German nubius workpiece fixtures, nubius models, nubius prices

nubius workpiece fixtures are devices used in the mechanical 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 workpieces in 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 complete machining at several stations in one 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 workpiece surface meets the technical requirements specified in the drawings, 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 rotating surfaces and end faces of workpieces are called lathe fixtures. Most lathe fixtures are mounted on the spindle, while a few are mounted on the saddle or bed. 2) Coordinate measuring machine fixtures: Used on coordinate measuring machines, utilizing modular support and reference devices to achieve flexible fixation of the measured workpiece. This device can be automatically programmed to support the workpiece and establish an unlimited number of workpiece configuration reference points. Advanced dedicated software can directly generate the workpiece clamping program within seconds based on the geometric data of the workpiece. 3) Industrial robot fixtures: 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 conjunction with robots, commonly used in automated unmanned factories for tasks such as machine tool loading and unloading, workpiece palletizing and depalletizing, welding, and grinding. 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, the cutting force is large and the cutting is intermittent, resulting in significant vibration. Therefore, milling machine fixtures require high clamping force, stiffness, 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. Bearing housing fixtures are specialized production tools 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, occupying a significant proportion in both quantity and variety. These fixtures can accurately determine the relative position of the workpiece and the tool, allowing the workpiece to be clamped to perform the necessary movements during machining. Since bearing housing fixtures play a very important role in the production process, drawing their design diagrams is also crucial.

nubius Workpiece Fixture Operation

1) Assemble two sequence engine bushings onto the sequence 1 strut according to the "Strut Welding Assembly" diagram, place them on the fixture body, locate the sequence 1 strut using stop pins and plates, and clamp the sequence 1 strut with a spiral clamp; simultaneously, locate the two sequence 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, and take off for welding; 3) Place the welded part back on the fixture body, locate it with stop pins and plates, and clamp it with a spiral clamp; then place the assembly of nut M6 and horn bracket on top of the welded part, locate it using the conical pin on the spiral clamping mechanism and the groove 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 nut M6 and horn bracket with the strut, then release all spiral clamps. The pressure plate of the spiral clamping mechanism clamping the nut M6 and horn bracket assembly is lifted by springs, causing the locating conical pin to disengage from the welded part. Push out the pressure plate so that one end disengages from the stud of the spiral clamping mechanism, rotate the pressure plate to the side of the welded part, and 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 examine its parameters. Among the performance parameters of electromagnetic chucks, the most critical are the lifting capacity and its working class. The so-called lifting capacity of an electromagnetic chuck refers to, under specified operating conditions, the maximum weight of objects 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 itself. Rectangular electromagnetic chucks have lifting screw holes on both sides. During installation, simply screw in T-shaped screws for lifting. Use T-shaped blocks and screws to secure 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 workpieces, 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 using the electromagnetic chuck, wipe the surface clean to avoid scratches. Severe impacts are not allowed. to avoid affecting accuracy. Wipe clean after use, and apply anti-rust oil to prevent corrosion. When using the electromagnetic chuck alone, a grounding wire must be connected to prevent electric shock from leakage.
