Description
Technical field
This utility model belongs to axle sleeve field of fixation devices, particularly relates to a kind of fixing device for ladder axle sleeve。
Background technology
Automobile has become as people and lives the indispensable vehicles, universal along with automobile, and the prescription of automobile is also more and more higher。And the quality of automobile mainly embodies from all kinds of spare and accessory parts of automobile, except the accessory that electromotor is so important, some little part qualities are also very important。Having the part of a lot of ladder shaft sleeves on one automobile, this kind of part generally requires in process of production and it is fixed, and then carries out other processing。
Inside current factory, the fixing of this kind of part mainly being clamped with scroll chuck, there is problems of, scroll chuck is entirely manual operations in clamping process, and process is comparatively laborious so that fixed speed is very slow；Use scroll chuck clamps, and holds imprudence in too tight or clamping and all can make the outer wall scratch of ladder shaft sleeve parts, causes the damage of part。
It is thus desirable to a kind of device that the lossless evil idea of ladder axle sleeve can also quickly be fixed。
Utility model content
This utility model provides a kind of fixing device for ladder axle sleeve, the loaded down with trivial details slow-footed problem of fixation procedure to solve ladder axle sleeve。
In order to achieve the above object, base case of the present utility model is: for the device that ladder axle sleeve is fixing, including pressing plate, base, lever, pull bar, gear and power source；Power source is coaxially connected with gear, can rotate by driven gear, is installed on the inside of base；Pull bar and base are slidably connected, and its upper end is provided with the kayser of ladder shaft-like, and pull bar is provided with the rack pinion rotation engaged with gear can make pull bar slide；Pressing plate one end and lever are rotationally connected, and this end is provided with handle, is used for shaking pressing plate, and the other end is provided with the draw-in groove being connected with snap fit；Lever and base are slidably connected。
The principle of this base case is in that: ladder axle sleeve is enclosed within pull bar from pull bar upper end, and swinging handle makes the draw-in groove on pressing plate sealed with the kayser on pull bar。Power source starts makes pinion rotation, pulls pull bar to slide to base direction。Pressing plate and base are by ladder axle sleeve clamping。While pull bar moves to base direction, because pull bar has driven pressing plate, the lever being connected with pressing plate also can be moved to base direction therewith。
Having the beneficial effects that of this base case: power source makes pinion rotation band carry-over bar move, and pull bar slides therewith, so arranges and pull bar quick and stable can be made to slide。Lever limits the slewing area of pressing plate, makes the draw-in groove energy on pressing plate quickly and snap fit。When fixed step axle sleeve, being put up by ladder axle sleeve, swinging handle and startup power source, operating process is also very simple。This device is to overlap axial end fixed step axle sleeve by both sides multidiameter, it is to avoid ladder sleeve outer surface is caused damage。Compared with existing scroll chuck fixed step axle sleeve, simplify ladder axle sleeve fixation procedure, improve the speed that ladder axle sleeve is fixing。It also avoid in fixing and ladder sleeve outer surface is caused damage。
Scheme two: based on scheme preferred, lever and pressing plate junction are provided with the alignment pin for fixing both。Pressing plate itself can rotate around lever, and in fixed step axle sleeve process, alignment pin is easy to restriction pressing plate and is rotated along lever, it is prevented that when ladder axle sleeve is fixing, pressing plate rocks。
Scheme three: based on scheme another preferably, one end that lever is connected with base is provided with back-up ring。Lever and base are to be slidably connected, and the anti-arresting lever of back-up ring slips from base。
Scheme four: based on scheme another preferably, the first banking pin is installed in the position that described lever is provided with the first stopper slot, base and the first stopper slot corresponding。Lever and base are to be slidably connected, and the first stopper slot and the first banking pin are for limiting the displacement of lever and base relative sliding。
Scheme five: based on scheme another preferably, the second banking pin is installed in the position that pull bar is provided with the second stopper slot, base and the second stopper slot corresponding。Pull bar and base are to be slidably connected, and the second stopper slot and the second banking pin are for limiting the distance of pull bar and base relative sliding。
Scheme six: based on scheme another preferably, dismountable on described base be provided with the chuck coordinated with pressing plate。Base is a big entirety, in ladder bearing fixation procedure, it is difficult to avoid making contact surface abrasion。Chuck can avoid direct when ladder axle sleeve is fixed and base contacts, makes seat wear。
Scheme seven: preferred as scheme six, chuck with base with threadeding。In device use procedure, chuck and base need to link into an integrated entity。With threaded, the fixtures such as screws bolts can be used, make stable connection, be convenient to when dismounting。
Scheme eight: based on preferred to any one of scheme seven of scheme, base is connected one end with lever and arranges shaft-cup。In order to facilitate the installation of lever, the axis hole that base is connected with lever is a through hole, and axis hole may be used for the dust-proof of device and seals。
