Abstract

The utility model relates to a reducing bracket tool which mainly comprises a bracket bottom plate, a vertical hook plate, a positioning stud and a lifting hook. The disc-shaped bracket is provided with a plurality of uniformly distributed screw holes, and the positioning stud can be reasonably screwed into the corresponding screw hole according to the size of the lifted bushing, so that the lifted workpiece is prevented from moving and falling off. A vertical hook plate is welded in the middle of the bottom plate, and the hook plate is used for lifting by a lifting hook. The tool is mainly used when the high polymer bushing is lifted and placed in the liquid nitrogen cylinder, and the bushing is contracted in size in a low-temperature environment so as to be convenient to install. The tool structure can be seen to be simple in manufacture, low in manufacturing cost and reasonable and convenient to use, and the problem that workpieces are difficult to put into a low-temperature barrel is well solved.

Description

Reducing bracket tool

Technical Field

The utility model belongs to the technical field of manufacturing auxiliary tools, and particularly relates to a reducing bracket tool.

Background

In the production process, the lifting of the workpiece is an important link, especially the part with a large size or special materials, and besides the improvement of the efficiency, the lifting stability and safety are more important.

The utility model relates to a lifted high polymer bushing part, which has a ring-shaped structure, is used for being embedded in a matched hole and is in interference fit. Therefore, in actual production, the high polymer bushing is frozen at low temperature, the freezing step is carried out in a cylinder filled with liquid nitrogen, and the low temperature can reach about-200 ℃, so that parts cannot be directly put in by hand to prevent skin from being frostbitten, and a tool made of specific materials is required to finish stable lifting and putting in of a workpiece. Although there are many hoisting tools on the market, the structure or the size of the hoisting tool does not conform to the actual hoisting of the product, so that the hoisting tool needs to be manufactured again.

Disclosure of Invention

The utility model aims to provide a diameter-variable lifting tool convenient and quick to operate aiming at the defects in the prior art.

In order to achieve the above purpose, the utility model provides a reducing bracket tool, the whole tool is made of low temperature resistant materials, the low temperature resistant materials are at least capable of bearing the temperature of liquid nitrogen, the tool mainly comprises a bracket bottom plate, a vertical hook plate, positioning studs and lifting hooks, the positioning studs stand on the bottom plate to form a sub-bearing position for bearing annular parts with smaller sizes, a plurality of positioning studs encircle the bracket bottom plate to form a plurality of annular large bearing positions with the inner diameters from small to large, the size of the large bearing position is matched with that of the annular parts with larger sizes, and the bearing position of the tool is manufactured according to the specifications of practical products. The bottom of the vertical hook plate is fixed at the center point of the bottom plate, and the holes on the hook plate are matched with the lifting hooks for use.

The technical scheme of the utility model is further defined as follows:

furthermore, the bracket bottom plate is of a disc structure, the overall external dimension of the bracket bottom plate is determined according to the actual size of a lifting workpiece, a plurality of circles of circumferentially distributed threaded through holes are distributed on the surface of the bottom plate, and the holes are used for detachably connecting the positioning studs.

Further, the vertical hook plate is rectangular in shape, one end of the vertical hook plate is provided with a light hole, and the size of the light hole is determined by the fact that the light hole can be placed into the head of the lifting hook.

Furthermore, the positioning stud is of a cylindrical structure, one end of the positioning stud is provided with threads for being screwed into a threaded hole in the bottom plate, and the column body of the positioning stud (2) is provided with two parallel processing surfaces which are convenient to screw by using a wrench.

Further, the lifting hook is used for lifting the bracket, and the appearance is manufactured in a bending mode and subjected to thermal refining so as to increase the strength of the hook.

Furthermore, the whole tool is made of 304 stainless steel materials. In addition, the tool itself needs to be placed in a liquid nitrogen cylinder along with a workpiece, and in order to prolong the service life of the tool, the tool is made of 304 stainless steel materials, and the material is corrosion-resistant and high in strength.

The variable-diameter lifting tool can conveniently adjust the number and the positions of the positioning studs according to the size of the lifted part, so that the adaptability of the tool is improved, and meanwhile, all materials of the tool are made of stainless steel materials, so that the tool has a long service life and can be particularly used in a low-temperature environment. In conclusion, the tool is simple to manufacture and reasonable to use, and the use requirement of the current product is completely met.

Description of the embodiments

Examples

As shown in fig. 1, the simple disassembly tool comprises a bracket bottom plate 1, a positioning stud 2, a vertical hook plate 3 and a lifting hook 4. The bracket bottom plate is a circular ring-shaped device with a plurality of uniformly distributed screw holes, the screw holes are connected with the positioning studs, and the reasonable positions of the positioning studs are selected according to different hoisting parts on site.

When the tool is used, firstly, the size of a workpiece (bushing) to be lifted is measured, the positions and the number of the installation positioning studs 2 are selected according to the size range of the part, then the workpiece is placed on the bracket bottom plate 1, the workpiece is ensured to be tightly attached to the positioning studs 2 as much as possible, namely, the movement range of the workpiece is ensured to be as small as possible, and finally, the whole tool is lifted by the lifting hook 4 and placed in a required place (in the liquid nitrogen barrel in the example).
