet (2), be threaded connection two first adjusting hold-down nuts (3) described pulling out on tappet (2), regulated the upper and lower sides that hold-down nuts (3) are held on connecting plate (1) for these two first;
Be provided with mandrel (4) two described pulling out between tappet (2), this mandrel (4) is located in connecting plate (1) middle part perpendicular with connecting plate (1), be threaded connection and extracted nut (5) on the top of described mandrel (4), this extracts the top that nut (5) is placed in connecting plate (1);
Be threaded connection the second adjusting hold-down nut (6) at the middle part of described mandrel (4), this the second adjusting hold-down nut (6) is positioned at the below of connecting plate (1), the bottom of described mandrel (4) has been threaded connection sleeve (7), this sleeve (7) be positioned at the second secured adjusted nut (6) under; The lower end of described mandrel (4) is up big and down small taper tensioner head (4a), this taper tensioner head (4a) is positioned at the circumference that a plurality of wedges (8) surround, described wedge (8) fixes with sleeve (7), and passes through cone match between wedge (8) and taper tensioner head (4a).
Adopt above technical scheme, when only having integrated bearing that an end is uncovered to be dismantled to bearing chamber, at first operating personnel put into wedge the endoporus of bearing, follow down rotation mandrel, mandrel is moved down with respect to sleeve, the taper tensioner head of mandrel lower end is towards circumferentially wedge being pushed, until that wedge and brearing bore fit tightly is swollen dead, then rotating the second secured adjusted nut locks sleeve, pull out tappet by the first two of adjusting hold-down nut adjustment again, two lower ends of pulling out tappet are contacted with matrix phase, after making connecting plate and matrix phase being parallel, hold-down nut is regulated in locking first, finally slowly rotate and extract nut, owing to pulling out tappet and matrix phase supports, connecting plate is pulled out, and tappet is fixing can not be moved down, rotate like this when extracting nut, can produce pulling force upwards to mandrel, making mandrel drive wedge moves up, thereby utilize the tension force of wedge that bearing is extracted.The utility model is simple to operate, laborsaving on the one hand, and operating personnel's labour intensity is little, and removal efficiency is high; On the other hand, the withdrawal force while extracting bearing is evenly mild, can protect bearing and matrix all injury-free, makes bearing and matrix to use by being dismounted for multiple times.
The top of described wedge (8) one that makes progress is extended, and forms the spacer (8a) of circular arc, and this spacer (8a) fits with the outer circumference surface of described sleeve (7), and the screw upwards worn by footpath (9) is fixing.Above structure wedge on the one hand is combined with sleeve closely by spacer, can not shake, in the time of can guaranteeing that wedge is squeezed and the brearing bore swelling; On the other hand, it is firm between wedge and sleeve, to be connected, and mounts and dismounts all very convenient.
For the tension force that makes wedge and brearing bore is enough and evenly, described wedge (8) is 2-4, and is uniformly distributed on circumference.
As preferably, described wedge (8) is made by aluminium alloy, makes wedge more soft on the one hand, when bearing is dismantled, can not cause damage to bearing; On the other hand, aluminium alloy is easy to machine-shaping, can reduce production costs.
Be equipped with boosting-rod (10) in the upper end of described mandrel (4), this boosting-rod (10) is perpendicular with described mandrel (4).By boosting-rod, be with moving mandrel to rotate, convenient and labor-saving.
Beneficial effect: when the utility model is dismantled at the one bearing to being contained in the matrix the inside, can effectively prevent that matrix and bearing are damaged, disassembling section is simple, time saving and energy saving on the one hand, and operator's labour intensity is little, and removal efficiency is high; On the other hand, can guarantee that bearing and matrix can be used by being dismounted for multiple times, have greatly reduced use cost.
