And the suitable frock of installation needs can just open piston ring and depart from and reinstall from annular groove in order to piston ring.Existing work
Dress is generally to be coordinated with piston ring using arcuate guide block, and the technical scheme exerted a force to frock using handle is with patent publication No.
As a example by the patent formula of CN102601768A, the piston ring disassembling fixture of the technical scheme has following shortcoming：
1st, one frock of this kind of technical scheme can only correspond to a kind of piston ring type of diameter, due to the patent application
" front end face of cover clamp is to coordinate piston-shaped circular arc ", therefore, the patent formula is only applicable to certain specific model, fits
It is small with scope；
2nd, the frock of the patent application pushes out gap-clearance of piston rings using on handle, so that piston ring is taken out, Ci Zhongshi
The bad control piston ring of power mode opens amplitude, and is easily damaged piston ring, so as to cause economic loss；
3rd, the frock of the patent is only piston ring disassembling fixture, is not suitable for the installation of piston ring；
4th, the frock of the patent is in dismounting, and the support effects to piston ring are bad, and piston ring easily drops to be caused to damage
Piston ring, so as to cause economic loss.
The content of the invention
The technical problem to be solved in the present invention is directed to the above-mentioned deficiency of prior art, there is provided a kind of simple structure, operation
It is easy, it is adaptable to engine piston ring assembly and disassembly frock and the method for different-diameter piston ring fast assembling-disassembling.
The technical scheme is that such：Including for supporting positioning piston ring and can adjust its width to be applied to
The telescoping support frame of different-diameter piston ring and positioned at the top of the support frame and coupled pluggable gap-clearance of piston rings
The interior stretching mechanism for opening piston ring, described stretching mechanism is provided with can drive the stretching mechanism uniform speed slow
Open so that the drive mechanism opened of gap-clearance of piston rings.
Used as further improving, described support frame is square set, and the square set includes that multiple relative can be slided
And the movable sleeve and connector being connected successively, one is provided between two movable sleeves therein and is connected with the stretching mechanism
Fixed block；Described stretching mechanism includes fixed plate and the slide plate that can be slided with respect to the fixed plate on the fixed block.
Further, gap cooperation is between the movable sleeve and connector and fixed block, also, in each work
Dynamic set and the joining place of connector and fixed block are equipped with the lock-screw that they can be locked and limited piston ring radial displacement.
Further, being respectively equipped with described fixed plate and slide plate can be while the positioning being plugged in gap-clearance of piston rings be dialled

Plate (32) is mobile, so that piston ring (1) opens, until when the internal diameter that piston ring (1) opens is more than the external diameter of piston crown, note
Under now slide plate (32) and fixed plate (31) relative position scale, piston ring (1) is then removed into piston, so that piston ring
(1) disassemble, finally, remaining piston ring (1) is opened and piston is removed according to the scale write down, realize rapid batch
Removing of piston ring (1).
