German swt workholding fixtures swt model swt price

swt workholding fixture is an electromagnetic fixture that secures the workpiece by the suction force generated by the chuck body when the electromagnetic coil is energized. The electromagnetic chuck consists of several parts, including a core, coil, faceplate, and bracket. The electromagnet, composed of the coil and 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 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 the requirements have become higher, prompting a series of improvements to electromagnetic chucks to meet production needs.

swt workholding fixture introduction

Vacuum suction cups are one of the actuators in vacuum equipment. The suction cup material is made of nitrile rubber, which has high tensile strength, and is therefore widely used in various vacuum holding devices, such as in construction, paper industry, printing, and glass industries, to perform tasks of holding and transporting thin and light items like glass and paper. Vacuum suction cups are also known as vacuum lifters and vacuum nozzles. Generally, using vacuum suction cups to grasp products is the most cost-effective method. There are various types of vacuum suction cups; 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. 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. Typically, to avoid scratching the surface of the product, it is best to choose suction cups with bellows made of nitrile rubber or silicone rubber.

swt workholding fixture structure

The mechanical gripper-type end effectors used in loading and unloading industrial robots are mostly two-finger claw types. According to the motion of the fingers, they can be divided into translational and rotational types. According to the mechanical clamping method, they can be divided into external clamping and internal expansion types. According to the mechanical structural characteristics, they can be classified as 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 processes. In addition, it should ensure that the geometric deviation of the workpiece clamping posture reproduction is within the given tolerance zone.

swt workholding fixture maintenance

1) Check before use whether the limit dimensions are still in the correct position. 2) If the stop pin wear exceeds tolerance, it can be repaired by grinding; if the baffle, pin, or positioning taper pin wear exceeds tolerance, it can be reassembled, shifting the worn areas to continue use. 3) Apply anti-rust oil after use. Regular long-term lubrication can maintain the life of the synchronous fixture; incorrect lubrication will lead to reduced clamping force, poor accuracy, wear, and jamming, so correct lubrication is essential. After machining, be sure to clean the synchronous fixture body and slide ways with an air gun or similar tool. During cleaning, remove the dust cover fixing screws and take off the dust cover, while opening the main jaws to the widest position to easily clean chips accumulated inside the fixture. To avoid reduced clamping force due to rust, use rust-preventive cutting oil. Remove the synchronous fixture every six months for thorough cleaning (at least every two months when machining cast iron or copper products). Check parts for damage or wear, and replace with new ones immediately if severe. Lubricate thoroughly before assembly.
