Abstract
The utility model discloses a mounting structure for driving a large arm, which is an evolved swinging guide-rod mechanism, wherein the structure of the swinging guide-rod mechanism is characterized in that a frame used for mounting the large arm is fixed with an upper hinge support and a lower hinge support; the upper hinge support is hinged with a crutch handle; the front end of the crutch handle is fixedly connected with the body of a linear stepping motor; the screw rod of the linear stepping motor is screwed with a nut block; the nut block is provided with a hinge; an upper cranking rod is hinged by hinges on the lower hinge support and the nut block; and the crutch handle and the linear stepping motor form the swing guide-rod component of the evolved swinging guide-rod mechanism. The utility model adopts a novel driving mode and structural mode for outward extension movement of the large arm, which has compact structure, large output moment, and high transmission efficiency without motion interference.
Description
Technical field
The utility model relates to the drive installation structure of a kind of robot ' s arm or the big arm of artificial limb.
Background technology
At present, in the design of robot ' s arm structure or the big arm configuration of artificial limb, adopt various drives structure to realize abduction exercise under the big arm load condition.Because the appearance and size of big arm can not design very greatly, and certain bio-imitability be arranged, so, how in limited structure space, to realize the efficient abduction that big arm has under the certain loading condition is driven, 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 big arm drive installation structure for addressing the above problem.
For reaching above-mentioned purpose, big arm drive installation structure of the present utility model is a kind of oscillating guidebar mechanism of evolution, and the structure of this oscillating guidebar mechanism is: be fixed with upper hinge bearing and following rocker bar bearing on the frame that big arm is installed; Be hinged with on the upper hinge bearing and turn handle, turn the handle front end and be fixed on the body of linear stepping motor, the nut block that spins on the linear stepping motor screw rod is provided with hinge on nut block, by the hinged rocking bar of going up of the hinge on following rocker bar bearing and the nut block.Turn the pendulum guide rod member of the oscillating guidebar mechanism of handle and linear stepping motor formation evolution.
When linear stepping motor was worked, its screw rod rotated and drives nut block and moves forward and backward along screw rod, and then drove the swing of pendulum guide rod member, realized the abduction exercise of big arm with this.
Advantage of the present utility model is: adopted a kind of type of drive and frame mode of novel big arm abduction exercise, and its compact conformation, output torque is big, and the transmission efficiency height can not move interference.
Description of drawings
Fig. 1 is the principle schematic of big arm abduction drive installation structure, and wherein Fig. 1 a is the state of big arm when being in initial position, and Fig. 1 b is the state of big arm abduction during to horizontal level.
Marginal data: rocker bar bearing 3--turns handle 4--linear stepping motor body 5--linear stepping motor screw rod 6--nut block 7--rocking bar 8--hinge under the 1--upper hinge bearing 2--.
The specific embodiment
The principle of big arm abduction drive installation structure of the present utility model as shown in Figure 1.
Big arm drive installation structure of the present utility model is a kind of oscillating guidebar mechanism of evolution, and its structure is: install on the frame of big arm be fixed with upper hinge bearing 1 and play rocker bar bearing 2, be hinged with on the upper hinge bearing 1 turn handle 3, turn that handle 3 front ends are fixed on the body 4 of linear stepping motor, the nut block 6 that spins on the linear stepping motor screw rod 5, passing through between nut block 6 and the following rocker bar bearing 2 hinge 8 hinged on rocking bar 7.Turn handle 3, be cemented in the linear stepping motor body 4 that turns the handle front end and the linear stepping motor screw rod 5 that rotates constitutes the pendulum guide rod member of the oscillating guidebar mechanism that develops.When linear stepping motor was worked, its screw rod 5 rotated and drives nut block 6 and moves forward and backward along screw rod 5, and then drives the swing of pendulum guide rod member, realizes the abduction exercise of big arm with this.
