A simple gas cutting blanking machine adopting a variable-degree-of-freedom connecting rod mechanism is composed of a base 1, a big arm 2, a connecting piece 4, a wrist connecting rod 5, a cutting gun holder 27, a cutting gun 28, a driving device, a driving rod 13, a connecting rod 15, an upper arm 18, a first locking device 25 and a second locking device 26. The big arm 2 is connected to the base 1 through a first revolute pair 9. The other end of the big arm 2 is connected with the wrist connecting rod 5 through a third revolute pair 7. The first locking device 25 and the second locking device 26 are installed on an eighth revolute pair 17 and the first revolute pair 9 correspondingly. The driving device is composed of a first servo motor, is connected with the driving rod 13 and drives the driving rod 13. Both the first locking device 25 and the second locking device 26 are electromagnetic locking devices. The defect that an existing gas cutting blanking mechanical arm mechanism cannot carry out control until being provided with control motors with the number being equal to that of degrees of freedom of a connecting rod mechanism is overcome.
Description
technical field [0001] The invention relates to the field of mechanical technology, in particular to a simple gas cutting blanking machine using a variable degree of freedom link mechanism. Background technique [0002] At present, most of the general-purpose gas cutting cutting machines in the manufacturing industry are joint-type motor-driven manipulators with a series structure in the form of an open chain. Various actions of the manipulator. Since the driving motors of the joint-type manipulators with series structure in the form of open chain are installed at the joints, this structure has the following problems: the manipulator arm needs to carry the weight of the motor and meet the rigidity requirements, and the cross-sectional size of the arm needs to be made larger. This will increase the load on the drive motor, increase the moment of inertia of the arm, and lead to a decrease in the dynamic performance of the manipulator. At the same time, the drive motors are in...
