Description
Technical Field
[0001] This utility model relates to the field of bolt tapping technology, and in particular to a tapping device for bolt processing. Background Technology
[0002] The emergence of tapping equipment for bolt processing is an inevitable result of the increasing demand for large-scale bolt production and processing precision. In fields such as machinery manufacturing, construction, and automobiles, bolts are core connecting components, and the processing quality of their threaded holes directly affects the stability of the connection. Early manual tapping or processing with simple tools had problems such as extremely low efficiency (long processing time per workpiece), poor precision (uneven thread depth, irregular tooth profile), and insufficient consistency (large human operation errors). Moreover, long-term manual operation easily leads to worker fatigue, further reducing processing quality. As industrial production has increased its requirements for bolt specification diversity (such as different diameters and pitches), processing efficiency, and standardization, traditional methods are difficult to adapt. At the same time, the high requirements of bolt application scenarios for threaded connection strength (such as anti-loosening and wear resistance) have driven the development of specialized tapping equipment with integrated automated feeding, precise speed control, and multi-specification adaptation functions. This type of equipment replaces manual operation with mechanical structure, which not only improves tapping efficiency and precision but also reduces labor costs, becoming a key piece of equipment in the bolt processing process to ensure product quality and meet the needs of large-scale production.
[0003] However, due to the varying sizes, thicknesses, and lengths of existing bolts, and the fact that traditional equipment is mostly designed with fixed specifications, when encountering bolts of different sizes, it is necessary to disassemble and replace core components such as tapping tools, chucks, and guide sleeves when changing the bolt diameter and pitch. In some cases, the feed track spacing also needs to be adjusted. Each switch often takes more than 30 minutes, which seriously affects the continuity of mass production and reduces the efficiency of bolt tapping to a certain extent.
[0004] Therefore, we provide a tapping device for bolt processing to solve the above problems. Utility Model Content
