What is the general classification of fixtures?

The types of fixture can be divided into: ① General fixture. Such as vice, chuck, sucker, indexing head, turntable, etc. , with great versatility, can better adapt to the transformation of machining procedures and machining objects. Their structures have been finalized, their dimensions and specifications have been serialized, and most of them have become standard parts of machine tools. ② Special fixture. Specially designed and manufactured for the clamping requirements of a product part in a certain technological process, the service object is single-minded and targeted, and it is generally designed by the product manufacturer. Commonly used are lathe fixture, milling fixture, drilling fixture (machine fixture that guides the cutter to drill or ream holes on the workpiece), boring fixture (machine fixture that guides the boring cutter to drill holes on the workpiece) and accompanying fixture (movable fixture that assembles the automatic line of the machine tool). ③ Adjustable fixture. Special fixture for replacing or adjusting parts. ④ Combined fixture. Fixtures composed of standardized parts with different shapes, specifications and uses are suitable for trial production of new products and temporary tasks of single-piece and small-batch production and frequent product replacement.

In addition to vice, chuck, indexing head and turntable, there is a common tool rest. Generally speaking, when the word tool holder appears at the same time, this kind of fixture mostly refers to the tool holder.

Lathe fixture

The fixture used to process the internal and external revolving surfaces and end faces of the workpiece on the lathe is called lathe fixture. Most lathe fixtures are installed on the spindle, and a few are installed on the saddle or bed.

Three-coordinate fixture

Used for measuring machine, using its modular bracket and reference device to complete the flexible fixation of the measured workpiece. The equipment can automatically program, support the workpiece and establish infinite reference points for workpiece configuration. Advanced special software can directly generate the workpiece clamping program in a few seconds through the geometric data of the workpiece.

Industrial robot fixture

They are all installed on [1] industrial robots for industrial automation equipment, which is one of the new technologies of modern industrial automation equipment. The main form of cooperation with robots appears in modern industrial production, and its common usage is in automatic unmanned factories such as loading and unloading of machine tools, unpacking and palletizing of workpieces, welding and polishing.

Fraise jig

Installed on the milling machine workbench, the random bed workbench carries out feeding movement. It mainly consists of a positioning device, a clamping device, a clamping body, a connecting element and a tool setting element. When milling, the cutting force is large and the cutting is intermittent, so the clamping force of the milling machine fixture is large and the fixture stiffness and strength are high.

Bearing bracket fixture

In order to ensure the production quality of the bearing seat and improve the production quality of the bearing seat, in addition to mechanical equipment such as machine tools, a large number of process equipment will be used, including bearing seat fixtures, molds, cutters and related auxiliary tools.

Bearing fixture is a kind of production tool specially used to ensure the quality of bearing seat products, which can make the production process of bearing seat more convenient. Different bearing seat fixtures will be different according to their different structural forms, working conditions and design principles, so the types and styles of bearing seat fixtures are also varied, and both the number and the styles account for a large proportion.

This bearing fixture can be used to accurately determine the relative position between the machined workpiece and the pillar, that is, it can tighten the machined workpiece, so as to complete the required movement in the machining process of the workpiece. Because the bearing fixture plays a very important role in the bearing production process, it is also very important to draw the bearing fixture design drawing.
