German haueisen sohn workpiece fixtures, haueisen sohn models, haueisen sohn prices

haueisen sohn workpiece fixtures are one of the actuators for vacuum equipment. Generally, using vacuum suction cups to grasp products is the most economical method. Vacuum suction cups come in various types; rubber suction cups can operate at high temperatures, silicone rubber suction cups are very suitable for grasping products with rough surfaces, and polyurethane suction cups are highly durable. Additionally, in actual production, if oil resistance is required for the suction cup, materials such as polyurethane, nitrile rubber, or vinyl-containing polymers can be considered for manufacturing. Typically, to avoid scratching the product surface, it is best to choose bellows-type suction cups made of nitrile rubber or silicone rubber. The suction cup material is made of nitrile rubber, which has high tensile strength, and is therefore widely used in various vacuum holding devices.

1) Positioning elements: These contact the positioning reference of the workpiece to determine its correct position in the fixture, thereby ensuring the correct relative position between the workpiece and the tool and machine tool movements during machining. 2) Clamping device: Used to clamp the workpiece, keeping it in the established position within the fixture during cutting. As shown in Figure 6-1, such as nut 5 and open washer. 3) Tool setting and guiding elements or devices: These elements ensure the correct position between the workpiece and the tool. Elements used to determine the correct position of the tool before machining are called tool setting elements, such as tool setting blocks. Elements used to determine the tool position and guide the tool during machining are called guiding elements. 4) Connecting elements: Elements that connect the fixture to the machine tool, ensuring the mutual positional relationship between the machine tool and the fixture. 5) Fixture body: The base component used to connect or fix various elements and devices on the fixture into a single unit. It connects and aligns with relevant parts of the machine tool, giving the fixture a definite position relative to the machine tool. 6) Other elements and devices: Some fixtures require indexing mechanisms based on workpiece machining requirements, and milling machine fixtures also require positioning keys, etc. Not all of these components are indispensable for every type of machine tool fixture, but any fixture must have positioning elements and clamping devices, as they are key to ensuring workpiece machining accuracy, with the aim of accurately locating and firmly clamping the workpiece.

haueisen sohn workpiece 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 first connects the vacuum suction cup to vacuum equipment, such as a vacuum generator, via a pipe joint, then contacts the object to be lifted, such as glass or paper. Starting the vacuum equipment creates negative pressure inside the suction cup, securely holding the object to be lifted, allowing transport to begin. 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, causing the suction cup to release the object, thus completing the lifting and transport task. 1) High wear. Since it is generally made of rubber and directly contacts objects, it suffers severe wear and deteriorates quickly. It is a pneumatic wearable part. Precisely because of this, 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, and cannot suck plates or objects made of other materials. 3) No pollution. Vacuum suction cups are particularly environmentally friendly, do not pollute the environment, and do not produce light, heat, or electromagnetic fields. 4) Does not damage the workpiece. Since vacuum suction cups are made of rubber material, picking up or placing down the workpiece causes no damage to it. 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.

haueisen sohn workpiece fixture maintenance

When using vacuum suction cups (without grippers), note that the manipulator's movement speed should not be too high, otherwise shear forces will be generated on the suction cup, causing the product to easily drop during rapid twisting. In some cases, a gripper can be used to ensure safe transport of the product. Considering that the product may stick to the mold, an air gripper is usually installed to solve this problem. When the product surface area is too small or the product is too heavy for vacuum suction cups, this problem can also be solved by using grippers. If the product has strict appearance requirements, the clamped area must not be the outer surface. To solve this problem, a sensor circuit can be installed. After confirming that the gripper or suction cup has securely held the product, the sensor sends a signal to the manipulator to proceed with the next operation. In cases where the manipulator's motion capability is limited and manual twisting or prying is required to demold the product or move it out of the molding area, a special cylinder capable of independent movement, not relying on manipulator operation, can be added to improve this situation.
