Embodiment 1

[0017] A stretching device capable of real-time control of tension is provided, including a base, a control system, a driver, an induction device, an elastic member and an external interface mechanism, the driver is fixed on the base, the pull rod of the driver is connected to one end of the induction device, and the induction device The other end is connected to one end of the spring, the other end of the spring is connected to the external interface mechanism, and the sensor is connected to the control system. During the movement of the stretching device, the sensing device converts the stretching force into an electrical signal and feeds it back to the control system in time. The system controls the motion state of the motor in real time through the feedback information, thereby controlling the stretching force of the stretching device.

[0018] figure 1 As shown, it is a structural block diagram of the present invention, which includes: a driver 1, an induction device 2, a...

Embodiment 2

[0021] figure 2 Shown is the specific embodiment of the present invention, each component and embodiment 1 figure 1 same. The driver 1 is a linear motor 1a, which can drive the movement of the stretching device through the control of the control system; the induction device 2 is a tension sensor 2a, which can convert the tension signal into an electrical signal and transmit it to the control system in time. system; the elastic member is a spring or a flexible hinge that satisfies Hooke’s law, that is, the component 3a in the figure, which plays a force transmission role in the stretching process of the stretching device, and at the same time due to the elasticity The flexibility of the parts can protect the motor, tension sensor and other components during the movement of the device, and prevent the device from being damaged by the hard force; the external interface mechanism of the stretching device matches the interface of the corresponding object to be stretched , the ex...

Abstract

The invention relates to an accurate control stretching device and mainly solves problems in the prior art that external force is directly exerted on stressed objects, strength of directly exerted force is normally difficult to control, and force application difference greatly influences the final result for operations having high accuracy requirements. The accurate control stretching device comprises a control system, a driver, a sensing device, an elastic part, an external interface mechanism and the like and is characterized in that the stretching device can accurately provide a definite tension force for outside objects through an interface and can timely control next operation of the driver according to tension force information fed back by the sensing device, the problems are well solved, and the accurate control stretching device can be used in measurement and other operations.

Description

[0001] technical field [0002] The present invention relates to an accurately controlled stretching device. Background technique [0003] 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 a lot of desirable places in the machinery, such as design concepts, design methods and so on. During the use of many instruments, especially when it comes to operations such as measurement, there are strict requirements on the flatness and other elements of the operating object. Therefore, when this type of operation is involved, it is necessary to provide certain tension force. [0004] The traditional method of providing external pulling force is to directly provide external force to the obje...
