Description

Technical Field

[0001] This utility model relates to a polishing head assembly, specifically a polishing head assembly mechanism for a robotic arm, belonging to the technical field of polishing equipment. Background Technology

[0002] In the field of industrial automation, robotic arms are widely used in processes such as workpiece surface polishing, deburring, and dust removal. As the core actuator at the end of the robotic arm, the polishing head needs to be frequently replaced to adapt to different working conditions or to replace worn components.

[0003] Most existing polishing heads are integrally molded and the connecting part is installed on the power equipment at the end of the robotic arm by bolts or welding. When the polishing head is damaged after long-term use, it is necessary to use other tools (wrench, pliers, etc.) to disassemble the entire polishing head and connecting part from the output end of the power equipment. The operation is relatively troublesome and not convenient for operators to quickly disassemble and assemble.

[0004] Therefore, a polishing head assembly mechanism for a robotic arm is proposed here. Utility Model Content

A connecting plate is fixed to the robotic arm output end, and a fixing component is disposed inside the connecting plate. A fixing plate is fixed to the upper surface of the polishing block. The connecting plate is fixed to the upper surface of the polishing block by the fixing component and the fixing plate. A sealing cover plate is also disposed above the connecting plate, and the sealing cover plate is fixed to the side of the fixing plate.

[0007] The fixing component includes a spur gear, the surface of the connecting plate has a placement groove, the spur gear is disposed inside the placement groove, the lower surface of the spur gear is fixedly connected to a first bevel gear, the connecting plate has a transmission chamber, and the first bevel gear is disposed inside the transmission chamber.

[0008] Furthermore, a threaded rod is rotatably connected to the inner wall of the transmission chamber, and a second bevel gear is fixed to the surface of the threaded rod. The first bevel gear and the second bevel gear mesh with each other. A threaded tube is threadedly connected to the surface of the threaded rod, and a second snap-fit ​​plate is fixed to the other end of the threaded tube. A first snap-fit ​​plate is fixed to the side of the fixing plate. The first snap-fit ​​plate and the second snap-fit ​​plate cooperate with each other. A groove is also provided on the side of the connecting plate, and the second snap-fit ​​plate is disposed inside the groove.

[0009] Furthermore, the fixing assembly also includes a rotating plate disposed on the outer periphery of the output end of the robotic arm. A toothed ring is embedded on the side of the rotating plate, and the spur gear and the toothed ring are combined. A lever is also fixed on the side of the rotating plate, and the rotating plate is rotated and disposed on the outer periphery of the output end of the robotic arm by the lever.

[0010] Furthermore, a slider is fixed to the side of the threaded tube, and a groove corresponding to the slider is opened on the inner wall of the transmission chamber. The slider moves inside the groove, and the threaded tube moves inside the transmission chamber through the slider and the groove. There are two sliders and two grooves, which are symmetrically arranged on both sides of the threaded tube.

[0011] Furthermore, the sealing cover plate has a telescopic groove on its surface, a support rod is fixed to the inner wall of the telescopic groove, a limit rod is sleeved on the surface of the support rod, a limit groove corresponding to the limit rod is opened on the inner side wall of the fixed plate, one end of the limit rod is engaged in the limit groove, a pull rod is rotatably connected to the upper surface of the limit rod, and a movable groove is also opened on the surface of the sealing cover plate, the telescopic groove and the movable groove are connected, and the pull rod passes through the movable groove.

[0012] Furthermore, a stop block is fixed on the upper surface of the sealing cover plate. The stop blocks are symmetrically arranged on both sides of the pull rod. A spring is also sleeved on the outer periphery of the support rod. The two ends of the spring are respectively fixed to the inner wall of the telescopic groove and the side of the limiting rod.

[0013] This utility model provides a polishing head assembly mechanism for a robotic arm, which has the following beneficial effects:

[0014] 1. The polishing head assembly mechanism of this robotic arm drives the rotating plate to rotate by rotating the lever, thereby driving the toothed plate embedded on the side of the rotating plate to rotate synchronously. The toothed ring drives the spur gear meshing with it to rotate, and the spur gear drives the coaxial first bevel gear to rotate. The first bevel gear meshes with the second bevel gear to rotate the threaded rod, thereby pushing the threaded tube to move horizontally, so that the first and second snap-fit ​​plates can snap / separate, thus completing the installation / removal of the polishing block, shortening the disassembly and installation time, and eliminating the need to use tools such as wrenches and pliers, reducing the difficulty of disassembly.

[0015] 2. The polishing head assembly mechanism of this robotic arm moves a limit rod by pulling a pull rod, causing the limit rod to move into the telescopic groove. This allows the sealing cover plate to be placed on the upper surface of the mounting plate. Then, by releasing the pull rod, the reaction force of the spring pushes out one end of the limit rod and locks it into the limit groove. This prevents dust, debris, and other impurities generated during the polishing process from entering the connection area, protecting the internal mechanical parts and connection points. It not only reduces the impact of contaminants on the equipment but also prevents damage to the connection plate caused by external impacts or accidental collisions. Attached Figure Description
