Supporting system

Abstract

The invention relates to a support system comprising a base, a plurality of support plates, a link mechanism and a power output mechanism, wherein the link mechanism is connected to the base; the power output mechanism drives the plurality of support plates to move through the link mechanism; and variable spaces are formed among the plurality of variable spaces. The invention has the advantages that the power output mechanism drives the plurality of support plates to move through the link mechanism to realize the synchronous opening and closing of the plurality of support plates and ensure uniform and adjustable pressure between the plurality of support plates and parts; when the parts are put in and taken out, the plurality of support plates are not in contact with surfaces of the parts, and the plurality of support plates are in an open state; and the plurality of support plates are in a closed state when in contact with the parts. The support system can prevent the deformation of the parts, and has simple structure, and is economic and practical.

Description

【Technical field】 [0001] The invention relates to a support system, in particular to a support system for welding a body in white. 【Background technique】 [0002] In the welding and manufacturing process of the automobile body-in-white, resistance welding is generally used, and the two steel plates are spot-welded into a whole. Since the steel plates are melted at the spot welding place, solder joint pits will be left under the action of pressure. For non-exposed solder joints, this trace does not affect the appearance, but for exposed solder joints with surface quality requirements, it needs to be treated. There are two commonly used methods: one is to adjust the welding pressure and current, but it is easy to form a virtual weld, and the quality cannot be guaranteed; the other is to add a fixed support system, such as figure 1 As shown, the copper backing plate 1 uses the spring 2 to stick to the surface of the part 3. When the part 3 is put in and taken out, it will rub ...

Problems solved by technology

There are two commonly used methods: one is to adjust the welding pressure and current, but it is easy to form a virtual weld, and the quality cannot be guaranteed; the other is to add a fixed support system, such as figure 1 As shown, the copper backing plate 1 uses the spring 2 to stick to the surface of the part 3. When the part 3 is put in and taken out, it will rub against the copper backing plate 1, and it is not easy to put in and take it out. In severe cases, the part 3 will be deformed. This is not allowed in body building
