The specific embodiment
The utility model is described further through embodiment below in conjunction with accompanying drawing.
Embodiment 1: referring to each accompanying drawing.
A kind of valve oil seal extracting tool; Porose and be socketed with the screw shaft 1 that handle 6, hypomere have external screw thread 1-1 by the upper end; The upper end be fixedly connected (weld or bonding etc.) with screw shaft 1 lower end or be connected as a single entity, elastic metallic opening sleeve 4 that the lower end inward flange has the arc cam 4-2 that is oppositely arranged; Be actively set on the outer support cylindrical shell 3 of opening sleeve 4 and one section screw shaft 1, be positioned at and support that knob nut 2 that cylindrical shell 3 tops are threaded with the external screw thread 1-1 of screw shaft 1 is formed and the nylon (or other is nonmetal) that is socketed in an end section outer surface that supports cylindrical shell 3 is protected positioning sleeve 5; Said opening sleeve 4 lower end outward flanges have cylindrical arc convex 4-1; The epimere of said opening sleeve 4 has valve oil seal conveying end 4-3.
The method for using of this embodiment is:
Step 1: turning knob nut 2; Be displaced downwardly to cylindrical arc convex 4-1 up to opening sleeve 4 and break away from support cylindrical shell 3; The valve oil seal extracting tool is aimed at cylinder cap tappet hole; With hand lower handle 6 bars, guarantee that the seam card (or claiming jaw) of the arc cam 4-2 that the is oppositely arranged formation of opening sleeve 4 blocks valve oil seal 7;
Step 2: will support cylindrical shell 3 and put into cylinder cap tappet hole, one holds handle 6 (it guarantees that opening sleeve 4 does not rotate), and a hand turning knob nut 2 is up to valve oil seal 7 is left behind from the head valve sleeve pipe;
Step 3: take off the valve oil seal extracting tool, repeating step 1 is got second valve oil seal.
Step 4: after the valve oil seal dismounting, turning knob nut 2 makes it separate with screw shaft 1, and valve oil seal 7 is taken out in the valve oil seal conveying end 4-3 of opening sleeve 4.
This embodiment utilization secondary principle that is threaded, rotating nut make the screw axial motion, drive open sleeve valve oil seal is dismantled from valve guide bushing; The nylon jacket of extracting tool cooperates the location with cylinder cap tappet hole, positioning stablity, reliable, accurate; The force part of instrument and cylinder body is a plane contact, and is stressed indeformable greatly; Produce axial tensile force by the screw thread transmission, operate easily laborsaving; Can deposit many oil sealings in the open sleeve, convenient many valve oil seal dismountings.
The utility model is not limited to the foregoing description, and the utility model content is said all can implement and have said good result.
