Process for processing external threads of thin-wall threaded sleeve and threaded sleeve turning clamp used for same

Abstract

The invention discloses a process for processing external threads of a thin-wall threaded sleeve and a threaded sleeve turning clamp used for the same. The process comprises the steps of: performing rough turning, performing finish turning on an internal positioning hole, and processing the external threads of the threaded sleeve by using the threaded sleeve turning clamp. The threaded sleeve turning clamp comprises a central positioning rod, a locking nut, a hold-down gasket, a positioning reference plate and a three-paw locking disc. According to the process and the threaded sleeve turning clamp provided by the invention, (1) a material is utilized effectively and a blank material is greatly saved, (2) the principle of concentrated steps is adopted, the transfer time of a product is reduced and the discard as useless in a product transfer process is also reduced, so that the material is saved and the product processing efficiency is improved, and (3) the requirements on a cutter and an operator are low; and simultaneously, the process is suitable for large batch production, the clamping is reliable and the processing quality is stable.

Description

technical field [0001] The invention relates to a processing technology for the external thread of a thin-walled screw sleeve and a clamp for turning the screw sleeve used therefor, belonging to the technical field of thin-walled parts processing. Background technique [0002] With the continuous development of science, thin-walled parts such as screw inserts are used in all aspects of aerospace. Such as aerospace vehicle parts, missile parts and ship parts, etc.; in real life, it is used for inspection equipment and precision instruments in machining factories. Although such thin-walled parts are widely used, processing is a big problem. It is mainly reflected in the fact that such products are thin-walled parts, some have high precision outer circles, and some have high precision inner holes; some have threaded outer circles, and some have special-shaped shapes. When processing such products, the outer circle and inner hole of the part will be deformed, and the deformati...

Problems solved by technology

[0003] The existing process for processing external threads of thin-walled screw inserts mainly adopts the process of car-number of cars-car-fitter. Although this processing method can meet the product requirements, the processing method is complicated and has too many processing steps. High material waste rate

In the process of counting cars, the requirements for workers' operation skills are high {mainly reflected in the fact that when processing the inner groove, if the inner groove blade is not well ground, it will cause vibration marks in the inner hole, which will affect the use and appearance of the product

At the same time, in the fitter process, when removing the burrs on the cut surface of the inner hole, the operator uses a scraper to remove the burrs. If the strength is not strong enough, the product will be unqualified and the product will be scrapped.

[0004] It can be seen that this processing method cannot meet the requirements of batch processing of products.
