An electric push-pull mechanism

Abstract

The invention discloses an electric push-and-pull mechanism which comprises a connecting rod, a left pressing block, a right pressing block, a left pressure sensor, a right pressure sensor, wherein the connecting rod is used for pushing and pulling a sliding table to move, and the left pressing block, the right pressing block, the left pressure sensor and the right pressure sensor are arranged on two sides of the connecting rod. When a head of an electric push-and-pull rod extends, the left pressing block is pushed and pressed by the head and acts on the left pressure sensor, the connecting rod is pushed by generated pressure, and a workpiece is compressed. When the head of the electric push-and-pull rod contracts, the head pulls the right pressing block through a sliding rod, the right pressing block acts on the right pressure sensor, the connecting rod is pulled leftwards by generated pressure, and the workpiece is stretched. According to the electric push-and-pull mechanism, by the aid of a combined structure of the electric push-and-pull rod and the pressure sensors, and pushing and pressing functions and pressure control of the mechanism are achieved, so that products are stably pushed and pulled. Compared with a traditional push-and-pull mechanism, the electric push-and-pull mechanism is simple in structure, easy to operate, high in pressure control accuracy and applicable to the field of optical fiber tension and compression devices.

Description

technical field [0001] The invention relates to the field of optical fiber stretching and compression equipment, in particular to an electric push-pull mechanism. Background technique [0002] At present, the push-pull mechanism is mainly used for stretching and compressing the product. The traditional push-pull methods include hanging heavy objects, pneumatic and hydraulic. [0003] Suspended heavy object type: It is to hang certain heavy objects, connected by ropes, and mechanically stretched by the action of object gravity. Its operation is not flexible, the work intensity is high, and the tension adjustment is inconvenient. [0004] Pneumatic type: using compressed gas as the working medium, relying on the pressure of the gas to transmit power, the compressed gas is delivered to the pneumatic actuator through the pipeline and the control valve, and the pressure energy of the compressed gas is converted into mechanical energy to do work. Due to the high compressibility of...
