Device for assisting boring machine to process long conical through hole

Abstract

The invention relates to a device for assisting a boring machine to process a long conical through hole. The device comprises a connecting base fixedly connected with a boring machine faceplate, a boring rod fixedly connected with the connecting base, a first bracket and a second bracket mounted on a boring machine stand and supported at the two ends of the boring rod, a driving gear coating at the shaft neck end, close to the boring machine faceplate, of the boring rod and fixedly connected with the boring rod, a duplex gear in clearance fit with the boring rod, a transition gear mounted on the first bracket and synchronously engaged to the driving gear and a first gear of the duplex gear, a guide plate having a certain included angle with the axis of the boring rod and fixed at one side of the boring rod, a lead screw rotationally connected to lead screw bases at the two ends of the guide plate, a cutter holder coating on the lead screw and capable of sliding along the guide plate, a cutter fixed on the cutter holder and outwards extending perpendicular to the guide plate, and a driven gear fixed on the lead screw and engaged to a second gear of the duplex gear, wherein the included angle of the lead screw and the axis of the boring rod is equal to the taper of a long conical hole of a workpiece; and the first gear of the duplex gear is fewer than the driving gear by one tooth.

Description

technical field [0001] The invention relates to a device for assisting a boring machine in machining long tapered through holes. Background technique [0002] Generally, the long tapered through hole of the workpiece can be processed by a lathe, but when the workpiece is too large or the shape of the workpiece is asymmetrical, no matter whether it is a vertical lathe or a horizontal lathe, the long tapered through hole cannot be processed on such a workpiece. . This is because: first, the workpiece itself is bulky or the radius of rotation is too large due to the asymmetry of the workpiece, so that the space for the lathe to accommodate the workpiece is not enough; second, the centrifugal force generated during the rotation of the asymmetric workpiece not only affects the rotation of the workpiece Machining accuracy also brings certain safety hazards. The boring machine generally cannot be used to process the long taper through hole of the workpiece. Contents of the inve...

[0002] Generally, the long tapered through hole of the workpiece can be processed by a lathe, but when the workpiece is too large or the shape of the workpiece is asymmetrical, no matter whether it is a vertical lathe or a horizontal lathe, the long tapered through hole cannot be processed on such a workpiece.

This is because: first, the workpiece itself is bulky or the radius of rotation is too large due to the asymmetry of the workpiece, so that the space for the lathe to accommodate the workpiece is not enough; second, the centrifugal force generated during the rotation of the asymmetric workpiece not only affects the rotation of the workpiece Machining accuracy also brings certain safety hazards

The boring machine is generally not used to process the long taper through hole of the workpiece.
