Problems solved by technology

[0003] In the traditional electric clamping method, due to the rigidity of the metal material, the clamping force is very sensitive to the displacement of the clamping head, so the clamping head needs to always apply the required clamping force, which cannot meet the requirement of power-off after the clamping head is in place. The holding force is directly affected by the fluctuation of the motor current, and the accuracy of the holding force control is low

Abstract

The invention discloses an electric clamping device based on belleville springs. The electric clamping device comprises a first belleville spring shell, a second belleville spring shell and a belleville spring unit formed by assembling of the multiple belleville springs; the multiple belleville springs are stacked and can be deformed in the axial direction; two ends of the belleville spring unit are connected with a clamping tile and a pressure sensor through mechanical interfaces; the clamping tile is arranged at the end connected with a clamping target and is used for clamping and fastening the clamping target; the pressure sensor is fixed to a sensor connecting rod and is used for feeding back the size of the clamping force; the sensor connecting rod is installed on an output shaft of a linear motion component; and the linear motion component is connected with a motor through a speed reducer. According to the electric clamping device, the control precision of the clamping force on a workpiece is improved, damage to the clamped workpiece is reduced, the motor can be powered off after the workpiece is clamped in place, and the electric energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to an electric clamping device based on disc springs. Background technique [0002] In mechanical equipment, it is often necessary to clamp and fix the workpiece. The clamping methods can be hydraulic, pneumatic, mechanical and electric, of which electric is the most used. The electric type is characterized by convenient power supply, fast response, large driving force, convenient signal detection, transmission, and processing, and can adopt a variety of flexible control schemes. [0003] In the traditional electric clamping method, due to the rigidity of the metal material, the clamping force is very sensitive to the displacement of the clamping head, so the clamping head needs to always apply the required clamping force, which cannot meet the requirement of power-off after it is in place, and the clamping The holding force is directly affected by the fluctuation of t...
