Cubic boron nitride cutter arbor

Technical Field

The utility model relates to the field of cubic boron nitride cutters, in particular to a cutter bar of a cubic boron nitride cutter.

Background

The cubic boron nitride blade is synthesized by cubic boron nitride micro powder and a small amount of bonding agent by a manual method under the conditions of high temperature and high pressure, and the hardness of the cubic boron nitride blade is only inferior to that of diamond and is far higher than that of other materials, so the cubic boron nitride blade and the diamond cutter are collectively called as a superhard cutter. The early cubic boron nitride blade mainly comprises a welding composite sheet, is still widely applied, and is characterized by being capable of realizing high-speed and high-efficiency machining and even replacing grinding by turning, but in the actual production of cutting machining, in the fields of a plurality of discontinuously machined hardened steels, hard cast irons, gray cast irons, sand inclusion and white cast irons, the composite welding cubic boron nitride (PCBN) blade is frequently broken and cut, so that the integral cubic boron nitride blade appears.

However, the existing cubic boron nitride is simple to mount, the mounting distance of the blade on the cutter bar cannot be manually adjusted, and meanwhile, small-particle dust or long metal wires can splash everywhere in the polishing process and even splash into a groove at the top of a machine to be treated very difficultly.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Embodiment 1 as shown in fig. 1 to 4, a cubic boron nitride cutter bar comprises a sliding seat 1 and a sliding column 2 capable of sliding on the sliding seat, wherein the sliding seat is mounted on a milling machine and other machinery when in use, a wedge-shaped groove 3 is formed in the sliding seat, a sliding block 4 is arranged at the upper end of the sliding column, the sliding block 4 and the wedge-shaped groove 3 are matched and clamped in the wedge-shaped groove, the sliding block can slide along a sliding groove under the action of the wedge-shaped groove, if the sliding seat is transversely mounted on a milling machine, the sliding block transversely slides, and if the sliding seat is vertically mounted on the milling machine, the sliding block vertically slides. The utility model discloses a sliding column is used for the setting of sliding column lower extreme for the spliced pole 5 that is used for installing the boron nitride sword, and is equipped with mounting hole 6 on the spliced pole, and mounting hole 6 is used for the setting cubic boron nitride sword, and the spliced pole is with cubic boron nitride sword 12 fixed mounting back, and cubic boron nitride sword 12 can finely tune along with sliding column oscilaltion or lateral shifting, and the distance that the modulation is fit for the operation because the transfer of manipulator is rough action, the transfer in this application file is the fine setting.

Install between slide and the slider and be used for fixed slide block spacing subassembly on the slide, spacing subassembly in this embodiment includes align to grid in the screw hole 7 of wedge inslot, and the penetrating design of screw hole 7, threaded hole movable mounting has the screw 8 that is used for blocking the slider, screw 8 be two and with the screw hole phase-match, after the slider slides certain position promptly, two screws block respectively in the threaded hole of slider upper and lower two places, be about to the slider card die, no longer rock. The slider forms the mutually perpendicular book shape with the spliced pole cross-section, and the screw hole of the below of the slider and the distance of slider apart from the slide bottom more are favorable to observing to the book shape.

When the sliding block rises to a certain distance, the wedge-shaped groove 3 below the sliding block can be exposed, dust is easily hidden in the wedge-shaped groove 3, and the sliding block is not easy to clean; the connecting column is also provided with a clapboard component for separating dust in the wedge-shaped groove, the clapboard component comprises a clapboard 9, the connecting column is provided with a clamping groove 10, the clamping groove 10 is positioned on the back surface of the connecting column, namely on the surface opposite to the cubic boron nitride, the clapboard is clamped in the clamping groove, the clapboard is also provided with a fixing part for fixing the clapboard, the fixing part comprises a connecting rod 11 arranged on the clapboard, the connecting rod 11 is in a folded shape, the other end of the connecting rod 11 can be inserted into a threaded hole of the wedge-shaped groove along the back of the sliding seat, the connecting rod is hinged on the clapboard, namely, after the sliding block is fixed and limited, the clapboard is clamped in the clamping groove 10 of the connecting column, then the connecting rod is pulled to be inserted into the threaded hole on the back of the sliding seat, the clapboard can be fixed, when the threaded hole into which the connecting rod is inserted is exactly the same as the threaded hole into which is clamped with the limiting sliding block, the connecting rod can be slightly rotated (because the connecting rod is hinged on the clapboard), inserting the tie rod into another nearby threaded hole is irrelevant even if the partition is pulled to deform and incline, because the partition is required to cut off the wastes such as dust and the like, and the partition is not necessarily horizontal.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the utility model.
