[0002] A faucet is a common name for a water valve, used to control the flow of water. It has the functions of saving water and diverting water flow. Faucets are updated very quickly, from the old-fashioned cast iron process to electroplated knob type, and then to stainless steel single-temperature single-control faucets, stainless steel dual-temperature dual-control faucets, and semi-automatic kitchen faucets.

[0003] Turning, as a crucial step in transforming a blank into a finished product, connects with casting, forging, grinding, and assembly processes. The semi-finished product after turning can directly enter the polishing process, reducing intermediate handling and secondary clamping errors. It directly impacts product performance, cost, and market competitiveness, thus requiring turning equipment for faucet blanks. However, traditional turning equipment for faucet blanks cannot rotate the spindle holding the workpiece during processing, resulting in multiple clamping operations that cannot process multiple surfaces and holes in a single setup, reducing processing efficiency. Furthermore, traditional equipment cannot simultaneously clamp multiple turning inserts, and their replacement and maintenance are inconvenient, leading to a reduced lifespan of the turning inserts and further increasing economic losses.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-6 As shown, a turning device for a faucet blank includes a housing 1 and a multi-faceted nut box 2. A washer 19 is fixedly connected to the outside of the multi-faceted nut box 2, and a fixed plate 20 is rotatably connected to the outside of the washer 19. The housing 1 serves as the main frame of the device, providing structural protection and a mounting base. The washer 19 can prevent the clamping components 4 and the fixed plate 20 from contacting the outside of the multi-faceted nut box 2 during rotation, thus avoiding wear on the outside of the multi-faceted nut box 2. The fixed plate 20 is fixedly connected to the output end of a third drive motor 18, driving the clamping components 4 to rotate synchronously. It should be noted that the multi-faceted nut box 2 has twelve faces and an internal cavity to accommodate twelve sets of third drive motors 18. Each face has a set of clamping components 4, a washer 19, and a fixed plate 20, and the twelve sets of third drive motors 18 correspond to each set of clamping components 4, clamping different turning tools, and each face has an equal area.

[0017] The rotating assembly 3 is disposed on the inner wall of the outer shell 1. The rotating assembly 3 includes a first fixed post 301 fixedly connected to the inner wall of the outer shell 1. A rotating shaft 302 is rotatably connected to the inner wall of the first fixed post 301. A guide shaft 303 is fixedly connected to the outer side of the rotating shaft 302. The first fixed post 301 is used to support the rotating shaft 302, so that the rotating shaft 302 can rotate on the inner wall of the first fixed post 301. The rotating shaft 302 enables the second mold 10 to rotate synchronously under the drive of the first mold 9. The guide shaft 303 guides the rotation direction of the rotating shaft 302 to ensure the rotational stability of the workpiece and the second mold 10.

[0018] The clamping assembly 4 is disposed on the outside of the fixed disk 20. The clamping assembly 4 includes a positioning box 401 fixedly connected to the outside of the fixed disk 20. A toothed plate 402 is slidably connected to the inner wall of the positioning box 401. A clamp 403 is fixedly connected to the outside of the toothed plate 402 by bolts. A bevel gear 404 is rotatably connected to the inner wall of the positioning box 401. A gear plate 405 is rotatably connected to the inner wall of the positioning box 401. A trapezoidal threaded groove 406 is formed on the inner wall of the gear plate 405. The inner wall of the trapezoidal threaded groove 406 meshes with the teeth of the toothed plate 402. The positioning box 401 serves as the mounting base for the clamping assembly 4, ensuring the stable operation of the internal parts. The toothed plate 402 can slide on the inner wall of the positioning box 401, and synchronously drive the clamp 403 to move synchronously. The clamping assembly 403 clamps and opens / closes the turning tool. The clamp 403 is in direct contact with the turning tool and is driven by the gear plate 402. The bevel gear 404 serves as the power source for the entire clamping assembly 4, rotating to drive the gear disc 405. The gear disc 405 is the power transmission component of the clamping assembly 4, converting the rotational force of the bevel gear 404 into the rotational force of the gear disc 405. This rotational force is then converted into a linear force on the gear plate 402 via the trapezoidal thread groove 406. It should be noted that there are three sets of clamps 403 and bevel gears 404, distributed at 120° angles inside the positioning box 401. Furthermore, the surface of the clamp 403 has a laser-engraved grid pattern, which, together with a copper gasket, achieves soft-contact clamping, protecting the surface quality of the turning tool. Secondly... Figure 3 A set of positioning pins is fixed to the inner wall of the bevel gear 404 shown. The inner wall of the positioning pins has threaded holes. A set of support plates is fixed to the outer side of the fixing plate 20. The inner wall of the support plates also has threaded holes. The threaded holes of the support plates and positioning pins are used to lock the bevel gear 404 by inserting and screwing in bolts. In order to further ensure the stability of the clamping assembly 4, the above structure can be set in three sets, each set corresponding to a set of bevel gears 404. After the tool is clamped, they are tightened one by one.

[0019] The outer side of the bevel gear 404 meshes with the teeth of the gear disc 405. The inner wall of the outer shell 1 is fixedly connected to the cylinder 5 via a bracket. The piston rod of the cylinder 5 is fixedly connected to the fixed box 6. The inner wall of the fixed box 6 is fixedly connected to the first drive motor 7. The output end of the first drive motor 7 is fixedly connected to the connecting shaft 8. The bottom of the connecting shaft 8 is fixedly connected to the first mold 9. The cylinder 5 pushes the first drive motor 7 and the first mold 9 downward, so that the first mold 9 and the second mold 10 fit tightly together to clamp the blank. The fixed box 6 provides an installation platform for the first drive motor 7, so that the first drive motor 7 is not affected by the outside when it works. The first drive motor 7 serves as the power source of the rotating component 3, driving the first mold 9 to rotate, and then driving the second mold 10 to rotate synchronously. Under the action of the rotating component 3, the first mold 9 and the second mold 10 rotate stably. The first mold 9 serves as the main tool for installing and clamping the blank, so that the workpiece blank can remain stable during turning.

[0020] A second mold 10 is fixedly connected to the top of the rotating shaft 302. A positioning groove 11 is provided on the inner wall of the second mold 10. A positioning block 12 is fixedly connected to the bottom of the first mold 9. The positioning groove 11 and the positioning block 12 cooperate. Mounting holes 13 are provided on the inner walls of both the first mold 9 and the second mold 10. The second mold 10 and the first mold 9 cooperate to clamp and install the workpiece blank. The positioning groove 11 and the positioning block 12 cooperate to ensure a tight fit between the second mold 10 and the first mold 9. When the first mold 9 rotates, it stably drives the second mold 10 to rotate synchronously under the action of the rotating component 3. The mounting holes 13 provide mounting positions for the second mold 10 and the first mold 9. Figure 4 The mounting hole 13 shown is cross-shaped, and the second mold 10 and the first mold 9 each divide it in half, forming a complete mounting hole 13 when they are fitted together.

[0021] A second fixing post 14 is fixedly connected to the inner wall of the outer casing 1. A second drive motor 15 is fixedly connected to the inner wall of the second fixing post 14 through a mounting groove. A connecting plate 16 is fixedly connected to the output end of the second drive motor 15. The outer side of the connecting plate 16 is fixedly connected to the inner wall of the multifaceted nut box 2. The second fixing post 14 provides an installation position and support for the second drive motor 15. The second drive motor 15 drives the connecting plate 16 to rotate, which in turn drives the multifaceted nut box 2 to rotate synchronously. The connecting plate 16 serves as a power transmission component for the second drive motor 15.

[0022] An annular guide plate 17 is fixedly connected to the bottom of the connecting plate 16. The bottom of the annular guide plate 17 is rotatably connected to the inner wall of the second fixed column 14. The annular guide plate 17 provides guidance and support when the connecting plate 16 and the multi-faceted nut box 2 rotate, thereby improving the rotational stability of both.

[0023] The inner wall of the multi-faceted nut box 2 is fixedly connected to the third drive motor 18 via a support block. The output end of the third drive motor 18 is fixedly connected to the outer side of the fixed plate 20. The third drive motor 18 provides power for the rotation of the clamping assembly 4, which further drives the turning tool to rotate and process the blank workpiece.

[0024] The inner wall of the outer casing 1 is provided with a sliding groove 21, and a sliding plate 22 is slidably connected to the inner wall of the sliding groove 21. A handle 23 is fixedly connected to the outer side of the sliding plate 22, and a control panel 24 is fixedly connected to the outer side of the outer casing 1. The sliding groove 21 provides a guide for the sliding plate 22, allowing the sliding plate 22 to slide along the direction of the sliding groove 21. The handle 23 can pull the sliding plate 22. It should be noted that the sliding plate 22 can be fitted with glass or other transparent parts to protect the internal environment of the outer casing 1. The handle 23 drives the glass and its transparent materials to open and close. The control panel 24 integrates a PLC or DSP controller to realize the coordinated control of the speed and direction of the cylinder 5, the first drive motor 7, the second drive motor 15, and the third drive motor 18. In addition, the model of the control panel 24 is S7-1200 or TP1200 series.

[0025] Working principle: When machining a blank workpiece, the required cutting tool is first placed into the hollow structure of the positioning box 401. Then, a square-head screwdriver is used to screw into the bevel gear 404 to rotate, driving the gear plate 405 to rotate. When the gear plate 405 rotates, the horizontal rotational force is converted into a linear moving force of the three sets of gear plates 402 and the clamping fixture 403 through the trapezoidal thread groove 406. The gear plates 402 and the clamping fixture 403 move towards the axis of the positioning box 401 to clamp the turning tool. After clamping, the workpiece is placed into the mounting hole 13 of the second mold 10. The cylinder 5 is started, driving the fixing box 6, the first drive motor 7, and the first mold 9 to move towards the second mold 10. Then, the first drive motor 7 is started to rotate, driving the first mold 9, so that the positioning block 12 and the positioning groove 11... With the positions aligned, the first mold 9 and the second mold 10 are then tightly fitted together by the cylinder 5 to clamp the workpiece. After clamping, the third drive motor 18 is started to drive the turning tool to turn the workpiece. When different turning tools are needed to turn the workpiece, the second drive motor 15 is started through the control panel 24 to drive the connecting plate 16 to rotate, which in turn drives the multi-faceted nut box 2 to rotate. The required tool can be selected, allowing the turning tool to be changed without multiple machine stops. When it is necessary to perform face-changing processing on the workpiece, the first drive motor 7 is started to rotate and drive the first mold 9 and the second mold 10. Under the action of the rotating shaft 302 and the guide shaft 303, the first mold 9 and the second mold 10 can rotate smoothly to perform face-changing, realizing that multiple face-changing can be performed on a single workpiece clamping.
