Abstract
The utility model discloses an appurtenance of assembly piston, this appurtenance of assembly piston includes: two semicircle clamp ring, these two semicircle clamp ring's front end is together articulated through an articulated shaft, and two handles, each is connected two semicircle clamp ring's rear end with the front end of this handle. The cover is equipped with a torsion spring on the articulated shaft, torsion spring's upper end inlay card is at one of them on the semicircle clamp ring, just torsion spring's lower extreme inlay card is at another on the semicircle clamp ring. The utility model discloses can ensure piston ring breaking occur not in assembling process to the trouble that can effectively prevent the piston ring scuffing of cylinder bore takes place.
Description
Technical field
The utility model relates to piston field, particularly a kind of aid assembling piston.
Background technology
At present, in the process of cylinder sleeve piston being installed to engine, being that recruitment is sleeved is pushed into piston in cylinder sleeve, because piston needed first to install piston ring before being installed in cylinder sleeve, piston ring diameter is in its natural state the diameter being greater than cylinder sleeve, when promoting piston by frock sleeve, need while promote piston to enter cylinder sleeve, cylinder sleeve diameter is less than while piston ring is compressed to, its installation effectiveness is low, the fracture and piston ring is easily squeezed, thus the fault that ring scuffing easily occurs.
The information being disclosed in this background technology part is only intended to increase the understanding to general background of the present utility model, and should not be regarded as admitting or imply in any form that this information structure has been prior art that persons skilled in the art are known.
Utility model content
The purpose of this utility model is to provide a kind of aid assembling piston, thus overcomes and existingly install the low and shortcoming of the easy extrusion fracture of piston ring of the efficiency of piston by frock sleeve.
For achieving the above object, the utility model provides a kind of aid assembling piston, wherein, comprising: two semicircle clamp rings, and the front end of these two semicircle clamp rings is hinged by a jointed shaft; And two handles, the rear end of described two semicircle clamp rings is respectively connected with the front end of this handle.
Preferably, in technique scheme, described jointed shaft is arranged with a torsionspring, the upper end inlay card of described torsionspring is wherein on a described semicircle clamp ring, and on lower end inlay card semicircle clamp ring described in another of described torsionspring.
Preferably, in technique scheme, the rear end of described two handles is provided with anti-skid design.
Preferably, in technique scheme, between each described semicircle clamp ring and connected described handle, be provided with reinforcement.
Compared with prior art, the utility model has following beneficial effect:
The utility model is by two semicircle clamp ring clamping pistons; and make piston ring be compressed to the size corresponding with piston; to be less than the diameter of cylinder sleeve; and then after piston is aligned cylinder sleeve; piston is pushed in cylinder sleeve and completes installation; it can guarantee that piston ring does not rupture in assembling process, thus can effectively prevent the fault of ring scuffing from occurring.
Accompanying drawing explanation
Fig. 1 is the top view of the aid according to the utility model assembling piston.
Fig. 2 is the front view of the aid according to the utility model assembling piston.
Main Reference Numerals illustrates:
1-semicircle clamp ring, 2-jointed shaft, 3-handle, 4-anti-skid design, 5-reinforcement, 6-torsionspring.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail, but is to be understood that protection domain of the present utility model not by the restriction of detailed description of the invention.
Clearly represent unless otherwise other, otherwise in whole description and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or part, and do not get rid of other element or other part.
Fig. 1 to Fig. 2 shows a kind of structural representation assembling the aid of piston according to the utility model preferred embodiment, the aid of this assembling piston comprises semicircle clamp ring 1 and handle 3, with reference to figure 1, the diameter of semicircle clamp ring 1 is corresponding with the diameter of piston, and the width of semicircle clamp ring 1 and the width of piston corresponding, the medial surface of semicircle clamp ring 1 can be equipped with padded coaming, to prevent damage piston and piston ring when clamp piston.The front end of two semicircle clamp rings 1 is hinged by a jointed shaft 2, with can opening and closing.The rear end of two semicircle clamp rings 1 is respectively connected with the front end of a handle 3, thus controls the opening and closing of two semicircle clamp rings 1 by two handles 3.Preferably, the rear end of two handles 3 is provided with anti-skid design 4, so that workman's control crank 3.Further preferably, reinforcement 5 is provided with between each semicircle clamp ring 1 and connected handle 3, to improve intensity.
Preferably, with reference to figure 2, the front end of two semicircle clamp rings 1 is convexly equipped with hinged ear, jointed shaft 2 is sheathed on the hinged distant of two semicircle clamp rings 1, and jointed shaft 2 is arranged with a torsionspring 6, on the hinged ear of the upper end inlay card of a torsionspring 6 semicircle clamp ring 1 wherein, and the lower end inlay card of torsionspring 6 is on the hinged ear of another semicircle clamp ring 1.Jointed shaft 2 is arranged with torsionspring 6, thus two semicircle clamp rings 1 can be made to be in open configuration in its natural state, easy to use.
When piston is installed; by two semicircle clamp ring 1 clamping pistons; thus compression ring; piston ring is made to be less than the diameter of cylinder sleeve; then by two semicircle clamp rings 1 being withstood on the end face of body; and piston and cylinder sleeve are aligned; while maintenance clamp piston, piston is pushed in cylinder sleeve again; this process piston ring is in the state being compressed to and being less than cylinder sleeve always; thus piston ring can be made to enter into cylinder sleeve smoothly; to guarantee that piston ring does not rupture in assembling process, thus can effectively prevent the fault of ring scuffing from occurring.
The aforementioned description to concrete exemplary of the present utility model is to illustrate and the object of illustration.These descriptions not want the utility model to be defined as disclosed precise forms, and obviously, according to above-mentioned instruction, can much change and change.The object selected exemplary embodiment and describe is to explain certain principles of the present utility model and practical application thereof, thus those skilled in the art can be realized and utilize various different exemplary of the present utility model and various different selection and change.Scope of the present utility model is intended to limited by claims and equivalents thereof.
