Abstract
The invention provides a method for detecting a flange face bolt installation torque by using a detector. The method includes: fixing the flange face bolt on the detector, then rotating a torque wrench of the detector, stopping twisting when the preset torque is reached through twisting, thereby reaching the purpose of detecting the flange face bolt installation torque. 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
The invention belongs to the detection field of flange face bolt mounting torque, especially relate to a kind of method of utilizing detection means measure flange face bolt mounting torque.
Background technology
Flange face bolt, owing to possessing good location, locking effect, is widely used in fields such as Aeronautics and Astronautics, boats and ships, war industries.Its relevant criterion has special requirement to the accurate positioning of flange face bolt, convenient and swift, the good aspects such as consistance.This just requires very strict to the mounting torque of flange face bolt, the processing consistance of flange has been proposed to high requirement, within the shape and size of interior angle must being controlled to a tolerance very, could meet the requirement of twisting moment while installing.Generally, the mounting torque of flange face bolt is tested by sampling proportion, can not guarantee that 100% is qualified.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of method of utilizing detection means measure flange face bolt mounting torque, is especially suitable for preventing because of the defective of the flange face bolt mounting torque causing not in place of sampling.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of method of utilizing detection means measure flange face bolt mounting torque, described pick-up unit comprises torque spanner, twisting head and for the locating device of mounting flange face bolt, described torque spanner is provided with the pilot hole for the upper end of described twisting head is embedded, a described twisting lower end is provided with the cavity for described flange face bolt head is embedded
It specifically comprises the following steps:
(1) described flange face bolt is fixed on described locating device;
(2) upper end of described twisting head is inserted in described pilot hole;
(3) the moment size of described torque spanner is set as to the mounting torque size of described flange face bolt;
(4) described flange face bolt head is put into described cavity;
(5) rotate described torque spanner, enforcement twisting, stops twisting during the described moment size setting in reaching step (3);
(6) take out described flange face bolt.
The present invention can also adopt following technical measures:
Described locating device comprises pad with through hole, be positioned at described pad below and for being screwed in the nut on the screw rod of described flange face bolt and being positioned at described nut below and for the locating piece of fixing described nut, described through hole allows that described screw rod passes through.
Described locating piece is arranged in described bench vice.
Described nut is for putting into the hexagonal nut of described locating piece.
Advantage and good effect that the present invention has are: broken and only depended on laboratory to do the classic method that flange face bolt mounting torque is measured in experiment, security is very good, thoroughly solved because laboratory proportional sampling can not guarantee the difficult problem that product 100% is qualified the generation of the defective assembly quality accident causing of twisting moment while having prevented because of installation.The advantages such as that the present invention has is simple and easy to operate, highly versatile, accurate positioning, efficiency is high, testing cost is low.
