Beam CNC gantry machine tool slide guide rail unloading device

The CNC gantry machine tool bar slide in 2018 - with guide rail unloading equipment 08 - 06 with the development of the mechanical processing technology and the need of mechanical processing industry, can undertake large workpiece machining of large gantry machine tool arises at the historic moment, in order to meet the processing of high power high torque requirements, mainstream beams stepped rectangular guide into a large gantry machine tool design, is widely used. Machine tools in order to ensure the machining accuracy, greatly strengthen the rigidity, the framework of the transverse sliding plate and the significant increase in the weight of ram to milling head, resulting in a series of problems: a, horizontal slip board and ram milling head all of the weight of load on the beam reference guide, has greatly increased the benchmark beam on the surface of the guide rail support load, easy to cause deformation of guide rail. Second, with the operation of the machine tool, reference guide in beams under the condition of bearing surface under enormous pressure, between the beam and lateral slip board strip wear, serious impact on the accuracy of machine tools. , benchmark beam guide bearing surface and horizontal slip plate between the pressure and friction increase, lateral slide carriage drive motor required torque increase, caused the additional load of machine tool, affect the operation of the machine tool. Guide rail unloading device in the diagram, T 2 set fixed on the horizontal slip board, the key points in a complete set of institutions, nut 1 by threaded connection on the T set of 2, 5 and lateral slip bearing support plate hole clearance fit, the guiding role, 8 by spherical roller bearing shaft fixed on the bearing support 5, 6 to 7 8 positioning spherical roller bearing, axis 3 axis by 4 fixed on the bearing support 5, general use saucer spring leaf 10 installation between the nut and bearing support 5 1, two sets of same organisations through 11 key position, to prevent deflection, by rotating nut 1 adjusting general use saucer spring leaf 10 the amount of compression, the size of the change of pressure, pressure eventually passed on the steel band 9, realize the unloading. Horizontal slip board flat open 75 & deg; Oblique hole through the threaded connection of fixed nut 1; Beam processing & 15 deg. Oblique guide rail, quenching 65 mn steel band 9; Slip plate oblique hole 5 bearing holder setup, the guiding role, the bottom through a pin shaft equipped with 8 spherical roller bearing, rolling on the beam steel band 9; Top with a fixed nut 1 piece of 10 install there are general purpose between disc springs, adjustable pressure; The slip plate were equipped with four groups of institutions, through 11 key connection, ensure the direction of the organization and spherical roller bearing eight line contact with the beam steel band 9. A complete set of institutions to install on the horizontal slip board, through the key position, install a saucer spring piece, middle pressure adjustable, contact with the beam steel strip for the rolling bearing. Institutions through the horizontal slip plate hole of a complete set of installation, the same device with long key tandem fixed position, between the nut and bearing bracket installation general use saucer spring piece, may be changed by adjusting the nut pressure, body finally to bearing contact beam steel strip rolling line contact way. （ Mechanical commune circle)
