Description
Technical field
The present invention relates to a kind of plunger assembly, specifically the seaming tool of plunger assembly, belong to plunger assembly technical field.
Background technology
Plunger displacement pump due to compact conformation, pressure compact, efficiency is high and be easy to adjustly widely used in the industry such as engineering machinery, agricultural machinery.Plunger assembly is core part wherein, and plunger assembly closing in quality directly affects performance and the life-span of pump (motor).Seaming tool directly determines closing in quality.This just has higher requirement to the Design and manufacture of seaming tool.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, thus a kind of plunger assembly seaming tool is provided, closing in quality and the stability of plunger assembly can be improved, thus improve plunger pump performance and service life.
According to technical scheme provided by the invention, plunger assembly seaming tool comprises external conical sleeve, Closing in die, supporting seat, base, backstay and spring, it is characterized in that: external conical sleeve is fixed on base, is provided with positioning chamber in base; Be provided with centre bore in external conical sleeve, in centre bore, be provided with Closing in die and supporting seat successively from top to bottom; External conical sleeve internal upper part is provided with inner conical surface, and Closing in die outer surface is provided with the male cone (strobilus masculinus) coincide with the inner conical surface of external conical sleeve, and external conical sleeve realizes being connected by inner conical surface and male cone (strobilus masculinus) with Closing in die; In described Closing in die center be provided with successively be from top to bottom interconnected closing in chamber, adapter cavity and upper plug chamber; Supporting seat central upper portion is provided with lower plunger chamber, and the lower center of supporting seat is provided with backstay, and backstay stretches into positioning chamber, pocketed springs on backstay, spring upper end contact supporting seat lower surface, lower spring end contact positioning chamber lower surface.
Further, external conical sleeve comprises two Closing in die piecemeals, and two Closing in die piecemeals are arranged symmetrically with.
Further, the diameter of adapter cavity is less than the diameter in closing in chamber and upper plug chamber.
Compared with the prior art the present invention has the following advantages:

Detailed description of the invention
Embodiment in is by reference to the accompanying drawings further described by the present invention below:
As shown in Figure 1, the present invention mainly comprises external conical sleeve 1, Closing in die 2, supporting seat 3, base 4, backstay 5 and spring 6, and external conical sleeve 1 is fixed on base 4, is provided with positioning chamber 11 in base 4.Be provided with centre bore in external conical sleeve 1, in centre bore, be provided with Closing in die 2 and supporting seat 3. from top to bottom successively
External conical sleeve 1 internal upper part is provided with inner conical surface, and Closing in die 2 outer surface is provided with the male cone (strobilus masculinus) coincide with the inner conical surface of external conical sleeve 1, and external conical sleeve 1 realizes being connected by inner conical surface and male cone (strobilus masculinus) with Closing in die 2.In described Closing in die 2 center be provided with successively be from top to bottom interconnected closing in chamber 7, adapter cavity 8 and upper plug chamber 9, the diameter of adapter cavity 8 is less than the diameter in closing in chamber 7 and upper plug chamber 9.
Described external conical sleeve 1 comprises two Closing in die piecemeals, and two Closing in die piecemeals are arranged symmetrically with.
Supporting seat 3 central upper portion is provided with lower plunger chamber 10, and the lower center of supporting seat 3 is provided with backstay 5, and backstay 5 stretches in positioning chamber 11, pocketed springs 6 on backstay 5, spring 6 upper-end contact supporting seat 3 lower surface, spring 6 times end in contact positioning chamber 11 lower surfaces.
In use, plunger B upper and lower side is placed in upper plug chamber 9 and lower plunger chamber 10 respectively, and piston shoes A is placed in closing in chamber 7 in the present invention.Downward promotion Closing in die, makes the conical surface of Closing in die and tapered sleeve bonded to each other, and meanwhile, two Closing in die piecemeals are also bonded to each other.The lower end of piston shoes is provided with the bulb closing in chamber of installing plunger, and the bulb of plunger loads the extruding generation plastic deformation also by Closing in die in closing in chamber, thus reaches the object of closing in.Spring withstands plunger by supporting seat and makes plunger in whole closing in process, paste jail all the time with piston shoes thus ensure that the stability of closing in post gap.Piston shoes A omoplate face with close up between Closing in die plane before size L1(piston shoes produce plastic deformation before) to ensure to close up after piston shoes omoplate face do not contact with between Closing in die plane, prevent from producing between the two and interfere thus the effect that closes up of impact.Size L2 need be greater than size L1. to be prevented from producing between support bar and base interfering.
Structure of the present invention is simple, compact, reasonable, can improve closing in quality and the stability of plunger assembly, thus improves plunger pump performance and service life.
