Description

The oblique double mainshaft digital controlled lathes of lathe bed level gauge formula

Technical field

The utility model, which is related to oblique lathe bed digital control lathe, especially one kind, to be increased the service life, reduces energy consumption, expands processing Scope, reduction use cost, clamped one time workpiece complete the processing of workpiece two ends, are difficult pollution workshop and reduce labor strength The double mainshaft digital controlled lathes of oblique lathe bed level gauge formula.

Background technology

The lathe of oblique lathe bed layout【Guide rail angle of inclination generally selects 45 °, 60 ° and 75 °】, not only can be in equal conditions Under, improve stressing conditions；But also the rigidity of lathe bed, particularly automatic tool changer by integrally closed Cross section Design, can be improved The arrangement of device is more convenient.Therefore, the lathe of oblique lathe bed layout【Either engine lathe, or numerically controlled lathe.】Extensively should For in mechanical processing industry, the multi items for accurate complicated various revolving parts to be processed.

The lathe of prior art oblique lathe bed layout, the top plane of guide rail is parallel with guide rail mounting surface, that is to say, that led Positioning basal plane at the top plane of rail and the bottom position of bed body has angle, results in the bottom base surface tool of the bed body of oblique lathe bed There is angle, cause to be restricted when processing part using the lathe of such oblique lathe bed, such as the zero of some different in nature Alternatives Part is processed, it is necessary to which multiple clamping, causes the element precision of processing low；The lathe of such oblique lathe bed layout is want turnning and milling being complex as one Body, difficulty is big, even if being reluctantly complex as a whole turnning and milling, used additional part is more, complicated；Such oblique lathe bed cloth The lathe rigidity of office is comparatively relatively low, and guide rail needs to bear saddle and knife tower assembly mounted thereto, with process time Passage, easy deformation, service life is short.

When in use, the lubricating oil that guide rail and the saddle part installed in guide rail are used directly passes through the low spot position of lathe bed Put in the water tank for flowing into and being located at below lathe bed, waste water drainage system is pumped into after being mixed with cutter cooling water in water tank.Waste water is arranged Waste liquid in liquid system also needs other oily-water seperating equipment and oil filter to carry out water-oil separating so that the use cost of enterprise Height, energy consumption is big.The general cooling water low spot by oblique lathe bed of cooling water that saddle part on guide rail is used flows automatically Portion is flowed into the water tank below in the middle part of oblique lathe bed naturally, because the cutterhead of high-speed cruising drives the high fast direction water tank of cooling water Or in high fast direction oblique lathe bed low spot so that cooling water is easy to splashing water tank, and the water of splashing water tank pollutes car quickly Between bottom plate because the water of the splashing water tank typically all contains greasy dirt, it is difficult to clean, have a strong impact on the tidiness in workshop, together When workman need to workshop carry out sewage cleaning, enhance the labor intensity of workman.

Each operation part is to realize braking by the rigidity of its motor, and with the extension of use time, the rigidity of motor is difficult to Ensure machining accuracy demand, often result in that Product Precision is low, the braking requirement required for instruction can not be ensured, static rigidity is poor； Once；There is static rigidity reduction in motor, whole corresponding operation part replacement will virtually be improved into the use of enterprise Cost.

When processing workpiece, can only clamped one time process one end of part, while the bearing in spindle assemblies is easily damaged, Water proofing property is poor.

Make a general survey of whole machine industry, it is impossible to level gauge is applied to the layout that lathe is carried out on oblique lathe bed, to optimize lathe Layout, this is also the technical bottleneck of industry.
