Novel high-efficiency cross symmetric servo feed variable-frequency driving bar grooving machine

Abstract

The invention relates to a novel high-efficiency cross symmetric servo feed variable-frequency driving bar grooving machine, which belongs to the machine manufacturing field, and overcomes the shortcomings of low grooving efficiency, inaccurate grooving position and the like of a traditional grooving machine. Equally spaced V-shaped grooves are rotatably turned on a bar by symmetric cross turning tools, four turning tool fixing beams are crossly and symmetrically arranged in the circumferential direction, and 5-80 equally spaced turning tools can be mounted on each fixing beam. An alternating-current servo motor can be used for leading the turning tool fixing beams to radially advance and retreat in optional regularity by the aid of three movable small disks and an oblique mechanism. An alternating-current variable-frequency motor is used for driving and rotating the fixing beams and dozens of turning tools to simultaneously, radially and symmetrically groove a static bar positioned at a center by the aid of tool rest guide posts on four fixed large disks, and 20-320 grooves can be turned at one step. The grooving machine has the advantages of high grooving efficiency, simple structure, fine reliability, operational safety, high grooving precision and the like.

Description

1. Technical field [0001] The invention belongs to the technical field of near-net and high-efficiency precision forming in mechanical manufacturing. Adopting the way that the bar does not move and the turning tool rotates to make equal-spaced V-shaped grooves, the AC servo motor can obtain any regular knife advance and retreat control, and the AC frequency conversion motor can drive the rotary fixed beam and dozens of tools at any settable speed. At the same time, the turning tool notches radially symmetrically on the stationary bar. 2. Background technology [0002] In the industrial field, it is often necessary to slot the bar or pipe or cut the pipe. Some commonly used accessories such as the connecting pin used on the motorcycle chain, the roller in the rolling bearing, the tiny motor shaft used in a large number of toys, etc. Production also requires a cutting process. At present, these slotting or cutting actions are usually realized by refitting old-fashioned lathe...

AI Technical Summary

Problems solved by technology

At present, these slotting or cutting actions are usually realized by refitting old-fashioned lathes, and these equipments are generally relatively low in automation and efficiency; more importantly, the turning tool does not rotate while the bar or pipe rotates during lathe processing. , if the length of the bar or pipe is more than 4-7 meters, the high-speed rotating part exposed to the slotting machine will generate centrifugal force due to axial bending, causing vibration and noise and causing energy loss
