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 terminal ram 7 of the main motion mechanism of the planer is connected with a plane two-degree-of-freedom parallel diamond mechanism through the rod 6, and the ram 7 is the terminal output member of the whole mechanism. The planar two-degree-of-freedom parallel rhombus mechanism contains two identical kinematic branch chains. Rod 2 and rod 3 form the first kinematic branch chain. 11 are connected; the rod 4 and the rod 5 form the second kinematic branch chain, the rod 5 is connected with the frame 1 through the rotating pair 8, and the rod 5 is connected with the rod 4 through the rotating pair 9. The two identical kinematic branch chains are connected in parallel through the rotary pair 10, and the lengths of the rods 2, 3, 4 and 5 are the same. The planar two-degree-of-freedom parallel diamond mechanism is conne...

Abstract

The invention belongs to the field of mechanism and mechanical manufacture, and particularly relates to a novel main movement mechanism of a mechanical shaper. The main movement mechanism is characterized in that a ram of the main movement mechanism of the shaper is connected with a planar two-freedom-degree parallel rhombohedral mechanism through a connecting rod, the planar two-freedom-degree parallel rhombohedral mechanism is composed of two same movement branch chains, all connecting rods of the planar two-freedom-degree parallel rhombohedral mechanism have the same length, and each branch chain is driven by a servo motor. Input of the servo motors is transmitted, combined and converted into single high-power output of the ram of the main movement mechanism of the shaper through the planar two-freedom-degree parallel rhombohedral mechanism. The planar two-freedom-degree parallel rhombohedral mechanism has the mechanical coordination function and can eliminate movement interference caused by input errors of the servo motors and reduce the control difficulty. The main movement mechanism has the advantages of controllability, flexibility and intelligentization.

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 novel 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 ...
