Abstract

The utility model relates to a self-control machining hole boring cutter bar, which comprises a pathlet, a cutter bar and a blade, wherein the interior of the cutter bar is provided with a blade slot which corresponds to the blade; the cutter bar is provided with a bolt used for controlling the extension elongation of the blade; and the blade slot penetrates the whole cutter bar at a certain angle. According to the self-control machining hole boring cutter bar, the diameter of a processing hole can be accurate through regulating the extension elongation of the blade, and the use efficiency of a tool is increased.

Description

Self-control machined bore hole knife bar

Technical field

The utility model relates to a kind of self-control machined bore hole knife bar.

Background technology

Machined bore hole knife bar be machining hole than practical tool, general drill bit punching is fixed, and for the aperture different requirement, can only change different knife bars.

The utility model content

The utility model provides a kind of self-control machined bore hole knife bar of new structure.

The major technique of the utility model thes contents are as follows:

A kind of self-control machined bore hole knife bar comprises path, knife bar, blade, is provided with and the corresponding insert groove of blade in the said knife bar, and said knife bar is provided for controlling the bolt of blade extension elongation.

Above-mentioned insert groove tilts to run through whole knife bar at an angle.

By technique scheme, the utility model has advantage at least: the utility model can increase the service efficiency of instrument through regulating the diameter of the accurate machining hole of length that blade stretches out.

The specific embodiment of the utility model is provided by following examples and accompanying drawing thereof in detail.

Description of drawings

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

Fig. 2 is the sketch map of knife bar in the utility model;

Fig. 3 is the sketch map of blade in the utility model.

The specific embodiment

For further setting forth the utility model is to reach technological means and the effect that predetermined utility model purpose is taked; Below in conjunction with accompanying drawing and preferred embodiment; To its specific embodiment, structure, characteristic and the effect thereof that proposes according to the utility model, specify as after.

Like Fig. 1, Fig. 2, shown in Figure 3, a kind of self-control machined bore hole knife bar comprises path 1, knife bar 2, blade 5, is provided with and blade 5 corresponding insert grooves 4 in the said knife bar 2, and said knife bar 2 is provided for controlling the bolt 3 of blade 5 extension elongations.

Insert groove 4 tilts to run through whole knife bar 2 at an angle.

The path 1 of knife bar 2 is packed in the rack sleeve of milling machine, and the extension elongation of regulating blades 5 with the bolt 3 of knife bar 2 is through the high speed rotation smear metal of main shaft.

The above; It only is the preferred embodiment of the utility model; Not being that the utility model is done any pro forma restriction, though the utility model with the preferred embodiment exposure as above, yet is not in order to limit the utility model; Anyly be familiar with the professional and technical personnel; In not breaking away from the utility model technical scheme scope, make a little change or be modified to the equivalent embodiment of equivalent variations when the technology contents of above-mentioned announcement capable of using, be the content that does not break away from the utility model technical scheme in every case;, all still belong in the scope of the utility model technical scheme any simple modification, equivalent variations and modification that above embodiment did according to the technical spirit of the utility model.
