Abstract

In an automatic chuck jaw change system, a combined machining lathe capable of positioning with high precision and a robot with lower positioning precision than the combined machining lathe cooperate to automatically change a chuck jaw. The system includes a robot (50) disposed in front of the combined machining lathe, and the robot (50) can be selectively mounted on a front end of an arm (52) thereof with a work hand for operating a work (60), a chuck jaw (70), and a nut runner hand (80) for operating a drive mechanism of the chuck. The robot cooperates with a tool for jaw mounted on a tool spindle of the combined machining lathe to automatically change a chuck jaw of a main spindle.

Description

technical field

[0001] The invention relates to an automatic exchange system for chuck jaws of a compound processing lathe. Background technique

[0002] Since the compound machining lathe can process various workpieces, it is necessary to prepare chuck jaws corresponding to the shape and structure of the workpiece.

[0003] The following patent documents disclose a chuck jaw replacement system device and the like of a compound machining lathe.

[0004] In addition, in order to allow the multi-function lathe to operate unmanned and automatically for a long time, it is necessary to equip the multi-function lathe with a robot that transports workpieces in and out.

Embodiment Construction

[0029] FIG. 1 is a plan view showing the overall configuration of a chuck jaw replacement system of a combined machining lathe according to the present invention.

[0030] This system has a multi-joint robot 50 equipped in front of a compound machining lathe 10 .

[0031] The robot 50 has a body 51 and an arm 52 extending from the body 51. A workpiece hand 60 for holding a workpiece and a pliers 70 for holding a chuck jaw are selectively installed on the front end of the arm 52 to release the spindle from the compound processing lathe 10. Lock the nut wrench 80 on the chuck. Each hand is placed on its own stage.

[0032] A workpiece supply station 90 , a pallet conveying device 100 for conveying pallets to the workpiece supply station 90 , and the like are installed on the side of the composite machining lathe 10 .

[0033] In addition, a shelf-shaped claw storage room 110 is also arranged.

[0034] The robot 50 is represented by symbol E in FIG. 1 1 The area shown as the ...
