[0001] This utility model relates to the field of turbocharger volute machining technology, specifically a turning tool for turbocharger volute lathe. Background Technology

[0002] Turbocharger volute machining revolves around high-strength material forming, precision control of complex flow channels, and ensuring sealing and heat resistance. It is a key component that is adapted to turbochargers. The core objective is to ensure the aerodynamic efficiency of the volute flow channel, the precision of the flange sealing, and the stability under high-temperature conditions, which directly affects the turbocharger's boost efficiency and service life, and is suitable for power systems in automobiles, construction machinery, and ships.

[0003] In existing technologies, the surface or inner wall of a turbocharger volute requires turning during machining. The shape and quality of the turning tool directly affect the subsequent machining quality of the volute. Furthermore, if the turning tool is subjected to impact or vibration and shifts during use, and this shift is not detected in time, it will affect the smoothness of the machining process. Therefore, this application designs a turning tool for a turbocharger volute lathe. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a turning tool for a turbocharger volute lathe to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution.

[0006] This utility model provides a turning tool for a turbocharger volute lathe, including a tool holder, a tool head at the end of the tool holder, a notch in the inner wall of the tool head, a threaded hole in the inner wall of the notch, a cutting edge in the inner wall of the notch, a threaded bolt connecting the cutting edge and the tool head, a cavity inside the tool head, a first metal elastic strip fixedly connected to the inner wall of the cavity, a pressure block fixedly connected to the end of the first metal elastic strip, a push rod fixedly connected to the side of the pressure block opposite to the first metal elastic strip, and a top block fixedly connected to the end of the push rod away from the pressure block.

[0007] Preferably, the cutting head is slidably provided with a transmission block on the inner wall of the cavity, the top block is pressed against the transmission block, and the corresponding sides of the top block and the transmission block are respectively set as inclined surfaces.

[0008] Preferably, a warning plate is fixedly connected to one end of the transmission block away from the top block. The warning plate is slidably disposed on the inner wall of the cavity. An opening is provided on the side wall of the cutter head, and the warning plate extends through the opening to the outer side of the cutter head.

[0009] Preferably, a fluorescent strip is fixedly connected to the side wall of the warning board.

[0010] Preferably, the cutter head has a guide groove on the inner wall of the cavity, and a guide block is fixedly connected to the side wall of the pressure block, and the guide block is slidably disposed on the inner wall of the guide groove.

[0011] Preferably, the cutter head is fixedly connected to a stop block on the inner wall of the opening, and a second metal elastic strip is fixedly connected to the side wall of the stop block, with the end of the second metal elastic strip fixedly connected to the end of the transmission block.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. The turning tool for the turbocharger volute lathe, when the cutting edge wears to a certain extent, the increased cutting force will push the pressure block to further compress the first metal elastic strip, causing the pressure block to drive the push rod to move into the cavity of the tool head. The top block at the end of the push rod and the corresponding side of the transmission block are both inclined. When the top block moves, it pushes the transmission block to slide towards the opening of the side wall of the tool head through the inclined surface. The warning plate fixedly connected to the end of the transmission block away from the top block moves synchronously with the transmission block, extending through the opening of the tool head to the outside of the tool head, visually indicating to the operator that the cutting edge has reached the wear level that needs to be replaced.

[0013] 2. The turning tool for the turbocharger volute lathe achieves a firm connection between the cutting edge and the tool head by passing a mounting bolt through the threaded hole in the inner wall of the tool head recess. This detachable connection method facilitates the replacement of cutting edges of different specifications or materials according to the machining requirements of the turbocharger volute, improving the versatility of the tool. After assembly, the first metal elastic strip in the tool head cavity is in a naturally extended state, and the pressure block fixed at its end fits against the side wall of the cutting edge under the action of elasticity, further pressing and limiting the cutting edge to prevent the cutting edge from undergoing slight displacement due to vibration during turning, thus ensuring turning accuracy.

[0014] 3. The turning tool for the turbocharger volute lathe, during the movement of the transmission block, compresses the second metal elastic strip on the stop block fixed to the inner wall of the tool head opening, storing elastic potential energy. When a new cutting edge is replaced, the cutting resistance returns to normal, the first metal elastic strip pushes the pressure block and push rod to reset, the pushing force of the top block on the transmission block disappears, the second metal elastic strip releases elastic potential energy, pushing the transmission block and warning plate back to the initial position, waiting for the next wear monitoring, thus realizing the cyclic use of the warning function.

[0017] A turning tool for a turbocharger volute lathe, such as Figure 1-4 The tool includes a handle 1, a blade head 2 at the end of the handle 1, a notch in the inner wall of the blade head 2, a threaded hole in the inner wall of the notch, a cutting edge 4 in the inner wall of the notch, a bolt 3 threadedly connected to the blade 4 and the blade head 2, a cavity inside the blade head 2, a first metal elastic strip 5 fixedly connected to the inner wall of the cavity, a pressure block 6 fixedly connected to the end of the first metal elastic strip 5, a push rod 7 fixedly connected to the side of the pressure block 6 opposite to the first metal elastic strip 5, and a top block 8 fixedly connected to the end of the push rod 7 away from the pressure block 6.

[0018] The cutter head 2 is slidably provided with a transmission block 9 on the inner wall of the cavity. The top block 8 is pressed against the transmission block 9. The corresponding sides of the top block 8 and the transmission block 9 are respectively set as inclined surfaces. A warning plate 10 is fixedly connected to the end of the transmission block 9 away from the top block 8. The warning plate 10 is slidably provided on the inner wall of the cavity. An opening is opened on the side wall of the cutter head 2. The warning plate 10 extends through the opening to the outside of the cutter head 2. A fluorescent strip 11 is fixedly connected to the side wall of the warning plate 10.

[0019] In summary: The tool holder 1 secures the entire tool to the lathe turret or tool post, providing stable support for turning operations and adapting to the turning requirements of the complex curved surface of the turbocharger volute. The notch at the end of the tool head 2 provides installation and positioning space for the cutting edge 4. After the cutting edge 4 is placed against the inner wall of the notch, the mounting bolt 3 passes through the mounting threaded hole between the cutting edge 4 and the inner wall of the notch of the tool head 2, achieving a firm connection between the cutting edge 4 and the tool head 2. This detachable connection method facilitates the replacement of cutting edges 4 of different specifications or materials according to the machining requirements of the turbocharger volute, improving the versatility of the tool. After assembly, the first metal elastic strip 5 in the cavity of the tool head 2 is in a naturally extended state, and the pressure block 6 fixed at its end adheres to the side wall of the cutting edge 4 under the action of elasticity, further pressing and limiting the cutting edge 4 to prevent the cutting edge 4 from undergoing slight displacement due to vibration during turning, thus ensuring turning accuracy.

[0020] As the turning operation continues, the cutting edge 4 will gradually wear down, its cutting ability will decrease, and the cutting resistance will increase. When the cutting edge 4 wears to a certain extent, the increased cutting force will push the pressure block 6 to further compress the first metal elastic strip 5, causing the pressure block 6 to drive the push rod 7 to move into the cavity of the cutter head 2. The top block 8 at the end of the push rod 7 and the corresponding side of the transmission block 9 are both inclined. When the top block 8 moves, it pushes the transmission block 9 to slide towards the opening of the side wall of the cutter head 2 through the inclined surface. The warning plate 10, which is fixedly connected to the end of the transmission block 9 away from the top block 8, moves synchronously with the transmission block 9, extends through the opening of the cutter head 2 to the outside of the cutter head 2, and visually reminds the operator that the cutting edge 4 has reached the wear level that requires replacement. The fluorescent strip 11 on the side wall of the warning plate 10 can emit bright light in the dark processing environment, further improving the warning effect and preventing the operator from failing to detect the cutting edge wear in time, resulting in a decrease in processing quality or damage to the tool.

[0021] In summary, the tool ensures the assembly stability of the cutting edge 4 through the dual fixing effect of the mounting bolt 3 and the first metal elastic strip 5, ensures the turning accuracy through the rigid structure of the tool holder 1 and the cutting head 2, and realizes automatic monitoring and intuitive warning of cutting edge wear through the linkage mechanism composed of the first metal elastic strip 5, the top block 8, the transmission block 9 and the warning plate 10. The coordinated cooperation of all components effectively improves the turning efficiency and quality of the turbocharger volute.

[0022] To enable the cyclical use of the alert function, such as Figure 1-4 As shown, the cutter head 2 has a guide groove on the inner wall of the cavity, and a guide block 12 is fixedly connected to the side wall of the pressure block 6. The guide block 12 is slidably disposed on the inner wall of the guide groove. A stop block 13 is fixedly connected to the inner wall of the opening of the cutter head 2. A second metal elastic strip 14 is fixedly connected to the side wall of the stop block 13. The end of the second metal elastic strip 14 is fixedly connected to the end of the transmission block 9.

[0023] The guide block 12 on the side wall of the pressure block 6 is slidably set in the guide groove on the inner wall of the cavity of the cutter head 2, providing precise guidance for the movement of the pressure block 6, ensuring that the pressure of the pressure block 6 on the blade 4 is uniform and stable, and avoiding the pressure block 6 from deviating and causing the limit failure. During the movement of the transmission block 9, the second metal elastic strip 14 on the stop block 13 fixed on the inner wall of the opening of the cutter head 2 is compressed and stores elastic potential energy. When a new blade 4 is replaced, the cutting resistance returns to normal, the first metal elastic strip 5 pushes the pressure block 6 and the push rod 7 to reset, the pushing force of the top block 8 on the transmission block 9 disappears, the second metal elastic strip 14 releases elastic potential energy, and pushes the transmission block 9 and the warning plate 10 back to the initial position, waiting for the next wear monitoring, realizing the cyclic use of the warning function. The stop block 13 at the same time limits the movement range of the transmission block 9 to prevent the transmission block 9 from moving excessively and causing structural damage, ensuring the stable operation of the warning mechanism.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
