[0001] The invention relates to the technical field of hardware processing equipment, and in particular to a high-efficiency polishing machine with multiple stations. Background Art

[0002] Polishing machines are specially designed for surface treatment of hardware such as steel, aluminum and copper. They can quickly repair deep scratches and minor scrapes, quickly grind and polish welds, water inlet marks, traces of oxide film, stains and paint, etc. They are suitable for deburring, forming rounded corners, decorative metal processing, and will not form shadows, transition zones and uneven decorative surfaces during the processing. They are important equipment for metal product production lines. There are many types of hardware, such as door handles, faucets, connecting nuts and other products that are formed by metal processing. There are two symmetrical mounting holes on the door handle.

[0003] The existing polishing machine only has one set of workpiece fixtures to clamp and fix the hardware, and polish the hardware with abrasive particles, which makes the efficiency of the equipment in processing the hardware obviously insufficient. Although some polishing machines have improved the efficiency of hardware processing to a certain extent by adding multiple sets of workpiece fixtures in the polishing cylinder, the equipment still needs to stop working to load and unload the hardware, which seriously affects the production and processing efficiency of the hardware. Therefore, it is very necessary to improve the existing polishing machine. Summary of the invention

[0006] By adopting the above technical scheme, a plurality of polishing rollers are fixedly connected between the first turntable and the second turntable, and the polishing rollers include a fixed cylinder, a movable cover and a workpiece hanger. The main motor is movably connected to the fourth connecting structure through a transmission assembly, so that the main motor can drive multiple polishing rollers to perform polishing processing at the same time, effectively improving the production and processing efficiency of hardware. At the same time, the transposition motor is movably connected to the second connecting structure, so that the transposition motor can drive the polishing mechanism to rotate through the second connecting structure, and then drive the polishing roller to perform transposition work, and cooperate with an extra group of polishing rollers to load and unload hardware, so as to achieve the effect of loading and unloading without stopping, effectively improving the production and processing efficiency of hardware.

[0007] The present invention is further configured as follows: the first connecting structure and the second connecting structure are respectively fixedly connected to the first turntable and the second turntable by bolts, and the first connecting structure and the second connecting structure are also movably connected to the frame and the control cabinet by sleeve-arranging a first connecting bearing, and the second connecting structure is provided with a transposition slave gear adapted to the transposition motor, and the transposition slave gear is fixedly connected to the second turntable.

[0008] By adopting the above technical solution, the first connecting structure and the second connecting structure are movably connected to the frame and the control cabinet respectively by sleeve-arranging the first connecting bearing, so that the polishing mechanism can rotate independently relative to the frame and the control cabinet. At the same time, by arranging a shifting follower gear on the second connecting structure, the shifting motor can drive the second turntable to rotate through the driven gear, and then drive the polishing roller to perform the shifting work, so as to achieve the effect of loading and unloading without stopping, and effectively improve the production and processing efficiency of hardware.

[0009] The present invention is further configured as follows: the third connecting structure and the fourth connecting structure are movably connected to each other at both ends of the fixed cylinder by setting a second connecting bearing, the fourth connecting structure is provided with a polishing gear adapted to the transmission structure, and the fourth connecting structure is also provided with a first fixed groove adapted to the workpiece hanger.

[0010] By adopting the above technical solution, the third connecting structure and the fourth connecting structure are connected to the fixed cylinder through the second connecting bearing, so that the workpiece hanger can rotate independently relative to the polishing drum. At the same time, the main motor drives the polishing gear through the transmission structure, and then drives the workpiece hanger in the polishing drum to rotate, so that the hardware can fully carry out polishing processing and ensure the polishing effect of the hardware.

[0011] The present invention is further configured as follows: a locking structure adapted to the workpiece hanger is provided on the third connecting structure, the locking structure includes a matching locking fixed block and a locking movable block, one end of the locking movable block is hingedly connected to the locking fixed block, and the other end is detachably connected to the locking fixed block by setting a locking bolt, and a second fixing groove adapted to the workpiece hanger is also provided on the locking movable block and the locking fixed block.

[0012] By adopting the above technical solution, the locking structure cooperates with the locking fixed block and the locking movable block to facilitate the installation and disassembly of the workpiece hanger and the loading and unloading of hardware. At the same time, the locking structure keeps synchronization with the polishing gear with the cooperation of the second bearing, and the main motor can drive the workpiece hanger to rotate, so that the hardware on the tool hanger can be fully polished.

[0013] The present invention is further configured as follows: the main motor is movably connected to the transmission structure by sequentially arranging a main pulley, a transmission belt, a slave pulley and a plurality of reduction gears; the transmission structure includes a transmission shaft and a first transmission gear and a second transmission gear fixed at both ends of the transmission shaft; and two adjacent groups of transmission structures are meshed with each other through the first transmission gear, the reduction gear is meshed with the first transmission gear, the reduction gear is located in the transmission fixing frame, and the second transmission gear is meshed with the polishing gear.

[0014] By adopting the above technical solution, the main motor is connected through the main pulley, the transmission belt, the slave pulley, the reduction gear and the transmission structure, and then the polishing roller is driven by the transmission structure to perform polishing processing. The adjacent transmission structures are meshed and connected with each other through the first transmission gear, so that the reduction gear drives one first transmission gear to make other transmission structures move together, and then drive the polishing roller other than that used for loading and unloading to perform polishing work. The reduction gear reduces the rotation by means of the large and small gear ratio, thereby reducing the rotation speed of the transmission structure to avoid excessive rotation speed affecting the polishing effect of hardware.

[0015] The present invention is further configured as follows: the transposition motor is fixedly connected to the transmission fixed frame, the transposition motor is provided with a transposition rotating shaft adapted thereto, the transposition rotating shaft is meshedly connected with the transposition slave gear by providing a transposition main gear, and the transposition rotating shaft and the transmission rotating shaft are movably connected to the transmission fixed frame through a rotating shaft bearing.

[0016] By adopting the above technical solution, the transposition motor drives the transposition slave gear fixed on the second turntable through the transposition shaft and the transposition master gear, so that the transposition motor can drive the second turntable to rotate, and then when the equipment is loading and unloading, the transposition motor can drive the polishing mechanism to perform transposition work, achieving the effect of loading and unloading without stopping, effectively improving the production and processing efficiency of hardware.

[0017] The present invention is further configured as follows: a limiting structure adapted to the second turntable is also provided on one side of the transmission fixed frame, the limiting structure includes a limiting cylinder and a limiting rod fixedly connected to the piston rod of the limiting cylinder, a limiting protrusion adapted to the polishing roller is provided on the second turntable, a limiting groove adapted to the limiting rod is provided on the limiting protrusion, the limiting protrusion is evenly distributed in a circular shape around the edge of the second turntable, and a reinforcing protrusion integral with the limiting protrusion is also provided on the outer side of the limiting protrusion.

[0018] By adopting the above technical solution, the limiting structure ensures that after the transposition motor drives the polishing mechanism to complete the transposition work, the transposition motor will not drive the second turntable on the polishing mechanism to continue to rotate, thereby improving the overall reliability of the equipment. When the polishing mechanism needs to be transposed, the limiting cylinder drives the limiting rod to contract, so that the limiting rod is separated from the limiting groove, and the transposition motor can drive the second turntable to rotate and transpose normally. Conversely, the limiting cylinder drives the limiting rod to extend, so that the limiting rod is inserted into the limiting groove, and the second turntable remains fixed and does not rotate. Even if the transposition motor works, it cannot drive the second turntable to rotate.

[0019] The present invention is further configured as follows: a ventilation cavity is formed between the first turntable, the second turntable and several of the fixed cylinders, the number of fixed cylinders is set to at least three groups, and the second turntable and the second connecting structure are provided with mutually connected ventilation slots and ventilation holes, the ventilation holes are also interconnected with the control cabinet, and a ventilation pressure cover with ventilation holes is also provided at the ventilation holes, a heat dissipation fan adapted to the ventilation holes is provided in the control cabinet, and several heat dissipation parts are provided on the fixed cylinder and the movable cover, the heat dissipation parts cooperate with the ventilation cavity, the heat dissipation part upper cover is provided with a metal filter fixedly connected thereto, and the heat dissipation part is also provided with heat dissipation holes distributed in a matrix shape.

[0020] By adopting the above technical solution, a ventilation cavity is formed between the first turntable, the second turntable and the fixed cylinder. The heat dissipation fan blows air into the ventilation cavity through the ventilation holes, and then enters the interior of the polishing drum through the heat dissipation holes to dissipate heat inside the polishing drum, thereby preventing the internal temperature from being too high and shortening the service life. At the same time, hardware and worn abrasive particles in the polishing drum during the polishing process are discharged from the heat dissipation holes, and the metal filter can effectively prevent abrasive particles of a size that meets the requirements from being discharged from the heat dissipation holes.

[0022] By adopting the above technical solution, the first seal and the second seal seal the fixed cylinder, the first turntable and the second turntable, ensuring that the heat dissipation fan can effectively blow air into the ventilation cavity into the polishing drum through the heat dissipation holes to ensure the heat dissipation performance. At the same time, the cleaning port is used to discharge the polishing debris passing through the heat dissipation holes to avoid the polishing debris clogging the polishing holes and affecting the heat dissipation performance.

[0023] The present invention is further configured as follows: the workpiece hanger includes a workpiece rotating shaft and a plurality of support frames compatible with the workpiece rotating shaft, the two ends of the workpiece rotating shaft are respectively detachably connected to the third connecting structure and the fourth connecting structure, and fixed brackets compatible with the hardware are evenly distributed on the support frame.

[0026] 1. A plurality of polishing rollers are fixedly connected between the first turntable and the second turntable. The polishing rollers include a fixed cylinder, a movable cover and a workpiece hanger. The main motor is movably connected to the fourth connecting structure through a transmission assembly, so that the main motor can simultaneously drive a plurality of polishing rollers to perform polishing processing, effectively improving the production and processing efficiency of hardware. At the same time, the transposition motor is movably connected to the second connecting structure, so that the transposition motor can drive the polishing mechanism to rotate through the second connecting structure, thereby driving the polishing roller to perform transposition work, and cooperate with an additional group of polishing rollers to load and unload hardware, so as to achieve the effect of loading and unloading without stopping the machine, effectively improving the production and processing efficiency of hardware;

[0027] 2. A ventilation cavity is formed between the first turntable, the second turntable and the fixed cylinder and is sealed by the first seal and the second seal. The heat dissipation fan blows air into the ventilation cavity through the ventilation holes, and then enters the interior of the polishing drum through the heat dissipation holes to dissipate heat inside the polishing drum to prevent the internal temperature from being too high and shortening the service life.

The extra group of polishing rollers 23 is used for loading and unloading of hardware 63. When the polishing rollers 23 are shifted to the loading and unloading position, the movable cover 232 is located on the upper part of the fixed cylinder 231 to prevent the internal abrasive particles from falling out during loading and unloading, affecting the polishing effect. The shifting motor 35 and the second connecting structure 5 are movably connected to each other; a plurality of polishing rollers 23 are fixedly connected between the first turntable 21 and the second turntable 22, and the polishing rollers 23 include a fixed cylinder 231 and a movable cover 232 and a workpiece hanger 6, and the main The motor 32 is movably connected to the fourth connecting structure 8 through the transmission assembly, so that the main motor 32 can simultaneously drive multiple polishing rollers 23 to perform polishing processing, effectively improving the production and processing efficiency of the hardware 63.

[0046] like Figure 3As shown, the first connecting structure 4 and the second connecting structure 5 are respectively fixedly connected to the first turntable 21 and the second turntable 22 by bolts, and the first connecting structure 4 and the second connecting structure 5 are also movably connected to the frame 1 and the control cabinet 3 by sleeve-arranging the first connecting bearing 41, and the second connecting structure 5 is provided with a transposition slave gear 51 adapted to the transposition motor 35, and the transposition slave gear 51 is fixedly connected to the second turntable 22; the first connecting structure 4 and the second connecting structure 5 are respectively movably connected to the frame 1 and the control cabinet 3 by sleeve-arranging the first connecting bearing 41, so that the polishing mechanism 2 rotates independently relative to the frame 1 and the control cabinet 3, and at the same time, by arranging the transposition slave gear 51 on the second connecting structure 5, the transposition motor 35 can drive the second turntable 22 to rotate through the driven gear, and then drive the polishing roller 23 to perform transposition work, so as to achieve the effect of loading and unloading without stopping, and effectively improve the production and processing efficiency of the hardware 63.

[0047] like Figure 3 and 4 As shown, the third connecting structure 7 and the fourth connecting structure 8 are movably connected to each other at both ends of the fixed cylinder 231 by setting a second connecting bearing 71, and the fourth connecting structure 8 is provided with a polishing gear 81 adapted to the transmission structure 34, and the fourth connecting structure 8 is also provided with a first fixed groove 82 adapted to the workpiece hanger 6; the third connecting structure 7 and the fourth connecting structure 8 are connected to the fixed cylinder 231 through the second connecting bearing 71, so that the workpiece hanger 6 can rotate independently relative to the polishing drum 23, and at the same time, the main motor 32 drives the polishing gear 81 to move through the transmission structure 34, and then drives the workpiece hanger 6 in the polishing drum 23 to rotate, so that the hardware 63 can fully carry out the polishing processing work, thereby ensuring the polishing effect of the hardware 63.

[0048] like Figure 4 As shown, the third connecting structure 7 is provided with a locking structure 72 compatible with the workpiece hanger 6, the locking structure 72 includes a matching locking fixed block 721 and a locking movable block 722, one end of the locking movable block 722 is hingedly connected to the locking fixed block 721, and the other end is detachably connected to the locking fixed block 721 by setting a locking bolt, and the locking movable block 722 and the locking fixed block 721 are also provided with a second fixing groove 723 compatible with the workpiece hanger 6; the locking structure 72 facilitates the installation and disassembly of the workpiece hanger 6 and the loading and unloading of the hardware 63 through the mutual cooperation of the locking fixed block 721 and the locking movable block 722, and at the same time, the locking structure 72 keeps synchronization with the polishing gear 81 under the cooperation of the second bearing, and the main motor 32 can drive the workpiece hanger 6 to rotate, so that the hardware 63 on the tool hanger can be fully polished.

[0049] like Figure 3 as well as Figures 5 to 8As shown, the main motor 32 is movably connected with the transmission structure 34 by sequentially arranging a main pulley 321, a transmission belt, a slave pulley 322 and a plurality of reduction gears 323. The transmission structure 34 includes a transmission shaft 341 and a first transmission gear 342 and a second transmission gear 343 fixed at both ends of the transmission shaft 341. Two adjacent groups of transmission structures 34 are meshed with each other through the first transmission gear 342, the reduction gear 323 is meshed with the first transmission gear 342, the reduction gear 323 is located in the transmission fixing frame 33, and the second transmission gear 343 is meshed with the polishing gear 81; the main motor 32 is connected to the transmission structure 34 through the main pulley 321, the transmission belt, the slave pulley 322, the reduction gear 323, and the transmission structure 34, and then drives the polishing roller 23 to perform polishing processing. The adjacent transmission structures 34 are meshed and connected with each other through the first transmission gear 342, so that the reduction gear 323 drives one first transmission gear 342 to make other transmission structures 34 move together, and then drive the polishing roller 23 other than that used for loading and unloading to perform polishing work. The reduction gear 323 reduces the rotation by means of the large and small gear ratio, thereby reducing the rotation speed of the transmission structure 34 to avoid excessive rotation speed affecting the polishing effect of the hardware 63.

[0050] like Figures 6 to 8 As shown, the transposition motor 35 is fixedly connected to the transmission fixed frame 33, and a transposition shaft 351 matched therewith is arranged on the transposition motor 35. The transposition shaft 351 is meshed with the transposition slave gear 51 by setting a transposition main gear 352, and the transposition shaft 351 and the transmission shaft 341 are movably connected to the transmission fixed frame 33 through shaft bearings; the transposition motor 35 drives the transposition slave gear 51 fixed on the second turntable 22 through the transposition shaft 351 and the transposition main gear 352, so that the transposition motor 35 can drive the second turntable 22 to rotate, and then when the equipment is loading and unloading, the transposition motor 35 can drive the polishing mechanism 2 to perform transposition work, so as to achieve the effect of loading and unloading without stopping, and effectively improve the production and processing efficiency of the hardware 63.

[0051] The working process is as follows: the workpiece hanger 6 fixed with the hardware 63 is assembled as a whole into the polishing roller 23 at the loading and unloading position, the electric control box 31 of the control cabinet 3 is started, and the transposition motor 35 in the control cabinet 3 drives the polishing mechanism 2 to perform the transposition work, and the polishing roller 23 equipped with the workpiece hanger 6 moves with the transposition motor 35 and rotates to the position of the next station to complete the transposition work. At the same time, the new polishing roller 23 will also rotate to the loading and unloading position with the transposition motor 35, and the new workpiece hanger 6 is assembled into the polishing roller 23. Then, the main motor 32 in the control cabinet 3 starts to drive the polishing roller 23 to perform the polishing work after the transposition work is completed. Since the number of transmission components is one group less than the number of polishing rollers 23, the main motor 32 will not drive the upper The polishing roller 23 at the unloading position performs polishing work, so the loading and unloading of the hardware 63 will not be affected during the polishing work. The polishing mechanism 2 repeats the replacement work and installation of the workpiece hanger 6 until the first polishing roller 23 equipped with the hardware 63 is rotated to the loading and unloading position again, the polishing roller 23 is opened to take out the tool hanger as a whole, and the polishing process of the entire hardware 63 is completed. At the same time, the new workpiece hanger 6 is assembled into the polishing roller 23, waiting for the replacement motor 35 to perform the replacement work, and the above steps are repeated subsequently, so as to achieve the effect of loading and unloading of the equipment as a whole without stopping, thereby effectively improving the production and processing efficiency of the hardware 63, wherein the time period between each replacement of the polishing mechanism 2 and the next replacement is set to be no less than 30 minutes.

[0052] Embodiment 2: This embodiment is based on embodiment 1. Figures 10 to 12 As shown, a limiting structure 36 adapted to the second turntable 22 is also provided on one side of the transmission fixing frame 33, and the limiting structure 36 includes a limiting cylinder 361 and a limiting rod 362 fixedly connected to the piston rod of the limiting cylinder 361. A limiting protrusion 363 adapted to the polishing roller 23 is provided on the second turntable 22, and a limiting groove adapted to the limiting rod 362 is provided on the limiting protrusion 363. The limiting protrusion 363 is evenly distributed in a circular shape around the edge of the second turntable 22. A reinforcing protrusion integrated with the limiting protrusion 363 is also provided on the outer side of the limiting protrusion 363. The reinforcing protrusion can improve the mechanical strength of the limiting protrusion 363 and extend its service life. Lifespan: The limiting structure 36 ensures that after the transposition motor 35 drives the polishing mechanism 2 to complete the transposition work, the transposition motor 35 will not drive the second turntable 22 on the polishing mechanism 2 to continue rotating, thereby improving the overall reliability of the equipment. When the polishing mechanism 2 needs to be transposed, the limiting cylinder 361 drives the limiting rod 362 to contract, so that the limiting rod 362 is separated from the limiting groove, and the transposition motor 35 can drive the second turntable 22 to rotate and transpose normally. On the contrary, the limiting cylinder 361 drives the limiting rod 362 to extend, so that the limiting rod 362 is inserted into the limiting groove, and the second turntable 22 remains fixed and does not rotate. Even if the transposition motor 35 works, it cannot drive the second turntable 22 to rotate.

[0053] Its working process is based on the first embodiment: during the transposition operation, the electric control box 31 controls the limit cylinder 361 to move, so that the limit cylinder 361 drives the limit rod 362 to contract, that is, the limit rod 362 and the limit groove are separated from each other, and the transposition motor 35 can drive the second turntable 22 to rotate normally to complete the transposition work; during the non-transposition operation, the limit cylinder 361 drives the limit rod 362 to extend, so that the limit rod 362 is inserted into the limit groove, and the limit rod 362 and the second turntable 22 are fixed to each other, so that the second turntable 22 cannot rotate and the transposition work cannot be performed.

[0054] Embodiment 3: This embodiment is based on embodiment 2.
