Abstract
The invention relates to a high-precision inclined hole drilling tool which comprises a base plate and a press block. A cambered surface is arranged on the base plate, the radian of the cambered surface is the same as the radian of an undersurface of a workpiece, a major positioning hole and a minor positioning hole are formed in the cambered surface, a long hole is formed in the press block, and a positioning bolt penetrates through the long hole and is matched with the major positioning hole. The high-precision inclined hole drilling tool is simple in structure, economic and practical, convenient to operate and high in machining precision.
Description
Technical field
The present invention relates to technical field of tooling clamps, particularly relating to a kind of positioning tool having rat holing on cambered surface workpiece.
Background technology
For the workpiece 1 with cambered surface 13 as shown in Figure 1, wherein through hole 11 is accomplished fluently, in order to the counterbore 12 concentric with through hole 11 can be got, higher to its positioning accuracy request, workpiece 1 own, with cambered surface 13, if use conventional localization method, is adding man-hour, workpiece 1 there will be the unstable phenomenon in location, causes machining accuracy undesirable.
Summary of the invention
The present invention is directed to above-mentioned shortcoming of the prior art, provide a kind of high-precision drilling inclined hole frock, its structure is simple, and economical and practical, easy to operate, machining accuracy is high.
The technical solution adopted in the present invention is as follows:
High-precision drilling inclined hole frock, comprises base plate and briquetting, and with cambered surface on base plate, the radian of cambered surface is identical with the radian of workpiece bottom, with large locating hole and little locating hole in cambered surface; With elongated hole on briquetting, bolt coordinates with large locating hole through elongated hole;
Further technical scheme is as follows:
The two side of described base plate is with locating slot;
Large locating hole in described cambered surface and the quantity of little locating hole are two;
Described large locating hole is inclined hole with little locating hole and direction is consistent.
The invention has the advantages that: on base plate, arrange the cambered surface identical with workpiece bottom radian, when positioning workpiece, location area is larger, being conducive to the stable of workpiece; Oblique locating hole is set in the cambered surface of base plate simultaneously, by alignment pin, workpiece is positioned, with bolt, briquetting is positioned on workpiece simultaneously, improve the positioning precision of workpiece, and then ensure the precision of boring; Structure of the present invention is simple, and economical and practical, easy to operate, machining accuracy is high.

Fig. 1 is the stereogram of workpiece.
Fig. 2 is the stereogram of base plate of the present invention.
Fig. 3 is the stereogram of the present invention when using.
Fig. 4 is the front sectional view of Fig. 3.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figures 1 to 4, the present invention includes base plate 2 and briquetting 3, with cambered surface 24 on base plate 2, the radian of cambered surface 24 is identical with the radian of workpiece 1 bottom surface 13, so can ensure that there is larger contact area the bottom surface 13 of workpiece 1 with cambered surface 24, be conducive to the stable position of workpiece 1; With large locating hole 21 and each two of little locating hole 22 in cambered surface 24, large locating hole 21 is tilting with little locating hole 22 and direction is consistent, and placement positioning pin 5 in little locating hole 22, positions workpiece 1, base plate 2, with locating slot 23, can be fixed on the table by the two side of base plate 2; With elongated hole 31 on briquetting 3, be conducive to briquetting 3 and adjust position location, bolt 4 coordinates with large locating hole 21 through elongated hole 31, is fixed, makes briquetting 3 workpiece pressing 1 to briquetting 3;
Using method of the present invention is as follows:
The first step, is alignd the through hole 11 on workpiece 1 with the little locating hole 22 in base plate 2 cambered surface 24, is located by workpiece 1 by alignment pin 5;
Second step, is pressed in briquetting 3 on the boss 14 of workpiece 1, locates fixing by bolt 4 and large locating hole 21 by briquetting 3;
3rd step, after being had good positioning by workpiece 1, at through hole 11, place processes counterbore 12, and because the bottom surface 13 of workpiece 1 is identical with the radian of base plate 14, boss 14 end face on workpiece 1 is in non-standard state, and drill bit is in vertical state, and the counterbore 12 processed is also for oblique.
More than describing is explanation of the invention, and be not the restriction to invention, limited range of the present invention, see claim, within protection scope of the present invention, can do any type of amendment.
