Description

A kind of cylindric workpiece tangential hole drilling tool

Technical field

The utility model belongs to the technical field of mechanical processing technique equipment, relates to the structure of boring grab.More particularly, the utility model relates to a kind of cylindric workpiece tangential hole drilling tool.

Background technology

In the processing of machine components, often need on the workpiece of cylindrical or tubular, process tangential hole.General tangential hole refers to that its axis is vertical and non-intersect with the axis of whole workpiece.

In the Drilling operation of tangential hole, due to hole on arc surface and hole be set for the eccentric, make drill bit monolateral stressed, drill bit, except being subject to axial force, also will be subject to very large unbalanced radial load, causes that drill bit slides, skew.Therefore, the boring difficulty of carrying out eccentric orfice on arc surface is very large, sometimes cannot process.So this Drilling operation technique is difficult to realize.

Utility model content

The utility model provides a kind of cylindric workpiece tangential hole drilling tool, its objective is the tangential hole Drilling operation of realizing on cylindric workpiece.

To achieve these goals, the technical scheme that the utility model is taked is:

The cylindric workpiece tangential hole drilling tool that the utility model provides, the axis of described tangential hole is vertical and non-intersect with the axis of workpiece, described drilling tool is provided with drill bushing, described drilling tool is provided with lower locating piece and upper locating piece, and described lower sprocket bit and upper locating piece are respectively equipped with the semi-cylindrical coordinating with described excircle of workpiece cylinder.

Under the Drilling operation state of described tangential hole, described workpiece is placed in the circular hole of lower locating piece and two semi-cylindricals formations of upper locating piece, and clamped; And the apparent surface of lower locating piece and upper locating piece has certain interval.

At described lower locating piece, be fixed with limiting plate; Under the Drilling operation state of described tangential hole, the end face of described workpiece contacts with described limiting plate.

Described cylindric workpiece is cylindrical workpiece; Or be the workpiece of tubular; Or be the workpiece of multidiameter.

Compare with bore process on the arc surface of prior art, the utility model adopts technique scheme, has solved the technique difficult problems such as the monolateral stressed and workpiece of drill bit is fixing, and borehole accuracy is higher; Can realize arc surface boring of the same type, be applicable to the manufacturing of multiple product of the same type; Consumable material is few, the cost that saves material, the quality of raising product; Be convenient to maintenance, practicality is high.

Accompanying drawing explanation

Below the expressed content of each width accompanying drawing of this description and the mark in figure are briefly described:

Fig. 1 is the structural representation of processing work in the utility model;

Fig. 2 is the explosive view of the utility model structure;

Fig. 3 is the structural representation of machining state of the present utility model.

In figure, be labeled as:

1, lower locating piece, 2, upper locating piece, 3, limiting plate, 4, drill bushing, 5, workpiece, 6, base plate, 7, tangential hole.

The specific embodiment

Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present utility model is described in further detail, to help those skilled in the art to have more complete, accurate and deep understanding to inventive concept of the present utility model, technical scheme.

As shown in Figure 1, be the workpiece 5 of tubular, be provided with tangential hole 7.The axis of described tangential hole 7 is vertical and non-intersect with the axis of workpiece 5.

Structure of the present utility model shown in Fig. 2, is a kind of cylindric workpiece tangential hole drilling tool, and described drilling tool is provided with drill bushing 4.Described drill bushing 4 plays the effect into drill bit guiding and increase rigidity.This drilling tool is used in the Drilling operation of the eccentric orfice on arc surface.

In order to solve the problem of prior art existence and to overcome its defect, realize the goal of the invention of the tangential hole Drilling operation on cylindric workpiece, the technical scheme that the utility model is taked is:

As shown in Figure 2, the cylindric workpiece tangential hole drilling tool that the utility model provides is provided with lower locating piece 1 and upper locating piece 2, and described lower locating piece 1 and upper locating piece 2 are respectively equipped with the semi-cylindrical coordinating with described workpiece 5 external cylindrical surfaces.

Lower locating piece 1 is fixed on base plate 6.

Above-mentioned drilling tool has solved the problem of boring eccentric orfice on arc surface, can realize the processing and manufacturing of product of the same type.Compare with drilling technique on existing arc surface, the precision of drilling tool that the utility model provides boring is higher, has solved the technique difficult problems such as the monolateral stressed and workpiece of drill bit is fixing.

Under the Drilling operation state of described tangential hole 7, described workpiece 5 is placed in the circular hole of lower locating piece 1 and 2 two semi-cylindricals formations of upper locating piece, and clamped; And the apparent surface of lower locating piece 1 and upper locating piece 2 has certain interval.

Adopt said structure technical scheme, can realize Workpiece clamping, while guaranteeing boring, workpiece can not become flexible.

At described lower locating piece 1, be fixed with limiting plate 3; Under the Drilling operation state of described tangential hole 7, the end face of described workpiece 5 contacts with described limiting plate 3.

By the workpiece of upper and lower locating piece, drill bushing, base plate and limiting plate location and fastening arc-shaped surface, then on drilling machine, hole.

Described cylindric workpiece is cylindrical workpiece; Or be the workpiece of tubular; Or be the workpiece of multidiameter.

Structure of the present utility model can be applied to the processing of the tangential hole on the cylindrical outer surface of above-mentioned multiple similar type.Its advantage is:

1, can realize arc surface boring of the same type, be applicable to the manufacturing of multiple product of the same type.
