Abstract
A double-headed boring cutter bar comprises a cutter handle and an extension bar, wherein a transmission groove is formed in the inclined surface of the cutter handle; an extension bar mounting hole is formed in the working surface of the cutter handle; the extension bar is sleeved in the mounting hole; and two cutter handle mounting holes are formed on the extension bar. The double-headed boring cutter bar has a simple structure and high work stability. Two different boring cutters can be arranged on the boring cutter bar at the same time, so that the double-headed boring cutter bar is very suitable for processing special-shape holes. During operation, the end part of the extension bar is inserted into a boring bar supporting hole, so that vibration caused by the overlong boring cutter bar can be avoided. The double-headed boring cutter bar reduces operation of assembling, disassembling and calibrating in one cutter exchanging process, simplifies the processing procedures, improves the work efficiency, saves cost for enterprises and has a good economic benefit.
Description
Technical field
The present invention relates to a kind of processing equipment, especially relate to a kind of double end boring cutter bar.
Background technology
In the process of machining, usually need to be equipped with for boring machine the boring cutter bar of some, to adapt to the demand of processing different pore size, particularly needed knife bar specification can be more when producing peculiar part, boring irregularly-shaped hole, so just increase production cost, all increased expense such as the manufacturing of knife bar, preservation, maintenance etc.And the frequent boring cutter bar, the workload of loading and unloading cutter, correction main shaft is also quite large.
Summary of the invention
The object of the invention provides a kind of double end boring cutter bar, and the specification that existing boring cutter bar exists is single, the tool changing workload large, production cost high-technology problem to solve.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind of double end boring cutter bar, comprise handle of a knife, extension rod, described handle of a knife is provided with driving groove on the inclined-plane, be provided with the extension rod installing hole on the handle of a knife working face, described extension rod is sleeved in the installing hole, is provided with two handle of a knife installing holes on the extension rod.
As preferably, the described extension rod face of cylinder is provided with the handle of a knife fixed screw holes.
As preferably, described handle of a knife is provided with the extension rod fixed screw holes on the face of cylinder.
As preferably, described extension rod axially is ladder-type structure.
As preferably, described handle of a knife fixed bolt hole is perpendicular to the handle of a knife installing hole.
The present invention has simple in structure, good operating stability, can at boring cutter bar two different boring cutters be installed simultaneously, be fit to very much processing profiled hole, during work the extension rod end be inserted in the boring bar supported hole, can avoid the vibration that causes because boring cutter bar is long, and the double end boring cutter bar reduced the work such as the loading and unloading, calibration in the exchanging knives process, simplified manufacturing procedure, improved production efficiency, can for enterprise saves cost, have good economic benefit.
Description of drawings
Below in conjunction with the drawings and specific embodiments, technical scheme of the present invention is described in further detail.
Fig. 1 is structural representation of the present invention;
Fig. 2 is top view of the present invention.
The specific embodiment
Fig. 1 is structural representation of the present invention, and Fig. 2 is top view of the present invention.In conjunction with Fig. 1,2 as can be known, this double end boring cutter bar comprises handle of a knife 1, extension rod 2 etc., is provided with driving groove 3 on described handle of a knife 1 inclined-plane, is provided with extension rod installing hole 4 on handle of a knife 1 working face, is provided with extension rod fixed screw holes 5 on handle of a knife 1 face of cylinder; Described extension rod 2 is ladder-type structure axially, is provided with two handle of a knife installing holes 6 on the extension rod 2, and extension rod 2 faces of cylinder are provided with handle of a knife fixed screw holes 7, and handle of a knife fixed bolt hole 7 is perpendicular to handle of a knife installing hole 6.
When this double end boring cutter bar uses, the driving groove 3 on handle of a knife 1 inclined-plane is aimed at main shaft, locking knife handle 1.Extension rod 2 is inserted in the extension rod installing hole 4, extension rod 2 other ends insert in the boring bar supported hole 8 of workbench, in extension rod fixed screw holes 5, fixed screw is installed, locking extension rod 2, boring cutter is installed on the extension rod 2 subsequently, in extension rod side handle of a knife fixed screw holes 7 fixed screw is installed, the locking boring cutter can be processed.
