Freely station-switchable welding fixture for multiple vehicle types

Abstract

The invention discloses a freely station-switchable welding fixture for multiple vehicle types. The welding fixture comprises a bottom box; support pillars are respectively connected with the four corners of the outer wall of the bottom of the bottom box by means of bolts; the outer wall of one side of the bottom box is connected with a mounting rod by means of a bolt; the outer wall of the top ofthe mounting rod is connected with a rotating bearing by means of a bolt; the mounting rod is connected with a cross beam by means of the rotating bearing; the inner wall of the bottom of the bottombox is connected with a first sliding rail by means of a bolt, a sliding groove of the first sliding rail is internally connected with a sliding block in a sliding way, and the first sliding rail is connected with a storage box by means of the sliding block; a mounting groove is formed in the outer wall of one side of the storage box, and the inner wall of the top of the mounting groove is weldedwith a sleeve. The freely station-switchable welding fixture for the multiple vehicle types can conveniently adjust and switch welding stations, thus meeting the clamping requirements of parts which are of different models and belong to the different vehicle types, and effectively improving the efficiency of a welding work; the storage box is conveniently drawn out by means of a handle, and scrapsfalling into the storage box can be cleaned, so that the practicality of the device is effectively improved.

Description

technical field [0001] The invention relates to the technical field of welding fixtures, in particular to a welding fixture with freely switchable stations for various car models. Background technique [0002] Since the 20th century, the annual output of automobiles in the world has been calculated in thousands, tens of thousands, and then in tens of millions. By 1978, it had reached about 42.49 million vehicles. The automobile industry has become the world's largest manufacturing industry. In the 1980s, 6 of the 20 largest industrial enterprises in the world were automobile manufacturing companies. In 1980, the number of cars in the world was about 335 million, including 265 million cars and 70 million freight cars and passenger cars. The production and use of automobiles involves a wide range of aspects. In the 1970s, there were about 5 million employees in more than 20 largest automobile companies in the world, and about 25 million employees related to automobiles, suc...

Problems solved by technology

In the 1970s, 36% of steel strips, 44% of cold-rolled steel sheets, 43% of lead, 61% of zinc and 62% of synthetic rubber were used in the production and maintenance of automobiles. Welding is performed after clamping with a fixture, but the structure of the welding fixture currently used cannot be adjusted, which affects the efficiency of the welding work and cannot meet the requirements well
