The invention relates to a left-right side body welding clamp for single-double row vehicle model conversion. The left-right side body welding clamp comprises a work platform. The work platform is provided with a clamp unit. The clamp unit comprises a left vertical plate, a right vertical plate, a left pressing head, a right pressing head, a left air cylinder, a lower air cylinder, a right air cylinder, a support, fixing plates, a rotating shaft and shaft sleeves. A piston rod of the lower air cylinder is connected with the lower end of the left vertical plate, and a cylinder barrel of the lower air cylinder is connected with the right vertical plate. A piston rod of the left air cylinder is connected with the middle portion of the left vertical plate, and a cylinder barrel of the left air cylinder is connected with the upper end of the left vertical plate. A piston rod of the right air cylinder is connected with the middle portion of the right vertical plate, and a cylinder barrel of the right air cylinder is connected with the upper end of the right vertical plate. The left vertical plate is connected with one shaft sleeve through one fixing plate, the right vertical plate is connected with the other shaft sleeve through the other fixing plate, the rotating shaft is sleeved with the two shaft sleeves and supported on the support, and the support is fixed to the work platform. Side bodies of different vehicle models are welded through one set of clamp, the number of the sets of clamps is reduced, and the production efficiency is improved.
Description
technical field [0001] The invention belongs to the field of welding of automobiles and trucks, and in particular relates to a welding fixture for left and right side walls for conversion of single-row and double-row models. Background technique [0002] The single-row and double-row models in the prior art require the manufacture of two types of welding fixtures, which have no versatility and need to increase investment costs. With the advancement of technology, reducing costs and increasing benefits has always been the pursuit of automakers. Products of different models can be produced on the same set of fixtures, which can ensure the production of single-row models at the same time, and can not interfere with the production of double-row models. The conversion of the fixture is flexible, simple and convenient, which is an urgent need to solve in the prior art. technical problem. Contents of the invention [0003] In order to solve the above technical problems, the obje...
