Abstract

The invention relates to a high-precision drilling clamp which comprises a positioning plate, wherein a positioning pin, a center positioning hole and a pair of bolts are arranged on and formed in the positioning plate, the pair of bolts is symmetrical with the axis of the positioning hole serving as the axis, pressing blocks are arranged on the bolts, and the end face of the positioning plate is provided with steps. The high-precision drilling clamp is simple in structure, convenient and flexible to use, easy to clamp and high in machining precision.

Description

High-precision borehole fixture
Technical field
The present invention relates to technical field of tooling clamps, relate in particular to the fixture for location that workpiece is holed.
Background technology
Field of machining, often need to hole to various workpiece, the processing such as turning, for a common workpiece, it being carried out to simple positioning instant can, but for the workpiece of complicated structure, simultaneously higher to requirement on machining accuracy, must use special-purpose positioning tool to process.
Summary of the invention
The present invention is directed to above-mentioned shortcoming of the prior art, a kind of high-precision borehole fixture is provided, it is simple in structure, flexible and convenient to use, and clamping efficiency is high, and machining accuracy is high.
The technical solution adopted in the present invention is as follows:
High-precision borehole fixture, comprises positioning disk, and on positioning disk, with alignment pin, center positioning hole and pair of bolts, pair of bolts is symmetrical about the axis of locating hole, and briquetting is installed on bolt, and the end face of positioning disk is with step.
The invention has the advantages that: according to the structure of workpiece, to the centre bore that workpiece cylindrical section is positioned is set on positioning disk, whether construction bolt and briquetting compress workpiece simultaneously, alignment pin is installed on positioning disk its workpiece is accurately located, accurate to the location of workpiece for detecting, step is set on positioning disk, whether level is whether provable workpiece location is accurate, simple in structure, flexible and convenient to use to detect step, clamping efficiency is high, and machining accuracy is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is use state diagram of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As depicted in figs. 1 and 2, the present invention includes positioning disk 1, on positioning disk 1 with alignment pin 2, center positioning hole 3 and pair of bolts 4, alignment pin 2 coordinates with the locating hole on workpiece 7 chassis, can limit the rotation of workpiece 7, center positioning hole 3 coordinates with the cylindrical section on workpiece 7, pair of bolts 4 is symmetrical about the axis of locating hole 3, briquetting 5 is installed on bolt 4, briquetting 5 acts on the end face of workpiece 7, can guarantee effect force rate compared with uniform balance, the end face of positioning disk 1 is with step 6, after workpiece 7 is had good positioning, whether the plane that detects step 6 level, whether accurately can judge the location of workpiece 7, add man-hour, positioning disk 1 is mounted on operating desk, make workpiece 7 need the position level of boring, workpiece 7 is carried out to Drilling operation,
Using method of the present invention is as follows:
The first step is installed workpiece 7 on positioning disk 1, make each position on workpiece 7 respectively with center positioning hole 3, alignment pin 2 coordinates;
Second step, adjusting bolt 4, is pressed on the end face of workpiece 7 briquetting 5;
The 3rd step, whether step on detection and location dish 16 level, judges that whether the location of workpiece 7 is accurate;
The 4th step, is fixed on positioning disk 1 on operating desk, and workpiece 7 is carried out to Drilling operation.
More than describing is explanation of the invention, is not the restriction to invention, and limited range of the present invention, referring to claim, within protection scope of the present invention, can be done any type of modification.
