Embodiment

[0053] Such as Figure 4 As shown, in an aerospace product, the connector needs to be installed and fixed inside the cabin through a miniature screw and nut assembly. Such as Image 6 As shown, the inner diameter of the cabin is R70mm, and the space available for assembly operations inside the cabin is very narrow, and it is difficult to complete the assembly operation of the miniature screw and nut assembly without tools.

[0054] In the traditional assembly process, tools such as tweezers and needle-nose pliers are generally used to assist assembly. During assembly, the miniature screw and nut assembly tends to slip off, leaving excess in the product. Due to the special requirements of aerospace products, the excess must be cleaned. Generally, the excess is cleaned by dumping or disassembling a single machine, which increases the difficulty of assembly and wastes assembly time. At the same time, the traditional assembly process is inefficient and difficult to meet the sch...

Abstract

The invention discloses a mini-screw and nut assembly auxiliary assembling tool and an assembling method. The mini-screw and nut assembly auxiliary assembling tool comprises a left pincers part, a right pincers part, a rotating shaft, a right screw rod and a left screw rod, wherein the left pincers part and the right pincers part are connected together through the rotating shaft and rotate around the rotating shaft; the left screw rod is connected to the right pincers part through threads; and the right screw rod is connected to the left pincers part through threads. The assembling method comprises the following steps: closing the handheld ends of the left pincers part and the right pincers part, and rotating the left screw rod and the right screw rod to adjust a relative distance between the left screw rod and the right screw rod to enable the left screw rod and the right screw rod to respectively press against two ends of a screw; opening the handheld ends of the left pincers part and the right pincers part, putting a nut, a spring washer and a flat pad on a cylinder of the right screw rod in sequence in a sleeving manner; and then closing the handheld ends of the left pincers part and the right pincers part to enable the left screw rod and the right screw rod to respectively press against two ends of the screw, moving the flat pad and the spring washer onto the screw in a sleeving manner, screwing a nut on the screw, and pressing the flat pad and the spring washer.

Description

technical field [0001] The invention relates to an auxiliary assembly tool and an assembly method for a miniature screw and nut assembly, and is especially suitable for the auxiliary assembly operation of the miniature screw and nut assembly in a narrow space. Background technique [0002] Miniature screw and nut assemblies are widely used in mechanical and electronic products, and it is very difficult to assemble miniature screw and nut assemblies in a narrow space. The traditional method is to use tools such as tweezers or needle-nose pliers to clamp flat washers and spring washers and put them on the screws, and use tools such as tweezers or needle-nose pliers to clamp the nuts and tighten the nuts on the screws. The above operation has the following problems: [0003] (1) During the process of loosening tools such as tweezers or needle-nose pliers, flat washers, spring washers, and nuts are easy to slip off and leave excess in the product, which affects the performance ...
