Description

Technical Field

[0001] This utility model belongs to the field of steel cabinet panel processing technology, and specifically relates to a high-efficiency grinding device for steel cabinet panels. Background Technology

[0002] In the field of mechanical manufacturing, grinding is a key surface treatment process. By using the cutting action of abrasives on a grinding machine, it can accurately remove excess layers from the surface of a workpiece, enabling the workpiece to meet the predetermined surface quality requirements. Therefore, it is widely used in the processing and manufacturing of various parts.

[0003] Chinese Patent No. CN218613189U discloses a high-efficiency grinding device for steel cabinet panels. This device provides a new solution for grinding steel cabinet panels by installing a processing box on a base and equipping it with a grinding mechanism and dust removal components. The device utilizes a third cylinder on the lifting seat to drive a positioning plate to clamp the steel plate. Rubber pads increase friction, ensuring stability during grinding. Simultaneously, a second motor drives a lead screw to move the lifting plate up and down, moving a level up and down. The laser illumination from the level enables efficient and precise grinding of the steel plate, effectively avoiding large grinding deviations.

[0004] However, in practical applications, this device still has obvious shortcomings. Its clamping function can only fix the steel plate to be polished and cannot flexibly adjust the front and back displacement of the steel plate. When it is necessary to polish the steel plate to be polished, it is difficult to achieve all-round polishing. It only has a lifting function, which easily creates polishing dead corners. Obviously, it limits its use in complex processing scenarios, so it needs to be improved. Utility Model Content

[0023] Example

[0024] refer to Figures 1 to 4 This embodiment of a high-efficiency polishing device for steel cabinet panels includes a base plate 1, with clamping mechanisms 2 fixedly installed on both sides of the top of the base plate 1, and a polishing mechanism 3 fixedly installed in the middle of the rear side of the top of the base plate 1.

[0025] The clamping mechanism 2 includes a fixed base 21, which is fixedly installed on the middle of the top two sides of the base plate 1. A fixed frame 22 is fixedly installed on the top of the fixed base 21. A first electric push rod 23 is fixedly installed on the upper end of the fixed frame 22. The output end of the first electric push rod 23 passes through the fixed frame 22 and is fixedly installed with a clamping assembly 24. A support assembly 25 is provided at the bottom of the clamping assembly 24. The bottom of the support assembly 25 is fixedly connected to the top of the base plate 1. A synchronous drive system can be set on the base plate 1 of this device. The synchronous drive system is specifically a motor drive module, which can be an L298N drive board. It can provide sufficient drive current to the motor and control the forward and reverse rotation of the motor. The operating status of the motors is adjusted by receiving control signals. This is achieved using a control module, specifically an Arduino development board, which has abundant input / output interfaces. Control signals can be output through programming. Connecting the Arduino to the L298N driver board and setting control commands in the program, the Arduino simultaneously sends a start signal to the L298N when the motors need to be driven, causing both motors to run simultaneously. When the motors need to be stopped, the Arduino simultaneously sends a stop signal, achieving synchronous stopping of both motors. Alternatively, a PLC controller can be used, which offers high stability and strong anti-interference capabilities. When paired with a suitable motor driver module, it can also accurately control two motors. The motor starts and stops simultaneously. To reduce operating costs during application, and to polish the steel plate 26, a drive assembly 244 can be installed on one clamping mechanism 2 while the other clamping mechanism 2 can operate without the drive assembly 244. If the steel plate 26 to be polished is large or heavy, two clamping mechanisms 2, each equipped with a drive assembly 244, are required. The specific application can be flexibly selected based on production and processing needs. During polishing, the device is first fixed to the base plate 1, and the steel plate 26 to be polished is placed on the receiving plate 243. The ball bearings 255 reduce friction during steel plate movement. In the clamping mechanism 2, the first electric pusher on the two side fixing frames 22... The rod 23, through its telescopic movement, drives the clamping assembly 24 to adjust the left and right displacement of the steel plate. At the same time, it works in conjunction with the L-shaped structure formed by the clamping plate 242 and the receiving plate 243 to complete the initial positioning of the steel plate. The synchronous drive system plays a key role, using an L298N motor drive board in conjunction with an Arduino development board or a PLC controller. When the motor needs to be driven, the control module (Arduino or PLC) sends a start signal to the L298N drive board. The drive board provides current to the motor and controls its forward and reverse rotation, so that the two motors run simultaneously, driving the worm 2444, worm wheel 2445 and drive roller 2446 of the drive assembly 244 to rotate, and the front and rear displacement of the steel plate is adjusted through friction.If a stop is required, the control module sends a stop signal to synchronously stop the motor. The support block 254 in the support assembly 25 slides within the movable groove 253, ensuring stable movement of the receiving plate 243. After positioning, the second electric push rod 34 of the polishing mechanism 3 adjusts the height of the polishing wheel 36, and the first motor 35 drives the polishing wheel 36 to rotate at high speed to polish the steel plate. During the polishing process, the position of the steel plate can be adjusted again through the synchronous drive system as needed to achieve comprehensive and uniform polishing. In addition, the drive group 244 can be flexibly installed on one or two clamping mechanisms 2 according to the volume, weight, and cost requirements of the steel plate to adapt to different production and processing scenarios.

[0026] refer to Figures 1-2 The polishing mechanism 3 includes a concave arm 31, which is fixedly installed in the middle of the back of the substrate 1. A support arm 32 is fixedly installed on the top of the concave arm 31, and a mounting base 33 is fixedly installed at the front end of the top of the support arm 32. A second electric push rod 34 is fixedly installed on the top of the mounting base 33. A first motor 35 is fixedly installed through the mounting base 33 at the output end of the second electric push rod 34. A polishing wheel 36 is installed at the output end of the first motor 35 by bolts. Mounting holes 4 are provided at the four corners of the substrate 1. The mounting holes 4 are countersunk holes. During the application of this device, the support arm 32 and the concave arm 31 are made of stainless steel. The external corners of the support arm 32 and the concave arm 31 are also rounded. In this high-efficiency polishing device for steel cabinet panels, the countersunk holes at the four corners of the substrate 1 can be used to securely install the device on the workbench with bolts. The countersunk design allows the bolt head to sink into the hole, avoiding protrusion and affecting the process. Operation may cause safety issues. When the steel plate needs to be polished, the polishing mechanism 3 starts to operate. The concave arm 31 is fixed in the middle of the back of the substrate 1, providing a stable support base for the entire polishing mechanism 3. The support arm 32 at the top further enhances the structural stability and adjusts the height and angle for subsequent component installation and positioning. The mounting seat 33 at the front end of the top of the support arm 32 is used to fix the second electric push rod 34. After the second electric push rod 34 is started, its output end can drive the first motor 35 installed through the mounting seat 33 to move up and down, thereby precisely adjusting the height of the polishing wheel 36 to adapt to the polishing requirements of steel plates of different thicknesses. After the first motor 35 is powered on, the polishing wheel 36, which is bolted to its output end, rotates at high speed to polish the surface of the steel plate 26 to be polished. The entire polishing mechanism 3, through the coordinated cooperation of various components, ensures that the polishing wheel 36 can stably and accurately polish the steel plate.

[0027] refer to Figures 3-4The clamping assembly 24 includes a fixing block 241, which is fixedly installed at the output end of the second electric push rod 34. A clamping plate 242 is fixedly installed on the inner side of the fixing block 241, and a receiving plate 243 is fixedly installed on the lower inner side of the clamping plate 242. The combined shape of the receiving plate 243 and the clamping plate 242 is L-shaped. The L-shaped combination of the receiving plate 243 and the clamping plate 242 can better support and clamp the steel plate 26 to be polished. A drive assembly 244 is fixedly connected to the inner side of the receiving plate 243. The drive assembly 244 includes a top plate 2441 and side plates 2442. The top plates 2441 are arranged linearly at equal intervals. The clamping assembly 24 is fixedly installed on the top of the clamping plate 242. Side plates 2442 are fixedly installed at both ends of the clamping plate 242. A second motor 2443 is fixedly installed on the rear side of the side plates 2442. The output end of the second motor 2443 passes through the side plates 2442 and is fixedly installed with a worm gear 2444. Worm wheels 2445 are rotatably connected to the top of the top plate 2441, and the worm wheels 2445 and worm gear 2444 are connected in a transmission connection. Drive rollers 2446 are rotatably connected to the bottom of the top plate 2441, and the top of the drive rollers 2446 is fixedly connected to the bottom of the worm gear 2444. In this grinding device, the clamping assembly 24 and the drive assembly 244 work together to achieve… The clamping and displacement adjustment of the steel plate: When the steel plate needs to be operated, the second electric push rod 34 pushes the fixed block 241 to move, causing the L-shaped structure formed by the clamping plate 242 and the receiving plate 243 connected to it to approach the steel plate and clamp and fix the steel plate. At this time, the drive group 244 plays a role, and the second motor 2443 on the rear side of the side plate 2442 starts. Its output end drives the worm gear 2444 to rotate. Since the worm wheel 2445 is connected to the worm gear 2444, the rotation of the worm gear 2444 will drive the worm wheel 2445 to rotate synchronously. And because the bottom of the worm wheel 2445 is fixedly connected to the top of the drive roller 2446, The rotation of the worm gear 2445 drives the drive roller 2446 to rotate. The rotating drive roller 2446 is in close contact with both sides of the steel plate. Through friction, the steel plate 26 to be polished moves along the front and back direction on the receiving plate 243, completing the position adjustment. At the same time, the top plate 2441 is linearly arranged at equal intervals and fixed to the top of the clamping plate 242, providing stable installation support for components such as the worm gear 2445 and the drive roller 2446. This ensures that the positions of each component are fixed during the operation of the drive assembly 244, and that the drive roller 2446 can stably and continuously apply force to the steel plate when it rotates, achieving precise front and back displacement adjustment of the steel plate.

[0028] refer to Figures 3-4The support assembly 25 includes a support base 251, which is fixedly installed at the middle of both ends of the top of the base plate 1. A support plate 252 is fixedly installed on the top of the support base 251. Movable grooves 253 are provided on both sides of the top of the support plate 252. Support blocks 254 are slidably connected inside the movable grooves 253. The top of the support blocks 254 is fixedly connected to the bottom of the receiving plate 243. The internal cavity of the movable grooves 253 and the side shape of the support blocks 254 are both convex. Rollers are rotatably connected at equal intervals on the top of the receiving plate 243. The steel plate 26 to be polished is placed on top of the receiving plate 243, and the two sides of the steel plate 26 to be polished are attached to the inner side of the drive roller 2446. During the operation of this polishing device, the support assembly 25 works in conjunction with other components to ensure the stability of the steel plate processing. The support base 251 is fixed at the middle of the top two ends of the base plate 1, providing the installation foundation for the entire support assembly 25. The support plate 252 above it has movable grooves 253 on both sides of the top, and the internal sliding connection is a support block 254 with a convex shape on the side. This convex structure design not only... The movement direction of the support block 254 within the movable groove 253 is restricted, allowing it to slide only along the extension direction of the groove, while also preventing the support block 254 from detaching from the movable groove 253, thus ensuring structural stability. The top of the support block 254 is fixedly connected to the bottom of the receiving plate 243. When the receiving plate 243 moves the steel plate 26 to be polished back and forth under the action of the drive group 244, or moves left and right under the action of the first electric push rod 23 of the clamping mechanism 2, the support block 254 can slide synchronously within the movable groove 253, providing support for the receiving plate 243. The support plate 243 provides stable support and guidance, preventing it from shifting or wobbling during movement. Meanwhile, the ball bearings 255, which are rotatably connected at equal intervals on the top of the support plate 243, reduce the friction with the bottom of the steel plate 26 to be polished, making the steel plate move more smoothly on the support plate 243. The two sides of the steel plate 26 to be polished are in contact with the inner side of the drive roller 2446, and the friction generated when the drive roller 2446 rotates can effectively drive the steel plate to move. The support component 25 provides a stable support foundation for this process, ensuring the smooth progress of the polishing operation.

[0029] Operating principle and advantages: When using this high-efficiency polishing device for steel cabinet panels, firstly, the device is installed and fixed in a suitable working position through the countersunk holes at the four corners of the base plate 1. Next, the steel plate 26 to be polished is placed on the receiving plate 243, with the bottom of the steel plate contacting the ball bearings 255 on the top of the receiving plate 243, which reduces friction when the steel plate moves. Then, the clamping mechanism 2 is activated, and the first electric push rods 23 on the two side fixing frames 22 begin to work. When it is necessary to adjust the left and right position of the steel plate 26 to be polished, the first electric push rods 23 on both sides perform different actions: one side of the first electric push rod 23 extends, and the other side of the first electric push rod 23 retracts. This causes the clamping assembly 24 to move laterally, which in turn pushes the steel plate 26 to be polished, held on the inner side, to move left and right, thus adjusting the position of the steel plate in the horizontal dimension. At the same time, the L-shaped structure formed by the clamping plate 242 and the receiving plate 243 gradually approaches the steel plate 26 to be polished. At this time, the inner side of the drive roller 2446 is in contact with the two sides of the steel plate 26 to be polished, and the balls 255 on the receiving plate 243 are in contact with the bottom of the steel plate 26 to be polished, thus achieving the initial positioning of the steel plate. After positioning is completed, the drive assembly 244 begins to function, the second motor 2443 starts, and its output end drives the worm gear 2444 to rotate. Since the worm wheel 2445 and the worm gear 2444 are in contact, the worm gear 2445 rotates. The 444 transmission connection drives the worm gear 2445 to rotate, and the drive roller 2446, which is fixedly connected to the bottom of the worm gear 2445, rotates accordingly. The rotating drive roller 2446 contacts both sides of the steel plate 26 to be polished and generates friction. Under the action of friction, the steel plate 26 to be polished can move in the front-back direction on the receiving plate 243 to achieve position adjustment. At the same time, the support block 254 in the support assembly 25 slides in the movable groove 253 of the support plate 252, which supports and guides the receiving plate 243, ensuring the stability of the steel plate when the receiving plate 243 moves. After completing the positioning and position adjustment of the steel plate 26 to be polished in the left-right and front-back directions, When the polishing mechanism 3 is started, the second electric push rod 34 on the fixed seat 21 at the top front end of the support arm 32 pushes the first motor 35 and the polishing wheel 36 connected to it to move downwards, adjusting the polishing wheel 36 to a suitable polishing height. Then, the first motor 35 starts, driving the polishing wheel 36 to rotate at high speed, and polishing the steel plate 26 to be polished placed on the receiving plate 243. During the polishing process, if it is necessary to polish different parts of the steel plate, the front and back positions of the steel plate can be adjusted again by the drive group 244, or the left and right positions of the steel plate can be adjusted by the coordinated action of the first electric push rods 23 on both sides, so that the polishing wheel 36 can polish the surface of the steel plate comprehensively and evenly.

[0030] The left-right displacement adjustment function of the first electric push rod 23 in this device offers significant advantages. From the perspective of steel plate positioning adjustment, this function enables the steel plate to have bidirectional adjustment capability on the horizontal plane. Not only can it move back and forth via the drive group 244, but it can also move left and right via the first electric push rod 23, greatly improving the flexibility and accuracy of steel plate positioning. Compared with the single fixed or unidirectional adjustment method of traditional grinding devices, this design can meet more complex and diverse grinding needs. Whether for steel plates of different shapes or grinding requirements of specific positions, the polishing can be ensured by flexibly adjusting the position of the steel plate. The polishing wheel 36 accurately covers the area to be polished. In terms of polishing efficiency and quality, the bidirectional adjustment function of this device reduces the operation steps and time costs of manually adjusting the position of the steel plate. Operators do not need to frequently disassemble and reinstall the steel plate to adjust its position. The position can be changed directly through the control of the electric push rod, which speeds up the entire polishing process and improves work efficiency. At the same time, the precise position adjustment ensures that the polishing wheel 36 and the surface of the steel plate always maintain the best contact state, avoiding problems such as uneven polishing and unpolished areas caused by steel plate position deviation, further improving polishing quality and surface finish.

[0031] During the application of this device, the motor drive module specifically uses the L298N driver board, which operates at a voltage range of 7-46V and can provide a continuous current of 2A and a peak current of 4A. It features motor forward and reverse rotation control and PWM speed regulation. The control module uses the Arduino Uno development board, which operates at 5V and has an input voltage of 7-12V. It has 14 digital input / output pins and 6 analog input pins, and can output control signals through programming. The electronic components are powered by a 220V to 12V, 30W power adapter to convert AC to DC power to power the Arduino Uno development board and the L298N driver board. The digital output pins of the development board are connected to the control signal input pins of the L298N driver board to transmit motor start / stop, direction, and speed control signals. The output of the L298N driver board is connected to the first electric actuator 23, the second electric actuator 34, the first motor 35, and the second motor 2443 to drive and control each motor. The controller, namely the Arduino Uno development board, is installed in a waterproof and dustproof control box independently set on the back of the baseboard 1. The box is equipped with DIN rails for fixing the development board and has reserved wiring holes to facilitate the entry and exit of wires. This effectively protects electronic components from dust and iron filings in the processing environment and facilitates the operator to maintain and update the controller later.
