Abstract
The utility model relates to a tosecan, which comprises a chuck, a vertical column, a scribing pin and a locking nut. One end of the vertical column is connected with the chuck, and the vertical column is connected with the scribing pin through the locking nut. The tosecan is characterized in that an included angle ranging from 90 degrees to 120 degrees is formed by two clamping planes arranged on the inner wall of a hole which is positioned in the center of the chuck, the intersecting line of the two clamping planes on the chuck is homo-lateral to the vertical column, and a jack screw is arranged on the chuck opposite to the vertical column. Compared with the prior art, the tosecan has the advantages that firstly, scribing and aligning of work pieces can be completed by the aid of rotary centers on devices such as vertical lathes, horizontal lathes, boring machines and the like, secondly, machining precision and efficiency of flange holes and central shaft holes are effectively improved, and thirdly, the tosecan is simple in structure, low in manufacturing cost, simple and convenient in use and easy in popularization and application.
Description
Technical field
The utility model relates to field of machining, relates in particular to a kind of tosecan.
Background technology
At present in the machining after the centre bore of workpiece and end face machine, need a stroke centre bore periphery flange hole, the method at following definite center is generally arranged:
When 1) drawing centre bore peripheral flange hole; On platform, strip plank centre is nailed on iron sheet; Wood lath is sawn into than the long point of center bore summary, hammers in the centre bore, marks the center circle at flange hole place then with planing; This method generally makes center circle and workpiece centre hole coaxiality error 0.3~0.5mm, position error 0.5~0.7mm behind the branches such as flange hole.Center-hole diameter is generally filled in the centre bore with leads during less than 200mm, and other stroke method is the same.
2) to solid shafting or major axis platform class workpiece, be benchmark then with the axle cylindrical, on axial end, block the center with planing, plan with clubfoot then and mark the circle at each pore size distribution place.
For manufactured axle class, when needing again the machining center axis hole, conventional aligning method has in addition:
1) on hollow workpiece, squeezing earlier a template on the platform, be that benchmark is drawn the center with the cylindrical, adjust then centre frame make the center of drawing to the top center of last tailstock tool.
2) utilize on the centre frame coaxial mark with the lathe centres, with bow compass centering workpiece.
It is thus clear that the conventional scoring tool of above-mentioned use is to workpiece line, centering, the centralized positioning low precision, efficient is low, the quality requirement of the workpiece that is difficult to guarantee that precision is higher.
Summary of the invention
The purpose of the utility model provides a kind of tosecan, can rule and centering to workpiece by the pivot on the lathe, the low difficult problem of centralized positioning precision when solving workpiece line, centering.
For solving the problems of the technologies described above, the technical scheme of the utility model is:
A kind of tosecan; Comprise chuck, column, scriber, locking nut, column one end links to each other with chuck, and column is connected through locking nut with scriber; Said chuck hub is porose; The hole inwall is provided with two clamping planes that become angle, the intersecting lens on two clamping planes and column homonymy on the chuck, and the chuck of column offside is provided with jackscrew.
Said two clamping plane included angles are 90 °~120 °.
Compared with prior art, the beneficial effect of the utility model is: 1) can rule and centering to workpiece by means of the pivot on the equipment such as vertical lathe, horizontal lathe, boring machine.2) machining accuracy and the efficient of flange hole and central shaft hole have been improved effectively.3) simple in structure, cost of manufacture is low, and is easy to use, be easy to apply.
Description of drawings
Fig. 1 is the utility model example structure sketch map;
Fig. 2 is a workpiece end face flange hole line application examples on the boring machine;
Fig. 3 is a workpiece centering application examples on the horizontal lathe.
Among the figure: the 1-chuck 2-column 3-scriber 4-locking nut 5-clamping plane 6-jackscrew 7-boring spindle boring bar 8-workpiece one 9-Horizontal LaCommutating Center Rest 10-workpiece two 11-12-tail stock live center core 13-nut of planing
The specific embodiment
Be described further below in conjunction with the specific embodiment of accompanying drawing the utility model:
Seeing Fig. 1, is a kind of tosecan example structure of the utility model sketch map, comprises chuck 1, column 2, scriber 3, locking nut 4, and column 2 one ends link to each other with chuck 1 through nut 13, and column 2 is connected through locking nut 4 with scriber 3.Chuck 1 center is porose, and the hole inwall is provided with two clamping planes 5 that become 120 °, the intersecting lens on two clamping planes 5 and column 2 homonymies on the chuck 1, and the chuck 1 of column 2 offsides is provided with jackscrew 6.
Seeing Fig. 2, is workpiece end face flange hole line application examples on the boring machine, after accomplishing workpiece one 8 cylindricals and end face on the boring machine, tosecan chuck 1 is fixed on the boring spindle boring bar 7, and then the line center of scriber 3 is coaxial with machine tool chief axis.With the boring machine speed change to neutral; Hand steered tosecan column 2; Utilize the rotation of boring spindle, earlier 11 on workpiece one 8 end faces, mark the two section short arc lines approximate with the requirement of pattern diameter with planing, until plan 11 the circular arc of drawing rotate stroke full circle with scriber 3 with scriber 3 circular arc of drawing after tangent; This circle is exactly the flange hole center circle, and the center of this circle and workpiece axle center deviation are less than 0.05mm.
Seeing Fig. 3, is workpiece centering application examples on the horizontal lathe, when the workpiece 2 10 of axis hole to be processed carries out centering on to Horizontal LaCommutating Center Rest 9; Earlier tosecan chuck 1 is fixed on the tail stock live center core 12, scriber 3 is adjusted on workpiece 2 10 outer round surface, rotation scriber 3; Adjustment Horizontal LaCommutating Center Rest 9, with workpiece 2 10 centerings, workpiece does not change; The line dribbling scriber 3 around workpiece 2 10 rotation, thus 2 10 cylindricals of the workpiece behind the centering just and the main shaft of lathe coaxial.
