Detailed Description
Example one
As shown in fig. 1 and 4, an integrated cutter head assembly capable of realizing chamfering and center hole machining comprises a cutter head 1, a chamfering cutter 2, a center drill centering sleeve 3 and a center drill 4.
The cutter head 1 comprises a circular base body part 11, wherein a protruding part 12 is arranged on the base body part 11, and three chamfering cutter mounting grooves 13 are uniformly distributed in the protruding part 12 along the circumferential direction. The chamfering tool 2 is arranged in the chamfering tool mounting groove 13, as shown in fig. 2, one side of the chamfering tool mounting groove 13 is provided with a transverse jacking screw hole 14, and a transverse jacking screw (not shown) for transversely jacking the chamfering tool 2 is arranged in the transverse jacking screw hole 14. The outer end of the mounting groove (with the end far away from the circle center of the cutter head 1 as the outer end) is provided with a longitudinal jacking screw hole 15, and a longitudinal jacking screw (not shown in the figure) for longitudinally jacking the chamfer cutter 2 is arranged in the longitudinal jacking screw hole 15.
As shown in fig. 1 and 4, the protruding portion 12 is provided with a central circular hole coaxially arranged with the cutter head 1, and the central drill centering sleeve 3 is arranged in the central circular hole and is fixedly connected with the protruding portion 12 of the cutter head 1 through a centering sleeve fixing screw 6. As shown in fig. 3, a boss 12 of the cutter head 1 is provided with a centering sleeve fixing screw 6, and the centering sleeve fixing screw 6 is in threaded connection with the boss 12 of the cutter head 1. The end part of the centering sleeve fixing screw 6 penetrates through the side wall of the central round hole and is tightly pressed on the central drill centering sleeve 3, so that the central drill centering sleeve 3 is fixed.
As shown in fig. 4 and 5, a center drill 4 is disposed in the center drill centering sleeve 3, and the center drill 4 is fixedly connected to the center drill centering sleeve 3 through a center drill fixing screw 5.
During operation, the central drill bit 4 and the chamfer cutter 2 are firstly clamped in place, then the equipment is started, and in the process of driving the cutter head to rotate, the central drill bit 4 and the chamfer cutter 2 simultaneously process a workpiece, so that chamfering and center hole processing of the workpiece are realized.
Furthermore, the structure formed by the convex part 12 and the chamfer cutter mounting groove 13 is in a corresponding shape, is similar to a triangular star-shaped structure, and the number of the centering sleeve fixing screws 6 is one, and is positioned between the two chamfer cutter mounting grooves 13.
Further, as shown in fig. 6, a flat port 41 is provided in the middle of the center drill 4, and the center drill fixing screw 5 abuts against the flat port 41 of the center drill 4.
Further, as shown in fig. 6, both ends of the center drill 4 are provided with blades.
Further, as shown in fig. 7, a groove for matching with the centering sleeve fixing screw 6 is arranged on the cylindrical side surface of the centering sleeve 3 of the center drill. Preferably, the cross-section of the groove is triangular and extends through the center drill centering sleeve 3 in a direction parallel to the diameter of the center drill centering sleeve 3.
The reason for this is that: if no groove is arranged, the central drill centering sleeve 3 is easy to shift in the axial direction, and the processing process is affected. If the traditional groove with a rectangular cross section is adopted, if the size of the groove is matched with that of the centering sleeve fixing screw 6, the operation is not easy to perform during installation, and the alignment is not easy to realize; if the size of the groove is larger than that of the centering sleeve fixing screw 6, the problem of axial movement still exists although the installation is convenient, and the extending distance of the center drill 4 is not easy to control.
By designing the groove in a triangular cross-section, as shown in fig. 7, no matter which position the center drill centering sleeve 3 is pressed against, the center drill centering sleeve 3 is adjusted in an axial direction by the pressing action of the centering sleeve fixing screw 6, and finally, the position a in fig. 7 is reached. Thus, the installation operation is convenient, the strict fixation of the axial direction is realized, the extending distance of the central drill bit 4 is ensured, and the manual adjustment is not needed.
Example two
Three centering sleeve fixing screws 6 are arranged between the centering sleeve 3 of the center drill and the boss 12 of the cutter head 1, the centering sleeve fixing screws 6 and the chamfering cutter mounting groove 13 are arranged at intervals, and the rest structures are the same as those of the first embodiment.
EXAMPLE III
The groove penetrates through the central drill centering sleeve 3 along the circumferential direction to form a complete circular ring structure, and the rest structures are the same as the first embodiment.
