Annular bar rotating and clamping device

Abstract

The invention relates to an annular bar rotating and clamping device which mainly includes a ferrule-shaped fetching rack. An annular rotary frame is installed inside the fetching rack in a rotating mode and provided with an inner gear ring and an outer gear ring engaged with a transmission gear. The transmission gear is connected with a motor. The inner gear ring is engaged with six pinions distributed annularly, each pinion is connected with a rotary shaft, and the lower end of each rotary shaft is connected with an arc-shaped adapting plate. Each adapting plate is connected with a main clamping plate. Each clamping plate is provided with four arc surfaces, and all the main clamping plates can be spliced into one integral ring. The annular bar rotating and clamping device is high in degree of automation, and the multiple main clamping plates can be driven to synchronously move towards the center in a rotating mode, so that bars are clamped and fixed. Accordingly, the annular bar rotating and clamping device can effectively assist the arms of a robot in grabbing, and is convenient to operate.

Description

technical field [0001] The invention relates to the field of automatic robot matching equipment, in particular to a circular rotating clamping device for bars. Background technique [0002] Generally speaking, the temperature of the heated bar is too high for people to grab it with bare hands. Although the long-handled clamp can be used for manual auxiliary clamping, the long-handled clamp has better thermal conductivity and the temperature of the bar Too high, even if people use long-handled clamps to grip, they will cause some burns to the hands. Therefore, most processing workshops have begun to introduce robot arms to grab the bar, but because the surface of the bar is relatively smooth, It is difficult for the equipment installed at the end of the robot arm to effectively grip the bar. Contents of the invention [0003] Aiming at the defects of the above-mentioned technologies, the present invention proposes a bar circular rotating clamping device which is installed ...
