Description
Technical field:
The utility model relates to a kind of aircraft industry airplane component removal tool, and particularly a kind of helicopter landing gear damper leg upper support decomposes instrument.
Background technology:
The undercarriage damper leg adopts two-cylinder type oil gas formula buffer unit; Be used for reducing the impact that helicopter is born under touchdown and ground taxi process alternate load state; And weaken aircraft and beat because of jolting of causing of bump, nearly 70% the kinetic energy of landinging impact can absorb and dissipate.In the course of work of compression of undercarriage damper leg and stretching, extension; The piston section of cylinder-piston assembly axially moves up and down in support holes; Supporting plays a part sliding bearing; In the groove of its inner surface and outer surface cushion rubber is housed simultaneously, the supporting end face is equipped with oil-scraping ring, and cushion rubber and oil-scraping ring all are to prevent that the hydraulic oil in the cylinder from leaking outside.Cylinder-piston assembly is the piston of higher level's pillar and the cylinder of subordinate's pillar, is vital part, and its piston section chromium plating face size and surface quality are had relatively high expectations.This undercarriage was on active service twenties years, did not carry out large repairs, and cushion rubber, oil-scraping ring wear out, distortion, and the force of sliding friction between piston section and supporting is bigger.For overhauling the undercarriage damper leg, there is not specific purpose tool, use general utility tool; Can't decompose supporting from the buffering pillar safely; Be easy to shine into the scuffing of piston section chromium plating face, carve and hinder, part is exceeded to repair the limit, cause cylinder-piston assembly to scrap thus.Because cylinder-piston assembly is a special-purpose member, domestic no manufacturer all is external import, the cylinder-piston assembly expensive that therefore more renews, and the Buying Cycle is long, if damage, loses huge.
The utility model content:
The utility model technical problem to be solved is: overcome cylinder-piston assembly chromium plating face in the supporting decomposable process that exists in the background technology and be prone to produce darker scuffing, carve and hinder; And providing a kind of supporting to decompose instrument, this supporting decomposition instrument can decompose supporting and cylinder-piston assembly smoothly and it is not damaged.In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme:
A kind of undercarriage damper leg upper support decomposes instrument; Comprise cylinder-piston assembly; Be installed to the supporting on the cylinder-piston assembly, the supporting installed surface place on the cylinder-piston assembly is provided with the centering cutting ferrule of splitting, and it is characterized in that: decompose the cylindrical framework of instrument undersetting; Wherein in the undersetting ladder hole is arranged, the centering cutting ferrule is installed in the ladder hole.
This decomposition instrument further comprises: above-mentioned centering cutting ferrule middle part is broken off, and there is a circular open section junction.
This decomposition instrument also comprises upper bracket and undersetting, and the piston section on the above-mentioned cylinder-piston assembly places in the cutting ferrule circular open of feeling relieved in the undersetting, and upper bracket flexibly connects with the top.
This decomposition instrument also comprises: there is the screwed hole relative with the undersetting circular open at said upper bracket middle part, is installed with threaded rod in the screwed hole, and threaded rod one end is bull stick fixedly, and the other end passes the threaded openings of puller upper bracket, and the end of screw rod is installed the top.
The novel beneficial effect of this use is: this supporting decomposition instrument is owing to adopt said structure; The centering cutting ferrule is upwards embraced supporting from the supporting lower surface; The cutting ferrule of will feeling relieved places in the undersetting ladder hole; Make supporting decomposable process from the cylinder-piston assembly that a guiding control accurately arranged, make the direction of extracting supporting force consistent with the direction of cylinder-piston assembly axis; And it is the mode that adopts the feed screw nut that cylinder-piston assembly is moved in the support holes, in the decomposable process cylinder-piston assembly with bear the dead load effect but not shock loading.Avoid scratching and carve the chromium plating face of cylinder piston component of feeling frustrated.Protectiveness is strong, and workable and low cost and other advantages is discharged the possibility that cylinder-piston assembly damages through the practical operation check fully in decomposable process, has guaranteed the repair progress of undercarriage damper leg and has practiced thrift cost.

The specific embodiment:
Below in conjunction with accompanying drawing the utility model is described further:
With reference to accompanying drawing 1 and combine shown in the accompanying drawing 3, this supporting decomposition instrument comprises cylinder-piston assembly 10 and supporting 11, and said cylinder-piston assembly upper support installed surface 15 places are equipped with the centering cutting ferrule of splitting 5, and the cutting ferrule 5 of will feeling relieved again places in undersetting 6 stepped holes 9.Shown in accompanying drawing 2, decomposing the tool support seat is cylindrical frame, and upper bracket contacts with end face is movable, and centering cutting ferrule 2 middle parts are broken off and seen that Fig. 4, section junction have circular stepped openings 17.Cylinder-piston assembly chromium plating face 15 places in the centering cutting ferrule 5 circular stepped openings 17 with supporting lower surface 16; Upper bracket 3 flexibly connects with top 4, and there is the threaded openings 8 relative with the undersetting circular open at the upper bracket middle part, is installed with threaded rod 2 in the screwed hole; Threaded rod one end is bull stick 1 fixedly; The other end passes the threaded openings of puller upper bracket 3, and the end of screw rod is installed top 4, and the top is close to 14 with the piston base on the cylinder-piston assembly during decomposition.Upper and lower bearing is connected by 4 root posts, 7 usefulness screws.
When this decomposes tool work, earlier centering cutting ferrule 5 among Fig. 1 is taken off, erecting tools framework (top and threaded rod) makes down support level hole 9 be positioned at the below of supporting lower surface 16 to the piston section of Fig. 3.Two lobes centering cutting ferrule 2 is installed is embraced supporting, the adjustment frame position places in the undersetting stepped hole centering cutting ferrule, and the adjustment of rotation bull stick comes directly towards to piston section bottom.Bull stick on the rotary threaded bar arrives to the reaction force of supporting by the centering cutting ferrule, utilizes the slow rotating bolt of pitch of threaded rod that cylinder-piston assembly is extruded in support holes.
What need statement is, the protection domain of the utility model is as the criterion by the content of claims, and the content of the utility model specification is for better construe requires and the protection domain of unrestricted claim
