Abstract
A lead screw lifting opening mechanism comprises a lower base plate, sliding rods are symmetrically arranged on the upper surface of the lower base plate, a screw rod is arranged between the sliding rods and positioned on the upper surface of the lower base plate, limiting plates are arranged on the end surfaces of the screw rod and the sliding rods, a nut block and the screw rod are mutually and rotatably connected, a sliding plate is arranged on the upper surface of a nut block, and the sliding plate penetrates through the sliding rods and the screw rod and is mutually and slidably connected with the sliding rods; this application can improve the vertical accuracy who rises or descend through the screw thread rotation, has reached assurance product quality, improves the beneficial effect of operating efficiency.
Description
Technical Field
The utility model relates to the technical field of machinery, in particular to a screw rod lifting and opening mechanism.
Background
Generally, in the vertical lifting operation with a screw rod, the requirements on the vertical precision and the parallelism of the processing and the assembly of the whole frame are high, so that the high vertical precision is greatly achieved.
Disclosure of Invention
In order to solve the problems, the utility model provides a screw rod lifting and releasing mechanism.
The technical scheme adopted by the utility model for solving the technical problems is as follows: the utility model provides a lead screw lift opening mechanism, includes lower plate, its characterized in that: the lower base plate upper surface symmetry is equipped with the slide bar, it is equipped with the screw rod to lie in the bottom plate upper surface between the slide bar, screw rod and slide bar terminal surface are equipped with the limiting plate, and nut piece and screw rod swivelling joint each other, nut piece upper surface is equipped with the sliding plate, the sliding plate passes slide bar and screw rod and rather than mutual sliding connection.
Furthermore, 1-2 groups of sliding rods are symmetrically arranged on the upper surface of the lower bottom plate.
Further, the outer side surface of the sliding plate is of a circular arc or rectangular structure.
The utility model has the beneficial effects that: this application drives the sliding plate through the nut piece with the mode of screw thread rotation and makes lift vertical motion to the top or below, and the sliding plate then passes slide bar and screw rod and rather than mutual sliding connection, can effectual improvement sliding plate's stability through this mode, and the screw thread rotation can improve the vertical precision that rises or descend, has reached assurance product quality, improves the beneficial effect of operating efficiency.
Drawings
Fig. 1 is a schematic perspective view of an embodiment of the present invention.
Reference numerals: the device comprises a bottom plate 1, a nut block 2, a sliding rod 11, a limit plate 12, a screw 13 and a sliding plate 21.
Detailed Description
In order to make the technical solution of the present invention more apparent, the present invention is further described with reference to the following embodiments.
As shown in fig. 1, a screw lifting and releasing mechanism according to an embodiment of the present invention includes a lower plate 1, and is characterized in that: the upper surface of the lower bottom plate 1 is symmetrically provided with sliding rods 11, screw rods 13 are arranged between the sliding rods 11 and located on the upper surface of the lower bottom plate 1, limiting plates 12 are arranged on the end faces of the screw rods 13 and the sliding rods 11, the nut block 2 is rotationally connected with the screw rods 13, sliding plates 21 are arranged on the upper surfaces of the nut block 2, and the sliding plates 21 penetrate through the sliding rods 11 and the screw rods 13 and are in sliding connection with the sliding rods 13.
Furthermore, 1-2 groups of sliding rods 11 are symmetrically arranged on the upper surface of the lower bottom plate 1.
Further, the outer surface of the sliding plate 21 has a circular arc or rectangular structure.
As shown in fig. 1, when the sliding plate 21 is required to be vertically lifted or lowered by using the present application, the nut block 2 drives the sliding plate 21 to be lifted or lowered vertically upwards or downwards in a threaded rotation manner, and the sliding plate 21 passes through the sliding rod 11 and the screw 13 and is slidably connected with each other.
The above embodiments may be combined with each other and further implemented without being mutually opposed.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and equivalent alternatives or modifications according to the technical solution of the present invention and the inventive concept thereof should be covered by the scope of the present invention.
