Description

Technical Field

[0001] This utility model relates to the field of lidar installation technology, specifically to an auxiliary calibration component for robot line lidar. Background Technology

[0002] In the field of modern industrial automation, the collaborative operation of robotic line LiDAR (such as LiDAR) and robotic arms is widely used in scenarios such as high-precision measurement, 3D reconstruction, and target recognition. To achieve precise collaborative work between the radar and the robotic arm, they need to be rigidly connected through calibration components, and the repeatability and stability of the installation position must be ensured.

[0003] However, traditionally, the radar is fixed to the flange of the robotic arm or the calibration component by bolts. When disassembling or adjusting the radar, each bolt needs to be tightened or loosened one by one, which is cumbersome and time-consuming. This seriously affects work efficiency, especially in application scenarios where the radar is frequently replaced or calibrated. In order to solve the above problems, the inventors have proposed a robot line lidar auxiliary calibration component. Utility Model Content

[0004] To address the problem of inconvenient maintenance of line lidar, the purpose of this utility model is to provide an auxiliary calibration component for robot line lidar.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: a robot line lidar auxiliary calibration component, comprising a robot mounting surface and a lidar body, wherein a mounting base is fixedly connected to the top of the robot mounting surface, a protrusion is fixedly connected to the top of the mounting base, and snap-fit ​​blocks are fixedly connected to both sides of the top of the protrusion; a connecting base is fixedly connected to the bottom of the lidar body, and a slot is provided in the middle of the bottom of the connecting base; two symmetrically distributed guide grooves are provided on the bottom of the connecting base near the slot; a snap-fit ​​slot is provided inside the connecting base near the slot, and the guide grooves communicate with the interior of the snap-fit ​​slot; the diameter of the slot is smaller than the diameter of the snap-fit ​​slot.

[0006] Preferably, the lidar body has an internal movable groove, a slider is slidably engaged inside the movable groove, an insert is fixedly connected to the bottom end of the slider, and a second slot is provided on the side of the mounting base near the slider, the insert is movably engaged in the second slot.

[0007] Preferably, a fixed frame is fixedly connected to the side of the lidar body near the slider, a pressing block is slidably engaged with the fixed frame, a telescopic rod is fixedly connected to the side of the pressing block near the slider, a trapezoidal groove is formed on one side of the slider, the end of the telescopic rod away from the pressing block is movably inserted into the interior of the trapezoidal groove and abuts against the inclined surface of the trapezoidal groove, a spring is provided between the top surface of the slider and the inner wall of the movable groove, a limit block is fixedly connected to the end of the telescopic rod away from the pressing block, and the end of the pressing block away from the telescopic rod protrudes to the outside of the fixed frame.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example: Figure 1-4 As shown, this utility model provides a robot line lidar auxiliary calibration component, including a robot mounting surface 1 and a lidar body 2. A mounting base 3 is fixedly connected to the top of the robot mounting surface 1, and a protrusion 5 is fixedly connected to the top of the mounting base 3. Both sides of the top of the protrusion 5 are fixedly connected to snap-fit ​​blocks 8. A connecting base 4 is fixedly connected to the bottom of the lidar body 2. A slot 6 is provided in the middle of the bottom of the connecting base 4. Two symmetrically distributed guide grooves 9 are provided on the bottom side of the connecting base 4 near the slot 6. A snap-fit ​​groove 7 is provided inside the connecting base 4 on the side near the slot 6. The guide grooves 9 and the snap-fit ​​groove 7 communicate with each other.

[0019] The lidar body 2 has an internal movable groove 11, and a slider 12 is slidably engaged inside the movable groove 11. A plug 13 is fixedly connected to the bottom end of the slider 12. The mounting base 3 has a second slot 14 on the side near the slider 12, and the plug 13 is movably engaged in the second slot 14.

[0020] By adopting the above technical solution, the relative rotation between the lidar body 2 and the mounting base 3 is limited by inserting the insert block 13 into the slot 2 14.

[0021] A fixed frame 15 is fixedly connected to the side of the lidar body 2 near the slider 12. A pressing block 16 is slidably engaged with the fixed frame 15. A telescopic rod 17 is fixedly connected to the side of the pressing block 16 near the slider 12. A trapezoidal groove 19 is opened on one side of the slider 12. The end of the telescopic rod 17 away from the pressing block 16 is movably inserted into the interior of the trapezoidal groove 19 and abuts against the inclined surface of the trapezoidal groove 19.

[0022] By adopting the above technical solution, pressing the pressing block 16 pushes the telescopic rod 17 to one side of the slider 12, and the inclined surface of the slider 12 guides the movement of the telescopic rod 17. At the same time, the slider 12 is driven to move to one side of the spring 10 and compresses the spring 10, so that the insert block 13 is pulled out from the inside of the slot 14, thereby releasing the restriction on the relative rotation between the laser radar body 2 and the mounting base 3 and completing the unlocking operation.

[0023] A spring 10 is provided between the top surface of the slider 12 and the inner wall of the movable groove 11.

[0024] By adopting the above technical solution, the slider 12 can be reset by setting the spring 10. At the same time, the elastic force of the spring 10 makes the insertion of the plug 13 more secure.

[0025] The end of the telescopic rod 17 away from the pressing block 16 is fixedly connected to the limit block 18.

[0026] By adopting the above technical solution and setting the limiting block 18, the lateral movement of the telescopic rod 17 can be limited, preventing the telescopic rod 17 from being pulled out of the trapezoidal groove 19.

[0027] The end of the pressing block 16 away from the telescopic rod 17 protrudes to the outside of the fixing frame 15.

[0028] By adopting the above technical solution, by setting the end of the pressing block 16 away from the telescopic rod 17 to protrude to the outside of the fixed frame 15, it is easier to press the pressing block 16 and complete the unlocking operation.

[0029] The diameter of slot 6 is smaller than the diameter of slot 7.

[0030] By adopting the above technical solution, and by setting the diameter of slot 6 to be smaller than the diameter of slot 7, the snap-fit ​​block 8 can snap-fit ​​with slot 7.

[0031] Working principle: When connecting the robot's linear laser radar to the robot, the guide groove 9 is aligned with the position of the locking block 8, and then the locking block 8 is movably inserted into the guide groove 9, so that the locking block 8 is fully inserted into the slot 7. At this time, the opposite sides of the mounting base 3 and the connecting base 4 are in contact, and the insertion block 13 is in a compressed state. Then, by rotating the connecting base 4 horizontally, the locking block 8 and the slot 7 are locked together, thereby limiting the separation operation of the laser radar body 2 and the mounting base 3. When the connecting base 4 rotates to the position where the insertion block 13 aligns with the slot 14, the elastic force of the spring 10 causes the insertion block 13 to be movably inserted into the slot 14, thereby limiting the relative rotation of the mounting base 3 and the connecting base 4, and thus completing the installation operation of the laser radar body 2.

[0032] When it is necessary to disassemble the lidar body 2, press the pressing block 16 to push the telescopic rod 17 to one side of the slider 12, and use the inclined surface of the slider 12 to guide the movement of the telescopic rod 17. At the same time, the slider 12 is driven to move to one side of the spring 10 and compress the spring 10, so that the insert block 13 is pulled out from the inside of the slot 14, thereby releasing the restriction on the relative rotation between the lidar body 2 and the mounting base 3. Then, rotate the connecting base 4 horizontally so that the position of the locking block 8 corresponds with the guide groove 9, thereby facilitating the disassembly of the lidar body 2.

[0033] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
