July 27, at 2: The dimensions of datum surface are decided by selecting a necessary cross- section from the part drawing. July 26, at The surface of base should be flat smooth and the base should be rigid enough for easy welding and machining. Fixture unit to hold the body parts securely and composed of following item: Sign up for Updates, Education, and More! Skip to main content. Share cla,ping with me and I will include them in a future lesson.

11 Ideas for Clamping Product Parts in Weld Fixtures

A similar question came up and I posted it fxture linked in. The welded block on the end of the clamp arm can help you go around the corner …. Enter the email address you signed up with and we’ll email you a reset link.

Locating pins are available in numerous shapes and sizes in a design. Attend a trade show, do a google search, talk to other machine designers, tour factories.

It wolud be appriciated if you show how to calculate the force required to clamp the object for welding. It also allows you to shorten or lengthen the swing arm. Tixture, designing a fixture in this plane is often a complex process, considering the variations in coordinate systems and basic rules such as maintaining few elements in specific orientations.


I am not an expert on welding. Contact Us Rentapen W.

Designing a welding fixture is based on the location layout. With automated clamps you need to keep the operators fingers out of the way, so put in two-handed controls. A clamp can be defined as a device for providing an invariant location with respect to an external loading system. The forces exerted by the clamps hold a panel securely in the xesign against all fixtrue external forces. When a welding process is producing a load or moment on the body part, it is necessary that a sufficient clamping force must be exerted to withstand such actions.

One of the pins clxmping round, and another one is diamond shaped. Location layout is the selection of the positions and numbers of locators and clamps for assembly of fixture components into a final configuration on a fixture base. The shape of locating surface is a form of cross-section of panel.

I shares some comments in a blog. This manually operated Toggle Clamp has a plate welded below the arm.

BIW Fixture Design

Here holding the yellow product part. I am sure, once you start your brain thinking and creating, you will have some ideas too. Some of it has to be addressed by the welder through technique and process. The clamp also has shims under it. Or, by attaching it to some sort of fixturr or slide.

And here holding the orange part. Sometimes, you have to clampijg creative. In other words a clamp is a force-actuating mechanism of a fixture unit. Butler, Wisconsin USA ph: Rentapen usually makes the fingers out of A2 and heat treats them.


If you are going to be a good designer of weld fixtures and part-holding jigs you must become familiar with clamps and how to use them and modify them. There were several suggestions, like weld both sides at one time, tack weld it first, heat sinks, etc. Think of your finger coming down and holding the part in place but keeping out of the way of the weld gun. Locating surface is configured to receive panel for setting in a correct position and locating a body part from any surface such as flat, curved, or have an irregular contour.

Allowing the clamp to sit lower in the fixture, keeping it within the space parameter requirements for the weld fixture. We often use straight cylinders for clamping. Another bie of the two-part clamp weldment. There is deformation of body assembly due to the welding process effect and resulting variation due to part dimensional variation, when you are designing a fixture you should eliminate them and another objective is achieving body quality within the required tolerances, so you can achieve this purpose by planning location layout.

The tapped hole in the block that is welded onto the claamping allows for the use of a simple hex bolt and jam nut for clamping.
