Abstract
The invention relates to a high-precision hole-milling positioning tool which comprises a positioning disc. The center of the positioning disc is provided with an annular positioning table. The center of the positioning table is provided with a cylinder. Bolts are mounted symmetrically about the axis, parallel to the positioning table, of the disc. The bolts penetrate through kidney-shaped holes of pressing blocks. Ejector rods are fixed between the bottom surfaces of the pressing blocks and the disc. The high-precision hole-milling positioning tool is simple in structure, flexible and convenient to use and high in clamping efficiency, and machining precision is easy to guarantee.
Description
Technical field
The present invention relates to technical field of tooling clamps, relate in particular to for workpiece being carried out to the positioning fixture of hole milling processing.
Background technology
Workpiece 1 as shown in Figure 1, need process several locating holes in its top end according to specification requirement, but because it is ring-type up and down, exists and be positioned at difficulty, is difficult for using common frock clamp.
Summary of the invention
The present invention is directed to above-mentioned shortcoming of the prior art, a kind of high accuracy hole milling positioning tool is provided, it is simple in structure, flexible and convenient to use, and clamping is simple, and machining accuracy is high.
The technical solution adopted in the present invention is as follows:
High accuracy hole milling positioning tool, comprises positioning disc, and disk central authorities are with ring-type positioning table, positioning table center is cylinder, on disk, the axis of positioned parallel platform is symmetrically installed with bolt, and bolt is through in the mounting hole of briquetting, between briquetting bottom surface and disk, is fixed with push rod.
The invention has the advantages that: the positioning table and the cylinder that match with workpiece polycrystalline substance are set on positioning disc and from workpiece bottom, it are carried out to effective location, bolt and briquetting are set simultaneously to be compressed it from the upper surface of workpiece, simple in structure, flexible and convenient to use, clamping is simple, and machining accuracy is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of workpiece.
Fig. 2 is structural representation of the present invention.
Fig. 3 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 shown in Figure 1 to Figure 3, the present invention includes positioning disc 2, disk 2 central authorities are with ring-type positioning table 3, positioning table 3 is for the whole workpiece 1 of the bottom support from workpiece 1, positioning table 3 centers are cylinder 4, cylinder 4 coordinates location with the centre bore on workpiece 1 chassis, on disk 2, the axis of positioned parallel platform 3 is symmetrically installed with bolt 5, bolt 5 is through in the mounting hole of briquetting 6, facilitate the upper-lower position of briquetting 6 on bolt 5 to regulate, between briquetting 6 bottom surfaces and disk 2, be fixed with push rod 7, be used for supporting briquetting 6, make briquetting 6 keep horizontal equilibrium, concora crush is on the upper surface of workpiece 1,
Using method of the present invention is as follows:
The first step, positioning disc 2 is fixed on operating desk;
Second step, by being placed on positioning table 3 of workpiece 1 chassis, makes the centre bore on workpiece 1 chassis coordinate with cylinder 4;
The 3rd step, upwards regulates along bolt 5 upper surface that is pressed on workpiece 1 briquetting 6, and push rod 7 upwards withstands briquetting 6 from briquetting 6 bottoms simultaneously;
The 4th step, screws bolt 5, and it is exerted pressure to briquetting 6, guarantees that the location of workpiece 1 firmly can not rotate;
The 5th step, carries out hole milling processing to the upper surface of workpiece 1.
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.
