Description

Technical Field

[0001] The utility model relates to the technical field of hardware clamps, in particular to a high-precision adjustable rear enclosure frame assembly positioning device. Background Art

[0002] In the production of medium and large buses, the welding of the frame assembly is an extremely complex and high-precision process. The accuracy of the assembly welding is directly related to the quality of the entire bus shell. Today, in the field of modern production, the professional division of labor is gradually refined. In the customized production model of products, the professional bus frame manufacturers undertake many frame specifications and models with short production cycles. The batch size of each model is not fixed, which makes the welding fixtures frequently replaced and requires high flexibility. The traditional welding method is to use simple iron plates and square tubes as supports on a work platform and weld them on the platform to position and fix the parts to be welded.

[0003] Most of the existing high-precision fixing fixtures for the front door frame assembly are convenient to use, but they ignore the fact that the fixture itself is simply welded from iron plates and square tubes. In case of large-scale production, it is easy to cause deformation of the fixture itself, resulting in a large difference in the sizes of the first and last parts of the product, causing large deviations in the sizes of the welded parts, frequent product rework and customer complaints. In addition, in the face of "casual" production with many frame states, production cycles, and irregular batches of each model, this method has low fixture cost and short replacement time, but the welding accuracy cannot be guaranteed and there is no traceability of the products. For this reason, we propose a high-precision fixing fixture for the rear door frame assembly.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a high-precision adjustable rear enclosure frame assembly positioning device is proposed. Utility Model Content
