Abstract
The utility model discloses an Installing device for airplane wheel bearing cup. The bearing cup installing device using for the airplane wheels comprises a hydraulic system, a hydraulic head (4) fixed on a rack (2), a worktable (1), a hub inner diameter (8) and a bearing cup (7). The bearing cup installing device using for the airplane wheels is characterized in that a bearing cup installing device is arranged under the hydraulic head (4). The bearing cup installing device comprises a base seat (9) and a stamper (6). The base seat (9) is fixedly connected with the worktable (1). The bearing cup installing device using for the airplane wheels has the advantages that traditional manual operation is changed, labor intensity and damage of the bearing cup are reduced and function is improved. Quality controlling of a traditional bearing cup installation is relied on experience of workers and is not beneficial to standardized management. According to the installation device for the airplane wheel bearing cup, a hydraulic device is used for pressurizing and the pressure is controllable and adjustable. Therefore, working efficiency is improved, cost is saved and usage is convenient.
Description
Technical field
The utility model relates to the technical field of flight-line maintenance, especially relates to the erecting device of machine repairing benchwork when maintenance airplane wheel bearing cup is changed.
Background technology
Along with the development of society and the raising of people's living standard, aircraft provides conveniently service to us, first-selections that we go on a journey as the vehicles, wheel is the important parts of aircraft, but along with the continuous use of wheel, it is loosening, overheated that load mould, scaling, burn in use can appear in the wheel bearing cup, distortion etc. phenomenon, affect the normal use of wheel, need to change bearing cup.Prior art is by pincers worker manual operations, and not only efficient is low but also can what cause in various degree infringement to bearing cup because of people's working experience, and this is the deficiencies in the prior art.
Summary of the invention
The purpose of this utility model is to improve the shortcoming that exists in the prior art, provide a kind of volume little, simple in structure, that gets rid of that Humanistic Factors disturbs is used for airplane wheel bearing cup erecting device, it has changed traditional manual operations, reached the purpose of applications well, the technical scheme that adopts is: be used for airplane wheel bearing cup erecting device, comprise hydraulic system, be fixed on the fluid head that frame adds, workbench, bearing cup is characterized in that: the bearing cup erecting device is set below described fluid head, described bearing cup erecting device comprises base and pressing mold, and described base and described workbench are connected.
Technical characterictic of the present utility model also has: an end of described pressing mold is cylinder, the other end is cone, described cylindrical end face places the below of described fluid head, and described cone places described bearing cup inner ring, and the tapering of described cone is consistent with the tapering of described bearing cup inner ring.
Technical characterictic of the present utility model also has: an end of described base is cylinder, and the other end arranges cylinder boss, and described cylinder boss places described wheel hub internal diameter, and the diameter of described cylinder boss is less than described wheel hub internal diameter.
Technical characterictic of the present utility model also has: the height of described cylinder boss is greater than the axial length of described wheel hub internal diameter.
The beneficial effects of the utility model are:
1) changed traditional manual operations, alleviated workman's labour intensity and to the infringement of bearing cup, improved effect;
2) quality control of traditional bearing cup installation with workman's experience, is unfavorable for standardized management entirely;
3) this programme be used for airplane wheel bearing cup erecting device, utilize hydraulic means to pressurize, and pressure is controlled, adjustable, has improved operating efficiency, has advantage with low cost, easy-to-use.
Description of drawings
Accompanying drawing 1 is that accompanying drawing 2 is the utility model structural representations for airplane wheel bearing cup erecting device structural representation, wherein, the 1st, workbench, the 2nd, frame, the 3rd, wheel, the 4th, fluid head, the 5th, hydraulic pump, the 6th, pressing mold, the 7th, bearing cup, the 8th, wheel hub internal diameter, the 9th, base, the 10th, cylinder boss.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is specifically described.
Be used for airplane wheel bearing cup erecting device in the utility model, comprise hydraulic system, be fixed on fluid head 4, workbench 1, wheel hub internal diameter 8, bearing cup 7 on the frame 2, it is characterized in that: the bearing cup erecting device is set below fluid head 4, described bearing cup erecting device comprises base 9 and pressing mold 6, and base 9 is connected with described workbench 1.One end of pressing mold 6 is cylinder, and the other end is cone, and cylindrical end face places the below of fluid head 4, and cone places bearing cup 7 inner rings, and the tapering of cone is consistent with the tapering of bearing cup 7 inner rings.One end of base 9 is cylinder, and the other end arranges cylinder boss (10), and cylinder boss 10 places wheel hub internal diameter 8, and the diameter of cylinder boss 10 is less than wheel hub internal diameter 8.The height of cylinder boss 10 is greater than the axial length of wheel hub internal diameter 8.
During concrete the installation, also to take some ancillary methods, wheel hub be put into baking box carry out heat treated.110 ℃ of temperature were toasted 10-15 minute.New bearing cup is put into liquid nitrogen, about 10 minutes, wheel hub is taken out from baking box on the placement hydraulic press, the bearing cup mounting tool is in place.The new bearing that cooling is good is put into bearing mounting hole, begins pressurization.
Certainly; above-mentioned explanation is not limitation of the utility model; the utility model also is not limited only to above-mentioned giving an example, and the variation that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement also belong to protection domain of the present utility model.
