Embodiment Construction

[0023] Such as figure 1 , 2 As shown, the present invention provides a method for measuring the mounting torque of flange surface bolts using a detection device, the detection device comprising a torque wrench 1, a wrench head 2 and a positioning device for fixing flange surface bolts 3, the torque wrench 1 A positioning hole for embedding the upper end of the wrench head 2 is provided, and a cavity for embedding the head of the flange surface bolt 3 is provided at the lower end of the wrench head 2 .

[0024] The positioning device includes a gasket 4 with a through hole, a hex nut 5 located below the gasket 4 and used to be screwed on the screw of the flange surface bolt 3 and a positioning block located below the hex nut 5 and used to fix the hex nut 5 6. The through hole allows the screw to pass through. The positioning block 6 is installed in the bench vise 7. The hexagonal nut 5 can be placed in the positioning block 6, and the opposite side of the hexagonal nut 5 is us...

Abstract

The invention provides a device of detecting a flange face bolt installation torque. The device comprises a torque spanner, a spanner screwing head and a locating device used for fixing a flange face bolt. The torque spanner is provided with a locating hole used for enabling the upper end of the spanner screwing head to be embedded in the locating hole, and the lower end of the spanner screwing head is provided with a cavity used for enabling the head portion of the flange face bolt to be embedded in the cavity. The invention further provides a method of testing the flange face installation bolt utilizing the detecting device. The device and the method of detecting the flange face bolt installation torque break through a traditional method of detecting the flange face bolt installation torque only depending on experiment conducting in a laboratory, are good in safety, thoroughly solve the problem that products cannot be guaranteed to be qualified 100% due to the proportional sampling of the laboratory, and prevent assembly quality accidents caused by unqualified spanner screwing torque in an installation process from happening. The device and the method of detecting the flange face bolt installation torque have the advantages of being easy to operate, strong in generality, accurate in location, high in efficiency, low in detecting cost and the like.

Description

technical field [0001] The invention belongs to the detection field of flange surface bolt installation torque, and in particular relates to a method for measuring flange surface bolt installation torque by using a detection device. Background technique [0002] Flange bolts have been widely used in aviation, aerospace, ships, ordnance and other fields due to their good positioning and anti-loosening effects. Its relevant standards have special requirements for the accurate positioning, convenience, and good consistency of flange bolts. This puts very strict requirements on the installation torque of the flange bolts, and puts forward higher requirements on the processing consistency of the flange. The shape and size of the inner angle must be controlled within a very small tolerance to meet the wrenching torque during installation. requirements. In general, the installation torque of flange bolts is tested by sampling ratio, which cannot be guaranteed to be 100% qualified...
