Abstract

The invention relates to a rotating arm type mechanical hand, which comprises a base, a rotating seat, a first mechanical arm, a second mechanical arm and a clamping jaw, wherein the rotating seat is rotationally connected onto the base and is in coaxial arrangement with the base, the first mechanical arm is rotationally connected onto the rotating seat, a rotating shaft of the first mechanical arm is vertical to a rotating shaft of the rotating seat, the second mechanical arm is rotationally connected onto the first mechanical arm and is in arrangement parallel to the rotating shaft of the base, and the clamping jaw is fixed on the lower end of the second mechanical arm. The mechanical hand has the advantages that the linear displacement mode and the rotating displacement mode are combined, the mechanical arm displacement blind region is eliminated, and the flexibility of the mechanical arm is improved.

Description

Swing-arm type mechanical arm

Technical field

The present invention relates to the manipulator field, particularly a kind of swing-arm type mechanical arm.

Background technology

Existing manipulator is mostly by linear displacement repeatedly or realize displacement by multistage rotation, but the manipulator course of moving by above-mentioned two kinds of modes and stroke limitation comparatively all can produce certain blind area.

Summary of the invention

The purpose of this invention is to provide a kind of swing-arm type mechanical arm without the stroke blind area.

For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of swing-arm type mechanical arm, it comprises base, be rotationally connected with on described base and with the rotating seat of the coaxial setting of base, be rotationally connected with on described rotating seat and the first mechanical arm that the rotating shaft of rotating shaft and described rotating seat is perpendicular, be slidably connected on described the first mechanical arm and be parallel to second mechanical arm of rotating shaft setting of described base and the jaw that is fixed on described the second mechanical arm lower end.

Optimize, described rotating seat, the first mechanical arm and the second mechanical arm have respectively driven by servomotor.

Beneficial effect of the present invention is: manipulator of the present invention combines the linear displacement mode with the swing offset mode, has eliminated mechanical arm displacement blind area, the flexibility that has improved mechanical arm.

The accompanying drawing explanation

Accompanying drawing 1 is structural representation of the present invention;

In accompanying drawing: 1, base; 2, rotating seat; 3, the first mechanical arm; 4, the second mechanical arm; 5, jaw.

The specific embodiment

Below in conjunction with embodiment shown in the drawings, the present invention is described in detail below:
