Multi-axis vertical screw-up device applied to aeroengine case and using method of multi-axis vertical screw-up device

Abstract

The invention discloses a multi-axis vertical screw-up device applied to an aeroengine case and a using method of the multi-axis vertical screw-up device. The multi-axis vertical screw-up device comprises a position regulating device and a screw-up device, wherein an indexing disc in the position regulating device is fixedly arranged on a workbench; the indexing disc is connected with a stand column through a stand column bracket; a mechanical arm sleeve is matched with a guide rail of the stand column; a balancer is fixedly arranged on the stand column, and a load end of the balancer is connected with the mechanical arm sleeve; a slide rod in the screw-up device is sleeved by a horizontal sleeve on the side surface of the mechanical arm sleeve, and is fixed by a fastening bolt arranged onthe horizontal sleeve; a clamp body is arranged on the slide rod; and a screw-up shaft and a displacement sensor are fixedly arranged on the clamp body. During working, the mechanical arm sleeve andthe slide rod separately regulate height and the horizontal distance of the screw-up shaft, so that the device is suitable for aeroengine cases of different types; and the displacement sensor measureslength deformation, in the screw-up process, of the bolt to obtain instant pre-tightening force of the bolt, so that torque of the screw-up shaft is regulated. The multi-axis vertical screw-up deviceimproves screw-up quality of the aeroengine case, and reduces technical requirements and labour intensity of a worker.

Description

technical field [0001] The invention belongs to the field of machinery, and relates to a tightening device, in particular to a multi-axis vertical tightening device applied to an aero-engine casing and a method of use thereof, for tightening bolts of the casing. Background technique [0002] The bolted connection structure is widely used in aero-engines because it is detachable, easy to overhaul, not limited by the thickness of the connected parts, and does not cause phase change of the connected materials. At present, the connection to the aircraft engine case is usually tightened by workers using a torque wrench, but manual tightening has the following problems: (1) The labor intensity of the workers is high, the technical level of the workers is high, and the production efficiency is low. (2) Use a torque wrench to tighten the bolts. Under the same torque, the discrete value of the bolt pre-tightening force is large, so it is not suitable to control the bolt pre-tightenin...
