Description
Technical field
The utility model relates to a kind of numerically controlled lathe, particularly relates to a kind of numerically controlled lathe four cutter spacing knife rest double-pole nested structure.
Background technology
China's numerically controlled lathe industry achieves very great achievement under national economy keeps fast-developing and continues to implement policy of stimulating the domestic demand situation, presents fast-developing and progressive good situation.As one of the core functional components of numerically controlled lathe, although Tool-rest of Numerical Control Lathe achieves comparatively much progress, compared with external level, still have a certain distance, become one of bottleneck factor of dictates host development.At present, numerically controlled lathe four cutter spacing knife rest obtains general application in numerically controlled lathe, in the process of processing endoporus, each broach shell draw-in groove of existing numerically controlled lathe four cutter spacing knife rest can only block to be established a broach shell, installs and one roughing cutting knife is first carried out roughing to inner hole of workpiece, the angle of numerically controlled lathe four cutter spacing knife rest is rotated after processing, carry out fine finishining by fine finishining cutting knife to inner hole of workpiece, working (machining) efficiency is low.
Utility model content
Technical problem to be solved in the utility model is: provide the numerically controlled lathe four cutter spacing knife rest double-pole that a kind of working (machining) efficiency is high nested structure.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: numerically controlled lathe four cutter spacing knife rest double-pole nested structure, comprise: four cutter spacing tool holder body, be arranged on the L-type broach shell in four cutter spacing tool holder body and some knife rest set bolts, described L-type broach shell is provided with roughing cutting knife installing hole and fine finishining cutting knife installing hole, aperture 0.01mm ~ the 0.05mm larger than the diameter of cutting knife cutter hub of described roughing cutting knife installing hole and fine finishining cutting knife installing hole, the L-type broach shell of described roughing cutting knife installing hole upper end is provided with the bolt positioning hole cooperatively interacted with knife rest set bolt, the L-type broach shell of described fine finishining cutting knife installing hole upper end is provided with the installing hole and the second set bolt that cooperatively interact with it.
In order to solve the problems of the technologies described above better, the further technical scheme that the utility model adopts is: described roughing cutting knife installing hole and fine finishining cutting knife installing hole are respectively arranged with anti-rotation plane.
The utility model has the advantages that: above-mentioned numerically controlled lathe four cutter spacing knife rest double-pole nested structure, in the process of processing endoporus, do not need the angle changing numerically controlled lathe four cutter spacing knife rest just can use to carry out endoporus to workpiece to carry out roughing and fine finishining, thus improve the working (machining) efficiency of lathe.

Detailed description of the invention
Particular content of the present utility model is described in detail below in conjunction with the drawings and specific embodiments.
As Fig. 1, Fig. 2, shown in Fig. 3, numerically controlled lathe four cutter spacing knife rest double-pole nested structure, comprise: four cutter spacing tool holder body 1, be arranged on the L-type broach shell 2 in four cutter spacing tool holder body 1 and some knife rest set bolts 3, described L-type broach shell 2 is provided with roughing cutting knife installing hole 4 and fine finishining cutting knife installing hole 5, aperture 0.01mm ~ the 0.05mm larger than the diameter of cutting knife cutter hub of described roughing cutting knife installing hole 4 and fine finishining cutting knife installing hole 5, the L-type broach shell 2 of described roughing cutting knife installing hole 4 upper end is provided with the bolt positioning hole 6 cooperatively interacted with knife rest set bolt 3, the L-type broach shell 2 of described fine finishining cutting knife installing hole 5 upper end is provided with the installing hole and the second set bolt 7 that cooperatively interact with it.
As shown in Figure 1, Figure 2, Figure 3 shows, in this example, described roughing cutting knife installing hole 4 and fine finishining cutting knife installing hole 5 are respectively arranged with anti-rotation plane 8.
When above-mentioned numerically controlled lathe four cutter spacing knife rest double-pole nested structure is installed, L-type broach shell 2 is fastened in the broach shell draw-in groove 9 in four cutter spacing tool holder body 1, roughing cutting knife 10 is inserted in roughing cutting knife installing hole 4, screw off knife rest set bolt 3, knife rest set bolt 3 stretches in roughing cutting knife installing hole 4 through bolt fixing hole 6 and is compressed by roughing cutting knife 9, fine finishining cutting knife 11 is inserted in fine finishining cutting knife installing hole 5, screw off the second set bolt 7, second set bolt 7 to stretch in fine finishining cutting knife installing hole 5 fine finishining cutting knife 11 is compressed.
Above-mentioned numerically controlled lathe four cutter spacing knife rest double-pole nested structure, in the process of processing endoporus, does not need the angle changing numerically controlled lathe four cutter spacing knife rest just can use to carry out endoporus to workpiece to carry out roughing and fine finishining, thus improves the working (machining) efficiency of lathe.
