Abstract

The utility model relates to a high-precision hole milling locating tool which comprises a locating round disc. An annular locating table is arranged in the center of the round disc, a cylinder is arranged in the center of the locating table, bolts are symmetrically arranged on the round disc and are parallel to the axis of the locating table, the bolts penetrate through kidney-shaped holes of pressing blocks, and ejector rods are fixed between the bottom faces of the pressing blocks and the round disc. The high-precision hole milling locating tool is simple in structure, flexible and convenient to use and high in assembling efficiency, and processing precision is easy to guarantee.

Description

High accuracy hole milling positioning tool

Technical field

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

Background technology

Workpiece 1 as shown in Figure 1, need process several locating holes in its top end according to technical requirement, but because it is ring-type up and down, exists and be positioned at difficulty, is difficult for using common frock clamp.

Utility model content

The utility model, for above-mentioned shortcoming of the prior art, provides a kind of high accuracy hole milling positioning tool, and it is simple in structure, flexible and convenient to use, and clamping is simple, and machining accuracy is high.

The technical scheme that the utility model adopts 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 utility model has the advantage of: 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 utility model.

Fig. 3 is use state diagram 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 3, the utility model comprises 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 utility model 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 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.
