The utility model relates to a torque coefficient testing machine, in particularly a portable digit-display strain meter torque coefficient testing machine which comprises a bracket, a tension sensor that is fixedly arranged inside the bracket and clamped with an axial force transmission mould; wherein, one end of the tension sensor is connected with the clamped axial force transmission mould while the other end is connected with the bracket. The utility model also comprises a torque amplifier and a hand-holding instrument. The tension sensor is connected with the hand-holding instrument through the data cable of the tension sensor, and the torque amplifier is connected with the hand hold instrument through the torque sensor. Thought the use of the utility model testing machine, the on-site construction can be carried out and the torque coefficient can also be directly tested on work-pieces. The defects such as the incorrectness on the torque coefficient existing on the laboratory testing is overcame. Thus the actual axial force of bolts has the same axial force as the designed requirements. In this way, the utility model ensures the reliable correctness on the torque coefficient and the fastening torque value can be directly tested under the designed axial force.
Description
Technical field
The utility model relates to a kind of torque coefficient test machine, specifically relates to a kind of portable Digital-display torque coefficient of on-the-spot test test machine of being convenient to.
Background technology
The instrument of present existing test torque coefficient is to carry out being arranged on the breadboard torsion-testing machine, and the instrument of existing as shown in Figure 1 test torque coefficient mainly comprises dial torque wrench, frame, pulling force transition box, pulling force sensor, will during use.Show tightening torque with dial torque wrench, pulling force sensor conduction torque value, because the friction of test nut support face, consumed very big tightening torque, when lab investigation, the surface of the stress surface that the nut support face is relative there are differences with the surface of the work at scene, that is: friction factor between the two is different in laboratory and scene, just the supporting surface friction torque is that the supporting surface moment of torsion is different, and friction factor K=T
f/ F
fD (T
fFor tightening torque is screw thread moment of torsion and supporting surface moment of torsion sum, F
fAxle power for bolt, d is the nominal diameter of bolt), when the supporting surface moment of torsion of laboratory supporting surface moment of torsion and actual field reality inconsistent, when using the K value to calculate fastener shaft power value by designing requirement at the scene, the axle power and the calculated value of the actual generation of test bolt produce difference, if actual axle power is less than designing requirement, workpiece may take place can not be clamped, test nut loosenings etc. are if bolt fracture greater than designing requirement, may take place in axle power.
Therefore design a kind of device that can satisfy the test of actual field torque coefficient, become the technical barrier that those skilled in the art press for solution.
Summary of the invention
Technical problem to be solved in the utility model provide a kind of can be at the construction field (site), on workpiece the direct portable accurately and reliably Digital-display torque coefficient test machine of test torque coefficient, to overcome the above-mentioned defective that prior art exists, satisfy the needs of on-the-spot torque coefficient test.
The technical scheme of the utility model technical solution problem is as follows:
A kind of portable Digital-display torque coefficient test machine comprises support, is fixedly installed on the interior pulling force sensor of support and clamps-axle power transmission mould; Described pulling force sensor one end with clamp-axle power transmits a mould and is connected, the other end is connected with support, it is characterized in that: also comprise torque dupler and handheld instrument, pulling force sensor passes through pulling force sensor data line connection handheld instrument; Torque dupler links to each other with handheld instrument by the torque sensor data line.
Handheld instrument is made up of the battery in mini-printer, switch, the zeroing of axle power value, liquid crystal display axle power, liquid crystal display moment of torsion, torque value zeroing, keyboard and the instrument, integrated circuit etc.
By above disclosed technical scheme as can be known, the utility model has the advantages that: can the working-yard, on workpiece direct test torque coefficient, difference owing to carrying plane moment of torsion and the actual carrying plane moment of torsion of workpiece when having overcome lab investigation causes torque coefficient untrue, thereby make bolt actual axle power consistent with designing requirement axle power, it has guaranteed torque coefficient accurately and reliably, but also can directly test tightening torque value under design axle power.The test of coefficient in addition, calculating can be finished automatically by this machine of handheld instrument, and printable, also can directly test tightening torque value under design axle power, more accurately and reliably.
