Abstract
The utility model discloses a connecting device of a hydraulic burster guide sleeve and a front cylinder body and belongs to the engineering machinery technical field. The structure of the connecting device comprises a guide sleeve, an axial fixed pin, a front cylinder body, a hexagon nut and an external tab washer, wherein the guide sleeve is arranged at one end of the front cylinder body; threaded holes are formed on the upper and lower faces of the front cylinder body; the axial fixed pin is screwed down and fixed in the threaded holes and externally fixed by the hexagon nut; besides, a counter bore is formed at the opening of the threaded hole and the hexagon nut is placed in the counter bore; and the guide sleeve bears no axial force in the working state on the burster, and thereby does not needs to be locked by a cylindrical pin. Compared with the existing product, the guide sleeve pin, the rubber plug and the hole retainer ring are omitted structurally, no circular-arc-shaped groove is milled on the guide groove, 2-phi 13 hole are symmetrically drilled on the same section, and the external tab washer is up to the GB/T856 standard; and the connecting device is simple in structure, low in processing cost, convenient for repair, high in hitting force, capable of improving the production efficiency, and the like.
Description
Technical field
The utility model relates to a kind of linkage that is applied to engineering machinery, relates in particular to a kind of hydraulic burster fairlead and front-bank rotor housing linkage.
Background technology
The New Hydraulic Impact Machine that hydraulic breaking hammer grew up the sixties in last century, take hydraulic pump as power source, oil liquid pressure is power, reciprocating motion of the pistons output impulse machine, utilize high-speed motion to impact bit shank, carry out crushing operation, obtained using comparatively widely with the boundary that digs up mine at engineering field.
Hydraulic burster is a kind of new and effective hydraulic shock vibration facility, auxiliary work parts of excavator or loader, realize the high-frequency reciprocating motion of destroyer piston in cylinder body with the hydraulic oil of machine-tool output during work, thereby hit drill steel, externally acting.
Hydraulic burster is widely used in the fields such as metallurgy, mine, railway, highway, building, urban construction, house exploitation, to the hard thing such as rock, concrete, ladle, slag, frozen soil, ice cube, cement pavement, bridge pier, building exploit, the operation such as fragmentation, dismounting.
Front-bank rotor housing is the vital part of destroyer, and destroyer has doing relatively reciprocating motion of continuous high speed with cylinder body at work, exists violent friction between moving period, and the lower surface is frequently clashed into drill steel again, and stress withstands shocks.Therefore, the quality that the destroyer front-bank rotor housing manufactures and designs directly has influence on reliability and the life-span of destroyer work, and reliable operation limit property and life-span are with to make the rear-bank rotor housing material closely related.
As accompanying drawing 1, in existing product or technique leading cover and front-bank rotor housing syndeton, be milled with two semi arch grooves on fairlead 1, be processed with pin-and-hole on front-bank rotor housing 3, arc groove equal diameters on pin-and-hole (fairlead pin 2) diameter and fairlead 1, pack into two fairlead pins of the rear use of front-bank rotor housing 32 of fairlead 1 insert pinning fairleads 3, prevent that fairlead 1 from dropping because of vibrations in destroyer work.Fairlead pin 3 firmly prevents from skidding off with back-up ring card 5 with the hole again, and then fairlead pin 2 apertures, hole clog with rubbery stopper 4 again.The advantage of this structure design is reliable, and fairlead 1 can not come off out.But this structure design part is many, arc groove processing time consuming on fairlead 1 cylindrical is bothersome, the fairlead pinhole on front-bank rotor housing 3 belongs to deep hole and especially adds difficulty with the place of passing through mutually that fairlead is joined the hole, hole in the hole significantly flies to have improved process time with the groove processing difficulties of back-up ring.
Summary of the invention
In order to solve deficiency of the prior art, the utility model provides a kind of hydraulic burster fairlead and front-bank rotor housing linkage, has that topology layout is reasonable, easy to maintenance, hitting dynamics increases, save processing cost, the advantage such as easy to use.
The utility model is to realize by following technical scheme:
Hydraulic burster fairlead and front-bank rotor housing linkage, its structure is made of: fairlead, axial restraint pin, front-bank rotor housing, hex nut, lock washer with tongue at outside, wherein fairlead is arranged at an end of front-bank rotor housing, the above and below of front-bank rotor housing is provided with screwed hole, axial restraint pin pin screws and is fixed in screwed hole, and the outside is fixed with hex nut.
Described screwed hole, its aperture go out also to be provided with counterbore, and hex nut is positioned in counterbore.
Described hex nut, the bonding surface of itself and front-bank rotor housing is provided with lock washer with tongue at outside, and the outermost end of hex nut and front-bank rotor housing be in same level, and equipment is when vibrations, and lock washer with tongue at outside can play the effect that prevents that hex nut is loosening.
Described fairlead, its working condition on crushing engine is not born axial force, therefore need not adopt straight pin locking.
The utility model is than existing product, cancel fairlead pin, rubbery stopper and hole back-up ring on structure, do not adopt on fairlead yet and mill arc groove, the hole that just symmetry is bored 2-φ 13 on same cross section, top and bottom at front-bank rotor housing, upper each bores has attacked screwed hole, there is counterbore in the aperture, by being screwed into the axial restraint pin in screw, and arrange in counterbore with hex nut, lock washer with tongue at outside adopts the GB/T856 standard, and simple in structure, cut down finished cost, save processing cost, easy to maintenance, hitting dynamics increases, the advantage such as enhance productivity.
