Description

Technical Field

[0001] The utility model relates to the field of machine tool cutters, in particular to a cutter head for a sharpening machine. Background Art

[0002] The existing cutterhead is relatively thin, so most of them use protruding bolts to fix the blades. When in use, the chips generated by cutting will be blocked by the protruding bolts, causing the chips to accumulate at the blade and block the chip removal. Utility Model Content

[0003] To solve the above problems, the purpose of the present invention is to provide a tool disc for a sharpening machine, which can install the blade with a countersunk screw through the protruding part of the disc body, thereby facilitating the discharge of debris and preventing blockage.

[0004] The utility model provides a tool disc for a sharpening machine, comprising a disc body and blades, the blades being arranged on the disc body in a ring, the disc body being provided with a chip groove that fits with the blades, the middle portion of the disc body being protruding, the blades being mounted on the chip groove, and being connected and fixed with a plurality of countersunk screws.

[0005] Furthermore, the outer side of the chip groove is wider and connected to the thinner part of the edge of the disk body. The upper part of the chip groove is a vertical through hole, and the lower part is a funnel shape with one side tilted. The blade is installed on the inclined side wall of the chip groove.

[0006] Furthermore, the lower end of the blade protrudes from the disc body, and the upper end is also higher than the disc body.

[0007] Furthermore, a bevel is provided on the top of the blade, and the bevel on the top of the blade abuts against the side wall of the upper part of the vertical through hole of the chip groove.

[0008] Beneficial effects: 1. The middle part of the disc body is protruding, and the blade is installed on the chip groove and is fixed with multiple countersunk screws. Different from the traditional screw installation of the blade, it will not block the debris, thereby preventing blockage.

[0009] 2. The upper part of the chip groove is a vertical through hole, and the lower part is a funnel shape with one side tilted. The blade is installed on the inclined side wall of the chip groove. The top of the blade is provided with a bevel. The bevel on the top of the blade rests against the side wall of the vertical through hole in the upper part of the chip groove, which can make it easier to determine the installation position of the blade. When the blade is cutting, the side wall of the chip groove can rest against the top of the blade to prevent the blade from sliding loose. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0015] The disclosure below provides many different embodiments or examples for realizing different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present invention.

[0016] Below, the cutter head for sharpening machine according to the embodiment of the present invention is described with reference to the accompanying drawings. Figure 1 and Figure 2 As shown, the tool disc for sharpening machines includes a disc body 1 and a blade 2, the blade 2 is arranged on the disc body 1, the middle part of the disc body 1 protrudes, and the disc body 1 is provided with a chip groove that fits with the blade 2, the outer side of the chip groove is wider and connected to the thinner part of the edge of the disc body 1, the upper part of the chip groove is a vertical through hole, and the lower part is a funnel shape with one side inclined, the blade 2 is installed on the inclined side wall of the chip groove, and is fixed with a plurality of countersunk screws, the lower end of the blade 2 protrudes from the disc body 1, and the upper end is also higher than the disc body 1, the top of the blade 2 is provided with a bevel, and the top bevel of the blade 2 presses against the side wall of the vertical through hole in the upper part of the chip groove, thereby limiting the position.

[0017] In a specific embodiment: the disc body 1 is installed on a power device and rotates, so that the blade 2 cuts the bar material below, and at the same time, the debris generated by the cutting is discharged to the blade 2 through the guide of the blade 2. During the process, the countersunk screw will not block the debris, so that the debris can be discharged quickly. At the same time, the rotation of the disc body 1 will discharge part of the debris through the edge of the blade 2, thereby speeding up the discharge speed of the debris and preventing blockage.

[0018] Working principle: The disc body 1 is installed on the power device and rotates, so that the blade 2 cuts the bar material below. At the same time, the debris generated by the cutting is discharged to the blade 2 through the guide of the blade 2. During the process, the countersunk screw will not block the debris, so that the debris can be discharged quickly. At the same time, the rotation of the disc body 1 will discharge some of the debris through the edge of the blade 2, thereby speeding up the discharge of the debris and preventing blockage.
