10 Rotary Clamp Cylinder Manufacturers in 2023
This section provides an overview for rotary clamp cylinders as well as their applications and principles. Also, please take a look at the list of 10 rotary clamp cylinder manufacturers and their company rankings.
What Is a Rotary Clamp Cylinder?
A clamping cylinder is a machine tool often used in automated production lines to clamp (fix) a workpiece (to be machined) in order to perform a work process, such as drilling by a work robot or spot welder.
The clamping cylinder fixes the workpiece during the work process by using pneumatic or hydraulic pressure to move the cylinder part, called the rod, up and down or left and right, in a linear motion.
A rotary clamp cylinder is a clamp cylinder with a rotating mechanism added to the rod.
Uses of Rotary Clamp Cylinders
Clamp cylinders are used to clamp workpieces in automated production lines.
Rotary clamp cylinders are used for clamping during machining or welding operations only. They are designed to save space so that the clamping point does not interfere with the workpiece flow during loading and unloading before and after the machining or welding operations.
The clamping arm, called a clamp lever, swivels and clamps the workpiece so that when it is not clamped, it does not interfere with the next loading or unloading process on the line, thus enabling compact equipment design and space saving in automated lines.
Principle of Rotary Clamp Cylinders
The rod of rotary clamp cylinders is swiveled by a cam mechanism using a groove on the rod.
When clamping workpieces at two locations on the left and right sides of an automated line, the direction of rotation of the left and right clamp levers should be reversed to shorten the time required for rotational motion. Rotary clamp cylinders are available for such applications.
The drive source of the clamp cylinder can be either pneumatic, using compressed air, or hydraulic, but when a particularly large clamping force is required, hydraulic pressure is usually used.
Although the rotary clamp cylinders strokes while the piston rod swivels, many models cannot handle simultaneous control of the clamping while the clamp lever is in the process of swiveling, so care must be taken when handling them.
There is an acceptable trade-off correlation between the allowable clamp lever length and clamp pressure, and between the allowable moment of inertia of the clamp lever and the piston speed for each model. In particular, the calculation of the moment of inertia depends on many factors, such as field usage, clamp lever shape and length, and various specifications, such as weight, so it is advisable to check the specifications carefully with the manufacturer before use.
Furthermore, some models are capable of horizontal operation, while others are not. It is important to select the model and manufacturer in accordance with the overall equipment design of the automation line.
