Description
Technical Field
[0001] This utility model relates to the field of precision cutting tool technology, and in particular to a workpiece integral forming cutting tool with replaceable cutting heads. Background Technology
[0002] Replaceable-head workpiece integral forming tools are specialized tool structures designed for various workpiece integral forming machining scenarios. The core design concept is to disassemble the tool into two core components: the tool body and the tool head. The tool body is usually made of high-strength, high-rigidity alloy material and serves as the basic load-bearing structure of the tool. It can be adapted to the clamping and transmission systems of machine tools and has the characteristic of long-term reusability. The tool head is selected according to the material, forming accuracy, cutting parameters and other requirements of the workpiece. It is assembled to the mounting position at the front end of the tool body through connection methods such as thread, snap-fit, and welding auxiliary locking. In the prior art, when the tool holder of the replaceable tool head integral forming tool clamps and fixes the tool head connection part through the built-in clamping part, the connection stability between the tool head and the tool holder is insufficient because a point-to-point snap-fit positioning structure is not set. Therefore, we propose a replaceable tool head integral forming tool. Utility Model Content
[0003] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a workpiece integral forming tool with replaceable cutting head. By adding a docking groove on the cutting head body, it can form a point-to-point snap-fit positioning with the tool holder clamping part, which effectively improves the stability of the docking connection between the cutting head and the tool holder and avoids problems such as loosening and wobble of the cutting head during the processing.
[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A workpiece integral forming tool with replaceable cutting head, including a tool holder mechanism, a locking mechanism installed at the inner end of the tool holder mechanism, and a cutting head mechanism connected to the front end of the tool holder mechanism; The cutting head mechanism includes a cutting head body, a cutting edge at the front end of the cutting head body, and a connecting rod at the end of the cutting head body. The connecting rod and the outer end of the connector are provided with a mating groove. By adding a mating groove on the cutting head body, a point-to-point snap-fit positioning fit can be formed with the clamping part of the handle body, effectively improving the stability of the docking connection between the cutting head body and the handle body.
[0005] Furthermore, the locking mechanism includes an adjusting rod, an adjusting hole at the inner end of the adjusting rod, a contact rod at the front end of the adjusting rod, an adjusting arm at the front of the contact rod, a slot at the inner end of the adjusting arm, and an adjusting head at the front end of the adjusting rod. By adapting the adjusting hole to an external adjusting head for control and transmission, force is transmitted to the adjusting arm via the contact rod and precisely engaged through the slot, thereby achieving precise and convenient locking and unlocking adjustment of the cutter head body, improving the reliability of the connection between the cutter head body and the cutter handle body and the flexibility of disassembly and assembly.
[0006] Furthermore, the tool holder mechanism includes a tool holder body, a through hole at the end of the tool holder body, a connector at the front end of the tool holder body, a clamping arm fixedly mounted on the front side of the inner end of the tool holder body, a connecting groove at the middle of the inner end of the tool holder body, a bevel at the end of the connecting groove, and a locking block on the inner side of the clamping arm. By setting the locking block to engage with the mating groove, a precise point-to-point positioning fit can be formed, effectively enhancing the structural stability of the docking connection between the tool head body and the tool holder body.
[0007] Furthermore, the adjusting rod is movably installed at the inner end of the connecting groove. By movably installing the adjusting rod at the inner end of the connecting groove, the adjusting rod can flexibly complete axial or circumferential adjustment actions within the space defined by the connecting groove.
[0008] Furthermore, the connector is nested inside the clamping arm.
[0009] Furthermore, the position of the locking block corresponds to that of the docking groove, and the shape of the locking block is adapted to that of the docking groove.
[0010] Furthermore, the adjusting arm is movably mounted at the end of the connecting groove.
[0011] Furthermore, the contact rod is positioned corresponding to the slot, and the contact rod is movably nested inside the slot.
[0012] In summary, this utility model has the following beneficial effects: 1. By adding a docking groove on the cutter head body, a point-to-point snap-fit positioning fit can be formed with the clamping part of the cutter handle body, which effectively improves the stability of the docking connection between the cutter head body and the cutter handle body. By setting an adjustment hole to adapt to the external adjustment head control transmission, the force is transmitted to the adjustment arm through the contact rod and precisely snapped through the slot, realizing precise and convenient locking and unlocking adjustment of the cutter head body, improving the reliability of the connection between the cutter head body and the cutter handle body and the flexibility of disassembly and assembly. 2. By setting the locking blocks to engage with the docking slots, a precise point-to-point positioning fit can be formed, effectively enhancing the structural stability of the connection between the cutter head body and the cutter shank body. By movably installing the adjusting rod at the inner end of the connecting slot, the adjusting rod can flexibly complete axial or circumferential adjustment within the space defined by the connecting slot.

The mating joint 304 is nested in the inner end of the clamping arm 104. By adding the mating groove 305 to the cutting head body 301, a point-to-point snap-fit positioning fit can be formed with the clamping part of the tool holder body 101, which effectively improves the stability of the docking connection between the cutting head body 301 and the tool holder body 101 and avoids problems such as loosening or wobble of the cutting head body 301 during processing.
[0018] Reference Figure 1-3 As shown, the locking mechanism 2 includes an adjusting rod 201. An adjusting hole 202 is provided on the inner side of the end of the adjusting rod 201. A contact rod 203 is provided at the front end of the adjusting rod 201. An adjusting arm 204 is provided on the front side of the contact rod 203. A slot 205 is provided on the inner side of the end of the adjusting arm 204. An adjusting head 206 is provided at the front end of the adjusting rod 201. The adjusting arm 204 is movably installed at the end of the connecting groove 105. The contact rod 203 and the slot 205 are positioned correspondingly. The contact rod 203 is movably nested in the inner end of the slot 205. The adjustment hole 202 is adapted to the external adjusting head 206 for control and transmission. Force is transmitted to the adjusting arm 204 through the contact rod 203 and precisely engaged through the slot 205, realizing precise and convenient locking and unlocking adjustment of the cutter head body 301, improving the reliability of the connection between the cutter head body 301 and the cutter handle body 101 and the flexibility of disassembly and assembly.
[0019] Reference Figure 1-5 As shown, the tool holder mechanism 1 includes a tool holder body 101. A through hole 102 is provided at the end of the tool holder body 101. A connector 103 is provided at the front end of the tool holder body 101. A clamping arm 104 is fixedly provided on the front side of the inner end of the tool holder body 101.

The shape of the locking block 107 and the docking groove 305 are adapted to each other. By setting the locking block 107 to be correspondingly engaged with the docking groove 305, a point-to-point precise positioning fit can be formed, which effectively enhances the structural stability of the docking connection between the tool head body 301 and the tool holder body 101.
[0020] Reference Figure 2-5 As shown, the adjusting rod 201 is movably installed at the inner end of the connecting groove 105. By movably installing the adjusting rod 201 at the inner end of the connecting groove 105, the adjusting rod 201 can flexibly complete axial or circumferential adjustment actions within the space defined by the connecting groove 105.
[0021] Specific implementation process: During operation, the connector 304 is first nested into the inner end of the clamping arm 104, so that the inner locking block 107 of the clamping arm 104 and the mating groove 305 of the connector 304 are precisely engaged to form point-to-point positioning. Then, by using the adjustment hole 202 at the end of the external adjustment component to adapt to the adjustment component, the adjustment rod 201, which is movably installed in the inner end of the connecting groove 105, is operated to make axial and circumferential adjustments. The force is transmitted to the adjustment arm 204 through the front contact rod 203, and the contact rod 203 is nested into the locking groove 205 of the adjustment arm 204, thereby pushing the adjustment arm 204 to slide along the inclined surface 106, and the clamping arm 104 is pressed downward by the adjustment head 206. Locking is achieved; during processing, the engagement of the locking block 107 with the docking groove 305 and the constraint of the connecting groove 105 on the adjusting rod 201 ensure stable connection between the cutter head body 301 and the cutter shank body 101, and the cutting edge 302 can stably complete the integral forming processing of the workpiece; when the cutter head needs to be replaced, the adjusting hole 202 is reversed to drive the adjusting rod 201 to move inward, pushing the cutter head body 301, causing the adjusting head 206 to return along the inclined surface 106, causing the contact rod 203 to disengage from the locking groove 205 to release the lock, and the cutter head body 301 is pulled out to separate the locking block 107 from the docking groove 305. After replacing the new cutter head mechanism 3, the above assembly and locking steps can be repeated.
