Specific embodiment
Below against attached drawing, by the description of the embodiment, making to specific embodiment of the present utility model further detailed
Thin explanation, it is therefore an objective to help those skilled in the art to the design of the utility model, technical solution have it is more complete, accurate and
Deep understanding, and facilitate its implementation.
As shown in Figure 1 to Figure 3, a kind of valve oil seal disassembling fixture, including handle 1 and sleeve 2, sleeve 2 is interior to be equipped with guiding
Channel, which further includes connecting rod 3, clamping jaw 4 and being moved by connecting rod 3 along guide channel makes clamping jaw 4 stretch out opening, retraction tightening
Regulating mechanism, handle 1 connect with connecting rod 3.Preferably, one end that connecting rod 3 connects handle 1 is threaded ends, and handle 1 is equipped with
The threaded hole of connection is threadedly engaged with threaded ends.
Regulating mechanism includes torsionspring 5 and reset spring 6, reset spring 5 be coated on connecting rod 3 and be set to handle 1 with
Between sleeve 2, one end of connecting rod 3 penetrates guide channel and is connect by torsionspring 5 with clamping jaw 4.It can specifically be connected in connecting rod
Through-hole is arranged in one end of clamping jaw, and clamping jaw (clamping jaw is made of two claws) head end is equally arranged through-hole, is connected by torsionspring
And be fixed together, clamping jaw being capable of flexible rotating after connecting connecting rod.
For the ease of the guiding movement of reset spring, above-mentioned tooling further includes the fixed frame for being oriented to fixed reset spring
Group, fixed frame group include the first guiding fixed frame 7 that opening direction is arranged oppositely and the second guiding fixed frame 8, the first fixed guide
Determine frame 7 and second guiding fixed frame 8 connect respectively with handle 1 and sleeve 2, the both ends of reset spring 6 respectively with the first fixed guide
Determine frame 7 to connect with the open bottom end of the second guiding fixed frame 8.Reset spring guarantee can return to initial shape using rear tooling every time
State, spring guiding fixed frame then guarantee the stabilization in reset spring elastic force direction.Two springs guiding fixed frames respectively with handle and
Together, stress is smaller is generally bonded with glue for connection at two for this for sleeve connection.
For the ease of as needed come set connecting rod and clamping jaw insertion sleeve after maximum height position, the middle part of connecting rod 3
Preferably thread segment 31, guide channel is interior to be equipped with the adjusting spiral shell for cooperating with thread segment and adjusting connecting rod 3 and the insertion sleeve portion of clamping jaw 4
Mother 9.Thread segment can be used standard pitch or fine pitch in order to the adjusting nut of screw-in can more accurately adjust connecting rod and
Position under clamping jaw free state.It is put into reset spring after two spring guiding fixed frame alignment, the threaded hole on handle is screwed into
The elastic force of connecting rod end thread, reset spring makes adjusting nut fit closely sleeve.
As a further improvement, the end of guide channel is preferably provided with the guiding arc that guided jaw 4 is oriented to sliding motion
Face, to constrain the sliding trajectory of clamping jaw.The head end of clamping jaw 4 is equipped with the plane for being bonded connecting rod, and the middle section distortion of clamping jaw is
Cooperate the arc shape of curved guiding surface.
