Problems solved by technology

This requires that multiple parallel low-power servo motors must meet the input synchronization, otherwise it will cause motion interference, and even damage the servo motor and planer in severe cases.
However, requiring strict synchronous input of multiple servo motors will undoubtedly increase the difficulty of control

Embodiment Construction

[0010] The following is attached figure 1 The illustrated embodiment further details the present invention:

[0011] Such as figure 1 In the shown embodiment: the ram (rod 10) of the main motion mechanism of a mechanical planer is connected to the motion platform (rod 4) of a plane three-degree-of-freedom parallel mechanism through a rod 9, and the ram (rod 10) is a mechanism Integral terminal output member. The planar three-degree-of-freedom parallel mechanism contains three identical kinematic branch chains, and is a symmetrical structure. The rod 2 and the rod 3 form the first kinematic branch chain. The rod 2 is connected with the frame 1 through the rotating pair 11. 3 is connected through the rotating pair 12, the rod 3 and the rod 4 (the motion platform of the planar three-degree-of-freedom parallel mechanism) are connected through the rotating pair 13; the rod 5 and the rod 6 form the second motion branch chain, and the rod 6 and the frame 1 The rotating pair 16 is ...

Abstract

The invention belongs to the field of the theory of mechanism and machine manufacturing, and particularly relates to a three-input main motion mechanism of a mechanical shaping machine. The three-input main motion mechanism of the mechanical shaping machine is characterized in that a ram of the main motion mechanism of the shaping machine is connected with a motion platform of a planar three-degree-of-freedom parallel mechanism through a connecting rod, the planar three-degree-of-freedom parallel mechanism is composed of three same motion branched chains and is of a symmetrical structure, and each branched chain is driven by a servo motor. The planar three-degree-of-freedom parallel mechanism transmits, synthesizes and converts inputs of the three sets of servo motors into a single high-power output of the ram of the main motion mechanism of the shaping machine. The planar three-degree-of-freedom parallel mechanism has a mechanical coordination function, motion interference caused by input errors of the three sets of servo motors can be eliminated, and control difficulty is lowered. The three-input main motion mechanism of the mechanical shaping machine has the advantages of controllability, flexibility and intelligence.

Description

Technical field: [0001] The invention belongs to the field of mechanics and machine manufacturing, in particular to a main motion mechanism of a three-input mechanical planer. Background technique: [0002] Bullhead planer can be applied to the planing process of horizontal plane, vertical plane, inclined plane, straight groove, V-shaped groove, dovetail groove and straight generatrix forming surface, so it is widely used in the field of machinery manufacturing. In order to improve the quality of the machined surface, the ram should be required to move at a constant speed, but the main movement mechanism of the mechanical bull planer generally adopts a combined mechanism composed of a swing guide mechanism and a swing rod slider mechanism connected in series. The movement is a non-uniform movement, which brings difficulties to further improve the processing quality. [0003] In order to solve the above problems, the mechanism active control method proposed by some scholars ...
