A kind of outer-hexagonal bolt measuring moment coupling arrangement, it relates to a kind of measuring moment coupling arrangement, to solve the connector that the coupling arrangement of existing connection torque spanner and outer-hexagonal bolt is one, there is no fastening means between square key and square groove, affect the problem of the accuracy of measuring moment.First connector is made up of upper cuboid and square key, the upper surface of upper cuboid is provided with square groove, the sidewall of the upper cuboid that square groove is corresponding is provided with two the first tapped through holes, second connector is made up of lower cuboid and cylinder, the upper surface of lower cuboid is provided with link slot, the sidewall of the cuboid that link slot is corresponding is provided with two the second tapped through holes, the lower surface of cylinder is provided with regular hexagon groove, first connector and the second connector setting up and down, and square key coordinates with link slot and installs, be threaded in each first tapped through hole first bolt, be threaded in each second tapped through hole second bolt.The utility model is for measuring the outer-hexagonal Bolt Torque on steam-turbine unit.
Description
Technical field
The utility model relates to a kind of measuring moment coupling arrangement, is specifically related to a kind of outer-hexagonal bolt measuring moment coupling arrangement.
Background technology
The a lot of parts of steam-turbine unit are by some outer-hexagonal bolt-connections, because steam turbine is high-temperature high-pressure apparatus, therefore the bolt-connection of parts not only will have enough moment to tighten, and require that uniform force wanted by one group of attachment bolt, therefore the screwing force of every support bolt will be tried one's best unanimously, the every support bolt uniform force of guarantee, how to realize uniform force, need to detect moment one by one with torque spanner, and torque spanner and bolt-connection need a coupling arrangement to complete, coupling arrangement is in the past the connector be made into integration, the upper surface of connector has and square groove, there is hexagon groove the lower surface of connector, square key on square groove and torque spanner connects joins, the bolt head of hexagon groove and outer-hexagonal bolt connects joins, often kind of outer-hexagonal bolt needs to change a kind of coupling arrangement, and spanner square key is just inserted in square groove, does not have fastening means between square key and square groove, during measuring moment, square key and square groove easily loosen, and cause coupling arrangement can not totally tansitive moment, thus affect the accuracy of measuring moment.Because coupling arrangement is made into integration, the outer-hexagonal bolt of often kind of specification needs to be equipped with coupling arrangement supporting with it, which increases the trouble of replacing, too increases manufacturing cost.
Utility model content
The utility model is the coupling arrangement of the existing connection torque spanner of solution and outer-hexagonal bolt is connector integrally, square key on torque spanner is just inserted in the square groove of connector, fastening means is not had between square key and square groove, causing can not totally tansitive moment, thus affect the problem of the accuracy of measuring moment, and then provide a kind of outer-hexagonal bolt measuring moment coupling arrangement.
The utility model is solve the problems of the technologies described above the technical scheme taked to be:
A kind of outer-hexagonal bolt measuring moment coupling arrangement of the present utility model comprises the first connector, second connector, two the first bolts and two the second bolts, first connector is made up of upper cuboid and square key, the upper surface of upper cuboid is provided with square groove, the sidewall of the upper cuboid that square groove is corresponding is provided with two the first tapped through holes, upper cuboid and square key setting up and down and make one, second connector is made up of lower cuboid and cylinder, the upper surface of lower cuboid is provided with link slot, the sidewall of the cuboid that link slot is corresponding is provided with two the second tapped through holes, lower cuboid and cylinder setting up and down and make one, the lower surface of cylinder is provided with regular hexagon groove, first connector and the second connector setting up and down, and square key coordinates with link slot and installs, be threaded in each first tapped through hole first bolt, be threaded in each second tapped through hole second bolt.
The utility model compared with prior art has following beneficial effect:
One, the first connector of the present utility model passes through the first bolted after connecting with the square key on torque spanner, during measuring moment, can not produce loosening between torque spanner and coupling arrangement, coupling arrangement energy totally tansitive moment, makes the accuracy of measuring moment improve more than 90% compared to existing technology.
Two, for the outer-hexagonal bolt of different size, only need change the second connector just can carry out measuring moment to the outer-hexagonal bolt of different size.Therefore, coupling arrangement of the present utility model saves the replacing operation of the first connector and torque spanner, thus reduces manufacturing cost.
Three, the utility model structure is simple, manufactures easily, is convenient to use on a large scale.
Accompanying drawing explanation
Fig. 1 is overall structure front view of the present utility model, and Fig. 2 is the top view of Fig. 1, and Fig. 3 is the upward view of Fig. 1, and Fig. 4 is the A-A sectional view of Fig. 2, and Fig. 5 is stereogram of the present utility model.
Detailed description of the invention
Detailed description of the invention one: composition graphs 1 ~ Fig. 5 illustrates present embodiment, present embodiment comprises the first connector 1, second connector 2, two the first bolts 3 and two the second bolts 4,
First connector 1 is made up of upper cuboid 1-1 and square key 1-2, the upper surface of upper cuboid 1-1 is provided with square groove 1-1-1, the sidewall of the upper cuboid 1-1 that square groove 1-1-1 is corresponding is provided with two the first tapped through hole 1-1-2, upper cuboid 1-1 and square key 1-2 setting up and down and make one
Second connector 2 is made up of lower cuboid 2-1 and cylinder 2-2, the upper surface of lower cuboid 2-1 is provided with link slot 2-1-1, the sidewall of the cuboid 2-1 that link slot 2-1-1 is corresponding is provided with two the second tapped through hole 2-1-2, lower cuboid 2-1 and cylinder 2-2 setting up and down and make one, the lower surface of cylinder 2-2 is provided with regular hexagon groove 2-2-1
First connector 1 and the second connector 2 setting up and down, and square key 1-2 coordinates with link slot 2-1-1 and installs, and be threaded in each first tapped through hole 1-1-2 first bolt 3, and be threaded in each second tapped through hole 2-1-2 second bolt 4.
