Description
One, technical field
The utility model relates to a kind of metal cutting process equipment, and is a kind of specifically double support planer bed.
Two, background technology
Planer is a kind of common metal cutting process equipment, is divided into two kinds of metal-planing machine and shaping machines usually.Wherein metal-planing machine is mainly used in the planing operation of heavy parts, and shaping machine is used for the planing operation of middle-size and small-size part more.Because the shaping machine volume is little, price is low, so application surface is comparatively extensive.Existing shaping machine version is the top that planer head is arranged on ram, ram is installed in the cantilever support mode and is reciprocatingly slided, and the shortcoming that this cantilever support mode is brought is exactly that supporting rigidity is relatively poor, and vibration is bigger during planing, thereby machining accuracy is lower, and ram weares and teares easily.When machinery or fluid pressure drive device promoted ram and move to range by original position, ram was increased progressively by the influence of planer head gravity or cutting force gradually, and the amount of deflection at planer head place also constantly increases.And owing to have the gap between ram and the guide rail, under the gravity effect, also there is the trend that presses down in the ram front end, and has more aggravated planer head displacement in vertical direction; When arriving range, planer head reaches maximum in the skew of this position, in this motion process, the running orbit of cutter in the space that is installed on the planer head is not straight line, but curve of bending gradually, so just cause the mismachining tolerance of part bigger, and this situation with the length of cantilever also be the lengthening of ram stroke and more serious, this has just limited the axial length of institute's processing parts.Because ram adopts cantilever design,, guide rail also can reduce processing precision of products greatly again even producing a spot of wearing and tearing.In addition, in order to support the planer head that overhangs, the bed ways face must be made longlyer, has so also increased Master Cost and manufacturing cost.
