New energy automobile rear axle welding equipment

Abstract

The invention discloses new energy automobile rear axle welding equipment which comprises a control base, a servo deflection seat, a feeding sliding seat and a flexible clamping assembly, the servo deflection seat is rotationally installed on the top face of the control base, and the flexible clamping assembly is fixedly installed on the surface of the feeding sliding seat and fixed to the output end of the servo deflection seat through the feeding sliding seat. The input ends of the control base, the servo deflection base, the feeding sliding base and the flexible clamping assembly are electrically connected with a controller, and the input end of the flexible clamping assembly communicates with a pneumatic driving assembly. According to the automobile rear axle assembling and clamping device, a multi-shaft servo driving platform structure is adopted, assembling and clamping of an automobile rear axle are achieved through the control base, the servo deflection base and the feeding sliding base, and programming driving is conducted under servo control; the assembly position and any angle of a rear axle workpiece are automatically adjusted, so that workers can conveniently conduct welding assembly operation, the device is suitable for work of a mechanical arm automatic welding machine, automatic transformation is completed, and the rear axle assembly precision and the work efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a rear axle welding equipment of a new energy automobile. Background technique [0002] The rear axle of the car refers to the component of the rear drive shaft of the power transmission of the car. It consists of two half-bridges that allow differential motion of the half-axles. At the same time, it is also a device used to support the wheels and connect the rear wheels. If it is a vehicle driven by the front axle, then the rear axle is just a follow-up axle, which only plays a bearing role. If the front axle is not a drive axle, then the rear axle is a drive axle. At this time, in addition to the bearing role, it also plays the role of driving and deceleration and differential speed. [0003] The three-section assembled light axle housing for the rear drive axle of an automobile includes the axle housing tube, the upper body of the axle housing, the lower bo...

Problems solved by technology

[0004] The existing welding of tooling mainly adopts hydraulic lifting frame or gantry crane to support or lift the rear axle and perform manual welding operation. Because it is completely manual operation, it requires high assembly skills for the operator, which is not only labor-intensive , and the consistency of the assembly position of the opening bushing cannot be guaranteed, which may lead to poor quality of the rear axle housing ring seam, and even affect the safe driving performance of the vehicle, and the way of hydraulic lifting frame or gantry crane makes the weight distribution of the rear axle in a certain position. One point is easy to cause damage to the surface of the workpiece, and the angle adjustment is inconvenient

The quality of the welding seam of the automobile rear axle housing is controlled as a key characteristic. Once a quality problem occurs, the rear axle housing of the automobile may be broken. In the lightest case, the chassis of the automobile will lose power and cannot drive, and in severe cases, it may easily cause serious traffic accidents.

[0005] In view of this, the existing problems are studied and improved, and a welding equipment for the rear axle of new energy vehicles is provided to solve the existing problems of difficult welding operations and the inability to accurately calibrate the position of the tooling. Through this technology, To achieve the purpose of solving problems and improving practical value
