Abstract

The invention discloses a linear stretching device, comprising a base platform, an elastic mechanism, a power driving mechanism, a stretching mechanism and a guide mechanism; the power driving mechanism is connected with the stretching mechanism by the elastic mechanism, one end of the stretching mechanism is connected with a stretched object, the power driving mechanism controls the tensile force on the stretching mechanism by controlling the elastic deformation degree of the elastic mechanism, the guide mechanism comprises a track arranged below the stretching mechanism and one or more guide shafts fixed on the base platform, the stretching mechanism is connected with the track and the guide shaft(s), and the stretching direction of the power driving mechanism is parallel with the rack and the guide shaft(s). The linear stretching device disclosed by the invention is capable of accurately controlling the stretching length of the elastic part so as to convert the control over force delta F into the control over the stretching length of the elastic part by a motor. In addition, the stretching mechanism is enabled to move along the linear direction and a pulling plate does not deflect in the moving process due to the match between the track and the shaft(s), and forces of a plurality of force-applying points of the pulling plate on the stretched object can be uniform and consistent.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and relates to a stretching device, in particular to a linear stretching device. Background technique [0002] With the needs of the times, the development of instrument design in precision machinery is becoming more and more mature. Although the performance and functions of micro instruments manufactured so far are very powerful, the development of precision instruments is still inseparable from traditional machinery, because traditional There are still many desirable places in the machinery, such as design concepts, design methods and so on. [0003] The traditional method of providing external force is to directly provide external force to the object under force. The magnitude of the force directly applied is often difficult to control. For operations that require high precision, the difference in applied force has a great impact on the final result, and because the applied force ...
