Full-automatic clamping mechanism oriented to large structural part

Abstract

The invention relates to a full-automatic clamping mechanism oriented to a large structural part. A six-degree-of-freedom robot is installed on a foundation through a base, the back face of a clampingbase plate is connected to an execution end of the six-degree-of-freedom robot through a transition flange, a ball screw is rotationally installed on the front face, and the two ends of the ball screw are in threaded connection with nuts; any end of the ball screw is connected with an output end of a power source; one ends of two clamping jaws are connected with the nuts through clamping moving plates and are driven by the power source to move in the opposite directions or in the same direction; and the clamping base plate is provided with a displacement sensor, a stop latch seat and a placement frame, proximity switches are arranged on the stop latch seat and the placement frame, one end of a sliding block frame of the displacement sensor is connected with the clamping moving plate connected with one end of any clamping jaw, and the other end of the sliding block frame of the displacement sensor is provided with a displacement sensor sliding block corresponding to the displacement sensor. According to the full-automatic clamping device, full-automatic clamping is achieved, the clamping state is automatically judged, the clamping force is adjustable, the clamping precision is high, and work is reliable.

Description

technical field [0001] The invention belongs to the field of aerospace vehicle engine assembly, in particular to a fully automatic clamping mechanism for large structural parts. Background technique [0002] The development of aerospace vehicles is the embodiment of a country's comprehensive national strength, and the high-precision assembly of aerospace vehicle engines is directly related to the success or failure of its launch and flight. There are widely heavy and large structural parts with spherical shell structures in the composition of aerospace vehicle engines. The correct clamping, transfer and attitude adjustment of such structural parts are the basis for ensuring their correct assembly. Therefore, the correct clamping, transfer, and attitude adjustment of the heavy and large structural parts with spherical shell structures in the aerospace vehicle engine are important guarantees for the assembly of the entire aerospace vehicle engine. [0003] For the clamping an...
