Description
Technical field
The present invention relates to a kind of provision for disengagement of bearing outer ring, also relate to simultaneously its using method, belong to frock, technical field of tools.
Background technology
Understand according to the applicant, mainly by drawing hammer and bolt ejecting type, both structures can be that CN201020616454.9, name are called bearing detaching pull hammer device and application number is the Chinese patent literature that CN201010112702.0, name are called a kind of bearing extractor referring to application number respectively in the provision for disengagement of existing counterbore or blind hole bearing.The latter is adopted in common large diameter bearing outer ring dismounting, this type of disassembling fixture or instrument are by the end contact of gripper shoe and bearing block, to produce the strong point, then by the bolt down-rotation pushing on pressing plate on gripper shoe, the demolition claw that is connected on pressing plate is moved up, thereby make bearing outer ring break away from bearing block, realize the dismounting of bearing outer ring.The bearing outer ring disassembling fixture of this class standard can only be dismantled a kind of bearing outer ring of model, when needs have adjustable link, often is difficult to hold safe reliable due to the mobility of governing loop again, might produce accident because of slippage.
Summary of the invention
The object of the invention is to: for the problem that above-mentioned prior art exists, proposes a kind ofly not only have certain versatility and holding safe reliable bearing outer ring provision for disengagement, thereby when assurance is easy to use, guarantee handling safety.
In order to reach above purpose, bearing outer ring provision for disengagement of the present invention comprises supporting traverse, described supporting traverse has along its length the chute that runs through that extends, and a pair of lockable slider that forms with it moving sets is housed in described chute, and described slide block has and screws the internal thread that ejects screw rod; Be set with the sliding pawl of a pair of band hook that forms moving sets with supporting traverse between described two slide blocks; Clamp positioning templet between described two sliding pawls.
Its using method is carried out according to the following steps:
Snap in positioning templet in the 3rd step, the interval between two sliding pawls, make two sliding pawls keep the separated position that holds;
The 4th the step, screw the screw rod that ejects in two blocked positioning sliding blocks, make it withstand bearing block, make gradually sliding pawl by the hook bearing outer ring to be removed is pulled out, until take apart from the hole of bearing block.
Due to positioning sliding block of the present invention with eject screw rod and the position of sliding pawl all can be regulated as required easily, and can be respectively by latch-up structure and select suitable positioning templet and relatively fixing, hold when therefore dismantling safe reliable, both convenient, safety again.
The present invention further improves, and the apparent surfaces of described two sliding pawls have the inclined-plane that forms interval wide at the top and narrow at the bottom, and it is wide at the top and narrow at the bottom trapezoidal that the cross section of described positioning templet is.The 3rd step in use is when snapping in interval between two sliding pawls with positioning templet, press positioning templet downwards, thereby the hook that not only makes two sliding pawls produces the trend of tight axis bearing outer-ring end face, more be conducive to safe dismounting, and can adjust the effect at interval by the inclined-plane, make same positioning templet be applicable within the specific limits the bearing outer ring of different size.

The specific embodiment
Embodiment one
The bearing outer ring provision for disengagement basic structure of the present embodiment as shown in Figure 1 to Figure 3, has the screw rod of ejecting 7, the supporting traverse 1 of square-section has the chute that runs through that extends along its length, the a pair of lockable positioning sliding block 3 that forms with it moving sets is housed in chute, the cross section of this positioning sliding block 3 is "T"-shaped, its lower end passes chute, can be locked on supporting traverse 1 by nut 4.Have in the centre bore of positioning sliding block 3 and screw the vertical internal thread that ejects screw rod 7.Be set with the sliding pawl 2 of a pair of band hook that forms moving sets with supporting traverse 1 between two slide blocks 3.The concrete structure of two sliding pawls 2 as shown in Figure 2, top has and supporting traverse rectangular aperture perforation movingly, the lower end has be used to the hook that holds bearing outer ring.Clamp by the band carrying handle positioning templet 6(that inserts in supporting traverse 1 chute referring to Fig. 3,4 between two sliding pawls 2).The top is torn the position open and can be bearing block end face or the bearing block flange face of bearing outer ring to be removed.
During use, the bearing block 7 that bearing outer ring 8 to be pulled down is housed is positioned on workbench, along the chute on supporting traverse, with two slide blocks transfer to respectively tear the position open greater than the top of bearing outer ring 8 external diameters to be removed after, by nut locking; Along supporting traverse, two sliding pawls are transferred to the position that its hook holds respectively bearing outer ring internal diameter to be removed both sides again; Snap in positioning templet in interval between two sliding pawls, make two sliding pawls keep the separated position that holds; Screw and eject screw rod 7 in two blocked positioning sliding blocks 3, make its flange that withstands the bearing block periphery, sliding pawl is pulled out bearing outer ring to be removed by hook, until take apart from the hole of bearing block.When dismantling the bearing outer ring of different size, as long as select suitable positioning templet to adjust the spacing of two slide blocks, very safe convenience.
Embodiment two
The bearing outer ring provision for disengagement basic structure of the present embodiment is identical with embodiment one, difference is that the position of the corresponding positioning templet of apparent surface of two sliding pawls 2 has the surface groove that forms interval wide at the top and narrow at the bottom, it is wide at the top and narrow at the bottom trapezoidal that positioning templet is, the width of its width and surface groove match (referring to Fig. 5).When in use, positioning templet being snapped in the interval between two sliding pawls, press positioning templet downwards, can make the trend of the tight axis bearing outer-ring end face of hook generation of two sliding pawls, more be conducive to safe dismounting, and can the inclined-plane adjust the effect at interval, make same positioning templet be applicable within the specific limits the bearing outer ring of different size.
Facts have proved, the beneficial effect of above-described embodiment is: (1) can realize by regulating positioning templet the dismounting of the bearing outer ring of Multiple Type; (2) torsion that ejects screw rod applies less, facilitates execute-in-place; (3) making of provision for disengagement requires relatively lowly, has reduced the cost of manufacture of provision for disengagement.
