Abstract
The utility model provides an electric tool moment of torsion accredited testing organization, it includes a base member, is equipped with rotary main shaft on the base member, is equipped with chuck butt joint electric tool's output shaft on the main shaft, still is equipped with encoder, torque sensor on the main shaft, encoder and torque sensor all with a central controller feedback connection, be equipped with in the base member on clutch acts on the main shaft, clutch can the rotatory main shaft of instantaneous prevention, the main shaft on still set the magnetic controller, the magnetic controller is connected with the central controller electricity. The device can realize the rotatory unexpected urgency of main shaft and stop, can record peak value moment of torsion data through torque sensor in the twinkling of an eye, and the device also can record static moment of torsion and dynamic torque value simultaneously.
Description
Technical field
The utility model belongs to electric tool detection technique field, particularly a kind of electronicInstrument torsion-testing mechanism.
Background technology
Electric tool needs to measure its durability in qualified one, and must test electronicThe moment of torsion of instrument. The torsion-testing of existing electric tool can only be to provide static state, dynamicData, the peak torque data that can not test electric tool.
Summary of the invention
The purpose of this utility model is the problem existing for existing electric tool test,And provide a kind of mechanism for testing of testing electric tool peak torque.
The purpose of this utility model can realize by following technical proposal: a kind of electronic workTool torsion-testing mechanism, it comprises a matrix, matrix is provided with rotary main shaft, main shaftThe output shaft that is provided with chuck docking electric tool, is also provided with encoder, moment of torsion on main shaftSensor, described encoder and torque sensor all with a central controller feedback link,It is characterized in that, in described matrix, be provided with arrangement of clutch and act on main shaft, clutch dressThe main shaft of putting the instantaneous prevention rotation of energy, is also equipped with magnetic controller on described main shaft,Magnetic controller is electrically connected with central controller.
Described arrangement of clutch comprises brake holding cylinder, and described main shaft is provided with groove, brake holdingThe piston rod of cylinder and main shaft radial parallel, the head correspondence of piston rod is on groove.
Described groove annular is located on main shaft, and groove is from shallow to deep from main shaft surfaceContinue to axle center.
Described brake holding number of cylinders has two, and is located at the both sides of main shaft.
Compared with prior art, this device can be realized the unexpected emergency brake of main shaft rotation, can winkBetween record peak torque data by torque sensor, this device also can record static state simultaneouslyMoment of torsion and dynamic torque value.

In figure, 1, matrix; 2, torque sensor; 3, encoder; 4, main shaft; 5,Brake holding cylinder; 6, magnetic controller; 7, hexagonal chuck; 8, groove.
Detailed description of the invention
Below specific embodiment of the utility model by reference to the accompanying drawings, to the utility modelTechnical scheme be further described, but the utility model is not limited to these embodiment.
Shown in Fig. 1,2, the utility model comprises a matrix 1, and matrix 1 is provided with and revolvesTurn main shaft 4, main shaft 4 is provided with hexagonal chuck 7 and docks the output shaft of electric tool. MainOn axle 4, be also provided with encoder 3, torque sensor 2, be provided with magnetic at the tail end of main shaft 4Controller 6, encoder 3, torque sensor 2, magnetic controller 6 all with central authoritiesController feedback link.
And being provided with the main shaft 4 of arrangement of clutch for emergency brake rotation, arrangement of clutch comprises brake holdingCylinder 5, brake holding cylinder 5 quantity have two, and are located at the both sides of main shaft 4. Main shaft 4Be provided with groove 8, groove 8 annulars are located on main shaft 4, and groove 8 from shallow to deepContinue to axle center from main shaft 4 surfaces. The piston rod of brake holding cylinder 5 and main shaft 4 are radially flatOK, the head correspondence of piston rod on groove 8, when piston rod automatic during near main shaft 4Fall into groove 8, in order to limit the rotation of main shaft 4. Above-mentioned magnetic controller 6 withArrangement of clutch supports the use, and turns round by the peak value that torque sensor 2 feeds back electric toolSquare data, static torque and dynamic torque value.
