Problems solved by technology

[0002] During the welding operation of the rail vehicle body, there are a large number of welding operations. Due to the working characteristics of manual welding, it is often maintained in a fixed posture for continuous operation, which may cause fatigue in the waist or knees, and even lumbar muscle strain and knee injuries. In other cases, especially in the process of bottom frame and general assembly where there are many flat welding positions, squatting or kneeling welding postures are often used, and the welding length of a single gun is mostly 500-600mm. Faced with a large number of welds, not only Aggravate physical fatigue and directly affect work efficiency and welding quality

Embodiment Construction

[0015] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0016] Such as Figure 1 to Figure 5 As shown, the welding auxiliary device for relieving waist fatigue of the present invention includes: a fixed base 1, a long guide rail 2, a short guide rail 3, a frame plate 4, an adjustable chest support mechanism 5 and two arm adjustable support mechanisms 6; The guide rail 3, the long guide rail 2, and the frame plate 4 are arranged in parallel in sequence along the length direction of the fixed base 1, and the two ends of the three are fixedly connected with the fixed base 1 respectively; the length of the short guide rail 3 can be designed as 0.5m, and the length of the long guide rail The length of 2 can be designed to be 1m, so that the device of the present invention can not only satisfy the maximum welding seam length, but also not occupy too much operating space. The frame plate 4 is a cuboid flat plate structu...

Abstract

A welding auxiliary device for relieving waist fatigue relates to the technical field of rail vehicle body welding auxiliary tooling, which includes a fixed base, a long guide rail, a short guide rail, a frame plate, an adjustable support mechanism for the chest, and two adjustable support mechanisms for arms. The invention can relieve the stress on the waist of the operator, relieve the fatigue of the arms and shoulders, and can also slide freely along with the welding, which is convenient for operation. The invention reduces the labor intensity of the operator, so that the operator can continuously weld for 1.5 hours, and improves the work efficiency by 20%; the invention reduces the reject rate, and the length of the single-pass weld can reach at least 1m, reducing the weld by 10% The joint rate saves welding seam joint grinding consumables such as file heads and thousand blades, and reduces production costs.

Description

technical field [0001] The invention relates to the technical field of rail vehicle body welding auxiliary tooling, in particular to a welding auxiliary device for relieving waist fatigue. Background technique [0002] During the welding operation of the rail vehicle body, there are a large number of welding operations. Due to the working characteristics of manual welding, it is often maintained in a fixed posture for continuous operation, which may cause fatigue in the waist or knees, and even lumbar muscle strain and knee injuries. In other cases, especially in the process of bottom frame and general assembly where there are many flat welding positions, squatting or kneeling welding postures are often used, and the welding length of a single gun is mostly 500-600mm. Faced with a large number of welds, not only It aggravates physical fatigue and directly affects work efficiency and welding quality. Contents of the invention [0003] The object of the present invention is...
