Abstract

The invention belongs to servo mechanisms, and particularly relates to an efficient high-precision two-finger clamping device with a power-loss keeping function. The efficient high-precision two-finger clamping device comprises a composite planetary roller lead screw transmission system, a power transmission system and a shell assembly. A lead screw, a left-handed nut assembly and a right-handed nut assembly are arranged in the composite planetary roller lead screw transmission system. The lead screw converts the rotation motion of the power transmission system into the left-handed nut assembly and the right-handed nut assembly moving linearly toward each other along the lead screw. The power transmission system provides power for transmission and motor position information. The efficienthigh-precision two-finger clamping device is compact in structure, large in clamping force, and high in transmission efficiency and positioning precision.

Description

technical field [0001] The invention belongs to a servo mechanism, in particular to an industrial two-finger clamping device. Background technique [0002] The two-finger clamping device is an execution unit widely used in the industrial field. It is usually installed at the end of the robot and in the automated production line to clamp and fix objects. At present, the most widely used clamping device in the market is the pneumatic clamp. Although it has the advantages of light weight and fast execution speed, it also has the disadvantages of small clamping force, poor precision, and complicated supporting equipment; while traditional electric clamps often use linear motors, Trapezoidal screw or connecting rod transmission forms lead to problems such as large volume, low efficiency, and complex structure, which are often limited in practical applications. In order to shorten the production cycle and meet higher application requirements, it is particularly necessary to devel...
