Title:
POSITIONING DEVICE FOR CROSS RAIL IN PROCESSING MACHINE
Document Type and Number:
WIPO Patent Application WO/2004/069469
Kind Code:
A1
Abstract:
A positioning device for a cross rail in a processing machine realizes a hydraulic-less environment. The positioning device is capable of sufficiently bearing large load even when an air cylinder device that cannot produce drive force capable of directly opposing load from the cross rail is used as the drive source. In the positioning device, an engaging portion (22) is provided at either a cross rail (3) or a guide rail (5), and portions (23) to be engaged with which the engaging portion (22) selectively engages are arranged at the other. A swing engaging portion (22) of which projection portion (22A) engages a portion (23) to be engaged is provided as the engaging portion (22), where the projection portion (22A) is swung and projected by driving by an engaging/disengaging device (24) or by urging force released by the driving. Movement of the cross rail (3) is permitted when the swing engaging portion (22) swings or swings back, causing the projection portion (22A) to be swung and engaged with or disengaged from a portion (23) to be engaged.
