Background technology
In existing various lathes, reach turn-screw more than 6 meters for length, because it is big that its amount of deflection becomes, rigidity reduces, with the movement locus of influence by the feed motion of leading screw drive, reduce the machining accuracy of lathe, therefore need provide secondary support means to the turn-screw of lathe, to improve the rigidity of leading screw, ensure the machining accuracy of lathe, and the unpowered servo-actuated secondary support means of existing lathe turn-screw, as depicted in figs. 1 and 2, comprise the leading screw 1 that is installed on the lathe bed, be arranged on the nut 2 on the leading screw 1, be arranged on the secondary support means of leading screw 1 midpoint, this secondary support means comprises the hydraulic cylinder 5 that is arranged on the lathe bed, pallet 6, guiding test rod 7, hydraulic system, be positioned at the regional travel switch 3 and 4 and the PLC electrical control gear of hydraulic cylinder 5 both sides, leading screw 1 is located by the circular arc groove face on the pallet 6, pallet 6 links into an integrated entity with the piston rod of hydraulic cylinder 5 and the test rod 7 that leads respectively, when 2 motions of the nut on the leading screw 1 are regional between regional sense switch 3 and 4, zone sense switch 3 or 4 sends signal, effect by hydraulic system makes hydraulic cylinder piston rod decline (to the home of design), pallet 6 cancellations are to the aiding support of leading screw 1, so that nut 2 is in this regional trouble-free operation; When the position of nut 2 motion beyond regional travel switch 3 and 4, make pallet 6 be in supporting leading screw state by hydraulic system, thereby realize of the supporting of this secondary support means leading screw 1;
But be not difficult to find out that from the course of work of this secondary support means it has following shortcoming: 1) some supporting only can be provided, limited to the raising of leading screw rigidity; 2) zone between the travel switch 3 and 4 is the blind area of aiding support, loses the supporting role to leading screw in this zone, therefore can not provide continuous supporting to leading screw 1; 3) feed speed of nut 2 is subjected to the restriction of hydraulic system and electrical control gear response speed, so this secondary support means can not be applied to the above high speed leading screw of 20m/min; 4) higher to the reliability requirement of hydraulic system and electrical control gear, cost is higher.
The utility model content
The purpose of this utility model is the above-mentioned deficiency at prior art, a kind of unpowered servo-actuated secondary support means of lathe turn-screw is provided, it can significantly improve leading screw rigidity, leading screw is provided continuous supporting, and can be used for the high speed leading screw, and cost is lower.
For achieving the above object, the unpowered servo-actuated secondary support means of lathe turn-screw of the present utility model, comprise the leading screw that is installed on the lathe bed, be arranged on the nut on the leading screw, it is characterized in that also comprising and be installed on the lathe bed and the guide rail parallel, place two structure of assistant support of nut both sides with leading screw, the servo-actuated bearing that each structure of assistant support comprises the slide block that is arranged on the guide rail, connects firmly with corresponding slide block, the servo-actuated bearing is provided with the radial location structure to leading screw, and two structure of assistant support are by being connected with steel band that it connects firmly;
Above-mentioned servo-actuated bearing can be arranged on hole on the servo-actuated bearing to the radial location structure of leading screw, and the servo-actuated bearing is contained on the leading screw by this borehole jack; In this hole, also be provided with lining,, be convenient to change as consumable accessory;
Above-mentioned servo-actuated bearing also can be arranged on pallet on the servo-actuated bearing to the radial location structure of leading screw, and pallet is provided with the circular arc groove face suitable with leading screw;
The steel band of two structure of assistant support of above-mentioned connection can connect firmly on two servo-actuated bearings;
The steel band of two structure of assistant support of above-mentioned connection also can connect firmly on two slide blocks;
Operation principle of the present utility model is: though when motor by the leading screw drive nut towards where to moving, where move to, nut all promotes to slide on guide rail with the servo-actuated bearing of direction of motion homonymy, another servo-actuated bearing is fixed on two steel bands connections on the structure of assistant support simultaneously and does driven motion, two servo-actuated bearings provide continuous supporting to leading screw simultaneously by the radial location structure, thereby realize the unpowered servo-actuated aiding support to leading screw;
As further improvement of the utility model, between the slide block of each structure of assistant support and servo-actuated bearing, also be provided with the adjustment pad, be convenient to adjust the height of servo-actuated bearing;
In sum, no matter where nut court moves to where to moving, the utility model all has two auxiliary servo-actuated bearings to provide continuous supporting to leading screw, can significantly increase the leading screw rigidity, and can be used for the high speed leading screw; Owing to cancelled hydraulic system and electrical control, reduced cost.
