Strengthening the Welding and Lifting of Automobile Fixtures in the Body Department

The top priority of automotive fixture management. Through continuous improvement and improvement of automotive fixtures, it is ensured that the structure of automotive fixtures is more reasonable and the accuracy is improved, which can provide an important guarantee for ensuring the overall quality of the car cab.

1、 Conduct training and clarify requirements.

Doing things must have a clear purpose and requirements, so that you won't lose your direction and the results of doing things will be as perfect as possible. Welding employees, through on-site learning and discussion, have identified the rubber sealing strip as the welding fixture. Through the coordination of positioning pins (reference pins), S-shaped blocks (reference planes), clamping arms, and other components on the fixture, the workpiece (stamping or assembly) is installed and clamped at the position set by the process, preventing movement and displacement of the workpiece, ensuring consistency and stability in the welding accuracy of the vehicle body.

2、 Familiar with the structure and understanding the purpose.

Welding fixtures are generally composed of a table, a support, an L-plate, a reference pin, a reference plane, a clamping mechanism (cylinder, clamping arm, U-shaped limit block, etc.), etc. The function of each component is different. In the testing and debugging of professional technical personnel, department employees adhere to the principle of "one look, two questions, and three hands", just like crops that have been experiencing sweet dew after a long drought, eagerly absorbing "nutrients". In the subsequent production, it is like an old cow ruminating, discussing again and applying it to the actual production process.

3、 Grasp characteristics and strictly control accuracy.

The welding fixture should not only meet the welding requirements between processes, but also ensure the overall welding accuracy. Due to the varying sizes and complex shapes of stamping parts, each fixture has its own structure, positioning, and clamping characteristics, which are full of rich particularities. In order to ensure that the special performance of various fixtures can be quickly mastered by employees, the department assigns responsibility for various fixtures to individuals in hardware die-casting plastic molds, fixtures, and fixtures. The production of fixtures is standardized and regularly inspected, so that problems such as loose and worn positioning pins, loose positioning blocks and pressure blocks, and cylinder stroke deviation can be eliminated in a short time, reducing welding accuracy deviation and preventing the occurrence of batch quality accidents.

4、 Reasonably optimize based on reality.

In the practical application of fixtures, the height of operation, the passing ability of welding tongs, and the position of the operator can all have an impact on welding. The department communicates and coordinates with the technical department in terms of production rhythm, welding point allocation, fixture layout, welding sequence, and other aspects according to the principle of "fixture matching production, personnel matching fixture", to carry out reasonable personnel allocation and fixture optimization. Through learning optimization and adjustment, the enthusiasm of employees has been greatly improved, and a series of improvements have emerged, such as optimizing floor sub assembly fixtures and door repair welding fixtures.

In the process of controlling the appearance quality of the car body, the welding fixture of the car body skeleton plays an important role. Xingyongjia Automobile Fixture Body Department has taken various measures to increase the management of fixtures.
