Abstract
The utility model relates to a device for smoothly assembling an engine real seal. The device comprises a positioning guide block, a guide rod, a sliding clamping ring, a guide sleeve and an installation guide. The positioning guide block is of truncated cone structure, which is provided with a boss on the center of one end face and is connected with one end of the guide rod on the centre of the other end face; the sliding clamping ring is installed on the guide rod in the barrel-type structure via the guide sleeve which is arranged in a through hole at the centre of the bottom of the barrel-type structure, the inside diameter of the barrel-type structure is larger than the outside diameter of the positioning guide block; and the installation guide is arranged on the end of the positioning guide block, which is provided with the boss structure. Compared with the prior art, the device can ensure the precision assembly of the engine real seal and avoid the hidden oil leak trouble caused by the uneven stress borne by the engine real seal or the flanging deformation of different shafts.
Description
Technical field
The utility model relates to the steadily device of assembling of a kind of bent axle Rear oil seal, is used for the bent axle Rear oil seal and steadily assembles, and is easy and simple to handle, effectively guarantees the precision quality of assembling.
Background technology
At present, the apparatus structure that Rear oil seal (having assembled one with the Rear oil seal seat) is fitted into bent axle is simple, also will with the hands directly promote the Rear oil seal seat during installation with the Rear oil seal crankshaft big end of packing into.The main deficiency that this apparatus and method exist is: this device only has simple positioning and guiding effect, with the hands directly contact promotes the Rear oil seal seat, unbalance stress, can not keep level to import installation coaxially, being difficult to guarantee the precision quality requirement of assembling, is the main cause that causes the Rear oil seal oil leakage fault in the assembling process.
Summary of the invention
At the deficiencies in the prior art, this reality has the novel device that a kind of steadily built-up crankshaft Rear oil seal is provided, improves assembly quality.
The utility model bent axle Rear oil seal steadily device of assembling comprises: positioning and guiding piece, guide post, slip trim ring, guide pin bushing and installation guiding; The positioning and guiding piece is a frustum cone structure, and the center of an end face of frustum cone structure is provided with boss, and the center of the frustum cone structure other end is connected with an end of guide post; The slip trim ring is slidingly mounted on the guide post by guide pin bushing, and the slip trim ring is a core structure, in the center through hole guide pin bushing is set at the bottom of the core structure tube, and the core structure cylinder internal diameter is greater than positioning and guiding piece external diameter; Guiding is installed is arranged on the end that the positioning and guiding piece has boss structure.
The utility model bent axle Rear oil seal is steadily in the device of assembling, and the positioning and guiding piece is fixed in an end of guide post by screw attachment, and the other end is provided with back-up ring, and back-up ring carries out spacing to the slip trim ring.Installation is directed to pyramidal structure, and end that the pyramidal structure diameter is big and positioning and guiding piece have an end in contact of boss.The positioning and guiding piece has in the end of boss 2-6 piece magnet is set.
The device that the utility model bent axle Rear oil seal steadily assembles is when the assembling Rear oil seal, finish in two steps: 1. Rear oil seal is gone on the utility model device: by guiding is installed, vertical press-in device to the Rear oil seal inner ring of Rear oil seal assembly (Rear oil seal is formed with the Rear oil seal seat) is contacted with the positioning and guiding piece, the Rear oil seal seat contacts with the slip trim ring, guarantee to locate coaxial, take off then guiding is installed; By the utility model device with the Rear oil seal bent axle of packing into: the boss of positioning and guiding piece connected with the bent axle stomidium cooperate, (frock end face magnet and crankshaft end-face suck, form same axis body), both hands horizontal sliding slip trim ring then, make the slip trim ring slide and act on the Rear oil seal assembly along guide post, the slip trim ring is coaxial parallel, and the Rear oil seal assembly also was seated when stroke finished, and assembling process is finished.
The utility model apparatus and method have following technique effect: the slip trim ring acts on the Rear oil seal assembly by guide pin bushing along the slip of guide post, can make evenly stressed coaxial parallel importing crankshaft big end of Rear oil seal assembly, guarantee the precision of assembling, can effectively avoid in the assembling process being out of shape the leakage of oil hidden danger that produces because of Rear oil seal unbalance stress or flange that disalignment produces.

The specific embodiment
Further specify the steadily device of assembling of the utility model bent axle Rear oil seal below in conjunction with accompanying drawing, and the method for using this device built-up crankshaft Rear oil seal.
As shown in Figure 1, positioning and guiding piece 2 connects by screw 5 with guide post 3, slip trim ring 8 and guide pin bushing 7 interference fit, in the space that back-up ring 6 limits, be free to slide along guide post 3, its stroke and the Rear oil seal crankshaft stroke of packing into is identical, and magnet 4 is provided with 3 uniform being embedded in positioning and guiding piece and the end face that bent axle contacts.
Fig. 2 is the state when Oil sealing assembly being installed going into device, vertically places this device, and Rear oil seal assembly 10 is vertically put into device along guiding 1 is installed, and contact with slip trim ring 8 end faces, and installing leads 1 has tapering, makes simple installation quick.
Fig. 3 is the state when Oil sealing assembly being installed going into bent axle, positioning and guiding piece 2 is positioned in the bent axle stomidium, and three blocks of magnet 4 on it are adsorbed on the crankshaft end-face, both hands horizontal sliding slip trim ring 8, slip trim ring 8 slides along guide post 3 with guide pin bushing 7, promotes the coaxial bent axle 9 of steadily packing into of Rear oil seal.
In the device that the utility model bent axle Rear oil seal steadily assembles, positioning and guiding piece, slip trim ring, installation guiding can use nylon to make, and in light weight, operability is good.
It should be noted that at last: above embodiment only in order to the explanation the utility model and and the described technical scheme of unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technical scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the claim scope of the present utility model.
