What kind of clips are there
- Jul 13, 2018 -

The fixture usually consists of a positioning element (determining the correct position of the workpiece in the fixture), a clamping device, a tool guiding element (determining the relative position of the tool to the workpiece or guiding the tool direction), and an indexing device (to enable the workpiece to be installed in a secondary installation) Complete the processing of several stations, including rotary indexing device and linear moving indexing device), connecting components and clip specific (clamp base). For example, welding fixtures, inspection fixtures, assembly fixtures, machine tool fixtures, etc., where machine tool fixtures are the most common, often referred to as fixtures. When machining the workpiece on the machine tool, in order to make the surface of the workpiece reach the technical requirements of the specified size, geometric shape and mutual positional accuracy with other surfaces, the workpiece must be positioned and clamped before machining.

The types of fixtures can be divided into: 1 universal universal fixtures such as machine vices, chucks, suction cups, indexing heads and rotary tables, etc., which have great versatility and can be well adapted to the processing steps and processing objects. The transformation, the structure has been finalized, the size, the specifications have been serialized, and most of them have become a standard attachment for machine tools. 2 special fixtures. It is specially designed and manufactured for the clamping needs of a certain product part in a certain process. The service object is specific and highly targeted, and is generally designed by the product manufacturer. Commonly used are lathe fixtures, milling fixtures, drills (machine tool holders for guiding tools to drill holes or reaming on workpieces), die cutters (machine tool holders for guiding the boring bar on the workpiece) and pallets (for The movable clamp on the automatic line of the combined machine tool).3 adjustable clamp. A special fixture that can replace or adjust components. 4 Combination fixture. A fixture consisting of standardized components of different shapes, sizes and uses, suitable for single-piece trials of new products and frequent replacement of products, small batch production and temporary tasks. In addition to vise, chuck, head and rotary table, there is a more common called shank. Generally speaking, when the term tool holder appears at the same time, most of the fixture refers to the shank.

Lathe fixture

The jig used to machine the inside and outside of the workpiece on the lathe is called a lathe fixture. Most of the lathe fixtures are mounted on the spindle and a few are mounted on the saddle or bed.

Three-coordinate fixture

Used on the measuring machine, with its modular support and reference device, the flexible fixing of the workpiece is completed. The device is capable of automatic programming to support the workpiece and establish an infinite workpiece configuration reference point. Advanced dedicated software that produces the workpiece's setup process in seconds, simply through the geometry of the workpiece.

Industrial robot fixture

They are all installed on industrial robots and are used in industrial automation equipment. They are one of the new technologies of modern industrial automation equipment. The main form of cooperation with robots appears in modern industrial production. Common usages are machine loading and unloading, workpiece unloading, welding, grinding and other automated unmanned factories.

Milling fixture

They are all installed on the milling machine table, and the random bed table is used for feeding motion. Mainly composed of positioning device, clamping device, clip specific, connecting component and tool setting component. When milling, the cutting force is large, and the cutting is interrupted and the vibration is large. Therefore, the clamping force of the milling fixture is required to be large, and the rigidity and strength requirements of the fixture are relatively high.

Housing fixture

In order to ensure the quality of the bearing housing and improve the production quality of the bearing housing, in addition to the use of mechanical equipment such as machine tools, a large number of process equipment is used, including bearing housing clamps, molds, tools and related auxiliary tool bearings. The seat clamp is a production tool specially designed to ensure the quality of the bearing housing, which makes the production process of the bearing housing more convenient. Different bearing block fixtures, according to their different structures and forms, working conditions, design principles will be different, so the types and styles of bearing housing clamps are diverse, both in terms of quantity and style. . This type of housing clamp can be used to accurately determine the relative position of the workpiece and the props, that is, the workpiece to be machined can be tightened, so that the movement required during the machining of the workpiece can be completed. Since the bearing housing clamp plays a very important role in the production process of the bearing housing, the drawing of the bearing housing fixture design is also very important.
