Locking mechanism

Abstract

The invention provides a locking mechanism. The locking mechanism comprises a robot end and a tool end, wherein the robot end comprises a first shell, a thrust inclined surface, a piston cover part, an upper sealing cover and a ball; a guide column is arranged in the first shell; the piston cover part sleeves the guide column, and a locking action end is arranged at the bottom of the piston coverpart; the guide column is connected with the upper sealing cover; the thrust inclined surface is mounted on the first shell; a mounting through hole and a locking space are formed in the locking action end; one end of the ball is mounted in a second accommodating space, and the other end of the ball can penetrate through the mounting through hole and extends into the locking space; a pull nail isarranged on the tool end, and a locking force bearing end is arranged on the pull nail; and the locking force bearing end can be mounted in the locking space in a matched manner. The locking mechanismcan realize a reliable locking connection function, can provide stable active separation acting force to realize reliable separation, and is simple in structure and accurate in operation.

Description

technical field [0001] The present invention relates to the field of locking mechanisms, in particular to a locking mechanism. Background technique [0002] Robot technology is widely used in life and production. Most of the current robots are used in specific occasions and have a fixed configuration, which restricts the promotion and application of robots in multiple fields. The modularization of robots is the trend of robot research and development in the world today. By installing different tool ends on the robot end, the function and use of the robot can be expanded. However, there are many problems in the installation and disassembly of the tool end and the robot end in the prior art. The locking operation is inconvenient, the locking is not firm, the control precision is not high, and the structure is complicated, which greatly limits the expansion of the robot's functional use.

The modularization of robots is the trend of robot research and development in the world today. By installing different tool ends on the robot end, the function and use of the robot can be expanded. However, there are many problems in the installation and disassembly of the tool end and the robot end in the prior art. The locking operation is inconvenient, the locking is not firm, the control precision is not high, and the structure is complicated, which greatly limits the expansion of the robot's function and use.

[0003] Patent document CN204658462U discloses a robot quick-change tool device, including a robot end body and a tool end body. The robot end body is connected to the tool end body. The tightening device locks and assembles the body of the robot end on the body of the tool end, but in this design, after the piston is retracted, the connecting steel ball remains in the position where it fits the tool end. During the movement, relying on the self-weight of the tool end, the locking inclined surface pushes back the steel ball to recover, realizing the separation between the robot end and the tool end; this structure is easy to cause the locking inclined surface of the tool end to push back the steel ball due to the wear of the steel ball slot at the robot end. Failure of ball recovery process, causing separation failure
