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, relate in particular to a kind of positioning tool having rat holing on the cambered surface workpiece.
Background technology
For the workpiece 1 with cambered surface 13 as shown in Figure 1, wherein through hole 11 has been accomplished fluently, in order to get the counterbore 12 concentric with through hole 11, positioning accuracy request to it is higher, workpiece 1 own if use conventional localization method, is adding man-hour with cambered surface 13, the unstable phenomenon in location can appear in workpiece 1, causes machining accuracy undesirable.
Summary of the invention
The present invention is directed to above-mentioned shortcoming of the prior art, a kind of high-precision drilling inclined hole frock is provided, it is simple in structure, and is economical and practical, easy to operate, and 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 on base plate, with cambered surface, the radian of cambered surface is identical with the radian of workpiece bottom, on cambered surface with large locating hole and little locating hole; On briquetting, with elongated hole, bolt passes elongated hole and coordinates with large locating hole;
Further technical scheme is as follows:
The two side of described base plate is with locating slot;
Large locating hole on 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: the cambered surface identical with the workpiece bottom radian is set on base plate, and when workpiece was positioned, location area was larger, was conducive to the stable of workpiece; Simultaneously oblique locating hole is set on the cambered surface of base plate, by alignment pin, workpiece is positioned, with bolt, briquetting is positioned on workpiece simultaneously, improve the positioning accuracy of workpiece, and then guarantee the precision of boring; The present invention is simple in structure, and is economical and practical, easy to operate, and machining accuracy is high.
Description of drawings
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 that the master of Fig. 3 looks cutaway view.
The specific embodiment
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, on base plate 2, with cambered surface 24, the radian of cambered surface 24 is identical with the radian of workpiece 1 bottom surface 13, there is larger contact area the bottom surface 13 that so can guarantee workpiece 1 with cambered surface 24, is conducive to the stable position of workpiece 1; On cambered surface 24 with large locating hole 21 and little locating hole 22 each two, large locating hole 21 and little locating hole 22 be tilting and direction consistent, the interior placement positioning pin 5 of little locating hole 22 positions workpiece 1, the two side of base plate 2 can be fixed on base plate 2 on workbench with locating slot 23; With elongated hole 31, be conducive to briquetting 3 and adjust the position location on briquetting 3, bolt 4 passes elongated hole 31 and coordinates with large locating hole 21, and briquetting 3 is fixed, and makes briquetting 3 workpiece pressings 1;
Using method of the present invention is as follows:
The first step is alignd the through hole 11 on workpiece 1 with little locating hole 22 on base plate 2 cambered surfaces 24, by alignment pin 5 with workpiece 1 location;
Second step is pressed in briquetting 3 on the boss 14 of workpiece 1, locates briquetting 3 fixing by bolt 4 and large locating hole 21;
In the 3rd step, after workpiece 1 was had good positioning, 11 places processed counterbore 12 at through hole, and because the bottom surface 13 of workpiece 1 is identical with the radian of base plate 14, boss 14 end faces on workpiece 1 are in non-standard state, and drill bit is in vertical state, and the counterbore 12 that processes is also for oblique.
Above description is explanation of the invention, is not that limited range of the present invention within protection scope of the present invention, can be done any type of modification referring to claim to the restriction of invention.
