Industrial waste grabbing operation method using servo motor driven multi-degree-of-freedom simple connecting rod mechanism

Abstract

The invention discloses an industrial waste grabbing operation method using a servo motor driven multi-degree-of-freedom simple connecting rod mechanism. The method is characterized in that the servomotor driven multi-degree-of-freedom simple connecting rod mechanism comprises a base 9, a first driving rod 1, a second driving rod 2 , a third driving rod 3, a third connecting rod 4, a fourth connecting rod 7, a first connecting rod 5, a big arm 6 and a servo driving device, wherein one end of the first driving rod 1 is connected with the base 9 through a first rotating pair 11, and the other end of the first driving rod 1 is connected with the third connecting rod 4 through a fourth rotating pair 14; the other end of the third connecting rod 4 is connected with the first connecting rod 5 through a fifth rotating pair 15; one end of the second driving rod 2 is connected with the base 9 through a second rotating pair 12; the servo driving device comprises a first servo motor, a second servo motor and a third servo motor which are connected with the first driving rod 1, the second driving rod 2 and the third driving rod 3 respectively so as to drive the first driving rod 1, the seconddriving rod 2 and the third driving rod 3 to rotate. According to the method, the electric motor is installed on the base, so that the problems that an arm of a chain opening mechanism is large in weight and dynamic performance is poor are solved.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a method for grasping and loading industrial waste by using a simple multi-degree-of-freedom linkage mechanism driven by a servo motor. Background technique [0002] Due to the shortage of personnel in the labor market, the increase in labor costs year by year and the enhancement of enterprises' awareness of labor protection have promoted the wide application of industrial waste grabbing machines in industrial waste grabbing and loading operations. There are two types of industrial waste grabbing machines: mechanical and hydraulic. At present, most of the mechanical arms of industrial waste grabbing machines are driven by hydraulic pressure. Since hydraulic transmission uses hydraulic oil as the medium for power transmission, there are the following problems: its starting performance is poor, It is easy to leak due to the wear of internal components, and the leaked hydraulic oil will pol...

Problems solved by technology

There are two types of industrial waste grabbing machines: mechanical and hydraulic. At present, most of the mechanical arms of industrial waste grabbing machines are driven by hydraulic pressure. Since hydraulic transmission uses hydraulic oil as the medium for power transmission, there are the following problems: its starting performance is poor, It is easy to leak due to the wear of internal components, 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

Sometimes there will be overheating, weak work and other phenomena; hydraulic components require high machining accuracy, strict assembly requirements, difficult manufacturing, and high technical maintenance requirements during use.

With the increase of the functions of the industrial waste grabbing machine, its hydraulic system is becoming more and more complex, and the failure is more sudden and hidden

The mechanical industrial waste grabbing machine uses mechanical transmission parts to realize the industrial waste grabbing action. It has the advantages of firmness and durability. However, the traditional single-degree-of-freedom mechanical industrial waste grabbing machine cannot complete complex actions, and its application range is very limited. The mechanical type can The control mechanism electric industrial waste grabbing machine replaces the hydraulic transmission with a connecting rod mechanism. When the active rod is driven by a servo motor, it is easy to realize automation and numerical control, which solves some shortcomings of the hydraulic system.
