Description

Technical Field

[0001] The present invention relates to the field of machining, and particularly to an automatic loading and unloading device for a numerically controlled lathe.

Background Art

[0002] The numerically controlled lathe loading and unloading device is composed of a single truss robot hand, a gripper gripping mechanism on the robot hand, and a stocker outside the numerically controlled lathe. The operation method is that the gripper gripping mechanism on the truss robot hand grips the workpiece waiting for processing at the workpiece chucking point position of the vice (or other clamping mechanism) part of the numerically controlled lathe, takes out the processed product (if there is no processed product for the first time), places it, chucks the product waiting for processing, the truss robot hand leaves the numerically controlled lathe, returns the workpiece to the workpiece pallet, and repeats the above cycle. The conventional numerically controlled lathe loading and unloading device can only complete the chucking of one processing surface at a time, cannot complete the production of finished products of multiple process workpieces with a single machine, or in order to realize the production of workpieces of multiple processing processes with a single machine, it is necessary to manually complete the workpiece switchback, resulting in high labor costs, low production efficiency, insufficient utilization of the machine tool, or using a workpiece logistics distribution system, which is complex and huge, has too large a floor area and is often difficult to realize, with high costs, or using multiple numerically controlled lathes and loading and unloading devices to cooperate. In this way, the cost is also high, the matching ratio of the machine tools is uneven, the machine tools are in an idle state, and the flow of the workpiece also becomes quite slow.

The truss robot hand takes out the processed workpiece (for the first time, there is no processed workpiece), places the unprocessed workpiece A on the vice, and the vice is automatically clamped. 3) The truss robot hand moves away from the numerically controlled lathe and near the position of the article pallet two. 4) While the workpiece is being processed on the numerically controlled lathe, the truss robot hand places the processed workpiece on the article pallet two (for the first time, there is no processed workpiece). 5) Reach the requirement of automatically reversing the processed surface by 180° by the automatic reversing mechanism of the processed surface (for the first time, there is no processed workpiece). 6) The truss robot hand grips the switched-back Work A1 from the article pallet two, sends it up to the article pallet one, and places it (for the first time, there is no processed work), 7) The truss robot hand grips the second unprocessed Work B from the article pallet one, moves it outside the digital control lathe and waits, 8) After the processing of the digital control lathe is completed, the truss robot hand moves near the vice position of the digital control lathe, takes out the processed Work A1, places the unprocessed Work B in the vice, and the vice is automatically clamped. 9) The truss robot hand leaves the digital control lathe and moves near the article pallet two position. 10) While the work is being processed on the digital control lathe, the truss robot hand places the processed Work A1 on the article pallet two. 11) When the requirement of reversing the processed surface by 180° by the automatic reversing mechanism of the processed surface is reached (the article has been switched back), 12) The truss robot hand grips the switched-back Work A1 from the article pallet two, sends it up to the article pallet one, and places it. The above cycle is repeated until all the processes of all the works on the article pallet are completed, eliminating the need for manual maintenance, saving time and labor, and automatically completing the production of finished products with one machine.

[0025] The working procedures 5) and 11) required by the above two types of automatic reversing mechanisms for the processed surface are selected based on the "Combined Operation Method of Automatic Reversing of the Processed Surface and Gripper Gripping" shown in Fig. 15 and the work processing requirements, and the processed surface is automatically reversed based on the software system program of the automatic loading / unloading digital control lathe device.
