Abstract
The utility model provides a piston frock, relates to the piston assembling field of engine between the experimental period. Including the frock body that has the taper hole, the taper hole link up with the steel hole on the engine cylinder block, and the location tang of the bottom of frock body makes frock body and engine cylinder block link together. The device simple structure makes simply, adds through the machine and just can accomplish, and low cost, and the quality is light, and the installation is once only accomplished, the emergence was damaged when reducing the installation risk, and improvement work efficiency is a portable product, the most suitablely uses at laboratory test.
Description
Technical field
This utility model is related to the piston assembling field during engine test, particularly to a kind of piston frock.
Background technology
At present in the machinery industries such as automobile making, electromotor, Piston and rod assembly include piston, piston ring, piston pin,
Jump ring, connecting rod, bushing, connecting-rod bolts.During electromotor pre-stage test, frock used is all fairly simple, if can according to will
Ask and complete to install.When installing toward in cylinder body, piston ring installs piston in advance, under free state, due to ring itself
There is tension, during free state, be greater than cylinder diameter, if not being situated between with extraneous instrument during laboratory installation, by manual piston
It is extremely difficult it is easy to phenomenon of damaging that connecting rod loads in cylinder body.
Content of the invention
This utility model provides a kind of piston frock, solves the problems, such as that piston cannot smoothly be installed into engine cylinder-body,
Its structure is simple, reasonable in design, be easily installed.
This utility model be employed technical scheme comprise that：A kind of piston frock, is characterized in that, the frock with taper hole
Body, the bottom of frock body is provided with positioning spigot, and positioning spigot is plugged on the steel in the hole on engine cylinder-body, and steel hole with
Taper hole is formed through the connection chamber making piston external diameter gradually change, rounding between frock body and the connecting portion of positioning spigot
Angle.
As a kind of preferred version of the present utility model, in the relative two ends setting handle of the lateral wall of frock body.
As another kind preferred version of the present utility model, the lateral wall junction rounding of described handle and frock body
Angle.
As another preferred version of the present utility model, the taper hole external diameter positioned at frock body upper surface should be greater than piston
The maximum of external diameter, should be not less than the maximum of piston external diameter positioned at the taper hole external diameter of frock body lower surface.
The beneficial effects of the utility model are that this piston frock, including frock body, taper hole and electromotor with taper hole
Steel hole insertion on cylinder body, the positioning spigot of the bottom of frock body makes frock body and engine cylinder-body link together.Should
Apparatus structure is simple, is simple to manufacture, and by machine plus just can complete, and with low cost, light weight, installs and disposably completes, minimizing
The risk damaged during installation, improves work efficiency, is a kind of portable product, is best suitable for testing using in laboratory.
Brief description
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment
In required use accompanying drawing be briefly described it should be apparent that, drawings in the following description are only of the present utility model
Some embodiments, for those of ordinary skill in the art, on the premise of not paying creative work, also can be according to these
Accompanying drawing obtains other accompanying drawings.
Fig. 1 is the sectional view of piston frock in this utility model embodiment；
Fig. 2 is the top view of piston frock in this utility model embodiment；
In figure number explanation is as follows：1 frock shell, 2 handles, 3 taper holes, 4 roundings, 5 positioning spigots, 6 roundings.
Specific embodiment
So that above-mentioned purpose of the present utility model, feature and advantage is become apparent from understandable, below in conjunction with the accompanying drawings 1, Fig. 2 and
Specific embodiment is described in further detail to this utility model.
Embodiment 1：
The piston frock adopting in the present embodiment, its concrete structure is as shown in Figure 1.Frock shell 1 in the present embodiment is made
For frock body, frock shell 1 is provided with taper hole 3, taper hole 3 is suitable for reading big, the little structure of lower mouth.In order to avoid because frock many
Cause confusion phenomenon, can beat blaze at the place suitable for reading of taper hole 3 and know.
The bottom of frock shell 1 is provided with positioning spigot 5, under the frock shell 1 that the reversed cone angle 3 in the present embodiment is located
The roughness of plane is higher than the roughness of engine cylinder-body itself, and positioning spigot 5 width is the smaller the better, positioning spigot 5 grafting
Steel in the hole on engine cylinder-body, and steel hole is formed through, with taper hole 3, the connection chamber making piston external diameter gradually change, piston leads to
After crossing above-mentioned connection chamber, due to positioning spigot 5 outside diameter identical with engine cylinder-body diameter so that this piston frock and starting
Machine cylinder body completes reasonable coordination.
Rounding 6 between the connecting portion of frock shell 1 and positioning spigot 5, is more beneficial for piston and passes through piston frock.
In the present embodiment, the installation process of piston frock is as follows：Piston rod is vertically put in cylinder first, is pushed away by manual
Piston moves downward along the taper hole of piston frock, and piston ring is subject to the taper hole of big upper and lower small mouth to gradually taper up after extruding, and arrives
Reach lowest part to match with cylinder holes completely, and then realize installing.
Embodiment 2：
The present embodiment is with the difference of embodiment 1：In the present embodiment, the concrete structure of taper hole is：Positioned at frock shell 1
Taper hole 3 external diameter of upper surface should be greater than the maximum of piston external diameter, and taper hole 3 external diameter positioned at frock shell 1 lower surface should not be little
Maximum in piston external diameter.As shown in Figure 2.
Roughing is carried out on steel pipe, then carries out heat treatment, carry out polish, phase on the periphery of frock shell 1
To both sides welding handle 2, and the connecting portion rounding 4 in frock shell 1 and handle 2, become light after connecting portion polishing
Sliding surface.Make piston frock convenient when using after adding handle 2.
Although the foregoing describing specific embodiment of the present utility model, those skilled in the art in the art should
Work as understanding, these are merely illustrative of, various changes or modifications can be made to these embodiments, new without departing from this practicality
The principle of type and essence.Scope of the present utility model is only limited by the claims that follow.
