Abstract
The utility model discloses a side force-free automatic detection device for a torque wrench. The side force-free automatic detection device for the torque wrench comprises a standard torque sensor, a wrench body, a driving device and a control system, and is characterized by also comprising a side force elimination device and a calibration device, wherein the side force elimination device is arranged on the standard torque sensor, and is connected with the wrench body; the wrench body is connected with the calibration device and the driving device; and the calibration device, the standard torque sensor and the driving device are connected with the control system. In such a way, the magnitude of a loading force value can be accurately controlled and adjusted, so that a test is accurate and reliable, and damage to the torque wrench in the test is avoided; and moreover, the device can be automatically operated, so that the labor intensity of a detector is reduced.
Description
Technical field
The utility model belongs to the mechanical gage equipment technical field, and particularly a kind of torque wrench is without the side force automatic calibrator.
Background technology
Torque wrench is very extensive in daily use, in the production and process on probation of spanner, all requires the moment of torsion of torque wrench is measured and calibrated.Present torque spanner normalizing device mainly applies moment by calibration personnel direct pull spanner, perhaps rotates handwheel by calibration personnel and by screw mandrel torque wrench is applied moment.Because existing detection mode is so that there is side force in torque wrench in testing process, the result often makes the testing calibration data of torque wrench inaccurate, and owing to being to adopt the artificial application of force, the bad control of application of force size, sometimes applying the excessive torque wrench that causes of moment damages, have calibration personnel sometimes to need the application of force that constantly repeats, labour intensity is very large again.
The utility model content
For above-mentioned the deficiencies in the prior art, it is accurate that the utility model main purpose provides a kind of measurement, and calibration accuracy is high, and the torque wrench of high efficiency is without the side force automatic calibrator.
For achieving the above object, the utility model adopts following technical scheme: a kind of torque wrench is without the side force automatic calibrator, comprise a standard torque sensor, one wrench body, one drive unit and control system, described torque wrench also comprises a side force cancellation element without the side force automatic calibrator, one calibrating installation, described side force cancellation element is located on the described standard torque sensor and with described wrench body and is connected, described wrench body is connected with described calibrating installation, described wrench body also is connected with described drive unit, described calibrating installation, standard torque sensor, drive unit all is connected with described control system.
Preferably, described side force cancellation element is bearing.
Preferably, be provided with PLC or single-chip microcomputer or computer in the described control system, be used for controlling the operation of each parts in the whole device, and carry out data transfer and analysis.
Technique scheme has following beneficial effect: 1, this torque wrench is simple in structure without the side force automatic calibrator, and cost is low, and precision is high, and is applied widely; 2, drive unit is connected with control system, has realized that the fast and stable of moment of torsion loads, and has improved efficient; 3, can control accurately and regulate the size of loading force value, make test more accurately and reliably, avoid damaging torque wrench in the test; 4, moment of torsion applies without side force and disturbs, and measurement result is more accurate.
Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of specification, below with preferred embodiment of the present utility model and cooperate accompanying drawing to be described in detail as follows.The specific embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.
Description of drawings
Fig. 1 is that the utility model torque wrench is without the structural representation of side force automatic calibrator one preferred embodiment.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail.
Please refer to Fig. 1, this torque wrench comprises control system 1, standard torque sensor 6, wrench body 4, drive unit 2, side force cancellation element 5 and calibrating installation 3 without the side force automatic calibrator.Side force cancellation element 5 is located on the standard torque sensor 6 and with wrench body 4 and is connected, and wrench body 4 is connected with calibrating installation 3, and wrench body 4 also is connected with drive unit 2.Calibrating installation 3, standard torque sensor 6, drive unit 2 all are connected with control system 1, are controlled controlling of system 1.
This torque wrench is connected wrench body 4 heads without the side force automatic calibrator in use with side force cancellation element 5, the torque sensor of wrench body 4 self is connected with calibrating installation 3, and drive unit 2 is connected with the point of application of wrench body 4.
During the test beginning, control system 1 accessory drive 2 is used for masterpiece the point of application of wrench body 4, the moment of torsion that produces is delivered on the standard torque sensor 6 after eliminating side force by side force cancellation element 5, standard torque sensor 6 is delivered to the data that measure in the control system 1, compare with the data that wrench body 4 shows self, thereby finish test.Need calibration if test result shows wrench body 4, then control system 1 control calibrating installation 3 is calibrated wrench body 4 online.
1), this torque wrench is simple in structure without the side force automatic calibrator this torque wrench has the following advantages without the side force automatic calibrator:, cost is low, and precision is high, and is applied widely; 2), drive unit is connected with switch board, realized that the fast and stable of moment of torsion loads, and improved efficient; 3), can control accurately and regulate the size of loading force value, make test more accurately and reliably, avoid damaging torque wrench in the test; 4), realize automation mechanized operation with powerful data-handling capacity, and reducing human error, alleviated testing person's labour intensity; 5), moment of torsion applies without side force and disturbs, measurement result is more accurate, 6), the torque wrench on-line calibration, frontier inspection is surveyed the limit calibration, and is quick and convenient.
Above a kind of torque wrench that the utility model embodiment is provided is described in detail without the side force automatic calibrator; for one of ordinary skill in the art; thought according to the utility model embodiment; all will change in specific embodiments and applications; in sum; this description should not be construed as restriction of the present utility model, and all any changes of making according to the utility model design philosophy are all within protection domain of the present utility model.
