[0003] Traditional machining methods mainly rely on manual tool changing. After completing a certain process, the operator needs to manually loosen the current tool, disassemble and replace it with the tool required for the next process, and then re-set, position and clamp the tool. The whole tool changing process is not only cumbersome to operate, but also time-consuming. Utility Model Content

The turning tool is fixedly mounted on the turning machine tool. The turning tool includes a bracket fixedly mounted on the turning machine tool, a rotary changing unit for changing different turning tools, and two locking units for fixing the changed turning tool. The rotary changing unit is mounted on the bracket, and the two locking units are also mounted on the bracket and are linked with the rotary changing unit to apply a locking force after the turning tool is rotated into position to ensure that the turning tool is stably positioned.

[0005] Preferably, the rotating replacement unit includes a rotating shaft, a tool holder, a lathe tool, and two positioning discs. The rotating shaft is rotatably connected to the left and right sides of the bracket. The tool holder is fixedly mounted on the rotating shaft.

[0006] Preferably, the locking unit includes a supporting shell, two linear guide rods, a sliding plate, a spring, a pull rod, and a set of positioning rods. The supporting shell is fixedly disposed on the outer right side of the bracket. The two linear guide rods are fixedly disposed between the outer right side of the bracket and the inner right side of the supporting shell. The sliding plate is slidably connected to the two linear guide rods. The spring is fixedly disposed between the outer right side of the sliding plate and the inner right side of the supporting shell. The pull rod moves through the right side of the supporting shell, and one end of the pull rod is fixedly connected to the right side of the sliding plate. The pull rod is located inside the spring. A set of positioning rods is fixedly disposed on the left side of the sliding plate and moves through the right side of the bracket. The positioning rods match any set of positioning holes.

[0007] Preferably, the turning tool further includes a cooling unit for cooling different turning tools.

Different tools can be switched by rotation, allowing for rapid tool changes according to the machining process. After changing tools, a locking unit precisely positions and rigidly fixes the current tool, significantly improving machining efficiency and ease of operation. Since all tools are pre-installed and pre-set, the tedious disassembly, installation, and setting processes of traditional manual tool changing are avoided, greatly shortening tool change time, reducing operator workload and technical requirements, effectively minimizing positioning deviations and machining errors caused by human error, and improving machining accuracy and product consistency. Simultaneously, the locking unit ensures tool stability and rigidity during cutting, effectively suppressing vibration and tool displacement, further improving surface finish and tool life.

[0024] Please see Figure 1-5 This utility model provides a technical solution: a tool structure for turning chemical pump castings, including a turning machine tool 1 and a turning tool. The turning tool is fixedly mounted on the turning machine tool 1 and is used to turn the chemical pump castings on the turning machine tool 1. The turning tool includes a bracket 5 fixedly mounted on the turning machine tool 1, a rotary changing unit 2 for changing different turning tools 23, and two locking units 3 for fixing the changed turning tool 23. The rotary changing unit 2 is mounted on the bracket 5, and the two locking units 3 are also mounted on the bracket 5 and are linked with the rotary changing unit 2 to apply a locking force after the turning tool 23 is rotated into position to ensure that the turning tool 23 is stably positioned.

[0025] Specifically, the rotary changing unit 2 includes a rotating shaft 21, a tool holder 22, a cutting tool 23, and two positioning discs 24. The rotating shaft 21 is rotatably connected to the left and right sides of the bracket 5. The tool holder 22 is fixedly mounted on the rotating shaft 21. Different types of cutting tools 23 are provided on all four sides of the tool holder 22. Each side is equipped with a cutting tool 23 suitable for different machining processes, such as an external turning tool 23, a face turning tool 23, an internal turning tool 23, and a thread turning tool 23. By rotating the tool holder 22, the multi-station cutting tools 23 can be quickly switched, thereby completing machining operations including external turning and internal turning in a single clamping process. Multiple machining operations, including end face machining, boring of internal holes, and thread cutting, can be performed without the tedious process of repeated disassembly, installation, and tool setting, greatly shortening tool change time. Two positioning discs 24 are fixedly mounted on the rotating shaft 21, and the two positioning discs 24 are located on the left and right sides of the tool holder 22, respectively. Each positioning disc 24 has four sets of positioning holes, which correspond to four different cutting tools 23. The positioning holes are 90 degrees apart. Two locking units 3 are fixedly set on the left and right sides of the bracket 5. The positioning units and locking units 3 cooperate to fix the replaced cutting tool 23.

[0026] Specifically, the locking unit 3 includes a support housing 31, two linear guide rods 32, a sliding plate 33, a spring 34, a pull rod 35, and a set of positioning rods 36. The support housing 31 is fixedly installed on the outer right side of the bracket 5. The two linear guide rods 32 are fixedly installed between the outer right side of the bracket 5 and the inner right side of the support housing 31. The sliding plate 33 is slidably connected to the two linear guide rods 32, allowing the sliding plate 33 to move smoothly along the direction of the linear guide rods 32. The spring 34 is fixedly installed between the outer right side of the sliding plate 33 and the inner right side of the support housing 31, providing elastic restoring force. The pull rod 35 extends through the right side of the support housing 31, with one end of the pull rod 35 connected to the right side of the sliding plate 33. The slide plate 33 is fixedly connected to the side, with the pull rod 35 located inside the spring 34. Pulling the pull rod 35 externally can drive the slide plate 33 to move outward against the force of the spring 34. A set of positioning rods 36 are fixedly set on the left side of the slide plate 33 and move through the right side of the bracket 5. The positioning rods 36 are matched with any set of positioning holes. When the slide plate 33 moves outward, the positioning rods 36 disengage from the positioning holes, realizing the rotational replacement of the cutting tool 23. When the pull rod 35 is released, the spring 34 pushes the slide plate 33 to reset, and the positioning rods 36 are reinserted into the positioning holes, completing the precise positioning and rigid locking of the cutting tool 23, thereby ensuring the high efficiency and reliability of the tool changing process and the repeatability of the positioning accuracy during the machining process.

[0027] Specifically, the turning tool also includes a cooling unit 4 for cooling different turning tools 23, and the cooling unit 4 can perform a cooling operation on each turning tool 23.

[0028] Specifically, the cooling unit 4 includes a connecting seat 41, a cooling pipe 42, and a nozzle 43. The connecting seat 41 is fixedly installed on the top right side of the bracket 5. The cooling pipe 42 is fixedly installed through the connecting seat 41. One end of the cooling pipe 42 is connected to an external coolant supply device, and the other end of the cooling pipe 42 is provided with a nozzle 43, with the nozzle 43 outlet facing the cutting tool 23. The cooling unit 4 accurately sprays coolant onto the cutting area of ​​the currently working cutting tool 23 through the nozzle 43, effectively reducing the cutting temperature, reducing the wear of the cutting tool 23, extending the service life of the cutting tool 23, and preventing the workpiece from being affected by thermal deformation, thus improving the machining accuracy.

[0029] Specifically, the rotating shaft 21 is connected to the left and right sides of the bracket 5 through bearings. The outer ring of the bearing is fixedly connected to the bracket 5, and the inner ring of the bearing is interference-fitted with the rotating shaft 21.

[0030] Specifically, the vertical portion of the cooling pipe 42 is a retractable corrugated hose. A telescopic rod 44 is fixedly installed on the top of the connecting seat 41, and an adjusting seat 45 is fixedly installed on the top of the telescopic rod 44. The adjusting seat 45 is fixedly connected to the cooling pipe 42. The telescopic rod 44 and the retractable corrugated hose make the cooling pipe 42 highly adjustable, allowing the spray angle and distance of the nozzle 43 to be flexibly adjusted according to the height of different cutting tools 23 or the machining position, thereby achieving precise cooling of the cutting area. By moving the telescopic rod 44 up and down, the length of the corrugated hose can be quickly adjusted to adapt to the layout of different cutting tools 23, ensuring that the coolant can always effectively cover the cutting point.

[0031] Specifically, each group of positioning holes has four holes, and the four positioning holes are arranged in a ring. The ring arrangement design enables the cutting tool 23 to achieve multi-point positioning when it is fixed, thereby enhancing positioning accuracy and stability.

[0032] Working Principle: When machining chemical pump castings, the operator first selects the corresponding cutting tool 23 according to the machining requirements. By pulling the pull rod 35, the slide plate 33 moves outward along the linear guide rod 32. At this time, the positioning rod 36 disengages from a set of positioning holes in the positioning plate 24, releasing the lock on the rotary replacement unit 2. Then, the tool holder 22 is rotated manually or automatically to rotate the required cutting tool 23 to the working position. After releasing the pull rod 35, the spring 34 pushes the slide plate 33 back to its original position, and the positioning rod 36 re-inserts into the corresponding positioning hole, completing the precise positioning and rigid locking of the cutting tool 23, ensuring that the cutting tool 23 will not shift or loosen during machining. During the turning process, the cooling unit 4 precisely sprays coolant onto the cutting area of ​​the current working cutting tool 23 through the nozzle 43, effectively reducing the cutting temperature, reducing wear on the cutting tool 23, extending the service life of the cutting tool 23, and preventing the workpiece from being affected by thermal deformation, thus improving machining accuracy. When different cutting tools 23 need to be changed, the above operation can be repeated to achieve rapid switching of multi-station cutting tools 23. Multiple machining operations, including turning external diameters, turning end faces, boring internal holes, and thread cutting, can be completed in a single setup. This eliminates the need for tedious disassembly, installation, and tool setting, significantly reducing tool change time and improving machining efficiency. The height adjustability of the cooling pipe 42 allows the nozzle 43 to flexibly adjust the spray angle and distance according to the height of different cutting tools 23 or the machining position, ensuring that the coolant can always effectively cover the cutting point, thereby achieving precise cooling of different cutting tools 23.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
