Abstract

Double rotation people's air defense door frame fixes a position frock fast belongs to people's air defense door frame field for solve people's air defense door frame and piece together the positioning accuracy difficult problem of frame and improve production efficiency. The technical key points of the invention are that two rotatable positioning plates, one large positioning plate and one small positioning plate, are automatically rotated to a limiting position under the action of gravity to realize the positioning function of the door frame angle iron, when the civil air defense door frame is lifted, the two positioning plates can successively follow the upward movement of the door frame angle iron to rotate outwards in a small amplitude, so that the lifting function of the door frame is not blocked and blocked, and after the door frame is completely separated from a tool, the two positioning plates are automatically reset to the limiting position under the action of gravity to realize the functions of efficient positioning production and automatic resetting without operation.

Description

Double-rotation civil air defense door frame rapid positioning tool

Technical Field

The invention discloses a door frame assembling tool, in particular to a civil air defense door frame assembling tool, and belongs to the field of door frame assembling.

Background

For processing the door frame, generally, the door frame needs to be spliced and positioned and then welded, and whether the positioning of the door frame is correct or not directly influences the efficiency of door frame welding production and the shape and size accuracy of the finished door frame. At present, the door frame is processed mainly by manually measuring and splicing frames in the industry, and the defects of no positioning, large product quality fluctuation and low working efficiency exist; and some existing frame splicing tools have complex tool operation, and the door frame is lifted and cannot be automatically separated from the tool, so that the efficiency is not high.

Disclosure of Invention

The utility model provides a frame frock is pieced together fast to people's air defense door frame, as shown in figure 1, characterized by: the device is composed of a rotating pin 1, a supporting seat 2, a limiting plate 3, a positioning plate 4, a limiting block 5, a small positioning plate 6, a small rotating pin 7 and a bottom plate 9. Two sides of the upper end of the positioning plate 4 are respectively provided with an upward protruding positioning point, the middle upper part of the right side is provided with a hole for connecting and fixing the small positioning plate 6, and the lower end is provided with a hole for connecting and rotating the rotating pin 1 to support and rotate. The small positioning plate 6 is in a triangular shape, and a small hole is formed at the large end. Little locating plate 6 is rotatable with little 7 little clearance fit of little rotating pin, and little rotating pin 7 is fixed in the aperture of locating plate 4, little locating plate 6 is blocked to little locating plate 5 of 4 position welding in the locating plate in little locating plate 6 upper left corner, keeps 6 sharp long end levels of little locating plate directional, prevents to overturn the end. The left lower end of the positioning plate 4 is provided with a hole and is connected with the supporting seat 2 through a rotating pin 1, the supporting seat 2 is welded on the bottom plate 9, a limiting plate 3 is welded near the right side of the supporting seat 2, and the bottom plate 9 is fixed on the working platform 10 through bolt connection.

The specific structure of the invention is given by the following drawings and specific implementation, wherein the drawings are a schematic structural diagram of the invention, the second is a schematic structural diagram of a civil air defense door frame, the third is a schematic structural diagram of a positioning plate, fig. 4 is a schematic structural diagram of a small positioning plate, fig. 5 is a schematic structural diagram of a supporting seat, fig. 6 is a schematic structural diagram of a rotating pin, fig. 7 is a schematic structural diagram of a limiting plate, and fig. 8 is a schematic structural diagram of a bottom plate.

Detailed Description

As shown in attached figures 1 and 2, a high-precision civil air defense door frame sample and eight double-rotation positioning assemblies are manufactured, the eight double-rotation positioning assemblies are distributed and installed on the lower peripheral positions of four corners of a door frame angle iron 8, the height is adjusted by means of increasing and decreasing gaskets between a bottom plate 9 and a platform 10, sixteen positioning points at the upper end of eight positioning plates 4 are tightly attached to the lower plane of the door frame angle iron 8, the sixteen positioning points are enabled to be located at the same horizontal height, the double-rotation positioning assemblies are moved simultaneously, the sharp point of a small positioning plate 6 is enabled to be abutted to the peripheral surface of the door frame angle iron 8, the positions of the eight double-rotation positioning assemblies are determined, the eight double-rotation positioning assemblies are fixedly locked on a working platform 10 through bolts, and installation is finished. When four door frame angle irons 8 are respectively hoisted to the double-rotation positioning assembly during door frame assembly, the length direction of the door frame angle iron 8 is ensured to be at the correct position, the periphery of each door frame angle iron 8 is moved to abut against the 6 sharp points of the small positioning plate, and the lower bottom surfaces of the four door frame angle irons 8 are parallel and level and the upper surfaces of the four door frame angle irons are also parallel and level due to the consistent specification of the angle irons 8, the error amount is controlled in the thickness error of the angle iron 8, and the length of the door frame angle iron 8 and the parallelism of the width direction are also ensured. When the welding operation is finished and the door frame angle iron 8 is lifted, the small positioning plate 6 and the positioning plate 4 move outwards along with the upward movement track of the door frame angle iron 8 and are tightly attached to the door frame angle iron 8 to rotate upwards in sequence in a certain range, the door frame angle iron 8 is prevented from being lifted by clamping stagnation, after the door frame angle iron 8 is separated from the tool, the small positioning plate 6 and the positioning plate 4 automatically reset under the action of gravity, and the goal of efficiently positioning, producing and automatically demolding the civil air defense door frame is achieved.
