1. What is a fixture:

     The jig is a large class of tools for woodworking, ironwork, fitter, machinery, electric control and other handicrafts, mainly used as a tool to assist in controlling the position or movement (or both). Because Taiwan was ruled by Japan for a long time, it became accustomed to the term "governance".

2. Main uses:

Has been widely used before the industrial era, including mechanical fixtures, woodworking fixtures, welding fixtures, jewelry fixtures, and other fields. Some types of jigs are also called "molds" or "assistances", the main purpose of which is to reproduce a certain part repeatedly and accurately. An obvious example is that when copying a key, the original key is usually fixed to the fixture, so that the machine can copy the new key by guiding the appearance of the original key.

Many fixtures are created because of business needs, because there are many types of fixtures that are customized, and some are designed to increase productivity, repeat specific actions, or make work more precise. Because the design of the fixture is basically based on logic, similar fixtures may be produced separately for different times and places.

Advantages and disadvantages:

的 The advantage of using jigs is that if they are the same product, even if the workers do not have very skilled technology, they can quickly use the jig to produce a large number of good products with fewer defects and low variability. However, for a variety of small-scale production modes, the result of many fixtures, on the contrary, has the disadvantage of increasing production costs.

Differences between fixtures and fixtures:

词 The words "fixture" and "fixture" are often easily confused or even misused because of their close use.

The fixture focuses on work and guidance tools; the fixture focuses on holding the tool in a fixed position. Some devices that have both functions (control and guidance tools) are also called fixtures, but devices that only hold but do not have a guide tool are called "fixtures" rather than "fixtures."

 V. Prospects:

After entering the automation and CNC system machines, more and more fixtures have been designed to be able to be controlled automatically, and their technological content is also getting higher and higher. Designers are required to have not only mechanical knowledge, but also electrical control. knowledge.
