Description
Technical field:
The utility model relates to a kind of instrument of dismantling lorry axle head bolt, especially a kind of with unscrew machine and cooperate the special use of dismounting railway freight-car axle head bolt to pull cover.
Background technology:
Original dismounting lorry axle head bolt pull the cover be that six sides pull cover, since with can not rotational angle after turret head cooperates, pull cover and work simultaneously for three during dismounting axle head bolt, contraposition is extremely inconvenient, and it is less with bolt six side's fit clearances to pull cover simultaneously, is being equipped with under the situation of locking pad, pulling cover stretches into less than the bottom, it is not in place to be installed, and is easy to skid, and removal efficiency is low.
The utility model content:
The utility model provides a kind of special use that is used to dismantle railway freight-car axle head bolt to pull cover, it is rational in infrastructure, it is accurately convenient to pull cover front end and bolt contraposition, be installed and put in place, non-slip, pull the cover rear end and unscrew machine and cooperate, speed is fast during assembling-disassembling bolt, the efficient height has solved problems of the prior art.
The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be: it comprises pulls the cover body, pull the cover body in by after be provided with setting circle, cubic hole and arc groove forward successively, in the plectane groove, along the circumferential direction evenly be provided with three plum blossom claws, be provided with chamfering by pulling the cover body edges at the front end of each plum blossom claw; Be provided with locating hole in the position of pulling corresponding cubic hole on the cover body, the position of corresponding locating hole is provided with annular groove outside pulling the cover body.
The utility model is provided with three plum blossom claws in the arc groove of pulling cover body front end, can make things convenient for accurately that the contraposition cover installs on the turret head, and the cover of pulling that cover installs can left rotation and right rotation, simultaneously the part of turning up of locking pad is inserted in together during suit, so just carry-over moment effectively prevents to skid; The chamfering that plum blossom claw front end is provided with can make the fit clearance between plum blossom claw and the bolt bigger, more helps the contraposition that once is installed; To pull the cover rear end and unscrew machine and cooperate, and can make assembling-disassembling bolt speed faster, increase work efficiency greatly.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A sectional structure schematic diagram among Fig. 1.
Among the figure, 1, pull the cover body; 2, setting circle; 3, cubic hole; 4, arc groove; 5, plum blossom claw; 6, chamfering; 7, locating hole; 8, annular groove.
The specific embodiment:
For clearly demonstrating the technical characterstic of this programme, below by the specific embodiment, and in conjunction with its accompanying drawing, the utility model is elaborated.
Shown in Fig. 1～2, the utility model comprises pulls cover body 1, pull the cover body 1 in by after be provided with setting circle 2, cubic hole 3 and arc groove 4 forward successively, in plectane groove 4, along the circumferential direction evenly be provided with three plum blossom claws 5, be provided with chamfering 6 by pulling cover body 1 edge at the front end of each plum blossom claw 5; The position in corresponding cubic hole 3 is provided with locating hole 7 on the cover body 1 pulling, and the position of corresponding locating hole 7 is provided with annular groove 8 pulling cover body 1 outside.
During use, install to and unscrew the pulling on the axle of machine pulling cubic hole 3 covers of cover on the body 1, and by setting circle 2 location, insert bearing pin for 7 li at locating hole, and overlap a sealing ring 8 li of annular grooves and fix, to pull the part of turning up of being inserted in axle head bolt and locking pad in the arc groove 4 of cover body 1 front end again, the front end face of pulling cover body 1 is contacted with the end cap end face of lorry axle, and being installed puts in place, rotates this moment and unscrews machine, plum blossom claw 5 contacts with outer six sides of axle head bolt, bolt is accepted moment, then the axle head bolt can be unscrewed, and simultaneously steel wire is broken, until withdrawing from the axle head bolt, work finishes.
The utility model does not describe part in detail, is those skilled in the art of the present technique's known technology.
