Abstract
The utility model relates to a testing machine for detecting torque of an expanding sleeve, which comprises a machine seat, a loading mechanism composed of a hydraulic pump station, an oil cylinder and an arm of force, a main shaft and a detection fixture. A torque sensor is fixedly connected to the main shaft, and is connected with a program controller through a data acquisition instrument, the output end of the program controller is connected with a display and a printer, and a relay connected with the program controller controls the actions of the electromagnetic valve of the oil cylinder. The loading mechanism exerts torque force on the main shaft, the torque is transmitted to the expanding sleeve of a tested part through the torque sensor, the torque sensor inputs the acquired signals into the controller through the data acquisition instrument, and when the torque exceeds the maximum torque of the detected expanding sleeve in the locked state, the hydraulic cylinder stops supplying oil, and the test is completed. All the testing processes are dynamically displayed through the display screen, the parameters are recorded, and the test results and the dynamic record curve can also be printed for output. The testing machine for detecting torque of an expanding sleeve realizes the automatic control of the entire process, and has the characteristics of accurate measured data and high measurement accuracy.

Background technology
The swelling cover is a kind of mechanically operated connector, be widely used in mechanically operated axle and cover, spool with gearing that needs such as wheel hub connect in, expansion along with range of application, particularly in the application of industries such as precision optical machinery, need provide more accurate torsion to transmit parameter and torsion transmission characteristic curve, traditional measurement method such as stem-winder disc type surveying instrument can't satisfy measurement requirement.
The utility model content
The purpose of this utility model is: a kind of swelling cover machine for testing torsion of measuring accurate height, measuring process robotization control is provided.
The purpose of this utility model realizes by implementing following technical proposals Come:
A kind of swelling cover machine for testing torsion, the load maintainer that comprises support, forms by hydraulic power unit, oil cylinder, the arm of force, main shaft, detect anchor clamps, it is characterized in that: torque sensor is connected on the described main shaft, torque sensor is defeated to be connected with programming controller by data collecting instrument, and the programming controller output terminal is connected with display, printer; The relay control oil cylinder solenoid valve action that programming controller connects.
Described hydraulic power unit is provided with pressure limiting mechanism, on the arm of force that hydraulic jack drives lightening hole is arranged.
Described detection anchor clamps comprise that one is plugged on the interconvertible mandrel on the main shaft, and main shaft and mandrel adopt square hole to cooperate, and are with the interconvertible overcoat of band tapering on the mandrel.
Adopt the swelling cover machine for testing torsion of above structure, apply torsion by the main shaft that is connected with load maintainer, convert the signal of gathering to electric signal input controller by data collecting instrument by torque sensor again, moment is passed to the part to be tested expansion set by torque sensor, when moment surpassed the maximum moment of expanding cover locking, the swelling cover began to skid, and controller is by the action of relay control oil cylinder solenoid valve, the hydraulic cylinder fuel cut-off is finished test process.And test process can also be exported test result and dynamically recording curve printing by dynamically demonstration and reference record of display screen.Whole process has realized robotization control, has the advantages that measurement data is accurate, measuring accuracy is high.
