Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0026] like Figure 1 and Figure 2As shown, an automated grinding device for connecting rubber sheets of high-speed railway carriages comprises a frame 100, a conveying unit 200 for conveying a plurality of rubber sheets is arranged on the top of the frame 100, two grinding units 300 and two driving units 400 for driving the grinding units 300 to move are arranged above the frame 100, the two grinding units 300 are respectively a coarse grinding unit and a fine grinding unit along the conveying direction of the rubber sheets, the conveying unit 200 can clamp and convey a plurality of rubber sheets at one time, the two grinding units 300 are respectively coarse and fine grinding, and the driving unit 400 can flexibly control the grinding units 300, thereby realizing a fully automated process for grinding the rubber sheets and greatly improving the production efficiency.

[0027] like Figure 3 As shown, the conveying unit 200 includes a workbench 201, on which a plurality of transmission rods 202 are arranged. The transmission rods 202 are key components for power transmission. Three sprockets 203 are arranged on the transmission rods 202. Chains 204 are meshed and connected to the plurality of sprockets 203 to form a stable transmission chain system. An actuator for driving the transmission rods 202 to rotate is arranged in the frame 100, wherein the actuator adopts a power source such as a motor. At least three groups of clamps are arranged on the three chains 204, and the clamps are used to firmly fix the rubber sheet to prevent displacement or shaking during the conveying and grinding process.

[0028] like Figure 4 As shown, the clamping member includes two carrying boxes 205, the inner walls of the carrying boxes 205 are rotatably connected with double-threaded screws 206, and two movable plates 207 are threadedly connected to the double-threaded screws 206. The movable plates 207 extend out of the carrying boxes 205 and are provided with clamping seats 208. The clamping seats 208 are used to directly contact and clamp the rubber plates. One end of the double-threaded screws 206 extends out of the carrying boxes 205 and is provided with a driving slot 209. By rotating the double-threaded screws 206, the two movable plates 207 can be moved toward or away from each other.

[0029] Furthermore, in order to realize the driving of the double-threaded screw 206, one side of the upper surface of the workbench 201 is slidably connected with multiple moving seats 211 through multiple slide rails 210, and a connecting plate 212 is arranged between two adjacent moving seats 211. The workbench 201 is provided with two cylinders 213 for driving the connecting plates 212, and the moving seat 211 is provided with a motor 214. The output shaft of the motor 214 is provided with a driving column 215 corresponding to the driving groove 209. When the cylinder 213 is working, it pushes the connecting plate 212 to move, thereby driving the moving seat 211 to slide along the slide rail 210, and the driving column 215 is inserted into the driving groove 209 and drives the double-threaded screw 206 to rotate, thereby realizing the clamping or loosening operation of the clamping seat 208 on the rubber sheet.

[0030] Furthermore, a stabilizing seat 217 is slidably connected to the other side of the upper surface of the workbench 201 via two slide rails 216. A cylinder 219 is provided on the workbench 201 for driving the two stabilizing seats 217 to move. The stabilizing seat 217 is provided with two notches 218 corresponding to the carrying box 205. When the rubber sheet is polished, the cylinder 219 drives the stabilizing seat 217 to move so that its notch 218 clamps the carrying box 205.

[0031] It should be noted that when installing the conveying unit 200, the transmission rod 202 is installed on the workbench 201 to ensure the meshing accuracy between the sprockets 203, the chain 204 is installed and its tension is adjusted so that the chain 204 can be transmitted smoothly, then the clamping parts are installed, the carrying box 205 is fixed on the chain 204, the double-threaded screw 206, the movable plate 207 and the clamping seat 208 are installed to ensure that the double-threaded screw 206 can rotate flexibly and the clamping seat 208 can accurately clamp the rubber plate, then, the relevant components for driving the double-threaded screw 206 are installed, including the movable seat 211, the connecting plate 212, the cylinder 213, the motor 214 and the driving column 215, and the linkage effect is debugged to ensure that the cylinder 213 can push the motor 214 to accurately drive the double-threaded screw 206, and finally, the stabilizing seat 217 and its driving cylinder 219 are installed to debug the matching accuracy of the stabilizing seat 217 and the carrying box 205.

[0032] like Figure 5 As shown, the driving unit 400 includes two moving blocks 401, one of which is threadedly connected to a threaded screw 402, and a second motor 403 is arranged at the end of the threaded screw 402. The second motor 403 is connected to the frame 100, and the threaded screw 402 is driven to rotate by the second motor 403, so as to drive the moving block 401 to move along the axial direction of the screw, thereby adjusting the lateral position of the grinding unit 300. A gantry 404 is arranged on the two moving blocks 401, and two lifting blocks 405 are arranged on the gantry 404, and two lifting blocks 405 are respectively driven to move the two lifting blocks 405. The two cylinders 406 that move the lifting block 405 up and down can accurately control the height of the grinding unit 300 through the cylinder 406 to adapt to rubber plates of different thicknesses. A linear motor 407 is arranged between the two lifting blocks 405. A mounting seat 408 connected to the grinding unit 300 is arranged on the mover seat of the linear motor 407. The linear motor 407 can realize high-speed and accurate longitudinal movement of the grinding unit 300, and cooperate with motion control in other directions, so that the grinding unit 300 can grind the rubber plate in all directions.

[0033] The working process of this embodiment is as follows: the rubber sheet to be polished is placed near the clamping part of the conveying unit 200, and the cylinder 1 213 is started to insert the driving column 215 of the motor 1 214 into the driving groove 209 of the double-threaded screw 206 in the carrying box 205. The motor 1 214 drives the double-threaded screw 206 to rotate, so that the clamping seat 208 clamps the rubber sheet. When the rubber sheet reaches the rough polishing unit position, the cylinder 219 is started, and the cylinder 219 drives the stabilizing seat 217 to move so that the notch 218 of the stabilizing seat 217 is clamped to the carrying box 205. Then, according to the relevant data of the thickness of the rubber sheet, the driving unit 400 is started to polish the unit 3. 00 moves to the designated position and starts rough grinding of the rubber sheet. After the rough grinding is completed, the driving groove 209 and the driving column 215 as well as the notch 218 on the stabilizing seat 217 are separated from the carrying box 205, and then the rubber sheet continues to be transported to the fine grinding unit. The notch 218 on the stabilizing seat 217 and the driving column 215 at the fine grinding unit are again inserted into the carrying box 205 and the driving groove 209 respectively for fine grinding to remove the minor defects left by the rough grinding and improve the surface smoothness of the rubber sheet. After the grinding is completed, the driving column 215 rotates to release the clamping work on the rubber sheet, and the staff unloads the rubber sheet.
