The utility model content
Technical problem to be solved in the utility model be provide for above-mentioned the deficiencies in the prior art a kind of both can be on have supported the lathe center frame auxiliary clamp mechanism that can make the normal rotation of motion bolt and not affect turning at the motion bolt that carries out turning.
For solving the problems of the technologies described above, lathe center frame auxiliary clamp mechanism of the present utility model is by the following technical solutions: comprise gripping sleeve and rolling bearing, described gripping sleeve forms be used to the trepanning that is set with processed motion bolt, at least be provided with the compressor arm that two butt faces press processed motion bolt outer circumference surface on described gripping sleeve, described rolling bearing axially is installed on gripping sleeve, the outer circumference surface close-fitting of the inner ring of described rolling bearing and gripping sleeve.
The quantity of described compressor arm is eight, and four ends that are positioned at gripping sleeve wherein, other four other ends that are positioned at gripping sleeve, the compressor arm that is positioned at the same end of gripping sleeve are positioned on the same cross section of gripping sleeve and to form annular along the outer circumference surface of gripping sleeve uniform.
The outer circumference surface of described gripping sleeve is provided with front limit ring and the rear spacing ring of axial limiting rolling bearing.
Described front limit ring and the equal spot-welded on of rear spacing ring are on the outer circumference surface of gripping sleeve.
Described compressor arm is stay bolt, and described gripping sleeve is provided with the screwed hole that matches with stay bolt.
the beneficial effects of the utility model are: a rolling bearing is installed on the gripping sleeve because of lathe center frame auxiliary clamp mechanism of the present utility model, like this after auxiliary clamp mechanism is clamped in lathe center frame, make a plurality of thimbles of lathe center frame press respectively the outer ring of rolling bearing and make whole auxiliary clamp mechanism firmly be clamped on lathe center frame, add that gripping sleeve forms be used to the trepanning that is set with processed motion bolt this moment, and be provided with at least the compressor arm that two butt faces press processed motion bolt outer circumference surface on gripping sleeve, after processed like this motion bolt sleeve is contained on gripping sleeve, regulating compressor arm makes the end face of compressor arm press the outer circumference surface of processed motion bolt, processed motion bolt firmly was clamped on gripping sleeve and can makes gripping sleeve synchronize rotation with it this moment, like this in the whole turning process of processed motion bolt, auxiliary clamp mechanism both can be played a supporting role to processed motion bolt, can make again processed motion bolt normal rotation, effective guarantee the normal process of processed motion bolt.
As improvement, the quantity of described compressor arm is eight, four ends that are positioned at gripping sleeve wherein, other four other ends that are positioned at gripping sleeve, the compressor arm that is positioned at the same end of gripping sleeve is positioned on the same cross section of gripping sleeve and to form annular along the outer circumference surface of gripping sleeve uniform, processed like this motion bolt is in compaction process, the thrust that is subject to evenly distributes, processed motion bolt can more firmly be clamped in gripping sleeve, more effective guarantee the synchronize rotation of gripping sleeve with processed motion bolt.
As improvement, the outer circumference surface of described gripping sleeve is provided with front limit ring and the rear spacing ring of axial limiting rolling bearing, by the mode of front limit ring and rear spacing ring, rolling bearing is carried out axial limiting, and is simple in structure, compact, spacing reliable.
As further improvement, described front limit ring and the equal spot-welded on of rear spacing ring are on the outer circumference surface of gripping sleeve, adopt the mode of spot-welded on to install, since can connect more solid and reliablely, can reduce again in welding process the impact on rolling bearing.
As improvement, described compressor arm is stay bolt, and described gripping sleeve is provided with the screwed hole that matches with stay bolt, and stay bolt is bought convenient, and cost is low.
