Do you all understand? In the operation, we must first understand the scope of our work and what it includes. Xiaobian sorted out nine kinds for everyone. In the process of use, how to clamp the workpiece firmly? This will use clamps. Today, I will summarize the fixtures we often use in operation. The following is a detailed introduction. I hope it can help you. For more information, please click on our website to read the details. thank you!

1、 Common fixture summary

1. Chuck. The chuck can be said to be familiar with our robots and can't be used in a familiar fixture. Chuck has a history of 100 years. It can be said to be a very classic fixture.

2. T-table. T-type workbench can be said to be very classic, and there are T-type workbench in some places.

3. T-block, screw, pressing plate and nut. It is difficult to imagine how to clamp the workpiece on the machine tool without these combinations.

4. Bench Vise and toast. Workpieces that cannot be pressed by the pressing plate can be considered to use Bench Vise or toast clamp.

5. Magnetic platform. The magnetic platform is convenient but relatively expensive.

6. Spindle and tool handle. The crystallization of human wisdom and technology.

7. Spring jacket / barrel. With it, a tool handle can realize the clamping of different specifications of tools.

8. Cylinder clamp. The essence of automatic fixture.

9. Indexing head. It used to be very beautiful. With the emergence of the indexing spindle, it gradually declined.

2、 Classification of tooling fixtures

1. Classification of machine tool fixtures

(1) Classification by degree of specialization

1) Universal fixture

General fixture refers to the fixture that has been standardized and can be used to process different workpieces within a certain range.

For example, three jaw chuck and four jaw single action chuck on lathe, flat tongs, indexing head and rotary table on milling machine, etc. This kind of fixture is generally produced by professional factories and often provided to users as machine tool accessories.

It is characterized by wide adaptability and low production efficiency, and is mainly applicable to single piece and small batch production.

2) Special fixture

Special fixture refers to the fixture specially designed for a certain process of a workpiece.

It is characterized by compact structure, rapid operation, convenience and labor saving, which can ensure high processing accuracy and production efficiency, but the design and manufacturing cycle is long and the manufacturing cost is high.

When the product is changed, the fixture will be scrapped because it can no longer be used.

It is only applicable to the production with fixed products and large batches.

3) Universal adjustable fixture and Group Fixture

Its features are that some components of the fixture can be replaced and some devices can be adjusted to adapt to the processing of different parts.

The fixture used for group processing of similar parts is called group fixture.

Compared with the group fixture, the processing object of the universal adjustable fixture is not very clear, and the application range is wider.

4) Combined fixture

Combined fixture refers to the fixture assembled by a set of standard components and parts manufactured in advance according to the processing requirements of parts.

It is characterized by flexible and changeable, short manufacturing cycle and repeated use of components, especially suitable for trial production of new products and small batch production of single piece.

5) Traveling fixture

Traveling clamp is a kind of clamp used on automatic line.

The fixture not only plays the role of clamping the workpiece, but also moves from one station to the next along the automatic line to process different processes.

(2) Classification by machine tool used

Due to the different working characteristics and structural forms of various machine tools, different requirements are put forward for the structure of the fixtures used.

According to the different machine tools used, the fixtures can be divided into: lathe fixture, milling machine fixture, drilling machine fixture, boring machine fixture, grinding machine fixture, gear machine fixture and other machine tool fixtures.

Drill jig

Drill jig is short for drill jig, which is mainly used to process holes and threads. It is mainly composed of drill sleeve, drill template, positioning and clamping device and clamp.

Boring machine fixture

Boring machine fixture, also known as boring die, is mainly used to process precision holes and hole systems on box or support parts. It is mainly composed of boring die base, support, boring sleeve, boring bar and necessary positioning and clamping device.

(3) Classified by clamping power source

According to the different clamping power sources used by the clamp, it can be divided into: manual clamp, pneumatic clamp, hydraulic clamp, gas-liquid clamp, electric clamp, magnetic clamp, vacuum clamp, etc.

The above is the summary of commonly used fixtures and the classification of tooling fixtures compiled by the small editor. I hope it can be helpful to you. Those who are interested can collect and pay attention to it
