Multi-connected pneumatic numerical control device for forming cross-shaped through hole kidney-shaped grooves of bolts

Abstract

The invention relates to a multi-connected pneumatic numerical control device for forming cross-shaped through hole kidney-shaped grooves of bolts. The device comprises a closed enclosure, a channel for the bolts to slide in the radial direction is formed in the center of the enclosure, a pneumatic ejector rod is connected in the channel in a sliding manner, a first milling cutter is distributed opposite to the pneumatic ejector rod, and a first cutter return groove corresponding to the first milling cutter is formed in the end surface of the first milling cutter; an upper die assembly is arranged on the upper portion of the enclosure, a lower die assembly is arranged on the lower portion of the enclosure, and the upper die assembly and the lower die assembly are driven by an external air source to clamp the bolts; and three containing grooves used for containing the bolts are formed in the side edge of the upper portion of the enclosure and distributed in sequence, the bottoms of the containing grooves communicate with the channel, three through grooves which are distributed in sequence and used for allowing a second milling cutter to move are formed in the upper die assembly, and three second cutter return grooves are formed in the lower die assembly corresponding to the through grooves. By designing a pneumatic and numerical control structure, slotting on bolt bodies can be fully automatically operated.

Description

technical field [0001] The invention belongs to the technical field of bolt manufacturing, and in particular relates to a multi-connected pneumatic numerical control device for forming a waist groove of a cross through hole of a bolt. Background technique [0002] With the rapid development of my country's national economy, the production technology and requirements for standard parts are getting higher and higher, and the demand for them is also increasing. Among them, bolts are one of the standard parts with a high utilization rate. However, for the slotting on the main body of the bolt, according to the existing processing technology and processing equipment, the processing efficiency and product qualification rate are still relatively low. In view of the increasing demand for bolts in the market, how to quickly and efficiently complete the processing and manufacturing of bolts is an important issue. current problems that need to be resolved. Contents of the invention ...
