Elements of Jigs and Fixtures.

Jigs and Fixtures are critical to repeated manufacturing to with high degrees of accuracy and precision. Jigs and Fixtures hold one or multiple parts in one or multiple machine centers to provide stability and repeatable alignment of the part.

In this article we will discuss about:- 1. Meaning of Clamping Device 2. Basic Rules of Clamping Device 3. Clamping Device purpose is to hold work in the correct relative position in the fixture and to ensure that the job is not displaced under cutting forces.

Are you looking for the notes on Jigs and Fixture s? Yap, you are landed in the right destination. A jig is a work-holding devic e that holds, supports, and locates the workpiece and guides the one or more tools to perform a specific operation. In other words, this can also be defined as, used for holding the tools and also guiding the cutting tools. Both the jigs and the fixtures are used to reduce the nonproductive time of any mass production process. The jig is used for guiding the cutting tool like a drill bit , and for doing so, jigs have components like a bush, which comes in contact with the cutting tool.

Against this, a capstan and turret lathe can be easily adapted for repetition work on account of the multi-cooling arrangement and use of transverse stop this increases the rate of production. However, every type of object cannot be machined on a capstan or turret lathe and may involve the use of drilling, milling , planning and grinding machines, etc. If such objects are to be produced in identical shapes and sizes on a mass scale, suitable devices have to be used for holding and locating purposes so that the repetition work can be done. These devices are the jigs and fixtures.

A theoretical study has been made on the cam-clamping device. In this article, we consider specifically the calculations of cam geometry, calculations of clamping force and clamping torque, conditions for self-locking, and conditions for contact strength. Machine fixtures are essential in the process of mechanical manufacturing. There are many different types of fixtures, such as manual jig, pneumatic clamps, hydraulic fixtures, electric fixtures, etc. There are also many ways of clamping, such as incline clamp, screw clamp, eccentric circle clamp, hinge clamp [1], among which the eccentric circle clamp finds wide applications, especially in fast-clamping devices. Although the circular eccentric fixture possesses the advantages of simple structure, convenient manufacturing, and low cost, it suffers the drawbacks of small clamping force, short clamping-surface travel distance, and unreliable self-locking mechanism.

Беккеру удалось увернуться в последнее мгновение. Убийца шагнул к. Беккер поднялся над безжизненным телом девушки. Шаги приближались.

 Ужасное уродство, правда. Но не искалеченная рука привлекла внимание Беккера. Он увидел кое-что другое. И повернулся к офицеру. - Вы уверены, что в коробке все его вещи.

 - Сейчас находится в шифровалке. Смотри. Стратмор пришел вчера с самого утра, и с тех пор его лифт не сдвинулся с места.

Беккер потянулся и дернул шнурок вызова водителя. Пора было отсюда вылезать.

Бринкерхофф кивнул и двинулся следом за Мидж. Фонтейн вздохнул и обхватил голову руками. Взгляд его черных глаз стал тяжелым и неподвижным. Возвращение домой оказалось долгим и слишком утомительным. Последний месяц был для Лиланда Фонтейна временем больших ожиданий: в агентстве происходило нечто такое, что могло изменить ход истории, и, как это ни странно директор Фонтейн узнал об этом лишь случайно. Три месяца назад до Фонтейна дошли слухи о том, что от Стратмора уходит жена.

Неужели попал зараженный файл? - подумал.  - Неужели фильтры безопасности что-то пропустили. В целях безопасности каждый файл, загруженный в ТРАНСТЕКСТ, должен был пройти через устройство, именуемое Сквозь строй, - серию мощных межсетевых шлюзов, пакетных фильтров и антивирусных программ, которые проверяли вводимые файлы на предмет компьютерных вирусов и потенциально опасных подпрограмм. Файлы, содержащие программы, незнакомые устройству, немедленно отвергались. Их затем проверяли вручную.
