Description
Technical field
The present invention relates to machine tool field, especially engine lathe, numerically controlled lathe, turning center.
Background technology
Along with developing rapidly of Digit Control Machine Tool, working shaft-like part on numerically controlled lathe, especially turning center, can complete slightly, finish turning and brill, milling, the multiple working procedure such as to attack by clamped one time completely, but, the mode that the method for clamping of current axial workpiece mainly adopts one end chuck, one end top, this mode has two kinds of processing technologys: one is that workpiece is reserved technique chuck in one end of chuck-end, and a folder one jacking row processing, excises technique chuck after processing to be done again; Two is that centre bore is got respectively in workpiece two ends, one folder one jacking row processing, to be processed complete one end after, then tune processing the other end.These two kinds of processing technologys all have drawback: the former takes material and takes a lot of work; The latter loses time, lose element precision.
Summary of the invention
In order to overcome the drawback that Machining of Shaft-type Parts technique exists, the invention provides a kind of blocking shaft type lathe, this lathe has double card, Double Tops function, toply carry workpiece all the time, by the automatic switchover of one or many to axial workpiece left end, right-hand member method of clamping, thus change the original processing technology of axial workpiece.
The technical scheme that the present invention takes is: A main shaft and B main shaft coaxial and staggered relatively, A main shaft, the telescopic chuck of A and the telescopic chuck of B B main shaft be equipped with respectively, the telescopic chuck of A, the center of the telescopic chuck of B is equipped with that A is top and B is top respectively, top and the B of A is top is also coaxial and staggered relatively, the telescopic chuck of A, the front end of the telescopic chuck of B is respectively equipped with A chuck jaw and B chuck jaw, the telescopic chuck of A, the rear end of the telescopic chuck of B is connected with B pull bar with A pull bar respectively, A pull bar, the other end of B pull bar connects with A chuck power source and B chuck power source again respectively, in the course of the work, A is top and B is top withstands in the two ends centre bore of workpiece respectively, all the time carry workpiece, when the telescopic chuck of A protract, A chuck jaw clamping workpiece, and when B chuck jaw unclamps workpiece, B telescopic chuck retrude, cutter just can processing work near one end of the telescopic chuck of B, as shown in Figure 1, when A chuck jaw unclamp workpiece, A telescopic chuck retrude and the telescopic chuck of B protracts, B chuck jaw clamping workpiece time, cutter just can processing work near one end of the telescopic chuck of A, as shown in Figure 2, by the automatic switchover of one or many to workpiece left end, right-hand member method of clamping, just can implement thick, finish turning to workpiece in the clear, and brill, milling, the processing of multiple working procedure such as attack.
The invention has the beneficial effects as follows, by changing the original processing technology of axial workpiece, shortening process time, decreasing the waste of material, improve the precision stability of part.
