German schlenker workpiece fixtures schlenker model schlenker price

schlenker workpiece fixtures refer to devices used in the mechanical manufacturing process to secure the workpiece, ensuring it occupies the correct position for machining or inspection; they are also known as jigs. In a broad sense, any device used to quickly, conveniently, and safely install a workpiece during any operation in the process can be called a fixture. 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 (enabling the workpiece to complete machining at several stations in a single setup, including rotary indexing devices and linear indexing devices), connecting elements, and fixture bodies (fixture bases). Examples include welding fixtures, inspection fixtures, assembly fixtures, and machine tool fixtures, among which machine tool fixtures are the most common and are often simply referred to as fixtures. When machining a workpiece on a machine tool, to ensure the surface meets the technical requirements specified in the drawing, such as dimensions, geometric shape, and mutual positional accuracy with other surfaces, the workpiece must be properly located (positioning) and securely clamped (clamping) before machining.

schlenker workpiece fixture requirements

Whether clamping or suction-based, the robot's end-effector must have the repeatability required for the task. The structure of the robot end-effector should be as simple and compact as possible, with light weight, to reduce the load on the arm. Dedicated robot end-effectors have a simpler structure than general-purpose ones, offer high work efficiency, and can perform various tasks. In contrast, "universal" end-effectors may have disadvantages such as complex structures and high costs. Therefore, it is recommended to design and use serialized, standardized, dedicated robot end-effectors that can be quickly changed. If an object has two opposing flat surfaces, a parallel double-jaw gripper can be used to address dimensional deviation issues. For cylindrical objects, double-jaw grippers can also be used for clamping. Note that retaining or encompassing clamping requires less force.

1) General-purpose fixtures: General-purpose fixtures are standardized fixtures that can be used to machine different workpieces within a certain range. Examples include three-jaw chucks and four-jaw independent chucks on lathes, and vise jaws, indexing heads, and rotary tables on milling machines. These fixtures are generally produced by specialized factories and are often supplied to users as machine tool accessories. They are characterized by wide adaptability and low production efficiency, making them mainly suitable for single-piece and small-batch production. 2) Dedicated fixtures: Dedicated fixtures are designed specifically for a particular operation on a specific workpiece. They are characterized by compact structure, rapid, convenient, and labor-saving operation, and can ensure high machining precision and production efficiency. However, the design and manufacturing cycle is long, and manufacturing costs are high. When the product changes, the fixture becomes unusable and is scrapped. They are only suitable for production with fixed products and large batches. 3) Universal adjustable fixtures and group fixtures: Their characteristic is that some components of the fixture can be replaced and some devices adjusted to accommodate the machining of different parts. Fixtures used for group machining of similar parts are called group fixtures. Compared with group fixtures, universal adjustable fixtures have less clearly defined machining objects and a wider scope of application. 4) Modular fixtures: Modular fixtures are assembled from a set of pre-manufactured standard components and parts according to the machining requirements of the part. Manufactured by professional manufacturers, they are characterized by flexibility, strong versatility, short manufacturing cycles, and reusable components, making them particularly suitable for new product prototyping and single-piece small-batch production. 5) Pallet fixtures: Pallet fixtures are used in automated lines. This type of fixture not only serves to clamp the workpiece but also moves as one unit with the workpiece along the automated line from one station to the next for different machining operations.

Mechanical clamping end-effectors used in loading and unloading industrial robots are mostly two-finger grippers. Classified by finger motion, they can be divided into translational and rotary types. Classified by mechanical clamping method, they can be divided into external clamping and internal expanding types. Classified by mechanical structural characteristics, they can be divided into electric (electromagnetic), hydraulic, and pneumatic types, as well as combinations thereof. 1) Pneumatic suction type: Pneumatic suction robot end-effectors use the suction force generated by negative pressure inside the suction cup to hold and move the workpiece. The suction cup creates negative pressure in a soft rubber or plastic bellows to hold the workpiece. This type of robot end-effector is suitable for handling large, thin, low-rigidity metal or wooden sheets, paper, glass, and curved shells. Depending on the application, the end-effector can be made with single, double, multiple, or specially shaped suction cups. Methods for generating negative pressure include: squeeze-type suction cups, airflow negative pressure suction cups, and vacuum pump exhaust suction cups. Squeeze-type suction cups: Squeeze-exhaust suction cups expel all air from the cup by downward squeezing force, creating a negative pressure state inside to hold the workpiece. Advantages include simple structure, light weight, and low cost. However, the suction force is not large, so they are mostly used for workpieces that are not too large in size, thin, and light. Airflow negative pressure suction cups: An airflow control valve injects compressed air from an air pump through a nozzle, forming a high-speed jet that removes air from the suction cup cavity, creating negative pressure to hold the object. This type is convenient and low-cost if compressed air is available at the job site. Vacuum pump exhaust suction cups: Vacuum pump exhaust suction cups connect the vacuum pump to the suction cup via an electromagnetic control valve. When the control valve evacuates air, negative pressure forms in the cup cavity to hold the object. Conversely, when the control valve connects the suction cup to the atmosphere, the suction cup loses suction and releases the workpiece. The suction force of vacuum pump suction cups mainly depends on the suction area and the vacuum degree inside the q cavity (referring to the rarefaction of air inside). This type of suction cup works reliably and provides greater suction force, but requires a vacuum pump and airflow control system, resulting in higher costs. 2) Mechanical clamping type: The structure of a straight-rod dual-cylinder translational gripper refers to gripper fingers mounted on a straight rod with finger mounting seats. When pressurized gas enters the rod-side chambers of the two single-acting dual cylinders, the two pistons move toward the center, clamping the workpiece; when no pressurized gas enters, springs push the two pistons outward, releasing the workpiece. A flow divider valve is installed in the cylinder intake line to ensure synchronous movement of the two pistons. This type of end-effector is used in loading and unloading assembly workstations.
