Description
Technical field:
The present invention relates to a kind of metal cutting process equipment, particularly a kind of portal shaped curve molding milling machine for guide face of bed body of digital control lathe is mainly used in the working face of guide rail on machining tool bed body top.
Background technology:
The bed body of lathe is one of critical component of lathe, and bed body upper surface is that the hardness of working face of guide rail is particularly important, and it directly influences the service life of lathe and the retentivity of precision.Existing machine tool bed body upper rall working face at first is to adopt vertical planer processing, carries out Quenching Treatment and grinding again.As shown in Figure 6: bed body 10 can deform when quenching, and bed body 10 upper rall working faces form one deck quench hardened case 11 after quenching, and number in the figure 12 is that bed body 10 is because the deformation curve that quenches and produced.Working face after this distortion is middle lacking of grinding when grinding, and it is many that grind at two, just occurred the middle hardness height at last, the shortcoming that two hardness is low.In order to address the above problem, before try plane is cut, when bed body 10 being fixed on the workbench 20 of vertical planer, with bolt and nut 14 and pressing plate 13 with bend in the middle of the bed body 10 (referring to Fig. 7), make the intermediate portion be bent downwardly distortion, treat to unclamp pressing plate 13 behind the adjustable cast iron planes, recover to form intermediate projections by the elasticity of bed body 10, carry out Quenching Treatment again, to offset the distortion that the back of quenching takes place.This method, because the hardness of foundry goods is different with rigidity, the structure of gusset is different with the position, the projection value alters a great deal, even same bed body, with same pressure, the maximum difference of the numerical value of projection can reach 0.6 millimeter more than, and the value of each section projection presents nonlinear state in the longitudinal direction, irregular, there is the uniformity of 20% bed body hardness to be lower than national standard, need interim the processing to use, there have the uniformity of bed body hardness after grinding of 6% to compare with GB to be widely different, must carry out secondary quenching.Be prone to a body guide rail surface scaling loss or crackle and scrap phenomenon in secondary quenching, the grinding behind the secondary quenching because the error of bed body projection is very big, time-consuming, has increased processing cost.
Summary of the invention:
The purpose of this invention is to provide and a kind ofly become the intermediate projections shape to offset the portal shaped curve molding milling machine for guide face of bed body of digital control lathe of quenching distortion, overcome the deficiencies in the prior art bed body working face of guide rail time processing.
Technical solution of the present invention is: a kind of portal shaped curve molding milling machine for guide face of bed body of digital control lathe, it comprises gantry fuselage 1, slide plate 2 is housed above gantry fuselage 1, the below of gantry fuselage 1 is provided with the travelling table 3 that joins with power set, it is characterized in that: on slide plate 2, be fixed with the gearbox 5 that joins with motor 6, the output of gearbox 5 cutting spindle 4 that is coupling, described cutting spindle 4 be arranged in parallel with the working face of travelling table 3.
One end of described cutting spindle 4 and the output shaft 7 of gearbox 5 are fixedly connected, and the other end of cutting spindle 4 is equipped with bracing frame 15, and bracing frame 15 is contained on the gearbox 5.
The side processing unit (plant) is equipped with in the both sides of described fuselage 1.
Described side processing unit (plant) structure is in the both sides of gantry fuselage 1 gearbox 16 to be housed, the input of gearbox 16 motor 18 that is coupling, the output of the gearbox 16 radial cutter mounting rod 17 that is coupling.
The present invention compared with prior art has following advantage: because cutting spindle is parallel to workbench setting, several milling cutters can be housed on this be combined into the shape that matches with desire processing bed body upper rail working face, all machined surfaces can carry out simultaneously during cutting, the machined surface of both sides also can be simultaneously processed, time saving and energy saving, save process time.Moving up and down with moving horizontally by control device of travelling table of the slide plate of gantry body upper cooperates control by motor, can guarantee that a body is processed to the low shape in middle protruding two, the degree of depth that the height of projection is set up to deform with quenching (middle recessed) adapts, cancel each other, substantially be in linearity after making distortion, again through grinding, the quench hardened case thickness uniformity of working face of guide rail.Thoroughly solved Qa problem in the prior art, reduced the stock removal of guide rail, significantly reduced the grinding expense, shortened the production cycle of bed body, also eliminated the quenching waste product, its efficient of product that the present invention produces is 4.5 times of former planing operation, has improved labor productivity, has reduced cost.
