bosch rexroth fixture, German bosch rexroth model, bosch rexroth price

bosch rexroth fixtures are one of the actuators for vacuum equipment. Generally, using vacuum suction cups to grip products is the most economical method. Vacuum suction cups come in various types; rubber suction cups can operate at high temperatures, silicone rubber suction cups are very suitable for gripping products with rough surfaces, and polyurethane suction cups are highly durable. Additionally, in actual production, if oil resistance is required for the suction cup, materials such as polyurethane, nitrile rubber, or vinyl-containing polymers can be considered for manufacturing. Typically, to avoid scratching the product surface, it is best to choose suction cups with bellows made of nitrile rubber or silicone rubber. The suction cup material is made of nitrile rubber, which has high tensile strength, and is therefore widely used in various vacuum holding devices.

bosch rexroth fixture classification

Due to the different operating characteristics and structural forms of various machine tools, different requirements are correspondingly placed on the structure of the fixtures used. According to the machine tool 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, vacuum fixtures, etc. Specialized classification includes 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 automatic lines. This fixture not only serves to clamp the workpiece but also moves as one unit with the workpiece along the automatic line from one station to the next for processing different operations.

bosch rexroth fixture structure

The mechanical gripper-type end effectors used in loading and unloading industrial robots are mostly two-finger claw types. According to the motion of the fingers, they can be divided into translational and rotary types. According to the mechanical clamping method, they can be divided into external clamping and internal expansion types. According to the mechanical structural characteristics, they can be classified as electric (electromagnetic), hydraulic, and pneumatic types, as well as their combinations. When the end effector clamps the 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. In addition, it should ensure that the geometric deviation of the workpiece clamping posture reproduction is within the given tolerance zone.

bosch rexroth fixture applications

1) Can stably ensure the machining accuracy of the workpiece: When clamping a workpiece with a fixture, the positional accuracy of the workpiece relative to the tool and machine tool is guaranteed by the fixture, unaffected by the worker's skill level, making the machining accuracy of a batch of workpieces consistent. 2) Can reduce auxiliary time and improve labor productivity: Using fixtures to clamp workpieces is convenient and fast; workpieces do not need scribing and alignment, significantly reducing auxiliary time; after clamping in the fixture, the rigidity of the workpiece is improved, allowing for increased cutting amounts; fixtures capable of clamping multiple pieces or at multiple stations can be used, and high-efficiency clamping mechanisms can be adopted to further improve labor productivity. 3) Can expand the usage range of machine tools and achieve multi-functionality: According to the forming motion of the machining machine tool, attaching different types of fixtures can expand the original process range of the machine tool. For example, installing a boring template on the slide plate of a lathe or the worktable of a radial drilling machine allows for boring processing of box parts. 4) Ensure machining accuracy: Adopting fixture installation can accurately determine the mutual position between the workpiece and the machine tool/tool; the positional accuracy of the workpiece is guaranteed by the fixture, unaffected by the worker's skill level, resulting in high and stable machining accuracy. 5) Improve productivity and reduce costs: Clamping workpieces with fixtures allows for rapid positioning and clamping without alignment, significantly reducing auxiliary time; clamping workpieces with fixtures improves workpiece rigidity, thus allowing for increased cutting amounts; multi-piece and multi-station fixtures can be used to clamp workpieces, and high-efficiency clamping mechanisms can be adopted, all of which contribute to improving labor productivity. In addition, after adopting fixtures, product quality is stable, scrap rate decreases, workers with lower technical grades can be assigned, significantly reducing production costs. 6) Expand the process range of machine tools: Using special-purpose fixtures can change the original purpose of the machine tool and expand its usage range, achieving multi-functionality. For example, after installing boring template fixtures on lathes or radial drilling machines, boring processing of hole systems in box bodies can be performed; through special-purpose fixtures, lathes can also be converted for use as broaching machines to fully utilize the capabilities of general-purpose machine tools. 7) Reduce workers' labor intensity: Clamping workpieces with fixtures is convenient and fast; when using pneumatic, hydraulic, or other clamping devices, workers' labor intensity can be reduced.
