German HERZOG workholding fixtures HERZOG model HERZOG price

HERZOG workholding fixtures are any tools with specific functions connected to the robot edge (joint). This may include robot grippers, robot tool changers, robot collision sensors, robot rotary unions, robot force 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, and arm-end tools (EOA). Main elements: mechanism type, gripping method, gripping force, drive unit and control object characteristics, mass, shape, center of gravity position, size, dimensional tolerance, surface condition, material, strength, operating parameters, operating space environment, operating accuracy, operating speed and acceleration, clamping time.

HERZOG workholding fixture types

1) Standard rectangular electromagnetic chuck Application: Surface grinding machines with rectangular tables. 2) High-power electromagnetic chuck Application: Milling machines, planing machines, machining centers. 3) Fine-pole electromagnetic chuck Application: Surface grinding machines with rectangular tables, milling machines. 4) Multi-function high-power electromagnetic chuck Application: Surface grinding machines with rectangular tables. 5) Rotary electromagnetic chuck Application: Various surface grinding machines. 6) Electromagnetic chuck for knife grinding Application: Knife grinding machines. 7) Circular electromagnetic chuck (concentric circle type) Application: Surface grinding machines with circular tables. 8) Circular electromagnetic chuck (radial pole type) Application: Surface grinding machines with circular tables. 9) Circular electromagnetic chuck (plum blossom pole type) Application: Surface grinding machines with circular tables. An electromagnetic chuck is an electromagnetic fixture that secures the workpiece being processed by the suction force generated by the chuck body after the electromagnetic coil is energized. The electromagnetic chuck consists of several parts, including an iron core, coil, faceplate, and bracket. The electromagnet, composed of the coil and iron core, is the main part of the electromagnetic chuck.

HERZOG 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 rotary 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.

HERZOG 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 tapered pin wear exceeds tolerance, they 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 synchronous fixtures; incorrect lubrication will lead to reduced clamping force, poor precision, wear, and jamming, so correct lubrication is essential. After processing, 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 anti-rust cutting oil. Remove the synchronous fixture every six months for a thorough cleaning (every two months at least when machining cast iron or copper products). Check parts for damage or wear, and replace with new items immediately if severe. Lubricate thoroughly before assembly.
