Description

Technical Field

[0001] This utility model relates to the field of robotic arm technology, specifically a rotatable robotic arm. Background Technology

[0002] A robotic arm is an automated operating device that can mimic certain movements and functions of a human hand and arm to grasp, move objects, or operate tools according to a fixed program. A robotic arm mainly consists of three parts: an actuator, a drive mechanism, and a control system. Robotic arms are widely used in various fields and can replace heavy human labor, realizing the mechanization and automation of production.

[0003] Regarding the above and existing related technologies: In industrial production, robotic arms are often used for production. Most robotic arms have relatively fixed workstations. In actual use, if a robotic arm needs to be replaced, it needs to be disassembled and reinstalled. This can easily lead to cumbersome disassembly and replacement operations when multiple robotic arms need to be replaced at the same time. Therefore, a rotatable robotic arm is proposed to address the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The rotatable manipulator of this utility model includes a base, a fixed seat, and a fixing device. The fixed seat is located directly above the base, and a manipulator is fixedly connected to the surface of the fixed seat. The fixing device is disposed on the surface of the base and the fixed seat. The fixing device includes two support columns, the bottom ends of the two support columns are fixedly connected to the upper surface of the base, and clamping rings are rotatably connected to the surface of the support columns. Two limiting rings are fixedly connected to the surface of the fixed seat, and two locking blocks are fixedly connected to the bottom ends of the limiting rings. The locking blocks are inserted into the inner wall of the base, and the clamping rings are located on the upper surface of the limiting rings. Pushing the clamping rings causes them to rotate on the surface of the support columns. The clamping rings rotate to the surface of the limiting rings. By setting the support columns, limiting rings, locking blocks, and clamping rings, the position of the fixed seat can be fixed.

[0006] Preferably, a placement block is fixedly connected to the upper surface of the base, and a limiting block is slidably connected to the inner wall of the placement block. The limiting block is inserted into the inner wall of the two clamping rings. By setting the placement block and the limiting block, the angle of the clamping rings can be limited.

[0007] Preferably, a connecting block is fixedly connected to the surface of the limiting block. The connecting block is located on one side of the placement block and is blocked by the placement block. By setting the connecting block, the position of the limiting block can be restricted.

[0008] Preferably, the sidewall of the connecting block and the sidewall of the placement block are fixedly connected by two springs. When the connecting block is released, the springs will drive the connecting block to move. By setting the springs, the position of the connecting block can be limited.

[0009] Preferably, a pull ring is fixedly connected to the side wall of the limiting block. When it is necessary to move the limiting block, the pull ring is pulled to move the limiting block. The pull ring facilitates the movement of the limiting block.

[0010] Preferably, the surface of the base is provided with multiple limiting devices, each including a threaded rod. The surface of the threaded rod is threaded to the inner wall of the base, and a pad is rotatably connected to the bottom end of the threaded rod. Multiple anti-slip strips are fixedly connected to the bottom end of the pad. The threaded rod drives the pad and anti-slip strips to move, and the anti-slip strips are pressed against the ground. By setting the threaded rod, pad, and anti-slip strips, the position of the base can be limited.

[0011] Preferably, two sliding columns are fixedly connected to the upper surface of the pad, the surface of the sliding column is slidably connected to the inner wall of the base, and a fixing block is fixedly connected to the upper surface of the two sliding columns. The fixing block is sleeved on the surface of the threaded rod. When the sliding column slides, it will drive the fixing block to move. By setting the sliding column and the fixing block, the threaded rod can be supported.

[0012] The advantages of this utility model are:

[0013] 1. When a fixed base is needed, this utility model places the fixed base on the base. When the fixed base moves, it will drive the limiting ring and the locking block to move. The locking block is inserted into the inner wall of the base. Then, pulling the pull ring will drive the limiting block to move. The limiting block slides on the inner wall of the placement block. When the limiting block slides, it will also drive the connecting block to slide. The connecting block will drive the spring to contract, and then push the clamping ring to rotate on the surface of the support column. The clamping ring rotates to the surface of the limiting ring. Then, releasing the pull ring will drive the spring to drive the connecting block and the limiting block to slide. The limiting block is inserted into the inner wall of the clamping ring. By setting the entire device, the position of the fixed base can be fixed, and the robotic arm can be easily replaced, reducing operation time.

[0014] 2. When the base needs to be used, the threaded rod is rotated to rotate on the inner wall of the base. The threaded rod drives the pad and anti-slip strip to move. The anti-slip strip is pressed against the ground. When the pad moves, it will drive the sliding column to move. The sliding column slides on the inner wall of the base. When the sliding column slides, it will also drive the fixed block to move. By setting the entire device, the situation of the base moving randomly can be reduced. Attached Figure Description

[0026] Two springs 48 are fixedly connected to the side wall of the connecting block 47 and the side wall of the placement block 45. During operation, the connecting block 47 drives the springs 48 to contract. When using the connecting block 47, the connecting block 47 is released, and the springs 48 drive the connecting block 47 to move.
