[0002] The back angle and front angle of the V-shaped cutter are located on two relatively inclined planes. When processing the back angle and front angle of the V-shaped cutter, the body of the V-shaped cutter is first fixed on a surface grinder with a fixture, and then the body of the V-shaped cutter is ground with a grinding tool, wherein the body of the V-shaped cutter needs to be ground along one direction to process the back angle of the cutter, and the body of the V-shaped cutter needs to be ground along another direction to process the front angle of the cutter.

DETAILED DESCRIPTION

[0029] 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. The described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0030] The current fixture usually has only one datum surface, through which the fixture is installed on the surface grinder. Since the datum surface has been determined, the orientation of the entire fixture and the body of the V-shaped cutter fixed in the fixture is determined. It is inconvenient for the grinding tool of the surface grinder to process relatively inclined cutter back angles and cutter front angles along different directions on different planes.

[0031] For the above technical issues, refer to Figure 1 and Figure 2The present embodiment provides a V-shaped cutter multi-station rapid grinding and forming tool, comprising a multi-angle positioning body 2, a grinding groove 23 is respectively opened at the two side edges of the top of the multi-angle positioning body 2, and a fixing groove 24 is opened at the end of the multi-angle positioning body 2 and at the position corresponding to the grinding groove 23. The size of the transverse section of the fixing groove 24 is larger than the size of the transverse section of the grinding groove 23. Before grinding the V-shaped cutter, the V-shaped cutter is first fixed in the fixing groove 24 with a locking screw 4.

[0032] Reference Figure 1 , Figure 7 and Figure 8 A grinding front angle reference surface 22 is formed vertically along the longitudinal direction at one end of the multi-angle positioning body 2. When it is necessary to machine the cutter front angle 32 on the V-shaped cutter 3, the multi-angle positioning body 2 is installed on the surface grinder workbench 12 with the grinding front angle reference surface 22 as the reference surface, so that the surface grinder can machine the cutter front angle 32 on the V-shaped cutter 3.

[0033] Reference Figure 3 and Figure 4 After the lower structure of the multi-angle positioning body 2 is cut off longitudinally at the connection between the grinding front angle reference surface 22 and the adjacent side surface, a grinding rear angle positioning surface 21 is formed, and the grinding rear angle positioning surface 21 is inclined relative to the grinding front angle reference surface 22.

[0034] A grinding rear angle reference surface 25 is formed along an inclined direction at an upper portion of one end of the multi-angle positioning body 2 opposite to the grinding front angle reference surface 22 .

[0035] The multi-angle positioning body 2 is installed on a surface grinder with the grinding rear angle positioning surface 21 as a reference surface, and the V-shaped cutter 3 is installed on the grinding rear angle reference surface 25 to facilitate the surface grinder to process the cutter rear angle 31 on the V-shaped cutter 3.

[0036] The multi-angle positioning body 2 is mounted on a surface grinder with the grinding front angle reference plane 22 as the reference plane, so that the grinding wheel 11 is conveniently aligned with the V-groove of the V-shaped cutter 3, and the cutter front angle 32 is ground at one side edge of the V-groove of the V-shaped cutter 3.

[0037] The cutter back angle 31 is inclined relative to the cutter front angle 32. The multi-angle positioning body 2 is mounted on a surface grinder with the grinding back angle positioning surface 21 as a reference surface, so that the grinding wheel 11 is conveniently aligned with the V-shaped groove of the V-shaped cutter 3, and the cutter back angle 31 is ground at the other side edge of the V-shaped groove of the V-shaped cutter 3.

[0038] The grinding rear angle positioning surface 21 is inclined relative to the grinding front angle reference surface 22. By selecting the grinding rear angle positioning surface 21 or the grinding front angle reference surface 22 as the installation reference surface, the orientation of the V-shaped groove on the V-shaped cutter 3 can be conveniently adjusted by the forming tool, so as to facilitate grinding on the V-shaped groove to form the cutter front angle 32 and the cutter rear angle 31.

[0039] Reference Figure 4 A ground angle positioning surface 21 is formed on both sides of the lower part of the multi-angle positioning body 2, and the ground angle positioning surface 21 is located directly below the grinding groove 23.

[0040] Reference Figure 2 The V-shaped cutter 3 includes a cutter body 33, and a V-shaped groove is formed at the top of the cutter body 33. On both sides of the V-shaped groove, a cutter front angle 32 is formed at one edge of the side surface, and a cutter back angle 31 is formed at the other edge of the side surface. The cutter front angle 32 is inclined relative to the cutter back angle 31.

[0041] Reference Figure 4 , the orientation of the outlet of the fixing groove 24 is inclined relative to the height direction of the multi-angle positioning body 2. After the V-shaped cutter 3 is fixed in the fixing groove 24, the orientation of the V-shaped groove of the V-shaped cutter 3 is inclined relative to the height direction of the multi-angle positioning body 2, and the side of the V-shaped groove faces the grinding wheel 11 of the surface grinder 1. By setting the V-shaped cutter 3 to be inclined relative to the vertical direction and adjusting the orientation of the side of the V-shaped groove, it is convenient for the grinding wheel 11 to grind the side of the V-shaped groove to obtain the cutter front angle 32 and the cutter back angle 31.

[0042] Reference Figure 5 After the V-shaped cutter 3 is installed in the fixing groove 24, the angle a between the length direction of the V-shaped cutter 3 and the height direction of the multi-angle positioning body 2 is greater than or equal to 30 degrees and less than or equal to 55 degrees. In this embodiment, the angle a between the length direction of the V-shaped cutter 3 and the height direction of the multi-angle positioning body 2 is set to 42.83 degrees.

[0043] Reference Figure 6 , the angle b between the ground angle reference surface 25 and the height direction of the multi-angle positioning body 2 is greater than or equal to 120 degrees and less than or equal to 175 degrees. In this embodiment, the angle b between the ground angle reference surface 25 and the height direction of the multi-angle positioning body 2 is 166.5 degrees.

[0044] Working principle:

[0045] The multi-angle positioning body 2 is mounted on a surface grinder with the grinding front angle reference plane 22 as the reference plane, so that the grinding wheel 11 is conveniently aligned with the V-groove of the V-shaped cutter 3, and the cutter front angle 32 is ground at one side edge of the V-groove of the V-shaped cutter 3.

[0046] The cutter back angle 31 is inclined relative to the cutter front angle 32. The multi-angle positioning body 2 is mounted on a surface grinder with the grinding back angle positioning surface 21 as a reference surface, so that the grinding wheel 11 is conveniently aligned with the V-shaped groove of the V-shaped cutter 3, and the cutter back angle 31 is ground at the other side edge of the V-shaped groove of the V-shaped cutter 3.

[0047] The grinding rear angle positioning surface 21 is inclined relative to the grinding front angle reference surface 22. By selecting the grinding rear angle positioning surface 21 or the grinding front angle reference surface 22 as the installation reference surface, the orientation of the V-shaped groove on the V-shaped cutter 3 can be conveniently adjusted by the forming tool, so as to facilitate grinding on the V-shaped groove to form the cutter front angle 32 and the cutter rear angle 31.

[0048] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
