HOUSING SUPPORTING STRUCTURE FOR HOUSING GEAR OF MULTI- HEAD SEWING MACHINE

摘要

PROBLEM TO BE SOLVED: To make it possible to fasten a plurality of screw rods to a frame by with nuts even if there is a shape error or accuracy error in a frame by screwing the nuts at a clearances having margins to the extent that the plural screw rods extended downward from the bottoms of housing can be inclined and set within a specific angle range. ;SOLUTION: The housing 12 for housing the gear of respective sewing machines are arranged in the lower part of a bed 5 below a table 2 of the multi-head sewing machines and drive shafts 26 for suttles 10 are born in the state passing through the plural housings 12. When the housings 12 are supported to the frame 30, the plural screw rods 33 extended downward from the bottom of the housings 12 are inserted into the trough-holes pierced at the frame 30. The screw rods are fixed by fastening the nuts 38a and 38b arranged in the vertical positions of the frame 30 and at this time, the degrees of the clearances in the radial direction of the respective nuts 38a and 38b are set at the clearances having the margins to the extent that the angle of the screw rods 33 with respect to the frame 30 can be inclined and set at 91 to 92°.;COPYRIGHT: (C)2001,JPO
