Abstract

The invention relates to a nut looseness preventing structure applicable for screw press especially improvement of nut looseness preventing structure in bolt and slide block device of screw press. The nut has a slot on bottom, a slot on upper part of nut seat, and the two slots are connected and fixed by a flat key. The nut and nut seat outer rim are connected and fixed by a bolt. By dividing the nut into two parts of nut and nut seat and replacing the original straight pin by a flat key, the nut radial bearability can be improved greatly.

Description

technical field [0001] The invention relates to a nut anti-loosening structure applied to a screw press, in particular to the improvement of the nut anti-loosening structure in the screw rod and slider device in the screw press. Background technique [0002] Screw rod and slide block device in the existing screw press machine, its structure is, screw rod and nut are threadedly connected, beat a cylindrical pin on screw rod and nut again and fix to prevent loosening. This kind of nut anti-loosening structure, because the cylindrical pin is difficult to bear the large radial force from the press in the working state, so there is a gap between the screw and the nut, which will cause the nut to loosen until it is damaged, which directly affects the pressure of the press. work efficiency. Contents of the invention [0003] In order to overcome the shortcomings of the above-mentioned prior art, the present invention provides an improved anti-loosening structure for screw press ...
