Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, the utility model comprises stop collar 2 and is positioned at the driving key 1 of stop collar 2, stop collar 2 afterbody (Fig. 1 upper end) has the coaxial driving hole 3 corresponding with spanner 15 convex head, head (Fig. 1 lower end) has the coaxial cylindrical counterbore 4 corresponding with camshaft 13 external diameter, drive key 1 shape to be corresponding with counterbore 4 cylindrical, and be fixedly connected with stop collar 2 in counterbore 4.As shown in Figure 2, camshaft 13 has keyway 14, keyway 14 can open circumferentially or camshaft 13 inner, in the present embodiment, keyway 14 leaves at camshaft 13 circumferentially, drives key 1 outer face to be provided with the projection 5 corresponding with keyway 14 on camshaft 13.
The driving hole 3 of stop collar 2 rearwardly borehole enlargement extends to form stepped hole, offer the installation counterbore 6 be communicated with counterbore 4 towards stop collar 2 afterbody at the bottom of driving hole 3 hole, drive on key 1 and have the axial screw 7 corresponding with installing counterbore 6, bolt 8 enters through installation counterbore 6 from driving hole 3 and is connected with stop collar 2 by driving key 1 with screw 7.Drive between key 1 and stop collar 2 and be provided with axial circular cylindricality spacer pin 9 (being not limited to cylindrical), key 1 is driven to be provided with the first axial pin-and-hole 10 with stop collar 2 end face junction, stop collar 2 with axially the second pin-and-hole 11 driving key 1 end face junction to be provided with, first pin-and-hole 10 and the second pin-and-hole 11 opening overlap the space that formed and spacer pin 9 shape corresponding, spacer pin 9 two ends lay respectively in the first pin-and-hole 10 and the second pin-and-hole 11.By alignment pin 9 and bolt 8 driving key 1 to be connected with stop collar 2 and spacing.
Driving hole 3 is corresponding with spanner 15 convex head, adopt head with the spanner 15 of protruding square head or six square toes, driving hole 3 is positive square or orthohexagonal, in the present embodiment, spanner 15 is the ratchet spanner of band square head, ratchet spanner square head is provided with protruding spacing ball, and on stop collar 2, radial direction has the spacing hole 12 coordinated with spacing ball.The square head of spanner 15 projection inserted in corresponding driving hole 3, spacing ball enters spacing hole 12 and the square head of spanner 15 is positioned.
Using method of the present utility model is: inserted by spacer pin 9 in first pin-and-hole 10 and the second pin-and-hole 11 and driving key 1, stop collar 2 are combined, through installation counterbore 6 and screw 7, driving key 1 and stop collar 2 are connected into manual rotation camshaft device by bolt 8; Driving hole 3 corresponding for the insertion of the square head of spanner 15 projection, spacing ball are entered in spacing hole 12 and form entirety, be installed in the keyway 14 of camshaft 13 by protruding 5 again, now counterbore 4 and camshaft 13 major diameter fit, shake spanner 15, can realize the manual rotation of camshaft 13.When spanner 15 is ratchet spanner, by the direction adjustment knob of ratchet spanner, can also easily realize the rotation of camshaft 13 different directions.
If processing conditions allows, can by one-body molded with stop collar 2 for driving key 1, directly in counterbore 4, arrange protruding 5, but it is very difficult that existing processing conditions processes projection in hole, use driving key 1 of the present utility model, stop collar 2 coordinate, the processing of driving key 1 end face protruding 50 points easily, and after damaging, replaceable driving key 1 is newly placed in former stop collar 2, this fit structure can save material, increases service life.
