German innotool workholding fixtures innotool model innotool price

innotool workholding fixture is an electromagnetic chuck that secures the workpiece via suction generated by the chuck body when the electromagnetic coil is energized. The electromagnetic chuck consists of an iron core, coil, faceplate, and bracket. The electromagnet, formed by the coil and iron core, is the main component of the electromagnetic chuck. Electromagnetic chucks vary due to differences in design methods or materials used, and they are continuously developing and improving. Initially, electromagnetic chucks were used on grinding machines to replace clamping plates and bolts for securing workpieces to be ground. Such electromagnetic chucks are relatively simple and can only secure flat workpieces. This is the traditional electromagnetic chuck, which has significant limitations in its application. With industrial development, the demand for electromagnetic tools from enterprises has grown, and requirements have become higher, prompting a series of improvements to electromagnetic chucks to meet production needs.

innotool workholding fixture requirements

Whether clamping or suction-type, the robot end-effector must have the repeatability required for the operation. The structure of the robot end-effector should be as simple and compact as possible, with light weight, to reduce the load on the arm. Dedicated, more general-purpose robot end-effectors have simpler structures but high work efficiency and can perform various operations. In contrast, "universal" end-effectors may have disadvantages such as complex structures and high costs. Therefore, it is recommended to design and use serialized, generalized, dedicated robot end-effectors that can be quickly replaced. If an object has two opposing flat surfaces, a double-jaw parallel gripper can be used to address dimensional deviation issues. For cylindrical objects, a double-jaw gripper can also be used for clamping. Note that retaining or encompassing gripping requires less force.

innotool workholding fixture principles and features

The structure of a flat vacuum suction cup consists of the suction cup and the suction cup collar. First, connect the flat vacuum suction cup to vacuum equipment, such as a vacuum generator, via a pipe joint. Then, bring it into contact with the object to be lifted, such as glass or paper. Start the vacuum equipment to create negative pressure inside the suction cup, securing the object for transport. When the object reaches its destination, gently introduce air into the suction cup to change the internal pressure from negative to zero or slightly positive, allowing the suction cup to release the object, thus completing the lifting and transporting task. 1) High wear. Since it is generally made of rubber and directly contacts objects, it suffers from severe wear and rapid degradation. It is a pneumatic wearable part. This is why it stands out significantly among many pneumatic components. 2) Easy to use. Regardless of the material of the object being sucked, as long as it can be sealed without air leakage, it can be used. Electromagnetic chucks cannot do this; they can only be used on steel materials and cannot lift plates or objects made of other materials. 3) No pollution. Vacuum suction cups are particularly environmentally friendly, causing no environmental pollution, and producing no light, heat, or electromagnetic emissions. 4) Does not damage the workpiece. Since vacuum suction cups are made of rubber, picking up or placing down workpieces will not cause any damage. Hook-type and cable-type lifting gear cannot achieve this. In some industries, where surface requirements for workpieces are particularly strict, only vacuum suction cups can be used.

innotool workholding fixture usage

With the continuous development of China's industry, the use of electromagnetic chucks in industrial production is becoming increasingly widespread. The most important aspect of an electromagnetic chuck is its parameters, with lifting capacity and working class being the primary performance parameters. The so-called lifting capacity of an electromagnetic chuck refers to the maximum weight allowed to be lifted under specified working conditions, also known as the rated lifting capacity. Generally, the lifting capacity of a crane equipped with an electromagnetic chuck should include the weight of the electromagnetic chuck itself. Rectangular electromagnetic chucks have lifting screw holes on both sides; during installation, T-shaped screws can be screwed in for lifting, and 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 parallelism between the upper and bottom surfaces. When adsorbing workpieces, simply bridging two adjacent magnetic poles provides sufficient positioning suction force for grinding operations. 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. Avoid severe impacts to prevent affecting precision. After use, clean thoroughly and apply anti-rust oil to prevent corrosion. When using an electromagnetic chuck independently, a ground wire should be connected to prevent electric shock injuries.
