Problems solved by technology
[0004] 1. When using a vibrating plate to feed nuts, only regular nuts are applicable, and separated nuts cannot be used for feeding, and when using a vibrating plate for feeding, because there will be bumps and friction between the nuts and between the nuts and the vibrating plate. Suitable for coated split nuts;
[0005] 2. There is no floating mechanism at the end of the robot, and when the nut is tightened, the thread of the nut will be damaged;
[0006] 3. When assembling and tightening different types of nuts, there is no quick change device, which takes a long time and is not easy to replace when changing the type

The invention provides automatic equipment for assembling and tightening a separated nut assembly, which comprises a platform, and a loading tray device, a tightening device, a loading and unloading robot, an upper protective cover and a fixing tool which are arranged above the platform, and the loading tray device, the tightening device, the loading and unloading robot and the fixing tool are all positioned in the upper protective cover; a tightening device, a feeding and discharging robot and a fixing tool are arranged on one side of the feeding tray device. According to the automatic equipment for separating nut assembly assembling and tightening, a nut body and a base body are separated, feeding and discharging are achieved through the feeding and discharging robot, and the assembling efficiency and the assembling precision are effectively improved; the floating clamping mechanism is adopted to clamp the base body, the double floating sliding tables enable the base body to have two degrees of freedom, meanwhile, during pre-tightening, the longitudinal moving air cylinder is in floating control, the base body has the up-down floating degree of freedom, pre-tightening of the separation nut body and the base body is in flexible assembly, threads are effectively prevented from being damaged during pre-assembling, and the assembling and tightening quality is improved.
Description
technical field [0001] The invention belongs to the field of aerospace separation nut assembly and tightening, in particular to an automatic device for assembly and tightening of a separation nut assembly. Background technique [0002] The separation nut is mainly used in the aerospace field. It consists of a separation nut body and a base body. Refer to the instructions attached Figure 9 , where a refers to the separation nut body, and b refers to the base body. The base body is connected with the separation nut body through threads to form a separation nut. During the assembly and tightening process of the separation nut, it is mainly carried out manually. Then use a special torque wrench or electric wrench for tightening. Usually, the number of nuts to be tightened is large and the torque requirement is large. The assembly and tightening process is time-consuming and labor-intensive, and the efficiency is low. Some automatic tightening equipment is easy to damage the thr...
