Description

Technical Field

[0001] The present invention belongs to the technical field of mechanical equipment, and more specifically, relates to a circumferential multi-bolt fixing device and method. Background Art

[0002] Generally, there are several assembly methods for fasteners, such as riveting, welding, bonding, and bolting. Bolt connections have the advantages of simple assembly, convenient disassembly (reversible), high efficiency, low cost, and controllable bolt tension. Therefore, bolt connections are widely used in production and life.

[0003] The connector is fixed by bolts, mostly using welding bolts or welding nuts. When assembling, it is only necessary to assemble the nuts or bolts and tighten them. However, in actual production, due to the small space for parts assembly and other reasons, there are two connectors with through holes, which need to be fixed by bolts and nuts. After the bolts are inserted, one end of the bolt head needs to be fixed with an open-end wrench (to prevent the bolt from rotating), and the other end needs to be tightened with an open-end wrench or an electric tool with a sleeve. The nut; this fixing method can only be fixed by a single bolt one by one, and the open-end wrench needs to be repositioned for each bolt fixed, and the sleeve is used with an electric tool to tighten one by one. If the connector fixing bolts are distributed in a circular or rectangular distribution, multiple fasteners are required for fixing. Whether it is 4 bolts or 8 bolts, they need to be operated multiple times. For the same operation steps, the workload becomes huge and the operation is difficult. Usually, it only takes 1 minute to fix one bolt, so fixing multiple bolts wastes a lot of time, and the production assembly or maintenance efficiency is low. Therefore, it is urgent to provide a fixing device or fixing method that is simple, fast, time-saving, labor-saving, and efficient. Summary of the invention
