German nubius workpiece fixtures, nubius models, nubius prices

nubius workpiece fixtures are devices used in the manufacturing process to secure the workpiece in the correct position for machining or inspection, also known as jigs. Broadly speaking, any device used to quickly, conveniently, and safely install a workpiece 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 within 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 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, with machine tool fixtures being the most common, often simply referred to as fixtures. When machining a workpiece on a machine tool, to ensure that 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 and securely clamped before machining.

nubius Workpiece Fixture Classification

1) Lathe fixtures: Fixtures used on lathes to machine internal and external rotational 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, these utilize modular support and reference devices to achieve flexible fixation of the measured workpiece. This device allows automatic programming to support the workpiece and can establish an unlimited number of workpiece configuration reference points. Advanced dedicated software can directly generate the workpiece clamping program within seconds using the workpiece's geometric data. 3) Industrial robot fixtures: Mounted on industrial robots for use in industrial automation equipment, representing one of the newer technologies in modern industrial automation. They primarily appear in modern industrial production in conjunction with robots, with common applications in automated unmanned factories for machine loading/unloading, workpiece palletizing/depalletizing, welding, grinding, etc. 4) Milling machine fixtures: Mounted on the milling machine table, moving with the table during feed motion. They mainly consist of locating devices, clamping devices, fixture bodies, connecting elements, and tool-setting elements. During milling, cutting forces are high and cutting is intermittent, causing significant vibration; therefore, milling 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 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 specialized production tool 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, which account for a significant proportion in both quantity and diversity. This type of fixture can accurately determine the relative position between the workpiece and the tool, meaning it can clamp the workpiece to be machined, thereby enabling the necessary movements during the machining process. Since bearing housing fixtures play a crucial role in the production process, drawing their design diagrams is also very important.

nubius Workpiece Fixture Operation

1) Assemble 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 part back on the fixture body, position the welded part using stop pins and stop plates, clamp the welded part with a spiral clamp; then place the assembly of the M6 nut and horn support on top of the welded part, position it using the conical head pin on the spiral clamping mechanism and the groove opened on 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 support and the strut, then release all spiral clamps, the pressure plate of the spiral clamping mechanism clamping the M6 nut and horn support assembly is lifted by springs, the positioning conical head pin on it disengages from the welded part accordingly, then push out the pressure plate so that one end disengages from the spiral clamping mechanism stud, rotate the pressure plate to the side of the welded part, then remove the welded part.

nubius Workpiece Fixture Usage

With the continuous development of China's industry, the use of electromagnetic chucks in industrial production is becoming increasingly widespread, the most important aspect of an electromagnetic chuck is to look at its parameters, Among the performance parameters of electromagnetic chucks, the most important are the lifting capacity and its duty class. The so-called lifting capacity of an electromagnetic chuck refers to, under specified operating conditions, the maximum weight of the load allowed to be lifted, or in other words, it is called the rated lifting capacity. For cranes equipped with electromagnetic chucks, the lifting capacity should also include the weight of the electromagnetic chuck. Rectangular electromagnetic chucks have lifting threaded holes on both sides; during installation, simply screw in T-shaped screws for lifting, and use T-shaped blocks and screws to fix it to the workbench. Connect the DC power supply and ground wire on the machine tool, then precision grind the upper surface of the chuck once to ensure the parallelism between the upper surface and the bottom surface. When holding a workpiece, as long as two adjacent magnetic poles are bridged, sufficient positioning holding force can be obtained, allowing grinding operations to proceed. Via the machine tool buttons, magnetization and demagnetization of the workpiece can be achieved. Before use, the surface of the electromagnetic chuck should be wiped clean to avoid scratches. Severe impacts are not allowed, so as not to affect accuracy. After use, wipe it clean and apply anti-rust oil to prevent corrosion. When using the electromagnetic chuck alone, a grounding wire must be provided to prevent electric shock due to leakage.
