Description
Technical field
The utility model relates to a kind of oilless bearing, especially relates to a kind of oilless bearing dismantling device.
Background technology
Body in white is in the manufacture being welded, weld jig and conveying equipment are the visual plants that vehicle body is manufactured, these equipment are all rotating when operation, its just be unable to do without oilless bearing, because its manufacturing cost is lower, is widely used in the jig arm of weld jig and cuts on the equipment such as beam type suspender, but after these equipment operations for a long time, oilless bearing is wearing and tearing just, thereby cause equipment fault and precision, must change.
The mode of dismounting oilless bearing is to use the instruments such as hammer directly to knock oilless bearing at present, it is exited in installing hole, with hammer, directly knock oilless bearing is carried out to dismounting, waste time and energy and security low, most importantly, while knocking with hammer, the stress surface of oilless bearing is little, can cause oilless bearing discontinuity, thereby affect the installation accuracy of bearing, even cause the damage of oilless bearing.
Chinese patent Granted publication number: CN202006446U, Granted publication day 2011.10.12, a kind of oilless bearing provision for disengagement of oilless bearing for convenience detach is disclosed, it comprises the axle sleeve that oilless bearing is installed, it is characterized in that being provided with in axle sleeve be close to the helping pull a cart of oilless bearing end face, with the bearing pin of helping pull a cart and being connected, the described outside dimension of helping pull a cart is greater than the interior hole dimension of oilless bearing.Its weak point is, this device can only be for the dismounting of oilless bearing, can not be for the installation of oilless bearing, function singleness, simultaneously, this provision for disengagement can only be dismantled the fixedly oilless bearing of inner ring diameter, and versatility is poor, in addition, thereby the principle of this device is the screwing force of nut to be passed to bearing pin by leading screw drive oilless bearing outwards to move, need to be by spanner one circle circle rotating nut, tear that not only to dismantle speed slow open, and effort.
Utility model content
The utility model is that versatility is poor in order to solve the oilless bearing provision for disengagement function singleness of prior art, and dismounting speed is slow, and the problem of effort, provide a kind of easy to use, can to oilless bearing, carry out dismounting fast, and dismounting labour-saving oilless bearing dismantling device.
To achieve these goals, the utility model is by the following technical solutions:
A kind of oilless bearing dismantling device, comprise slide bar and clash into slide block, described shock slide block set is connected on slide bar joins with slide bar cunning, described slide bar front end is fixed with and knocks piece, described in knock piece front end and be fixed with locating shaft, described locating shaft is pre-large post-small multidiameter, cascaded surface on described locating shaft forms ringwise percussion power transfer surface, the external diameter of described percussion power transfer surface is greater than the internal diameter of oilless bearing inner ring, is less than or equal to the external diameter of oilless bearing outer ring, and the rear end of slide bar is provided with block.Shock slide block in the utility model clashes into and knocks piece to produce percussion power, because the external diameter of percussion power transfer surface is greater than the internal diameter of oilless bearing inner ring, be less than or equal to the external diameter of oilless bearing outer ring, after in the dead eye of axle insertion oilless bearing to be positioned, percussion power transfer surface just contacts with the outer face of oilless bearing, clashing into slide block clashes into and knocks the percussion power that piece produces and can act on the outer face of oilless bearing by percussion power transfer surface, thereby oilless bearing is headed into or ejected bearing mounting hole, thereby reach the object of installation or removal oilless bearing.Because percussion power is to transmit by percussion power transfer surface, oilless bearing is stressed evenly, not fragile, and can greatly improve installation accuracy, knock piece generation percussion power simultaneously by clashing into slide block shock, percussion power produces fast, security is good, makes the dismounting of oilless bearing time saving and energy saving, very quick.
As preferably, described in knock piece and be truncated cone-shaped, described in knock the miner diameter end of piece and the bigger diameter end of locating shaft is fixedly connected with.Knock piece and be truncated cone-shaped, be convenient to concentrate shock slide block to clash into and knock the percussion power that piece produces, percussion power can be fully passed on percussion power acting surface, thereby make oilless bearing energy fast assembling-disassembling.
As preferably, the bigger diameter end of described locating shaft is provided with and is fixed with connecting screw rod, and described connecting screw rod is threaded with the miner diameter end that knocks piece.Locating shaft is threaded with knocking piece, is convenient to change the locating shaft of different size so that the utility model adapts to the oilless bearing of different model specification, uses flexibility and versatility good.
As preferably, between described locating shaft and connecting screw rod, be provided with Tool for detaching, described Tool for detaching is regular hexagon, and one end of Tool for detaching is fixedly connected with the bigger diameter end of locating shaft, and the other end is fixedly connected with connecting screw rod.The similar nut of Tool for detaching effect, changes so that pull down locating shaft with instruments such as spanners.
As preferably, described shock slide block is cylindrical.
As preferably, described shock shoe surface is provided with arc-shaped concave in the form of a ring, and described arc-shaped concave forms grip part.Arc-shaped concave is convenient to grasp, and improves comfortableness.
As preferably, the rear end of described slide bar is provided with screw thread, and block and slide bar socket are also fixed on slide bar by clamp nut.Block and slide bar socket are also fixed on slide bar by clamp nut, can change according to the actual requirements the shock slide block of different quality size to produce different active forces.
Therefore, the beneficial effects of the utility model are:
(1) make oilless bearing in disassembly process, stressedly evenly guaranteed that oilless bearing is injury-free in installation process, extended the service life of bearing, the processing safety while simultaneously having improved the installation accuracy of oilless bearing and dismounting;
(2) simple in structure, easy to use, locating shaft that can be by changing different size is to be applicable to the dismounting of different size oilless bearing.
