Abstract
The utility model relates to a force measuring apparatus, comprising a torque spanner, a sleeve, screws, screw gaskets, and a fixing hole, wherein the center of the upper surface of the sleeve is provided with a square fixing hole, the lower end of the outer surface of the sleeve is uniformly and fixedly provided with three screw gaskets, the three screws are mounted inside the screw gaskets, and the sleeve is prepared by a carbon steel material with an inner diameter of 100 mm. Compared with the prior art, the force measuring apparatus has the advantages that the force measuring apparatus can be rapidly matched with a leading-in apparatus, enables stepless adjustment in a range with a diameter of 100 mm, increases measuring precision, saves test time, omits tools, and reduces test cost.
Description
Technical field
The utility model relates to a kind of device for measuring force of testing use, particularly a kind of device for measuring force of explosion-proof electric apparatus introducing device test usefulness.
Background technology
The electrical equipment that explosive gas atmosphere uses is necessary for electric apparatus for explosive gas, introducing device is critical component that is used for the cable introducing on the explosion-proof electric equipment, these parts must guarantee that cable is compressed and the sealed explosion-proof cavity by reliable, guarantee can not occur owing to the accident of the loosening spark point explosive gas that causes of cable.In GB3836.1-2010 and GB3836.2-2010 standard clear performance requirement and the test method of introducing device.Require in the test screw-down torque of introducing device is measured, the mode that all adopts torque spanner to add tubular key in inspection body at present tests to finish these Interventions Requested.As everyone knows, electric parameter needs according to different electrical equipment, cable size has very big-difference, therefore also can cause the external dimensions of introducing device not of uniform size, will be according to the equipped different tubular key of introducing device size for finishing test, nonstandardly still need customize spanner, not only make test routine loaded down with trivial details, also increase experimentation cost, prolonged test period.
Summary of the invention
In order to reduce experimentation cost, compression test setup time, increase work efficiency, we have developed the device for measuring force of novel introducing device test usefulness, and a kind of easy to operate device for measuring force is provided.The technical scheme that the utility model is taked to achieve these goals is: a kind of device for measuring force, comprise torque spanner, it is characterized in that: also comprise sleeve, screw, screw pad, fixed orifice, described sleeve upper surface center is provided with square fixed orifice, the sleeve outer surface lower end evenly is fixed with three screw pads, and three screws are installed in the screw pad.Described sleeve is that internal diameter is the carbon steel material of 100mm.
The utility model has following advantage compared to existing technology: this device can be fast and introducing device join type, realized the step-less adjustment in the diameter 100mm scope, improved measuring accuracy, saved test period and instrument, reduced experimentation cost.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that the utility model uses constitutional diagram.
Embodiment
As shown in the figure, device for measuring force comprises torque spanner 3, also comprises sleeve 1, screw 2, screw pad 4, fixed orifice 5, and sleeve 1 upper surface center is provided with square fixed orifice 5, sleeve 1 outside surface lower end evenly is fixed with 4, three screws 2 of three screw pads and is installed in the screw pad 4.Sleeve 1 is the carbon steel material of 100mm for internal diameter.
When using device for measuring force, first with the introducing device 6 of required test as in the sleeve 1, be fixed with three screws 2 and tighten, the other end with introducing device 6 is fixed on the work bench vice 7 again, after will have ergometry to insert in the fixed orifices 5 apart from the torque spanner 3 of function, firmly pull torque spanner 3, transmission by device for measuring force, moment of torsion is delivered on the compressing member of introducing device 6, realize that gradually compressing member is to the clamping of dummycable plug, clamp or during seal request, read the measured value of torque spanner 3 when reaching, thereby obtain the moment that applies on the introducing device 6.
Because the screw 2 this tenon mechanisms that clamp that this device is provided with, make the outside dimension of introducing device can be adjusted in the 0-100mm, the usable range of this device is enlarged, be not subjected to introducing device size and standard socket wrench size restrictions, saved test setup time and deposit of tools.Because it is tightr than other modes that screw 2 cooperates with introducing device, thereby realize that torque spanner 3 is more accurate with the centering of introducing device 6, the moment data that therefore measure are more accurate.
Claims (2)
