Description

A kind of endoporus machining tool fixture

Technical field

The utility model relates to a kind of frock clamp, is specifically related to the machining tool fixture of a kind of major diameter, long cylindrical shell class inner bore of part.

Background technology

At present in the endoporus processing and manufacturing field of major diameter, long cylindrical shell class part, conventional method, dedicated tool is mainly relied on to process.Its process principle is:

Part one end is clamped on the chuck of lathe main shaft end, and another end-rack is on centre frame; Boring cutter bar clamping is on tail planker.Add and drive part to rotate by main shaft man-hour, tail planker carry its tools completes the processing of part do axially-movable.

Its main Problems existing is: part draw ratio is large, the unsettled distance of knife bar, causes arbor stiffness poor, and easily occur cutter relieving and cutter phenomenon of shaking, element precision not easily ensures.

Utility model content

The technical problems to be solved in the utility model is to provide a kind of endoporus machining tool fixture, solves the cutter relieving and cutter phenomenon of shaking that easily occur in processing parts process, ensures the machining accuracy of part.

For achieving the above object, the technical solution of the utility model is as follows:

A kind of endoporus machining tool fixture, comprising:

One handle of a knife, the handle of a knife connector be connected with handle of a knife, described handle of a knife is provided with the thread segment for connecting, handle of a knife is connected with handle of a knife connector by thread segment,

Described handle of a knife end is symmetrical arranged gathering sill, and place guide pad in described gathering sill, boring cutter runs through in the locating slot being arranged at and handle of a knife is offered.

Preferably, described boring cutter adopts floating structure, and boring cutter external diameter is the diameter of bore of part requirements, and boring cutter carries out axial restraint.

Preferably, described guide pad is wooden guide pad.

By technique scheme, the beneficial effects of the utility model are:

Pass through the utility model, solve in major diameter, long cylindrical shell class part process due to the unsettled distance of knife bar, easily cause arbor stiffness poor, there is cutter relieving and shake cutter and element precision not easily ensure problem, ensure that the quality of part, there is structure simple, accurate positioning, easy to operate feature.

Accompanying drawing explanation

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

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

Fig. 2 is generalized section of the present utility model.

Fig. 3 is another generalized section of the present utility model.

Detailed description of the invention

The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.

With reference to shown in Fig. 1, Fig. 2 and Fig. 3, a kind of endoporus machining tool fixture, comprising:

One handle of a knife 1, the handle of a knife connector 4 be connected with handle of a knife 1, described handle of a knife 1 is provided with the thread segment for connecting, handle of a knife 1 is connected with handle of a knife connector 4 by thread segment.

Described handle of a knife 1 end symmetric is provided with gathering sill 5, and place guide pad 3 in described gathering sill 5, boring cutter 2 runs through in the locating slot being arranged at and handle of a knife 1 is offered.

Described boring cutter 2 adopts floating structure, and boring cutter 2 external diameter is the diameter of bore of part requirements, and boring cutter 2 only carries out axial restraint, and radial direction is not fixed.

Described guide pad 3 is a pine, can make knife bar maintaining rigidness adding to be guided by the guide pad 3 on cutter head and supported man-hour, there will not be cutter relieving and cutter phenomenon of shaking.

Operation principle of the present utility model is:

Before bore hole, on part, first process a bullport, the diameter of bullport with want bore diameter consistent.After bullport machines, load onto this utility model, by the motor that lathe tail planker is equipped with, drive handle of a knife 1 to make axial feed, now guide pad 3 enters bullport inner position, and effectively supports boring cutter 2, ensures the balance of cutting force;

Along with the continuous increase of working depth, the endoporus of formation can make guide pad continue to support knife bar, ensures stability and the centering of knife bar, finally completes the processing of part.

More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
