Description

Technical Field

[0001] The utility model relates to the technical field of bow plate parts processing, in particular to a tooling for batch processing of bow plate parts. Background Art

[0002] As an important component of mechanical structure, bow plate parts play an irreplaceable role in various mechanical equipment with their unique curvature and shape design. They have multiple roles such as load-bearing body, support parts and connecting parts. They can not only build a stable frame structure to provide basic support for the equipment, but also ensure the precise docking and force transmission between the components to ensure the normal operation and function realization of the equipment. On the basis of meeting specific mechanical requirements and enhancing structural stability, the arc surface design often integrates a complex hole system layout with various hole specifications and different arrangements, aiming to achieve precise coordination with other parts and ensure precise positioning and firm fixation during assembly. In view of the direct impact of hole processing accuracy on the assembly accuracy and operating performance of the mechanical system, strict requirements are placed on the processing technology of bow plate parts.

[0003] At present, the efficiency of the traditional hole processing process of bow plate parts is low. The main reasons include that the existing equipment is usually only capable of single-piece clamping operations. In mass production, each time a part's hole processing is completed, a clamping change is required, which seriously hinders the continuity of the production process. Secondly, during the workpiece positioning process, the operator needs to manually adjust and tighten the pressure plate nut to ensure that the pressure plate is effectively pressed against the bow plate to prevent position deviation due to vibration or uneven force during processing, which affects the hole processing quality. This process is time-consuming and laborious, increasing the labor intensity of workers and reducing production efficiency.

[0004] In addition, when using existing technology to process bow plate parts, the machine needs to be stopped for manual loading and unloading of workpieces after each processing. Frequent start and stop of equipment not only prolongs non-production time and reduces effective working time, but also increases equipment wear and energy consumption, indirectly raising operating costs. In addition, workpiece replacement is often accompanied by the replacement or adjustment of cutting tools such as drills, which further increases the frequency and complexity of tool changes, resulting in a decrease in the overall utilization rate of equipment.

[0005] Therefore, single-piece clamping leads to interruption of production rhythm, high labor intensity of manual clamping and positioning, low equipment utilization due to frequent shutdown and tool change, and increased parts processing costs caused by this chain reaction. These problems constitute the technical bottleneck that restricts the efficient and economical production of bow plate parts. Utility Model Content
