Robot joint quick-replacing device

Abstract

The invention discloses a robot joint quick-replacing device. The robot joint quick-replacing device comprises a driving device, a locking shell, a locking end main body and steel balls; the output end of the driving device is connected with the locking shell so that the locking shell can be driven to go up and down; the locking end main body is slidably arranged in the locking shell; the steel balls are arranged in locking grooves of the locking end main body; and the locking shell is internally provided with a conical groove for installing the steel balls in a clamped mode. According to therobot joint quick-replacing device provided by the invention, the locking shell and the locking end main body are driven by the driving device to do vertical motion, the steel balls are guided and aligned to the conical groove and the locking grooves, and the purpose of quickly replacing an end effector is achieved; and in the process, a screw rod stepping motor simple in structure is introduced,vertical motion of the locking shell is achieved through spiral transmission, accordingly, the quick replacing function is achieved, the quick replacing butt-joint structure is optimized, and the replacing efficiency of the end effector is improved.

Description

technical field [0001] The invention relates to the technical field of collaborative robots, in particular to a robot quick-change joint device. Background technique [0002] Collaborative robots are robots that can interact closely with humans in a common space. Compared with traditional industrial robots, they have extremely high safety and flexibility. Collaborative robots will also have certain market competitiveness in the robot market. [0003] The execution of collaborative robot tasks is inseparable from a variety of end effectors. The replacement of these end effectors is often done manually. When performing multi-process operations, the next step is often performed by manually replacing the end effectors. , or adding multiple robots to achieve different functions, which will not only increase the manufacturing cost, but also reduce the working efficiency and impose strict requirements on the working space. The structure of the end effector quick change device is v...

[0003] The execution of collaborative robot tasks is inseparable from a variety of end effectors. The replacement of these end effectors is often done manually. When performing multi-process operations, the next step is often performed by manually replacing the end effectors. , or adding multiple robots to achieve different functions, which will not only increase the manufacturing cost, but also reduce the working efficiency and impose strict requirements on the working space

The structure of the end effector quick change device is various, which can meet the end effector quick change tasks in special environments such as welding. At present, there are more pneumatic and hydraulic quick change mechanisms on the market. Domestic collaborative robots and quick change The technology is still in its infancy, so that there is no electric quick-change device suitable for collaborative robots. The existing known electric quick-change devices for collaborative robots use a more complicated gear mechanism, and use multiple gears to achieve transmission.

In terms of the quick-change working mode of collaborative robots, the structure is more complicated and requires more manufacturing and maintenance costs.
