Abstract
The utility model relates to a boring tool which comprises a tool rod and a tool body. The left end of the tool rod is a cone which is matched with a cone of a main shaft hole of a boring mill, an inner threaded hole is formed in the axis of the cone of the tool rod and is connected with a connecting rod of a main shaft of the boring mill through metric threads, and a tensioning effect is achieved; the right end of the tool rod is provided with shouldered shafts, a radial left tool fixing hole and a radial right tool fixing hole are formed in the right ends of the shouldered shafts respectively, and a left boring tool body and a right boring tool body are fixed in the left tool fixing hole and the right tool fixing hole respectively. The boring tool is simple in structure and can machine hole diameters which exceed the machining range of a device.
Description
Technical field
The utility model 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 ensure the axiality between the depth of parallelism and two holes of its aperture and base end face, 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, bring very large difficulty to machined.
Traditional processing method is to machine disposable two apertures, 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 utility model provides a kind of boring cutter, and it is simple in structure, and the aperture that can realize exceeding beyond the equipment range of work processes.
The technical scheme in the invention for solving the technical problem is: 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, the interior left and right boring cutter of fixing respectively.
The utlity model has following advantages: the aperture that 1, can realize exceeding beyond the equipment range of work processes, ensure 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.
Brief description of the drawings
Below in conjunction with drawings and Examples, this utility model is further illustrated.
Fig. 1 is the utility model cutaway view.
Detailed description of the invention
As shown in Figure 1, the utility model comprises 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 left and right boring cutter 5,7 of fixing 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.
