German innotool workpiece clamping fixtures innotool model innotool price

innotool workpiece clamping fixture is an electromagnetic chuck that secures the workpiece being machined by the suction force generated by the chuck body when the electromagnetic coil is energized. The electromagnetic chuck consists of several parts, including an iron core, coil, faceplate, and bracket. The electromagnet, composed of the coil and iron core, is the main part of the electromagnetic chuck. Electromagnetic chucks vary due to differences in design methods or materials used, and they are continuously developing and improving. Electromagnetic chucks were initially used on grinding machines to replace clamps 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, and its application has significant limitations. With industrial development, the demand for electromagnetic tools from enterprises is increasing, and the requirements proposed are becoming higher, prompting a series of improvements to electromagnetic chucks to meet production needs.

innotool workpiece clamping fixture requirements

Whether clamping or suction-type, the robot end-effector must also 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 rather than general-purpose robot end-effectors have a simpler structure, high work efficiency, and can perform various operations. In contrast, "universal" end-effectors may have disadvantages such as complex structure and high cost. Therefore, it is advocated to design and use serialized and standardized dedicated robot end-effectors that can be quickly replaced. If the object has two opposing flat surfaces, a parallel two-jaw gripper can be used to address dimensional deviation issues. For cylindrical objects, a two-jaw gripper can also be used for clamping. It should be noted that containment or enveloping gripping requires less force.

innotool workpiece clamping fixture principles and features

The structure of a flat vacuum suction cup consists of the suction cup and the suction cup holder. The flat vacuum suction cup is first connected to vacuum equipment, such as a vacuum generator, via a connecting pipe, and then comes into contact with the object to be lifted, such as glass or paper. The vacuum equipment is started to create negative pressure inside the suction cup, securely holding the object for transportation. When the object reaches its destination, air is gently introduced into the vacuum suction cup, changing the internal pressure from negative to zero or slightly positive, allowing the suction cup to release the object and complete the lifting task. 1) High wear rate. Since it is typically made of rubber and directly contacts objects, it experiences significant wear and tear, leading to rapid deterioration. It is considered a pneumatic consumable component. This characteristic makes it stand out among many other pneumatic components. 2) Easy to use. Regardless of the material of the object being lifted, as long as it can form a seal without leaking air, the suction cup can be used. Electromagnetic suction cups, on the other hand, are limited to steel materials and cannot lift plates or objects made of other materials. 3) No pollution. Vacuum suction cups are environmentally friendly, causing no environmental contamination, and do not produce light, heat, or electromagnetic interference. 4) Does not damage workpieces. Made of rubber, vacuum suction cups do not cause any damage when picking up or placing workpieces. Hook-type and cable-type lifting devices, however, may cause damage. In some industries where surface quality requirements are strict, only vacuum suction cups can be used.

innotool workpiece clamping fixture usage

With the continuous development of industry in our country, 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, 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 allowed to be lifted under specified working conditions, or alternatively, the rated lifting capacity. Generally, the lifting capacity of a crane equipped with an electromagnetic chuck should also 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 attracting workpieces, 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 via machine tool buttons. The surface of the electromagnetic chuck should be wiped clean before use to avoid scratches. Severe impacts are prohibited to avoid affecting precision. After use, it should be cleaned and coated with anti-rust oil to prevent corrosion. When using an electromagnetic chuck alone, a ground wire should be present to prevent electric shock from leakage.
