Description

Technical Field

[0001] The utility model relates to the technical field of automobile side panel manufacturing, in particular to a follow-up storage platform for automobile side panel spot welding clamps. Background Art

[0002] In modern automobile industrial production, spot welding technology, as an important connection method in automobile manufacturing, is the main form of side panel resistance welding technology and is widely used in the manufacturing process of sub- and assembly parts of the automobile body. According to many spot welding technology application scenarios, mobile spot welding technology is the main technology for completing automobile body welding tasks on the automobile body welding automation production line. It is suitable for welding thin-walled workpieces such as side panels that have large structural dimensions, complex shapes, and are not easy to move. The welding actuator is a spot welding tongs, which can be divided into X-type spot welding tongs and C-type spot welding tongs according to their shapes. The X-type spot welding tongs are used for spot welding horizontal and near-horizontal welds, and the movement trajectory of the electrode is an arc line. The C-type spot welding tongs are used for spot welding vertical and near-vertical welds, and the electrode moves in a straight line. Based on the functional characteristics of these two welding tongs, and in the side panel welding manufacturing process, a storage rack for the spot welding tongs is required to facilitate the robot to switch the spot welding tongs for a long time.

[0003] At present, the spot welding tongs storage rack adopts a "two pins and one leaning surface" fixing method and a horizontal structure to ensure the storage of the spot welding tongs, which can basically complete the production tasks of automobile companies. With the increase in the types of vehicles and models, as well as the upgrading of the switching frequency of production process planning, the spot welding tongs storage rack using the traditional fixing method has obvious disadvantages. Its storage performance has poor durability, there is an abnormal phenomenon of jamming, and the storage function has weak stability and cannot eliminate spatial errors. At the same time, it occupies a large area of ​​the production site. The intelligent recognition of the storage equipment is unstable and the signal cannot be accurately transmitted. There is a safety risk. Therefore, a follow-up storage table for automobile side spot welding tongs is proposed to solve the above problems. Utility Model Content

[0056] Working principle: When the robot switches the spot welding clamp, it drives the matching mechanism 3 to move. When the hanging plate guide pin 305 at the bottom of the spot welding clamp hanging plate 301 enters into the interior of the positioning guide sleeve 2062, and the two cylindrical pins 2061 enter into the interior of the hanging plate guide sleeve 304, the initial placement is completed. As the spot welding clamp continues to descend, the plug-in sensor female head 302 and the plug-in sensor male head 207 are plugged into each other to transmit the signal, and the top of the identification plate 303 is also detected by the proximity sensor 208, and the qualified signal is further transmitted to ensure safety. After the placement is completed, the pneumatic device 405 starts to extract the driving force, so that the first handle 402 and the second handle 404 respectively drive the two cover plates 406 to protect the spot welding clamp;

[0057] The door-type column 101, the bottom plate 102, the installation adjustment plate 103, the first end plate 104, the second end plate 105, and the left and right lower ribs 8 and the reinforcing ribs 9 in the frame mechanism 1 enhance the stability of the support during the placement of the spot welding clamp and reduce the floor space occupied by the spot welding clamp storage equipment.
