Description
Technical field
The utility model relates to a kind of elongated blind hole internal keyway cutter, belongs to machining tool field.
Background technology
Cutter is the instrument for machining in machine-building, in lathe process, often uses various cutter by work pieces process inner circle, cylindrical and annular grooving etc.
When processing trapezoidal screw axle head blind hole internal keyway, conventional tool is the embedding high-speed steel cutter head of steel knife bar, and when steel knife bar is accomplished so thin, cannot embed cutter head and cutter head screw, because knife bar is meticulous, cutter relieving phenomenon is very serious.Because of end-face hole and keyway too small, traditional shaping machine plane key cutter hand-hole depth as shallow, and rigidity is not enough, after causing use a period of time, affect the precision of processing parts, cutting-tool's used life is not long yet.
Utility model content
The purpose of this utility model is to provide a kind of elongated blind hole internal keyway cutter, there is higher rigidity, be more suitable for processing slim female keyway, successfully solve cutter relieving problem, have into hole depth dark, machining accuracy be high, cost is low, the advantage that effective, cutter life is long.
For achieving the above object, the utility model is achieved through the following technical solutions:
The elongated blind hole internal keyway cutter that the utility model provides, comprise tool post, tool post is provided with cutter head, tailstock is fixedly connected tool post, tool post is provided with screw thread near one end of tailstock, screw thread is provided with locking nut, the other end of tool post is provided with cutter hub groove, holding integrated high-speed steel cutter hub in cutter hub groove, the front end of overall high-speed steel cutter hub is provided with cutter head, gland is provided with above cutter hub groove, gland is provided with fastening screwed hole on gland fixing hole and cutter hub, the side of cutter hub groove is provided with cutter hub side fastening screw pit, gland fixing hole, on cutter hub, fastening screwed hole and cutter hub side fastening screw pit are respectively equipped with set bolt.
On cutter hub, fastening screwed hole is positioned in gland medial axis, and on cutter hub, fastening screwed hole is just to cutter hub groove, and on cutter hub, fastening screwed hole is provided with 2 ~ 4, and the both sides of gland fixed hole position fastening screwed hole on cutter hub, gland fixing hole is provided with 4 ~ 8.
Cutter hub side fastening screw pit is provided with 2 ~ 4.Compress overall high-speed steel cutter hub by the bolt putting into fastening screwed hole on cutter hub side fastening screw pit and cutter hub, the rigidity of overall high-speed steel cutter hub is got a promotion, be more suitable for processing internal keyway.
The utility model compared with prior art, has following beneficial effect:
The utility model has higher rigidity, is suitable for processing slim female keyway, successfully solves cutter relieving problem, has into hole depth dark, machining accuracy is high, cost is low, the advantage that effective, cutter life is long.

Detailed description of the invention
Below in conjunction with embodiment, the utility model is described in further detail.
As shown in the figure, elongated blind hole internal keyway cutter described in the utility model, comprise tool post 2, tool post 2 is provided with cutter head 7, it is characterized in that tailstock 8 is fixedly connected tool post 2, tool post 2 is provided with screw thread near one end of tailstock 8, screw thread is provided with locking nut 1, the other end of tool post 2 is provided with cutter hub groove 10, holding integrated high-speed steel cutter hub 4 in cutter hub groove 10, the front end of overall high-speed steel cutter hub 4 is provided with cutter head 7, gland 3 is provided with above cutter hub groove 10, gland 3 is provided with fastening screwed hole 6 on gland fixing hole 5 and cutter hub, the side of cutter hub groove 10 is provided with cutter hub side fastening screw pit 9, gland fixing hole 5, on cutter hub, fastening screwed hole 6 and cutter hub side fastening screw pit 9 are respectively equipped with set bolt, on cutter hub, fastening screwed hole 6 is positioned in gland 3 medial axis, and fastening screwed hole 6 is just to cutter hub groove 10 on cutter hub, on cutter hub, fastening screwed hole 6 is provided with 2 ~ 4, gland fixing hole 5 is positioned at the both sides of fastening screwed hole 6 on cutter hub, gland fixing hole 5 is provided with 4 ~ 8, cutter hub side fastening screw pit 9 is provided with 2 ~ 4.
The utility model in use, overall high-speed steel cutter hub 4 is put into cutter hub groove 10, , gland 3 covers on cutter hub groove 10, gland fixing hole 5 is passed gland 3 and cutter hub seat 2 fixation with bolt, on cutter hub, fastening screwed hole 6 and cutter hub side fastening screw pit 9 put into bolt respectively simultaneously, realize by tighting a bolt compressing overall high-speed steel cutter hub 4, after set of knives dress, can be used on planer, the fixing of cutter and planer is realized by locking nut 1, after cutter and workpiece are fixed, slow moving cutting tool tool setting, overall high-speed steel cutter hub 4 is made to put into elongated blind hole 12, internal keyway 11 is processed by moving back and forth of cutter.The new structure of this cutter improves the rigidity of cutter, achieves the processing of elongated blind hole internal keyway, solves cutter relieving problem.
In sum, the utility model is more suitable for processing slim female keyway, successfully solves cutter relieving problem, have into hole depth dark, the advantage that machining accuracy is high, cost is low, effective, cutter life is long, also improves the production efficiency of enterprise simultaneously, reduces production cost.
