Abstract
The utility model relates to the technical field of screw rod transmission of machine tools and discloses a rolling ball screw rod bracket which comprises a lathe bed, a workbench, a rolling guide rail, a left rolling guide rail slide block, a right rolling guide rail slide block, a left support seat, a right support seat, a connecting rod and a screw rod, wherein the workbench is arranged above the lathe bed, the lathe bed is provided with the screw rod, the rolling guide rail is arranged below the screw rod, the left rolling guide rail slide block is arranged at the left side of the rolling guide rail, the right rolling guide rail slide block is arranged at the right side of the rolling guide rail, the left support seat is arranged on the left rolling guide rail slide block, the right support seat is arranged on the right rolling guide rail slide block, and the connecting rod is arranged between the left support seat and the right support seat. In the rolling ball screw rod bracket, two support points which can move following the screw rod are arranged between the support ends of both ends of the screw rod, and therefore, the support points can always exist in the middle during working without the phenomenon that the screw rod droops due to the weight of the screw rod, and the screw rod can not swish when rotating, therefore, the transmission accuracy of the screw rod is improved, the service life of the screw rod is prolonged, and the use effect is good.
Description
Technical field
The utility model relates to the screw mandrel drive technology field of lathe, is a kind of ball screw carriage.
Background technology
If the lathe stroke of lead screw transmission long (greater than 6500mm), the distance of the two end supports end of leading screw is too big, and the leading screw stage casing can cause the leading screw whipping during rotation because the deadweight generation is sagging, reduces the transmission accuracy and the service life of leading screw.
Summary of the invention
In order to overcome existing screw mandrel stage casing because the sagging deficiency of deadweight: the utility model provides a kind of ball screw carriage.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of ball screw carriage, comprise lathe bed, workbench, rolling guide, moving guide rail slide block rolls left, right rolling guide slide block, left side supporting seat, right supporting seat, connecting rod and screw mandrel, described lathe bed top is provided with workbench, described lathe bed is provided with leading screw, described screw mandrel below is provided with rolling guide, the rolling guide left side is provided with the moving guide rail slide block that rolls left, the rolling guide right side is provided with right rolling guide slide block, the moving guide rail slide block that rolls left is provided with left supporting seat, right rolling guide slide block is provided with right supporting seat, is provided with connecting rod in the middle of left supporting seat and the right supporting seat.
The beneficial effects of the utility model are: this ball screw carriage adds two places in the centre of the two end supports end of leading screw can follow the mobile strong point, so just can when work, the strong point all be arranged the centre, with regard to can not occur screw mandrel because self weight and sagging phenomenon, screw mandrel when rotation screw mandrel can whipping yet, improve the transmission accuracy and the service life of leading screw, result of use is good.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Among the figure 1, lathe bed, 2, workbench, 3, rolling guide, 4, the moving guide rail slide block that rolls left, 5, right rolling guide slide block, 6, left supporting seat, 7, right supporting seat, 8, connecting rod, 9, screw mandrel.
The specific embodiment
As Fig. 1 is structural representation of the present utility model, a kind of ball screw carriage, comprise lathe bed 1, workbench 2, rolling guide 3, moving guide rail slide block 4 rolls left, right rolling guide slide block 5, left side supporting seat 6, right supporting seat 7, connecting rod 8 and screw mandrel 9, described lathe bed 1 top is provided with workbench 2, described lathe bed 1 is provided with leading screw 9, described screw mandrel 9 belows are provided with rolling guide 3, rolling guide 3 left sides are provided with the moving guide rail slide block 4 that rolls left, rolling guide 3 right sides are provided with right rolling guide slide block 5, the moving guide rail slide block 4 that rolls left is provided with left supporting seat 6, right rolling guide slide block 5 is provided with right supporting seat 7, is provided with connecting rod 8 in the middle of left supporting seat 6 and the right supporting seat 7.
The operation principle of this mechanism is exactly to increase by two places can follow the mobile strong point in the middle of the two end supports end of leading screw, during workbench 2 feeding from left to right, be fed to feed screw nut right side, a certain position with 7 the left side contact of right supporting seat and drive carriage feeding to the right, when table feed during to low order end, the middle section position that just in time is fed to whole rhizoid thick stick is supported on a left side, during workbench 2 feeding from right to left, be fed to of right side contact and the drive carriage left feeding of feed screw nut left side, a certain position with left supporting seat 6, when table feed during to high order end, the right middle section position that just in time is fed to whole rhizoid thick stick that supports so just can guarantee that all there is the supplemental support point in leading screw leading screw stage casing in total travel.
