Abstract
The utility model discloses a driving and installing structure for an elbow joint, which is an evolved swing guide rod mechanism. The driving and installing structure comprises an upper arm, a forearm and a through-going type linear stepping motor, wherein the upper arm and the forearm are hinged together through an elbow hinge; an upper hinge support is arranged on the upper arm; a lower hinge support is arranged on the forearm; the motor body of the through-going type linear stepping motor is hinged on the upper hinge support of the upper arm; and the front end of a screw rod of the through-going type linear stepping motor is hinged on the lower hinge support of the forearm. The driving and installing structure adopts novel forearm elbow driving means and structure means, has compact structure, large output torque and high transmission efficiency, and does not cause motion interference.
Description
Technical field
The utility model relates to a kind of elbow joint drive installation structure that can be used for robot forearm or artificial limb forearm.
Background technology
At present, on little arm configuration of robot or artificial limb forearm structure Design, adopt various drives structure to realize bending and the stretching of forearm under load condition.Because the monnolithic case size of forearm can not design very greatly, and certain bio-imitability be arranged, so, how to realize in limited structure space that forearm is had high efficiency drive under the certain loading condition, be the problem that those skilled in the art need solve.
The utility model content
The purpose of this utility model is to provide a kind of forearm elbow joint drive installation structure for addressing the above problem.
For reaching above-mentioned purpose, forearm elbow joint drive installation structure of the present utility model is a kind of oscillating guidebar mechanism of evolution, is made up of big arm, forearm and through linear stepping motor; Wherein, big arm and forearm are hinged with elbow hinge, big arm is provided with the upper hinge bearing; forearm is provided with down rocker bar bearing; the body of through linear stepping motor is hinged on the upper hinge bearing of big arm, and the screw front end of through linear stepping motor is hinged on the following rocker bar bearing of forearm.
When the work of through linear stepping motor, screw rod is realized moving forward and backward in the motor body, and then the drive forearm rotates around elbow hinge, realizes the bending and the stretching routine of forearm with this.
Advantage of the present utility model is: adopted a kind of novel forearm elbow joint type of drive and frame mode, and its compact conformation, output torque is big, and the transmission efficiency height can not move interference.

Fig. 1 .b is the principle schematic of the utility model forearm when being in certain movement position.
The big arm of marginal data: 1--; The 2--forearm; The body of 3--linear stepping motor; 4--upper hinge bearing; The screw rod of 5--linear stepping motor; Rocker bar bearing under the 6--; The 7--elbow hinge.
The specific embodiment
The principle of forearm elbow joint drive installation structure of the present utility model as shown in Figure 1.
Forearm elbow joint drive installation structure of the present utility model is a kind of oscillating guidebar mechanism of evolution, is made up of big arm 1, forearm 2 and through linear stepping motor; Wherein, big arm 1 and forearm 2 usefulness elbow hinges 7 are hinged, big arm 1 is provided with upper hinge bearing 4; forearm 2 is provided with down rocker bar bearing 6; body 3 of through linear stepping motor is hinged on the upper hinge bearing 4 of big arm 1, and screw rod 5 front ends of through linear stepping motor are hinged on the following rocker bar bearing 6 of forearm 2.
When through linear stepping motor was worked, screw rod 5 was realized moving forward and backward in the body 3 of motor, and then drove forearm 2 around elbow hinge 7 rotations, realized the bending and the stretching routine of forearm 2 with this.
