The specific embodiment
As shown in Figure 1 to 11, this piston ring attaching/detaching apparatus consists of with adjusting part support, handle 6, jacking block 5, opening piece 4.Support is by rack body 1, rack platform 2 and a plurality of support convex shoulders 3, and rack body 1 is circular ring.A plurality of support convex shoulders 3 are for being fastened on the gap between piston and rings, the similar trapezium structure of its shape, and be evenly distributed on the inwall of rack body.In addition, the shape of support convex shoulder also can adopt semicircular structure.The bottom wall of support convex shoulder is fixed on the internal face of rack body, and its top wall is fastened in the gap between piston and rings, and support convex shoulder consists of top-support convex shoulder and bottom bracket convex shoulder.In the present embodiment, the quantity of support convex shoulder is three, and its principle is three-point fix principle.
The top of handle 6 is arranged in handle mounting groove 11, is provided with the cavity 23 running through for adjusting part in handle 6, on the internal face of cavity 23, is provided with boss, thereby forms gathering sill 12.The size of the top end face opening of this cavity is greater than the size of its bottom end face opening.The top end face of handle and the top end face of cavity are same end face, and the bottom end face of handle and the bottom end face of cavity are same end face.
The mode that adjusting part adopts key to connect is arranged in handle mounting groove 11, and its front end is connected with the end of jacking block 5.In the present embodiment, adjusting part by adjusting bolt 8 and be set in its outside follower lever 7 form, the internal thread of follower lever is connected with the external screw thread of adjusting nut, and the outside wall surface of follower lever 7 is provided with the feather key 24 matching with gathering sill 12 in handle mounting groove 11.Because feather key matches with gathering sill, so follower lever can only moving linearly and can not be circled.
Jacking block 5 is arranged on jacking block slide rail 10, and is arranged on the lower end of opening piece 4, and jacking block is carrying out rectilinear motion under the promotion of follower lever in jacking block slide rail.Jacking block 5 consists of with bottom jacking block 15 the top jacking block 14 being connected, and is connected and fixed by bolt.Wherein, the front end of top jacking block 14 is provided with for forcing opening piece 4 to the point 13 of both sides motion, and end is planar structure.Top jacking block 14 lateral cross section be shaped as T shape structure, the longitudinal part in this T shape structure is arranged in jacking block slide rail, the bottom end face of the bottom end face of this longitudinal part and jacking block slide rail is horizontal structure.
Opening piece 4 is arranged on opening piece slide rail 9, and its front end is provided with for inserting the insertion end 16 of piston ring hasp gap location, and its end is provided with the cone tank 17 inserting for point 13.Opening piece 4 is identical by phase structure and position is corresponding left opening piece 18 and right opening piece 19 form, and wherein, the left opening piece of take is example, and left opening piece 18 consists of with lower-left opening piece 21 the upper left opening piece 20 being connected, and is connected and fixed by bolt.The front end of upper left opening piece 20 is provided with for inserting the left part of piston ring hasp gap location, comprises left-leaning inclined-plane in inner wall surface thereof, and the shape of lower-left opening piece is identical with the shape of opening piece slide rail, is dovetail structure.Right opening piece consists of the upper right opening piece being connected and bottom right opening piece, and is connected and fixed by bolt.The front end of upper right opening piece is provided with for inserting the right part of piston ring hasp gap location, comprises Right deviation inclined-plane in inner wall surface thereof, and the shape of bottom right opening piece is identical with the shape of opening piece slide rail.Left part contacts to form insertion end 16 with right part, the cone tank 17 that the left-leaning inclined-plane in left-leaning inclined-plane inserts to be configured for point near the Right deviation inclined-plane in Right deviation inclined-plane.
Jacking block moves to the position of opening piece under the effect of follower lever, thereby point is inserted in cone tank, and left and right opening piece forces left and right opening piece to its two side shifting under the squeezing action of point.
Job step of the present utility model is, rack body is put into and needs the piston ring position place that takes out, and one of dismounting personnel hold handle, allow support convex shoulder enter into the gap of piston ring and piston ring groove; The insertion end of getting out of the way buccal mass front end enters into the hasp gap location of piston ring, now, operating personnel are rotated counterclockwise adjusting bolt with an other hand, swivel bolt forces follower lever outward movment by the connection of screw thread, follower lever promotes jacking block and moves forward, jacking block inserts in the cone tank of opening piece end by the point of its front end, forces left and right opening piece to its two side shifting, thereby make left and right opening piece be separated position under the squeezing action of point.Because the front end of opening piece acts on the hasp place of piston ring, force piston ring to overcome the elastic force of self and open, when the outer of piston ring encounter rack body interior along time stop the rotation of adjusting bolt, now, the diameter of piston is 300mm, and the minimum diameter of support convex shoulder is 305mm, so just be easy to a piston ring together with support from piston that out, then adjusting bolt turns clockwise, and piston ring, by the elastic returning original state of self, is taken out from support.The dismantlement work of piston ring completes.
Only as described above, be only preferred embodiment of the present utility model, such as professional who are familiar with this art. after understanding technological means of the present utility model, natural energy, according to actual needs, is changed under instruction of the present utility model.Therefore all equal variation and modifications of doing according to the utility model claim, once should still belong in the scope that the utility model patent contains.
