Description
Technical field
The present invention relates to a kind of provision for disengagement of bearing outer ring, also relate to its using method simultaneously, belong to frock, technical field of tools.
Background technology
According to the applicant understood, the provision for disengagement of existing counterbore or blind hole bearing primarily of drawing hammer and bolt ejecting type, both structure can respectively see application number be CN201020616454.9, name is called the Chinese patent literature that bearing detaching pull hammer device and application number are CN201010112702.0, name is called a kind of bearing extractor.Usual large diameter bearing outer ring dismounting adopts the latter, 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 the supporting plate, the demolition claw be connected on pressing plate is moved up, thus make bearing outer ring depart from bearing block, realize the dismounting of bearing outer ring.The bearing outer ring disassembling fixture of this class standard can only dismantle a kind of bearing outer ring of model, and when needs have adjustable link, it is reliably safe to be often difficult to due to the mobility of governing loop again to hold, and likely produces accident because of slippage.
Summary of the invention
The object of the invention is to: for above-mentioned prior art Problems existing, propose one and not only there is certain versatility and holding safe reliable bearing outer ring provision for disengagement, thus while guarantee is easy to use, guarantee handling safety.
In order to reach above object, bearing outer ring provision for disengagement of the present invention comprises supporting traverse, described supporting traverse have extend along its length run through chute, described chute forms with it the lockable slider of moving sets built with a pair, and described slide block has the internal thread screwing and eject screw rod; Be set with a pair band forming moving sets with supporting traverse between described two slide blocks and link up with sliding pawl; Positioning templet is clamped between described two sliding pawls.
Its using method is carried out according to the following steps:
Step one, along the chute on supporting traverse, two positioning sliding blocks are adjusted to respectively after position is torn on the top being greater than bearing outer ring external diameter to be removed open and lock; And make the lower end ejecting screw rod in two positioning sliding blocks be supported on top to tear open on position;
Step 2, along supporting traverse, two sliding pawls are adjusted to the position that its hook holds bearing outer ring internal diameter both sides to be removed respectively;
Snap in positioning templet in 3rd step, interval between two sliding pawls, make two sliding pawls keep separated retaining positions;
4th step, screw and eject screw rod in two locked positioning sliding blocks, make it withstand bearing block, make sliding pawl be pulled out by bearing outer ring to be removed, until take apart from the hole of bearing block by hook gradually.
Because positioning sliding block of the present invention and the position that ejects screw rod and sliding pawl all can regulate as required easily, and can respectively by latch-up structure and select suitable positioning templet and relatively fixing, it is reliably safe therefore to hold during dismounting, has both facilitated, again safety.
The present invention further improves, and the apparent surfaces of described two sliding pawls have the inclined-plane forming interval wide at the top and narrow at the bottom, and the cross section of described positioning templet is wide at the top and narrow at the bottom trapezoidal.When positioning templet is snapped in the interval between two sliding pawls by the 3rd step in use, downward pressing positioning templet, thus not only make the hook of two sliding pawls produce the trend of tight axis bearing outer-ring end face, more be conducive to safe dismounting, and the effect at interval can be adjusted by inclined-plane, make same positioning templet be applicable to the bearing outer ring of different size within the specific limits.

Detailed description of the invention
Embodiment one
The bearing outer ring provision for disengagement basic structure of the present embodiment as shown in Figure 1 to Figure 3, have and eject screw rod 7, the supporting traverse 1 of square-section have extend along its length run through chute, chute forms with it the lockable positioning sliding block 3 of moving sets built with a pair, 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.There is in the centre bore of positioning sliding block 3 the vertical internal thread screwing and eject screw rod 7.Be set with a pair band forming moving sets with supporting traverse 1 between two slide blocks 3 and link up with sliding pawl 2.As shown in Figure 2, top has to be moved with supporting traverse the rectangular aperture coordinated and bores a hole the concrete structure of two sliding pawls 2, and lower end has the hook for holding bearing outer ring.Clamp by the band carrying handle positioning templet 6(inserted in supporting traverse 1 chute see Fig. 3,4 between two sliding pawls 2).It can be the bearing block end face of bearing outer ring to be removed or bearing block flange face that position is torn on top open.
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, two slide blocks is adjusted to respectively after the top being greater than bearing outer ring 8 external diameter to be removed tears position open, by nut locking; Along supporting traverse, two sliding pawls are adjusted to the position that its hook holds bearing outer ring internal diameter both sides to be removed respectively again; Snap in positioning templet in interval between two sliding pawls, make two sliding pawls keep separated retaining positions; Screw and eject screw rod 7 in two locked positioning sliding blocks 3, make it withstand the flange of bearing block periphery, make sliding pawl be pulled out by bearing outer ring to be removed, until take apart from the hole of bearing block by hook gradually.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 forming interval wide at the top and narrow at the bottom, positioning templet is wide at the top and narrow at the bottom trapezoidal, and the width of its width and surface groove matches (see Fig. 5).When using the interval snapped in by positioning templet between two sliding pawls, downward pressing positioning templet, the hook of two sliding pawls can be made to produce the trend of tight axis bearing outer-ring end face, more be conducive to safe dismounting, and the effect at interval can be adjusted in inclined-plane, make same positioning templet be applicable to the bearing outer ring of different size within the specific limits.
Facts have proved, the beneficial effect of above-described embodiment is: (1) can by the dismounting regulating positioning templet to realize the bearing outer ring of Multiple Type; (2) torsion ejecting screw rod applies less, facilitates execute-in-place; (3) making of provision for disengagement requires relatively low, reduces the cost of manufacture of provision for disengagement.
