Abstract
The utility model discloses a deep hole processing tool which comprises a round tool bar and a drill bit. The tool bar comprises a connection part and a lengthening part, wherein a locating hole is formed inside the end of the connection part, a locking hole is formed in a wall of the connection part, the drill bit is provided with a clamping portion, the clamping portion and the locating hole are matched with each other and connected with each other in a side pressure compression mode, and the diameter of the lengthening part of the tool bar is bigger than that of the connection part. The diameter of the deep hole processing tool is enlarged, integrate intensity of the tool is improved, and consumption cost of the tool is reduced.
Description
Technical field
The utility model relates to a kind of deep hole processing cutter.
Background technology
In the machining, the deep hole machining especially processing of elongated hole is a difficult problem in the machining, and its difficult point is because general cutter is elongated, poor rigidity, intensity are low, easily causes the cutter deflection, thereby does not reach the requirement of crudy.Consider the requirement of cutter wilfulness and rigidity, generally adopt U to bore or the Integral alloy drill bit, but it is expensive, is difficult to the controlled working cost.Therefore, with conventional equipment deep hole machining, elongated hole, do not have under the special equipment of deep hole machining, the design of cutter is extremely important.
Summary of the invention
The utility model purpose provides a kind of cutter that is suitable for deep hole machining.
For achieving the above object, adopt following technical scheme:
A kind of deep hole processing cutter comprises circular knife bar and drill bit, and knife bar comprises coupling part and elongated portion, in the end of coupling part locating hole is arranged, locking hole is arranged on the wall, retained part is arranged on the drill bit, retained part and locating hole agree with, and connect by side compression type compression mode.
Further, the diameter of knife bar elongated portion is greater than the coupling part.
The knife bar material can be used the 40cr steel, and surface hardening is processed.
Drill bit can require to select high-speed steel or Integral alloy material according to the aperture.
Deep hole processing cutter of the present utility model, the knife bar enlarged diameter has improved the bulk strength of cutter, reduces the cutter consuming cost.
Description of drawings
Fig. 1 is the lever structure schematic diagram of cutter of the present utility model;
Fig. 2 is the drill bit structure schematic diagram of cutter of the present utility model;
Fig. 3 is the structural representation of cutter of the present utility model;
Among the figure, 1 is locking hole, and 2 is the coupling part, and 3 is locating hole, and 4 is elongated portion, and 5 is knife bar, and 6 is the drill bit retained part, and 7 is the drill bit locking hole, and 8 is drill bit.
The specific embodiment
As shown in Figure 1, 2, 3, a kind of cutter of deep hole machining comprises circular knife bar 5 and drill bit 8, knife bar 5 overall length 220mm comprise coupling part 2 and elongated portion 4, elongated portion diameter 30mm, the diameter of coupling part 2 less ends is 25mm, there is locating hole 32 inside, coupling part, and locking hole 1 is arranged on the wall, and drill bit 8 diameters are 25mm, retained part 6 is arranged on the drill bit 8, on drill bit locking hole 7 is arranged, retained part 6 agrees with locating hole 3 on the coupling part 2, and connects by side compression type compression mode.
Claims (2)
