The role of fixture parts processing in CNC machining

As those who do CNC machining know, the tooling fixture is the processing equipment, which is the general name of various tools used in the CNC machining and production process, including cutting tools, fixtures, molds, inspection tools, auxiliary tools , Fixtures, fitter tools, station appliances, etc. Its main meanings are as follows:

1. Tool: The tool used in mechanical manufacturing is basically used to cut metal materials, so the term 'tool' is generally understood as a metal cutting tool;

2. Fixture: to put it bluntly, it is a device used to clamp the workpiece (or guide tool);

3. Mold: a device used to determine the shape and size of the product;

4. Inspection tools: tools used for production inspection;

5. Auxiliary tools: usually used to connect tools and machine tools;

6. Fixtures: used for Manufactured utensils, the word corresponds to fixtures, sometimes synonymous with tools, and sometimes also refers to fixtures, this term is often used in electronics companies such as Taiwanese/Korean/Japanese;

7. Fitter Tools: the general name of various tools used in the pincer industry;

8. Workstation appliances: various equipment used to store production items or tools in the workplace or warehouse.

The tooling fixture is just a general abbreviation. The tooling fixture belongs to the tooling, and the tooling includes the fixture, which belongs to the subordinate relationship. So what do the fixture parts generally do? Let's see it together

Function 1: Positioning device

The positioning elements and their combinations of CNC machining fixtures are used to determine the position of the workpiece in the fixture, that is, through CNC machining Machining, we can make the workpiece in the position relative to the tool and cutting forming movement, such as support nails, support plates, V-shaped blocks, positioning pins, etc.

Function 2: Clamping device

The function of the CNC machining fixture is to compress the workpiece so that the workpiece occupies the position during positioning It will not be displaced due to external forces such as gravity, inertial force and cutting force, while preventing or reducing vibration. It is generally a clamping mechanism, including clamping elements (such as jaws, pressure plates, etc.), boosting and driving devices (such as levers, threaded transmission pairs, wedges, cams, etc.) and power devices (such as air cylinders, oil cylinders, etc.), etc.

Function three: tool setting-guidance device

Its function is to determine the relative position of the fixture and the tool, or to guide the tool processing, such as Knife blocks, drill sleeves, boring sleeves, etc.

Four four: other components and devices

According to the special functional requirements of the fixture, the indexer, the tool ejector, the upper and lower Feeders and other tooling.

Five functions: clamp body

It is used to connect the various parts and devices of the clamp into a whole, as a basic part, and with the machine tool The relevant parts of the connection are connected to determine the relative position of the fixture and the machine tool.
