Description

The shock-absorber cylinder drilling-milling clamper
Technical field
The utility model relates to the clamp technology field, especially relates to tube drilling-milling clamper at the bottom of a kind of motorcycle vibration absorber.
Background technology
In order to relax impact and the vibrations that receive because of road is rough and uneven in surface in the process of moving with the decay motorcycle, guarantee the ride comfort and the comfortableness of driving, help improving the service life of motorcycle and the stability of manipulation, be provided with dampening arrangement on the motorcycle.End tube is an important component part of damper; And be a difficult point at present to the processing of end tube; Dual mode is generally adopted in the processing of end tube at present: one is that two ends hold out against and adopt other supplemental support mode; This mode is processed the end during tube, and weak point is that machining accuracy end tube adjustment supplemental support not high, that change different cultivars is cumbersome, thereby is not suitable for the tube processing of many kinds end; Another one is to adopt internal expanding axle mode, and this kind mode is adjusted simple relatively, but needs before the processing earlier with apotting spindle of every end wound packages, and labour intensity greatly or need other people to assist like this.
The utility model content
The utility model technical problem to be solved is to provide a kind of processing location that can effectively realize end tube, the shock-absorber cylinder drilling-milling clamper of novelty simple in structure.
The technical scheme of the utility model is following: a kind of shock-absorber cylinder drilling-milling clamper, and its main points are: comprise base plate, on this base plate, be fixed with hold-down support; On this hold-down support, be fixed with apotting spindle and corner oil cylinder; The piston rod of said corner oil cylinder stretches out said hold-down support, and the piston rod external part of this corner oil cylinder is connected with pull bar, and said pull bar and apotting spindle laterally arrange; And this pull bar and apotting spindle are positioned at the same side of said hold-down support; Outer end at said pull bar is fixed with pressing plate, on this pressing plate, is fixed with pressure head, and the outer end of this pressure head and said apotting spindle is over against setting.Adopt above structure, the utility model is installed on the lathe, then end jacket casing is contained on the above-mentioned apotting spindle; Start the corner oil cylinder, under the effect of corner oil cylinder, the piston rod of this corner oil cylinder pulling pull bar; Make pull bar pulling pressing plate tube at the bottom of workpiece move; So tube at the bottom of the realization pressure head workpiece pressing at this moment, can bore end tube and mill; After end tube machines, start the corner oil cylinder, make its rotation, come thereby pressing plate dodged with pressure head and end tube, the end tube that can will process this moment takes off, and changes the end tube that needs processing again, and like this circulation gets final product.In the above structure, can according to different size in other words the end tube in aperture change apotting spindle, so can realize that the brill of tube mills processing at the bottom of the different model, the scope of application increases greatly.In the said structure, workpiece is sleeved on the apotting spindle, adopts the endoporus location, make the design of machining benchmark and workpiece unified, reduced the benchmark transmission error.
On said base plate, sliding support is installed, be enclosed within on the said pull bar outside this sliding support top, and this sliding support is between said hold-down support and pressing plate.Adopt above structure,,, finally realized the reliable clamping and positioning of tube at the bottom of the workpiece so increased the stability of pull bar because the existence of sliding support is played the effect of a support to pull bar.
Said apotting spindle is two; Two these apotting spindle secured in parallel are on said hold-down support; And two these apotting spindles are symmetricly set on the both sides of said corner oil cylinder, on said pressing plate, all be fixed with the outer end of two said apotting spindles over against said pressure head.Adopt above structure, can realize the processing of tube at the bottom of two has been improved operating efficiency.
On said base plate, be fixed with the cylinder positioning support, this cylinder positioning support is between said apotting spindle and pressure head, and this cylinder positioning support is positioned at the extended line below of said apotting spindle.Adopt above structure; At the bottom of cover is loaded onto workpiece on apotting spindle during tube; The cylinder piston rod of cylinder positioning support moves upward, and its upper end can be carried out a support to the part plan of tube at the bottom of the workpiece, thereby can be good at guaranteeing the location of workpiece rotation direction; Utilize the cylinder stroke to reduce supplemental support, easy to adjust when using simultaneously.
On said apotting spindle, be installed with back-up ring, said hold-down support is close in a side of this back-up ring, and the another side is provided with annular knurl; The outer end of said pressure head and said apotting spindle over against an end face on be provided with annular knurl.Adopt above structure; When jacket casing at the bottom of the workpiece is contained in when processing on the apotting spindle because back-up ring all is provided with annular knurl with the side that pressure head contacts with workpiece, increased like this and workpiece between coefficient of friction; And the normal pressure that provides through the corner oil cylinder; Its frictional force that provides is enough to the balance workpiece and mills the cutting force that receives in the process at brill, adopts supplemental support to compare with frock in the past and reduces adjustment, clamping time, simplified operation.
Beneficial effect: the employing of the utility model can adapt to that the brill of tube mills processing at the bottom of the various models, adds to adopt the endoporus location man-hour, has reduced the benchmark transmission error; The utlity model has simple in structure, characteristics such as working (machining) efficiency is high, machining accuracy height.
