As shown collectively in fig. 1 to 8, the present utility model includes a cutter bar 1, a coarse blade 2, and a fine blade 3. The cutter bar 1 comprises a bar body 11 and a blade mounting seat 12 fixedly arranged at the bottom of the bar body 11 along the length direction of the bar body 11, and preferably, the bar body 11 and the blade mounting seat 12 are integrally formed, so that the strength is improved; the coarse blade 2 is detachably arranged on one side of the blade mounting seat 12; the fine blade 3 is arranged opposite to the coarse blade 2 and is detachably arranged on the other side of the blade mounting seat 12; wherein the cutting direction of the fine blade 3 is opposite to the cutting direction of the coarse blade 2.
In the present technology, when cutting the workpiece 6, the compound tool is mainly used to machine the end face groove 61 on the workpiece 6, and it should be noted that the workpiece 6 is provided with a hole, and the end face groove 61 is disposed on the outer wall of the workpiece 6 and located outside the hole.
When the workpiece 6 needs to be cut, after the workpiece 6 rotates, the workpiece 6 can be firstly rough machined through the rough blade 2, then the workpiece 6 is finished through the finish blade 3, two machining procedures are combined on one cutter, the number of the cutters is reduced, only the position of one cutter is occupied on the cutter tower 5, the cutter tower 5 is not required to be changed, the machining requirement is met, the machining range is improved, and the cutter is simple in structure and convenient to machine; meanwhile, on the basis of not changing the rotation direction of the workpiece 6, the positions of the coarse blade 2 and the fine blade 3 are changed through relative arrangement, and only the positions of the coarse blade 2 and the fine blade 3 are required to be translated, so that coarse and fine machining of the end face groove 61 on the workpiece 6 can be realized, interference to normal rotation of the workpiece 6 is avoided, cutting difficulty is reduced, and using effect is improved.
In order to reduce the processing and maintenance difficulty, the coarse blade 2 and the fine blade 3 have the same structure; wherein the coarse blade 2 rotates 180 ° around the center line of the blade mount 12 to form the fine blade 3, that is, the coarse blade 2 is opposite to the fine blade 3 and the cutting direction is opposite.
Specifically, the rough blade 2 includes a blade body 21 and two hook-shaped cutting portions 22; wherein, the two hook-shaped cutting parts 22 are arranged at two ends of the blade body 21 along the length direction of the blade body 21, and the two hook-shaped cutting parts 22 are bent towards one side of the blade body 21 along the same direction, so as to conveniently extend into the end face groove 61 on the workpiece 6 to cut the workpiece; the cutting directions of the two hook-shaped cutting portions 22 are opposite.
The blade body 21 is provided with a bolt mounting hole 23 in a penetrating manner; the hook-shaped cutting part 22 rotates 180 degrees around the axis of the bolt mounting hole 23 to form the other hook-shaped cutting part 22, so that the cutting directions of the two hook-shaped cutting parts 22 are opposite, after the end face groove 61 is cut by the hook-shaped cutting part 22 for a period of time, the machining precision is reduced due to abrasion, and after the hook-shaped cutting part rotates 180 degrees around the axis of the bolt mounting hole 23, the position of the other hook-shaped cutting part 22 can be exchanged with the position of the other hook-shaped cutting part, and the cutting is continued by using the other hook-shaped cutting part 22, so that the service life is prolonged, and the use effect is improved.
In order to facilitate the mounting of the blade on the blade mounting seat 12, the blade mounting seat 12 is concavely provided with a through groove 13 with one end open, which is arranged along the length direction of the blade body 21, the through groove 13 is used for accommodating the blade body 21 and one of the hook-shaped cutting parts 22, and the other hook-shaped cutting part 22 extends out of the through groove 13 and is positioned outside the through groove 13. When cutting, only one hook-shaped cutting portion 22 is extended out of the through groove 13 on the outer side of the insert mounting seat 12, so that cutting by the hook-shaped cutting portion 22 is facilitated, and the other hook-shaped cutting portion 22 does not affect cutting.
To facilitate cutting of the end face groove 61, both hook-shaped cutting portions 22 are bent toward the side near the insert mount 12. When cutting, the hook-shaped cutting part 22 stretches into the end face groove 61 to cut the workpiece 6, and as the workpiece 6 rotates, the hook-shaped cutting part 22 on the rough blade 2 can stretch into the end face groove 61 when rough machining is needed, and the hook-shaped cutting part 22 on the fine blade 2 can stretch into the end face groove 61 when finish machining is needed, so that both the hook-shaped cutting parts 22 bend towards the side close to the blade mounting seat 12 to facilitate rough machining and finish machining, and meanwhile, as both the hook-shaped cutting parts 22 bend towards the side close to the blade mounting seat 12, the translation distance between the hook-shaped cutting part 22 on the rough blade 2 and the hook-shaped cutting part 22 on the fine blade 2 is shortest when rough machining and finish machining are changed, the requirement that the turret 5 drives the workpiece to move is met, and the machining efficiency is improved.
In the utility model, a workpiece avoiding groove 14 is concavely arranged on the bottom surface of a blade mounting seat 12, and the workpiece avoiding groove 14 is arranged between a coarse blade 2 and a fine blade 3. Since the workpiece 6 is rotated when the face groove 61 is cut, it is necessary to avoid the tip of the workpiece 6 when the workpiece 6 is rotated for some relatively large face grooves 61, so that the cutting requirement of the face groove 61 is satisfied. Preferably, the cross-sectional shape of the workpiece escape groove 14 is V-shaped, arcuate or trapezoidal.
When the utility model is used, the compound cutter is arranged on one cutter seat 51 on the cutter tower 5, the workpiece 6 rotates, the cutter tower 5 drives the rough cutter blade 2 to extend into the end surface groove 61 for rough machining, and at the moment, the fine cutter blade 3 is positioned in a hole of the workpiece 6 and cannot influence the rough machining; when finishing is needed, the turret 5 drives the rough blade 2 to move outwards firstly to move out of the end face groove 61, then drives the fine blade 2 to move outwards, and enables the fine blade 2 to extend into the end face groove 61 to finish the end face groove, at the moment, the rough blade 2 is located in a hole of the workpiece 6, so that the influence on finishing cannot be caused, two working procedures of rough cutting and finish cutting on the workpiece 6 through a composite cutter are met, the position of one cutter is occupied on the turret 5, the change of the turret 5 is not needed, the machining requirement is met, and the machining range is improved.
The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
