Technical Field
[0001] This utility model relates to a mechanical product assembly equipment, and more particularly to a horizontal rotary worktable for tube assembly. Background Technology
[0002] In the assembly and production of tubular products, various sizes of cylindrical and conical products are often involved. These products differ not only in diameter but also in length. One of the key requirements of the assembly operation is to ensure that the centerline of the product is parallel to the ground, which places specific adaptation requirements on the specialized equipment used to mount the products. Currently, traditional pipe installation equipment often suffers from poor versatility. Most equipment is designed for pipe products of specific diameters and lengths. When dealing with products of different specifications, it is necessary to change the corresponding tooling fixtures or even the entire equipment. This not only increases the investment cost of fixed assets, but also prolongs production preparation time and reduces production efficiency due to frequent changes in equipment or tooling. Furthermore, with the expansion of production scale and the increase in product variety, the number of specialized equipment required to be placed in the factory also increases, resulting in a large amount of factory space being occupied and low space utilization. Under such circumstances, manufacturing enterprises urgently need a specialized equipment that can adapt to the installation requirements of cylindrical and conical products of different diameters and lengths, in order to reduce equipment investment, improve the versatility of specialized machines on the production line, optimize factory space utilization, and thus improve overall production efficiency while ensuring assembly accuracy.
