Embodiment 1

[0053] The performance analysis platform of the transmission mechanism of the multi-link servo press in this embodiment is described by taking the transmission mechanism of the six-link servo press as an example. Select the transmission mechanism of the six-link servo press in the mechanism configuration analysis module, and then proceed according to the following process.

[0054] 1) Kinematic analysis

[0055] Taking the triangular toggle mechanism press as an example, the complex number vector method is used to solve the position, velocity and acceleration equations during the movement of the mechanism, and determine the trajectory.

[0056] L 1 ~ L 6 is the length of each rod, θ 1 is the crank angle θ 10 is the angle between the crank and the horizontal direction at the initial position, θi (i=2,3,4,5,6) represents the angle between the corresponding rods and the positive horizontal direction, r is the displacement of the slider,

Abstract

The invention relates to a multi-link servo press transmission mechanism performance analysis platform. The platform comprises a hardware part and a software part, wherein the hardware part comprisesa computer and a touch display screen; the software part comprises a mechanism conformation analysis module, a motion analysis module, a three-dimensional simulation analysis module, a stress analysismodule, an elastic analysis module, a scheme comparison module and a help module; and the software part is located in the computer. According to the platform, multi-link servo presses are taken as research objects, servo presses with different conformations are integrated, and performance analysis and scheme comparison are carried out on multi-link servo press transmission mechanism design results through an interface selection manner so as to promote and improve design decisions, so that designers can obtain simulation analysis of performance of link mechanisms after the link mechanism are designed, effective reference data required by research mechanisms is displayed for the users more intuitionally, convenience is brought to the optimization and research of mechanism schemes, each function module can be secondarily developed and conformation databases can be extended according to practical demands.

Description

technical field [0001] The invention belongs to the technical field of mechanical transmission design, and in particular relates to a performance analysis platform for a transmission mechanism of a multi-link servo press. Background technique [0002] Servo Press is a third-generation press that appeared internationally in the 1990s with a completely different concept from traditional mechanical presses. Based on the abandonment of energy-consuming components such as flywheels and clutches of traditional mechanical presses , the AC servo motor is used directly as the power source of the press, and the rotary motion of the motor is converted into the linear motion of the slider through multi-link actuators such as screw, crank connecting rod, and toggle rod. The multi-link servo press has the advantages of flexibility, high precision, high efficiency, and low noise, and has been widely used and promoted all over the world in recent years. Analyzing the configuration and perf...
