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 moving 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 kinematic branch chain, and the rod 6 and the frame The rotating pair 16 is c...

Abstract

The invention belongs to the fields of mechanism theory and machine manufacturing, and particularly relates to a three-servo-motor parallel input mechanical shaper main movement mechanism. The three-servo-motor parallel input mechanical shaper main movement mechanism is characterized in that a ram of the shaper main movement mechanism is connected with a motion platform of a planar three-freedom-degree parallel mechanism through a connecting rod, the planar three-freedom-degree parallel mechanism is formed by three identical motion branch chains and is of a symmetrical structure, and each branch chain is an RPR (R represents a revolute pair and P represents a prismatic pair) branch chain and driven by a servo motor; the input of the three servo motors is transmitted, synthesized and converted into the single high-power output of the ram of the shaper main movement mechanism by the planar three-freedom-degree parallel mechanism; the planar three-freedom-degree parallel mechanism has a mechanical coordination function and can eliminate the motion interference caused by input errors of the three servo motors and lower control difficulty. The three-servo-motor parallel input mechanical shaper main movement mechanism has the advantages of being controllable, flexible and intelligent.

Description

Technical field: [0001] The invention belongs to the field of mechanics and mechanical manufacturing, and in particular relates to a main motion mechanism of a mechanical planer with three servo motors connected in parallel. 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...
