Description
Technical field
The utility model relates to a kind of bolt checkout equipment, is specifically related to a kind of soft pitch ductility instrument, belongs to testing apparatus technical field.
Background technology
High-strength bolt detector is a kind of instrument detected the axle power of big hexagonal high-strength bolt auxiliary connection (M12, M16, M20, M22, M24, M27, M30).
The high-strength bolt detector of prior art also exists complex structure usually, and acquisition cost is high, and operation comparatively bothers, and reading such as comparatively to bother at the defect.
Therefore, for solving the problems of the technologies described above, the necessary one that provides has structure improved high-strength bolt detector, to overcome described defect of the prior art.
Utility model content
For solving the problem, the purpose of this utility model is to provide a kind of structure simple, and cost is low, the easy to operate and high-strength bolt detector of data intuitive display.
For achieving the above object, the technical scheme that the utility model is taked is: a kind of high-strength bolt detector, and it comprises bearing, Fang Ti, adjusting screw(rod), knurled nut, sensor, interior jig and puller; Wherein, described side's body is installed in the top of bearing, and its left end is provided with an outer chuck, and right-hand member is provided with an end cap; Described adjusting screw(rod) one end is bolted with a hexagonal nut, and the other end is connected with described knurled nut; Described hexagonal nut is connected to the outside of outer chuck; Described sensor is installed on knurled nut, and its one end is connected with interior jig; Described puller is arranged in interior jig.
High-strength bolt detector of the present utility model is set to further: be provided with a upper plate in the top of described interior jig, and this upper plate is connected by screw on interior jig.
High-strength bolt detector of the present utility model is also set to: be provided with a guide rail in the top of described side's body; Be provided with radial ball bearing in guide rail, radial ball bearing is connected by stud and upper plate.
Compared with prior art, the utility model has following beneficial effect: high-strength bolt detector of the present utility model has that structure is simple, and cost is low, easy to operate and plurality of advantages such as data intuitive display.
Accompanying drawing explanation
Fig. 1 is the structural representation of high-strength bolt detector of the present utility model.
Embodiment
Refer to shown in Figure of description 1, the utility model is a kind of high-strength bolt detector, and it is for testing the pulling force of test specimen 100, and it is made up of a few parts such as bearing 1, square body 2, adjusting screw(rod) 3, knurled nut 4, sensor 5, interior jig 6 and puller 7.
Wherein, described side's body 2 is installed in 1 top of bearing, and its left end is provided with an outer chuck 8, and right-hand member is provided with an end cap 9.
Described adjusting screw(rod) 3 one end is bolted with a hexagonal nut 10, and the other end is connected with described knurled nut 4.Described hexagonal nut 10 is connected to the outside of outer chuck 8.
Described sensor 5 is installed on knurled nut 4, and its one end is connected with interior jig 6.
Be provided with a upper plate 11 in the top of described interior jig 6, this upper plate 11 is connected on interior jig 6 by screw 12.Further, a guide rail 13 is provided with in the top of described side's body 2; Be provided with radial ball bearing 14 in guide rail 13, radial ball bearing 14 is connected by stud 15 and upper plate 11, by the cooperation of said structure, can only move back and forth along left and right by spacing interior jig 6.
Described puller 7 is arranged in interior jig 6, and test specimen 100 one end is connected in puller 7, and the other end is connected on end cap 9.
The principle of work of high-strength bolt detector of the present utility model is as follows: be arranged on by test specimen 100 between puller 7 and end cap 9; Hexagonal nut 10 is pulled by spanner, hexagonal nut 10 is made to rotate and be pulled out by adjusting screw(rod) 3 left, adjusting screw(rod) 3 links knurled nut 4, knurled nut 4 makes sensor 5 produce tensile force, sensor 5 pulls interior jig 6 and puller 7, puller 7 pulls test specimen 100 again, thus finally obtains the pulling force of test specimen 100.Meanwhile, by the cooperation of guide rail 13, radial ball bearing 14, carry out the moving direction of spacing interior jig 6.
Above embodiment is only the preferred embodiment of this creation, and not in order to limit this creation, any amendment made within all spirit in this creation and principle, equivalent replacement, improvement etc., within the protection domain that all should be included in this creation.
