[0003] The currently published patent: CN218532845U discloses an alloy cutting tool that is easy to replace the tool head. Through the design of the installation structure, firstly, the limiting protrusion supports the limiting installation ring, and cooperates with the tool jack to preliminarily limit and fix the tool. At the same time, with the cooperation of two sealing rings, the butt joint of the limiting installation ring is more closely fitted. Finally, the overall installation and fixation are completed through the threaded connection between the threaded installation groove and the installation ring. The overall process is simple and convenient, making the tool installation more stable without affecting the overall structure, and maintaining the original processing effect during operation.

[0004] Based on the above search, the following problems exist in the use of the above patent: When the alloy cutting tool that is easy to replace the tool head is in use, firstly, the limiting protrusion supports the limiting installation ring, and cooperates with the tool jack to preliminarily limit and fix the tool. At the same time, with the cooperation of two sealing rings, the butt joint of the limiting installation ring is more closely fitted. However, the fixing strength of the tool head only through the limiting installation ring is small, and the stability of the tool head in the tool is poor.

Those skilled in the art can reasonably determine the specific meanings of the above words in the present utility model in combination with the specific content of the technical solution.

[0024] Please refer to Figures 1-4The utility model provides a technical solution: an alloy tool with a replaceable cutter head, comprising an alloy tool 1 and a fixing device, a circular mounting hole 2 is provided at the bottom of the alloy tool 1, an alloy tool head 3 is slidably installed inside the circular mounting hole 2, four cutting edges 4 are provided on the surface of the alloy tool head 3, four positioning card slots 5 are provided in a circular shape and equidistantly at the top of the alloy tool head 3, the fixing device comprises four positioning card blocks 6, a fixing key block 8 and a hexagon socket bolt 9, the four positioning card blocks 6 are fixedly connected to the top wall of the circular mounting hole 2 in a circular shape and equidistantly at the top, and the four positioning card slots 5 are provided in a circular shape and equidistantly at the top. Blocks 6 are respectively slidably connected to the inside of the four positioning slots 5, a square slot 7 is opened inside the alloy tool 1, and the fixed key block 8 is slidably connected to the inside of the square slot 7. The hexagon socket bolt 9 is rotatably installed inside the alloy tool 1, and the left end of the hexagon socket bolt 9 is threadedly connected to the inside of the fixed key block 8. A circular placement hole 10 is opened on the surface of the alloy tool 1, and the nut at the right end of the hexagon socket bolt 9 is placed inside the circular placement hole 10. A fixed key slot 11 is opened on the surface of the alloy cutter head 3, and the fixed key block 8 is slidably connected to the inside of the fixed key slot 11.

[0025] When installing the alloy tool, the staff only needs to pick up an alloy tool head 3 and slide it into the inside of the circular mounting hole 2, and rotate the sliding alloy tool head 3 so that the four positioning blocks 6 slide into the inside of the four positioning slots 5 respectively. The clamping action between the four positioning slots 5 and the four positioning blocks 6 can not only enhance the stability of the connection between the alloy tool 1 and the alloy tool head 3, but also make the fixed key slot 11 face the position of the fixed key block 8. At this time, the staff rotates the hexagon socket bolt 9 with a wrench, and the hexagon socket bolt 9 rotates and drives the fixed key block 8 to move through the threaded connection between the fixed key block 8, and makes the fixed key block 8 move to the inside of the fixed key slot 11 to complete the installation of the alloy tool head 3. Fixing effect, at this time, the alloy cutter head 3 can be fixedly installed inside the alloy tool 1. When the alloy cutter head 3 needs to be replaced, the staff only needs to use a wrench to reversely rotate the hexagon socket bolt 9 and drive the fixed key block 8 to move out of the fixed key slot 11. Then, the staff slides the alloy cutter head 3 downward and disengages it from the inside of the circular mounting hole 22 to complete the disassembly, which makes it convenient for the staff to disassemble and replace the alloy cutter head 3. The clamping effect between the four positioning slots 5 and the four positioning blocks 6 increases the strength of the connection between the alloy tool 1 and the alloy cutter head 3, and improves the stability of the alloy cutter head 3 in the alloy tool 1, so that the alloy cutter head 3 can withstand a stronger force, thereby improving the safety of the alloy tool.

[0026] After the hexagon socket head bolt 9 rotates and drives the fixed key block 8 to move into the fixed key groove 11 to complete the fixation of the alloy cutting head 3, at this time, the nut at the end of the hexagon socket head bolt 9 away from the fixed key block 8 is hidden inside the circular placement hole 10, thereby maintaining the flatness of the surface of the alloy tool 1, preventing protrusions from occurring on the surface of the alloy tool 1, and facilitating the use of the alloy tool during processing.

[0027] Working principle: For this alloy tool with replaceable cutting heads, during use, the operator only needs to pick up an alloy cutting head 3 and slide it into the circular mounting hole 2, and rotate and slide the alloy cutting head 3 so that the four positioning blocks 6 respectively slide into and engage with the four positioning slots 5. The engagement between the four positioning slots 5 and the four positioning blocks 6 can not only enhance the connection stability between the alloy tool 1 and the alloy cutting head 3, but also make the position of the fixed key groove 11 face the fixed key block 8. At this time, the operator rotates the hexagon socket head bolt 9 with a wrench. The hexagon socket head bolt 9 rotates and drives the fixed key block 8 to move through the threaded connection with the fixed key block 8, and makes the fixed key block 8 move into the fixed key groove 11 to complete the fixation of the alloy cutting head 3. At this time, the alloy cutting head 3 can be fixedly installed inside the alloy tool 1. The engagement between the four positioning slots 5 and the four positioning blocks 6 increases the connection strength between the alloy tool 1 and the alloy cutting head 3, improves the stability of the alloy cutting head 3 in the alloy tool 1, thereby enabling the alloy cutting head 3 to withstand stronger forces and enhancing the safety of using this alloy tool.

[0028] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the knowledge scope of those of ordinary skill in the art in the said technical field, various changes can be made without departing from the purpose of the present invention.
