Abstract
The invention relates to a boring cutter. The boring cutter comprises a cutter bar and a cutter body. A conical body is arranged at the left end of the cutter bar and is matched with another conical body of a main shaft hole of a boring machine, and an inner threaded hole is formed in the axis of the conical body. The conical body is connected with a connecting rod of a main shaft of the boring machine through a metric thread, so that the tensioning effect is achieved. Shoulder shafts are arranged at the right end of the cutter bar, a left radial cutter body fixing hole and a right radial cutter body fixing hole are formed in the right ends of the shoulder shafts respectively, and a left boring cutter and a right boring cutter are fixed in the left cutter body fixing hole and the right cutter body fixing hole respectively. The boring cutter is simple in structure, and can carry out hole diameter machining beyond the machining range of equipment.
Description
Technical field
The present invention relates to a kind of cutter, the boring cutter that particularly a kind of milling machine bore hole is used.
Background technology
Motor base is that the aperture of carrying out again two holes after welding completes processes, in order to guarantee the depth of parallelism of its aperture and base end face and the axiality between two holes, must first pass through scribing by bench worker, and carrying out boring processing after prebored hole, because the centre-to-centre spacing between two holes has exceeded the scope of device travel processing, to machined, bring very large difficulty.
Traditional processing method is to machine two apertures are disposable, and the workpiece axiality processing is like this good, and precision is high.But because the centre-to-centre spacing between two holes has exceeded the range of work of equipment, existing equipment cannot complete processing tasks.
Summary of the invention
In order to overcome the shortcoming of prior art, the invention provides a kind of boring cutter, it is simple in structure, can realize and processing exceeding equipment range of work aperture in addition.
The present invention solves the technical scheme that its technical problem takes: it comprises knife bar and cutter, the left end of knife bar is cone, cone coordinates with the cone in boring spindle hole, there is internal thread hole in the axle center of cone, be connected by metric thread with the connecting rod of boring spindle, play tensioning function, the right-hand member of knife bar is shoulder axle, shoulder axle, right-hand member have respectively left and right cutter fixing hole radially, left and right cutter fixing hole, interior fixing left and right boring cutter respectively.
The present invention has following advantages: 1, can realize and processing exceeding equipment range of work aperture in addition, guarantee after processing that the axiality scope between two apertures is in 0.05mm; 2, working (machining) efficiency is high, and the range of work is wide; 3, scrap build investment is little, and after transformation, does not affect the processing characteristics of former milling machine.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this present invention is further illustrated.
Fig. 1 is cutaway view of the present invention.
The specific embodiment
As shown in Figure 1, the present invention includes knife bar and cutter, the left end of knife bar is cone 2, cone 2 coordinates with the cone in boring spindle hole, and there is internal thread hole 1 in the axle center of cone 2, is connected by metric thread with the connecting rod of boring spindle, play tensioning function, the right-hand member of knife bar is shoulder axle 4,6, and the right-hand member of shoulder axle 4,6 has respectively left and right cutter fixing hole 9,8 radially, the interior fixing left and right boring cutter 5,7 respectively of left and right cutter fixing hole 9,8.
Described cone 2 has the groove 3 larger than cone 2 outside diameters with the intersection of shoulder axle 4,6, the groove 3 formation rigid connection that matches with the projection of boring machine.
Claims (2)
1. a boring cutter, comprise knife bar and cutter, it is characterized in that: the left end of knife bar is cone (2), cone (2) coordinates with the cone in boring spindle hole, there is internal thread hole (1) in the axle center of cone (2), be connected by metric thread with the connecting rod of boring spindle, play tensioning function, the right-hand member of knife bar is shoulder axle (4,6), the right-hand member of shoulder axle (4,6) has respectively left and right cutter fixing hole (9,8) radially, fixing left and right boring cutter (5,7) respectively in left and right cutter fixing hole (9,8).
