The invention aims to provide an end face grooving cutter body which can process end face grooves with different specifications and has a large adjusting range.
In order to achieve the purpose, the end face grooving cutter body comprises a cutter holder connected with a main shaft of a machine tool, a sliding cutter holder is arranged on the cutter holder, the sliding cutter holder is matched with the cutter holder in a guiding mode through a guiding protrusion and a guiding groove, the sliding cutter holder is fixed on the cutter holder through a locking bolt, an opening through which the locking bolt penetrates is a round hole in the sliding cutter holder, a long hole through which the locking bolt penetrates is formed in the cutter holder, the long axis of the long hole is parallel to the guiding moving direction of the sliding cutter holder, a sliding groove extending along the long axis direction of the long hole is formed in one end, far away from the sliding cutter holder, of the cutter holder, and a nut connected with. The tool apron of the end face grooving tool body is provided with the long hole for adjustment, and the hole in the sliding tool holder is a round hole, so that the size of the connecting hole in the tool apron is not limited, the adjusting range is larger, and grooving operation of an end face groove with a larger diameter is favorably realized.
Further, the chute is arranged on the outer peripheral surface of the tool apron. Therefore, the sliding tool holder can be connected to the tool holder when the tool holder is long, and the diameter processing range of the end surface groove is enlarged.
Further, the cross section of the nut perpendicular to the axis of the threaded hole is trapezoidal, and the area of the bottom surface of the nut is larger than that of the top surface of the nut. Therefore, the top surface with the smaller area can expose more parts when the nut is arranged in the sliding groove, so that sharp parts are reduced, the operation is safer, the rotation resistance is reduced, and the cutter is more attractive.
Furthermore, the circumferential surface of the tool apron is provided with a threaded hole extending along the guide direction of the long hole, and an adjusting screw rod used for pushing the locking bolt is arranged in the threaded hole. Therefore, when the sliding tool holder needs to be adjusted, the locking bolt can be pushed by the adjusting screw rod, the adjustment is accurate, and the operation is quick.
Further, the sliding tool holder is of a cuboid structure. Therefore, the cost is low, and the processing is simple.
Furthermore, a tool connecting hole for inserting a tool bar of a tool is further formed in the end face, perpendicular to the penetrating direction of the locking bolt, of the sliding tool holder, and fastening threaded holes are formed in the circumferential face of the sliding tool holder. The guide rod can thus be fixed to the sliding tool holder and the tool holder can be further fixed by placing a screw in the clamping threaded bore.
Furthermore, a boss is arranged on the sliding tool holder, the tool connecting hole is formed in the boss, and round holes for the locking bolts to penetrate through are formed in two sides of the boss. This increases the strength of the connection of the tool holder to the sliding tool holder and corrects the cutting edge of the cutting head to be parallel to the guide projection.
Furthermore, the peripheral surface of the boss is provided with an avoiding groove for avoiding the head part of the locking bolt.
Further, the cross-sectional shapes of the guide protrusions and the guide grooves are triangular. The positioning accuracy of the sliding teeth with the triangular sections is high, the guide protrusions and the guide grooves can be in gapless fit, the machining rigidity of the cutter is increased, the sliding teeth automatically slide during installation, the centering effect is achieved, and positioning is fast.
