Detailed Description
A processing cutter for processing a high-coaxiality forward and reverse hole comprises a cutter handle 1 and a cutter bar 2 arranged at the lower part of the cutter handle 1;
The cutter bar 2 is provided with a reverse boring cutter 3 and a forward boring cutter 4 at intervals along the axial direction, the reverse boring cutter 3 and the forward boring cutter 4 are respectively used for processing upper and lower holes of a workpiece 6, and the longitudinal distance between the reverse boring cutter 3 and the forward boring cutter 4 is satisfied when one boring cutter processes a corresponding hole, so that the other boring cutter does not contact with the hole processed correspondingly.
The reverse boring cutter 3 and the forward boring cutter 4 are detachably connected to the cutter bar 2.
The tool bar 2 is provided with a mounting hole, and the reverse boring tool 3 and the forward boring tool 4 are tightly connected to the tool bar 2 through the mounting hole by penetrating a locking nut 5.
A circulation hole 7 is axially arranged in the cutter bar 2, the circulation hole 7 is communicated with the mounting hole, and a lubricating medium is arranged in the circulation hole 7.
The cutter bar 2 comprises a large rod 21 and a small rod 22 which are integrally arranged, the large rod 21 is connected to the cutter handle 1, and the small rod 22 is used for installing the reverse boring cutter 3 and the forward boring cutter 4.
Following the utility model discloses make further explanation to better understand the utility model discloses: the utility model discloses a positive and negative boring cutter mainly comprises following part: a knife handle 1; a cutter bar 2; a boring cutter 4 blade; 3, reverse boring cutter blade 3; and locking the nut 5. When the machine tool works, the tool body is arranged on a main shaft of the machining equipment, the main shaft moves from top to bottom and reaches the position of a hole A, and the reverse boring tool 3 is tangent to feed along the inner circle of the hole A to complete machining of the hole A. Then, the cutter is reset to the axis of the hole A, and the cutter is lifted upwards to the height of the hole B. And the positive boring cutter 4 feeds along the inner circle of the hole B in a tangent manner to complete the processing of the hole B, so that the processing of the hole A and the hole B is completed under the condition of not turning the rotary table. Because the whole machining process only needs the movement of the main shaft and does not have the radial overturning of the clamp, the coaxiality of the two holes is greatly improved, and the machining beat is obviously reduced; the coaxiality precision is reduced to within phi 0.03 from original phi 0.08, and the processing beat is saved by 8-10 seconds.
The utility model has the advantages that the knife handle 1 and the knife bar 2 are made of high-strength 40 Cr; the positive and negative boring cutters adopt replaceable PCD blades, the distance between the positive boring cutter 4 blade and the negative boring cutter 3 blade needs to ensure that the hole B cannot be touched when the hole A is machined, and the hole A cannot be touched when the hole B is machined.
