Machining machine and machining production line with machining machine

Abstract

The invention provides a machining machine and a machining production line with the machining machine. and a workpiece (5) on an M / C table (2a) is subjected to piercing processing through a drill bit(2h) arranged at a connection portion (2d); after the piercing processing is completed, the drill bit (2h) is removed from the connection portion (2d);a workpiece jig (2i) is arranged at the connection portion (2d); then, the connection portion (2d) is lowered, the workpiece jig (2i) clamps the pierced workpiece (5) to lift the connection portion (2d), and the workpiece (5) is temporarily held onthe M / C table; and under the state, a next workpiece (5') is carried onto the M / C table(2a). By temporarily holding the pierced workpiece (5) on the M / C table, the next workpiece (5) can be easily carried onto the M / C table. Therefore, the carrying and unloading operations of the workpieces can be easily carried out; at the same time, a temporary storage field is no longer required; and the machining efficiency is improved.

Description

Technical field [0001] The present invention relates to general-purpose processing machines such as processing machines for machining raw materials (hereinafter also referred to as workpieces) or processing centers (hereinafter also referred to as M / C) that perform various types of machining by exchanging processing tools, And a machining production line with multiple machining machines. Background technique [0002] In the past, in the production line of an automatic transmission (hereinafter also referred to as A / T), a machining production line for performing various machining processes on a workpiece as a structural component of the A / T was installed. The machining production line includes a plurality of M / Cs arranged along the production line, and a manipulator for placing workpieces on and taking out the workpieces from the worktables of these M / Cs. In addition, the same machine production line is also installed in the production line of machinery other than A / T. [0003] As...

AI Technical Summary

Problems solved by technology

Therefore, the manipulator 13 must reciprocate, and there is still a lot of wasted time in the machining operation, and the efficiency of the machining operation is not high.

[0023] Furthermore, since it is necessary to install a temporary storage area for the workpiece 5 between the M / C, the corresponding installation space must be considered, and the machining line 1 must be enlarged.
