Plate spring tensioning tool and machining method

Abstract

The invention discloses a plate spring tensioning tool. Two ends of a bottom plate are connected with a shifting plate through tensioning bolts, and a boss is arranged on the shifting plate. Two ends of the bottom plate are provided with bosses through which the tensioning bolts pass. The middle of the bottom plate is also provided with a boss on which a pin hole for assembling is arranged. The bottom plate is also provided with a groove for matching with the boss on the shifting plate. In the plate spring tensioning tool and machining method provided by the invention, a plate spring is tensioned for assembling by utilizing the external force of the tool, and meanwhile, the tool also plays a supporting role in assembling the plate spring to prevent the deformation generated by the self-weight of the plate spring; in order to ensure that a single plate spring is not staggered in the assembling process, 6 mounting holes with the diameter phi of 33, which are matched with a locating pin 9, are technically machined into articulation holes in the plate spring assembling process, the plate spring is located by the locating pin, connected with the tool into a whole through a screw thread, and machined after reaching the preset tensioning force, thereby avoiding errors generated by inconformity caused by deformation of materials and improving the assembling precision.

Description

technical field [0001] The invention relates to the field of leaf spring machining, in particular to a leaf spring tensioning tool and a leaf spring processing method. Background technique [0002] The leaf spring assembly of the leaf spring hydraulic vibration device in the continuous casting machine is as follows image 3 , Figure 4 , Figure 5 , Image 6 , Figure 7 and Figure 8 As shown, a set of leaf spring assembly is composed of two single leaf springs, and the center distance between the positioning pin holes is required to be a negative tolerance, and the center distance between the positioning pins of the leaf spring assembly installed on the frame requires a positive tolerance, so Just make leaf spring assembly be in tension state. For the processing of leaf spring assembly, domestic manufacturing companies often take the following process steps to meet the design requirements: the blank is a cold-rolled plate and the plate thickness requires a positive dev...

AI Technical Summary

Problems solved by technology

Due to hoisting, self-weight and cutting force during processing, etc., the leaf spring will be deformed, and there is no secondary correction process, resulting in the illusion of negative tolerance of the hole distance of the processed leaf spring group, so that it cannot meet the tensioning requirements of the design, so that It will cause uneven force on each leaf spring group in the vibration device and affect the function and life of the vibration device
