Technical field
The utility model relates to engineering mechanical maintenance maintenance technical field.
Background technology
During the bearing that between the final transmission device axle of dismounting tracked construction equipment and wheel hub, cooperates, traditional method is to use copper rod and sledgehammer to install, and such installation method is not only wasted time and energy, and also is easy to damage bearing and associated components, inefficiency.
The utility model content
The utility model technical problem to be solved provides engineering machinery hub bearing tool specially for attaching and detaching, and is time saving and energy saving, prevents that effectively mechanical shock from damaging bearing and associated components, promotes efficient.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is: a kind of engineering machinery hub bearing tool specially for attaching and detaching comprises hydraulic cylinder, adjustment cover, adjustment folder, baffle plate, pull bar and guide post; Said adjustment cover is fixedly connected with the hydraulic cylinder body head end, and said pull bar is fixedly connected with the piston rod end of hydraulic cylinder and overlaps coaxial setting with said adjustment; Said adjustment folder is rectangular structure, and the center is provided with screwed hole, two ends be provided with outwardly open slotted eye and the slotted eye axis direction identical with said screwed hole axis direction, the adjustment folder with adjust external threading and be connected; Said baffle plate is that discoideus structure and center are fixedly connected with said pull bar; Said guide post comprises two, and two guide posts insert in the slotted eye at adjustment folder two ends respectively and guide post passes the adjustment folder near the supporting nut that is provided with of an end of hydraulic cylinder.
Said adjustment cover is threaded with the hydraulic cylinder body head end.
Adopt the beneficial effect that technique scheme produced to be: to use the engineering machinery hub bearing tool specially for attaching and detaching dismounting hub bearing that the utility model disclosed; Advance or pull out hub bearing with the Driven by Hydraulic Cylinder baffle plate; Prevent that effectively mechanical shock from damaging bearing and other parts, improve engineering machinery hub bearing maintenance efficient greatly.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Fig. 1 is the utility model structural representation;
In the accompanying drawings: 1, hydraulic cylinder; 2, adjustment cover; 3, adjustment folder; 4, piston rod; 5, pull bar; 6, guide post; 7, baffle plate.
The specific embodiment
A kind of engineering machinery hub bearing tool specially for attaching and detaching as shown in Figure 1 comprises hydraulic cylinder 1, adjustment cover 2, adjustment folder 3, baffle plate 7, pull bar 5 and guide post 6; Said adjustment cover 2 is fixedly connected with hydraulic cylinder 1 cylinder body head end, and said pull bar 5 is fixedly connected with piston rod 4 ends of hydraulic cylinder 1 and overlaps 2 coaxial settings with said adjustment; Said adjustment folder 3 be a rectangular structure, and the center is provided with screwed hole, two ends be provided with outwardly open slotted eye and the slotted eye axis direction identical with said screwed hole axis direction, adjustment folder 3 overlaps 2 and is threaded with adjusting; Said baffle plate 7 is that discoideus structure and center are fixedly connected with said pull bar 5; Said guide post 6 comprises two, and two guide posts 6 insert in the slotted eye at adjustment folder 3 two ends respectively and guide post 6 passes adjustment folder 3 near the supporting nut that is provided with of an end of hydraulic cylinder 1.
Said adjustment cover 2 is threaded with hydraulic cylinder 1 cylinder body head end.
In concrete application process, the wheel hub that at first will have bearing is placed on the support, keeps axis horizontal; Support can adopt the angle bar frame that uses in the common machine maintenance work, and two guide post symmetries are screwed into the screwed hole of wheel hub outer end, will adjust cover then and be fixedly connected with cylinder ends; Secondly will adjust to press from both sides to be screwed in to adjust and put; Pull bar is connected with the piston rod end, and the pull bar open end is being threaded with baffle plate, in actual production process, can also step be set in baffle plate one side; The diameter of step and bearing bore diameter are to adaptive, and the distance adjustment adjustment that press-fits according to bearing simultaneously is clipped in the relative position that adjustment puts; Once more, with the step of the baffle plate brearing bore of suiting the medicine to the illness, simultaneously with the other end of two guide posts respectively symmetry be installed in the slotted eye at adjustment folder two ends, tighten its end bolt; Be connected with oil pipe between hand oil pump and the hydraulic cylinder at last, the reversal valve position according to piston direction of motion adjustment hand oil pump presses hand oil pump control crank fuel feeding; Hydraulic cylinder piston promotes pull bar and baffle plate motion; Thereby bearing press mounting is put in place, confirm that bearing press mounting puts in place after, answer repercussion to pull the switching-over valve rod; Make the hydraulic cylinder counter motion, pull down parts such as adjustment folder, adjustment cover, guide post subsequently; Dismounting bearing process and installation process are basic identical, and difference is that baffle plate should be installed in the other side of bearing, is that the Driven by Hydraulic Cylinder baffle plate is pulled outwardly bearing; The utility model is realized bearing dismantling through using the combination of Driven by Hydraulic Cylinder rod member; Abandon existing copper rod and sledgehammer installation and removal method; The infringement of effectively avoiding mechanical shock that bearing and other parts are brought improves operating efficiency, shortens engineering mechanical maintenance maintenance period.
