Abstract

Inventia se refera la constructia de masini, in special la elementele de blocare a imbinarilor cu filet. Procedeul de confectionare a imbinarii cu filet consta in confectionarea fara gaura filetata pentru prizon (6) a piulitei (1) si contrapiulitei (2) cu posibilitatea insurubarii contrapiulitei (2) in piulita (1), insurubarea si fixarea lor in mandrina strungului. Dupa aceasta in ele se executa gaura filetata pentru prizon (6). Pe piulita (1) si contrapiulita (2) se executa o canelura comuna (7) pentru indicarea coinciderii filetelor (4 si 5) acestor elemente la asamblarea lor cu prizonul (6)The invention relates to the construction of machines, in particular to the elements for locking the threaded joints. The process of making the thread joint consists in making without the threaded hole for prison (6) the nut (1) and the contrapulitis (2) with the possibility of screwing the contrapulite (2) in the nut (1), screwing and fixing them in the lathe chuck. After that, in them the threaded hole for the prison (6) is executed. On the nut (1) and the nut (2) a common groove (7) is executed to indicate the coincidence of the threads (4 and 5) of these elements when they are assembled with the prison (6)

Description

[0001] Invenţia se referă la construcţia de maşini, în special la elementele de blocare a îmbinărilor cu filet.[0001] The invention relates to machine construction, in particular to locking elements for threaded joints.

[0002] Se cunoaşte îmbinarea cu filet, care conţine piuliţă, contrapiuliţă şi prizon. Contrapiuliţa se înşurubează în piuliţă, filetul prizonului şi fileturile piuliţei şi contrapiuliţei care interacţionează cu filetul prizonului coincid, iar fileturile de îmbinare a lor şi filetul prizonului nu coincid [1].[0002] A threaded joint is known, which comprises a nut, a locknut and a stud. The locknut is screwed into the nut, the stud thread and the threads of the nut and locknut interacting with the stud thread coincide, and the threads of their connection and the stud thread do not coincide [1].

[0003] Se cunoaşte, de asemenea, îmbinarea cu filet, care conţine un prizon înşurubat în piuliţa cu contrapiuliţa. Pasul filetului prizonului este de stânga, iar pasul filetului contrapiuliţei este de dreapta şi coincide cu pasul filetului piuliţei [2].[0003] The threaded connection is also known, which comprises a stud screwed into a nut with a locknut. The thread pitch of the stud is left-handed, and the thread pitch of the locknut is right-handed and coincides with the thread pitch of the nut [2].

[0004] Dezavantajul acestor soluţii constă în faptul că nu este cunoscut modul de confecţionare a filetului interior pe şurub, în piuliţa de bază şi în contrapiuliţă.[0004] The disadvantage of these solutions is that the method of making the internal thread on the screw, in the base nut and in the lock nut is not known.

[0005] Problema pe care o rezolvă invenţia constă în elaborarea unui procedeu de confecţionare a filetului interior, astfel încât canalul filetat al piuliţei şi contrapiuliţei să formeze un tot întreg.[0005] The problem solved by the invention consists in developing a process for making the internal thread, so that the threaded channel of the nut and the locknut form a single whole.

[0006] Procedeul de confecţionare a îmbinării cu filet înlătură dezavantajele menţionate mai sus prin aceea că constă în confecţionarea fără gaură filetată pentru prizon a piuliţei şi contrapiuliţei cu posibilitatea înşurubării contrapiuliţei în piuliţă, înşurubarea şi fixarea lor în mandrina strungului, după care în ele se execută gaura filetată pentru prizon. Pe piuliţă şi contrapiuliţă se execută o canelură comună pentru indicarea coinciderii filetelor acestor elemente la asamblarea lor cu prizonul.[0006] The method of manufacturing the threaded joint eliminates the above-mentioned disadvantages by consisting in manufacturing the nut and the locknut without a threaded hole for the stud with the possibility of screwing the locknut into the nut, screwing and fixing them in the lathe chuck, after which the threaded hole for the stud is made in them. A common groove is made on the nut and the locknut to indicate the coincidence of the threads of these elements when assembling them with the stud.

[0007] Rezultatul invenţiei constă în obţinerea procedeului, care va permite executarea unei găuri filetate pentru prizon în piuliţă şi contrapiuliţă ca un tot întreg, precum şi indicarea coinciderii filetelor la asamblarea piuliţei şi contrapiuliţei cu prizonul.[0007] The result of the invention consists in obtaining the method, which will allow making a threaded hole for the stud in the nut and locknut as a whole, as well as indicating the coincidence of the threads when assembling the nut and locknut with the stud.

[0008] Invenţia se explică prin desenele din fig. 1 şi 2, care reprezintă:[0008] The invention is explained by the drawings in Fig. 1 and 2, which represent:

[0009] - fig.1, piuliţa de bază şi contrapiuliţa în secţiune, fără găurile de filetare;[0009] - fig. 1, the base nut and the lock nut in section, without the thread holes;

[0010] - fig.2, vedere generală a asamblării piuliţei şi contrapiuliţei pe prizon, în secţiune parţială.[0010] - fig. 2, general view of the assembly of the nut and locknut on the stud, in partial section.

[0011] Procedeul de confecţionare a îmbinării cu filet constă în confecţionarea fără gaură filetată pentru prizon 6 a piuliţei 1 şi contrapiuliţei 2 cu posibilitatea înşurubării contrapiuliţei 2 în piuliţa 1, înşurubarea şi fixarea lor în mandrina strungului. După aceasta în ele se execută gaura filetată 3 pentru prizonul 6. Pe piuliţa 1 şi contrapiuliţa 2 se execută o canelură comună 7 pentru indicarea coinciderii filetelor 4 şi 5 acestor elemente la asamblarea lor cu prizonul 6.[0011] The process of manufacturing the threaded joint consists in manufacturing the nut 1 and the locknut 2 without a threaded hole for the stud 6 with the possibility of screwing the locknut 2 into the nut 1, screwing and fixing them in the lathe chuck. After that, the threaded hole 3 for the stud 6 is made in them. A common groove 7 is made on the nut 1 and the locknut 2 to indicate the coincidence of the threads 4 and 5 of these elements when assembling them with the stud 6.

[0012] Invenţia prezintă următoarele avantaje: oferă posibilitatea de a vedea coinciderea filetelor piuliţei şi contrapiuliţei la asamblarea lor cu prizonul.[0012] The invention presents the following advantages: it offers the possibility of seeing the coincidence of the threads of the nut and the locknut when assembling them with the stud.
