[0028] See also Figure 1-7As shown, the utility model relates to an automatic positioning and limiting mechanism for the side of a plate roll, which is mainly used on the cutting machine workbench 5 of a plate roll laser cutting machine. The automatic positioning and limiting mechanism for the side of the plate roll includes a drive assembly 1, a transmission assembly 2, several groups of positioning movable assemblies 3, and several groups of positioning fixed assemblies 4. Several groups of the positioning movable assemblies 3 and the drive assembly 1 are arranged on one side of the cutting workbench 5, and several groups of the positioning fixed assemblies 4 are arranged on the other side of the cutting workbench 5. The drive assembly 1 is connected to the positioning movable assembly 3 through the transmission assembly 2. The drive assembly 1 drives the positioning movable assembly 3 to perform linear reciprocating motion toward the positioning fixed assembly 4 through the transmission assembly 2, thereby adjusting the distance between the positioning movable assembly 3 and the positioning fixed assembly 4.

[0029] The rolled plate is unfolded by the leveling machine to form a plate. When the plate enters the table of the cutting machine workbench 5, the driving component 1 drives the positioning movable component 3 to move linearly through the transmission component 2. The positioning movable component 3 will push the plate toward the positioning fixed component 4, thereby realizing the positioning of the plate and limiting the position of the plate.

[0030] In this embodiment, the drive assembly 1 is installed on one side of the cutting machine workbench 5. Furthermore, the drive assembly 1 includes a servo motor 11, a reducer 12, a first reducer mounting plate 13, and a second reducer mounting plate 14. The servo motor 11 is connected and installed with the reducer 12. The first reducer mounting plate 13 is fixedly mounted on one side of the cutting machine workbench 5. The left and right sides of the second reducer mounting plate 14 are fixedly mounted on the first reducer mounting plate 13.

[0031] In this embodiment, the transmission assembly 2 includes a plurality of synchronous belts 21 and a plurality of synchronous pulleys 22. The output end 121 of the reducer 12 is provided with a driving pulley 24. Each set of positioning movable assemblies 3 is connected to the synchronous pulley 22. The output end 121 of the reducer 12 is connected to the synchronous pulley 22 of the positioning movable assembly 3 adjacent to the reducer 12 via the synchronous belt 21. The synchronous pulleys 22 of each set of adjacent positioning movable assemblies 3 are connected via the synchronous belt 21, thereby enabling the drive assembly 1 to drive the plurality of positioning movable assemblies 3 to perform synchronous motion. A tensioning pulley 23 is provided within the synchronous belt 21. The tensioning pulley 23 tightens the synchronous belt 21 to ensure the tension of the synchronous belt 21 and to ensure close contact between the synchronous belt 21 and the synchronous pulley 22.

[0032] In this embodiment, the positioning movable assembly 3 includes a movable portion 31 and a positioning portion 32 . The positioning portion 32 is slidably mounted on the movable portion 31 . The movable portion 31 drives the positioning portion 32 to perform linear reciprocating motion toward the positioning fixed assembly 4 .

[0033] The movable portion 31 includes a guide rail mounting frame 313, a screw 314, a screw nut 315, a guide rail 316, a positioning drive 317, a first bearing seat 318, and a second bearing seat 319. The fixed bearing seat 311 is mounted on one side of the cutting machine workbench 5 via a bearing seat fixing plate 312. One end of the screw 314 passes through the fixed bearing seat 311 and connects to the synchronous wheel 22. The guide rail mounting frame 313 is fixed to the cutting machine workbench 5 and is provided with a guide rail 316. The guide rail 316 has a first bearing seat 318 and a second bearing seat 319 at its front and rear ends. The other end of the screw 314 is mounted within the first bearing seat 318 and the second bearing seat 319. The screw rod 314 has screw threads, the screw nut 315 is mounted on the screw threads, and the positioning driver 317 has a slider 3171. The positioning driver 317 is fixedly mounted on the screw nut 315, and the slider 3171 is engaged with the guide rail 316. When the screw rod 314 rotates, the screw nut 315 engages with the screw rod 314 threads, causing the screw nut 315 to drive the positioning driver 317 to perform linear reciprocating motion along the guide rail 316.

[0034] The positioning portion 32 includes a first cylinder fixing member 321, a second cylinder fixing member 322, a third cylinder fixing member 323, a first cylinder 324, a movable positioning plate 325, and a movable positioning wheel 326.

The first cylinder 324 is mounted on the third cylinder fixing member 323, the movable positioning plate 325 is mounted on the first piston rod 3241 of the first cylinder 324, and the movable positioning wheel 326 is mounted on the movable positioning plate 325. The present invention controls the extension and contraction of the first piston rod 3241 of the first cylinder 324, thereby driving the movable positioning plate 325 outward, and the movable positioning wheel 326 pushes the plate, causing the plate to rest against the positioning and fixing assembly 4. When the width between each set of positioning movable components 3 is smaller than the width of the plate, the first cylinder 324 can act as a buffer. Furthermore, during laser cutting, when the cutting head reaches the position of the movable positioning wheel 326, the first cylinder 324 can be controlled to retract the movable positioning wheel 326 to avoid the cut, thereby facilitating the operation.

[0035] In this embodiment, the positioning and fixing assembly 4 includes a positioning and fixing bracket 41, a fourth cylinder fixing member 42, a second cylinder 43, a fixed positioning plate 44, and a fixed positioning wheel 45. The positioning and fixing bracket 41 is fixedly mounted on the cutting machine workbench 5, the fourth cylinder fixing member 42 is mounted on the positioning and fixing bracket 41, the second cylinder 43 is disposed on the fourth cylinder fixing member 42, the fixed positioning plate 44 is mounted on the second piston rod 431 of the second cylinder 43, and the fixed positioning wheel 45 is mounted on the fixed positioning plate 44. The present invention controls the extension and retraction of the second piston rod 431 of the second cylinder 43 to drive the fixed positioning plate 44 outward, thereby causing the fixed positioning wheel 45 to limit the position of the plate.

[0036] The following is an implementation method of the present invention: After the plate enters the table 5 of the cutting machine, the plate advances with the fixed positioning wheel 45 of the positioning and fixing assembly 4 as the initial edge reference. When the plate is conveyed to the length required for processing on the cutting machine table 5, the driving assembly 1 rotates the screw 314 seat of the positioning movable assembly 3 through the transmission assembly 2. The screw nut 315 drives the positioning drive 317 to perform linear reciprocating motion along the guide rail 316, so that the movable positioning wheel 326 of the positioning part 32 pushes the plate to the fixed positioning wheel 45 of the positioning and fixing assembly 4 for limiting. When the plate is limited, the laser cutting machine performs cutting processing. In the above process, each of the first cylinder 324 and the second cylinder 43 can be controlled by a separate solenoid valve.

[0037] This utility model relates to an automatic positioning and limiting mechanism for the side edge of a rolled plate. In this mechanism, a drive assembly 1 drives a transmission assembly 2, which causes a positioning movable assembly 3 to push a plate, pushing the plate to a positioning and fixing assembly 4 for positioning, thereby preventing deviations in cutting dimensions caused by plate deviation. Because the plate is positioned and limited using the positioning wheels of the positioning and fixing assembly 4 as a reference, the plate's positional accuracy is guaranteed, thereby improving the cutting accuracy of each plate and ensuring product quality requirements.

[0038] The above embodiments are merely descriptions of preferred embodiments of the present invention and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering technicians in this field should fall within the scope of protection determined by the claims of the present invention.
