Abstract
The utility model discloses a screw supporting device, which comprises a screw for supporting on an engine base, and a nut which is matched with the screw and connected with a working table. The device is characterized in that a left supporting seat which is arranged on the left side of the nut is sheathed on the screw to slide relative to the external surface of the screw, a right supporting seat is arranged on the right side of the nut, a left slide block arranged under the left supporting seat and a right slide block arranged under the right slide block are both matched with line guide rails which are fixed on the engine base, a connection rod is arranged between the left slide block and the right slide block for adjusting distances thereof, a left buffer is arranged on the left slide block, a right buffer is arranged on the right slide block, and the left buffer and the right buffer are both matched with the nut. As two sides of the nut are provided with a sliding support which is matched with the ex-circle of the screw, when the nut drives other components to load-carrying move, the support can restrict the bending deflection of the screw. The screw supporting device has the advantages of guaranteeing straightness of screws in the working process, enhancing rotary precision of screws and providing entire simple structure and flexible and reliable movements.
Description
Technical field
The utility model relates to a kind of screw lead supporting device, mainly is to be used for supporting than long lead screw on the machinery equipment, prevents that leading screw from buckling phenomenon occurring when work is stressed, to improve its running accuracy.
Background technique
In machinery equipment, often can use long leading screw; as the lead-screw driving device in the lathe; its structure is by bearing leading screw to be supported on the support; power plant drive leading screw by transmission part and rotate; the screw that matches with leading screw can move axially along leading screw, thereby drives miscellaneous part such as movable workbench, because leading screw is longer; when stressed, buckling phenomenon can occur, influence its operating accuracy.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, flexibility and reliability, the bending deflection of restriction leading screw, improves the screw lead supporting device of its rotation precision, overcomes the deficiencies in the prior art.
Screw lead supporting device of the present utility model, it comprises the leading screw 3 that is supported on the support 1, is furnished with the screw 6 that joins with worktable 5 mutually with leading screw 3, it is characterized in that: on leading screw 3, be set with the left supporting base 4 and the right supporting base 7 that is positioned at screw 6 right sides that slidably are positioned at screw 6 left sides with respect to leading screw 3 outer surfaces, the left slider 13 of supporting base 4 belows, a left side and the right slide block 9 of right supporting base 7 belows all be fixed on support 1 on linear rail 2 match, be connected to the connecting rod 11 of adjusting its spacing between left slider 13 and the right slide block 9, on left slider 13, be provided with left buffer 12, be provided with right buffer 10 on right slide block 9, left buffer 12 and right buffer 10 all match with screw 6.
Screw lead supporting device of the present utility model, wherein said left supporting base 4 is up and down with right supporting base 7, and two semicircle seat shells fastening forms and is connected with bolt, be provided with cover 8 between each supporting base and leading screw 3, cover 8 is two semiround body fastening moulding and is set in the supporting base.
Screw lead supporting device of the present utility model, owing to the sliding support that matches with the leading screw cylindrical is arranged in the both sides of screw, to drive miscellaneous part stressed when mobile when screw, support can limit the bending deflection of leading screw, guarantee leading screw straightness accuracy in the course of the work, improved the rotation precision of leading screw, overall structure is simple, and flexible movements are reliable.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
As shown in Figure 1: with the lathe is example, and 1 is support, and 5 is with respect to support 1 worktable slidably.By bearing support and bearings leading screw 3 is arranged on support 1, leading screw 3 joins by driving mechanism and power plant.6 is the screw that matches with leading screw 3, and screw 6 joins with worktable 5, and when power plant drove leading screw 3 rotations by driving mechanism, screw 6 can move axially along leading screw 3, drives worktable 5 simultaneously and moves.
