Abstract
The utility model discloses a torque wrench calibrating apparatus, which comprises a horizontal bench, a torque sensor, a supporting rod vertically fixed on the horizontal bench and a torque wrench to be calibrated, wherein a handle of the torque wrench is horizontally fixed on the supporting rod, and the other end is connected with the torque sensor through a connector; the horizontal bench is internally provided with a motor, the supporting rod can rise and fall, and the bottom part of the handle of the torque wrench is provided with an angle sensor used for detecting an angle between the handle and the horizontal direction. The angle sensor can monitor whether a handle axis of the torque wrench and the horizontal bench are kept to be horizontal or not at any time by adopting the structure disclosed by the utility model, and deliveries detected information to a PLC (programmable logic controller) so as to instruct the supporting rod to carry out lifting adjustment, thereby enabling the handle axis of the torque wrench and the horizontal bench are kept to be horizontal, enabling the torque wrench to be detected to be not interfered by other external forces when loaded, and being more accurate in detection result.
Description
Technical field
The present invention relates to a kind of verifying attachment, particularly a kind of torque wrench instrument.
Background technology
On July 17th, 2013, disclosed No. 201320111706.6 Chinese utility model patent, disclosed a kind of dial torque wrench standard calibrating device, comprised worktable, motor, torque sensor, vertical support bar and dial torque wrench to be examined and determine; The handle level of this dial torque wrench is fixed on support bar, and its other end is by connecting torque sensor.Motor can drive constant torque wrench to be checked to rotate and electronic loading, has substantially solved External force interference problem when dial torque wrench torsion loads, but has also brought new problem.Newly, when examining and determine torque spanner and vertical support bar or install with torsion torque sensor, may make torque spanner to be examined and determine occur tilt phenomenon, torque spanner to be examined and determine is out-of-level, and has occurred new External force interference, thereby makes verification result deviation.
Summary of the invention
The technical problem to be solved in the present invention is for above-mentioned the deficiencies in the prior art, and provides one can make constant torque wrench maintenance level to be checked, verification result torque wrench instrument accurately.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of torque wrench instrument, comprises horizontal table, torque sensor, is vertically fixed on support bar on horizontal table and dial torque wrench to be examined and determine; The handle level of this dial torque wrench is fixed on support bar, and its other end is connected with torque sensor by connector; In horizontal table, be provided with motor, described support bar liftable, the handle bottom of dial torque wrench is provided with to detect the angular transducer of handle and horizontal direction angle.
On described support bar, be provided with displacement transducer.
Also comprise PLC, described support bar can slide along horizontal table.
The present invention adopts after said structure, the handle axis that above-mentioned angular transducer can be monitored dial torque wrench at any time whether with horizontal table maintenance level, and detection information is passed to PLC, PLC is according to testing result, instruction support bar carries out lift adjustment, makes handle axis and the horizontal table maintenance level of dial torque wrench, makes wait the torque spanner of examining and determine when loading, be not subject to the interference of other external force, testing result is more accurate.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of torque wrench instrument of the present invention.
Wherein have: 1. horizontal table; 2. motor; 3. torque sensor; 4. support bar; 5. dial torque wrench; 6. connector; 7. handle; 8. angular transducer; 9. displacement transducer; 10.PLC.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further detailed explanation with concrete preferred embodiments.
As shown in Figure 1, a kind of torque wrench instrument, comprises horizontal table 1, torque sensor 3, is vertically fixed on support bar 4 on horizontal table 1 and dial torque wrench 5 to be examined and determine; Handle 7 levels of this dial torque wrench 5 are fixed on support bar 4, and its other end is connected with torque sensor 3 by connector 6; In horizontal table 1, be provided with motor 2, described support bar 4 liftables, handle 7 bottoms of dial torque wrench 5 to be examined and determine are provided with to detect the angular transducer 8 of handle 7 and horizontal direction angle.Also comprise PLC10, on described horizontal table 1, be provided with slideway, support bar 4 can slide along horizontal table 1, makes this device can adapt to the dial torque wrench to be examined and determine 5 of different handle 7 length.On described support bar 4, be provided with displacement transducer 9.This displacement transducer 9 can accurately be controlled by PLC 10 lifting distance of support bar 4, prevents the range deviation that manual lifting brings.
Before use, above-mentioned dial torque wrench 5 and torsion torque sensor 3 need through special precise test.
The processes such as installation, installation check and calibrating, handle 7 axis that above-mentioned angular transducer 8 can be monitored dial torque wrench 5 at any time whether with horizontal table 1 maintenance level.If when angular transducer 8 has angle show and exceed set angle, angular transducer 8 can pass to PLC 10 by detection information in time, PLC 10 is according to testing result, instruction support bar 4 carries out lifting one predetermined distance (before use, need the conversion relation of set angle value and lifting distance), make handle 7 axis and the horizontal table 1 maintenance level of dial torque wrench 5, make wait the torque spanner 5 of examining and determine when loading, be not subject to the interference of other external force, testing result is more accurate.
