Forming method, welding jig and welding inspection tool for long shaft and gear plate welding type transmission assembly

Abstract

The invention relates to a forming method, a welding clamp and a welding detecting tool for a long shaft and tooth plate welding type transmission assembly. Tooth plates are subjected to finish punching, welding auxiliary holes are machined and welded in the large tooth plates, and a long shaft is subjected to numerical control machining, is natural and has actual effects. The welding clamp is positioned through the cylindrical face of the long shaft, the end faces of the tooth plates, the welding auxiliary holes of the large tooth plates and teeth of the small tooth plates. The welding detecting tool is firstly used for ensuring the straightness of the long shaft through a V-shaped fixing block and positioning the teeth of one small tooth plate through a detecting tool tooth profile positioning block, then the long shaft is pressed through the welding detecting tool, and finally, the welding detecting tool can detect the tooth profile and the location degree of the rest of the small tooth plates and the tooth profile and the location degree of the large tooth plates through a detection part which can axially move along the long shaft. The method is small in machining error, high in precision, high in positioning precision and capable of conveniently conducting detection, the welding clamp is high in precision and low in cost, and the welding detecting tool is easy to operate and high in efficiency.

Description

technical field [0001] The invention belongs to the field of mechanical processing, and in particular relates to a forming method, a welding jig and a welding inspection tool for a long axis and tooth plate welded transmission assembly. Background technique [0002] Transmission components are an important part of almost all mechanical structures. Ordinary transmission components are relatively simple to manufacture, but for transmission components with complex structures and high requirements for dimensional accuracy and position accuracy, the forming method is more complicated. For example, long shaft The transmission assembly welded with the tooth plate, this transmission assembly is composed of a long shaft and several tooth plates (the tooth plate is provided with a central hole that matches the long shaft and several teeth, generally there are large tooth plates and small tooth plates ), in addition to the precision requirements of the long axis and the tooth plate its...

[0002] Transmission components are an important part of almost all mechanical structures. Ordinary transmission components are relatively simple to manufacture, but for transmission components with complex structures and high requirements for dimensional accuracy and position accuracy, the forming method is more complicated. For example, long shaft The transmission assembly welded with the tooth plate, this transmission assembly is composed of a long shaft and several tooth plates (the tooth plate is provided with a central hole that matches the long shaft and several teeth, generally there are large tooth plates and small tooth plates ), in addition to the precision requirements of the long axis and the tooth plate itself, there are precision requirements between the long axis and the tooth plate and between the tooth plate and the tooth plate, but the current long shaft parts, turning is still the main processing method , due to the existence of cutting stress, the parts will be deformed and the precision is low, and how to weld the long axis and the gear plate after forming is also a difficult problem. The traditional manual welding process, the product quality is greatly affected by human factors, and the precision is not high. , the quality consistency is poor, and how to check the accuracy after welding is also a problem. At present, the coordinate measurement accuracy of the precision-level three-coordinate measuring machine can reach the micron level, and the spatial size can be measured, but it is not suitable for batch rapid inspection in the manufacturing industry. less efficient
