Description
Technical field
This utility model relates to a kind of automated machine tool accessory, specifically one side's ram little automatic right-angle head.
Background technology
Automatic right-angle head be a kind of use be also at most simultaneously the maximum automated machine tool aftermarket product of the market share.Along with automatic right-angle head progressively to high speed, miniaturization, occur in that some little automatic right-angle heads.CN 203254211U discloses the High-Speed Automatic right-angle head of a kind of compact structure, including casing, main shaft and the drive mechanism being arranged between casing and main shaft, casing is made up of upper box and lower box, and upper box is provided with multiple blind rivet, and upper box is connected with pull head oil cylinder by multiple blind rivets；Drive mechanism includes the first gear drive, power transmission shaft and the second gear drive, first gear drive is arranged on one end of power transmission shaft, second gear drive is arranged on the other end of power transmission shaft, and second gear drive be connected with main shaft, power transmission shaft is arranged in transmission shafts bearing, is provided with back-to-back first angular contact ball bearing between transmission shafts bearing and power transmission shaft；Upper box is set in the upper end of transmission shafts bearing, and lower box is set in the lower end of transmission shafts bearing；The rotating speed of this automatic right-angle head, up to 4000rpm, meets mould processing request.Compared with the automatic right-angle head of stock size, with the obvious advantage in terms of Z axis processing stroke.Therefore this utility model automatic right-angle header structure is compact, and rotating speed is high, and the cost performance making pentahedron lathe is higher.Although this automatic right-angle grease head highness direction size is less, Z axis processing stroke in terms of with the obvious advantage, but this automatic right-angle head still suffers from the nibs in the design of some structures, there is the space of improvement, it is mainly reflected in: first, this automatic right-angle head is primarily adapted for use in the T-shaped ram of 350 side's rams or same specification, it is impossible to be applied to other specifications such as 400 or 450 side's ram；Secondly, the processing complicated, difficult of transmission shafts holder structure, and owing to structure limits, the top cylinder wall thickness of the transmission shafts bearing being connected with lower chain wheel is relatively thin, and structure is weaker herein；Adjustment pad between transmission shafts bearing and lower box can be used for adjusting bevel gear gap, and this washer diameter is big, and match grinding is inconvenient；Additionally, the rear end of the main spindle front bearing seat of this automatic right-angle head is without dustproof construction, the protection to main spindle front bearing (i.e. the third angle contact ball bearing) is not good enough.The application is the improvement on the basis of CN 203254211U.
