Described cylindrical sleeves endoporus is staircase structural model, technique hole when wherein aperture is adjustment screw dismounting, and macropore and adjustment screw head are matched in clearance.
Described scriber one end head is acicular texture, and for centering part end face, other end head is folding acicular texture, for the cylindrical of centering part.
The adjustment of scriber height:
The utility model is not when adjusting nut has complete pretension, breathing groove on chuck is in free state, chuck can realize non-resistance and move on slide bar, adjusting nut is when complete pretension, breathing groove on chuck is in impaction state, the relative position of chuck on slide bar is fixed, and can complete the adjustment of scriber height, thus meets axle, the cylindrical of pipe part, the end face centering of different size specification.
The adjustment of scriber angle and length:
The utility model is not when adjusting nut has complete pretension; adjustment screw is in relative free state; can to rotate or at axial trace movement; the rotation of adjustment screw can drive scriber around the rotation of adjustment screw axis; chuck also can rotate along slide bar axis in addition, thus realizes the rotation of scriber along slide bar axis; The axial trace movement of adjustment screw can ensure to thread a needle the maximal clearance of hole and third through-hole, thus realizes the adjustment of scriber length, and adjusting nut, when complete pretension, realizes the fixing of scriber angle and length.
The utility model, by the adjustment of adjusting nut, can realize the change of scriber height, angle and length, thus meets the part outer of different size specification, the centering of end face.
Use of the present utility model, solves the rough turn centering difficult problem that determines of factor completely artificially, also makes centering operation have intuitive and Statistical simultaneously, thus ensure that the rough turn precision of part, improve working (machining) efficiency.

Detailed description of the invention
The utility model comprises: base 1, slide bar 2, cylindrical sleeves 3, adjustment screw 4, chuck 5, scriber 6, plain washer 7, spring washer 8, adjusting nut 9.
Base 1: tetragonal body structure, is provided with screwed hole and room;
Slide bar 2: one end is provided with external screw thread, is connected with base 1 upper screwed hole, and slide bar 2 and the first through hole 10 matched in clearance on chuck 5, chuck 5 can move on slide bar 2.
Cylindrical sleeves 3: cylindrical structural, cylindrical sleeves 3 is provided with step inner hole structure, technique hole when wherein aperture 14 is adjustment screw 4 dismounting, and macropore 15 and adjustment screw 4 head assemble; Circumferentially be provided with hole 13 of threading a needle, hole 13 of threading a needle is assembled with scriber 6.
Adjustment screw 4: head is circumferentially provided with third through-hole, end is provided with screw thread, and the macropore 15 on its head cylindrical and cylindrical sleeves 3 assembles.
Chuck 5: chuck 5 two mutually perpendicular is respectively equipped with the first through hole 10 and the second through hole 11, the face at the first through hole 10 place is provided with breathing groove 12, and breathing groove originates in the first through hole 10, and runs through the second through hole 11, breathing groove 12 is convenient to install and slide, and its width is 1-2mm.
Scriber 6: scriber 6 one end is sharp acicular texture, for centering part end face, the other end is folding acicular texture, for the cylindrical of centering part.
Adjusting nut 9: step column structure, is provided with step endoporus, and wherein aperture is screwed hole, and macropore is through hole, and screwed hole is connected with adjustment screw 4, and through hole is stepping down of attachment screw 4 extension.
