Elements of Jigs and Fixtures. Various elements of jigs and fixtures and their details are follows. It may be heat treated to relief the stresses.

In this post. And also you can download the PDF file of this post. 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.

A Theoretic Study on Cam-Clamping Device

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.

The cam-clamping device discussesed in this article involves replaceing the eccentric circle with a cam, as shown in Fig. The cam profile curve can be designed according to any requirements.

The advantages of this replacement are obvious, in addition to preserving the advantages of the circular eccentric fixture, the cam-clamping can be designed according to the actual needs of clamping paths and selection of the appropriate cam profile to improve the self-locking.

Tool Design-3607 Locating Clamping Jigs Completed

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 this article we will discuss about:- 1. Meaning of Clamping Device 2. Basic Rules of Clamping Device 3.

Locating n Clamping Devices in Jigs and Fixture

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. A Fixture is a special workholding device that holds work during machining or assembly operations and establishes size dimensions General purpose clamps and chucks are not fixtures or jigs.

 Давайте же, - скомандовал Фонтейн. Джабба нажал на клавишу. И в следующую секунду все присутствующие поняли, что это было ошибкой. ГЛАВА 119 - Червь набирает скорость! - крикнула Соши, склонившаяся у монитора в задней части комнаты.  - Неверный ключ.

 - Что ты сказала. Чем ты занята.
