ないものであつた。 Loading devices or industrial robots are used to transport workpieces to be gripped by chucks, especially flange workpieces to be reverse-machined.Usually, for example, in Utility Model Publication No. 48-43941, a gripper is used to transfer the machined outside diameter of the first process. After gripping, the unprocessed outer diameter is temporarily placed at a separate position and the unprocessed outer diameter is gripped, and halfway through this process, the chuck is turned over and the processed part is gripped by the chuck to perform the second step of machining. For this reason, the temporary placement operation is cumbersome and loading time is required, and the chuck accuracy at the time of reloading varies, and the current concentric accuracy which requires high accuracy cannot be fully satisfied.

A housing is fixed to the turret in a replaceable manner, and this housing is provided with a replaceable collet guide cylinder having an expandable radial collet plate at its tip and a pressing pin for pressing the collet in the correct posture during loading. An operating rod having a male tapered head that expands is biased to protrude rearward of the housing and is inserted into the collet guide tube, and when the collet guide tube and housing are indexed to the workpiece delivery position, the operating rod is activated. This is characterized in that a piston cylinder device for controlling the blade is separately provided on the tool rest.

働らきをするものである。 Next, the effect will be explained. When the flange workpiece is gripped by the chuck of an NC lathe (not shown) and the first process is completed, the turret is indexed so that the gripping member is at the delivery position, and the tool post is moved so that the gripping member is positioned on the center line of the spindle. , and is sent to the workpiece side and is positioned and stopped at the position where the collect plate 12 is inserted into the hole of the workpiece. At this position, when pressure fluid is sent to the rear chamber of the cylinder 23 of the drive device and the piston rod 25 is advanced, the operating rod 6 is pushed and the tapered portion 6a expands the collet plate 12 outward to grip the inner diameter of the workpiece. When the chuck claw is released, the tool post is positioned at a predetermined position on the tailstock side.
On the other hand, a loading device is positioned at the predetermined position and grips the unprocessed outer diameter side with a gripper. When the pressure fluid in the cylinder 23 of the drive device is switched to the discharge side and the piston rod 25 is moved backward by the spring 26, the operating rod 6 is moved backward by the force of the spring 11, and the collector plate 12 is pushed in by the annular springs 14 and 15 to release the grip. . The tool rest is retracted, and the loading device is positioned so that the workpiece is reversed and the chuck grips the part to be machined in the first step. The turret is sent to the chuck side again, the collet part is inserted into the hole, and the press pin 19 of the collet guide cylinder 13 presses the end face of the workpiece firmly, so that the end face of the workpiece is accurately placed against the axial positioning stand provided at the center of the chuck. Correct. Thereafter, the claws of the chuck are tightened to grip the workpiece, the grippers of the loading device are released, and the loading device is retracted. After evacuation, the specified tool is indexed and the second
Start processing the process. When the workpiece changes, another corresponding gripping member on the turret is indexed and performs the same function.

を得ることができる。 As described in detail above, the present invention provides a collet guide cylinder having a collet member for gripping a workpiece and a pressing member for loading, which can be attached to and removed from the housing as appropriate, and the housing can be attached to the turret selectively in the same way as a tool. allow to be installed and
The drive member for gripping at the delivery position is provided separately on the turret tool post side, so it is easy to handle workpieces by simply replacing only the collet gripping part, and if gripping is not necessary, it can be removed from the housing to handle several types of workpieces. It can easily handle mixed machining of several workpieces. Furthermore, since the drive section is separated, the replacement section is small and easy. Further, since there is no need to transport a workpiece that requires reversal to a remote temporary position during loading, and reversal loading can be performed during the machining sequence, loading time can be shortened and programming can be simplified. In addition, during loading, the workpiece before being gripped by the chuck is pressed in the correct posture by the pressing pin against the axial positioning table provided at the center of the chuck, which improves the gripping accuracy of the chuck and enables the production of products with high finishing accuracy. can.
