German iba workholding fixtures iba model iba price

iba workholding fixtures are devices that hold objects for manipulation. They can grip and release objects while performing certain actions. Motion devices often mimic human movement; in the case of grippers, they mimic finger movement. The "fingers" themselves are not part of the gripper; they are specialized custom tools for holding objects, called "jaws." Two main gripping actions: External gripping: This is the most common method for holding objects. It is the simplest and requires the shortest stroke length. When the gripper jaws close, the clamping force applied by the gripper holds the object. Internal gripping: In some applications, due to the object's geometry or the need to access the exterior of the object, it is necessary to grip the object from the center. In this case, the gripper holds the object through expansion force.

iba workholding fixture applications

Whether it is a simple hydraulic fixture or a complex integrated production line, the design process for hydraulic fixtures is the same, proceeding in the following order: formulation of the overall scheme, selection of hydraulic cylinder types and specifications, selection of control valves, design of mechanical components, selection of pump station accessories, and system connection. Hydraulic fixtures provide powerful clamping and positioning forces for various machining processes. Yun Dongli hydraulic cylinders are used for positioning and clamping in automated machining processes. Products such as self-centering vises and self-centering clamping elements provide good positioning; swing cylinders and lever cylinders provide clamping force on the product; and support cylinders prevent deformation of the product during machining. From simple fixturing to robot-assisted machining centers, hydraulic cylinders provide clamping and support forces to improve production efficiency.

The mechanical gripper-type end effectors applied in loading and unloading industrial robots are mostly two-finger claw types. If classified by finger motion, they can be divided into translational and rotary types. If classified by mechanical clamping method, they can be divided into external clamping and internal expanding types. If classified by mechanical structural characteristics, they can be divided into electric (electromagnetic), hydraulic, and pneumatic types, as well as their combinations. When the end effector clamps the workpiece, there should be certain force constraints and shape constraints to ensure that the clamped workpiece is completely released during movement, dwelling, and loading. In addition, it should ensure that the geometric deviation of the workpiece clamping posture reproduction is within the given tolerance zone.

iba workholding fixture usage

With the continuous development of China's industry, the use of electromagnetic chucks in industrial production is becoming more widespread. The most important aspect of an electromagnetic chuck is its parameters, and among the performance parameters of electromagnetic chucks, the lifting capacity and its working class are the most critical. The so-called lifting capacity of an electromagnetic chuck refers to the maximum weight of objects allowed to be lifted under specified working conditions, or in other words, the rated lifting capacity. Generally, the lifting capacity of cranes equipped with electromagnetic chucks should also include the weight of the electromagnetic chuck. Rectangular electromagnetic chucks have lifting screw holes on both sides; during installation, T-shaped screws can be screwed in for lifting. They are fixed to the workbench using T-shaped blocks and screws. Connect the DC power supply and ground wire from the machine tool, then precision grind the upper plane of the chuck once to ensure the parallelism between the upper plane and the bottom surface. When adsorbing the workpiece, sufficient positioning suction force can be obtained by bridging two adjacent magnetic poles, allowing grinding processing to proceed. Magnetization and demagnetization of the workpiece can be achieved through the machine tool buttons. Before using the electromagnetic chuck, wipe the surface clean to avoid scratches. Severe impacts are not allowed, as they may affect precision. After use, wipe it clean and apply anti-rust oil to prevent corrosion. When using the electromagnetic chuck alone, a ground wire should be connected to prevent electric shock from leakage.
