[0038] The present invention will be specifically described below in conjunction with the attached drawings. As Figures 1-14 shown, a grinding device for hardware processing includes a vehicle frame assembly 1, a grinding assembly 2 and a wheel assembly 3. The vehicle frame assembly 1 includes an upper vehicle frame 11 and a lower vehicle frame 12, and the upper vehicle frame 11 and the lower vehicle frame 12 are arranged in parallel; the wheel assembly 3 is arranged at the left and right ends of the upper vehicle frame 11 and the lower vehicle frame 12, and the grinding assemblies 2 are bolted to the front and rear ends of the upper vehicle frame 11. The wheel assembly 3 arranged at both ends of the vehicle frame assembly 1 drives the entire grinding device to move on the railing. The wheel assembly 3 can move on the surfaces of various railings, and during the movement, the grinding assembly 2 grinds the surface of the railing to prepare for the subsequent painting process of the railing.

[0039] Refer to the attached Figures 2-6 drawing. The grinding assembly 2 includes a connecting plate 21. The connecting plate 21 is L-shaped. The mutually remote sides of the connecting plate 21 are slidably connected to fixing seats 22 up and down. The cross-section of the fixing seat 22 is U-shaped. A plurality of vertically arranged belt pulleys 23 are evenly distributed in the fixing seat 22. The upper and lower ends of the belt pulley 23 are rotatably connected to the fixing seat 22 through bearing seats 26; two parallel belt grooves 231 are arranged on the belt pulley 23, and adjacent belt pulleys 23 are connected by a transmission belt 24. One of the belt pulleys 23 in the middle part penetrates the fixing seat 22 and is connected to the first motor 221 through a coupling. The first motor 221 is fixedly connected to the outside of the fixing seat 22. The first motor 221 drives one of the belt pulleys 23 to rotate, and the rotating belt pulley 23 drives all the belt pulleys 23 to rotate through the transmission belt 24 to realize the transmission of power.

[0040] A grinding disc 25 is coaxially and fixedly connected to the lower end of each belt pulley 23. A plurality of grinding lead screws 251 are evenly distributed on the lower side of the grinding disc 25. The belt pulley 23 drives the grinding disc 25 to rotate, and the grinding lead screws 251 on the lower side of the grinding disc 25 grind and remove rust from the surface of the railing or grind the welding points. The grinding lead screws 251 on the lower side of the grinding disc 25 can be replaced according to the actual situation.

[0041] Further, refer to Figures 2-4 the drawing. One guide rail 211 is vertically arranged at each of the left and right ends of the mutually remote sides of the connecting plate 21. Two sliders 212 are arranged on each guide rail 211, and the fixing seat 22 is bolted to the sliders 212; by arranging two sliders 212 on the guide rail 211, the movement of the fixing seat 22 is made more stable.

[0042] A driving module 213 is arranged between the connecting plate 21 and the fixed seat 22. The driving module 213 is fixedly arranged on the connecting plate 21. The push block 214 of the driving module 213 is bolted to the fixed seat 22. A plurality of limit sensors 215 are arranged on the driving module 213. The transmission mode of the driving module 213 is the transmission of the lead screw nut and the driving motor, which is the prior art. The push block 214 of the driving module 213 drives the fixed seat 22 to move up and down, and the fixed seat 22 drives a plurality of grinding discs 25 to move up and down, so as to polish the surface of the railing.

[0043] Further, referring to Figures 7-8 , three connecting bars 16 are bolted to the lower side of the upper frame 11. One guide rail slider assembly 14 is fixedly arranged on each of the two connecting bars 16. The upper frame 11 is connected to the lower frame 12 through the guide rail slider assembly 14. The sliding connection between the upper frame 11 and the lower frame 12 is realized through the guide rail slider assembly 14. A positioning assembly 15 is fixedly connected to the other connecting bar 16. The positioning assembly 15 realizes the relative positioning between the upper frame 11 and the lower frame 12. The positioning assembly 15 drives the upper frame 11 and the lower frame 12 to move away from or close to each other, controls the distance between the upper frame 11 and the lower frame 12, and realizes the relatively stable sliding between the upper frame 11 and the lower frame 12 through the guide rail slider assembly 14.

[0044] Further, referring to Figure 12 , the positioning assembly 15 includes a bottom plate 151. The bottom plate 151 is fixedly connected to the connecting bar 16 on the lower side of the upper frame 11. A sliding plate 152 is slidably connected to the bottom plate 151. The sliding plate 152 is fixedly connected to the lower frame 12. A servo motor 153 is arranged on the bottom plate 151. The servo motor 153 drives the sliding plate 152 to move. The servo motor 153 drives the sliding plate 152 to move through a lead screw nut structure, which can stably drive the sliding plate 152 to move and fix the position of the sliding plate 152. The sliding plate 152 drives the movement and positioning of the lower frame 12, and realizes the control of the distance between the upper frame 11 and the lower frame 12 and the relative positioning.

[0045] Further, referring to Figure 8 , two electromagnets 13 are bolted to the lower side of the lower frame 12 away from the upper frame 11. Through the magnetic force of the electromagnets 13, the grinding device is adsorbed on the surface of the railing, which is convenient to realize the stable connection between the railing and the grinding device. No matter whether the railing is in a vertical or horizontal state, the grinding device can be stably connected to the railing through the electromagnets 13, improving the use range of the grinding device.

[0046] Further, referring to Figures 9-11, the wheel assembly 3 includes a first wheel group 31, a second wheel group 32, and a third wheel group 33 that are connected in sequence. The first wheel group 31, the second wheel group 32, and the third wheel group 33 are connected by hinges 34, and the relative rotational connection between the first wheel group 31, the second wheel group 32, and the third wheel group 33 is achieved through the hinges 34.

[0047] At both ends of the first wheel group 31 and the third wheel group 33 that are far away from each other, connecting blocks 361 are hinged. The other ends of the connecting blocks 361 are welded with sliding beams 36. The two sliding beams 36 are arranged collinearly and are both slidably connected within the same cross beam 35; the side surface of the cross beam 35 is bolted to the upper frame 11, and the side surface of the second wheel group 32 is bolted to the lower frame 12. Through the relative movement between the upper frame 11 and the lower frame 12, the distance between the second wheel group 32 and the cross beam 35 is controlled, so as to control the first wheel group 31, the second wheel group 32, and the third wheel group 33 to be in the same plane, or form a concave arc surface, or a convex arc surface, as Figure 13 and Figure 14 , to adapt to different railing surface shapes, such as flat railings or arc-shaped railings, and improve the applicable range of the grinding device.

[0048] Furthermore, referring to Figure 11 , the first wheel group 31, the second wheel group 32, and the third wheel group 33 all include wheel seats 37. At both ends of the wheel seat 37, a driving wheel 38 is rotatably connected respectively. A crawler belt 381 is sleeved between the driving wheels 38. Through the arrangement of the crawler belt 381, the grinding device can move on the railing, preventing the wheels of the grinding device from getting stuck in the gaps of the railing and unable to move normally; one of the driving wheels 38 is connected to the second motor 39 through a diaphragm coupling 391, and the second motor 39 is fixedly connected to the outer side surface of the wheel seat 37. By arranging the second motor 39 on the first wheel group 31, the second wheel group 32, and the third wheel group 33, when one of the wheel groups is in a suspended state, the other wheel groups can normally drive the grinding device to move, improving the passability of the grinding device.

[0049] Furthermore, the crawler belt 381 is made of rubber material, and convex blocks are provided on the outer surface of the crawler belt 381 to increase the friction between the crawler belt 381 and the railing and prevent relative sliding between the friction device and the railing.

[0050] Working principle: According to whether the railing to be ground is flat or arc-shaped, the distance between the upper frame 11 and the lower frame 12 is adjusted through the positioning assembly 15, so as to adjust the distance between the second wheel group 32 and the cross beam 35, making the curvature of the arc surface where the first wheel group 31, the second wheel group 32, and the third wheel group 33 are located the same as the curvature of the arc-shaped railing. Place the grinding device on the railing, start the electromagnet 13, and adsorb the grinding device on the railing through the magnetic force of the electromagnet 13 to complete the installation and arrangement of the grinding device.

[0051] Drive the grinding disc 25 to move downward through the drive module 213, so that the grinding lead screw 251 contacts the railing, complete the adjustment of the grinding disc 25, start the first motor 221 to drive the grinding disc 25 to rotate, and at the same time, the wheel assembly 3 drives the grinding device to move forward to grind the railing.

[0052] When the grinding device has finished grinding one area and is about to enter another area, according to the shape and curvature of the other area to be entered, adjust the distance between the upper frame 11 and the lower frame 12 again through the positioning component 15, so as to adjust the distance between the second wheel set 32 and the cross beam 35, make the curvature of the arc surface where the first wheel set 31, the second wheel set 32 and the third wheel set 33 are located the same as the curvature of the arc surface railing, place the grinding device on the railing, start the electromagnet 13, and adsorb the grinding device on the railing through the magnetic force of the electromagnet 13 to complete the installation and arrangement of the grinding device.

[0053] Drive the grinding disc 25 to move downward again through the drive module 213, so that the grinding lead screw 251 contacts the railing, complete the adjustment of the grinding disc 25, start the first motor 221 to drive the grinding disc 25 to rotate, and at the same time, the wheel assembly 3 drives the grinding device to move forward to grind the railing.
