Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is structural representation of the present invention.
The specific embodiment
Below in conjunction with specific embodiment and accompanying drawing, further describe the present invention.
A kind of cross axle press-loading apparatus as described in Figure 1, it comprises the pressure head 2 that piston rod 1 and end thereof connect, between described piston rod 1 and pressure head 2, be provided with joint 3, these joint 3 inner hollow, wherein, described piston rod 1, pressure head 2 correspondences are connected with joint 3 two ends, and elasticity is provided with and compresses pin 7 in joint 3 and on the sidewall of this joint 3 described in described pressure head 2 partial insertions, and the location circular groove on this compressions pin 7 and described pressure head 2 outer walls leans.
Cross axle in the present invention press-fits employing piston as power, by 2 pairs of cross axles of pressure head, press-fits.In press-fiting process, by adjusting, compress the elastic force of pin 7 on the circular groove of location, so that the force of sliding friction between pressure head 2 and joint 3 obtains constant, also the force of sliding friction that can be described as pressure head 2 and compress between pin 7 obtains constant, when press-fiting pressure when excessive, while that is to say that press-fiting pressure is greater than pressure head 2 and compresses the force of sliding friction between pin 7, pressure head 2 moves up and produces elastic pressure to compressing pin 7, like this, having avoided the excessive cross axle shot that cross axle is press-fited of pressure head 2 pressure to produce damages, protected cross axle shot, and increase work efficiency, reduce labour intensity, save assembly cost.And be conducive to the integral installation of follow-up power transmission shaft, saved the integral installation time.For the cross axle of different sizes, can to realize, the cross axle of different sizes be press-fited by changing the pressure head 2 of different size, guarantee being normally pressed into of cross axle shot, avoid occurring damaging by pressure or pressing the situation less than cross axle shot.In addition, after pressure head 2 weares and teares, only need to change this pressure head 2, demolition and maintenance are convenient and swift.
When making the pressure of pressure head 2 excessive, can move up and produce elastic pressure to compressing pin 7, in other words, when the pressure of pressure head 2 is excessive, compressing pin 7 can move relative to described location circular groove, and described location circular groove is preferably to spherical arc shape or taper, certainly, also can be other shape, such as arc groove etc.
On the sidewall of described joint 3, along it, be radially provided with through hole, the through hole end of described compression pin 7 in described joint 3, at the through hole end screw thread on joint 3 outer walls, be provided with trip bolt 5, at this trip bolt 5, to compressing between pin 7, establish spring 6, by regulating the position of trip bolt 5 in through hole, with Compress Spring 6, and then regulate the pressure of compression pin 7 in the circular groove of location.In order to guarantee normal use and the service life of spring, on the end face between trip bolt 5 and compression pin 7, be provided with round platform, described both ends of the spring correspondence is positioned this trip bolt 5, compresses on the round platform of pin 7.
By described through hole, be two or four, on the one hand, can improve the pressure adjusting that compresses pin 7, on the other hand, by the setting of two or four through hole, make the 7 pairs of pressure heads 2 of compression pin in it realize pressure balance, avoid in press-fiting process the pressure transient of pressure head 2 and cause press-fiting failure.
At the through hole end in described joint 3, establish interior step, described compression pin 7 is multidiameter, and the shaft shoulder portion of this compression pin 7 and the interior step shoulder of described joint 3 lean and compress pin 7 ends in described joint 3 hollow channels.By the interior step in through hole, arrange, the assemble sequence of pressure head 2, alignment pin 7, joint 3 is not interfered mutually, when assembling, can first assemble pressure head 2 and joint 3, by alignment pin 7 fit ons, also can first assemble alignment pin 7 and joint 3 again, then by pressure head 2 fit ons, in a word, reduced the assembly difficulty of equipment.
Described pressure head 2 is multidiameter, and wherein, described location circular groove to the distance of its adjacent pressure head 2 shaft shoulder portions is greater than compression pin 7 on described joint 3 to the distance between the end face of these joint 3 pressure head of installing 2 ends.For pressure head 2 pressure are when excessive, move up mobile space is provided, avoid the movement because of the distance affects pressure head 2 between the multidiameter shoulder of pressure head 2 and the end face of joint 3 pressure head of installing 2 ends.
And the hollow channel of described joint 3 is interior step shape, wherein, in this joint of described piston rod 1 partial insertion 3 and be connected by pin 4.
The technical scheme above embodiment of the present invention being provided is described in detail, applied specific case herein the principle of the embodiment of the present invention and embodiment are set forth, the explanation of above embodiment is only applicable to help to understand the principle of the embodiment of the present invention; , for one of ordinary skill in the art, according to the embodiment of the present invention, in the specific embodiment and range of application, all will change, in sum, this description should not be construed as limitation of the present invention meanwhile.
