Abstract
The utility model relates to a boring rod device assisting a boring machine with large asymmetrical workpiece outer circle machining. The device solves the technical problems that when a lathe is used for machining large asymmetrical workpieces, space of the lathe for accommodating a workpiece is insufficient, centrifugal force generated in the workpiece rotating process affects machining accuracy of the workpiece, and a cutter can not reach the workpiece outer circle when a boring machine machines the workpiece. The boring rod device comprises a cutter handle, a cutter arm, a cutter rod and a cutter body. The cutter handle is fixedly connected with a boring machine main shaft hole, the cutter arm is perpendicular to the cutter handle and fixedly connected with one end, far from the main shaft hole, of the cutter handle, the cutter rod is parallel to the cutter handle and fixedly connected with one end, far from the cutter handle, of the cutter arm, and the cutter body is inward perpendicular to the cutter rod in the radial direction of the boring machine main shaft hole and fixedly connected with one end, far from the cutter arm, of the cutter rod.
Description
Technical field
The utility model relates to the boring bar device of the large-scale asymmetric excircle of workpiece of a kind of auxiliary Boring machine processing.
Background technology
The cylindrical of general workpiece all is to process with lathe, but no matter is vertical lathe or horizontal machine tool, and size and the symmetry of workpiece had requirement.If workpiece size is excessive, then the workbench of lathe is not enough to hold workpiece; If workpiece is asymmetric, then the centrifugal force that produces in turning course of workpiece not only can affect the machining accuracy of workpiece, also can bring potential safety hazard.So large-scale asymmetric workpiece, such as bale panoramic tables because its profile is asymmetric greatly again, can not be processed at lathe.
Summary of the invention
The boring bar device that the purpose of this invention is to provide the large-scale asymmetric excircle of workpiece of a kind of auxiliary Boring machine processing.
Technical scheme of the present invention is: the boring bar device of the large-scale asymmetric excircle of workpiece of a kind of auxiliary Boring machine processing, comprise the handle of a knife that is fixedly connected with the boring spindle hole, perpendicular to handle of a knife and the tool arm that is fixedly connected with away from the main shaft nose end with handle of a knife, the knife bar that is parallel to handle of a knife and is fixedly connected with away from shank end with tool arm is radially inwardly perpendicular to knife bar and the cutter that is fixedly connected with away from the tool arm end with knife bar.
Adopt the technical solution of the utility model, at first because in the process of boring machine, boring bar rotates, and workpiece is motionless, has overcome large-scale asymmetric workpiece because of the impact of the centrifugal force that produces on Workpiece Machining Accuracy.Then because the workbench of boring machine is large more than the workbench of lathe, overcome workpiece because the oversize problem that does not have the space to lay.The setting of last tool arm can be so that cutter reaches the cylindrical of workpiece, and the setting of knife bar can be so that the cutter cylindrical of processing work certain-length vertically.
Description of drawings
The boring bar device elevation cross-sectional view of the auxiliary large-scale asymmetric excircle of workpiece of Boring machine processing of Fig. 1
The specific embodiment
The boring bar device of the large-scale asymmetric excircle of workpiece of a kind of auxiliary Boring machine processing as shown in Figure 1 wraps handle of a knife 1, tool arm 2, knife bar 3, cutter 4 and marks closely screw 5.Handle of a knife 1 is installed in the boring spindle hole, with boring spindle hole interference fit, to introduce the power of boring machine.Tool arm 2 is perpendicular to handle of a knife 1, and its end that is connected with handle of a knife 1 is provided with the through hole with handle of a knife 1 matched in clearance, and the through hole both sides respectively scribble lap welding seam, and tool arm 2 is fixed on the handle of a knife 1.Knife bar 3 is parallel with handle of a knife 1, and the end that tool arm 2 is connected with knife bar 3 also is provided with the through hole with knife bar 3 matched in clearance, and the both sides of this through hole also respectively scribble lap welding seam, and knife bar 3 is fixed on the tool arm 2.Cutter 4 is installed in knife bar 3 away from tool arm 2 ends, and perpendicular to knife bar 3, namely the point of a knife of cutter 4 vertically points to the axis in boring spindle hole along the spindle bore to inwardly.Cutter 4 usefulness holding screws 5 are fixed on the knife bar 3.
