Processor base

Abstract

The invention relates to a processor base applied to the field of equipment processing of numerically controlled machine tool industry. The processor base comprises a base body. A worktable placing tank and a magazine tool placing tank are arranged on the base body. The base body comprises two end surfaces and two side surfaces. A chip removal port communicating with the worktable placing tank is formed below the base body. Each of the side surfaces comprises a vertical portion located on the lower end and an inclined portion located on the upper end. The upper end of the inclined portion inclines toward the inner part of the base body and the side surface is wavy. The two side surfaces of the base body are arranged in a structure, one ends of which are closed. At the moment, the trapezoidal structure of the base is arranged, and the side surface is of the wavy shape, so that force dispersion in machine tool operation can be realized, the axial force and the radial force are reduced greatly, the internal stress and the extruding stress are reduced, and the unloading force is extremely enhanced. Meanwhile, the rigidity, the strength and the precision of the machine tool are improved by the processor base, the vibration resistance and the heat stability of the base are enhanced, and the stress of the base is relatively balanced.

AI Technical Summary

Problems solved by technology

[0002] Due to welding, stamping, casting, and other processes, the original machine tool base will directly or indirectly generate residual internal stress, extrusion stress and shear stress, and its thermoplasticity is poor, which will cause deformation caused by uneven force on the base and affect the quality of the base. Support performance, the force will produce a corresponding cumulative error, which will affect the machining accuracy of the machine tool

At the same time, during the process of casting, rough machining, welding, scraping, grinding, assembly, debugging, inspection, etc., the surface of the base will form scratches, burrs, flashes, welds, slag, and paint, which will not only affect the The installation accuracy of the base and the main components affects the normal operation of the lathe, and also poses a certain safety hazard to the operator

The material of the original base is cast iron, the production process is complex, the processing is difficult, the density of the material is uneven, and the heavy and heavy workpiece is difficult to hoist, fix and transport

During the casting process, the surface is prone to collapse pits, and in the cross-section of the casting corresponding to the pits, there are often internal shrinkage cavities or shrinkage porosity, which has poor plasticity and low toughness

Moreover, the high temperature during the casting process and the splashing of molten iron pose a great threat to the safety of processing personnel and surrounding objects.

The cast iron base has poor vibration absorption, and small vibrations will cause deformation of the workpiece, which cannot meet the requirements of high precision. The thermal stability is poor, and it is easy to cause deformation of the bed

The base and the workbench are connected through the sliding seat, which indirectly affects the machining accuracy of the workpiece, affects the positioning accuracy and repeat positioning accuracy of the machine tool tool, the compensation is greater, and the cumulative error is more difficult to grasp

[0003] The original base is in the form of a rectangular parallelepiped, and the rear side needs to be connected with the column, which increases the weight of the rear side and causes the machine tool to skew, which poses a great safety hazard during the assembly process.

The inclination of the bed will affect the geometric accuracy such as position accuracy, shape accuracy, and positioning accuracy. The greater the change in geometric accuracy, the lower the motion accuracy

This in turn causes the offset of other components, such as gears, bolts, spindles, bearings, screw nuts, etc., causing an increase in static error

In addition, the previous tool magazines were all installed on the spindle box, which was difficult to load and unload, troublesome to align and position, the number of tool storage was small, repeated positioning was low, the work space was large, and the sensitivity of the machine tool was low.
