Background technology
Elastic spring is the strength member limiting piston movement position, and the length of its assembly work directly decides the assembly work duration of piston assembly.Due to elastic spring light weight, volume is little and hardness is high, causes its assembly work long.The bad assurance of force value during the assembling of whole piston assembly, needed for existing elastic spring assembly tooling, it is impossible to ensure the smooth and easy of elastic spring assembling.
Currently used elastic spring assembly tooling, as illustrated in figures ia and ib, assemble flow is its topology view: be first placed in piston 2 pommel on assembling table top 1；Secondly in guide post 3 jag loads piston 2 at cylinder, it is ensured that guide post 3 anchor ring well fits together with piston 2 upper end anchor ring；Furthermore elastic spring 5 is loaded guide post 3 outer conical surface；Then tweezers 4 two ends are utilized to act on elastic spring 5 upper end；Finally utilizing operator's both hands act on tweezers 4 and down exert a force, result elastic spring 5 can against guide post 3 outer conical surface and constantly becomes large diameter and move down until loading in piston 2 cylindrical groove.
This frock has certain limitation:
1, this frock can only determine the piston 2 direction on assembling table top 1 by hands, it is difficult to ensure that piston 2 axis is perpendicular to assemble table top 1, when tweezers 4 stress acts on piston 2, piston 2 perhaps can slide on assembling table top 1, causes an elastic spring assembling unsuccessful；
2, this frock can only act on tweezers 4 by operator's both hands and down exert a force, and owing to the active area of tweezers 4 is little and stress big, operator's both hands can feel under the weather, and long-time operation can cause hand to ache thus more extend assembly work；
3, this frock acts on tweezers 4 by operator's both hands and down exerts a force, if the power that operator applies is excessive, due to inertia, tweezers 4 can be crossed piston 2 cylindrical groove and contact with piston 2 external cylindrical surface, thus piston 2 external cylindrical surface caused cut so that scrapping whole piston 2.
Summary of the invention
The technical problems to be solved in the utility model is: by hands, existing frock can only determine that piston is placed on the direction on assembling table top, can only act on tweezers by operator's both hands and down exert a force.
In order to solve above-mentioned technical problem, the technical solution of the utility model there is provided a kind of elastic spring assembly tooling, the pommel of piston is bottom, it is top that piston has the end of the cylindrical groove for loading elastic spring, it is characterized in that: include locating piece, piston bottom end stretches in locating piece vertically, and the top of piston is exposed to outside locating piece, it is provided with the guide post with piston coaxial on the top of piston, it is arranged over having the pressing plate of through hole at guide post, the shape of through hole matches with guide post, pressing plate is provided with the force sleeve of band blind hole, blind hole in force sleeve communicates with the through hole on pressing plate, pressing down on force sleeve makes guide post penetrate the through hole of pressing plate and the blind hole in sleeve that exerts a force, simultaneously, set elastic spring on the guide bar is pressed downward in the cylindrical groove of piston by pressing plate along guide post.
Preferably, the diameter of described guide post is gradually increased to bottom by upper end.
Preferably, in described locating piece, it is provided with the separation sleeve being enclosed within outside described piston, is provided with the limited block fixed with described locating piece in the lower section of separation sleeve.
Preferably, described limited block is by cylindrical and described locating piece inner circle interference fit.
Preferably, described separation sleeve is by cylindrical and described locating piece inner circle matched in clearance.
Preferably, described guide post is truncated cone-shaped.
Preferably, described pressing plate is combined by 4 pieces of sub-pressing plates.
Preferably, the outer circumference surface of described pressing plate is provided with ring spring.
Preferably, the outer circumference surface of described pressing plate has the ring-shaped groove for installing described ring spring.
The utility model has the advantages that: provide that a kind of operation possibility is high, practical, high efficiency elastic spring assembly tooling.

Detailed description of the invention
For making this utility model become apparent, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
In conjunction with Fig. 2 to Fig. 4, a kind of elastic spring assembly tooling that this utility model provides specifically includes: locating piece 6, limited block 7, separation sleeve 8, piston 2, elastic spring 5, guide post 9, ring spring 10, pressing plate 11, force sleeve 12.
Locating piece 6 is limited block 7 and the main body of separation sleeve 8 assembling.It is used for positioning piston 2 by locating piece 6, prevents piston 2 all directions from sliding.Locating piece 6 is designed with endoporus, can match with limited block 7 cylindrical and install facility very well, use steel material simultaneously, have certain weight, be difficult to and workbench generation sliding friction, it is ensured that stablizing of location piston 2.Limited block 7 is installed convenient and changes conveniently, uses plastic material simultaneously, and quality is softer, is effectively protected piston 2 sphere and makes its surface roughness unaffected.Limited block 7 is by cylindrical and locating piece 6 inner circle interference fit, to guarantee limited block 7 difficult drop-off.Separation sleeve 8 is by cylindrical and locating piece 6 inner circle matched in clearance, to guarantee that separation sleeve 8 is easily changed.Separation sleeve 8 is designed with endoporus, and the cylindrical of separation sleeve 8 can match with locating piece 6 inner circle very well, installs convenient and changes conveniently, using plastic material simultaneously, and quality is softer, is effectively protected piston 2 cylindrical and makes its surface roughness unaffected.
Be provided with guide post 9 on the top of piston 2, guide post 9 uses circular platform type structure and uses steel alloy material and heat treatment requirements, it is simple to the installation of elastic spring 5 and slip, and improves the service life of guide post 9.
Being realized the reset of 4 block pressur plates by ring spring, realize elastic spring by guide post and assemble the direction of motion normally, the transmission being realized power by force sleeve acts on pressing plate.Acting on pressing plate by force sleeve transmission power, pressing plate stress promotes elastic spring to move along guide post to piston outer channel until entering piston outer channel to complete the assembling of elastic spring.
Pressing plate 11 is reasonably combined by 4 pieces of sub-pressing plates, and uniform stressed acts on elastic spring 5.Being provided with ring-shaped groove on pressing plate 11, ring spring 10 is fixed in ring-shaped groove.Ring spring 10 is for the reset of pressing plate 11.The ring-shaped groove of design, is on the one hand conducive to ring spring 10 to install stable, on the other hand can guarantee that ring spring 10 will not take off ditch in the case of stretching and compression, uses non-metallic material, protection elastic spring 5 not to be affected by responsive to axial force simultaneously.
Force sleeve 12 is provided with the blind hole of certain internal diameter and the degree of depth, it is to avoid during assembling elastic spring 5, force sleeve 12 is interfered with guide post 9 and caused the pressing plate 11 cannot stress.
Before using, locating piece 6, limited block 7 and separation sleeve 8 are installed together.
During use, locating piece 6 is placed on fitter's bench, notes limited block 7 down simultaneously.Place into piston 2, note pommel down simultaneously.Piston 2 upper end loads guide post 9.Elastic spring 5 to be installed is loaded on guide post 9 taper seat.Elastic spring 5 upper end and guide post 9 taper seat load the pressing plate 11 with ring spring 10.Pressing plate 11 upper ends force sleeve 12.Force sleeve 12 is applied downward power, and elastic spring 5 can move down until entering the cylindrical groove of piston 2 along guide post 9, completes the assembling of elastic spring 5.
Above-mentioned frock is such as placed on hand press operation, in hgher efficiency.
