Abstract

The invention relates to a tightening machine, in particular to the tightening of large threads between different sections of a projectile and a small-caliber missile. The tightening machine includesa rack, a tightening unit, a clamping unit, a lifting slide table and a lifting drive mechanism, wherein the lifting slide table is slidably connected to the rack, the lifting drive mechanism is arranged on the rack and connected with the lifting slide table, and the clamping unit or the tightening unit is arranged on the lifting slide table; when the clamping unit is disposed on the lifting slidetable, the tightening unit is fixed to the upper end of the rack; when the tightening unit is disposed on the lifting slide table, the clamping unit is disposed on a transmission line body, and the tightening unit and the clamping unit achieve the tightening of a workpiece by mutual cooperation. The automatic tightening machine can realize automatic tightening and solve the problems of high laborintensity, low work efficiency and certain risk in the existing tightening process. The automatic tightening machine has the advantages of compact structure, reasonable layout and wide adaptability,and can be used for direct operation in a product pallet station of a production line.

Description

technical field [0001] The invention belongs to the technical field of body assembly, and in particular relates to an automatic screwing machine. Background technique [0002] During the assembly process of artillery shells and small-caliber missiles, different compartments such as the seeker, warhead, control cabin, and engine need to be tightened and combined, and there are tightening torque requirements. The existing tightening process is generally to move the product away from the transmission line body, manually install the tightening tooling, pre-tighten, and then perform automatic or manual tightening. The tightening process is semi-automatic or fully manual, requiring manual participation. Not only labor intensity is big, work efficiency is low, and has certain danger. There is no automatic tightening equipment in the field of production and assembly of shells and small-caliber missiles in China, and the current operation method cannot meet the requirements of auto...
