Description
Technical field
The utility model relates to a kind of hole back gauge chalker, relates in particular to a kind of hand-held hole back gauge Quick scribing device.
Background technology
At part edge, drill row's pilot hole, the position of drilling is drawn position, hole cross centre line at piece surface with pencil by operating personnel, and the center line in hole directly affects the accurate of subsequent openings position to the accuracy of the back gauge distance of part edge.The line mode that general operation personnel take is hand-held pencil, and with middle finger, near part edge, mobile arm, drives pencil in extremely rapid succession to draw a back gauge line parallel with part edge at piece surface; Or the mode combining with pencil with Steel Ruler draws the back gauge line parallel with part edge at piece surface.First kind of way is due to pencil axis and piece surface out of plumb, the lines that draw are thicker, affect follow-up drilling centering, and be to point near part edge in the process of mobile line, the back gauge line parallel degree drawing is poor, inaccurate, operating personnel individual's technical merit is had relatively high expectations simultaneously; The second way needs multi-pass operation just can complete longer back gauge line for larger part, and line efficiency is extremely low.
Summary of the invention
In order to solve, the line that prior art exists is inaccurate, the inefficient problem of ruling, and the utility model provides hand-held hole back gauge chalker.Hand-held of the present utility model hole back gauge chalker comprises bow pen, clamper, main body, mobile support saddle, adjustment screw, end cap, the locating surface of being close to part edge when described main body left side is provided with line, in the middle of main body, have a guide rail hole that runs through total length, described mobile support saddle one end is connected with the clamper of clamping bow pen, mobile support saddle has waist through hole, the mobile support saddle other end has screwed hole and is placed in the guide rail hole of main body left end, described screwed hole is communicated with waist through hole, left section of periphery of described adjustment screw is shaped with screw thread, right section is the shank for hand-turning, described adjustment screw middle part is a ring flange, described ring flange diameter is greater than guide rail hole, adjustment screw is placed in main body right-hand member guide rail hole, left section of adjustment screw is screwed onto on mobile support saddle, there is the corresponding cavity that holds ring flange described end cap inner side, end cap has through hole, end cap is sleeved on the shank of right section of described adjustment screw and is connected in main body right-hand member.
Described clamper comprises collet and nut, described collet be one axially have some breach, thin-wall barrel, on described mobile support saddle, be provided with perpendicular to the axial installing hole of guide rail hole, in installing hole, be provided with the corresponding taper hole section of male cone (strobilus masculinus) with collet, described collet is contained in installing hole, described nut has the corresponding taper hole of male cone (strobilus masculinus) with collet, nut be screwed onto installing hole one end on mobile support saddle, described bow pen is contained in the collet of clamper.
Described mobile support saddle upper surface is shaped with graduation mark.
The guide rail hole matched in clearance of described mobile support saddle and main body, quality of fit is H9/e9.
Right section of shank of described adjustment screw is shaped with and is beneficial to hand-held reticulate pattern.
The external screw thread of described adjustment screw and the internal thread of mobile support saddle are selected fine thread.
The utility model has following good effect than prior art, hand-held of the present utility model hole back gauge chalker, during line, bow pen is packed in collet, by adjustment screw, reconcile the overhang of mobile support saddle, reach behind tram, with main body left end locating surface, be close to part edge, with bow pen, be close to piece surface, and slightly bow pen is applied to certain axial force, hand-held device is along part edge fast moving, just can mark the back gauge line that is parallel to part edge at piece surface, therefore the efficiency of ruling is high, because adjustment screw can effectively prevent the front and back play of mobile support saddle in scratching process, mobile support saddle is provided with graduation mark can read adjustment distance easily, therefore line accurately, collet clamping bow pen, can make bow pen quick-replaceable.
