Abstract
The utility model relates to a casting tapping location clamp and belongs to the technical field of location clamps. The casting tapping location clamp is characterized by comprising a back plate (1), a base plate (3) and two lateral plates (2). The back plate (1) is fixed on a machine tool, the upper plane of the base plate (3) is fixedly connected with a workpiece, and a straight line passing through the circle center of a hole to be tapped of the workpiece and parallel to the base plate (3) intersect with the axis of a machine tool rotating shaft, a first stopping block (4), a second stopping block (5) and a third stopping block (6) are further fixed on the base plate (3), the first stopping block (4) and the second stopping block (5) clamp the outer diameter of the hole to be tapped, and the third stopping block (6) abuts against the workpiece. Concentricity of the axis of the hole to be tapped and the axis of the machine tool rotating shaft can be ensured by simply adjusting the position of the workpiece on the base plate (3).
Description
Technical field
The utility model relates to a kind of foundry goods tapping positioning fixture, belongs to positioning fixture technical field.
Background technology
Fixture is to add to be used for rapid fastening workpiece man-hour, makes lathe, cutter, workpiece keep the process unit of correct relative position.Frock clamp is the indispensable parts of machining, machine tool technology at a high speed, under the drive of efficient, accurate, compound, intelligent, environmental protection future development, clamp technology is just towards high-precision, efficient, module, combination, general, economic future development.
But existing precision casting is different, on some precision casting, be also provided with through hole, some through hole also needs tapping, therefore, and during tapping, need to guarantee to treat that tapping through hole and lathe rotating shaft reach necessary axiality, otherwise easily cause tapping failure, cause workpiece to scrap.
Yet, due to the features of shape of some workpiece, cause coaxial fixing more difficultly, this just needs special-purpose positioning fixture to be fixed.Existing positioning fixture, accurate positioning is not good, and stability is not good yet, causes axiality not enough, and tapping scrappage is high, and workpiece dismounting is also inconvenient.
Summary of the invention
The utility model technical issues that need to address are: existing foundry goods, carrying out Dui Qishang hole while carrying out tapping, and the axiality of workpiece and lathe rotating shaft is difficult to guarantee, and accurate positioning, stability are not good, cause workpiece scrappage high, and dismounting is also inconvenient.
The utility model is taked following technical scheme:
A kind of foundry goods tapping positioning fixture, comprise backboard 1, base plate 3 and two blocks of side plates 2, described backboard 1 is fixed on lathe, the upper plane of described base plate 3 is fixedly connected with workpiece, cross described workpiece treat the tapping Kong center of circle and the straight line parallel with base plate 3 crossing with the axial line of lathe rotating shaft; On described base plate 3, be also fixed with first, second and third block 4,5,6, described first and second block 4,5 treats that by described the external diameter in tapping hole clamps, and described the 3rd block 6 props up described workpiece.
The feature of the technical program is, by this positioning fixture is fixed on machine tool, the position of backboard 1 vertical with lathe rotating shaft over against,, workpiece is placed on base plate 3 meanwhile, the bottom surface of workpiece and base plate 3 laminatings, guaranteed to treat the tapping hole circle heart and the straight line parallel with base plate 3, intersected with the axial line of lathe rotating shaft, therefore, only need to adjust workpiece in base plate 3 Shang positions, just can guarantee to treat the axiality in the axle center of tapping Kong axle center and lathe rotating shaft.
Further, on described first and second block, be equipped with fastening bolt, a pair of fastening bolt treats that by described the external diameter in tapping hole is fixedly clamped.Guarantee the firmness of workpiece location.
Further, described the 3rd block 6 is connected with base plate 3 by a bolt.Further guarantee the firmness of workpiece location.
Further, described positioning fixture adopts stainless steel.
Further, described side plate 2 is triangular in shape, and two sides are fastenedly connected with base plate 3 and backboard 1 respectively.Thereby the rigidity intensity of whole positioning fixture is improved.
The beneficial effects of the utility model are:
1) greatly improve workpiece and treated the axiality between tapping hole and lathe rotating shaft, guaranteed the precision of processing.
2) accurate positioning, good stability, has reduced the scrappage of workpiece.
3) workpiece dismounting location is convenient, has reduced machine operation person's labour intensity.

The specific embodiment
Below in conjunction with specific embodiment, the utility model is further illustrated.
A kind of foundry goods tapping positioning fixture, adopt stainless steel, comprise backboard 1, base plate 3 and two blocks of side plates 2, described backboard 1 is fixed on lathe, the upper plane of described base plate 3 is fixedly connected with workpiece, cross described workpiece treat the tapping Kong center of circle and the straight line parallel with base plate 3 crossing with the axial line of lathe rotating shaft; On described base plate 3, be also fixed with first, second and third block 4,5,6, described first and second block 4,5 treats that by described the external diameter in tapping hole clamps, and described the 3rd block 6 props up described workpiece.
On described first and second block, be equipped with fastening bolt, a pair of fastening bolt treats that by described the external diameter in tapping hole is fixedly clamped.Guarantee the firmness of workpiece location.
Described the 3rd block 6 is connected with base plate 3 by a bolt.Further guarantee the firmness of workpiece location.
Described side plate 2 is triangular in shape, and two sides are fastenedly connected with base plate 3 and backboard 1 respectively.Thereby the rigidity intensity of whole positioning fixture is improved.
While specifically operating, this positioning fixture is fixed on machine tool, the position of backboard 1 vertical with lathe rotating shaft over against,, workpiece is placed on base plate 3 meanwhile, the bottom surface of workpiece and base plate 3 laminatings, guaranteed to treat the tapping hole circle heart and the straight line parallel with base plate 3, intersected with the axial line of lathe rotating shaft, therefore, only need to adjust workpiece and be fitted in base plate 3 Shang positions, just can guarantee to treat the axiality in the axle center of tapping Kong axle center and lathe rotating shaft.
