Embodiment Construction

[0043] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0044] Specific embodiments of the telescopic drive device for mechanical joints provided by the present invention:

[0045] like Figure 1 to Figure 9 As shown, the telescopic drive device for mechanical joints includes a first hinge seat 1, a first transmission link 2, an intermediate hinge seat 9, a second transmission link 10 and a second hinge seat 11. The telescopic directions of the joint telescopic drive device are arranged in sequence; the first hinge seat 1 and the second hinge seat 11 are used for hinged connection with the two joint bodies of the mechanical joint respectively, so that the first hinge seat 1 and the second hinge seat 11 are close to each other. Or drive the two joint bodies to swing relative to each other when they are far away.

[0046] like figure 1 As shown, there are four first transmission links 2 evenly distributed ...

Abstract

The invention belongs to the technical field of mechanical joints, and in particular relates to a mechanical joint and its driving device. When using the device, the first and second hinge seats are respectively hinged on the two joint bodies of the mechanical joint. When the device is expanded, the motor rotates clockwise. Rotation, the motor seat and the first hinge seat cooperate with each other to prevent rotation, the rotating arm pulls the driving link to perform a circular and centripetal mixed movement of inward shrinkage, and the driving link then pulls the middle hinge seat to radially contract the rotating arm, and the middle hinge seat The angle between the hinged first transmission link and the second transmission link gradually increases, the motor seat will be guided away from the first hinge seat in the telescopic direction, and the first hinge seat and the second hinge seat are away from each other, so that the device shaft When the device is contracted, it does the opposite movement when it is expanded; it avoids the direct drive of the motor, which reduces the cost of use, and the mechanical transmission between the hinged links makes the drive device respond quickly and act more accurately. .

Description

technical field [0001] The invention belongs to the technical field of mechanical joints, and in particular relates to a mechanical shutdown and a driving device thereof. Background technique [0002] At present, most of the current mechanical joints are driven directly by servo motors, which have high torque requirements for servo motors, and such servo motors are often costly; in addition to the direct drive of servo motors, there are also some mechanical joints that use Pneumatic or hydraulic drive, which requires the use of elastic media such as compressed air or hydraulic oil. When using this kind of elastic media that can buffer to drive mechanical joints, it will cause the mechanical joints to respond slowly and move in time, as well as inaccurate positioning. The problem. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a telescopic drive device for a mechanical joint, so as to solve the technical problems of the high cost of th...
