Abstract

The invention discloses a processing technology of two intersected cylinders, and the method comprises the following steps: (1) blanking a round steel blank; (2) utilizing a chuck to clamp the blank, and turning one end of the blank; (3) turning the other end of the blank; (4) reaming other two end surfaces respectively and drilling a central hole; (5) propping the central holes at the two ends and turning the outer circle of a small cylinder; (6) removing the redundant part of the small cylinder; (7) milling each plane; and (8) drilling each hole and tapping. The processing technology disclosed by the invention has the beneficial effects that two intersected cylinders can be simply and reliably processed on a general machine tool, the efficiency is high, and the cost is low.

Description

The processing technology of two intersected cylinders

Technical field

The present invention relates to adding of machine components, especially the processing technology of two intersected cylinders.

Background technology

Some part is made up of two intersected cylinders in machine-building, and promptly the axis of two cylinders intersects in same plane, like the flexible knife bar of boring tool.The processing of this part is difficulty relatively, and the instrument of generally wanting design special.

Summary of the invention

The present invention has worked out a kind of processing technology of two intersected cylinders, on engine lathe, just can process the cylindrical of two intersected cylinders without specific purpose tool.

The technical solution adopted for the present invention to solve the technical problems is: utilize the centre bore that is processed on the part blank to go out to process the cylindrical of main cylinder.

The invention has the beneficial effects as follows, on general lathe, can process two cylinders of two intersected cylinders, efficient, expensive low simple and reliablely.

The processing technology of two intersected cylinders is (1), the blanking of round steel blank; (2), clamp Che Yiduan with chuck; (3), the car other end; (4), distinguish ream end flat drill centers in addition; (5), head part two ends centre bore car small column cylindrical; (6), remove the redundance of small column; (7), mill each plane; (8), bore each hole and tapping.

The specific embodiment

The flexible knife bar that is used for the boring tool of 120～130 millimeters endoporus grooves of car diameter is exactly the part that two cylinders intersect.Technical process is following:

(1), the blank blanking of flexible knife bar.By the flexible big end of knife bar, just the big column diameter adds that the surplus of processing excircles selects the round steel of corresponding size.Blank length is by flexible knife bar small end, and just the physical length of small column axis direction adds because need the length of drill centers part.Sawed-off with common sawing machine.

(2), on lathe, clamp the left end of blank with chuck, behind the right-hand member drill centers of blank, withstand with top, car right-hand member cylindrical, the length of institute's turning is as the criterion with the needs that can satisfy the clamping of next procedure chuck;

(3), on lathe, live in the half-finished right-hand member of flexible knife bar of procedure with gripper chuck; The right-hand member of just original blank; Behind half-finished left end drill centers of flexible knife bar last process, withstand with top, car left end cylindrical, consistent with the right-hand member excircle dimension of car;

(4), flexible knife bar semi-finished product end flat, the drill centers of difference ream last process.Being placed on the flexible knife bar semi-finished product of last process at the intersection point of the big end cylinder axis of flexible knife bar and small end cylinder axis on the flexible knife bar semi-finished product that make last process on the disk workbench overlaps with pivot on the disk workbench.At knife bar small end cylinder axis position spot facing, the drill centers on half-finished end flat of flexible knife bar last process respectively of stretching.Generally on horizontal milling machine, process.Earlier according to the intersecting point dimension L of flexible knife bar large end face to flexible big end cylinder axis of knife bar and small end cylinder axis; The half-finished axis of flexible knife bar of the last process that is installed in workbench is overlapped with the pivot of milling machine spindle; Rotate by the angle of flexible big end cylinder axis of knife bar and small end cylinder axis again, make that the small end cylinder axis overlaps with the pivot of milling machine spindle on the flexible knife bar semi-finished product of last process.Flexible knife bar semi-finished product end flat, the drill centers of difference ream last process.

(5), withstand the centre bore at the flexible knife bar semi-finished product two ends of last process, the clip of stirring the flexible knife bar semi-finished product rotation of last process is contained in the half-finished big end of flexible knife bar of last process, at the lathe flexible knife bar small column cylindrical of getting on the bus.

6), remove the redundance of the small column on the flexible knife bar semi-finished product of last process;

(7), mill half-finished each plane of flexible knife bar of last process;

(8), bore half-finished each hole of flexible knife bar of last process and attack respective threads.

Claims

1. the processing technology of the flexible knife bar of a boring tool is characterized in that:

(1), the blank blanking of flexible knife bar;

(2), on lathe, clamp the left end of the blank of flexible knife bar, car right-hand member cylindrical with chuck;

(3), on lathe, live in the half-finished right-hand member car of the flexible knife bar left end cylindrical of procedure with gripper chuck, consistent with the right-hand member excircle dimension of car;

(4), the half-finished end flat of flexible knife bar, the drill centers of difference ream last process; Be placed on the flexible knife bar semi-finished product of last process on the disk workbench; The intersection point of the big end cylinder axis of flexible knife bar and small end cylinder axis on the flexible knife bar semi-finished product of last process is overlapped, by flexible knife bar small end cylinder axis position spot facing, drill centers at the half-finished two ends of flexible knife bar of last process respectively with pivot on the disk workbench;

(5), withstand the centre bore at the half-finished two ends of flexible knife bar of last process, at the get on the bus small column cylindrical of flexible knife bar of lathe;

(6), remove the redundance of the small column on the flexible knife bar semi-finished product of last process;

(7), mill each plane on the flexible knife bar semi-finished product of last process;

(8), bore each hole on the flexible knife bar semi-finished product of last process and attack respective threads.
