A clamp, also known as a fixture, is a tool used to fix or clamp an object. Clamp is easy to use, powerful, widely used in machinery, electrical appliances, automobiles, aviation, shipbuilding, construction and other fields. It plays an important role in industrial production and personal DIY.
Clamp types and shapes are more, according to different uses to classify, can be divided into the following:
First, manual clamp: This kind of clamp is generally relatively small, suitable for manual operation. Mostly used in precision machining, assembly and other fields. According to the functional classification, it can generally be divided into the following categories:
1. Flat-mouth clamp: The chuck plane is straight, used to fix the work piece, is the most common model in the fixture.
2. Curved nose clamp: the end face of the clamp has a certain bend, suitable for dealing with round objects, such as nails, iron wire, etc.
3. Diagonal clamp: The incline of the chuck is at a 45 degree Angle, which is often used for clamping inclined objects.
4. Crank clamp: The clamp handle is parallel and lengthened to make its clamping force greater. Suitable for clamping large shape, high fixed requirements of the workpiece.
5. Ring clamp: The clamp head is semicircular and bent, used to fix pipes, steel pipes and other objects.
Second, mechanical clamp: This type of clamp needs to rely on mechanical force to work, and is faster and more efficient than manual clamp. There are many types of mechanical clamps, and the most common ones include:
1. Automatic clamp: Automatic clamp is a type of clamp controlled by a transmission mechanism or pneumatic device. Automatic clamp usually adopts self-locking mechanism, which has large clamping force, good stability and fast clamping speed.
2. CNC clamp: CNC clamp is a powerful CNC machine tool necessary accessories. CNC clamp is an integrated system of electricity, gas and water control, which can react the clamp state and pressure.
3. Pneumatic clamp: Pneumatic clamp is a clamp using compressed air as a power source. Since air is a widespread medium, it is easy to construct and maintain.
Third, special clamp: This clamp is more special, according to the specific use, the shape and working principle of the clamp have great differences.
1. Fitter centering device: It is specially used for clamping irregular workpieces, such as wheels, gears, plain bearings, etc. The internal structure adopts the principle of expansion and reduction, and the clamping force is large and does not harm the workpiece surface.
2. Special-shaped fixture: It is a fixture for processing and repairing special-shaped workpieces. According to different special-shaped workpiece shapes, different clamps can be used to clamp.
As an important tool, clamp is widely used in industrial production, machinery manufacturing and construction. It can not only ensure production quality, but also improve work efficiency. It has also been widely used in most DIY fields, becoming a good helper for enthusiasts to complete their own projects.
