Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] This embodiment provides a clutch-specific grooving cutter, and its structural schematic diagram is as follows: Figure 1-Figure 4 As shown, it includes a grooving tool body 1; the tops of both ends of the grooving tool body 1 are provided with main cutting edges 2, and the width of the main cutting edges 2 is narrower than the width of the grooving tool body 1; first bevels a are provided at the connection points between the two sides of the cutting main edges 2 and the two side surfaces of the grooving tool body 1, and the first bevel a connects the upper surface and the lower surface of the grooving tool body 1, and the first bevel a and the connection point of the upper surface of the grooving tool body 1 constitute a first secondary cutting edge. By utilizing the first secondary cutting edge formed by the connection point of the first bevel a and the upper surface of the grooving tool body 1, during the process of cutting and grooving the clutch by the cutting main edge 2, the groove opened by the clutch and the connection point of the clutch surface can be synchronously cut to form an external chamfer.

[0028] Furthermore, in the present embodiment, circular arc lobes 5 are provided on both sides of the main cutting edge 2, and the circular arc lobes 5 are connected to the upper surface and the lower surface of the grooving cutter body 1. The connection between the circular arc lobes 5 and the upper surface of the grooving cutter body 1 constitutes a second secondary cutting edge. By setting the circular arc lobes 5 and utilizing the connection between the circular arc lobes 5 and the upper surface of the grooving cutter body 1 to form a second secondary cutting edge, an inner chamfer can be formed at the angle between the side wall and the bottom wall of the groove of the clutch. The outer chamfer and the inner chamfer are formed by synchronous integrated cutting during the grooving process, and there is no need for separate grinding and cutting after grooving, which reduces the grooving process and makes the grooving process of the clutch more efficient.

[0029] Furthermore, the angle between the first bevel a and the direction perpendicular to the grooving cutter body 1 is in the range of 43° to 46°, and the inclination angle of the first bevel a adopts the traditional chamfering angle range of 43° to 46°, which has high aesthetics and strong adaptability.

[0030] As a preferred technical solution in this embodiment, the width of the grooving cutter body 1 gradually decreases from the upper surface to the lower surface. With this special structure, the main cutting edges 2 at both ends of the grooving cutter body 1 are wider at the top and narrower at the bottom, which is conducive to grooving and makes the grooving process smoother.

[0031] As a preferred technical solution in this embodiment, a second bevel b is provided at both ends of the grooving cutter body 1, and the angle between the second bevel b and the vertical direction is in the range of 14° to 17°. By setting the second bevel b at both ends of the grooving cutter body 1 and the second bevel b being inclined at a small angle of 14° to 17°, it is beneficial to the clutch cutting and grooving, and ensures the strength of the cutting main edge 2, and has high strength and durability.

[0032] As a preferred technical solution in this embodiment, a third bevel c is provided on the upper surface of the grooving cutter body 1 near the main cutting edge 2, and a circular arc concave angle 4 is provided at the junction of the third bevel c and the main cutting edge 2. A first groove 3 is provided on the upper surface of the grooving cutter body 1, and the first groove 3 is distributed along the length direction of the grooving cutter body 1, and both ends of the first groove 3 are connected to the third bevel c. The third bevel c provided on the top of the grooving cutter body 1 and the first groove 3 provided are beneficial to the reverse discharge of cutting chips, and the third bevel c adopts an angle range of 75° to 78°, and cooperates with the circular arc concave angle 4 to form a special chip curling structure, and the cutting chip curling angle is large, thereby avoiding the phenomenon that the generation of chips affects the grooving effect.

[0033] Furthermore, a second groove 7 is provided on the lower surface of the grooving tool body 1, and recessed grooves 6 are provided on both sides of the grooving tool body 1. The recessed grooves 6 connect the upper and lower surfaces of the grooving tool body 1, which is beneficial to the circulation of air during the grooving process and the dissipation of heat at the cutting main edge 2.

[0034] Working principle: Through the setting of the double-headed cutting main edge 2, it can be used alternately, which reduces the material cost and the use cost. Through the setting of the second bevel b at both ends of the grooving cutter body 1, and the second bevel b is inclined at a small angle of 14°~17°, it is not only conducive to clutch cutting and grooving, but also ensures the strength of the cutting main edge 2, and has high strength and durability. Through the setting of the first bevel a, the first secondary cutting edge formed by the connection between the first bevel a and the upper surface of the grooving cutter body 1 can be used to synchronously cut the connection between the clutch groove and the clutch surface during the clutch cutting and grooving process by the cutting main edge 2 to form an outer chamfer. Through the setting of the circular arc convex corner 5, the second secondary cutting edge is formed by the connection between the circular arc convex corner 5 and the upper surface of the grooving cutter body 1, which can form an inner chamfer at the angle between the side wall and the bottom wall of the clutch groove, and an outer chamfer. The corner and the inner chamfer are cut synchronously and integrated during the grooving process. There is no need for separate grinding and cutting after grooving, which reduces the grooving process flow and makes the grooving process of the clutch more efficient. The inclination angle of the first bevel a adopts the traditional chamfer angle range of 43° to 46°, which has high aesthetics and strong adaptability. Furthermore, the third bevel c set at the top of the grooving tool body 1 and the first groove 3 opened are beneficial to the reverse discharge of cutting chips. The third bevel c adopts an angle range of 75° to 78°, and cooperates with the circular arc concave angle 4 to form a special chip curling structure. The cutting chip curling angle is large, which avoids the phenomenon that the debris affects the grooving effect. In addition, the grooving tool body 1 adopts a special structural design in which the width gradually decreases from the upper surface to the lower surface, so that the main cutting edges 2 at both ends of the grooving tool body 1 are wide at the top and narrow at the bottom, which is beneficial to the grooving and the grooving process is smoother.

[0035] All technical features in this embodiment can be freely combined according to actual needs.
