Description

Hole drilling positioning fixture

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

For the more complicated workpiece of structure, use plain clamp to acquire a certain degree of difficulty to its location, especially to 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 hole drilling positioning fixture, 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:

Hole drilling positioning fixture, comprise positioning disk, the end face of positioning disk is with locating ring and the first positioning table, the first positioning table is positioned at locating ring, on the first positioning table with the second positioning table, on the first positioning table, bolt is installed, on positioning disk between locating ring and the first positioning table with alignment pin and material-dropping hole; Briquetting is also installed on positioning disk.

The utility model has the advantage of: according to the concrete structure of workpiece, locating ring and two positioning tables are set on positioning disk, match it is positioned with workpiece respectively, and use briquetting to compress workpiece, material-dropping hole is set on positioning disk, prevents that the waste material that Drilling operation produces from impacting the drilling quality of workpiece simultaneously.

Accompanying drawing explanation

Fig. 1 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, the utility model comprises positioning disk 1, the end face of positioning disk 1 is with locating ring 2 and the first positioning table 4, the first positioning table 4 is positioned at locating ring 2, both form annular groove, described groove coordinates with the protuberance on workpiece, on the first positioning table 4 with the second positioning table 5, both form gradient, step on workpiece is carried out to limited support, on the first positioning table 5, bolt 6 is installed, can be fixed workpiece, on positioning disk 1 between locating ring 2 and the first positioning table 4 with alignment pin 3 and material-dropping hole 8, alignment pin 3 coordinates with the locating hole on workpiece, can limit workpiece rotates, briquetting 9 is also installed on positioning disk 1, can be to Work-sheet pressing by the screw screwing on briquetting 9,

Using method of the present utility model is as follows:
