Embodiment Construction

[0010] exist figure 1 , figure 2 Among them, the present invention is provided with bed 3 and moving part 1, and screw 7 is fixed on bed 3, and the two sides of screw 7 are respectively fixed with the line track 8 that is parallel with lead screw 7, and slides on two line rails 8 Block 2 is equipped with a supporting plate 5, the supporting plate 5 is fixed on the rear screw nut 6, the moving part 1 is fixed on the front screw nut 4, and the rear screw nut 6 and the front screw nut 4 move synchronously on the screw 7 .

[0011] The line rail 8 of the present invention is fixed on the bed 3, so that the supporting plate 5 can move freely on the line rail 8, the supporting plate 5 has good guiding precision, and the rear screw nut 6 in the supporting plate 5 moves on the leading screw 7. When the lead screw 7 sags and vibrates, the supporting plate 5 can effectively support the deformed area and prevent shaking when passing through the deformed area, because the rear lead scr...

Abstract

The invention relates to the machine tool equipment field, particularly to a horizontal screw lead supporting device, which comprises a bed and a moving component, wherein, the bed is fixed with a screw lead; line rails are fixed on both sides of the screw lead respectively and parallel to the screw lead; a supporting plate is arranged on the two line rails through a sliding block; the supporting plate is fixed on a rear screw lead blot; the moving component is fixed on a front screw lead nut; and the front screw lead nut and the rear screw lead nut move on the screw lead synchronically. The invention can solve high dropping flexibility caused by dead weight of the screw lead and dithering in movement process, and the structure of the supporting device is simple, safe and reliable; and the horizontal screw lead supporting device is mainly characterized in that real-time supporting for the screw lead is realized to achieve the effect of the dynamic support and to keep the moving component run stability in the straight region of the screw lead.

Description

technical field [0001] The invention relates to the field of machine tools, in particular to a horizontal screw support device for eliminating sagging and shaking during ball screw transmission. Background technique [0002] As we all know, when the machine tool has a large stroke and is driven by a horizontal screw, because the screw is too long, the sag deflection caused by the self-weight of the screw is very large. In order to solve this problem, the bearing at the end of the screw is usually used to reduce the screw. The drooping deflection of the rod improves the rigidity of the screw rod, but the effect is not obvious and when the table moves, that is, the screw rod rotates, the eccentricity caused by the drooping of the screw rod causes the whole screw rod to vibrate, which affects the life of the screw rod and affects the motion accuracy. Some machine tool manufacturers use fixed-point support to reduce the sag of the lead screw. This method cannot effectively impr...
