Problems solved by technology

There are two types of gas cutting machines: mechanical and hydraulic. At present, most of the gas cutting machines are driven by hydraulic pressure. Since the hydraulic transmission uses hydraulic oil as the power transmission medium, there are the following problems: its starting performance is poor, and it is easy to cause internal Leakage occurs after the components are worn, and the leaked hydraulic oil will pollute the environment; the hydraulic oil is greatly affected by temperature, the overall efficiency is low, and sometimes there is noise and vibration
At present, there are few variable-degree-of-freedom mechanisms that can be applied to practical applications, and no variable-degree-of-freedom mechanisms that have been applied to gas cutting blanking machines have been seen.

Abstract

The invention discloses a servo driving connection rod type variable degree-of-movement mechanism for an oxygen-acetylene cutting machine. The servo driving connection rod type variable degree-of-movement mechanism comprises a base, a large arm telescopic mechanism, a lifting mechanism, a gripper connection rod luffing mechanism and gripper, a cutting gun, a servo driving device and two locking devices. The large arm telescopic mechanism comprises a first connection rod, a second connection rod and a third connection rod. One end of the first connection rod is connected with the base through a first rotary pair. The other end of the first connection rod is connected with one end of the third connection rod through a third rotary pair. The other end of the third connection rod is connected with the second connection rod through a fourth rotary pair. One end of the second connection rod is connected with the base through a second rotary pair. The other end of the second connection rod is connected with a large arm through a fifth rotary pair. The locking devices are installed on the rotary pairs. According to the servo driving connection rod type variable degree-of-movement mechanism, a connection rod transmission mechanism is adopted for replacing traditional hydraulic transmission, the defects that a hydraulic oxygen-acetylene cutting machine hydraulic system is complex and is liable to oil leakage can be overcome, and due to the fact that the locking devices are adopted on the rotary pairs, three-degree-of-freedom oxygen-acetylene cutting operation can be achieved through two driving rods.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a servo-driven link type variable activity mechanism for a gas cutting blanking machine. Background technique [0002] In the past few years, due to the shortage of personnel in the labor market, labor costs have increased year by year, which has promoted the wide application of gas cutting blanking machines in gas cutting blanking operations. There are two types of gas cutting machines: mechanical and hydraulic. At present, most of the gas cutting machines are driven by hydraulic pressure. Since the hydraulic transmission uses hydraulic oil as the power transmission medium, there are the following problems: its starting performance is poor, and it is easy to cause internal Leakage occurs after the components are worn, and the leaked hydraulic oil will pollute the environment; the hydraulic oil is greatly affected by temperature, the overall efficiency is low, and sometimes there is noise ...
