Abstract

The utility model relates to a fixture used for drilling an outer round hole. The fixture used for drilling the outer round hole comprises a base, wherein the base is fixedly connected with a rectangular positioning frame; one pair of opposite side walls of the positioning frame is respectively provided with locating pins and bolts; the other pair of opposite side walls of the positioning frame is respectively provided with a U-shaped groove; a positioning plate is respectively arranged in each U-shaped groove. The fixture used for drilling the outer round hole, which is disclosed by the utility model, has the advantages of simple structure, flexibility and convenience in use, simpleness in clamping and high processing precision.

Description

Bore outer circular hole fixture

Technical field

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

Background technology

Workpiece 6 as shown in Figure 2, it has a disc base, now according to specification requirement, need to go out at the Excircle machining of disc base an aperture, 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 brill outer circular hole 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:

Bore outer circular hole fixture, comprise base, be fixed with rectangle posting on base, a pair of two the relative sidewalls of posting are respectively with alignment pin and bolt, posting another on two relative sidewalls respectively with U-shaped groove, in described U-shaped groove, location-plate is housed.

The utility model has the advantage of: according to the concrete structure of workpiece, a rectangle posting is installed on base, by madial wall installation alignment pin and bolt at posting, workpiece is directly located, by location-plate, be pressed on the end face of workpiece simultaneously, make workpiece stressed more even, be conducive to guarantee positioning precision, simple in structure, flexible and convenient to use, clamping efficiency is high, and machining accuracy is high.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Fig. 2 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 depicted in figs. 1 and 2, the utility model comprises base 1, on base 1, be fixed with rectangle posting 2, a pair of two the relative sidewalls of posting 2 are respectively with alignment pin 3 and bolt 4, alignment pin 3 positions it from the disc base of workpiece 6, posting 2 another on two relative sidewalls respectively with U-shaped groove, in described U-shaped groove, location-plate 5 is housed, the parallel sidewalls of location-plate 5 and construction bolt 4, rotating bolt 4 makes it be pressed in location-plate 5, and the quantity of bolt 4 is a plurality of being evenly distributed, can make the stressed even of location-plate 5, the positioning precision of favourable assurance workpiece 6,

Using method of the present utility model is as follows:

The first step, is fixed on base 1 on operating desk;

Second step, coordinates the locating hole on workpiece 6 disc bases with the alignment pin 3 in posting 2;

The 3rd step, is placed in location-plate 5 in described U-shaped groove;

The 4th step, rotating bolt 4, makes it to location-plate 5, compress, and then workpiece 6 is clamped on the sidewall of posting 2;

The 5th step, carries out Drilling operation to the disc base cylindrical of workpiece 6.

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.
