Description

Technical Field

[0001] The utility model relates to the technical field of fixing fixtures, in particular to a fixing fixture for automobile parts. Background Art

[0002] As the foundation of the automobile industry, auto parts are a necessary factor to support the sustainable and healthy development of the automobile industry. In particular, the current independent development and innovation in the automobile industry, which is in full swing, requires a strong parts system to support it. The independent brand and technological innovation of the whole vehicle need parts as the basis, and the independent innovation of parts has a strong driving force for the development of the whole vehicle industry. They influence and interact with each other. Without the independent brand of the whole vehicle, the R&D and innovation capabilities of the strong parts system are difficult to burst out. Without the support of a strong parts system, it will be difficult for the independent brand to grow bigger and stronger. Automotive fixtures play a very important role in the installation process of parts, especially in the positioning, welding and assembly processes of parts.

[0003] However, the existing automobile parts fixing fixtures have some defects or shortcomings:

[0004] Since some automobile parts are generally of special-shaped structures, when welding some accessories to the upper end of the parts, the angle of the parts cannot be adjusted, and the operator can only rely on changing the angle of the handheld welding gun to weld them. Due to too many clamping mechanisms on the fixture and the distortion of the welding gun angle, welding interference will occur, making it impossible to weld some welding parts in place, or because the welding gun and the horizontal plane cannot ensure a vertical angle, it will cause the problem of weld distortion, thereby affecting the welding quality of automobile parts; and the fixed parts are not easy to adjust in height. When the staff performs welding operations, they need to bend over or squat for a long time to weld, which is more laborious and less practical. Utility Model Content

The clamping mechanism 5 can be composed of a bracket, a vertical plate, a support block, a hand clamp, a pressure arm and a pressure block. By operating the hand clamp, the pressure arm is controlled to drive the pressure block to move, and then the parts placed on the support block can be clamped. The use of several clamping mechanisms 5 can effectively clamp and fix the parts. When the staff needs to process and weld the peripheral automobile parts, the parts are placed on the supporting assembly 6. The supporting assembly 6 is convenient for adjusting the height of the parts before and after the parts are fixed by the clamping mechanism 5, so as to facilitate the material taking and placing before and after the automobile parts are fixed, and the clamping mechanism 5 does not cause contact wear to the automobile parts during the material taking and placing process; and after the automobile parts are stably fixed and positioned by several clamping mechanisms 5, the height of the fixing table 4 can be controlled by the provided lifting assembly 2, so that the automobile parts on the fixing table 4 can be adjusted in height to adapt to the rise of the staff, so that the staff can adjust the height of the parts when the parts are fixed. When performing processing and welding operations, there is no need to bend over or squat for a long time, which saves time and effort and reduces the labor intensity of the staff. When the position of a part is not convenient for welding due to angle problems, the lifting component 2 can be used to control the fixing table 4 to be lifted to the maximum height, and then the angle of the fixing table 4 is adjusted by the set adjustment component 3, and the stable positioning is completed after the angle adjustment, so that the automobile parts are adjusted to an angle that is convenient for processing and welding. At this time, it is convenient for the staff to perform processing and welding operations on some angles of the automobile parts to avoid that some positions of the automobile parts cannot be welded in place when the automobile parts are placed horizontally, affecting the welding quality; and through the set lifting component 2, it is convenient to control the fixing table 4 to move down to the extreme position when in use, at which time several moving wheels 8 are in contact with the ground, and the base 1 is freed from the conflict with the ground.
