Description

Technical Field

[0001] This utility model relates to the field of cutting and grinding technology, and in particular to a cutting and grinding mechanism for an AGV-mounted robot. Background Technology

[0002] AGV (Automated Guided Vehicle) robots are wheeled mobile robots that can automatically drive according to preset paths and instructions without human intervention, completing tasks such as material handling and cargo transportation.

[0003] In traditional such mechanisms, the cutting and grinding devices are often fixed in a specific position and cannot be moved flexibly. For example, when processing large irregular workpieces, the cutting and grinding devices cannot be moved to the required position, so only the easily accessible parts of the workpiece can be processed. They are helpless when dealing with special parts such as recesses and corners, which greatly limits the comprehensiveness of processing and is not practical enough. Therefore, it is necessary to redesign an AGV-mounted robot cutting and grinding mechanism to address the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cutting and grinding mechanism for AGV (Automated Guided Vehicle) robots.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An AGV-mounted robot cutting and grinding mechanism includes a worktable. Two support legs are fixedly installed on the bottom wall of the worktable. A support plate is fixedly installed on the bottom wall of the worktable. A connecting frame is fixedly installed on the inner wall of the support plate via a lifting mechanism. A double-headed threaded rod is rotatably installed inside the connecting frame. A first motor connected to the double-headed threaded rod is fixedly installed on the outer wall of the connecting frame. Two moving blocks are threadedly installed on the outer wall of the double-headed threaded rod via a limiting mechanism. A pressure plate is fixedly installed on the upper surface of each of the two moving blocks via a connecting mechanism. A second motor is fixedly installed on the upper surface of the worktable via a fixing plate. A gear is fixedly installed on the outer wall of the output shaft of the second motor. A slide rod is fixedly installed on the inner wall of the fixing plate via a mounting frame. Two sliders are slidably installed on the outer wall of the slide rod. A toothed plate is fixedly installed on the outer wall of each of the two sliders via a connecting mechanism. The toothed plate and the gear mesh with each other. An electric push rod is fixedly installed on the bottom wall of each of the two sliders. A grinding device and a cutting device are respectively fixedly installed on the telescopic ends of the two electric push rods.

[0007] Preferably, the lifting mechanism includes a cylinder fixedly installed on the inner wall of the support plate, and the telescopic end of the cylinder is fixedly connected to the bottom wall of the connecting frame.

[0008] Preferably, the limiting mechanism includes a limiting rod fixedly installed inside the connecting frame, the limiting rod sliding through the two moving blocks.

[0009] Preferably, the connecting mechanism includes a connecting rod fixedly installed on the upper surface of the movable block, and the end of the connecting rod is fixedly connected to the upper surface of the lower pressure plate.

[0010] Preferably, the connecting mechanism includes a connecting rod fixedly installed on the outer wall of the slider, and the end of the connecting rod is fixedly connected to the outer wall of the toothed plate.

[0011] Preferably, both of the lower pressure plates are fixedly equipped with protective pads, and both protective pads are made of rubber.

[0012] The beneficial effects of this utility model are:

[0013] 1. By setting up components such as slide rods, sliders, gears and toothed plates, the rotation of the gears is converted into linear motion of the toothed plates through the meshing transmission of the toothed plates and gears. With the help of the connecting rod, the slider that can slide on the slide rod moves, thereby realizing the flexible horizontal position adjustment of the electric push rod installed on the bottom wall of the slider and the grinding and cutting devices connected to its telescopic end, which greatly improves the flexibility of cutting and grinding different parts of the workpiece.

[0014] 2. By setting up components such as a double-ended threaded rod, a limiting rod, and a lower pressure plate, the double-ended threaded rod can drive two moving blocks to move when it rotates, through cooperation with the limiting rod. The movement of the moving blocks will be transmitted to the lower pressure plate through the connecting rod, so that the two lower pressure plates gradually approach each other and press the workpiece firmly on the worktable, avoiding the workpiece from shifting its position during cutting and grinding, which would affect the cutting and grinding effect.

[0021] 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.

[0022] Reference Figure 1-5 An AGV-mounted robot cutting and grinding mechanism includes a worktable 1, two support legs 2 fixedly installed on the bottom wall of the worktable 1, a support plate 3 fixedly installed on the bottom wall of the worktable 1, a connecting frame 5 fixedly installed on the inner wall of the support plate 3 via a lifting mechanism, the lifting mechanism including a cylinder 4 fixedly installed on the inner wall of the support plate 3, the telescopic end of the cylinder 4 being fixedly connected to the bottom wall of the connecting frame 5, a double-headed threaded rod 6 rotatably installed inside the connecting frame 5, a first motor 7 fixedly installed on the outer wall of the connecting frame 5 and connected to the double-headed threaded rod 6, and two moving blocks 9 threadedly installed on the outer wall of the double-headed threaded rod 6 via a limiting mechanism, the limiting mechanism including a limiting rod fixedly installed inside the connecting frame 5. 8. The limiting rod 8 slides through the two moving blocks 9, so that the two moving blocks 9 can only move axially along the outer wall of the double-threaded rod 6. The upper end face of the two moving blocks 9 is fixedly installed with a lower pressure plate 11 through a connecting mechanism. The connecting mechanism includes a connecting rod 10 fixedly installed on the upper end face of the moving block 9. The end of the connecting rod 10 is fixedly connected to the upper end face of the lower pressure plate 11. Both lower pressure plates 11 are fixedly installed with protective pads. Both protective pads are made of rubber. Rubber material has good elasticity and softness, which allows it to form a tighter contact between the surface and the object, thereby increasing friction and improving the coefficient of friction.

[0023] A second motor 13 is fixedly installed on the upper surface of the workbench 1 via a fixing plate 12. A gear 14 is fixedly installed on the outer wall of the output shaft of the second motor 13. A slide rod 16 is fixedly installed on the inner wall of the fixing plate 12 via a mounting frame 15. Two sliders 17 are slidably installed on the outer wall of the slide rod 16. A toothed plate 19 is fixedly installed on the outer wall of both sliders 17 via a connecting mechanism. The connecting mechanism includes a connecting rod 18 fixedly installed on the outer wall of the slider 17. The end of the connecting rod 18 is fixedly connected to the outer wall of the toothed plate 19. The toothed plate 19 and the gear 14 mesh with each other. An electric push rod 20 is fixedly installed on the bottom wall of both sliders 17. A grinding device 21 and a cutting device 22 are fixedly installed on the telescopic ends of the two electric push rods 20, respectively.

[0024] When this utility model is in use, when the workpiece needs to be processed, the workpiece is first placed on the worktable 1. At this time, under the extension and retraction of the cylinder 4, the connecting frame 5 can be pushed to move upward. As the connecting frame 5 rises, the associated components will also rise until the lower pressure plate 11 approaches the workpiece. Then, the first motor 7 drives the double-headed threaded rod 6 to rotate. When the double-headed threaded rod 6 rotates, it can drive the two moving blocks 9 to move through the cooperation with the limit rod 8. The movement of the moving blocks 9 will be transmitted to the lower pressure plate 11 through the connecting rod 10, so that the two lower pressure plates 11 gradually approach each other and press the workpiece on the worktable 1, so as to avoid the workpiece from shifting its position during cutting and grinding, which would affect the cutting and grinding effect. In addition, the rubber protective pad can play a buffering role to prevent damage to the surface of the workpiece during the pressing process.

[0025] After the workpiece is pressed down and fixed, the output shaft of the second motor 13 starts to rotate, thereby driving the gear 14 fixed on the outer wall of the output shaft to rotate. Since the gear plate 19 and the gear 14 mesh with each other, the rotation of the gear 14 will be converted into the linear motion of the gear plate 19. Since the gear plate 19 is fixedly connected to the slider 17 through the connecting rod 18, and the slider 17 can slide on the slide rod 16, the linear motion of the gear plate 19 will drive the slider 17 to move on the slide rod 16. In this way, the electric push rod 20 installed on the bottom wall of the slider 17 and the grinding device 21 and cutting device 22 at the telescopic end of the electric push rod 20 can be adjusted in the horizontal direction, thereby moving above the workpiece to be processed.

[0026] Once the grinding device 21 or the cutting device 22 reaches the appropriate position through horizontal movement, the corresponding electric push rod 20 is activated. The telescopic end of the electric push rod 20 extends or retracts, pushing the grinding device 21 or the cutting device 22 to move vertically. When the telescopic end extends, the grinding device 21 or the cutting device 22 approaches the workpiece and performs cutting or grinding operations on it. After completing the processing of one part, the horizontal position of the grinding device 21 and the cutting device 22 can be adjusted again by the second motor 13, and their vertical position can be adjusted by the electric push rod 20, thereby processing other parts of the workpiece and realizing flexible cutting and grinding of different parts of the workpiece.

[0027] 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.
