Description
Technical field
The utility model relates to a kind of frock, particularly relates to a kind of piston cooling nozzle assembly tooling.
Background technology
Independently parts during the piston cooling nozzle of usual application, piston cooling nozzle is fixed on motor body, and be communicated with cooling fluid inlet ports, the position of nozzle is determined precisely to produce one region pointing to the piston back side to cool piston, piston cooling nozzle generally includes a valve, in order to block the flowing of cooling fluid, until the pressure in cooling circuit exceedes specific threshold value, piston cooling nozzle is fixed on motor body by screw, in prior art, on motor body, the installing space of corresponding piston cooling nozzle is narrow and small, existing instrument is used to be difficult to assembly work, assembly difficulty is large, efficiency is low.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of piston cooling nozzle assembly tooling, piston cooling nozzle carried out prepackage and tighten in advance, solve piston cooling nozzle assembly space narrow and small, the problem of assembling difficulty, makes operator's simple operation, shortens the assembly manipulation time, improve efficiency of assembling, reduce product cost.
Piston cooling nozzle assembly tooling of the present utility model, comprises body and rod member; Described rod member inserts body endoporus and rotates and axial sliding fit, body lower end inner hole wall and cooling jet contour structures match for putting into cooling jet and at least circumferentially positioning cooling jet, and described rod member lower end is the outer-hexagonal header structure matched with the hexagon socket head cap screw on cooling jet.
Further, described body lower end sidewall is provided with the bulb plunger for radially holding out against cooling jet; Be threaded connection between described bulb plunger and body.
Further, described body lower end corresponding nozzle oil pipe is provided with slot to make way.
Further, described rod member comprises the dwang inserted in body, and the upper end of described dwang is stretched out by body, and described rod member also comprises the handle head being fixed on dwang upper end.
Further, be connected and fixed by straight pin between described handle head and dwang.
The beneficial effects of the utility model are: piston cooling nozzle assembly tooling of the present utility model, piston cooling nozzle can be carried out prepackage and tighten in advance, solve piston cooling nozzle assembly space narrow and small, the problem of assembling difficulty, make operator's simple operation, shorten the assembly manipulation time, improve efficiency of assembling, reduce product cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Fig. 1 is structural representation of the present utility model, as shown in the figure: the piston cooling nozzle assembly tooling of the present embodiment, comprises body 1 and rod member 2; Described rod member 2 inserts body 1 endoporus and rotates and axial sliding fit, body 1 lower end inner hole wall and cooling jet 7 contour structures match for putting into cooling jet 7 and at least circumferentially positioning cooling jet 7, and described rod member 2 lower end is the outer-hexagonal header structure matched with the hexagon socket head cap screw on cooling jet 7; Cooling jet 7 can be carried out prepackage and tighten in advance, solve cooling jet 7 assembly space narrow and small, the problem of assembling difficulty, makes operator's simple operation, shortens the assembly manipulation time, improves efficiency of assembling, reduces product cost;
Use flow process: piston cooling nozzle puts into body 1 lower end, its external diameter and pressing sleeve inner hole, withstands nozzle prevent from coming off by the steel ball of bulb plunger, makes nozzle oil pipe in slot to make way; Handle drives the outer-hexagonal head of dwang head to screw in the inner hexagonal hole of nozzle bolts; The frock installing nozzle is accurately put into the installing hole of cylinder body and located; Drive nozzle hexagon socket head cap screw to rotate by turning handle head, make it screw in and install in screwed hole, and reach the fastening object of prepackage.Use this frock to efficiently solve piston cooling nozzle installation site narrow space, be unfavorable for that operative employee assembles, thus affect the problem of productive temp, product assembly quality.
In the present embodiment, described body 1 lower end sidewall is provided with the bulb plunger 3 for radially holding out against cooling jet 7; Be threaded connection between described bulb plunger 3 and body 1, improve the position stability of cooling jet 7, prevent cooling jet 7 from coming off.
In the present embodiment, described body 1 lower end corresponding nozzle oil pipe 8 is provided with slot to make way, can be ensured circumferentially to the performance that cooling jet 7 is located with coordinating of nozzle oil pipe 8 by slot to make way.
In the present embodiment, described rod member 2 comprises the dwang 4 inserted in body 1, and the upper end of described dwang 4 is stretched out by body 1, and described rod member 2 also comprises the handle head 5 being fixed on dwang 4 upper end, and turning handle head 5 can drive dwang 4 to rotate, convenient operation.
In the present embodiment, be connected and fixed by straight pin 6 between described handle head 5 and dwang 4, syndeton is simply compact, is convenient to assembling, can improves the stress performance between handle head 5 and dwang 4.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
