heinrich betz workholding fixtures are devices that hold objects to manipulate them. They can grip and release objects while performing certain actions. Motion devices often mimic human movements; in the case of grippers, they mimic finger movements. 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 fixture or a complex integrated production line, the design process for hydraulic fixtures is the same, proceeding in the following order: formulation of the overall scheme, selection of hydraulic cylinder types and specifications, selection of control valves, design of mechanical parts, selection of pump station accessories, and system connection. Hydraulic fixtures provide powerful clamping and positioning forces for various machining processes. Yunpower cylinders are used for positioning and clamping in automated machining processes. Products such as self-centering vises and self-centering clamping elements provide good positioning, swing clamp cylinders and lever cylinders provide clamping force on products, and support cylinders prevent deformation during product machining. From simple fixturing to robot-assisted machining centers, cylinders provide clamping and support forces to improve production efficiency.

A fixture is a process device used to rapidly secure the workpiece during machining, maintaining the correct relative positions of the machine tool, cutting tool, and workpiece. In other words, Workholding fixtures are indispensable components in mechanical machining. Driven by the development of machine tool technology toward high speed, high efficiency, high precision, integration, intelligence, and environmental friendliness, fixture technology is evolving toward high precision, high efficiency, modularity, combinability, universality, and cost-effectiveness. Fixtures are also known as clamping devices. Broadly speaking, any device used to rapidly, conveniently, and safely mount a workpiece during any operation in the manufacturing process 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 referred to simply as fixtures. When machining a workpiece on a machine tool, the workpiece must be properly located (positioning) and firmly held (clamping) before machining to ensure that its surface meets the technical requirements specified in the drawing, such as dimensions, geometric shape, and mutual positional accuracy with other surfaces. The use of machine tool fixtures helps ensure machining accuracy and stabilize product quality; improves labor productivity and reduces costs; improves working conditions and ensures safe production; and expands the technological capabilities of machine tools, enabling "one machine, multiple uses." A fixture typically consists of locating elements (to determine the correct position of the workpiece within the fixture), clamping devices, tool-setting or guiding elements (to determine the relative position between the cutting tool and the workpiece or to guide the tool direction), indexing devices (to allow the workpiece to undergo machining at several stations in a single setup, including rotary indexing devices and linear indexing devices), connecting elements, and the fixture body (fixture base). Fixtures are also widely used in electronics manufacturing. To improve production efficiency and product quality, fixtures are commonly used in the middle and later stages of production for functional testing or auxiliary assembly (to achieve fixed shapes, heights, etc.). Their applications in electronic manufacturing plants are extremely broad; since they are often custom-made non-standard items, the possibilities are virtually limitless.

heinrich betz 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 taper 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 synchronous fixtures; incorrect lubrication will lead to reduced clamping force, poor precision, 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 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 every six months for a thorough cleaning (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.
