[0020] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0021] The metal sign surface polishing apparatus of this application embodiment will now be described with reference to the accompanying drawings.

[0022] As shown in Figures 1-5, the metal sign surface polishing device of this application embodiment may include a mounting frame 1, a clamping drive mechanism 2, an adjusting grinding mechanism 3, a fixing mechanism 4, a grinding drive mechanism 5, and a polishing wheel 6.

[0023] It should be noted that the mounting bracket 1 described in the above embodiment has a bottom frame installed at its bottom end to increase the height of the polishing device.

[0024] The clamping drive mechanism 2 is mounted on the mounting bracket 1.

[0025] Understandably, the clamping drive mechanism 2 completes the fixing and turning of the sign.

[0026] The adjusting grinding mechanism 3 is located inside the mounting bracket 1. The adjusting grinding mechanism 3 may include a linkage component 31, a moving component 32, and a speed conversion component 33.

[0027] It should be noted that the linkage component 31 described in the above embodiments is provided in two sets.

[0028] As one possible approach, an electric push rod can be installed on the movable component 32 to adjust the position of the linkage component 31, thereby completing the cyclic polishing of the fixed sign.

[0029] The linkage component 31 and the moving component 32 are respectively mounted on the mounting frame 1, and the linkage component 31 is slidably mounted on the moving component 32. The speed conversion component 33 is connected to the moving component 32, and the speed conversion component 33 is connected to the linkage component 31 in a transmission manner.

[0030] As one possible approach, an electric push rod can be installed at the bottom of the linkage component 31 to adjust the position of the polishing wheel 6 and bring it into contact with the sign to achieve the polishing of the sign.

[0031] It should be noted that a rotation count metering device can be installed on the speed conversion component 33 to measure the number of rotations of the speed conversion component 33, thereby increasing the rotation count range of the linkage component 31.

[0032] Specifically, the installation of the speed conversion component 33 is completed under the action of the linkage component 31, and then the position of the linkage component 31 and the speed conversion component 33 is adjusted by the moving component 32, thereby realizing the grinding work of different positions on the fixed nameplate.

[0033] The fixing mechanism 4 is mounted on the mounting bracket 1.

[0034] Understandably, the fixing mechanism 4 is used to further fix the sign.

[0035] The grinding drive mechanism 5 may include a grinding motor 51 and a transmission assembly 52.

[0036] It should be noted that the grinding motor 51 described in the above embodiments is mounted on the moving component 32 by a fixing bracket.

[0037] The grinding motor 51 and the transmission assembly 52 are respectively mounted on the moving assembly 32, and the grinding motor 51 is connected to the linkage assembly 31 through the transmission assembly 52.

[0038] Specifically, driven by the grinding motor 51, the transmission component 52 rotates on the linkage component 31, and the rotation of the two linkage components 31 drives the polishing wheel 6 to complete the grinding work on the fixed sign.

[0039] Polishing wheel 6 is mounted on linkage assembly 31.

[0040] It should be noted that polishing wheels with different grit sizes can be replaced according to actual needs.

[0041] Specifically, the metal sign surface polishing device provided in this application can not only be used for grinding and polishing signs, but also for cleaning burrs on the surface of sheet metal. In actual operation, the relevant personnel place the sign to be polished inside the mounting frame 1, and then use the clamping drive mechanism 2 to fix the sign inside the mounting frame 1. Then, the fixing mechanism 4 further fixes the sign on the clamping drive mechanism 2 to prevent the sign from shaking during the grinding and polishing process.

[0042] Subsequently, based on the material of the sign, the speed conversion component 33 is driven to adjust the speed of the linkage component 31. Under the drive of the polishing motor 51, the transmission component 52 drives the linkage component 31 to rotate. Under the rotation of the linkage component 31, the polishing wheel 6 rotates with the linkage component 31. Furthermore, the moving component 32 drives the linkage component 31 to move, thereby achieving polishing of different positions on the sign and completing the polishing work of the sign. After one side of the sign is polished, the clamping drive mechanism 2 drives the polished sign to rotate, thereby flipping the other side of the sign and facing the polishing wheel 6. Then, the polishing steps of the sign are repeated to complete the polishing of the flipped sign.

[0043] Finally, the fixing mechanism 4 releases the sign, and the worker removes the polished sign from the clamping drive mechanism 2, replaces it with the next unprocessed sign, and repeats the processing steps.

[0044] In one embodiment of this application, as shown in Figures 1-2 and 5, the clamping drive mechanism 2 may include a drive assembly 21, a clamping assembly 22, an adapter rod 23, and an adjustment assembly 24.

[0045] It should be noted that the drive assembly 21 described in the above embodiment includes a drive motor and two sets of drive gears. The drive motor is installed on both sides of the mounting bracket 1, and the drive gears are installed on the clamping assembly 22. At the same time, the two sets of drive gears mesh with each other, and under the drive of the drive motor, the two sets of drive gears drive the clamping assembly 22 to rotate, thereby completing the flipping of the fixed sign.

[0046] The drive assembly 21 and the clamping assembly 22 are respectively installed on both sides of the mounting frame 1, and the drive assembly 21 is connected to the clamping assembly 22 in a driving manner. The adjustment assembly 24 is installed on the top of the mounting frame 1, and the adjustment assembly 24 is connected to the clamping assembly 22 in a driving manner through the adapter rod 23.

[0047] Specifically, driven by the adjusting component 24, the adapter rod 23 moves the clamping component 22 to adapt to different sizes of signs. Then, the clamping component 22 fixes the sign inside the mounting frame 1. After the sign is processed, the driving component 21 drives the clamping component 22 to flip, thereby completing the polishing work on the other side of the sign.

[0048] In one embodiment of this application, as shown in Figures 1-2 and 5, the clamping assembly 22 may include a rotating wheel 221, a connecting rod 222, a telescopic rod 223, a cylinder 224, a clamping plate 225, and a mounting box 226.

[0049] It should be noted that the rotating wheel 221, connecting rod 222 and mounting box 226 described in the above embodiment are provided in two sets, while the telescopic rod 223, cylinder 224 and clamping plate 225 are provided in four sets. At the same time, the rotating wheel 221, connecting rod 222 and mounting box 226 are respectively provided with two telescopic rods 223, cylinders 224 and clamping plates 225.

[0050] The rotating wheel 221 is rotatably mounted on both sides of the mounting frame 1. The connecting rod 222 rotatably passes through the rotating wheel 221 and is connected to the adapter rod 23. The telescopic rod 223 is connected to the rotating wheel 221. The mounting box 226 is installed at the extended end of the telescopic rod 223. Two sets of cylinders 224 are provided, and both sets of cylinders 224 are installed inside the mounting box 226. The extended end of the cylinder 224 is connected to the clamping plate 225.

[0051] As a possible solution, a rubber pad can be installed on cylinder 224 to increase the friction between cylinder 224 and the nameplate.

[0052] Specifically, the rotating wheel 221 completes the installation of the clamping plate 225 through the telescopic rod 223 and the mounting box 226. Then, the clamping plate 225 fixes the cylinder 224. Under the drive of the clamping plate 225, the cylinder 224 fixes the sign. At the same time, after the rotating wheel 221 is driven by the drive component 21, the telescopic rod 223 drives the mounting box 226 to fix the clamping plate 225 and the cylinder 224, causing the sign to flip. Since the connecting rod 222 and the rotating wheel 221 are rotating, the rotation of the rotating wheel 221 is not affected by the connecting rod 222.

[0053] In one embodiment of this application, as shown in Figures 1-2 and 5, the adjustment assembly 24 may include an adjustment motor 241, a drive wheel 242, a driven wheel 243, a sleeve 244, and a lead screw 245.

[0054] It should be noted that the sleeve 244 described in the above embodiments is mounted on the mounting bracket 1 by means of a bracket.

[0055] It should be noted that the threads at both ends of the sleeve 244 described in the above embodiment are arranged in opposite directions, and the threads on the two sets of lead screws 245 are matched with the threads at both ends of the sleeve 244.

[0056] The regulating motor 241 is installed on the top of the mounting frame 1. The driving wheel 242 is connected to the output end of the regulating motor 241. The driven wheel 243 is connected to the sleeve 244. The sleeve 244 is rotatably installed on the top of the mounting frame 1. The driving wheel 242 and the driven wheel 243 are connected by belt drive. The lead screw 245 is respectively set at both ends of the sleeve 244. The two sets of lead screws 245 are threaded into the inside of the sleeve 244. The lead screw 245 is rotatably connected to the adapter rod 23.

[0057] Specifically, driven by the adjusting motor 241, the driving wheel 242 drives the driven wheel 243 and the sleeve 244 to rotate via a belt. The rotation of the sleeve 244 drives the lead screw 245 to rotate, thereby adjusting the position of the lead screw 245. When the lead screw 245 rotates, the connection between the adapter rod 23 and the rotating wheel 221 limits the rotation of the lead screw 245. The lead screw 245 adjusts the position of the connecting rod 222 and the mounting box 226 through the adapter rod 23, thereby adapting to signs of different sizes.

[0058] In one embodiment of this application, as shown in Figures 1 and 4, the linkage component 31 may include a rotating disk 311, a rotating ring 312, and an arc plate 313.

[0059] It should be noted that the linkage component 31 described in the above embodiments is provided in two sets.

[0060] It should be noted that each set of rotating disks 311 is provided with four sets of rotating rings 312, and the rotating rings 312 are provided with sliding grooves for the rotating rings 312 to slide.

[0061] The rotating disk 311 is rotatably mounted on the moving component 32, the rotating ring 312 is connected to the arc plate 313, and the arc plate 313 is slidably connected to the rotating disk 311 by a spring.

[0062] Understandably, the connection between the arc plate 313 and the rotating disk 311 is completed under the action of the spring. After the arc plate 313 is squeezed by the speed conversion component 33, it drives the rotating ring 312 to switch on the rotating disk 311, thereby achieving the adjustment of the rotation speed on the rotating disk 311.

[0063] In one embodiment of this application, as shown in Figures 1 and 4, the moving component 32 may include a moving motor 321, a screw 322, and a moving frame 323.

[0064] It should be noted that a limiting plate is installed on the movable frame 323 described in the above embodiment, thereby limiting the movement of the movable frame 323 on the screw 322.

[0065] The movable motor 321 is installed on one side of the mounting frame 1, the screw 322 is rotatably installed on the mounting frame 1, the output end of the movable motor 321 passes through the mounting frame 1 and is connected to the screw 322, and the movable frame 323 is threaded onto the outside of the screw 322.

[0066] Specifically, driven by the moving motor 321, the screw 322 drives the moving frame 323 to move, thereby adjusting the position of the linkage component 31 and achieving polishing of different positions on the nameplate.

[0067] In one embodiment of this application, as shown in FIG4, the speed conversion component 33 may include a rotating gear 331, a drive rod 332, a speed motor 333, a meshing gear 334, and a pressure rod 335.

[0068] It should be noted that the dimensions of the meshing gear 334 and the rotating gear 331 described in the above embodiments are 10-15cm.

[0069] It should be noted that the meshing gear 334 described in the above embodiment is equipped with a limiting threaded post. At the same time, the meshing gear 334, the pressure rod 335 are connected to the limiting threaded post. The limiting threaded post limits the meshing gear 334 and the pressure rod 335 when they rotate. When the meshing gear 334 rotates, the meshing gear 334 and the pressure rod 335 rise, thereby realizing the adjustment of the size of the rotating ring 312.

[0070] Among them, the rotating gear 331 is connected to the output end of the speed motor 333 through the drive rod 332. The speed motor 333 is installed on the top of the moving frame 323. The meshing gear 334 is connected to the pressure rod 335. The rotating gear 331 meshes with the pressure rod 335. The pressure rod 335 is tapered and passes through the rotating disk 311 and abuts against the arc plate 313.

[0071] Specifically, driven by the speed motor 333, the drive rod 332 drives the rotating gear 331 to adjust the height of the meshing gear 334 and the pressure rod 335. Under the action of the limiting threaded column, the meshing gear 334 and the pressure rod 335 rise. During the rising process, the meshing gear 334 is always engaged with the rotating gear 331, which prevents the meshing gear 334 from disengaging from the rotating gear 331.

[0072] In one embodiment of this application, as shown in FIG4, the transmission assembly 52 may include a transmission gear 521, a connecting gear 522, a rotating column 523, and a transmission belt 524.

[0073] It should be noted that the rotating column 523 described in the above embodiments is hollow.

[0074] The transmission gear 521 and the connecting gear 522 are rotatably mounted on the movable frame 323, and the transmission gear 521 meshes with the connecting gear 522. The transmission gear 521 is connected to the output end of the grinding motor 51, and the connecting gear 522 is connected to the rotating column 523. The rotating column 523 is mounted on the bottom end of the rotating disk 311, and the transmission belt 524 is sleeved on the outside of the rotating ring 312.

[0075] Specifically, after the transmission gear 521 is driven by the grinding motor 51, the connecting gear 522 drives the rotating column 523 to rotate. When the rotating column 523 rotates, the transmission belt 524 drives the rotating ring 312 to rotate together. Then the rotating ring 312 drives the rotating disk 311 to rotate, and the rotation of the rotating disk 311 drives the polishing wheel 6 to complete the grinding and polishing of the nameplate.

[0076] In one embodiment of this application, as shown in Figures 1-3, the fixing mechanism 4 may include a lifting assembly 41, a fixing plate 42, and a negative pressure assembly 43.

[0077] It should be noted that the lifting component 41 described in the above embodiments can be a hydraulic cylinder.

[0079] The negative pressure component 43 may include an air extraction component 431, a suction cup 432, and an air tube 433.

[0080] It should be noted that the trachea 433 described in the above embodiments is a telescopic tube.

[0081] It should be noted that multiple sets of suction cups 432 and air tubes 433 are provided in the above embodiments.

[0082] The suction assembly 431 is mounted on the mounting bracket 1, the suction cup 432 is mounted on the fixing plate 42, and the suction cup 432 is connected to the suction assembly 431 through the air pipe 433.

[0083] Specifically, the position of the fixed plate 42 is adjusted by the lifting component 41, and then the suction component 431 uses the air pipe 433 to adsorb the sign placed on the suction cup 432, thereby fixing the sign.

[0084] In summary, the metal sign surface polishing device of this application embodiment can adjust the speed of the polishing device according to actual needs, while eliminating the need for manual adjustment, effectively improving the polishing quality of the sign.
