DETAILED DESCRIPTION

[0022] The present invention is further described below in conjunction with specific embodiments. However, people familiar with the art should understand that the detailed description given here in conjunction with the drawings is for better explanation, and the structure of the present invention necessarily exceeds these limited embodiments. For some equivalent replacement schemes or common means, they are no longer described in detail herein, but still fall within the scope of protection of the present application.

[0023] Figures 1 to 5 It is the best embodiment of the utility model, and the following Figures 1 to 5 The utility model is further described.

[0024] A polyurethane board production positioning device includes a workbench 1 and a laser cutting machine 23 for cutting operations. The workbench 1 is equipped with a movable adjustment rod 18, and the adjustment rod 18 is an inverted U-shaped block. The laser cutting machine 23 is connected to the adjustment rod 18 through an electric push rod. The position of the laser cutting machine 23 can be adjusted by the adjustment rod 18, and the upper and lower positions are adjusted by the electric push rod. Electric push rods in different directions can also be installed on the adjustment rod 18 to adjust the left and right positions of the laser cutting machine 23. This is a prior art and will not be described herein. For discussion, auxiliary blocks 2 are fixedly connected to the front and rear sides of the workbench 1, and two U-shaped connecting rods 8 that can move synchronously are arranged on the two auxiliary blocks 2. The U-shaped connecting rod 8 is an inverted U-shaped block. Baffles 9 are fixedly connected to the two U-shaped connecting rods 8, and the bottom of the baffle 9 is in contact with the top of the workbench 1. Since the bottom of the baffle 9 is in contact with the top of the workbench 1, during the movement of the two U-shaped connecting rods 8, the baffle 9 can limit and fix the two polyurethane plates placed on the workbench 1, and a fixing mechanism is arranged on the U-shaped connecting rod 8.

[0025] When in use, the polyurethane plate to be cut is placed on the workbench 1, and then the two U-shaped connecting rods 8 are moved to drive the two baffles 9 to fix the two ends of the polyurethane plate, and then the polyurethane plate is fixed by the fixing mechanism on the two U-shaped connecting rods 8, and finally the laser cutting machine 23 on the adjustment rod 18 is used to cut the polyurethane plate.

[0026] The fixing mechanism includes a connecting plate 10, an electric telescopic rod 11 and a fixing block 12. The two U-shaped connecting rods 8 are internally provided with a connecting plate 10 that can move up and down. The top of the U-shaped connecting rod 8 is fixedly installed with an electric telescopic rod 11. The output end of the electric telescopic rod 11 passes through the interior of the U-shaped connecting rod 8 and is fixedly connected to the corresponding point on the top of the connecting plate 10. The lower wall surface of the connecting plate 10 is fixedly connected with a plurality of fixing blocks 12. The number of the fixing blocks 12 is not limited here and can be installed according to actual usage. The fixing blocks 12 are rectangular elastic blocks, and the two ends of the fixing blocks 12 are bent downward.

[0027] When in use, the electric telescopic rod 11 can be used to control the connection plate 10 to move up and down inside the U-shaped connecting rod 8, and the polyurethane plate can be fixed by the fixing block 12 on the connection plate 10. In combination with the two baffles 9, the left and right and up and down fixation of the polyurethane plate can be completed, thereby ensuring the stability when cutting the polyurethane plate.

[0028] The fixing mechanism also includes an arc-shaped gasket 13, a movable hole 14, a limit rod 15 and a limit ring 16. The two ends of the fixed block 12 are fixedly connected with the arc-shaped gasket 13. The arc-shaped gasket 13 is an arc-shaped elastic block with a smooth surface. Two movable holes 14 are symmetrically provided at the bending positions at both ends of the fixed block 12. The internal movable clamps of the two movable holes 14 are connected with movable limit rods 15. The two ends of the limit rod 15 are located at the positions outside the corresponding movable holes 14 and are fixedly connected with the limit rings 16.

[0029] When the connecting plate 10 drives the fixing block 12 downward to fix the polyurethane plate, first, the arc-shaped gaskets 13 installed at both ends of the fixing block 12 will contact the polyurethane plate, and the arc-shaped gaskets 13 are arc-shaped elastic blocks with smooth surfaces, so the problem of scratching and damage of the surface of the polyurethane plate during the fixing process can be effectively avoided. As the connecting plate 10 continues to squeeze the fixing block 12 and deform under force, the two ends of the fixing block 12 move toward the ends away from each other. As for the outer wall surfaces on both sides of the bending part of the fixing block 12, they contact the limiting rings 16 on the same side. Under the influence of the two limiting rings 16, the fixing block 12 stops deforming, and then completes the fixation of the polyurethane plate. In the process of deformation of the fixing block 12, the impact force of the connecting plate 10 pressing down can be buffered, thereby further protecting the polyurethane plate from being damaged by force, ensuring that the plate will not be damaged after cutting is completed, affecting subsequent use, and reducing production costs.

[0030] A first T-shaped slide rail 3 is provided on each of the two auxiliary blocks 2, and two first T-shaped sliders 6 are movably connected inside the two first T-shaped slide rails 3. The top of the first T-shaped slider 6 is fixedly connected to the bottom of the corresponding U-shaped connecting rod 8 on the same side. A bidirectional screw 4 is movably connected inside one of the first T-shaped slide rails 3 through a bearing, and a first servo motor 5 is fixedly installed on one side of the auxiliary block 2 with the bidirectional screw 4 installed inside, and the output end of the first servo motor 5 passes through the interior of the auxiliary block 2 and is connected to one end of the bidirectional screw 4. A first threaded hole 7 is provided on the two first T-shaped sliders 6 inside the first T-shaped slide rail 3 with the bidirectional screw 4 installed inside, and the two first T-shaped sliders 6 inside the first T-shaped slide rail 3 with the bidirectional screw 4 installed inside are respectively threadedly connected to the two threaded surfaces on the bidirectional screw 4 through the first threaded holes 7.

[0031] When in use, the first servo motor 5 can drive the bidirectional screw 4 to rotate, and by rotating the bidirectional screw 4 in different directions, the two first T-shaped sliders 6 on the bidirectional screw 4 can move toward or away from each other, so that when in use, the two U-shaped connecting rods 8 can be controlled according to the size of the polyurethane plate to drive the two baffles 9 to approach each other to complete the clamping and fixing of the polyurethane plate. After the cutting is completed, the two U-shaped connecting rods 8 can be controlled to drive the two baffles 9 to move toward the side away from each other to release the polyurethane plate.

[0032] Two second T-shaped slide grooves 17 are symmetrically provided on both sides of the upper wall of the workbench 1. Second T-shaped sliders 19 are movably connected inside the two second T-shaped slide grooves 17. The top of the second T-shaped slider 19 is fixedly connected to the bottom of the same side of the adjusting rod 18.

[0033] A threaded rod 20 is movably connected to the interior of one of the second T-shaped slide grooves 17 through a bearing, and a second threaded hole 21 is opened on the second T-shaped slider 19 inside the second T-shaped slide groove 17 with the threaded rod 20 installed inside. The second T-shaped slider 19 inside the second T-shaped slide groove 17 with the threaded rod 20 installed inside is threadedly connected to the threaded rod 20 through the second threaded hole 21, and a second servo motor 22 is fixedly installed at a position on the outer wall of the workbench 1 corresponding to the second T-shaped slide groove 17 with the threaded rod 20 installed inside. The output end of the second servo motor 22 passes through the interior of the workbench 1 and is fixedly connected to the end corresponding to the threaded rod 20.

[0034] Similarly, when in use, the second servo motor 22 can drive the threaded rod 20 to rotate, thereby cooperating with the second T-shaped slider 19 to control the position adjustment of the adjusting rod 18 on the workbench 1, and the operation is simple.

[0035] Working principle:

[0036] When in use, the polyurethane plate to be cut is placed on the workbench 1, and then the two U-shaped connecting rods 8 are moved to drive the two baffles 9 to fix the two ends of the polyurethane plate, and then the polyurethane plate is fixed by the fixing mechanism on the two U-shaped connecting rods 8. Finally, the laser cutting machine 23 on the adjustment rod 18 is used to cut the polyurethane plate, and the electric telescopic rod 11 is used to control the connecting plate 10 to move up and down inside the U-shaped connecting rod 8, and the polyurethane plate is fixed by the fixing block 12 on the connecting plate 10. The two baffles 9 can be used to complete the left and right and up and down fixation of the polyurethane plate, thereby ensuring stability when cutting the polyurethane plate.

[0037] When the connecting plate 10 drives the fixing block 12 downward to fix the polyurethane plate, first, the arc-shaped gaskets 13 installed at both ends of the fixing block 12 will contact the polyurethane plate, and the arc-shaped gaskets 13 are arc-shaped elastic blocks with smooth surfaces, so the problem of scratching and damage of the surface of the polyurethane plate during the fixing process can be effectively avoided. As the connecting plate 10 continues to squeeze the fixing block 12 and deform under force, the two ends of the fixing block 12 move toward the ends away from each other. As for the outer wall surfaces on both sides of the bending part of the fixing block 12, they contact the limiting rings 16 on the same side. Under the influence of the two limiting rings 16, the fixing block 12 stops deforming, and then completes the fixation of the polyurethane plate. In the process of deformation of the fixing block 12, the impact force of the connecting plate 10 pressing down can be buffered, thereby further protecting the polyurethane plate from being damaged by force, ensuring that the plate will not be damaged after cutting is completed, affecting subsequent use, and reducing production costs.

[0038] When in use, the first servo motor 5 can drive the bidirectional screw 4 to rotate, and by rotating the bidirectional screw 4 in different directions, the two first T-shaped sliders 6 on the bidirectional screw 4 can move toward or away from each other, so that when in use, the two U-shaped connecting rods 8 can be controlled according to the size of the polyurethane plate to drive the two baffles 9 to approach each other to complete the clamping and fixing of the polyurethane plate. After the cutting is completed, the two U-shaped connecting rods 8 can be controlled to drive the two baffles 9 to move toward the side away from each other to release the polyurethane plate.
