Abstract

The utility model relates to a positioning tool for drilling two holes in a cambered surface. The positioning tool comprises a trapezoid table, wherein an L-shaped positioning table is arranged on the trapezoid table; a positioning column is arranged on the positioning table; a rectangular block is arranged on the external circle of the positioning column; a part, which is positioned above the positioning column, on the positioning table is a cambered surface; a drill jig is arranged on the positioning table along the normal direction of the cambered surface; a sliding chute is formed in a position, which is positioned below the positioning column, on the trapezoid table; a dovetail table is arranged in the sliding chute and is fixedly connected to the bottom of a U-shaped bracket; screws are arranged on two sides of the bracket. The positioning tool for drilling the two holes in the cambered surface is simple in structure, is used flexibly and conveniently, can realize clamping easily and is high in processing precision.

Description

Cambered surface is bored diplopore positioning tool

Technical field

The utility model relates to technical field of tooling clamps, relates in particular to for workpiece being carried out to the positioning fixture of Drilling operation.

Background technology

Workpiece 1 as shown in Figure 1, it is an irregular annular workpieces, but also with fluting, its centre bore 11 is ellipticity, on workpiece 1 also with cambered surface 12, now in cambered surface 12, process the through hole vertical with cambered surface 12 13, use plain clamp to acquire a certain degree of difficulty to its location, especially will guarantee machining accuracy, must use special-purpose frock just can meet the demands, and frock must be easy to use, clamping efficiency is high, can guarantee its machining accuracy again simultaneously.

Utility model content

The utility model, for above-mentioned shortcoming of the prior art, provides a kind of cambered surface to bore diplopore 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:

Cambered surface is bored diplopore positioning tool, comprises bucking ladder, and on bucking ladder, with L shaped positioning table, on positioning table, with locating dowel, locating dowel cylindrical is with rectangular block; On positioning table, be positioned at locating dowel top for arcwall face, on positioning table in the normal direction of described arcwall face with drill jig; On bucking ladder, be positioned at locating dowel below with chute, forked tail platform is housed in chute, forked tail platform is fixed on the bottom of U-shaped support, and the both sides of support are all with screw.

The utility model has the advantage of: according to the structure of workpiece, the locating dowel coordinating with workpiece center hole is set on positioning table, support is set simultaneously on bucking ladder, screw on it clamps the fluting place on workpiece, arcwall face is set on positioning table, and in the normal direction of arcwall face, drill jig is installed, cambered surface hole by drill jig at workpiece, by bucking ladder, direction is tilting to the left and right can process efficiently diplopore, do not need workpiece to carry out repeated clamping location, 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 structural representation 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 Figure 1 to Figure 2, the utility model comprises bucking ladder 2, on bucking ladder 2 with L shaped positioning table 3, on positioning table 3 with locating dowel 4, positioning table 4 coordinates with the center grooved hole 11 on workpiece 1, locating dowel 4 cylindricals are with rectangular block 5, and during processing location, the fluting place of workpiece 1 is sandwiched in rectangular block 5 both sides, on positioning table 3, being positioned at locating dowel 4 tops is arcwall face, the radian of described arcwall face is identical with the radian of 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, can process the through hole vertical with cambered surface 12 11, on bucking ladder 2, be positioned at locating dowel 4 belows with chute 7, forked tail platform 9 is housed in chute 7, 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 locating dowel 4 below, screwing screw 10 can grip the fluting place on workpiece 1 on rectangular block 5, workpiece 1 is completed to accurate clamping location, during Drilling operation, first an inclined-plane of bucking ladder 2 is contacted with operating desk, one of them drill jig 6 is vertical state, complete the processing in first hole, in the same way, can complete the processing in second hole, efficiency is high, machining accuracy is high,

Using method of the present utility model is as follows:

The first step, coordinates the center grooved hole 11 of workpiece 1 with positioning table 4;

Second step, is sandwiched on rectangular block 5 the fluting place of workpiece 1;

The 3rd step, regulates U-shaped support 8 positions, screws screw 10 the fluting place of workpiece 1 is clamped in to rectangular block 5 both sides;

The 4th step, first contacts an inclined-plane of bucking ladder 2 with operating desk, one of them drill jig 6 is 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 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.
