[0025] A second through hole 21 is opened in the middle of the turntable 20 , and a second groove 22 and a third groove 23 are symmetrically arranged on both sides of the second through hole 21 . The second groove 22 and the third groove 23 are both arranged in an L shape, and baffles 231 are arranged in both.

[0026] The positioning mechanism 30 may include two transverse rods 31 , two longitudinal rods 32 , a clamping driving member 33 and a feeding driving member 34 .

[0027] Among them, the two horizontal bars 31 and the two vertical bars 32 are arranged side by side, and the two horizontal bars 31 and the two vertical bars 32 are symmetrically arranged in a well shape. A horizontal rotating cylinder 311 is arranged on the outside of the horizontal bar 31, and a vertical rotating cylinder 321 is arranged on the outside of the vertical bar 32. The horizontal rotating cylinder 311 and the vertical rotating cylinder 321 respectively penetrate the corresponding baffle 231.

[0028] The clamping driving member 33 is disposed in the second groove 22 , and the clamping driving member 33 is connected to the two cross bars 31 and the two longitudinal bars 32 respectively.

[0029] It should be noted that the clamping drive 33 described in this embodiment can simultaneously drive the relative (close / far) movement of the two horizontal bars 31 and the relative (close / far) movement of the two longitudinal bars 32, so as to synchronously control the movement of the two horizontal rotating cylinders 311 and the two longitudinal rotating cylinders 321, and then adjust the length and width of the rectangular space inside the two horizontal rotating cylinders 311 and the two longitudinal rotating cylinders 321, and realize the clamping and positioning function of the workpiece.

[0030] The feeding driving member 34 is disposed in the third groove 23 , and the clamping driving member 33 is connected to the two transverse rotating drums 311 and the two longitudinal rotating drums 321 respectively.

[0031] It should be noted that the feed drive 34 described in this embodiment can control the rotation of the two horizontal rotating drums 311 and the two longitudinal rotating drums 321, so as to adjust the feed amount of the workpiece, and then can flexibly position and adjust the feed of the workpiece in a limited space without the need to move the positioning device as a whole, thereby providing greater flexibility and convenience and improving the efficiency and accuracy of laser cutting processing.

[0032] Specifically, in the actual process of positioning the laser cutting workpiece, the relevant personnel first pass the workpiece horizontally through the inner side of the two horizontal bars 31 and the two longitudinal bars 32, and then simultaneously drive the relative (close / far) movement of the two horizontal bars 31 and the relative (close / far) movement of the two longitudinal bars 32 through the clamping drive 33, so as to synchronously control the movement of the two horizontal rotating drums 311 and the two longitudinal rotating drums 321, and clamp and position the workpiece.

[0033] When it is necessary to adjust the feed amount of the workpiece, the relevant personnel can synchronously control the rotation of the two transverse rotating drums 311 and the two longitudinal rotating drums 321 through the feed drive 34. The rotation of the two transverse rotating drums 311 and the two longitudinal rotating drums 321 can drive the workpiece to move, thereby adjusting the feed amount of the workpiece, and then the workpiece can be flexibly positioned and the feed adjusted in a limited space without the need to move the positioning device as a whole, which provides greater flexibility and convenience and improves the efficiency and accuracy of laser cutting processing.

[0034] When the workpiece needs to be rotated, the fourth driving component 1211 is started, so that the fourth driving component 1211 drives the worm wheel 241 to rotate through the worm 121, thereby realizing the rotation adjustment of the turntable 20.

[0035] In one embodiment of the present invention, Figure 3-Figure 4 As shown, the clamping drive member 33 may include two screw rods 331 , a first drive component 332 and two bevel gear sets 333 .

[0036] The two screw rods 331 are perpendicular to each other, and the screw rods 331 are movably arranged in the second groove 22. The thread directions of the symmetrical two sides of the screw rods 331 are opposite. The two cross bars 31 and the two longitudinal bars 32 are respectively connected to the corresponding screw rods 331. The first driving component 332 is connected to one of the screw rods 331. The two bevel gear sets 333 are respectively connected to the corresponding screw rods 331, and the two bevel gear sets 333 are connected to each other through a connecting shaft 334.

[0037] The bevel gear set 333 includes two meshing bevel gears, and the two bevel gears are connected to the screw rod 331 and the connecting shaft 334 respectively.

[0038] It should be noted that the first driving component 332 described in this embodiment can be a reduction motor, a servo motor, etc. The first driving component 332 can drive the screw 331 connected thereto to rotate. When the screw 331 rotates, it can rotate through the bevel gear set 333 connected thereto. The bevel gear set 333 drives another bevel gear set 333 to operate through the connecting shaft 334, thereby realizing the synchronous rotation adjustment of the two screws 331.

[0039] Specifically, when it is necessary to position the workpiece through the clamping drive member 33, the relevant personnel start the first drive member 332, so that the first drive member 332 drives the screw 331 connected thereto to rotate, and when the screw 331 rotates, it can rotate through the bevel gear set 333 connected thereto, and the bevel gear set 333 drives another bevel gear set 333 to run through the connecting shaft 334, thereby realizing the synchronous rotation adjustment of the two screws 331. During the rotation of the screw 331, the two cross bars 31 and the two longitudinal bars 32 can move synchronously relative to each other, thereby realizing the positioning of the workpiece.

[0040] As a possible situation, a first driving component 332 can be provided on both screw rods 331, so that the two first driving components 332 can respectively drive the screw rods 331 connected thereto, and the bevel gear set 333 can be removed, thereby realizing the separate control of the two cross bars 31 and the separate control of the two longitudinal bars 32, so that rectangles of unequal lengths and widths can be clamped, positioned and transported.

[0041] In one embodiment of the present invention, Figure 2-Figure 4 As shown, the feeding driving member 34 may include two adjusting members 341 respectively connected to the two transverse rotating drums 311 and the two longitudinal rotating drums 321 .

[0042] The adjusting member 341 may include two driven rollers 3411, a synchronous belt 3412, a second driving component 3413 and a driving roller 3414, wherein the two driven rollers 3411 are respectively connected to the corresponding transverse rotating drum 311 or the longitudinal rotating drum 321. The synchronous belt 3412 is arranged outside the driving roller 3414 and the two driven rollers 3411. The second driving component 3413 is movably arranged in the third groove 23 through the third driving component, and the output end of the second driving component 3413 is connected to the driving roller 3414.

[0043] It should be noted that the second driving component 3413 described in this embodiment can be a reduction motor, a servo motor, etc. The second driving component 3413 can drive the driving roller 3414 to rotate, so that the driving roller 3414 drives the two driven rollers 3411 to rotate through the synchronous belt 3412, thereby realizing the rotation adjustment of the two horizontal rotating drums 311 or the two longitudinal rotating drums 321.

[0044] It should be noted that the third driving component described in this embodiment may be a gas rod, a telescopic motor, etc. The third driving component can drive the second driving component 3413 and the driving roller 3414 connected thereto to move horizontally and linearly.

[0045] It can be understood that when the two transverse rotating drums 311 move relative to each other, the second driving component 3413 and the driving roller 3414 can be controlled by the third driving component to move horizontally linearly, thereby ensuring the tension of the synchronous belt 3412, so that the synchronous belt 3412 can smoothly adjust the synchronous rotation of the driving roller 3414 and the two driven rollers 3411 connected thereto. Similarly, when the two longitudinal rotating drums 321 move relative to each other, the adjusting parts 341 thereon are the same as above.

[0046] Specifically, when it is necessary to adjust the feed amount of the workpiece through the feed drive 34, the relevant personnel start the second drive component 3413, so that the second drive component 3413 drives the driving roller 3414 to rotate, and the driving roller 3414 drives the two driven rollers 3411 to rotate through the synchronous belt 3412, thereby realizing the rotation adjustment of the two transverse rotating drums 311 or the two longitudinal rotating drums 321.

[0047] In summary, the laser cutting workpiece positioning device of the embodiment of the utility model can respectively realize the positioning and feed amount adjustment of the workpiece through the linear movement and self-rotational movement of the transverse rotating drum and the longitudinal rotating drum, so that the positioning and feed adjustment of the workpiece can be flexibly performed in a limited space without the need to move the positioning device as a whole, providing greater flexibility and convenience, and improving the efficiency and accuracy of laser cutting processing.
