Oscillator that can swing in a "u" shape

Abstract

The invention provides a wiggler capable of swinging in the shape of U, which comprises a motor, a clamping mechanism and a driving device, wherein the driving device comprises a first swing gear, a second swing gear, a swing eccentric wheel, a swing ring, a first swing rod, a second swing rod, a third swing rod, a rotating gear, a first linear bearing, a first slide block, a slide block connecting plate, a second linear bearing and a second slide block, wherein the first slide block and the second slide block can be respectively and glidingly arranged on the first linear bearing and the second linear bearing back and forth; the slide block connecting plate is fixed on the first slide block; the second linear bearing is arranged on the upper surface of the slide block connecting plate; and the clamping mechanism is fixed on the second slide block. Therefore, a gun clamping mechanism can swing in the shape of U. When the gun clamping mechanism is used for U-shaped welding and cutting, the mechanism is convenient to operate, the efficiency is higher, and the welding and cutting quality effect is better. Because the motor which rotates in one direction does not rotate clockwise and anticlockwise as the motor of a traditional wiggler, the wiggler capable of swinging in the shape of U is not easy to burn, has a longer service life and is more durable.

Description

【Technical field】 [0001] The invention belongs to the technical field of welding oscillating devices, in particular to a U-shaped oscillating device. 【Background technique】 [0002] At present, there are several types of oscillating devices on the market, such as arc oscillating, left and right oscillating, and front and rear oscillating. A fixture for clamping the welding torch, gouging torch or cutting torch is installed on the rack; while the arc-shaped swing swing device adopts a mechanical structure to swing the welding torch, so that the welding torch swings in an arc shape, and the swing amplitude and swing speed can be adjusted. For example, the models of Shenzhen Ruiling Industrial Co., Ltd. are HIT-30, HIT-32, and HIT-33 oscillators. However, this kind of oscillator that uses the positive and negative rotation of the motor has been working for a long time, and the motor is easy to burn out, and it can only move left and right or back and forth in a straight line, ...

AI Technical Summary

Problems solved by technology

However, this kind of oscillator that uses the positive and negative rotation of the motor has been working for a long time, and the motor is easy to burn out, and it can only move left and right or forward and backward linearly, and it cannot perform a "U"-shaped trajectory like an arc-shaped oscillator. The swing of "U" shape cannot be performed, and the operation is difficult, and the quality of welding and cutting is relatively poor.
