A linear clamper is a clamp for holding the position of a table or stage in machining operations, etc. It is attached directly to the linear guide and clamped to fix the position. Also called a linear brake, there are products that are pneumatically operated and products that are opened and closed with a manual lever.
Linear guides are widely used in machining operations, etc., but the movable table has been controlled by attaching a stopper to the guide with bolts or by using a balance cylinder to fix the guide. However, the former requires time-consuming repositioning and can only be installed manually, while the latter has issues in terms of equipment size and accuracy. The linear clamper can be integrated into automatic control systems, and its compactness and precision in position control make it possible to solve these problems.
Linear clampers are used to fix the position when working with linear guides and used in all operations that use linear guides. Especially in machining operations using automatic control technology such as motion control, the use of linear guides is common, and linear clampers are also widely used for holding and positioning the work table. In these machining operations, abnormal vibration called "chatter" can cause a loss of machining accuracy, and the use of linear clampers contributes to preventing the occurrence of chatter.
Specific applications of linear clampers include machining operations that involve vibration, such as drilling, drilling, and grinding. They are also used in applications for holding the position of presses and other machines that handle heavy loads during emergency stoppages.
The use of linear guides in machining operations has been widely used in terms of position retention and chatter prevention, but has become more important in recent years with the generalization of motion control systems.
Motion control systems must automatically perform precise positioning of the worktable, but the conventional control method using balance cylinders, etc., for stationary motion in particular, has been problematic because of the imbalance between positional accuracy and the size, weight, and cost of the equipment.
The linear clampers are a direct braking mechanism that clamp the guide, enabling position control in a smaller space and with greater precision than conventional methods. The manually clamped linear clampers are also more convenient and infinitely adjustable than conventional bolted clamping, and the clamping position makes it possible to check whether it is open or closed visually, making it a useful piece of equipment in terms of accuracy and safety. Furthermore, when adding the system to existing equipment, the structure of the system is directly attached to the linear guide, so there is no need for large-scale modifications or changes in the design of the table size.
