Machinery manufacturing process used to fix the processing object, so that possession of the correct location to accept the construction or testing of the device, also known as fixtures. In a broad sense, any process in the process, used to quickly, easily and securely install the workpiece device, can be called fixture. Such as welding fixture, inspection fixture, assembly fixture, machine fixture and so on.Welding Fixture
One of the most common machine tool fixture, often referred to as fixture. When machining the workpiece on the machine tool, in order to make the surface of the workpiece can meet the size of the drawings, geometric shapes and the accuracy of the location with other surfaces and other technical requirements, the workpiece must be installed before the workpiece (positioning), clamp (clamping) The
The fixture is usually set by the positioning element (to determine the correct position of the workpiece in the fixture), the clamping device, the knife guide element (to determine the relative position of the tool and the workpiece or guide the direction of the tool), indexing device (so that the workpiece in a single installation Complete the processing of several stations, there are rotary indexing device and linear moving indexing device two types), connecting components and fixture (fixture base) and other components.
The type of fixture according to the use of characteristics can be divided into:
Universal universal fixture. Such as machine vise, chuck, sucker, dividing head and rotary table, etc., have great versatility, can better adapt to the processing and processing of the transformation of the object, its structure has been stereotypes, size, specifications have been series Of which most of them have become a standard accessory for machine tools.
② special fixture. For a product parts in a process on the need for clamping and design and manufacturing, service object specific, highly targeted, generally designed by the product manufacturer. Commonly used lathe fixture, milling machine fixture, drill mold (tooling tool for drilling or reaming holes in the workpiece), boring mold (machine tool grips for guiding boring rods in the workpiece) and accompanying jigs In the combination of machine tools on the automatic line of mobile fixture).Welding Fixture
③ adjustable fixture. A special fixture that can be replaced or adjusted.Welding Fixture
④ combination fixture. Clamps made up of standardized components of different shapes, specifications and applications are suitable for single product, small batch production and temporary tasks for new product trial and product replacement.
In addition to the vise, chuck, sub-head and rotary table and the like, there is a more common called handle, in general, the tool fixture when the word appears, most of the fixture refers to the handle.Welding Fixture
