ebag fixtures, German ebag models, ebag prices

ebag fixtures use hydraulic components to replace mechanical parts, achieving automatic positioning, support, and clamping of workpieces through hydraulic control. They offer advantages such as high clamping force, reliable clamping, stable operation, and ease of use. They are currently widely used in scenarios such as CNC machine tools, machining centers, and automated production lines. By assembling selected hydraulic components with the designed mechanical parts, the required fixture can be obtained. Hydraulic fixtures ensure accurate positioning and secure clamping of the workpiece at specified positions, reduce vibration and deformation during machining through floating supports, and can utilize automatic control to press down and lift clamp plates to clear the clamping position during machining. Hydraulic fixtures can withstand large cutting forces during rough machining, ensure accurate positioning during precision machining, and perform support, clamping, and quick release tasks that manual fixtures cannot accomplish.

ebag fixture working principle

The most widely used grippers are pneumatic grippers; they are essentially cylinders powered by compressed air. When air is supplied, the gripper jaws approach the object and firmly grasp it to perform other operations, and when the air direction is reversed, the gripper releases the object. Typical applications include changing the orientation of an object or moving the object in pick-and-place operations. When the gripper holds 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. In addition, it should ensure that the geometric deviation of the workpiece holding posture is within the specified tolerance zone.

ebag fixture features

1) Suction cup holding force: Electrically controlled powerful suction cups have extremely strong holding force, up to 16kg/cm², with uniform and adjustable magnetic distribution, suitable for various heavy-duty machining, rough machining, and precision machining; ordinary powerful suction cups have weaker and unevenly distributed holding force, unable to meet the requirements of heavy-duty machining operations. 2) Machining accuracy: The holding force of electrically controlled powerful suction cups does not require a continuous power supply to maintain, generating no heat during continuous operation, avoiding thermal deformation of the workpiece. Meanwhile, the strong and uniform surface suction ensures the highest machining accuracy even if the workpiece extends beyond the table surface; whereas ordinary electromagnetic suction cups require a continuous current supply, generating heat after a period of operation, which not only causes thermal deformation of the workpiece but also reduces the magnetic force of the suction cup, failing to guarantee machining accuracy. 3) Performance: Electrically controlled powerful suction cups can be used continuously, even operating for more than 20 hours daily without any faults or need for maintenance; ordinary permanent magnet suction cups show a decline in holding force after about half a year of use, while electromagnetic suction cups can only operate for a few hours a day, are prone to failures, and require frequent replacement and repair of internal components. 4) Operational efficiency: Using ordinary powerful suction cups requires significant time for workpiece adjustment, accounting for 40%-50% of the entire machining process. Clamping and positioning are prone to obvious errors, resulting in high scrap rates and very low efficiency; electrically controlled powerful suction cups feature automatic auxiliary positioning, completing workpiece clamping or release in just 0.3 seconds with the simple press of a button, significantly improving production efficiency.

ebag fixture selection and usage

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, and among the performance parameters of an electromagnetic chuck, the most critical are the lifting capacity and its working class. The so-called lifting capacity of an electromagnetic chuck refers to the maximum weight of objects allowed to be lifted under specified working conditions, or in other words, 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. There are lifting screw holes on both sides of the rectangular electromagnetic chuck. During installation, T-shaped screws can be screwed in for lifting, and T-shaped blocks and screws are used to fix it on the workbench. Connect the DC power supply and ground wire on the machine tool, and then precision grind the upper plane of the chuck once to ensure the parallelism between the upper plane and the bottom plane. When adsorbing the workpiece, as long as two adjacent magnetic poles are bridged, sufficient positioning suction force can be obtained, allowing grinding processing to proceed. Through the machine tool buttons, magnetization and demagnetization of the workpiece can be achieved.
