Description

Quick tightening tool suitable for valve rod plug assembly

Technical Field

The utility model belongs to the engineering machine tool field, concretely relates to screw up frock fast suitable for valve rod end cap assembly.

Background

In the process of assembling the hydraulic valve, the most critical step is the assembly of the valve core assembly, and the assembly of the valve core component is the premise of ensuring the qualified assembly of the valve core assembly. In the middle of the assembly of case subassembly, the assembly of valve rod end cap is an indispensable link, nevertheless because the structural problem of case, hollow valve rod or the inside assembly of spring need be put into to partial end cap, have spacing condition in the assembling process, often have inconvenient installation and take, the condition production of unable tightening torque for the assembling process is more difficult, and is inefficient.

Disclosure of Invention

In order to overcome above-mentioned prior art's weak point, the utility model provides a tighten frock fast suitable for valve rod end cap assembly screws up the frock fast through design valve rod end cap assembly, has improved the efficiency of case assembly, has guaranteed the accuracy that valve rod end cap screwed up according to assembly moment.

The utility model discloses a realize through following technical scheme: a quick tightening tool suitable for assembling a valve rod plug comprises a base, wherein a hexagonal prism is arranged on the upper side of the base, and a guide cylinder and two cuboid protrusions are arranged on the lower side of the base; two the cuboid arch is a style of calligraphy and arranges, and two the cuboid arch is arranged in the cylindrical both sides of direction.

Further, the base is a cylinder, and the hexagonal prism, the base and the guide cylinder use the same central axis as a center.

Furthermore, the diameter of the guide cylinder is 1 to 2mm smaller than the diameter of the inner hole of the valve rod plug.

Further, the convex upper flank of cuboid is fixed with the lower surface of base, and the convex medial surface of cuboid is fixed with the direction cylinder.

Furthermore, the inner side surface of the cuboid bulge is an arc surface and is attached to the circumferential surface of the guide cylinder.

Further, all adopt welded fastening between cuboid arch and base, cuboid arch and direction cylinder.

The utility model has the advantages that: the utility model provides a valve rod end cap assembly interfere, the efficiency of case assembly has been improved to the problem of assembly difficulty, has guaranteed the accuracy that the valve rod end cap was screwed up according to assembly moment, has guaranteed assembly quality promptly, has improved the product percent of pass again. And even under the great condition of valve rod end cap, still can effectively screw up, the commonality is strong, all has better suitability to the case assembly of all kinds of hydraulic pressure multiple unit valves.

Detailed Description

The invention is further illustrated below with reference to the figures and examples.

As shown in figures 1 to 3, the quick screwing tool suitable for assembling the valve rod plug comprises a hexagonal prism 1, a base 2, a cuboid bulge 3 and a guide cylinder 4. The upside of base 2 is equipped with hexagonal prism 1, and the downside of base 2 is equipped with direction cylinder 4 and two cuboid archs 3. The size of the hexagonal prism 1 is matched with the size of the torque wrench adapter, the hexagonal prism 1 in the tool can be matched with the torque wrench adapter to be used as an adapter, and can also be used as a handle of the tool to be quickly screwed, and the tool can be placed into the valve rod plug by holding the hexagonal prism 1 by hand, so that the tool is convenient to install and disassemble. The base 2 is a cylinder, and the hexagonal prism 1, the base 2 and the guide cylinder 4 use the same central axis as a center. Two cuboid arch 3 is a style of calligraphy and arranges, just two cuboid arch 3 arranges in the both sides of direction cylinder 4. The diameter of the guide cylinder 4 is 1 to 2mm smaller than that of the inner hole of the valve rod plug, so that the guide cylinder 4 can be placed in the valve rod plug, and the guide function is achieved for placing of the quick screwing tool. After the direction cylinder 4 accomplishes the direction, rotate the protruding 3 last ditch inslot that makes the protruding 3 embedding valve rod end caps of cuboid, when screwing up the valve rod end cap, the protruding 3 valve rod end caps that are used for driving of cuboid rotate.

The upper side face of the cuboid protrusion 3 is fixed with the lower surface of the base 2, and the inner side face of the cuboid protrusion 3 is fixed with the guide cylinder 4. All adopt welded fastening between cuboid arch 3 and base 2, between cuboid arch 3 and direction cylinder 4. As the improvement of this embodiment, the medial surface of cuboid arch 3 is the arc surface (the side that cuboid arch 3 is close to guide cylinder 4 is the medial surface), and the medial surface of cuboid arch 3 laminates with guide cylinder 4's periphery mutually, when fixed for cuboid arch 3 is fixed more firm with guide cylinder 4.

When the tool is used, the guide cylinder 4 is inserted into the valve rod plug, and then the cuboid protrusions 3 are guided to be embedded into the upper groove of the valve rod plug, so that the tool is matched with the valve rod plug. Use moment spanner crossover sub to connect with hexagonal prism 1 mutually, beat the required tightening torque of valve rod end cap can, the design of hexagonal prism 1 has made things convenient for the installation and the taking of frock simultaneously, has further improved assembly efficiency. The utility model discloses a quick tightening frock of design valve rod end cap assembly has improved the efficiency of case assembly, has guaranteed the accuracy that valve rod end cap screwed up according to assembly moment, has guaranteed assembly quality promptly, has improved the product percent of pass again. And even under the great condition of valve rod end cap, still can effectively screw up, the commonality is strong, all has better suitability to the case assembly of all kinds of hydraulic pressure multiple unit valves.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and all changes and modifications equivalent to any simple modifications made to the above embodiments according to the technical spirit of the present invention are all within the scope of the technical solution of the present invention.
