It is disposed with baffle, the baffle includes the bottom parts being connected with the clamping end, vertical plate part and is located at the vertical plate part
The clamp portion of upper end, the piston ring mutually limit cooperation, and the pressing plate portion with the vertical plate part and the clamp portion
Point with the wedge shaped arrangement in vertical plate part, and there is therebetween wedge groove, the osculum part of the wedge groove is located at described
The inside of clamping end, the big oral area quartile of the wedge groove is in the outside of the clamping end, though it will can easily live in this way
Plug ring is installed in piston ring groove, but is not easy to take out piston ring out of piston ring groove, and concrete reason is as described below:
1, the thickness of clamping end and baffle is greater than the width of piston ring groove, and clamping end and baffle can not thus protrude into
Piston ring groove is interior and engages the two-port of piston ring;
2, it is left pincers and the clamping end on right pincers overall width be greater than piston ring opening width, can equally make clamping end and
Baffle can not engage the two-port of piston ring.
Utility model content
For the above-mentioned prior art, simple, operation that the technical problem to be solved by the present invention is to provide a kind of structures
Easy piston ring installing and dismounting device.
In order to solve the above technical problems, the utility model provides a kind of piston ring installing and dismounting device, including caliper and
Clamping part, the left pincers of the caliper and the clamping end of right pincers are symmetrically equipped with the clamping part, and the clamping part is set as and piston
The arc that ring matches, the clamping part include clamping part ontology, the engaging slot that clamping part body central is arranged in and setting
The wedge-shaped protrusion of one end in engaging slot.
More preferably, the distance on the opposite two wedge-shaped protrusion tops is B=5~10mm, the top of the wedge-shaped protrusion
Face is C=2~4mm at a distance from the top surface of the clamping part ontology, and the width of the wedge-shaped protrusion is D=1~2mm.
More preferably, the radian of the clamping part ontology is A=30 °~45 °.
More preferably, the width of the engaging slot is E=3~8mm.
More preferably, which further includes the guiding module for being mounted on top land.
Compared with the prior art, the beneficial effects of the utility model are: passing through the folder in the clamping end of caliper setting arc
Portion is held, the both ends of piston ring can be made to be maintained in engaging slot well in this way, without because making to live when outside swell piston ring
Plug ring pops up outward, scratches piston or accidental injury operator to damage piston ring or damage;In addition, through reasonable settings
Wedge-shaped protrusion, can be such that wedge-shaped protrusion protrudes into piston ring groove in this way, and the both ends of the surface of piston ring is then made to be resisted against wedge-shaped protrusion
On lozenges, and it is resisted against the outer diameter face at piston ring both ends on the bottom surface of engaging slot, thus can be easily by piston
Ring takes out out of piston ring groove.
