German Norlem workholding fixtures Norlem model Norlem price

Norlem workholding fixtures are devices that grip objects to manipulate them. They can clamp and release objects while performing certain actions. Motion devices often mimic human movements; in the case of grippers, they mimic finger movements. The "fingers" themselves do not belong to the gripper; they are merely specialized custom tools for gripping objects, called "jaws." Two main gripping actions: External gripping: This is the most common method for gripping objects. It is the simplest and requires the shortest stroke length. When the gripper jaws close, the clamping force applied by the gripper will hold the object. Internal gripping: In some applications, due to the geometry of the object 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 will hold the object through expansion force.

Norlem workholding fixture introduction

Vacuum suction cups are one of the actuators for vacuum equipment. The suction cup material is made of nitrile rubber, which has high tensile strength, so it is widely used in various vacuum holding equipment, such as in construction, paper industry, printing, glass and other industries, to achieve the task of holding and transporting thin and light items such as glass and paper. Vacuum suction cups are also known as vacuum lifters and vacuum nozzles. Generally speaking, using vacuum suction cups to grab products is the most inexpensive method. There are various types of vacuum suction cups. Rubber suction cups can operate at high temperatures. Suction cups made of silicone rubber are very suitable for grabbing products with rough surfaces. Suction cups made of polyurethane are very durable. In addition, 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 the suction cup. Usually, to avoid scratching the surface of the product, it is best to choose suction cups with bellows made of nitrile rubber or silicone rubber.

Norlem workholding fixture principles and features

The structure of a flat vacuum suction cup consists of the suction cup and the suction cup collar. For a flat vacuum suction cup, first connect the vacuum suction cup to vacuum equipment such as a vacuum generator via a pipe, then contact the object to be lifted such as glass or paper, start the vacuum equipment to suck, creating negative pressure inside the suction cup, thereby firmly holding the object to be lifted, and then begin transporting the object. When the object to be lifted is transported to the destination, air is smoothly inflated into the vacuum suction cup, changing the negative pressure inside the vacuum suction cup to zero pressure or slightly positive pressure, causing the vacuum suction cup to detach from the object, thus completing the task of lifting and transporting heavy objects. 1) Easy to wear out. Since it is generally made of rubber and directly contacts objects, it suffers severe wear and thus wears out quickly. It is a pneumatic wearing 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 seal and not leak air, it can be used. Electromagnetic chucks cannot do this; they can only be used on steel, and plates or objects made of other materials cannot be sucked. 3) No pollution. Vacuum suction cups are particularly environmentally friendly, do not pollute the environment, and produce no light, heat, or electromagnetic effects. 4) Does not damage the workpiece. Since vacuum suction cups are made of rubber material, picking up or putting down the workpiece will not cause any damage to the workpiece. Hook-type lifting gear and cable-type lifting gear cannot do this. In some industries, there are particularly strict requirements for the workpiece surface, and they can only use vacuum suction cups.

Norlem workholding fixture selection and use

With the continuous development of China's industry, electromagnetic chucks are increasingly widely used in industrial production. The most important aspect of an electromagnetic chuck is its parameters; 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 of the load allowed to be lifted under specified operating conditions, also known as the rated lifting capacity. Generally, for cranes equipped with electromagnetic chucks, the lifting capacity should also include the weight of the electromagnetic chuck itself. Rectangular electromagnetic chucks have lifting threaded 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 perform a precision grind on the upper surface of the chuck to ensure the parallelism between the upper surface and the bottom surface. When holding workpieces, sufficient positioning holding force can be obtained by bridging two adjacent magnetic poles, allowing grinding operations to proceed. Magnetization and demagnetization of the workpiece can be controlled via the machine tool buttons.
