Detailed Implementation

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a processing device for a bathroom floor drain includes a processing box 1. The processing box 1 is welded from thickened steel plates, and its overall frame has sufficient rigidity to effectively absorb and buffer the impact and vibration generated during the operation of the stamping mechanism 3 and the punching mechanism 4, preventing the box body from deforming and affecting the internal transmission. The bottom of the processing box 1 is provided with four self-locking casters 5 and support legs 6 arranged in a rectangular array. The self-locking casters 5 facilitate the movement and fixation of the device, and the support legs 6 provide stable support. The top of the processing box 1 has a rotating through hole that penetrates its inner cavity. The inner ring of the rotating through hole is rotatably mounted with a rotating station ring 2 using a bearing. The stamping mechanism 3 is provided on the right side of the processing box 1, and the punching mechanism 4 is provided at the rear end of the processing box 1. A servo motor is fixedly installed on the left side of the inner cavity of the processing box 1. The output shaft of the servo motor 11 passes through the inner cavity of the processing box 1 and is fixedly installed with the drive gear 111. The rotating station ring 2 is located on the side wall of the inner cavity of the processing box 1 and is fixedly installed with the external gear ring 21. The external gear ring 21 meshes with the drive gear 111 to drive the rotation of the rotating station ring 2. The inner ring of the rotating station ring 2 is fixedly installed with a cross-shaped fixing plate 22. The top of the four right angles of the cross-shaped fixing plate 22 is provided with a drive mechanism 24. The four drive mechanisms 24 are provided with a plate positioning box 23 on one side. The bottom center of the inner wall of the plate positioning box 23 is provided with a through hole 231 that runs vertically through the floor drain and is aligned with the inner cavity of the processing box 1 to accommodate and position the plate to be processed. The rotating station ring 2 is installed in the rotating through hole at the top of the processing box 1 through a high-strength bearing. The external gear ring 21 at its bottom and the drive gear 111 driven by the servo motor 11 form a transmission system. In order to protect the gear transmission pair, both the external gear ring 21 and the drive gear 111 are made of alloy steel and have been carburized and quenched. The tooth surface has high hardness and good wear resistance. At the same time, the gear meshing backlash has been precisely adjusted, and the axes of the two are kept parallel during installation to reduce wear caused by uneven force.

[0019] The mounting drive mechanism 24 includes two connecting fixing plates 241. One end of each connecting fixing plate 241 is mounted on the side wall of the plate positioning box 23, and the other end is fixed to the outer wall of the cross-shaped fixing plate 22. A vertical plate 242 is fixedly mounted on the top of each connecting fixing plate 241. A clamping drive motor 244 is fixedly mounted on the outer wall of one of the vertical plates 242. The clamping drive motor 244 is equipped with overload protection. By setting a current sensor in the power supply circuit of the clamping drive motor 244, the operating current of the motor is monitored in real time. When the current exceeds a preset safety threshold due to excessive clamping force or jamming, the PLC or other processor will immediately cut off the motor power or reverse the motor to release it, preventing excessive clamping force from deforming the plate. A positive and negative threaded rod 243 is fixedly mounted between the opposing surfaces of the two vertical plates 242 through the output shaft of the clamping drive motor 244. The positive and negative threaded rod 243 is fixed to the plate positioning box 242. The two opposite corners of the square box 23 are parallel. The outer walls of the positive and negative threaded rods 243 are respectively provided with threaded walls with opposite threads. The outer walls of the two threaded walls are threaded with movable plates 246. The opposite faces of the two vertical plates 242 are fixedly installed with limit slide rods 245. The movable plates 246 are slidably connected with the limit slide rods 245. The opposite faces of the two movable plates 246 are fixedly installed with push rods 247. The opposite ends of the two push rods 247 respectively penetrate to the two docking points of the inner cavity of the plate positioning square box 23 and are fixedly installed with right angle clamping plates 248. The bottom of the right angle clamping plates 248 is in contact with the bottom of the inner wall of the plate positioning square box 23 for clamping the plate. The adjacent side walls of the two connecting and fixing plates 241 are fixedly connected with protective plates 249. The protective plates 249 are located below the positive and negative threaded rods 243 to prevent debris from splashing onto the outer wall of the positive and negative threaded rods 243 and to ensure transmission accuracy. An anti-impact rubber pad is added at the connection between the connecting fixing plate 241 and the cross-shaped fixing plate 22 to attenuate the transmitted vibration. The impact-resistant rubber pad is not shown in the figure and is a well-known technology in the field. The protective plate 249 is not only used to prevent debris, but it is also made of steel plate with a certain toughness, which can play a certain role in force isolation and reinforcement.

[0020] like Figure 5As shown, the stamping mechanism 3 includes an L-shaped mounting plate 31 fixedly installed on the right side of the processing box 1. A hydraulic cylinder 32 is fixedly installed at the top of the horizontal position of the L-shaped mounting plate 31. The output end of the hydraulic cylinder 32 extends through to the bottom of the horizontal position of the L-shaped mounting plate 31 and is fixedly installed with a lifting plate 33. Guide rods 36 are fixedly installed on both sides of the top of the lifting plate 33. Both guide rods 36 are slidably connected to the horizontal position of the L-shaped mounting plate 31 to ensure smooth lifting. A stamped square column 34 is fixedly installed at the bottom of the lifting plate 33. A drain hole stamping cylinder 35 is fixedly installed at the bottom of the stamped square column 34. The drain hole stamping cylinder 35 is vertically aligned with the drain punching through hole 231 rotated downwards. It is used to stamp the center of the plate to the bottom of the plate positioning box 23 to form the preliminary shape of the drain base. The materials of the drain hole stamping cylinder 35 and the stamped square column 34 are both made of high-strength alloy steel, and are also subjected to quenching treatment to improve strength. The punching mechanism 4 includes an L-shaped mounting plate 41 fixedly installed on the rear side of the processing box 1. A hydraulic cylinder 42 is fixedly installed at the top of the horizontal position of the L-shaped mounting plate 41. The output end of the hydraulic cylinder 42 extends through to the bottom of the horizontal position of the L-shaped mounting plate 41 and is fixedly installed with a lifting plate 43. A conical punching block 44 is fixedly installed at the bottom of the lifting plate 43. The conical punching block 44 is vertically aligned with the drain punching through hole 231 rotated downwards, and is used to punch holes in the stamped plate. Guide rods 45 are fixedly installed on both sides of the top of the lifting plate 43. Both guide rods 45 are slidably connected to the horizontal position of the L-shaped mounting plate 41 to ensure the stability of the punching process. The force transmission paths of the stamping mechanism 3 and the punching mechanism 4 are strictly limited. The hydraulic cylinder 32 drives the lifting plate 33 to move smoothly down the guide rod 36. The vertical downward force exerted by the drain hole punching cylinder 35 on the plate is mostly borne by the sturdy L-shaped mounting plate 31 and the side wall of the processing box 1. Similarly, the hydraulic cylinder 42 drives the lifting plate 43 to move along the guide rod 45. The punching force of the conical punching block 44 is mainly borne by the L-shaped mounting plate 41 and the rear wall of the processing box 1. This force transmission path design ensures that the main force is absorbed by the main structure of the processing box 1 and will not be transmitted back to the rotary transmission system of the rotating station ring 2 or the plate clamping drive system.

[0021] The signal output terminal of the servo motor 11 is electrically connected to the oil valve signal input terminal of the hydraulic cylinder 32 and the hydraulic cylinder 42 to achieve coordinated control and ensure that the stamping mechanism 3 and the punching mechanism 4 operate in sequence when the rotating station ring 2 rotates. When the rotating station ring 2 rotates to a specific station such as the stamping station or the punching station, the station position is detected by a position sensor such as a photoelectric sensor or an encoder. The servo motor 11 sends a signal to trigger the hydraulic cylinder 32 or the hydraulic cylinder 42 to act in sequence. For example, when the plate positioning box 23 rotates to the bottom of the stamping mechanism 3, the sensor detects the signal, and the PLC controls the hydraulic cylinder 32 to descend and perform stamping. The hydraulic systems of both the hydraulic cylinder 32 and the hydraulic cylinder 42 are equipped with relief valves to prevent overload.

[0022] like Figure 6 As shown, a fixed plate 12 is fixedly installed on the left side of the inner wall of the processing box 1. An electric push rod 121 is fixedly installed at the bottom of the fixed plate 12. The output end of the electric push rod 121 extends through to the top of the fixed plate 12 and is fixedly installed on a lifting plate 122. A grinding servo motor 123 is fixedly installed on the top of the lifting plate 122. A grinding disc 124 is fixedly installed on the output shaft of the grinding servo motor 123. The grinding disc 124 is located at the bottom of the drain punching through hole 231 that rotates upwards. It is used to grind the burrs on the plate that extend to the bottom of the plate positioning box 23 after punching. A limit slide rod 125 is also fixedly installed on the top of the fixed plate 12. The lifting plate 122 is slidably connected to the limit slide rod 125 to ensure smooth lifting and lowering during grinding. The electric push rod 121 controls the contact pressure between the grinding disc 124 and the bottom of the plate through a limit switch or position feedback to avoid over-grinding. A placement frame 13 is fixedly installed below the inner ring of the processing box 1. A pull-out through hole 14 is opened on the front side of the processing box 1, which passes through its inner cavity. The bottom of the inner ring of the pull-out through hole 14 is flush with the bottom of the placement frame 13. A debris collection drawer 131 is provided on the top of the placement frame 13. The debris collection drawer 131 is slidably connected to the pull-out through hole 14. A pull-out handle 132 is fixedly installed on the front side of the debris collection drawer 131 to facilitate the collection and cleaning of debris generated during the processing.

[0023] The working principle of the processing device for this bathroom floor drain will be explained in detail below.

[0024] like Figure 1-6As shown, firstly, the stainless steel sheet to be processed is placed in the sheet positioning box 23. The clamping drive motor 244 is started, driving the positive and negative threaded rods 243 to rotate. Since the threads on both sides of the positive and negative threaded rods 243 are opposite, the two moving plates 246 move towards or away from each other along the limiting slide bar 245. The push rod 247 drives the right-angle clamping plate 248 to clamp or release the sheet, realizing the rapid positioning and fixing of the sheet. Subsequently, the servo motor 11 is started, and through the meshing of the drive gear 111 and the external gear ring 21, the rotating station ring 2 is driven to rotate, thereby driving the cross-shaped fixing plate 22 and its four The plate positioning box 23 passes through different workstations in sequence. When one of the plate positioning boxes 23 rotates to below the stamping mechanism 3, the servo motor 11 sends a signal to the hydraulic cylinder 32. The hydraulic cylinder 32 pushes the lifting plate 33 down, and guided by the guide rod 36, it causes the stamping column 34 and the drain hole stamping column 35 to move downward, stamping the plate to form the preliminary shape of the drain base. After stamping, the rotating workstation ring 2 continues to rotate, moving the stamped plate to below the punching mechanism 4. The servo motor 11 sends a signal to the hydraulic cylinder 42, and the hydraulic cylinder 42 pushes the lifting plate 43 down. The cone-shaped punching block 44 moves downwards, guided by guide rod 45, to punch holes in the sheet metal. After punching, the rotating station ring 2 rotates the sheet metal above the grinding station. The electric push rod 121 pushes the lifting plate 122 upwards, causing the grinding disc 124 to contact the burrs on the bottom of the sheet metal. At the same time, the grinding servo motor 123 drives the grinding disc 124 to rotate, performing grinding to remove burrs. The debris generated during processing falls into the debris collection drawer 131 below. The debris collection drawer 131 is periodically pulled out using the pull handle 132 for cleaning. The entire processing is highly automated, with the rotating mechanism... This device enables continuous multi-process machining, reduces repetitive positioning errors, and improves production efficiency and machining accuracy. At the same time, its compact structure saves space and reduces manufacturing costs. In the stamping and punching stations, the huge instantaneous force is directly transmitted and dissipated through the robust L-shaped mounting plate and machining box, effectively avoiding the transmission path of the positive and negative thread rods 243 and the meshing area of ​​the external gear ring 21. This force path planning and the reinforced design of key transmission components together ensure that the equipment can maintain high-precision transmission and positioning under long-term and frequent stamping operations, significantly improving the reliability and service life of the equipment.
