Problems solved by technology

[0002] The drive axle of the loader is fixed by eight bolts, and the tightening torque of the bolts is required to be 900N m. When tightening the fixing bolts of the drive axle, the impact type air plate machine is generally used for tightening. Manual assistance is required, the labor intensity is high, the torque consistency is poor, the torque fluctuation is 300-400N·m, and the tightening data information cannot be traced
At present, there is no good automatic tightening equipment for drive axle bolts on the market, and the automatic tightening devices on the market are all tightened with small torque, the workpiece is positioned accurately, and the bolt holes are relatively fixed, which cannot adapt to this working condition

Abstract

The invention discloses a drive axle bolt full-automatic tightening machine, and belongs to the technical field of engineering machinery. Defects that in the prior art, time and labor are wasted and torque consistency is poor when a bolt is manually screwed traditionally are overcome. The main structure comprises a support assembly, a driving module assembly and a tightening set assembly. The driving module assembly is installed on the support assembly, and the tightening set assembly is installed on the driving module assembly. The tightening set assembly comprises a rotary tightening machineassembly, a tightening machine supporting frame, an air cylinder, a supporting column and a tightening machine fixing plate. The rotary tightening machine assembly is installed on the tightening machine supporting frame, the tightening machine supporting frame is installed on the supporting column, and the air cylinder is arranged between the tightening machine fixing plate and the tightening machine supporting frame. The machine is mainly used for tightening a drive axle bolt.

Description

Technical field: [0001] The invention belongs to the technical field of engineering machinery, and in particular relates to a fully automatic tightening machine for drive axle bolts. Background technique: [0002] The drive axle of the loader is fixed by eight bolts, and the tightening torque of the bolts is required to be 900N m. When tightening the fixing bolts of the drive axle, the impact type air plate machine is generally used for tightening. Manual assistance is required, the labor intensity is high, the torque consistency is poor, the torque fluctuation is 300-400N·m, and the tightening data information cannot be traced back. At present, there is no good automatic tightening equipment for drive axle bolts on the market, and the automatic tightening devices on the market are all tightened with small torque, the workpiece is positioned accurately, and the bolt holes are relatively fixed, which cannot adapt to this working condition. Invention content: [0003] The t...
