German ridge workholding fixtures ridge model ridge price

ridge workholding fixtures are any tools connected to the robot edge (joint) with specific functions. This may include robot grippers, robot tool changers, robot collision sensors, robot rotary connectors, 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). Key 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.

ridge workholding fixture requirements

Whether clamping or suction-type, the robot end-effector must also meet the repeatability accuracy required for the task. The structure of the robot end-effector should be as simple and compact as possible, and lightweight, to reduce the load on the arm. Dedicated rather than general-purpose robot end-effectors have a simpler structure but high work efficiency, and can perform various tasks. In contrast, "universal" end-effectors may have disadvantages such as complex structure and high cost. Therefore, it is recommended to design and use serialized and standardized dedicated robot end-effectors that can be quickly changed. If the object has two opposing flat surfaces, a double-jaw parallel gripper can be used to solve dimensional deviation problems. For cylindrical objects, double-jaw grippers can also be used for clamping. Note that retaining or enveloping clamping requires less force.

ridge 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.

ridge 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 locating tapered 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 maintains 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 items immediately if severe. Lubricate thoroughly before assembly.
