The dimension from the panel to the locating pin leading end straight area should be 5 mm. Click here to sign up.

I am sure, once you start your brain thinking and creating, you will have some ideas too. Contact Us Rentapen W. Log In Sign Up. Some of it has to be addressed by dezign welder through technique and process.

But as you delve into designing more fixtures you will soon learn that not all clamps fit all applications. The shape of locating surface is a form of cross-section of panel. It involves numbers of fixture units and due to the complexity and shape of the component geometry, the choice of elements as well as configuration of each unit tends to change from case to case. July 27, at 2: This configuration will allow easier loading of body part.

This also doubles as a method for locating or pinning a detail. In most applications, locating surface devices locate a panel by its external flat surfaces and flat area, such as: Either by adding a button to the end of the rod.

Sign up for Updates, Education, and More! August 7, at 2: When a welding process is producing a load or moment on biiw body part, it is necessary that a sufficient clamping force must be exerted to withstand such actions.

There are two configurations for position of locating pin: The end of each pin has a round or conical shape or is chamfered for the purpose of maintaining workability such as ease of loading and quality such as prevention of damage. In other words a clamp is a force-actuating mechanism of a fixture unit.

BIW WELDING FIXTURE UNIT | S K –

The tapped hole in the block that is welded onto the clamp allows for the use of a simple hex bolt and jam nut for clamping. Load condition and configuration are not uniform, so it is impossible to set a base shape in general. It is used for more than product line, or similar but different product parts.

This clamp, mounted to a RAPid Riserhas a block welded to the top of the swing arm. This is usually done with the datum surfaces that are reference for locating surface. G S JHA says: Notice the rest pads have yellow shim packs under them.

Designing a welding fixture is based on the location layout.

Fixture unit to hold the body parts securely and composed of following item: With automated clamps you need to keep the operators fingers out of the way, so put in two-handed controls. Help Center Find new research papers in: The taper lead angle is large, 60 degrees or less, for small-size body parts and manual operation, but it is frequently between10 and 30 degrees for large-size body parts fixturre are difficult to handle.

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.

11 Ideas for Clamping Product Parts in Weld Fixtures

There were several suggestions, like weld both sides at one time, tack weld it first, heat sinks, etc. One of the pins is round, and another one is diamond shaped.

The surface of base should be flat smooth and the base should be rigid enough for easy welding and machining. It wolud be appriciated if you show how to calculate the force required to clamp the object for welding. The product part rests on the shoulders of the pins.

Attend a trade clwmping, do a google search, talk to other machine designers, tour factories. September 22, at 6: And here holding the orange part. The clamp also has shims under it. Sometimes one clamp can be used to hold parts in a fixture that runs more than one product.

We often use straight cylinders for clamping.
