Description

обжимаетс кулачками, траверса 32 опускаетс и подводит болт 10 к собираемому из- депию. Пружины 2 создают осевое усилие, а привод 5 - торированный момент, которые необходимы дл ввертывани болта 10. Поддерживающа цанга 11 после касани с собираемым изделием утапливаетс внутрь наконечника 6. так как он подпружинен, а кулачки 1 цанги 11 расход тс . По окончании сборки привод 7 смещает наконечник 6 относительно шпиндел 4, между конусами 13 и 15 восстанавливаетс зазор и головка болта 10 освобождаетс . С отводом траверсы 2 от собранного издели кулачки 16 упругого элемента принимают исходное положение, т.е. сход тс , предотвраща проскакивание следующего по ходу болта, при этом подпружиненна цанга 11 также смещаетс в исходное положение (фиг.1). Этим завершаетс полный цикл сборки и начинаетс следующий.crimped by cams, yoke 32 lowers and leads bolt 10 to the assembly of the depot. The springs 2 create an axial force, and the actuator 5 causes a torque that is necessary for screwing in the bolt 10. The support collet 11, after touching the assembled product, is sunk into the tip 6. since it is spring-loaded and the cams 1 of the collet 11 are consumed. At the end of the assembly, the actuator 7 moves the tip 6 relative to the spindle 4, the gap between the cones 13 and 15 is restored and the head of the bolt 10 is released. With the removal of the traverse 2 from the assembled product, the cams 16 of the elastic element take the initial position, i.e. converge, preventing the next bolt from slipping, while the spring-loaded collet 11 also shifts to its initial position (Fig. 1). This completes the full build cycle and starts the next one.

Claims

Claims An apparatus for screwing in bolts comprising a movable body mounted on the yoke with a spindle housed therein and driven to grow, is characterized in that, in order to increase reliability, it is provided with a clamp bar coaxially in the spindle, a guide bush and supporting collet, while the pressure collet is spring-loaded relative to the spindle and has the ability to interact with it by the corresponding conical surfaces made on the inner surface of the spindle and externally the clamping collet surface, and the supporting collet is spring-loaded relative to the guide sleeve, in addition, the clamping collet and the guide sleeve are mounted in the spindle with the possibility of joint axial movement by means of additionally inserted

drive, and the clamping and supporting cams are located at equal levels and alternately.
