Description

Изобретение относится к машиностроению и может быть использовано в устройствах бесступенчатого закрепления деталей на валу или штанге в любом требуемом положении.The invention relates to mechanical engineering and can be used in devices for continuously fixing parts on a shaft or rod in any desired position.

Известно устройство для осевой фиксации детали на валу, содержащее шарик, установленный в отверстие детали и в лунке вала [1).A device is known for axial fixing of a part on a shaft, containing a ball installed in the hole of the part and in the shaft hole [1).

Недостатки известного устройства состоят в невозможности фиксировать детали в любом месте вала или штанги значительной длины и необходимости наносить на них лунки.The disadvantages of the known device are the inability to fix parts anywhere on the shaft or rod of considerable length and the need to put holes on them.

Известен также фиксатор для закрепления детали в любом месте вала или штанги любой длины, содержащий фиксирующий элемент, выполненный в виде цангового зажима, взаимо- , действующего с зажимной гайкой [2].Also known is a latch for securing a part anywhere on a shaft or rod of any length, comprising a latching element made in the form of a collet clamp interconnected with a clamping nut [2].

Данное устройство по своей технической сущности и достигаемому результату является наиболее близким к предлагаемому изобретению.This device in its technical essence and the achieved result is the closest to the proposed invention.

Цель изобретения — повысить нагрузочную способность и снизить технологические точности и стоимость изготовления.The purpose of the invention is to increase the load capacity and reduce technological accuracy and manufacturing cost.

Это достигается тем, что фиксирующий элемент выполнен в виде пружины кручения, охва2 тывающей вал, а деталь и гайка - с отверстиями для закрепления в них концов пружины.This is achieved by the fact that the fixing element is made in the form of a torsion spring covering the shaft, and the part and nut with holes for fixing the ends of the spring in them.

На фиг. I представлен предлагаемый фиксатор, продольный разрез; на фиг. 2 - сечение А-А (при незафиксированном) положении детали на штанге) на фиг. 1.In FIG. I presents the proposed retainer, a longitudinal section; in FIG. 2 - section AA (with a non-fixed) position of the part on the rod) in FIG. 1.

Фиксатор содержит пружину 1, одним концом установленную в отверстие 2 детали 3, фиксируемой на штанге 4, а вторым — в отверстие 5 зажимной гайки 6. Чтобы исключить самопроизвольное вывинчивание гайки 6, в ступице установлено пружинное кольцо 7.The latch contains a spring 1, one end installed in the hole 2 of the part 3, fixed on the rod 4, and the other in the hole 5 of the clamping nut 6. In order to prevent spontaneous unscrewing of the nut 6, a spring ring 7 is installed in the hub.

Гайка 6 имеет отверстия 8 для ι установки в них инструмента (не показан) при ее соответствующей установке.The nut 6 has holes 8 for mounting a tool (not shown) in them when it is properly installed.

Фиксатор работает следующим образом.The latch works as follows.

Гайку 6 вывинчивают до упора в пружинное кольцо 7, деталь 3 устанавливают на нужном месте штанги 4, после чего гайку ввинчивают до обжатия штанги 4 пружиной 1 с необходимым усилием.The nut 6 is unscrewed completely into the spring ring 7, the part 3 is installed in the right place of the rod 4, after which the nut is screwed until the rod 4 is crimped by the spring 1 with the necessary force.

Предложенное устройство значительно повышает нагрузочную способность, снижает технологическую точность и стоимость его изготовления.The proposed device significantly increases the load capacity, reduces technological accuracy and the cost of its manufacture.

Claims

The invention relates to mechanical engineering and can be used in devices for the stepless fixing of parts on a shaft or rod in any desired position. A device for axial fixing of a part on a shaft is known, which contains a ball mounted in the hole of the part and in the shaft hole 1. The disadvantages of the known device are the impossibility of fixing parts in any place of the shaft of the rod of considerable length and the need to put holes on them. Also known is a retainer for locking the part in any place of a shaft or rod of any length, containing a locking element, made in the form of a collet clamp, interacting with a clamping nut.

2. This device, by its technical essence and the achieved result, is closest to the proposed invention. The purpose of the invention is to increase the load capacity and reduce the technological accuracy and cost of production. This is achieved by the fact that the locking element is made in the form of a torsion spring enclosing the shaft, and the part and the nut are provided with holes for securing the spring ends therein. FIG. 1 shows the proposed retainer, longitudinal section; in fig. 2 is a section A-A (with an unlocked) position of the part on the rod) in FIG. 1. The retainer contains a spring I, one end mounted in the hole 2 of the part 3, fixed on the rod 4, and the second - in the hole 5 of the clamping nut 6. To exclude self-splicing of the nut 6, the spring ring 7 is in place of the nut 7. The nut 6 has holes 8 for i installation tool in them (not shown) with its appropriate installation. The latch works as follows. The nut 6 is screwed all the way into the spring ring 7, the part 3 is installed at the right place by the rod 4, after which the nut is screwed in until the rod 4 is crimped with the spring t with the necessary force. The proposed device significantly increases the load capacity, reduces the technological accuracy and stonness of its manufacture.
