Description

Technical Field

[0001] This utility model relates to the field of plunge milling tool technology, specifically a novel plunge milling tool. Background Technology

[0002] A key characteristic of plunge milling is that the tool feeds axially, resulting in low radial cutting force and a large allowable tool overhang, making it ideal for machining deep cavities, deep grooves, and thin-walled parts. In actual production, plunge milling can significantly improve machining efficiency when machining mold cavities, integral impellers, and integral impeller disks, thus demonstrating its broad application prospects.

[0003] Most existing plunge milling cutters are one-piece designs. When the cutter head is damaged, the entire cutter needs to be replaced, which increases costs. Therefore, this utility model provides a new type of plunge milling cutter. Utility Model Content

[0004] The purpose of this utility model is to provide a new type of plunge milling cutter, which has the advantage of being able to replace the cutter head separately. This solves the problem that most existing plunge milling cutters are one-piece, and when the cutter head is damaged, the entire cutter needs to be replaced, which increases costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A novel milling cutter includes a cutter body and a cutter head. The cutter head is connected to the left end of the cutter body, and a slot is provided at the right end of the cutter head. A plug block adapted to the slot is provided at the left end of the cutter body. Limiting blocks are symmetrically arranged on the outer wall of the plug block. A guide groove adapted to the limiting block is provided in the slot. A limiting fixing groove is provided in the slot. The limiting fixing groove, the guide groove, and the slot are connected. A groove is provided on the right side of the limiting block. A spring is fixedly connected in the groove. A fixing block is connected to the right end of the spring. A retaining groove is provided at the right end of the limiting fixing groove. The fixing block is inserted into the retaining groove. The retaining groove is connected to a through hole, which extends to the outer end of the cutter head.

[0006] Preferably, the fixing block and the groove are slidably connected.

[0007] Preferably, the end of the fixing block away from the spring is spherical.

[0008] Preferably, a rod is inserted into the through hole, and the end of the rod near the slot has an inclined surface.

[0009] Preferably, the blade, the insert block, and the limiting block are integrally formed.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. The cutter body and cutter head of this utility model are separate and can be disassembled. When the cutter head is damaged, it can be replaced separately, thereby reducing costs and reducing unnecessary material waste.

[0012] 2. By setting the guide groove, the blade body and the blade head are positioned and inserted. Then, the rotation causes the limiting block to enter the limiting fixing groove. When the limiting fixing groove is rotated to its limit position, the fixing block is inserted into the slot under the action of the spring force, thereby stabilizing the blade body and the blade head.

[0021] Please see Figures 1 to 4 This utility model provides an embodiment of a novel milling cutter, comprising a cutter body 1 and a cutter head 2. The cutter head 2 is connected to the left end of the cutter body 1, and a slot 3 is formed at the right end of the cutter head 2. A plug 4 adapted to the slot 3 is provided at the left end of the cutter body 1. The plug 4 is inserted into the slot 3. Limiting blocks 6 are symmetrically arranged on the outer wall of the plug 4. A guide groove 11 adapted to the limiting block 6 is formed in the slot 3. A limiting fixing groove 5 is formed in the slot 3. The limiting fixing groove 5, the guide groove 11, and the slot 3 are connected. The right side of the limiting block 6 has a groove 7, and a spring 8 is fixedly connected in the groove 7. The right end of the spring 8 is connected to a fixing block 9. The right end of the limiting fixing groove 5 has a slot 12. When the limiting block 6 rotates to the limit position of the limiting fixing groove 5, the fixing block 9 is inserted into the slot 12 under the elastic force of the spring 8, so that the blade body 1 and the blade head 2 are stably fixed. The slot 12 is connected to a through hole 10, which extends to the outer end of the blade head 2 for disassembling the blade body 1 and the blade head 2.

[0022] The fixing block 9 and the groove 7 are slidably connected.

[0023] The end of the fixing block 9 away from the spring 8 is spherical, which makes it easy for the fixing block 9 to be fully inserted into the groove 7 after being pressed.

[0024] A rod 13 is inserted into the through hole 10. The end of the rod 13 near the slot 12 has a bevel. After the rod 13 is inserted into the through hole 10, it is easy to squeeze the fixing block 9 and make the fixing block 9 enter the groove 7, so that the blade body 1 and the blade head 2 can be disassembled.

[0025] The blade 1, insert block 4, and limit block 6 are integrally formed.

[0026] Working principle: The cutter body 1 and cutter head 2 of this utility model are separate and can be disassembled.
