German och workholding fixtures och model och price

och 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 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, 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, size, dimensional tolerance, surface condition, material, strength, operating parameters, operating space environment, operating accuracy, operating speed and acceleration, clamping time.

och workholding 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 a 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. Additionally, it should ensure that the geometric deviation of the workpiece's holding posture remains within the specified tolerance band.

och workholding fixture applications

Fixtures are process devices used to quickly secure workpieces during machining, maintaining the correct relative positions between the machine tool, cutting tool, and workpiece. In other words, Workholding tooling fixtures are indispensable components in mechanical machining. Driven by the development of machine tool technology towards high speed, high efficiency, precision, composite processing, intelligence, and environmental protection, fixture technology is evolving towards high precision, high efficiency, modularity, combinability, universality, and cost-effectiveness. Fixtures are also known as clamps. Broadly speaking, any device used to quickly, conveniently, and safely install workpieces in any process step can be called a fixture. Examples include welding fixtures, inspection fixtures, assembly fixtures, and machine tool fixtures. Among these, machine tool fixtures are the most common and are often simply referred to as fixtures. When machining workpieces on a machine tool, to ensure that the workpiece surface meets the technical requirements specified in the drawings, such as dimensions, geometric shapes, and mutual positional accuracy with other surfaces, the workpiece must be properly positioned (located) and securely clamped (clamped) before machining. The application of machine tool fixtures helps ensure machining accuracy and stabilize product quality; improves labor productivity and reduces costs; improves working conditions for workers and ensures safe production; and expands the process range of machine tools, achieving "multi-purpose use of one machine." Fixtures typically consist of locating elements (to determine the correct position of the workpiece in the fixture), clamping devices, tool-setting guide elements (to determine the relative position of the tool and workpiece or guide the tool direction), indexing devices (to allow the workpiece to complete machining at several stations in one installation, including rotary indexing devices and linear motion indexing devices), connecting elements, and the fixture body (fixture base). Fixtures are also extensively used by electronics manufacturers. To improve production efficiency and product quality, tooling fixtures are commonly used in the middle and later stages of production for functional testing or auxiliary assembly (to assemble fixed shapes and heights, etc.). Their actual applications in electronic manufacturing plants are very broad; since they are non-standard custom-made products, the only limit is imagination.

och workholding fixture maintenance

When using vacuum suction cups (without clamps), note that the manipulator's movement speed should not be too high; otherwise, shear forces will be generated on the suction cup, causing the product to easily drop during rapid twisting. In some cases, a clamp can be used to ensure safe transport of the product. Considering the possibility of the product sticking to the mold, a pneumatic clamp is usually installed to solve this problem. When the product's surface area is too small or the product is too heavy to use a vacuum suction cup, this issue can also be resolved by using a clamp. If the product has strict appearance requirements, the clamped area must not be the outer surface. To address this, a sensor circuit can be installed. After confirming that the clamp or suction cup has securely grasped 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 molding area, a special cylinder capable of independent movement without relying on manipulator operation can be added to improve this situation.
