Problems solved by technology
In the process of processing the lock keyway, the housing is generally machined on the machine tool through a fixture. Due to the complex structure and large volume of the casing housing 8, the number of threaded sleeves 9 with the lock key 7 locked is large, The installation locations are scattered, resulting in the complex structure of the required fixtures, requiring various positioning, pressing and indexing devices, and even one set of fixtures cannot meet the requirements of processing all threaded bottom hole lock keyways of the casing, such as figure 1 shown

The invention discloses a manual processing tool for locking key grooves on a housing and a processing method thereof, comprising a punch, a sleeve and a screw rod, the punch and the screw rod are arranged in the sleeve, and the sleeve includes The left and right parts with different pipe diameters, the punch is arranged on the left side of the sleeve, one end is threadedly connected with the screw, and the other end protrudes to the outside of the sleeve, and is arranged on the thread of the casing shell. In the bottom hole, the protruding end of the screw rod is connected with the sleeve through a washer and a nut. The processing tool of the invention has the advantages of simple structure, convenient operation, fast and labor-saving, free from equipment requirements, has great popularization value, and provides reference experience for solving similar problems.
Description
technical field [0001] The invention belongs to the technical field of manual processing of locking key grooves in the bottom holes of threaded sleeves of large casings, and in particular relates to a manual processing tool for locking key grooves of casings and a processing method thereof. Background technique [0002] A threaded sleeve is usually installed on the large casing 8, the purpose of which is to reduce the uneven stress and shock resistance of the thread teeth, improve the fatigue strength of the thread, reduce the wear of the thread, enhance the corrosion resistance, and prolong the life of the screw hole. In order to prevent the threaded wire sleeve from rotating in the threaded bottom hole of the casing shell, a threaded wire sleeve 9 with locking key 7 is used. The threaded sleeve with locking key is a fastener with threads on the inner hole and outer diameter, and four or two latch keys on the outer thread. To install the threaded threaded sleeve with locki...
