Abstract

The invention relates to a clamping device for a small-sized rod-type elastic part. The clamping device comprises a V-shaped groove clamping block, a pillar-shaped support base (9) and a door-opening type clamping base, wherein the V-shaped groove clamping block is internally provided with at least two V-shaped grooves of different sizes for clamping elastic rod-type parts of different specifications and different sizes; the pillar-shaped support base (9) is arranged on the lower part of the V-shaped groove clamping block for fixing the V-shaped groove clamping block and regulating the positions of the elastic rod-type parts in the V-shaped groove clamping block; the door-opening type clamping base is arranged on the lower part of the pillar-shaped support base for fixing the pillar-shaped support base (9), and regulating the position of the pillar-shaped support base (9). Compared with the prior art, the clamping device has the advantages of simple structure, stable clamping, convenience in use and the like.

Description

technical field [0001] The invention relates to a clamping device, in particular to a clamping device for a small rod type elastic part. Background technique [0002] As one of the main power sources and energy transfer units, the electro-hydraulic system is widely used in the field of industrial control. In this system, the electrohydraulic servo valve is the main control unit. The performance of the torque motor composed of electromagnetic elements, elastic elements and fluid determines the control accuracy of this type of servo valve. Small and precise elastic components in torque motors are used as force sensitive devices to obtain feedback control signals. The stiffness characteristic of the elastic element has an important influence on the performance of the electro-hydraulic servo valve, and this characteristic determines the performance indicators such as control accuracy and sensitivity of the electro-hydraulic servo valve. [0003] During the design process of t...
