Description
Technical field
The utility model relates to technical field of tooling clamps, relates in particular to and structure is carried out to the positioning tool of turning processing compared with complex part.
Background technology
Workpiece 1 as shown in Figure 1, its bottom is a disk, because workpiece 1 is to obtain by casting, the cylindrical of disk 11 is comparatively coarse, now need to carry out turning processing to it, but because the disk 11 of workpiece 1 is not suitable for directly using scroll chuck to position, and it also has tetragonal boss 13, on boss 13 with center counterbore 12, if will realize the accurate location to it, must use special tooling, otherwise positioning precision and machining accuracy are all difficult to guarantee.
Utility model content
The utility model, for above-mentioned shortcoming of the prior art, provides a kind of complex part efficient turning positioning tool, and it is simple in structure, flexible and convenient to use, and clamping efficiency is high, and machining accuracy is high.
The technical scheme that the utility model adopts is as follows:
The efficient turning positioning tool of complex part, comprises the first positioning seat and the second positioning seat; The first positioning seat is with the first gripping section, the first gripping section end first positioning disk that is connected, the center of the first positioning disk is with counterbore, in counterbore with the first locating dowel; The second positioning seat is with the second gripping section, the second gripping section end second positioning disk that is connected, on the second positioning disk with the second locating dowel.
The utility model has the advantage of: use two positioning seats from former and later two directions of workpiece, it to be positioned respectively, the structure of positioning seat is corresponding with the structure of workpiece, by positioning seat is fixed on lathe workpiece is machined, simple in structure, flexible and convenient to use, clamping efficiency is high, and machining accuracy is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of workpiece.
Fig. 2 is the structural representation of the first positioning seat of the present utility model.
Fig. 3 is the structural representation of the second positioning seat of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
As shown in figures 1 and 3, the utility model comprises the first positioning seat 2 and the second positioning seat 3; The first positioning seat 2 is with the first gripping section 21, for the scroll chuck to lathe by the first positioning seat 2 clampings, the first gripping section 21 ends first positioning disk 22 that is connected, the first positioning disk 22 center is with counterbore 23, the cylindrical of the tetragonal boss 13 of the inner circle of counterbore 23 and workpiece 1 matches, in counterbore 23, with the first locating dowel 24, the size of locating dowel 24 and tetragonal boss 13Shang center counterbore 12 are measure-alike, can guarantee that the first positioning seat 2 accurately locates from the front of workpiece 1; The second positioning seat 3 is with the second gripping section 31, on the second gripping section 31 with bellmouth, can facilitate lathe seat to carry out clamping to it, the second gripping section 31 ends second positioning disk 32 that is connected, the disk 11 of the second 32 pairs of positioning disks workpiece, 1 bottom carries out supporting and location, on the second positioning disk 32, with the second locating dowel 33, during clamping, the second locating dowel 33 is positioned at the locating hole on the disk 11 of workpiece 1;
Using method of the present utility model is as follows:
The first step, the first positioning seat 2 clampings to the scroll chuck of lathe;
Second step, coordinates workpiece 1 with the first positioning seat 2, even if the first locating dowel 24 is inserted in the center counterbore 12 of workpiece 1;
The 3rd step, coordinates the second positioning seat 3 with the bottom disc 11 of workpiece 1, even in the described locating hole that the second locating dowel 33 is inserted on disk 11;
The 4th step, the tailstock centre of lathe withstands the second gripping section 31 on the second positioning seat 3;
The 5th step, starts lathe the disk 11 of workpiece 1 is carried out to turning processing.
More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range, referring to claim, within protection domain of the present utility model, can be done any type of modification.
