[0002] The alloy gear shaping cutter with negative chamfer along the edge is a gear shaping cutter made of high-performance alloy material. The gear shaping cutter is a commonly used tool in gear processing and is used to cut tooth shapes on gear blanks. The negative chamfer along the edge means that the cutting edge of the tool has a negative chamfer inclined toward the inside of the gear, which can improve the cutting efficiency and the processing quality of the gear. Compared with ordinary carbon steel materials, alloy materials have higher hardness and wear resistance, which makes the tool life longer and the cutting efficiency higher.

[0003] A gear shaping cutter generally consists of a cutter disc and cutter teeth, and the cutter teeth are obliquely distributed on the side surface of the cutter disc. However, the existing cutter disc and cutter teeth are all integrated in design. When one of the cutter teeth is worn, the entire gear shaping cutter needs to be replaced, resulting in a high replacement cost for the gear shaping cutter. Utility Model Content

The inner cavity of the groove 8 is connected to the inner cavity of the hollow cylinder 9. The opening size of the groove 8 is larger than the opening size of the hollow cylinder 9. Two rectangular holes 10 are provided on the surface of the tube 9, the spring piece 6 is in close contact with the outer surface of the hollow tube 9, the protruding part of the block 7 is located on the inner side of the rectangular hole 10, the surface of the block 7 is an inclined surface, a plug-in block 11 is fixedly installed on one side surface of the tooth 2, and a slot 12 is provided on the opposite side surface of the plug-in block 11, the block 7 is adapted to the slot 12, so that the block 7 can be easily inserted into the slot 12, the external shape and size of the plug-in block 11 are adapted to the internal shape and size of the hollow tube 9, and the shape and size of one end of the tooth 2 on the same side as the plug-in block 11 are adapted to the internal shape and size of the groove 8, so that the tooth 2 can be easily inserted into the groove 8, and the plug-in block 11 can be easily inserted into the hollow tube 9.

[0021] A limiting mechanism for limiting the mounting plate 5 is provided between the mounting plate 5 and the mounting cavity 3. The limiting mechanism includes a limiting groove 13 opened on the opposite side surface of the mounting cavity 3, and a limiting block 14 inserted into the limiting groove 13 is fixedly installed on the opposite side surface of the mounting plate 5, which helps to prevent the mounting plate 5 from tilting when moving.

[0022] It should be noted that a shifting block penetrating the outer surface of the cutter disc 1 is fixedly mounted on the surface of the mounting plate 5 in this embodiment, and the mounting plate 5 can be moved in the mounting cavity 3 by the shifting block.

[0023] It should be noted that the end of the plug-in block 11 in this embodiment away from the blade teeth 2 is an inclined surface.

[0024] The working principle of the above embodiment is:

[0025] When in use, the blade tooth 2 is inserted into the groove 8, so that the plug-in block 11 is inserted into the hollow cylinder 9, and the block 7 is squeezed to both sides by the plug-in block 11 until the slot 12 corresponds to the block 7, and the block 7 is inserted into the slot 12 by the spring piece 6, so that the plug-in block 11 can be fixed in the hollow cylinder 9, and the blade tooth 2 can be fixed on the cutter disc 1. When it is necessary to remove the blade tooth 2, the mounting plate 5 is moved toward the side close to the hollow cylinder 9 by the shifting block, and the spring 4 is compressed at this time. Since only a part of the block 7 is located in the rectangular hole 10 and the surface of one side of the block 7 is an inclined surface, when the mounting plate 5 is pushed, the spring piece 6 and the block 7 follow the mounting plate 5 to move, so that the block 7 slides out to the rectangular hole 10. At this time, the block 7 is separated from the slot 12, and then the plug-in block 11 can be taken out of the hollow cylinder 9. After releasing the shifting block, the mounting plate 5 is restored to its original position under the resetting action of the spring 4, and the protruding part of the block 7 is innovatively inserted into the rectangular hole 10.
