Description
Technical field
The invention belongs to the devices that measurement verification technical field more particularly to a kind of bolt torsion tester torque are examined and determine.
Background technology
The equipment that bolt torsion tester is detected as steel construction with high intensity hexagon-headed bolt torque coefficient, principle are
By application torque T of the testing machine on nut, bolt pretension P is measured by axle power, then by formula K=T/（P·d）
Calculate torque coefficient of bolt, the prestretching force value and torque value of testing machine whether be accurately directly related to sample detection as a result, although
Machine for testing torsion each year through metering validation activity calibration, but since the precision of equipment sensor in use may
Drift is generated, influences the accuracy of test result, it, need to be before each experiment to experiment in order to ensure test result accurately and reliably
Machine torque and axle power meter are examined and determine, and axle power meter is small, and censorship is convenient, but testing machine censorship is inconvenient, it is necessary to make torque inspection by oneself
Determine accessory.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of auxiliary dress based on the calibrating of bolt torsion tester torque
It puts, for the self-test of testing machine torque.
The present invention is being realized by a kind of device such as lower structure：It is pulled including interior six square socket, connecting rod, digital display torque
Hand, weight, described connecting rod one end are six square toes, and the other end is square head, and six square toes of connecting rod are plugged on interior six square sockets
Interior, the digital display spanner is plugged in the square head of connecting rod, and weight is lifted on the arm of force of force moment spanner with digital display.
The torque being applied in order to facilitate adjusting on force moment spanner with digital display, the weight is multiple counterweights by varying in weight
Composition.
The present invention so works：Force moment spanner with digital display censorship is demarcated, the device of the invention is passed through into interior six square set
Cylinder is fixed on torque scale, firing test machine, reads the torsion in the torque value and force moment spanner with digital display shown on testing machine
Whether square numerical value is met the requirements by the torque value of numerical value contrast judgement testing machine, testing machine torque is examined and determine.
The present invention is made up of a kind of based on bolt torsion test interior six square socket, connecting rod, force moment spanner with digital display, weight
The auxiliary device of machine torque calibrating, is installed by the torque scale of interior six square socket and testing machine, passes through six square toes of connecting rod
It is convenient and efficient with square head respectively with interior six square socket and force moment spanner with digital display grafting, torque is applied by weight, passes through digital display
The torque value of torque spanner is compared with the torque value shown by testing machine, realizes the torque calibrating of testing machine.
