An outer circle of the positioning column is provided with a first step, a second step and a stopping shoulder, the end face of the positioning column is provided with a first mounting hole, a second mounting hole is arranged in the positioning column, the bottom and the top end of the second mounting hole are provided with a threaded section and a cone-shaped section respectively, the outer circle of the positioning column is communicated with the second mounting hole through an open groove, the top block is provided with a cone-shaped table, and the top end of the top block is provided with a tip groove and a third mounting hole. The cylindrical turning positioning tool is simple in structure, flexible and convenient to use and high in processing precision and has clamping simplicity.
Description
Technical field
The present invention relates to technical field of tooling clamps, relate in particular to the positioner that cylinder workpiece is carried out to turning processing.
Background technology
Field of machining, belongs to conventional processing technology at the enterprising driving Excircle machining of cylinder workpiece, but for the workpiece that has specific (special) requirements, uses common positioning tool to be difficult to reach required precision.
Summary of the invention
The present invention is directed to above-mentioned shortcoming of the prior art, a kind of turning positioning tool is provided, it is simple in structure, flexible and convenient to use, and clamping is simple, and machining accuracy is high.
The technical solution adopted in the present invention is as follows:
Turning positioning tool, comprise locating dowel and jacking block, locating dowel cylindrical is with first step, second step and shoulder block, the end face of locating dowel is with the first installing hole, locating dowel is interior with the second installing hole, the bottom of described the second installing hole and top are respectively thread segment and conical section, and the cylindrical of locating dowel is communicated with described the second installing hole by fluting; Jacking block is with taper platform, and the top of jacking block is with top groove and the 3rd installing hole.
The invention has the advantages that: the cylindrical of locating dowel and the inner circle of workpiece matches and spacing by the shoulder block in locating dowel; The cylindrical of locating dowel is communicated with the installing hole in it by fluting, while adding cartridge screw from installing hole, it is large that the outside diameter of locating dowel becomes, workpiece is carried out to stretching, be equipped with jacking block simultaneously and coordinate and be connected with the interior nose end of locating dowel, lathe top heads in the top groove of jacking block end face workpiece clamped, simple in structure, convenient mounting and clamping, machining accuracy is high.
Accompanying drawing explanation
Fig. 1 is the full sectional view of locating dowel of the present invention.
Fig. 2 is the full sectional view of jacking block of the present invention.
Fig. 3 is the mated condition figure of locating dowel of the present invention and workpiece.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1 to Figure 3, the present invention includes locating dowel 1 and jacking block 2, locating dowel 1 cylindrical is with first step 16, second step 17 and shoulder block 15, first step 16, second step 17 coordinates with the inner circle of workpiece 3, shoulder block 15 coordinates with the end face of workpiece 3 the spacing effect of playing, the end face of locating dowel 1 is with the first installing hole 14, locating dowel 1 is interior with the second installing hole, the bottom of described the second installing hole and top are respectively thread segment 11 and conical section 12, the cylindrical of locating dowel 1 13 is communicated with described the second installing hole by slotting, when thread segment 11 packs sunk screw into, the outside distending of cylindrical meeting of locating dowel 1, form the cylindrical of bullet, jacking block 2 is with taper platform 21, when assembling is used, taper platform 21 with in locating dowel 1 described in the conical section 12 of the second installing hole coordinate, the top of jacking block 2 is with top groove 23 and the 3rd installing hole 22, in top groove 23, lathe can be inserted top, during use, two locating dowels 1 are carried out clamping and positioning from the two ends of workpiece 3 to it, and jacking block 2 is connected with locating dowel 1 by the first installing hole 14 in the 3rd installing hole and locating dowel 1,
Using method of the present invention is as follows:
The first step, packs two locating dowels 1 into respectively from the two ends of workpiece 3, the shoulder block 15 of locating dowel 1 and the end face of workpiece 3 are offseted;
Second step, the thread segment 11 bottom the second installing hole of locating dowel 1 is installed sunk screws and tightens, and makes the cylindrical of locating dowel 1 slightly swollen, and it is large that external diameter becomes, and makes the cylindrical of locating dowel 1 and the inner circle of workpiece 3 coordinate tighter;
The 3rd step, packs jacking block 2 in the second installing hole of locating dowel 1, and the taper platform 21 of jacking block 2 and the conical section 12 of the second installing hole are coordinated, and jacking block and locating dowel 1 is connected by the 3rd installing hole of jacking block 2 and the first installing hole 14 in locating dowel 1 with screw;
The 4th step, is clamped in clamping locating dowel 1, jacking block 2 and workpiece 3 on lathe, makes, in the top top groove 23 that withstands on jacking block 2 of lathe, to start lathe workpiece 3 is carried out to turning processing.
More than describing is explanation of the invention, is not the restriction to invention, and limited range of the present invention, referring to claim, within protection scope of the present invention, can be done any type of modification.
