Positioning taper hole on the conelet apical axis of lower end, the conelet apical axis and pedestal horizontal plane cooperates, and bottom passes through locking screw
Mother fastens, and is provided with two orthogonal V-grooves on the table top；Positioning device includes positioning pin, stifled platform and spring, positioning pin
Through-hole on pedestal is simultaneously inserted into the location hole of index table bottom, and spring pocket is limited on positioning pin and using stifled platform
Position；Pressing device includes pressing plate, parallels, nut and screw rod, and pressing plate is pressed on the workpiece for being placed in circular dividing table V-groove, and parallels is located at
Between pressing plate and index table upper table surface, the through-hole that screw rod passes through on pressing plate withstands on the threaded hole of the upper table surface of index table
In, the upper end is limited using nut check.
Connecting shaft and the cooperation of lathe spindle hole have self-locking on base, and the horizontal plane of L-type pedestal is benchmark face；Indexing
The effect of workbench is support workpiece and accurate indexing；Positioning device guarantees that indexing is accurately positioned in workpiece, thus feed turning；
The effect of pressing device be workpiece compress it is easy to process；Connecting shaft is packed into the spindle hole of numerically controlled lathe, unclamps pressure
Nut on tight device, raises pressing plate, workpiece is packed into the orthogonal V-groove on index table, then locking nut,
To compress workpiece, locking nut can be unclamped after processing one end with one end of feed turning three-way connection to the greatest extent by starting lathe,
90 ° or 180 ° of rotary index table, both directly feed the other both ends of three-way connection can be cut respectively.
Further, the connecting shaft connecting with lathe is the Mohs axis of cone.The cone bevel angle of the Mohs axis of cone with lathe spindle
There is self-locking when hole cooperates.
Further, orthogonal V-groove includes a long V-groove vertical with main shaft and one on index table
The short V-groove parallel with main shaft.Long V-groove can limit a freedom degree, and short V-groove is equivalent to two positioning pins and limits two certainly
By spending, but short V-groove replaces straight pin to have the advantages of convenient for mounting and clamping, automatic centering, to guarantee a freedom degree of workpiece
It is limited, accurate positioning is convenient for mounting and clamping.
The configuration of the present invention is simple is easy to make, flexible operation, indexing accurate positioning, guarantees the machining accuracy of workpiece, not only
Convenient for the processing of three-way connection, and the part of T shape can be processed.
