Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of roller welding positioning device, belong to the technical field of agricultural machinery assembly. BACKGROUND

[0002] In the wheat machine, the roller is responsible for the transmission and output of threshed material during the operation of the wheat machine. If the dynamic balance performance of the high-speed rotating roller is poor, it will cause unbalance failure, and further cause the machine body to vibrate. For the roller that produces a larger vibration during production operation, only the replacement by disassembly can achieve the effect of reducing vibration, which in turn increases the maintenance cost of the equipment. Therefore, in order to reduce the original unbalance of the roller, avoid vibration during subsequent machine operation, and even the vibration far exceeds the standard value, the dynamic balance must be strictly controlled during the production process of the roller. In the existing roller welding, the laser scribing is used when the roller barrel is discharged. After welding the barrel, the baffle position is determined by laser scribing on the barrel, and then the blade is welded. Since the baffle is directly in contact with the barrel for welding, it is impossible to ensure that the distance from the welding position of each blade to the center of the barrel is consistent, resulting in poor dynamic balance. In addition, since the width disc is placed on the inside of the barrel, the positioning of the middle shaft and the width disc of the roller requires a set of separate welding fixture for positioning, which increases the cost and equipment occupation area.

The width plate positioning mechanism 300 is arranged below the product part position. The extension and retraction of the width plate end face positioning plate 302 is controlled by the first positioning cylinder 301, thereby improving the space utilization and ensuring that the width plate end face positioning plate 302 does not interfere with the drum during subsequent drum assembly.
