Description
Technical field
The utility model relates to a kind of lathe accessories field, relates in particular to a kind of Novel drilling device relevant.
Background technology
Existing drill bit is installed tool rest in the time of deep hole machining, and shock resistance and poor stability while there is drilling, cause drill bit often easily to fracture, need to often change, but its tool changing is very inconvenient, tool change time is long, cause enterprises production efficiency very low, quality precision is difficult to ensure.
Utility model content
For overcoming the low deficiency of existing drilling technique production efficiency, provide a kind of Novel drilling device.
In order to overcome the defect existing in background technology, the utility model by the following technical solutions: Novel drilling device, comprises new drill, collet, pull bar, lock-screw, tool rest, knife bar cover, locking nut.It is characterized in that: described new drill is loaded in collet; Described collet is loaded in the nose circle taper hole of knife bar cover, forms taper fit with knife bar cover; Described pull bar is threaded onto in knife bar cover, and the two ends of pull bar are provided with external screw thread; The internal thread of described collet forms and is threaded with the external screw thread of pull bar one end; Described locking nut is arranged at the rear end of knife bar cover, forms threaded engagement with the pull bar external screw thread that runs through knife bar cover; External cylindrical surface one end of described locking nut is annular knurl, and the other end is that square is for spanner locking nut; Described knife bar cover is threaded onto in the cylindrical hole of tool rest, and the U-shaped groove being put by knife bar is located; Described tool rest exterior cross-section quadrate, the upper surface of tool rest is provided with three screwed holes that run through cylindrical hole; Described lock-screw is installed in screwed hole for locking knife bar cover.
The utility model structural design is ingenious, has solved existing drill-bit installing seat tool changing inconvenience, and tool change time is long, the problems such as shock resistance and poor stability.
