German ferra tools workpiece fixtures, ferra tools models, ferra tools prices

ferra tools workpiece fixtures are tools with specific functions connected to the edge (joint) of a robot. This may include robot grippers, robot tool changers, robot collision sensors, robot rotary unions, robot pressure tools, compliance devices, robot spray guns, robot deburring tools, robot arc welding torches, robot electric welding torches, etc. Robot end-effectors are generally considered peripheral equipment of the robot, robot accessories, robot tools, or arm-end tools (EOA). Key elements: mechanism type, gripping method, gripping force, drive unit and control object characteristics, mass, shape, center of gravity position, dimensions, dimensional tolerances, surface condition, material, strength; operating parameters: operating space environment, operating accuracy, operating speed and acceleration, clamping time.

ferra tools workpiece fixture applications

Whether it is a simple hydraulic clamping fixture or a complex integrated production line, the design process for hydraulic clamping fixtures follows the same sequence: formulation of the overall scheme, selection of hydraulic cylinder types and specifications, selection of control valves, design of mechanical components, selection of pump station accessories, and system connection. Hydraulic clamping fixtures provide powerful clamping and positioning forces for various machining processes. Yun Dongli hydraulic cylinders are used for positioning and clamping in automated machining processes. Products such as self-centering vises and self-centering clamping elements ensure accurate positioning; swing cylinders and lever cylinders provide clamping force on the workpiece; support cylinders prevent deformation during machining. From simple fixturing to robot-assisted machining centers, hydraulic cylinders provide clamping and support forces to enhance production efficiency.

ferra tools workpiece fixture principles and features

The structure of a flat vacuum suction cup consists of the suction cup and the suction cup holder. First, the flat vacuum suction cup is connected via a pipe to vacuum equipment such as a vacuum generator, then brought 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 so that transport can begin. When the object reaches its destination, air is smoothly 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 pick up plates or objects made of other materials. 3) No pollution. Vacuum suction cups are particularly environmentally friendly, do not pollute the environment, and produce no light, heat, or electromagnetic emissions. 4) Does not damage the workpiece. Because vacuum suction cups are made of rubber, picking up or placing workpieces causes no damage to them. Hook-type and cable-type lifting gear cannot guarantee this. In some industries, where requirements for workpiece surfaces are particularly strict, only vacuum suction cups can be used.

ferra tools workpiece fixture maintenance

When using vacuum suction cups (without clamps), note that the manipulator's movement speed must not be too high; otherwise, shear forces will be generated on the suction cup, causing the product to fall off easily during rapid twisting. In some cases, a clamp can be used to ensure safe transport of the product. Considering that the product may stick to the mold, an air clamp is usually installed to solve this problem. When the product's surface area is too small or the product is too heavy for vacuum suction cups, this problem can also be solved by using clamps. 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 clamp or suction cup has securely held the product, the sensor sends a signal to the manipulator to proceed to 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 forming area, a special cylinder capable of independent movement, not relying on manipulator operation, can be added to improve the situation.
