Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figures 1-4 An automatic flipping double-sided sanding machine includes a base 1, with several support legs 23 installed on the bottom edge of the base 1, and a control cabinet 19 between the support legs 23. The top of the control cabinet 19 is fixed to the bottom of the base 1, and a controller is installed inside the control cabinet 19. The controller is one of a control motherboard, a host, or a PLC logic controller.

[0027] like Figure 1 and Figure 3As shown, two guide rails 22 are symmetrically installed on the top of the base 1. A linear drive module 20 is connected to each guide rail 22, and the tops of the two linear drive modules 20 are connected by a strip-shaped moving plate 26. A second mounting plate 24 is symmetrically provided on the top of the strip-shaped moving plate 26. A grinding disc 6 is rotatably connected to the adjacent surfaces of the two second mounting plates 24. One end of each grinding disc 6 is connected to a first drive motor 7. The first drive motor 7 is fixed on the corresponding second mounting plate 24. The linear drive module 20 and the first drive motor 7 are connected to the controller through wires. In actual use, the first drive motor 7 can drive the grinding disc 6 to rotate, and the linear drive module 20 can drive the two grinding discs 6 to move horizontally, so that the two sides of the workpiece can be ground synchronously.

[0028] like Figure 1 and Figure 3 As shown, a second fixed plate 29 is installed at both ends of the top of the strip-shaped moving plate 26. A second telescopic mechanism 21 is installed on one side of each second fixed plate 29. The other end of the second telescopic mechanism 21 is fixed to the side of the corresponding second mounting plate 24. The second telescopic mechanism 21 is one of an electric push rod, a cylinder, or a hydraulic rod. In actual use, the second fixed plate 29 can be moved along the strip-shaped moving plate 26 by the second telescopic mechanism 21, so that the distance between the two grinding discs 6 can be adjusted as needed, so that the surface of the grinding disc 6 contacts the workpiece and processes the workpiece.

[0029] like Figure 3 As shown, the top of the strip-shaped moving plate 26 is provided with a mounting groove 16, and several infrared sensors 15 are installed at the bottom of the mounting groove 16. The top of the infrared sensors 15 is located inside the mounting groove 16. The infrared sensors 15 are connected to the controller through wires. In actual use, the outline of the workpiece can be detected by the infrared sensors 15, and the detection data is transmitted to the controller. The controller controls the extension of the second telescopic mechanism 21 to move the grinding disc 6 to a preset position, so that it can contact the surface of the workpiece and perform grinding processing on the surface of the workpiece.

[0030] It should be noted that L-shaped limiting plates 30 are installed on both sides of the top of the strip-shaped moving plate 26, and a wedge-shaped groove is formed between the two L-shaped limiting plates 30. The bottom of the second mounting plate 24 is located in the wedge-shaped groove, and the second mounting plate 24 is slidably connected to the L-shaped limiting plates 30. In actual use, the L-shaped limiting plates 30 can limit the second mounting plate 24, so that the second mounting plate 24 remains stable.

[0031] like Figure 1 and Figure 4As shown, a through groove 2 is provided on the top of the base 1. A bidirectional lead screw 25 is rotatably connected inside the through groove 2. One end of the bidirectional lead screw 25 is connected to a second drive motor 18. The second drive motor 18 is fixed on the base 1 by a first fixing plate 17. The second drive motor 18 is connected to the controller by a wire. In actual use, the second drive motor 18 can drive the bidirectional lead screw 25 to rotate.

[0032] It should be noted that the top of the through groove 2 is equipped with a telescopic dust cover, which can block the top opening of the through groove 2 to prevent debris from adhering to the bidirectional lead screw 25 during the grinding process.

[0033] like Figure 1 and Figure 4 As shown, both ends of the bidirectional lead screw 25 are fitted with connecting blocks 32, both ends of which extend to the outside of the through groove 2. Each connecting block 32 is topped with a first mounting plate 3. The adjacent surfaces of the two first mounting plates 3 are rotatably connected to a rotating shaft 27. The adjacent ends of the two rotating shafts 27 are fitted with clamping plates 5. In actual use, when the second drive motor 18 drives the bidirectional lead screw 25 to rotate, the two connecting blocks 32 will move relative to each other, which in turn will cause the two clamping plates 5 to move relative to each other. The operator can place the workpiece to be processed between the two clamping plates 5, and the clamping plates 5 can clamp and fix the workpiece.

[0034] It should be noted that the size of the clamping plate 5 is smaller than the size of the workpiece being processed, so that the grinding disc 6 will not collide with the clamping plate 5 during grinding.

[0035] like Figure 1 and Figure 2 As shown, one end of one of the rotating shafts 27 passes through the first mounting plate 3 and is connected to a gear 8. A strip connecting plate 11 is provided on one side of the gear 8, and a rack 9 is connected to one side of the strip connecting plate 11. The rack 9 meshes with the gear 8, and a first fixing block 12 is installed at the bottom of the strip connecting plate 11. The bottom of the first fixing block 12 is connected to the bottom of the first mounting plate 3 through a first telescopic mechanism 14. The first telescopic mechanism 14 is either an electric push rod or a hydraulic rod. The first telescopic mechanism 14 is connected to the controller through a wire. In actual use, the rack 9 can be moved by the first telescopic mechanism 14, which will drive the gear 8 to rotate. The gear 8 will drive the clamping plate 5 to rotate under the action of the rotating shaft 27, thus completing the automatic flipping of the workpiece.

[0036] like Figure 2 As shown, a strip guide plate 10 is installed on one side of the strip connecting plate 11. The strip guide plate 10 is slidably connected to the slide rail 13 fixed on the side of one of the first mounting plates 3. In actual use, the rack 9 can be limited by the cooperation of the strip guide plate 10 and the slide rail 13, so that the rack 9 can remain stable.

[0037] It should be noted that a laser rangefinder 34 is installed on the bottom edge of the first fixed block 12. The laser rangefinder 34 is connected to the controller via a wire. In actual use, the laser rangefinder 34 can detect the moving distance of the first fixed block 12 and transmit the detection data to the controller. The controller can control the extension distance of the first telescopic mechanism 14, thereby controlling the flipping angle of the workpiece and improving the performance.

[0038] Specifically, in use, the operator places the workpiece to be processed between two clamping plates 5, then controls the second drive motor 18 to rotate, causing the bidirectional lead screw 25 to rotate, thereby moving the two clamping plates 5 relative to each other and clamping and fixing the workpiece. Then, the infrared sensor 15 detects the contour of the workpiece and transmits the detection data to the controller. The controller controls the second telescopic mechanism 21 to extend, pushing the second mounting plate 24 to move, thus moving the grinding disc 6 to a preset position. Then, the first drive motor 7 is controlled to rotate, and the controller synchronously controls the linear drive module 20 to move along the guide rail 22, thereby moving the grinding disc 6 horizontally, so that the grinding disc 6 contacts the workpiece surface and grinds the workpiece. The grinding disc 6 is then applied to both sides of the workpiece. After grinding, the operator controls the extension of the first telescopic mechanism 14, which pushes the rack 9 to move, thereby driving the gear 8 to rotate. Under the action of the rotating shaft 27 and the clamping plate 5, the workpiece can be flipped. During the extension of the first telescopic mechanism 14, the laser range sensor 34 can detect the moving distance of the first fixed block 12 and transmit the data to the controller. The controller controls the extension stroke of the first telescopic mechanism 14, so that the workpiece is flipped at a preset angle. After that, the infrared sensor 15 detects the outline of the workpiece and transmits the data to the controller. The controller controls the extension of the second telescopic mechanism 21, which adjusts the grinding disc 6 to the preset position again. Then the controller controls the linear drive module 20 to move in the opposite direction. The grinding disc 6 grinds the surface of the flipped workpiece, thus completing the multi-face grinding of the workpiece.

[0039] Furthermore, such as Figure 4 As shown, a second fixing block 33 is installed on both sides of the bottom of the base 1. A guide rod 31 is connected between the two second fixing blocks 33. The bottom of the connecting block 32 is slidably sleeved on the side of the guide rod 31. With the cooperation of the guide rod 31 and the connecting block 32, the connecting block 32 can be limited, so that the connecting block 32 remains stable, thereby making the first mounting plate 3 and the clamping plate 5 stable.

[0040] Furthermore, such as Figure 2 Figure 2As shown, each shaft 27 has a connecting plate 4 installed on its side, and each clamping plate 5 has at least one reinforcing rod 28 installed on the side of the clamping plate 4. The other end of the reinforcing rod 28 is fixed to the side of the corresponding connecting plate 4. With the cooperation of the reinforcing rod 28 and the connecting plate 4, the clamping plate 5 can be supported, increasing the stability of the clamping plate 5.

[0041] Furthermore, a transparent dustproof plate is provided at the opening of the mounting slot 16. The transparent dustproof plate can block the debris generated during the grinding process, preventing the debris from falling into the mounting slot 16 and blocking the infrared sensor 15.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
