Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
Position as shown in Fig. 4 to Figure 17 can any portable jack shaft ear mounting structure, comprise cylinder barrel 1, protecgulum 2, bonnet 3, axle ear body 4 and pull bar 5, protecgulum 2, bonnet 3 are arranged at the two ends of cylinder barrel 1 respectively, axle ear body 4 is sleeved on cylinder barrel 1 outer wall, pull bar 5 is connected with between protecgulum 2 and bonnet 3, axle ear body 4 can moving axially along pull bar 5, and axle ear body 4 can be fastenedly connected by locked mechanism and pull bar 5 at an arbitrary position.
A kind of position that the utility model provides can any portable jack shaft ear mounting structure, by protecgulum 2 is directly connected by pull bar 5 with bonnet 3, axle ear body 4 can be moved axially along pull bar 5, and by arranging locked mechanism, axle ear body 4 can be fastenedly connected at an arbitrary position with pull bar 5, efficiently solve the changeless drawback in prior art axis ear body 4 mounting point, make using scope of the present utility model more wide; When adjusting the mounting point of axle ear body 4, without the need to dismantling whole cylinder, under the prerequisite ensureing cylinder mass, improve working efficiency greatly; Need to consider that pull bar enters compared with the degree of depth of mounting hole when mounted with traditional jack shaft ear, protecgulum 2 of the present utility model and bonnet 3 are owing to being directly connected by pull bar 5, pull bar 5 meeting through-shaft ear body 4 in assembly process, therefore make the utility model installation procedure less, can greatly enhance productivity, reduce manufacture cost, also effectively ensure that simultaneously the utility model after mounting axle ear body 4 can meet the requirement of perpendicularity.
Embodiment one:
The periphery of axle ear body 4 is as shown in Figures 4 to 7 provided with and has been symmetrical set circular arc part 41 for a pair, the both sides of circular arc part 41 are respectively arranged with first draw-in groove 411 suitable with pull bar 5, locked mechanism comprises the meniscus 61 suitable with circular arc part 41, meniscus 61 is provided with the second draw-in groove 611 matched with the first draw-in groove 411, pull bar 5 is arranged between the first draw-in groove 411 and the second draw-in groove 611, by some lock screw 612 secure fit between axle ear body 4 and meniscus 61.During assembling, along with going deep into of lock screw 612, the distance between the first draw-in groove 411, second draw-in groove 611 and pull bar 5 is more and more less, finally reaches and closely cooperates, thus make axle ear body 4 operationally along the axial dipole field of pull bar 5, the stability of cylinder operation can not be ensure that.When needing to adjust the mounting point of axle ear body 4, only need loosen the lock screw 612 between axle ear body 4 and meniscus 61, just can move axially axle ear body 4 easily, again lock screw 612 being tightened when arriving the mounting point required, completing the adjustment of the mounting point to whole axle ear body 4.In the adjustment process of above-mentioned mounting point, do not need to change pull bar 5 do not need to dismantle whole cylinder yet, greatly reduce the time spent in the process of adjustment axle ear body 4 mounting point, and can not harmful effect be produced to cylinder.In addition, because axle ear body 4 and meniscus 61 can not produce the active force along pull bar 5 axis when mounted, thus effectively reduce axle ear body 4 produces skew phenomenon because of unbalance stress, substantially increase the installation precision of cylinder.
Embodiment two:
Axle ear body 4 as shown in Figs. 8 to 11 is respectively arranged with some with pull bar 5 mounting hole 42 one to one, the mounting groove 421 coaxial with the corresponding mounting hole 42, the diameter of mounting groove 421 is greater than the diameter of mounting hole 42, the outer wall of axle ear body 4 is provided with the screw 422 be communicated with mounting groove 421, locked mechanism comprises the elastic clamping pieces 62 be arranged in mounting groove 421, elastic clamping pieces 62 is sheathed on the outside of corresponding pull bar 5, being provided with in screw 422 offsets with elastic clamping pieces 62 coordinate press solidly screw 621, elastic clamping pieces 62 under the effect pressing solidly screw 621 with pull bar 5 secure fit.When mounted, first elastic clamping pieces 62 is put into corresponding mounting groove 421, afterwards the centre of pull bar 5 from corresponding elastic clamping pieces 62 is passed, behind the mounting point determining axle ear body 4, be screwed into corresponding screw 422 by some screws 621 that presses solidly, along with pressing solidly tightening of screw 621, elastic clamping pieces 62 is because being subject to pressing solidly the impacting force of screw 621 and producing elastic strain, make to produce larger frictional force between pull bar 5 and elastic clamping pieces 62, thus prevent axle ear body 4 from axial dipole field occurring.
As a kind of preferred implementation, see Fig. 9, the opening direction of adjacent two mounting grooves 421 is contrary, is positioned at the opening direction of two mounting grooves 421 of angular direction identical.When cylinder barrel 1 is subject to larger axial force, by arranging said structure, can effectively prevent because pressing solidly between screw 621 with elastic clamping pieces 62 because the situation that elastic clamping pieces 62 is separated with axle ear body 4 occurs not frictional force.
Embodiment three:
The perisporium corner of the axle ear body 4 as shown in Figure 12 to Figure 14 is provided with right-angle notch 43, the joint of two right angle sides of each right-angle notch 43 is provided with first arc surface 431 suitable with pull bar 5, locked mechanism comprises the hornblock 63 with right-angle notch 43 corresponding matching, hornblock 63 is provided with first arc groove 631 corresponding with the first arc surface 431, pull bar 5 is arranged between the first arc surface 431 and the first arc groove 631, and hornblock 63 and axle ear body 4 are by attachment screw 634 secure fit.During installation, first axle ear body 4 is fixed between cylinder barrel 1 and pull bar 5, again four hornblocks 63 are respectively installed to corresponding right-angle notch 43 place, and by attachment screw 634, hornblock 63 is connected with axle ear body 4, along with going deep into of attachment screw 634, axle ear body 4 and hornblock 63 can produce an impacting force to corresponding pull bar 5, make axle ear body 4 and pull bar 5 secure fit.In like manner, when needing the mounting point adjusting axle ear body 4, only need unclamp attachment screw 634 and axle ear body 4 just can be made to move along pull bar 5.
Embodiment four:
The perisporium corner of the axle ear body 4 as shown in Figure 15 to Figure 17 is provided with right-angle notch 43, the joint of two right angle sides of each right-angle notch 43 is provided with second arc groove 432 suitable with pull bar 5, one of them right angle side of right-angle notch 43 is provided with fore shaft 433, locked mechanism comprises the hornblock 63 of right-angle notch 43 corresponding matching, hornblock 63 is respectively arranged with second arc surface 632 corresponding with the second arc groove 432, with the buckle 633 that fore shaft 433 is suitable, pull bar 5 is arranged between the second arc groove 432 and the second arc surface 632, hornblock 63 and axle ear body 4 are by attachment screw 634 secure fit.The present embodiment is identical with the install and adjust mode of embodiment three, distinctive points is: by arranging fore shaft 433 and buckle 633, hornblock 63 can be made higher with the mounting point precision of axle ear body 4, also convenient in installation process, simultaneously according to lever principle, under the mating reaction of snap close and buckle 633, hornblock 63 and axle ear body 4 also can be made can to produce larger impacting force to pull bar 5, fully ensure that axle ear body 4 Security in use.
The above is only better embodiment of the present utility model, therefore all equivalences done according to structure, feature and the principle described in the utility model patent claim change or modify, and are included in the utility model patent claim.
