Elastic positioning adjusting device for conical pulley

Abstract

The invention discloses an elastic positioning adjusting device for a conical pulley, which is applied to the technical field of automatic welding. The elastic positioning adjusting device is characterized by consisting of a conical pulley shaft, a conical pulley shaft sleeve, a double row angular contact bearing, a copper bush, a bearing cone cushion, an elastic retainer ring for shafts, a disc spring, a movable shaft, a shaft sleeve gland, an adjusting mounting base, a regulating hand wheel, an elastic retainer ring for holes, fastening screws and limit screws. The elastic positioning adjusting device has the advantage that: the elastic positioning adjusting device realizes that the conical pulley can reliably and stably rotate, has functions of accurate elastic positioning and wide-range position adjustment, has looseness-proof function, has compact and even structure, meets the design requirements for miniaturization and portability of a welding carriage and a track, and improves the positioning precision and walking reliability of the steel pipe automatic welding carriage.

Description

technical field [0001] The invention relates to the technical field of automatic welding equipment, in particular to a welding trolley for an automatic welding machine, and is a positioning adjustment device for a welding trolley for an automatic welding machine. Background technique [0002] During the steel pipe welding construction, the welding trolley of the automatic welding machine walks along the circular track fixed on the steel pipe to realize the automatic welding of the pipe. The welding trolley of existing steel pipe automatic welding machine has 4 grooved wheels, and 4 grooved wheels are stuck on the circular track that steel strip bends into. Among the 4 sheaves, 2 are fixed runners with elastic positioning, and 2 are adjustable runners with rigid positioning. The existing welding trolley has relatively low positioning accuracy and cannot meet the requirements of automatic tracking steel pipe welding, and the existing structure of rigid positioning adjusting w...

AI Technical Summary

Problems solved by technology

The existing welding trolley has relatively low positioning accuracy and cannot meet the requirements of automatic tracking steel pipe welding. The existing rigid positioning adjustment wheel or elastic positioning fixed wheel structure cannot meet the application requirements.

Its shortcomings are: ① It cannot meet the design requirements of miniaturization and lightness of welding trolley and track

The existing adjusting runner is fixed by the runner shaft, and the grooved wheel rotates on the bearing at the shaft end of the runner. If the grooved wheel is directly changed into a cone wheel and installed on the bearing at the shaft end, the large diameter of the cone wheel will increase by about 1 times, forming a flat conical structure at the small shaft end of the big wheel, so that the design size of the welding trolley and the track needs to be increased, resulting in an increase in the weight of the equipment

②Because the existing structure realizes the adjustment and positioning through the thread adjustment method of the rotating shaft, it is a rigid positioning, which adopts a rigid adjustment and positioning method, and the rigid adjustment and positioning affects the reliability of the trolley.

Due to the processing error of the track and the deformation during use, the welding trolley may be stuck and unable to walk
