Description

A kind of efficient broaching equipment

Technical field

The utility model belongs to field of machining, especially a kind of efficient broaching equipment.

Background technology

Bore hole is to forging, and cast out or the further processing of drilling bore hole, bore hole can expand aperture, improves precision, reduces surface roughness.Bore hole can be divided into heavy boring, half right boring and right boring.Large scale reaming processing is needed just can reach required aperture requirement, processing time consuming, complex procedures through repeatedly Boring process.

Utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art part, provides the efficient broaching equipment that a kind of design science is reasonable, structure is simple, stability is high.

The utility model solves its technical problem and takes following technical scheme to realize:

A kind of efficient broaching equipment, comprise tailstock seat, lathe bed, middle die holder, head of a bed seat, master hydraulic bar, tailstock seat is packed in lathe bed one end, head of a bed seat is packed in the lathe bed other end, middle die holder adjustment is arranged on the lathe bed between headstock and tailstock case, described tailstock seat, middle die holder and head of a bed seat are shaped with coaxial centre bore coaxial support workpiece to be processed, described master hydraulic bar is packed in the centre bore also through head of a bed seat on the lathe bed outside head of a bed seat one end, the master hydraulic bar of workpiece side is coaxially installed with cornish bit, master hydraulic bar is coaxial with workpiece, it is characterized in that: cornish bit operative end surface symmetry was shaped with tank and waste material mouth, bite is fixed with in the equal symmetry of waste material mouth center edge portion of the operative end surface of cornish bit, waste material mouth center edge portion wherein outside the bite of side is fixed with an assisted machining cutter.

And the operative end surface of described cornish bit is a coned face.

Advantage of the present utility model and good effect are:

The utility model structure simple, reasonable in design, effective guarantee equipment working (machining) efficiency, and then the axiality and the machining accuracy that ensure processing work, save material, save manpower, remarkable improving production efficiency and quality, effectively promotes single reaming amount.

Accompanying drawing explanation

Fig. 1 is the utility model structural front view;

Fig. 2 is the cornish bit structural representation in the utility model.

Detailed description of the invention

Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.

A kind of efficient broaching equipment, comprise tailstock seat 7, lathe bed 1, middle die holder 5, head of a bed seat 3, master hydraulic bar 2, tailstock seat is packed in lathe bed one end, head of a bed seat is packed in the lathe bed other end, middle die holder adjustment is arranged on the lathe bed between headstock and tailstock case, described tailstock seat, middle die holder and head of a bed seat are shaped with coaxial centre bore and the fixing workpiece 6 to be processed of support, described master hydraulic bar is packed in the centre bore also through head of a bed seat on the lathe bed outside head of a bed seat one end, the master hydraulic bar of workpiece side is coaxially installed with cornish bit 4, master hydraulic bar is coaxial with workpiece.

Innovative point of the present utility model is:

Cornish bit operative end surface as shown in Figure 2, symmetry was shaped with tank and waste material mouth, bite 43 is fixed with in the equal symmetry of waste material mouth center edge portion of the operative end surface 41 of cornish bit, waste material mouth center edge portion wherein outside the bite of side is fixed with an assisted machining cutter 42, these three cutter actings in conjunction, effective increase cutting speed, promotes working (machining) efficiency.

For the ease of feed processing, the operative end surface of this cornish bit is a coned face.

Although disclose embodiment of the present utility model and accompanying drawing for the purpose of illustration, but it will be appreciated by those skilled in the art that: in the spirit and scope not departing from the utility model and claims, various replacement, change and amendment are all possible, therefore, scope of the present utility model is not limited to the content disclosed in embodiment and accompanying drawing.
