German wbu workholding fixtures wbu model wbu price

wbu workholding fixtures refer to devices used in the manufacturing process to secure the workpiece in the correct position for machining or inspection, also known as jigs. In a broad sense, any device used to quickly, conveniently, and safely install workpieces during any step of 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 (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 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 workpieces on machine tools, to ensure that the surface of the workpiece 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 located (positioning) and securely clamped (clamping) before machining.

wbu workholding fixture classification

Due to the different operating characteristics and structural forms of various machine tools, different requirements are correspondingly imposed on the structure of the fixtures used. According to the machine tools used, fixtures can be divided into: lathe fixtures, milling machine fixtures, drilling machine fixtures, boring machine fixtures, grinding machine fixtures, gear machine tool fixtures, and other machine tool fixtures. According to the clamping power source adopted by the fixture, they can be divided into: manual fixtures, pneumatic fixtures, hydraulic fixtures, pneumatic-hydraulic fixtures, electric fixtures, magnetic fixtures, and vacuum fixtures. Specialized classifications include general-purpose fixtures, special-purpose fixtures, general-purpose adjustable fixtures, group fixtures, modular fixtures, and pallet fixtures. A pallet fixture is a type of fixture used on automated lines. This fixture not only serves to clamp the workpiece but also becomes integrated with the workpiece, moving from one station to the next along the automated line for different machining operations.

wbu workholding fixture operation

1) Assemble the two engine bushings onto the 1 strut according to the "Strut Welding Assembly" drawing, and place them on the fixture body, position the 1 strut using stop pins and stop plates, clamp the 1 strut with a spiral clamp; simultaneously position the two 4 engine bushings with pins, and clamp them with quick-release spiral clamping devices; 2) After tack welding, release the quick-release spiral clamping devices, remove the pins, take off for welding; 3) Place the welded assembly back on the fixture body, position the welded assembly using stop pins and stop plates, clamp the welded assembly with a spiral clamp; then place the assembly of the M6 nut and horn bracket onto the welded assembly, position it using the conical pins on the spiral clamping mechanism and the grooves in the pressure plate of the spiral clamping mechanism, and clamp it with the spiral clamping mechanism; 4) Perform three-sided welding on the assembly of the M6 nut and horn bracket and the strut, then release all spiral clamps, the pressure plate of the spiral clamping mechanism clamping the M6 nut and horn bracket assembly is spring-loaded upward, the positioning conical pins on it disengage from the welded assembly, then push out the pressure plate to disengage one end from the spiral clamping mechanism stud, rotate the pressure plate to the side of the welded assembly, then remove the welded assembly.

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 workpieces. The suction cup creates negative pressure in a bellows made of soft rubber or plastic 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 designed 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 suction cup by downward squeezing force, creating a negative pressure state inside to hold the workpiece. They have advantages such as simple structure, light weight, and low cost. However, the suction force is not large, so they are mostly used for workpieces with small dimensions, thin and light. Airflow negative pressure suction cups: An airflow control valve injects compressed air from an air pump into a nozzle, forming a high-speed jet that removes air from the suction cup cavity, creating negative pressure to hold the object. If compressed air is available at the job site, using this type of suction cup is convenient and low-cost. 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, the air in the suction cup cavity is removed, creating negative pressure 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 adsorption area of the suction cup and the vacuum degree inside the q cavity (referring to the thinness of the air inside). This type of suction cup is reliable and has strong suction, but requires a vacuum pump and airflow control system, resulting in higher costs. 2) Mechanical clamping type: The structure of a straight-bar dual-cylinder translational gripper refers to the gripper fingers installed on a straight bar equipped 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. To ensure synchronous movement of the two pistons, a flow divider valve is installed on the cylinder intake path. This type of end-effector is used in loading and unloading assembly workstations.
