Description

A kind of scalable lengthening boring cutter

Technical field

The utility model relates to field of machining, and in particular to a kind of scalable lengthening boring cutter.

Background technique

In the hole machined of machine-building, Boring can be carried out with boring cutter, in process, workpiece surface is to boring cutter Reaction force be transferred to boring cutter bar after, boring cutter bar can be made to generate radial vibration.

It is smaller that standard cutter system in the market generally processes diameter, and can not adjust on a large scale, in some particular fields It closes accessible processing space range and is not able to satisfy actual processing needs, existing cutter low efficiency and has more when processing big plane Secondary feed not can guarantee flatness, can not process macropore.

Utility model content

Problem to be solved in the utility model is that existing boring cutter low efficiency and has repeatedly to walk when processing big plane Knife not can guarantee flatness, can not process macropore.

The utility model, which adopts the following technical solutions, solves above-mentioned technical problem:

A kind of scalable lengthening boring cutter, including knife handle, knife rest, knife bar, cutter, described knife handle one end are connect with knife rest, institute Knife rest is stated equipped with the cavity vertical with knife handle axis direction, the knife bar is slidably connected through the cavity with knife rest, described Knife rest is equipped with the locating piece of fixed knife bar, and the end of the knife bar is equipped with cutter.

Preferably, the knife rest side wall is equipped with opening along cavity axis direction, and the opening is equipped with fixed block.

Preferably, the locating piece is the first bolt.

Preferably, the knife rest is equipped with threaded hole, and first bolt passes through the fixed knife bar of the threaded hole.

Preferably, the both ends of the knife bar are equipped with cutter.

Preferably, the cutter is fixedly connected by the second bolt with knife bar.

Preferably, the knife bar is scalable knife bar.

Preferably, the knife handle, knife bar are in the form of a column.

Preferably, the knife handle surface sides are equipped with groove, and the Cutting tool installation manner is on groove.

The utility model has the beneficial effects that:

(1) it is slided in cavity by knife bar, keeps knife bar flexible relative to knife rest, so as to process the hole of different-diameter Diameter can once complete big plane machining, and knife bar length is adjustable, extends its range of work；

(2) knife bar both ends are equipped with cutter, and working efficiency can be improved, and are conducive to improve product surface quality.

Specific embodiment

The utility model is described in further details below with reference to Figure of description and embodiment.

Embodiment 1

As shown in Figure 1 and shown in Fig. 2, a kind of scalable lengthening boring cutter, including knife handle 1, knife rest 2, knife bar 3, cutter 4；

1 lower end of knife handle is fixedly connected with knife rest 2, and wherein knife handle 1 is in the form of a column, if be able to satisfy boring cutter work when knife handle 1 with Machine tool chief axis connection；Knife rest 2 is equipped with the cavity vertical with 1 axis direction of knife handle, and knife bar 3 runs through the cavity and knife rest 2 are slidably connected；By sliding of the knife bar 3 in cavity, knife bar 3 may be implemented relative to the flexible of knife rest 2, knife rest 2 can be improved Cutter overall stiffness.

Knife rest 2 is equipped with threaded hole, is equipped with the first bolt 21 in threaded hole hole, by rotating the first bolt 21, plays solid The effect of stationary knife bar 3；Wherein the position of the first bolt 21 and number can be arranged according to actual needs, as long as being able to achieve fixed knife bar 3, the number of the first bolt 21 is 4 in the present embodiment.

2 side wall of knife rest is equipped with opening along cavity axis direction, and the size of opening can be arranged according to actual needs, the opening Place is equipped with fixed block 22, and assistance knife bar 3 is kept fixed and level, and wherein the number of fixed block 22 can be arranged according to actual needs, The number of fixed block 22 is 2 in the present embodiment.

The one or both ends of knife bar 3 are equipped with cutter 4, and cutter 4 is fixed on 3 end of knife bar by the second bolt 31, when in knife When the both ends of bar 3 are equipped with cutter 4, working efficiency can be improved, and be conducive to improve product surface quality, the knife bar 3 is in column Shape, 3 side of knife bar is equipped with groove, the length of the groove and the equal length of knife bar 3 in the present embodiment, and the cutter 4 is installed On groove, wherein cutter 4 is the prior art, is processed as long as being able to achieve to product.

Embodiment 2

The present embodiment difference from example 1 is that: knife bar 3 be scalable knife bar (not shown), stretch mode For the prior art, the telescopic bar or other stretch modes of trolley case can be used, realizes adjustably adjusting for knife bar.

The principles of the present invention: when work, 1 upper end of knife handle is connect with machine tool chief axis, for the different ranges of work, is adjusted After saving the length that knife bar 3 adjusts knife bar 3 relative to the flexible of knife rest 2 or by itself telescopic principle, pass through the first spiral shell Bolt 21 fixes knife bar 3, to process to product.

Above are merely preferred embodiments of the utility model, the protection scope of the utility model is not limited merely to above-mentioned Embodiment, it is within the protection scope of the present utility model with various process programs of the utility model design without substantial differences.
