heinrich betz workholding fixtures are devices that hold objects for manipulation. They can grip and release objects while performing certain actions. Motion devices often mimic human movement; in the case of grippers, they mimic finger movement. The "fingers" themselves are not part of the gripper; they are specialized custom tools for holding objects, called "jaws." Two main gripping actions: External gripping: This is the most common method for holding objects. It is the simplest and requires the shortest stroke length. When the gripper jaws close, the clamping force applied by the gripper holds the object. Internal gripping: In some applications, due to the geometry of the object or the need to access the exterior of the object, it is necessary to grip the object from the center. In this case, the gripper holds the object through expansion force.

heinrich betz workholding 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 type 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 clamp cylinders and lever arm cylinders apply clamping force to 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.

Fixtures are process devices used to quickly secure workpieces during machining, maintaining the correct relative positions of 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, complexity, intelligence, and environmental friendliness, fixture technology is moving towards high precision, high efficiency, modularity, combinability, universality, and cost-effectiveness. Fixtures are also known as jigs. 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 machine tools, to ensure that the surface of the workpiece meets technical requirements such as dimensions, geometric shape, and mutual positional accuracy with other surfaces as specified in the drawings, the workpiece must be properly positioned (location) and securely clamped (clamping) before machining. The application of machine tool fixtures helps ensure machining accuracy and stabilize product quality; helps improve labor productivity and reduce costs; helps improve working conditions and ensure safe production; and helps expand 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 widely used in 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 (capable of assembling fixed shapes and heights, etc.). Their actual use in electronic manufacturing plants is very extensive. Since they are non-standard custom-made, the possibilities are limited only by imagination.

heinrich betz workholding fixture maintenance

1) Before use, check whether the limit dimensions are still in the correct position. 2) If the stop pins are worn beyond tolerance, they can be polished and repaired; if the baffles, pins, or locating taper pins are worn beyond tolerance, they 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 synchronous fixtures. Incorrect lubrication will lead to reduced clamping force, poor precision, wear, and seizing, so proper 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 their 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 for a thorough cleaning every six months (at least every two months when machining cast iron or copper products). Check parts for damage or wear, and replace with new parts immediately if severe. Lubricate thoroughly before assembly.
