Description
Technical Field
The utility model relates to the technical field of flange machining equipment, in particular to a reverse boring and milling cutter for machining a flange.
Background
The conventional milling cutter gradually extends the spindle (or the workpiece is gradually close to the spindle) during boring, namely, forward boring, and conversely, the milling cutter gradually shortens the spindle (or the workpiece is gradually far away from the spindle) during boring, namely, backward boring. Reverse boring is typically used when a smaller bore located between the boring location and the spindle is used to machine a larger bore (i.e., a stepped bore).
At present, when a reverse boring and milling cutter is used for machining a stepped hole in a flange, because a working face is arranged below a workpiece, cutting fluid is difficult to directly cool the cutter, and the cutter is easy to damage.

The utility model is realized by adopting the following technical scheme: the reverse boring milling cutter for flange machining comprises a cutter bar, wherein a notch is formed in the lower portion of the cutter bar, a rotating shaft and a cutter rotating around the rotating shaft are arranged in the notch, the outer wall of the cutter is matched with the outer wall of the cutter bar to form a cylinder, a liquid conveying pipe is arranged in the cutter bar, one end of the liquid conveying pipe is closed, the other end of the liquid conveying pipe is opened and extends into the notch, at least two through holes communicated with the liquid conveying pipe are formed in the outer wall of the cutter bar, the two through holes are arranged in a staggered mode, and a cooling liquid conveying mechanism corresponding to the through holes one to one is further arranged on the outer wall of the cutter bar;
the cooling liquid conveying mechanism comprises a liquid inlet pipe and a sliding seat rotating around the cutter bar, one end of the liquid inlet pipe is communicated with the cooling liquid storage tank, the other end of the liquid inlet pipe is communicated with the inner wall of the sliding seat, and the axis of the liquid inlet pipe is in the same horizontal plane with the axis of the through hole.
The inner wall of the sliding seat is provided with two end-to-end sliding grooves at intervals, the outer wall of the cutter bar is provided with two annular limiting strips at intervals, and the two limiting strips are respectively arranged in the two sliding grooves in a one-to-one correspondence manner and slide in the sliding grooves.
The through hole and the liquid inlet pipe are positioned between the pair of limiting strips.
The inner diameter of the liquid inlet pipe is smaller than that of the through hole.
Compared with the prior art, in the process of the rotation of the cutter bar, the sliding seat and the liquid inlet pipe are kept static, and the liquid inlet pipe is closed and cooling liquid cannot leak due to the fact that the inner wall of the sliding seat is tightly attached to the outer wall of the cutter bar; when the axis of the through hole rotates to coincide with the axis of the liquid inlet pipe and the through hole is aligned with the pipe orifice of the liquid inlet pipe, the liquid inlet pipe and the through hole are in a communicated state, cooling liquid enters the liquid conveying pipe through the through hole, and then the liquid conveying pipe sprays the cooling liquid to the cutter to realize reliable cooling of the cutter, so that the machining effect is ensured to be reliable, and the service life of the cutter is prolonged.

in the figure: 1. a cutter bar; 11. a notch; 12. a through hole; 13. a limiting strip; 2. a rotating shaft; 3. a cutter; 4. a transfusion tube; 5. a liquid inlet pipe; 6. a slide base; 60. a chute.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that any combination of the embodiments or technical features described below can be used to form a new embodiment without conflict.
As shown in fig. 1-2, the reverse boring and milling cutter for flange processing comprises a cutter bar 1, wherein a notch 11 is formed in the lower portion of the cutter bar 1, a rotating shaft 2 and a cutter 3 rotating around the rotating shaft 2 are arranged in the notch 11, the outer wall of the cutter 3 is matched with the outer wall of the cutter bar 1 to form a cylindrical shape, a liquid conveying pipe 4 is arranged in the cutter bar 1, one end of the liquid conveying pipe 4 is closed, the other end of the liquid conveying pipe 4 is opened and extends into the notch 11, at least two through holes 12 communicated with the liquid conveying pipe 4 are formed in the outer wall of the cutter bar 1, the two through holes 12 are arranged in a staggered manner, and a cooling liquid conveying mechanism corresponding to the through holes 12 is further arranged on the outer wall of the cutter bar 1;
the cooling liquid conveying mechanism comprises a liquid inlet pipe 5 and a sliding seat 6 rotating around the cutter bar 1, one end of the liquid inlet pipe 5 is communicated with a cooling liquid storage tank, the other end of the liquid inlet pipe is communicated with the inner wall of the sliding seat 6, and the axis of the liquid inlet pipe 5 is in the same horizontal plane with the axis of the through hole 12. When the cutter bar 1 rotates reversely, the cutter 3 rotates around the rotating shaft 2 to the outside of the gap 11 to perform reverse boring cutting, the sliding seat 6 and the liquid inlet pipe 5 are kept static in the rotating process of the cutter bar 1, and the liquid inlet pipe 5 is closed and cooling liquid cannot leak due to the fact that the inner wall of the sliding seat 6 is tightly attached to the outer wall of the cutter bar 1; when the axis of the through hole 12 rotates to coincide with the axis of the liquid inlet pipe 5 and the through hole 12 is aligned with the pipe orifice of the liquid inlet pipe 5, the liquid inlet pipe 5 and the through hole 12 are in a communicated state, cooling liquid enters the liquid conveying pipe 4 through the through hole 12 and is sprayed to the cutter 3 through the liquid conveying pipe 4, so that the cutter 3 is reliably cooled, the machining effect is ensured to be reliable, and the service life of the cutter 3 is prolonged; further, through setting up a plurality of coolant liquid conveying mechanism and to the dislocation set of through-hole 12, it is long when having improved feed liquor pipe 5 and through-hole 12's intercommunication, just also improved the delivery capacity of coolant liquid, show improvement cooling effect.
