Rapid replacing structure for tail end of mechanical arm and electric mechanical arm

Abstract

The invention discloses a rapid replacing structure for the tail end of a mechanical arm and an electric mechanical arm. The rapid replacing device comprises an installing base, a drive device, a moving lock device and a tail end installing module. The drive device is arranged on the installing base and connected with a first bevel gear capable of rotating. The moving lock device comprises a screwrod shaft, a second bevel gear and a sliding block. The screw rod shaft is arranged on the installing base. The second bevel gear is fixedly connected to the first end of the screw rod shaft and engaged with the first bevel gear. The sliding block is connected to the second end of the screw rod shaft in a threaded manner and can carry out relative thread rotating, and thus the sliding block can move horizontally along the axis of the screw rod shaft. The tail end installing module is buckled to the installing base in a covering manner, and the inner wall of the tail end installing module is provided with a ring-shaped groove corresponding to the sliding block. By the utilization of the rapid replacing structure, the replacing process of the tail end installing module can be completed rapidly, meanwhile, the gear transmission manner can ensure the stability of clamping between the sliding block and the ring-shaped groove, and thus convenience of replacing the tail end installing moduleis improved.

Description

technical field [0001] The invention relates to the field of robots, in particular to a quick replacement structure for the end of a manipulator and an electric manipulator. Background technique [0002] During the use of the robot, for different processes, the robot needs to replace different tools. At present, the robots on the market usually use the manual replacement method of bolt connection when changing tools. [0003] However, the manual replacement method through bolted connection is not only labor-intensive, slow, and inefficient, but also there may be a risk of thread failure during multiple tightening processes. The bolt connection must use a wrench or rely on a manual knob. Both the wrench and the manual knob require a certain amount of space for operation. In a specific usage scenario, there may be a risk of interference, which will further affect the integration of the module, and the structure is not compact enough. It is very inconvenient for the robot to c...
