Abstract

PURPOSE:To attain the economical efficiency and the safety further the saving of space by forming a turret shaft into a hollow shape, inserting a loader arm shaft to be movably engaged in the axial direction and utilizing turret indexing action and positioning action provided in a turret lathe. CONSTITUTION:When a workpiece W is finished in its work, rotating a loader arm shaft 19 by an index control of a turret device 12 opposing chucks 26, 27 facing to a chuck 5, the chuck 27 is moved to a position of the chuck 5 by a vertical slide 9 and a horizontal slide 6, and the workpiece W, finished in its work, is clamped and removed. Next moving the chuck 26 by the vertical slide 9 and the horizontal slide 6, an unfinished workpiece W is clamped by the chuck 5. Further rotating the loader arm shaft 19 placing the chucks 26, 27 in the bottom direction, the workpiece is advanced by a cylinder 22, positioned on a conveyer 39 and lowered by the vertical slide 9. And positioning the workpiece W on the conveyer 39 by the chuck 27, after the chuck 26 acts holding the workpiece, the finished workpiece W falls off under its own weight by lifting the vertical slide 9, being fed and discharged on the conveyer 39.

Description

[Detailed Description of the Invention] [Industrial Application Field] The invention is based on a numerically controlled talent lathe, in which workpieces that have been separated into feeds in advance are carried to a required processing position, and the processing position η is This relates to a loader that is used to transport the vehicle out of the vehicle.

[Conventional technology]

Conventionally, the axis of the main spindle is horizontal. In the value control loading machine, loading the chuck %0 workpiece, automatic IT for transporting 1 full length,
It was common for 't' to have a loader-scooping robot separate from the machine.帛9The reason is %υ which shows an example of warping.
At the tip, there is a finger for supplying and discharging the workpiece W+ZJ.
A robot arm with a 52t-roposo? S3
Combined with the inquiry type work conveyor S Hiro.

The workpiece W on the workpiece conveyor j is transferred to the spindle chuck 56 of the numerically controlled lathe j5 by the finger 57 of the robot j3.
The workpieces wl, which had been completed in m1, were carried out from the spindle shaft 56 position η' to the workpiece conveyor 51IJ:.

[Problem that the invention seeks to solve]

However, in the above case, since the robot s3 is installed separately from the numerically controlled lathe SS, it requires space and has safety issues, and the robot s3 itself is provided with a function for loading and unloading the work W. This has the problem that it has to be done and is expensive.

Therefore, 1. the present invention makes it possible to load and unload workpieces by skillfully utilizing the turret indexing and turret positioning operations originally developed by numerically controlled turret lathes. P% robot-controlled metallet lathe p
-% of trying to provide goo.

[Failure to solve the problem]

In other words, in the loader of the uninvented numerically controlled turret lathe, the 1 m line slides a horizontal slide parallel to the axis of the main shaft in the left-right direction, and a vertical slide that moves perpendicular to the axis of the main shaft in the gravitational direction. Fit.

The vertical slide is equipped with a tilting device, and the vertical slide is
V. In the numerical control turret indexing with the front and back direction perpendicular to the axis of the turret 4IllIt' cutting main shaft and the moving direction of the vertical slide, fiTJ marking is performed. The axis of the turret shaft is made into a hollow part, and the loader arm shaft is inserted into the hollow part so as to be movable in the axial direction.The loader arm shaft is provided with a drive device for driving in the axial direction, and the tip of the loader arm shaft is provided with a drive device for driving in the axial direction. A loader arm with a biased rotor chuck is attached to the open end of the rotor arm shaft, and the position of the rotor chuck described in 1o is controlled by the horizontal nulling.

Numerical control of the vertical slide and unidirectional control of the rotor arm, and attitude control of the loader chuck.
- It is characterized in that the cutting is performed by indexing control of the ret device.

[For production]

In this invention, the loader chuck is controlled mainly by indexing control of the turret device.
7j, and by controlling the rotor arm IM to retreat and controlling the horizontal and vertical slides, the loader + yack is moved to a required position facing the spindle chuck, and the workpiece is loaded into the spindle chuck, and the workpiece is transferred to the spindle chuck. Unload the workpiece from the chuck and move it to 1i of the turret device.
The loader is controlled by controlling the downward posture of the pIIth+shi control chuck, and by controlling the loader arm C/J reduction and numerically controlling the horizontal slide and vertical slide.
Move the chuck to the work loading/unloading position, grip the low chuck TIC'l-'), and move the loader to the loader.
Unload the workpiece from the chuck.
