Description

External manipulator structure of machine tool Technical Field The utility model relates to the technical field of machine tool manipulators, in particular to an external manipulator structure of a machine tool. Background The numerical control machine is an automatic machine equipped with a program control system, and can operate the machine and machine parts according to a programmed program. The numerical control machine tool integrates the technologies of machinery, automation, computers, microelectronics and the like, solves the processing problems of complex, precise and small-batch parts, and is a flexible and high-efficiency automatic machine tool. External manipulators are required to be used in some numerical control machine tools. In the prior art, because the parts that the digit control machine tool can process are various, when processing the part of different shapes, need change the gripper that can form a complete set and be suitable for generally, however, current gripper adopts a large amount of bolts to fix at the arm end mostly, when changing the gripper, need frequent dismouting bolt, leads to the operation very troublesome, influences the change efficiency of gripper. Therefore, we propose an external manipulator structure of lathe. Disclosure of utility model (One) solving the technical problems Aiming at the defects of the prior art, the utility model provides an external manipulator structure of a machine tool, which solves the problems that the prior mechanical claw is mostly fixed at the tail end of a mechanical arm by adopting a large number of bolts, and the bolts are required to be frequently disassembled and assembled when the mechanical claw is replaced, so that the operation is very troublesome and the replacement efficiency of the mechanical claw is affected.
