Description

Technical Field

[0001] The utility model belongs to the technical field of aerospace parts, and in particular relates to a fixing device for processing bolts of aerospace parts. Background Art

[0002] Aviation bolts are a kind of mechanical fasteners that connect two or more parts. They are usually composed of screws, nuts, washers and other parts. They are widely used in aviation, aerospace, vehicles and other fields. According to their uses and shapes, aviation bolts can be divided into structural bolts, connection bolts, high-temperature bolts, locking bolts and other types. Aviation bolts need to be fixed when in use to facilitate subsequent processing.

[0003] A Chinese patent with application number CN202122676875.1 discloses a fixing device for processing aerospace bolts, including a fixing plate, wherein grooves are symmetrically provided on both sides of the upper surface of the fixing plate, and a plurality of positioning grooves are symmetrically processed on the inner side walls of the grooves on both sides, and the shape and size of the positioning grooves match the shape and size of the aerospace bolt head.

[0004] The above scheme locks the pressure block by fastening screws, so that the pressure block cooperates with the positioning groove to fix the head of the aerospace bolt. However, in actual use, when disassembling and fixing the aerospace bolt, it is necessary to frequently disassemble and assemble the fastening screws, which can easily cause the connection between the fastening screws and the screw holes to loosen, resulting in poor fixing effect. In addition, disassembly and assembly require repeated disassembly and assembly of the fastening screws, which is cumbersome and has low processing efficiency.

[0005] In view of this, the present utility model is proposed. Utility Model Content

By setting the arc groove, the pressure plate drives the pressure rod to move downward, so that the arc block assists in the installation of the aerospace bolt.

[0012] Optionally, two limit rods are fixedly connected to the upper side of the pressing plate, and the limit rods are slidably matched on one side of the mounting shell. The limit rods are provided to limit the lifting and lowering of the pressing plate.

[0013] Optionally, a guide groove is provided on the upper side of the fixed shell, and a guide rod matched with the guide groove is fixedly connected to the lower side of the T-shaped plate.

[0017] By setting a clamping mechanism, when fixing the aerospace bolt, the head of the aerospace bolt can be placed in the trapezoidal groove. Under the action of the hydraulic cylinder, the pressure plate is moved downward to squeeze the T-shaped plate to move. Under the action of the connecting rod, the pressure block slides out of the slide groove, and the trapezoidal groove is used to fix the head of the aerospace bolt to improve the fixing effect of the aerospace bolt. When the processing is completed, the pressure plate is raised under the action of the hydraulic cylinder to cancel the limit of the aerospace bolt, which is convenient for replacing the aerospace bolt and improving the processing efficiency of the equipment.
