Both the CNC special grinding machine and the universal grinding machine perform the same grinding function.
In the cylindrical grinding, it should have the function of supporting and driving the workpiece to rotate and reciprocate: it should have the function of high-speed rotation of the grinding wheel and can realize the feed displacement. This is the basic function of completing the cylindrical grinding and is a necessary condition for the existence of the product. Design these functions into workpiece headstock modules (including drive, spindle train, positioning, drive, etc.), tailstock modules, workbench modules (including drive, positioning, etc.), wheel frame modules (including drive, spindle train, positioning, protection) , drive, feed, etc.), grinding center (grinding machine for outer circle, inner circle, end face, end face outer circle) turntable module and grinding wheel dressing module. These modules are placed on a bed platform, plus some control systems and auxiliary function modules to develop a universal grinding machine. The features of these modules are:
The function independent module is independent, easy to assemble on a unified platform and with independent modules of electrical, digital display, detection, hydraulic and cooling systems, forming a variety of variants, achieving different processing precision, different working performance, different automation Machine tools of varying degrees and different processing efficiencies.
The functional parts of the basic parts refer to the large parts of the machine tool, such as the bed, the workbench, the box and the sliding seat. Most of them use castings or welded parts. The blank preparation and processing cycle are long, which affects the rapid development of the product. Therefore, the entire series of modular design is generally based on the same large-scale parts, functionalized, so that the machine can expand the working space, adapt to different machine layout, shape and protection: the machine specifications and performance in the premise of ensuring rigidity There is a possibility of change. A grinder bed module can be used to adapt to the fixing of various cabinets and slides, and it is a universal type, end-face round type, high-efficiency cut-in type or other special-purpose machine tools.
Adapting to new technology applications The application of new technologies is often aimed at improving efficiency (high speed), improving machining accuracy (nanoscale), automation (digitalization), flexibility, and networking. As long as there is a certain space in the basic component module or in the cabinet and the slide module, some modules can be added.
Socialization of functional components Under the guidance of modular thinking, various functional components, such as drive system, control system, spindle system, guide rail pair, ball screw pair, cooling system, refrigeration system, detection system, etc. are independent, standardized and professional. Manufacturing has promoted the development of modular design methods. A large number of functional modules for CNC special grinding machines are sourced from the factory's own universal grinding machine modules and commercially available functional components.
5 main design points
Work surface layout design
Special grinding machines are based on some typical parts (such as crankshafts, camshafts, air valves, left and right cranks, eccentric shafts, universal joints, gear shafts, etc.) for efficient grinding. Therefore, at the time of design, the grinding process analysis is performed on the workpiece on the platform (workbench) of the selected general grinding machine, and the corresponding dedicated part is set. These sections include:
Automatic workpiece loading and unloading is often used for workpieces with small workpiece loading and unloading. The larger workpiece is manually fed to the auxiliary bracket, and the workpiece is sent out by the flipping robot, and the workpiece is manually cut.
The support of the workpiece includes an auxiliary bracket before the workpiece is positioned and a head for positioning the workpiece, a tailstock top support, or a headstock chuck support. Configure the corresponding auxiliary functions, such as injecting the cooling fluid into the top hole to prevent thermal deformation of the bearing.
The driving and quasi-stop of the workpiece are driven by the headstock spindle dial or on the rotatable spindle chuck to drive the workpiece to rotate. For some externally shaped workpieces (crankshafts, camshafts, etc.), when the drive is stopped, it should be stopped at a good loading and unloading position, and the drive device should have a quasi-stop function.
