Description

Technical Field

[0001] This invention patent belongs to the field of steel leaf spring manufacturing technology, and in particular relates to a device that can simultaneously complete the milling and boring of double-headed coiled ears of leaf springs for new energy vehicles. Background Technology

[0002] Leaf springs are the most critical damping components in the suspension systems of new energy vehicles. Different vehicle models require leaf springs of different specifications. Currently, in the production process of leaf springs, the leaf springs are fixed above the mold, the double lugs of the leaf springs are bored, and the side walls of the double lugs are milled to meet the dimensional requirements. Currently, most leaf springs require fixing the leaf spring above a mold on the boring machine body and using a boring bar to bore the rolled ears during boring. Afterward, the leaf spring needs to be moved back to the milling machine to mill the sidewalls of the rolled ears. If there are two rolled ears, this requires repeated clamping, which increases the number of steps, raises production costs, reduces production efficiency, and cannot guarantee product dimensional consistency. Therefore, developing a device with a simple structure that allows simultaneous boring and milling of double rolled ears of leaf springs while the leaf spring is positioned above the machining machine body is of significant application value. This device effectively improves processing efficiency, reduces processing steps, and saves manpower and resources.

[0003] The purpose of this invention is to provide a device that can simultaneously perform milling and boring of double-headed coiled ears for leaf springs in new energy vehicles. This addresses the problem that most current leaf springs require fixing the leaf spring above a mold on the boring machine body and using a boring bar to bore the coiled ears. Subsequently, the leaf spring needs to be moved back to the milling machine to mill the side wall of the coiled ears.

[0024] When using this invention patent: (e.g.) Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6As shown, firstly, according to the size of the leaf spring and the positions of the boring machine body 4, the first milling machine body 5, and the second milling machine body 6, the setting program needs to be input into the intelligent module. The middle of the leaf spring is placed directly below the clamping cylinder 30, with the left and right ends of the leaf spring passing through the U-shaped grooves of the leaf spring support 32 and positioned directly below the end of the clamping member 33. The clamping cylinder 30 and clamping cylinder 34 are activated, the clamping telescopic rod extends and pushes the middle of the leaf spring downwards, and simultaneously the clamping telescopic rod extends and pushes the top of the clamping member 33 downwards to fix the rolled ear.

According to the position dimensions of the rolled ear at the right end of the leaf spring, the position dimensions of the boring machine body 4 at the right end, and the position dimensions of the first milling machine body 5 and the second milling machine body 6 at the right end, the intelligent control module sets the program, starts the running program, and repeats the above work instructions to complete the boring and milling process of the rolled ear at the right end of the leaf spring. During the operation, the leaf spring only needs to be fixed below the leaf spring fastening seat 3.By moving the leaf spring fastening seat 3 and the leaf spring to the positions of the boring bar 45 and the milling cutter 54, and by moving the boring bar 45 and the milling cutter 54, the ear-rolling boring and milling processes are completed. This eliminates the need to move the leaf spring to different machine bodies to complete different processes. Furthermore, during the milling process, the first milling machine body 5 and the second milling machine body 6 operate simultaneously to complete the milling process, resulting in higher efficiency. In summary, this invention patent has the advantages of simple structure, and during use, the leaf spring is located above the processing machine body, allowing for simultaneous completion of leaf spring double-ear boring and milling processes, effectively improving processing efficiency, reducing processing steps, and saving manpower and resources.
