Cambered surface bores diplopore positioning tool
The present invention relates to technical field of tooling clamps, particularly relate to the positioning fixture for carrying out Drilling operation to workpiece.
Workpiece 1 as shown in Figure 1, it is an irregular annular workpieces, but also with fluting, its centre bore 11 is ellipticity, also with cambered surface 12 on workpiece 1, now to process the through hole 13 vertical with cambered surface 12 in cambered surface 12, use plain clamp to acquire a certain degree of difficulty to its location, especially will ensure machining accuracy, special frock must be used just to meet the demands, and frock must be easy to use, clamping efficiency is high, can ensure its machining accuracy again simultaneously.
Summary of the invention
The present invention is directed to above-mentioned shortcoming of the prior art, provide a kind of cambered surface to bore diplopore positioning tool, its structure is simple, and flexible and convenient to use, clamping efficiency is high, and machining accuracy is high.
The technical solution adopted in the present invention is as follows:
Cambered surface bores diplopore positioning tool, and comprise bucking ladder, with L shape positioning table on bucking ladder, with locating dowel on positioning table, locating dowel cylindrical is with rectangular block; Positioning table is positioned at for arcwall face above locating dowel, on positioning table in the normal direction of described arcwall face with drill jig; Bucking ladder is positioned at chute below locating dowel, chute is built with forked tail platform, and forked tail platform is fixed on the bottom of U-shaped support, and the both sides of support are all with screw.
The invention has the advantages that: according to the structure of workpiece, positioning table is arranged the locating dowel coordinated with workpiece center hole, support is set on bucking ladder simultaneously, screw on it clamps the fluting place on workpiece, positioning table arranges arcwall face, and in the normal direction of arcwall face, drill jig is installed, by the cambered surface hole of drill jig at workpiece, diplopore can be processed efficiently by tilting in the lateral direction for bucking ladder, do not need to carry out repeated clamping location to workpiece, structure is simple, flexible and convenient to use, clamping efficiency is high, and machining accuracy is high.

Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1 to Figure 2, the present invention includes bucking ladder 2, with L shape positioning table 3 on bucking ladder 2, with locating dowel 4 on positioning table 3, positioning table 4 coordinates with the center grooved hole 11 on workpiece 1, and locating dowel 4 cylindrical is with rectangular block 5, during locating and machining, the fluting place of workpiece 1 is sandwiched in rectangular block 5 both sides, positioning table 3 is positioned at above locating dowel 4 is arcwall face, the radian of described arcwall face is identical with the radian of the cambered surface 12 on workpiece 1, during working timing, the cambered surface 12 of workpiece 1 can be close on the described arcwall face on positioning table 3, on positioning table 3 in the normal direction of described arcwall face with drill jig 6, when the cambered surface 12 of workpiece 1 fits in the described arcwall face of positioning table 3, the through hole 13 vertical with cambered surface 12 can be processed, bucking ladder 2 is positioned at below locating dowel 4 with chute 7, chute 7 is built with forked tail platform 9, forked tail platform 9 is fixed on the bottom of U-shaped support 8, the both sides of support 8 are all with screw 10, U-shaped support 8 can move horizontally along chute 7 with forked tail platform 9, when U-shaped support 8 moves to below locating dowel 4, fluting place on workpiece 1 can grip on rectangular block 5 by tightening screw 10, accurate Set and Positioning is completed to workpiece 1, during Drilling operation, first bucking ladder 2 inclined-plane is contacted with operating desk, one of them drill jig 6 is in vertical state, complete the processing in first hole, in the same way, the processing in second hole can be completed, efficiency is high, machining accuracy is high,
Using method of the present invention is as follows:
The first step, coordinates the center grooved hole 11 of workpiece 1 with positioning table 4;
Second step, makes the fluting place of workpiece 1 be sandwiched on rectangular block 5;
3rd step, regulate U-shaped support 8 position, the fluting place of workpiece 1 is clamped in rectangular block 5 both sides by tightening screw 10;
4th step, first contacts bucking ladder 2 inclined-plane with operating desk, and one of them drill jig 6, in vertical state, completes the processing of first through hole 13, in the same way, can complete the processing of second through hole 13.
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.
