German System 3R workpiece fixture System 3R model System 3R price

System 3R workpiece fixture is 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. In addition, 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. Usually, to avoid scratching the surface of the product, it is best to choose bellows-type suction cups 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.

System 3R workpiece fixture classification

1) Lathe fixtures: Fixtures used on lathes to machine the internal and external rotary surfaces and end faces of workpieces are called lathe fixtures. Most lathe fixtures are mounted on the spindle, while a minority are mounted on the saddle or bed. 2) Coordinate measuring machine (CMM) fixtures: Used on measuring machines, utilizing modular support and reference devices to achieve flexible fixation of the measured workpiece. This device allows for automatic programming to support the workpiece and can establish an infinite number of workpiece configuration reference points. Advanced specialized software can directly generate the workpiece clamping program within seconds based on the geometric data of the workpiece. 3) Industrial robot fixtures: All mounted on industrial robots for use in industrial automation equipment, representing one of the new technologies in modern industrial automation. They mainly appear in modern industrial production in coordination with robots, with common applications including machine tool loading/unloading, workpiece palletizing/depalletizing, welding, and grinding in automated unmanned factories. 4) Milling machine fixtures: All mounted on the milling machine table, moving with the table during feed motion. They mainly consist of positioning devices, clamping devices, fixture bodies, connecting elements, and tool-setting elements. During milling, the cutting force is large and the cutting is intermittent, resulting in significant vibration. Therefore, milling machine fixtures require high clamping force, as well as high rigidity and strength. 5) Bearing housing fixtures: To ensure and improve the production quality of bearing housings, in addition to using machine tools and other mechanical equipment, a large amount of process equipment is used, including bearing housing fixtures, molds, cutting tools, and related auxiliary tools. A bearing housing fixture is a production tool specifically designed to ensure the product quality of bearing housings, making the production process more convenient. Different bearing housing fixtures vary in structure, form, operating conditions, and design principles, resulting in a wide variety of types and styles, accounting for a significant proportion in both quantity and variety. This type of bearing housing fixture can accurately determine the relative position between the workpiece and the tool, i.e., it can clamp the workpiece to be machined, thereby completing the motions required during the machining process. Since bearing housing fixtures play a very important role in the bearing housing production process, the drafting of their design drawings is also crucial.

System 3R workpiece fixture features

1) Standardization: Standardization and generalization of machine tool fixtures are two interrelated aspects. China already has national standards for fixture parts and components: GB/T2148~T2259－91, as well as standards for various general-purpose fixtures and modular fixtures. Standardization of machine tool fixtures facilitates commercial production of fixtures, helps shorten production preparation cycles, and reduces total production costs. 2) Precision: As the precision of mechanical products continues to improve, the precision requirements for fixtures inevitably increase. There are many structural types of precision fixtures, such as multi-tooth discs for precision indexing, with an indexing accuracy of up to ±0.1"; and high-precision three-jaw self-centering chucks for precision turning, with a centering accuracy of 5μm. 3) High efficiency: High-efficiency fixtures are mainly used to reduce the basic and auxiliary time of workpiece machining, thereby improving labor productivity and reducing workers' labor intensity. Common high-efficiency fixtures include automated fixtures, high-speed fixtures, and fixtures with clamping force devices. For example, using an electric vise to clamp workpieces on a milling machine can improve efficiency by approximately 5 times; using a high-speed three-jaw self-centering chuck on a lathe ensures that the jaws can still firmly clamp the workpiece at a test speed of 9000r/min, thereby significantly increasing the cutting speed. In addition to configuring corresponding high-efficiency and automated fixtures in production lines and automatic lines, various automatic workpiece clamping fixtures and automatic fixture changing devices have appeared on CNC machine tools, especially machining centers, fully leveraging the efficiency of CNC machine tools. 4) Flexibility: The flexibility of machine tool fixtures is similar to that of machine tools, referring to the ability of machine tool fixtures to adapt to variable process factors through adjustment, combination, and other methods. The main variable process factors include operation characteristics, production batch size, and the shape and dimensions of the workpiece. New types of fixtures with flexibility characteristics mainly include: modular fixtures, general-purpose adjustable fixtures, group fixtures, modular fixtures, and CNC fixtures. To meet the needs of modern mechanical industry for multi-variety, small-to-medium batch production, expanding the degree of flexibility of fixtures, changing the non-detachable structure of special-purpose fixtures to a detachable structure, and developing adjustable fixture structures will be the main direction of current fixture development.

System 3R workpiece fixture maintenance

1) Before use, check 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, 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 jamming, so correct lubrication is essential. After machining, be sure to clean the body and slide ways of the synchronous fixture with an air gun or similar tool. When 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 accumulated chips inside the fixture. To avoid reduced clamping force due to rust, use rust-preventive cutting oil. Remove the synchronous fixture every six months for 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.
