Description

Technical Field

[0001] This utility model relates to the field of robotic arm parts processing technology, and in particular to a trimming and clamping device for robotic arm parts processing. Background Technology

[0002] Robotic arm parts are mostly produced by casting. After demolding, there are burrs at the interface of the mold cavity. Workers need to use grinding equipment to trim and polish the burrs on the demolded robotic arm parts to maintain the smoothness of the finished surface.

[0003] Currently, when trimming burrs on demolded robotic arm components, a fixture is often used to hold the robotic arm in place. Workers then use handheld grinding equipment to smooth the burrs. However, with a fixed fixture, the worker can only smooth burrs on one side of the component. To smooth burrs on the other side, the component must be removed from the fixture, and the process repeated on the other side. This process is cumbersome and labor-intensive. Furthermore, the component can loosen during processing due to pressure applied by the worker. To address these issues, a solution is proposed below. Utility Model Content

[0004] The purpose of this invention is to provide a trimming and clamping device for machining robotic arm parts, which has the advantages of easy adjustment of operating height and position and good fixing effect.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A trimming and clamping device for machining robotic arm parts includes a base, an electric telescopic rod mounted on the upper end of the base, a lifting plate fixed to the output shaft of the electric telescopic rod, a rotating shaft rotatably connected to the upper end of the lifting plate, an operating table fixed to the top of the rotating shaft, two drive boxes fixed to the bottom of the operating table, threaded rods respectively provided on one side of the two drive boxes, a rotating mechanism provided inside the drive boxes and connected to the threaded rods, threaded seats passing through the two threaded rods respectively, two sliding grooves opened at the upper end of the operating table, the upper sides of the two threaded seats slidably located in the two sliding grooves respectively, two clamping blocks provided at the upper end of the operating table, the two clamping blocks respectively fixed to the upper ends of the two threaded seats, a rotating wheel fixed to the rotating shaft, a plurality of limiting holes opened at equal angles on the outer side of the rotating wheel, a limiting mechanism provided on the lifting plate and the limiting mechanism cooperating with the limiting holes.

[0007] Preferably, the rotating mechanism includes a worm gear and a worm shaft disposed in the drive box, and the worm gear and the worm shaft mesh with each other. One end of the threaded rod passes through the drive box and is fixedly connected to the worm gear. One end of the threaded rod is rotatably connected to the inner wall of the drive box. A throttle handle is provided below the drive box. One end of the worm shaft passes through the drive box and is fixedly connected to the throttle handle. The other end of the worm shaft is rotatably connected to the inner wall of the drive box.

[0008] Preferably, the limiting mechanism includes a limiting post, a protrusion is fixedly provided at the upper end of the lifting plate, and the limiting post passes through the protrusion. The top end of the limiting post passes through the limiting hole, and a return spring passes through the limiting post. The two ends of the return spring are connected between one side of the protrusion and the tail end of the limiting post.

[0009] Preferably, the upper end of the base is fixedly provided with a plurality of guide cylinders, each of which is provided with a slidable guide post, and the top ends of the plurality of guide posts are respectively fixedly connected to the lower end of the lifting plate.

[0010] Preferably, anti-slip pads are fixed on one side of each of the two clamping blocks, and the anti-slip pads are elastic.

[0011] Preferably, the base has a storage cavity inside, and the front end of the base has a double-opening storage door.

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

[0013] 1. The electric telescopic rod can move the lifting plate up and down, thereby moving the rotating shaft and the operating table up and down simultaneously. The height of the operating table can be adjusted to accommodate different workers, allowing them to easily adjust it to a suitable height for processing robotic arm components. Rotating the operating table drives the rotating shaft, which in turn drives the rotating wheel, thus adjusting the processing position of the robotic arm components. A limiting mechanism can then restrict the rotation of the rotating wheel, fixing the position of the operating table. This eliminates the need to remove the robotic arm components from the fixture and then move them to the other side for finishing and grinding, effectively reducing the labor intensity of workers and further improving processing efficiency.

[0014] 2. The rotating mechanism can drive the threaded rod to rotate, thereby causing the threaded seat to move left and right along the threaded rod. At the same time, the threaded seat can slide left and right along the slide groove. The movement of the two threaded seats can drive the movement of the two clamping blocks respectively. When the robotic arm accessory is placed on the upper part of the operating table, the two clamping blocks can abut against the surface of the robotic arm accessory respectively, thereby clamping and fixing the robotic arm accessory, so as to facilitate the worker to perform grinding and processing operations.

[0018] The following description is merely a preferred embodiment of this utility model, and the scope of protection is not limited to this embodiment. All technical solutions falling within the scope of this utility model's concept should be protected. Identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom" and "top," "inner" and "outer" refer to directions toward or away from the geometric center of a specific component.

[0019] like Figs. 1-2 As shown, a trimming and clamping device for processing robotic arm parts includes a base 1. An electric telescopic rod 2 is mounted on the upper end of the base 1. A lifting plate 3 is fixedly mounted on the output shaft of the electric telescopic rod 2. A rotating shaft 4 is rotatably connected to the upper end of the lifting plate 3. An operating table 5 is fixedly mounted on the top of the rotating shaft 4. The electric telescopic rod 2 can drive the lifting plate 3 to move up and down, thereby driving the rotating shaft 4 and the operating table 5 to move up and down simultaneously. Therefore, the height of the operating table 5 can be adjusted to meet the needs of different operators, making it convenient for operators to adjust the operating table 5 to a suitable height for processing robotic arm parts. Several guide cylinders 21 are fixedly mounted on the upper end of the base 1. Each guide cylinder 21 is respectively equipped with a slidable guide post 22. The top ends of the guide posts 22 are respectively fixedly connected to the lower end of the lifting plate 3. When the operating table 5 moves up and down, it can drive the guide posts 22 to slide up and down along the guide cylinders 21, thus making the movement trajectory of the lifting plate 3 more straight and stable, further improving the stability of the device.

[0020] Two drive boxes 6 are fixedly installed at the bottom of the operating table 5. Each drive box 6 has a threaded rod 7 on one side. A rotating mechanism 8 is installed inside the drive box 6 and connected to the threaded rod 7. Threaded seats 9 are threaded through each of the two threaded rods 7. Two sliding grooves 10 are provided at the upper end of the operating table 5. The upper sides of the two threaded seats 9 are slidably located within the two sliding grooves 10. The rotating mechanism 8 drives the threaded rods 7 to rotate, thereby causing the threaded seats 9 to move left and right along the threaded rods 7, and simultaneously allowing the threaded seats 9 to slide left and right along the sliding grooves 10. Two clamping blocks 11 are provided at the upper end of the operating table 5, respectively fixed to the upper ends of the two threaded seats 9. Moving the two threaded seats 9 drives the two clamping blocks 11 to move. When the robotic arm component is placed on the upper end of the operating table 5, the two clamping blocks 11 abut against the surface of the robotic arm component, thereby clamping and fixing the component for easy grinding and processing operations.

[0021] The rotating mechanism 8 includes a worm gear 15 and a worm 16 disposed in the drive housing 6, and the worm gear 15 and the worm 16 mesh with each other. One end of the threaded rod 7 passes through the drive housing 6 and is fixedly connected to the worm gear 15. The other end of the threaded rod 7 is rotatably connected to the inner wall of the drive housing 6. A throttle 17 is provided below the drive housing 6. One end of the worm 16 passes through the drive housing 6 and is fixedly connected to the throttle 17. The other end of the worm 16 is rotatably connected to the inner wall of the drive housing 6. By rotating the throttle 17, the worm 16 can be rotated, thereby driving the worm gear 15 to rotate, and finally driving the threaded rod 7 to rotate. Since the worm gear 15 and the worm 16 have self-locking properties, the threaded rod 7 can be prevented from rotating back. Therefore, the stability of the clamping block 11 can be guaranteed, and the mechanical arm accessory clamped between the two clamping blocks 11 can be prevented from falling off due to the loosening of the clamping block 11. Therefore, the stability of the mechanical arm accessory clamping can be effectively improved.

[0022] A rotating wheel 12 is fixed on the rotating shaft 4. Several limiting holes 13 are opened at equal angles on the outer side of the rotating wheel 12. A limiting mechanism 14 is provided on the lifting plate 3, and the limiting mechanism 14 cooperates with the limiting holes 13. By rotating the operating table 5, the rotating shaft 4 can be driven to rotate, thereby driving the rotating wheel 12 to rotate. Therefore, the processing position of the robotic arm parts can be adjusted. Afterwards, the rotation of the rotating wheel 12 can be restricted by the limiting mechanism 14, thereby fixing the position of the operating table 5. Thus, the processing position of the robotic arm parts can be fixed, which can reduce the steps of removing the robotic arm parts from the fixture and then turning to the other side for repair and grinding. This effectively reduces the labor intensity of the workers and further improves the processing efficiency.

[0023] The limiting mechanism 14 includes a limiting post 18. A protrusion 19 is fixedly provided on the upper end of the lifting plate 3, and the limiting post 18 passes through the protrusion 19. The top end of the limiting post 18 passes through the limiting hole 13. A return spring 20 passes through the limiting post 18, and the two ends of the return spring 20 are connected between one side of the protrusion 19 and the tail end of the limiting post 18. By pulling the limiting post 18, the top end of the limiting post 18 can be dislodged from the limiting hole 13. At this time, the return spring 20 is stretched and generates elastic force. When the limiting post 18 is dislodged from the limiting hole 13, the rotating wheel 12 can be rotated, thereby realizing the rotation of the operating table 5. Conversely, when the operating table 5 is rotated to the appropriate position, the return spring 20 can drive the limiting post 18 back to the initial position, so that the top end of the limiting post 18 can be pushed back into the corresponding limiting hole 13. In this way, the rotation of the rotating wheel 12 can be restricted, and the position of the operating table 5 can be fixed.

[0024] Anti-slip pads 23 are fixed to one side of each of the two clamping blocks 11. These pads prevent the clamped robotic arm components from sliding, and the anti-slip pads 23 are elastic, preventing excessive clamping force from the clamping blocks 11 that could cause deformation of the robotic arm components. A storage cavity is provided inside the base 1, and a double-opening storage door 24 is located at the front end of the base 1. By opening the storage door 24, the operator's tools can be stored, thus improving the practicality of the device.

[0025] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
