Abstract
The utility model relates to the technical field of mechanical processing, in particular to a lengthening rod of a boring cutter, which is used for processing a small-diameter deep hole on a large-sized work-piece. The lengthening rod is provided with a rod shaft. The tail end of the rod shaft is fixedly connected with a main shaft of a machine tool by a bolt, a concave hole which is convenient for a cutter handle of the boring cutter to be embedded into the rod shaft is arranged in the top end of the rod shaft, a dual-head bolt used for strengthening the locking force of the boring cutter isarranged at the bottom part of the concave hole on the rod shaft, a clamping block used for preventing the boring cutter from shifting is arranged at one side of the dual-head bolt near the cutter handle, and a countersunk bolt is arranged on the clamping block. The beneficial effects of the lengthening rod are as follows: the lengthening rod meets the processing requirements of the large-sized machine tool for boring the small-diameter deep hole, and enhances the rigidity of the boring cutter by the diameter changing of the main shaft.
Description
Technical field
The utility model relates to the Machining Technology field, especially a kind of boring cutter extension bar that is used for the Machining Small-deep Hole on the large-scale workpiece.
Background technology
At the machine-building manufacture field, usually to carry out deep hole machining, heavy duty machine tools machining large workpiece, junior machine processing miniature workpiece to some workpiece, yet also have some special circumstances for example to need on large-scale workpiece, to process Small-deep Hole, junior machine can't be placed large-scale workpiece, and the main shaft of large machine tools diameter can't be processed too greatly, and in the deep hole processing process, cutter must be grown, but cutter is long more, and its rigidity is poor more, what inconvenience in the process.
The utility model content
The utility model provides a kind of boring cutter extension bar, can't process this technical problem of Small-deep Hole to solve heavy duty machine tools.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of boring cutter extension bar, has the bar axle, the bar shaft tail end is fixedlyed connected with machine tool chief axis by bolt, be provided with in the bar axle top and be convenient to the shrinkage pool that the boring cutter handle of a knife embeds the bar axle, be positioned at shrinkage pool bottom and be provided with and strengthen cutter and tightly lock the stud of power on the bar axle, stud is provided with the clamp that prevents tool offset by handle of a knife one side.
Further, in order to guarantee the fixing and safety of bar axle when rotation clamp, clamp is provided with dormant bolt.
The beneficial effects of the utility model have satisfied the processing request of heavy duty machine tools boring Small-deep Hole, and by the main shaft reducing, have strengthened the rigidity of cutter.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Wherein: 1, bar axle, 2, handle of a knife, 3, stud, 4, clamp, 5, dormant bolt.
The specific embodiment
With preferred embodiment the utility model is described in further detail in conjunction with the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As shown in Figure 1, a kind of boring cutter extension bar, has bar axle 1, bar axle 1 tail end is fixedlyed connected with machine tool chief axis by bolt, be provided with in bar axle 1 top and be convenient to the shrinkage pool that boring cutter handle of a knife 2 embeds the bar axles, be positioned at the shrinkage pool bottom and be provided with and strengthen cutter and tightly lock the stud 3 of power on bar axle 1, stud 3 is provided with the clamp 4 that prevents tool offset by handle of a knife 2 one sides, fixing and the safety of clamp 4 when guaranteeing bar axle 1 rotation, clamp 4 is provided with dormant bolt 5.
During use, boring cutter handle of a knife 2 is filled in bar axle 1 shrinkage pool, use stud 3 then, two rotation direction reaches the self-locking purpose on the contrary, and the fixing and safety of clamp 4 when regulating dormant bolt 5 and guaranteeing 1 rotation of bar axles, at last bar axle 1 is stretched in the machine tool chief axis, and use bolting, this moment can be to the workpiece processing of holing, and machines the back when dismantling, and reverse operating gets final product as stated above.
