Abstract
The invention discloses an anti-break support threading cutter. The anti-break support threading cutter comprises an arm (1), a boring rod (2), a steel block (3), a thrust bearing (4), a strong spring (5) and a stopper (6). A finish reaming hole is formed in the steel block (3) for accommodating the boring rod (2); and the tail end of the boring rod (2) is fixedly connected with the thrust bearing (4). The steel block (3) is fixed on a small tool post by a strong bolt. The arm (1) is fixed in a concave part, cut in the steel block (3), of the back end of the boring rod (2) by a pin, and is pressed against the stopper (6) by the strong spring (5). When the turning is hindered, the arm (1) can drive the boring rod (2) to overcome the pressure of the spring to rotate, so that the stress of the boring rod (2) is cushioned to prevent the break.
Description
Technical field
the present invention relates to a kind of mechanical part.
Background technology
threading tool belongs to the one of cutting tool, is used to a kind of cutter of the machining of carrying out screw thread on turnery processing lathe.Threading tool is divided into internal screw cutting tool and the large class of external screw cutting tool two, the threading tool of the threading tool of the welding cutter head of the manual mill of needs used from the machine-building initial stage, threading tool that high speed steel material is worn into, high-speed steel chasing tool chip and clip type threading tool etc., clip type threading tool is the clip type threading tool be widely used at present, clip type threading tool is divided into knife bar and blade two parts, knife bar is equipped with edge bearing, with screw in compression, blade is arranged on edge bearing, blade is divided into again the non-coated chip of carbide alloy, hard alloy coated blade.
the boring bar of existing screwer, due to more elongated, be easily subject to external force and fracture.
Summary of the invention
In order to solve the problems of the technologies described above, the present invention includes: arm, boring bar, bloom, thrust bearing, strong spring and block.Bloom offers and finish reams hole to hold boring bar, boring bar end is fixedly connected with thrust bearing.Bloom strength bolt is fixed on small tool.An arm 1 fixed by the recess pin cut in bloom in the rear end of boring bar, is pressed against on block by arm by strong spring.
Beneficial effect: when turning meets with obstruction, arm can drive boring bar to overcome spring pressure and rotate, and makes stressed buffering of boring bar and unlikelyly to fracture.
Accompanying drawing explanation
fig. 1 is schematic diagram of the present invention.
Detailed description of the invention
As shown in Figure 1, the present invention includes: arm 1, boring bar 2, bloom 3, thrust bearing 4, strong spring 5 and block 6.Bloom 3 offers and finish reams hole to hold boring bar 2, boring bar 2 end is fixedly connected with thrust bearing 4.Bloom 3 is fixed on small tool with strength bolt.An arm 1 fixed by the recess pin cut in bloom 3 in the rear end of boring bar 2, is pressed against on block 6 by arm by strong spring 5.When turning meets with obstruction, arm 1 can drive boring bar 2 to overcome spring pressure and rotate, and makes stressed buffering of boring bar 2 and unlikelyly to fracture.
