[0004] Based on the above search, the following problems exist in the use of the above patent: Although the double-head forming slot milling cutter has two tool tips that can be used, effectively reducing the tool replacement cost and inventory space, when both tool tips are damaged, the staff needs to replace both tool tips and the tool shank, and the tool tips cannot be replaced separately. Since the tool shank is not damaged, replacing the tool tips and the tool shank as a whole causes waste and economic losses, increasing the tool replacement cost. Summary of the Utility Model

[0005] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art, and provide a double-head alloy tool, which can solve the problem that the tool tips cannot be replaced separately. Since the tool shank is not damaged, replacing the tool tips and the tool shank as a whole causes waste and economic losses, increasing the tool replacement cost.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A double-head alloy tool includes an alloy tool shank. Circular mounting grooves are opened at both the upper and lower ends of the alloy tool shank. Mounting cylindrical rods are slidably mounted inside the two circular mounting grooves. Alloy tool tips are fixedly connected to the opposite ends of the two mounting cylindrical rods. Two cutting edges are opened on the surfaces of the two alloy tool tips. Fixing devices are provided on the inner walls of the two circular mounting grooves.

[0007] Preferably, the fixing device includes two fixing key blocks, which are respectively fixedly connected to the inner walls of the two circular mounting grooves. Fixing key grooves are opened on the surfaces of the two mounting cylindrical rods. The two fixing key blocks are respectively slidably connected inside the two fixing key grooves.

[0008] Preferably, two hexagon socket head cap screws are installed inside the alloy tool shank. Two placing round holes are formed on the surface of the alloy tool shank, and the nuts of the two hexagon socket head cap screws can be hidden inside the two placing round holes.

[0009] Preferably, fixing clamping holes are formed on the surfaces of the two mounting cylindrical rods, and the two hexagon socket head cap screws are respectively slidably clamped inside the two fixing clamping holes.

[0010] Preferably, annular clamping grooves are formed on the surfaces of the two alloy tool tips, and rubber sealing rings are fixedly connected inside the two annular clamping grooves.

[0011] Preferably, annular grooves are formed at the upper and lower ends of the alloy tool shank, and the two rubber sealing rings are respectively slidably clamped inside the two annular grooves.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. For this double-head alloy cutting tool, the staff can rotate the hexagon socket head cap screw again through a wrench. When the hexagon socket head cap screw rotates and is clamped inside the fixing clamping hole again, the mounting cylindrical rod can be fixedly installed inside the alloy tool shank, and then the alloy tool tip can be fixedly installed at the top of the alloy tool shank. At this time, the staff can replace the alloy tool tip separately. Since the alloy tool shank is not damaged, the alloy tool shank does not need to be replaced, thus avoiding waste of the alloy tool shank, reducing economic losses, and reducing the cost of tool replacement.

[0024] In the description of the present utility model, unless otherwise clearly defined, words such as "set", "installed", "connected", etc. should be understood in a broad sense. 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.

[0025] Please refer to Figures 1-5, the present utility model provides a technical solution: a double - headed alloy tool, including an alloy tool rod 1. Circular mounting grooves 2 are opened at both the upper and lower ends of the alloy tool rod 1. Mounting cylindrical rods 3 are slidably mounted inside the two circular mounting grooves 2. Alloy tool heads 4 are fixedly connected to the opposite ends of the two mounting cylindrical rods 3. Two cutting edges 5 are opened on the surfaces of the two alloy tool heads 4. Fixed key blocks 6 are fixedly connected to the inner walls of the two circular mounting grooves 2. Fixed key grooves 7 are opened on the surfaces of the two mounting cylindrical rods 3. The two fixed key blocks 6 are respectively slidably connected inside the two fixed key grooves 7. Two hexagon socket head cap screws 8 are installed inside the alloy tool rod 1. Placing circular holes 9 are opened on the surface of the alloy tool rod 1. The nuts of the two hexagon socket head cap screws 8 can be hidden inside the two placing circular holes 9. Fixed clamping holes 10 are opened on the surfaces of the two mounting cylindrical rods 3. The two hexagon socket head cap screws 8 are respectively slidably clamped inside the two fixed clamping holes 10.

[0026] When using this double - headed alloy tool, the staff can hold the alloy tool rod 1 through the tool handle. By fixing the alloy tool rod 1 in this way, when one of the alloy tool heads 4 is damaged, the staff can reverse the up - down position of the alloy tool rod 1, and then can use the two alloy tool heads 4. When both alloy tool heads 4 are damaged, the staff can replace the two alloy tool heads 4 separately. The staff rotates the hexagon socket head cap screw 8 with a wrench. The hexagon socket head cap screw 8 rotates and gradually moves outward and disengages from the inside of the fixed clamping hole 10 through the threaded connection with the alloy tool rod 1, thus releasing the fixing effect on the mounting cylindrical rod 3 and the alloy tool head 4. At this time, the staff slides the alloy tool head 4 upward and drives the mounting cylindrical rod 3 to slide out of the inside of the circular mounting groove 2 to complete the disassembly. Then, the staff takes out a new alloy tool head 4 and drives the mounting cylindrical rod 3 to slide downward into the inside of the circular mounting groove 2. At this time, the fixed key block 6 snaps into the fixed key groove 7. The connection between the fixed key block 6 and the fixed key groove 7 can ensure the stability of the connection between the mounting cylindrical rod 3, the alloy tool head 4 and the alloy tool rod 1. The staff rotates the hexagon socket head cap screw 8 with a wrench again, and the hexagon socket head cap screw 8 rotates and snaps into the inside of the fixed clamping hole 10 again to fixedly install the mounting cylindrical rod 3 inside the alloy tool rod 1, and then fixedly install the alloy tool head 4 at the top of the alloy tool rod 1. At this time, the staff can replace the alloy tool head 4 separately. Since the alloy tool rod 1 is not damaged, the alloy tool rod 1 does not need to be replaced, thus avoiding waste of the alloy tool rod 1, reducing economic losses and decreasing the cost of tool replacement.

[0027] An annular clamping groove 11 is formed on the surface of each of the two alloy tool bits 4. A rubber sealing ring 12 is fixedly connected to the inside of each of the two annular clamping grooves 11. Annular grooves 13 are formed at the upper and lower ends of the alloy tool bar 1. The two rubber sealing rings 12 are respectively slidably clamped inside the two annular grooves 13.

[0028] After the alloy tool bit 4 is installed on the top of the alloy tool bar 1, the alloy tool bit 4 drives the rubber sealing ring 12 to slide downward and squeeze into the inside of the annular groove 13. Then, the sealing performance of the connection position between the alloy tool bit 4 and the alloy tool bar 1 is improved through the extrusion between the rubber sealing ring 12 and the annular groove 13, preventing the cutting fluid from entering the inside of the circular installation groove 2 and causing corrosion and damage, ensuring the safety of the alloy tool bar 1 during use, and thus extending the service life of the alloy tool bar 1.

[0029] Working principle: For this double-headed alloy tool, the operator rotates the hexagon socket head cap screw 8 with a wrench. The hexagon socket head cap screw 8 rotates and gradually moves outward and disengages from the inside of the fixed clamping hole 10 through the threaded connection with the alloy tool bar 1, thereby releasing the fixing effect on the installation cylindrical rod 3 and the alloy tool bit 4. At this time, the operator slides the alloy tool bit 4 upward and drives the installation cylindrical rod 3 to slide out of the inside of the circular installation groove 2 to complete the disassembly. Then, the operator takes out a new alloy tool bit 4 and drives the installation cylindrical rod 3 to slide downward into the inside of the circular installation groove 2. At this time, the fixed key block 6 snaps into the fixed key groove 7. The operator rotates the hexagon socket head cap screw 8 with a wrench again, and the hexagon socket head cap screw 8 rotates and snaps into the inside of the fixed clamping hole 10 again to fixedly install the alloy tool bit 4 on the top of the alloy tool bar 1. At this time, the operator can replace the alloy tool bit 4 separately. The alloy tool bit 4 drives the rubber sealing ring 12 to slide downward and squeeze into the inside of the annular groove 13. Then, the sealing performance of the connection position between the alloy tool bit 4 and the alloy tool bar 1 is improved through the extrusion between the rubber sealing ring 12 and the annular groove 13, preventing the cutting fluid from entering the inside of the circular installation groove 2 and causing corrosion and damage.

[0030] The above has described the embodiments of the present invention in detail with reference to the drawings. However, the present invention is not limited to the above embodiments. Various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those of ordinary skill in the art.
