Abstract
The utility model relates to a force transformation type electronic torsion testing machine, wherein a mandrel of a torque measurement device is arranged in a tailstock; the torque measurement device comprises a measuring force arm and a force sensor; the force sensor is fixedly arranged away from the mandrel; the measuring force arm is fixedly arranged on the mandrel; an arm body or a tail end of the measuring force arm pushes against a contact of the force sensor; and for the fixed installation mode of the measuring force arm and the mandrel, the measuring force arm is fixedly connected on a transmission sleeve, and the transmission sleeve is tightly hooped on the mandrel by an expansion sleeve or the transmission sleeve is in key connection with the mandrel. In the electronic torsion testing machine, the acting force is obtained by the force sensor; the measuring torque can be obtained by multiplying the acting force with the vertical distance between the force sensor and the mandrel; and owing to the wide measuring range and the high accuracy of the force sensor, the measuring torque obtained also has the characteristics of wide measuring range and high accuracy, thereby overcoming the disadvantages of the prior art.
Description
(1) technical field:
The utility model relates to mechanics of materials checkout equipment, is specially a kind of power change type electronics torsion testing machine.
(2) background technology:
Antitorque transfer to test to metal bar material generally adopts electronics torsion test machine, what its structure comprised coaxial setting reverses head and fixing tailstock, metal bar material is clamped between chuck for handpiece and the tailstock mandrel, on the tailstock mandrel torque sensor is set, chuck for handpiece reverses the moment of torsion that metal bar material produces and directly shows by torque sensor.
Continuous development along with industry, mechanical structured member is constantly done greatly, employed metal bar material increasing diameter is thick, and the electronics torsion test machine of the torque sensor requirement that should test of significant discomfort, trace it to its cause is that the inner structure of torque sensor has limited its specified range, maximum at present moment of torsion range only is 10000N*m, and the low precision of torque sensor does not satisfy accurate test request yet in addition.
(3) utility model content:
The utility model purpose provide the power change type electronics torsion testing machine that a kind of range is big, precision is high.
Can realize the power change type electronics torsion testing machine of above-mentioned purpose, comprise the mandrel that torque-measuring apparatus is installed in the tailstock, different is in the utility model, described torque-measuring apparatus mainly constitutes by measuring the arm of force and force transducer, force transducer and mandrel are separated by a distance to fixedly install, measure the arm of force and be fixedly mounted on the mandrel, measure the arm body or the end of the arm of force and after rotating, conflict on the contact of force transducer.
For being convenient for measuring the installation of the arm of force on mandrel, the described measurement arm of force adopts the drive sleeve form with being connected of mandrel, and the drive sleeve suit is fixed on the mandrel, and the described measurement arm of force is fixedlyed connected with drive sleeve.
The mode that can take to be provided with swelling cover or driving key between mandrel and drive sleeve realizes fixedlying connected of drive sleeve and mandrel.
The described measurement arm of force radially is provided with.
The parallel mandrel below of being located at of described force transducer.
Advantage of the present utility model:
The measuring principle of the utility model power change type electronics torsion testing machine is the size that draws acting force by force transducer, and the vertical range that acting force multiply by between force transducer and the mandrel can obtain measuring torque; Because the range of force transducer is big and the precision height, therefore resultant measurement torque has the big and high characteristics of precision of range equally, has overcome the deficiencies in the prior art.
