Embodiment
Core thinking of the present utility model is, designs a kind of bolt simulator, not only can simulate the state that bolt is locked, can also simulate bolt be locked after the state of deformation, ensure that with this dynamic wrest fixing instrument obtains testing result accurately.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of bolt simulation mechanism of surely turning round in tool detection device, comprises bolt simulator 1 and the sensor module 2 of coaxial connection.
As shown in Figure 2, bolt simulator 1 comprises shell 4, cubic thread bush 9, dish spring 11, locking compression assemblies and spacing ring 3.Wherein, cubic thread bush 9 is plugged on the inside of shell 4, and dish spring 11 is sleeved on the outside of shell 4, and locking compression assemblies is arranged on the front end of shell 4, and spacing ring 3 is fixed on the rear end of shell 4.The concrete syndeton of above-mentioned each parts is as follows:
Be provided with the cubic hole that a circle is surrounded by inner convex platform in the inside of shell 4.Four directions thread bush 9 is provided with the cubic cylinder of threaded hole in being, cubic thread bush 9 inserts cubic hole and forms slidably clearance fit, turns up and can offset with inner convex platform in the rear end of cubic thread bush 9.The outside of shell 4 is provided with a circle outer lug boss, and dish spring 11 is socketed between the front end and outer lug boss of shell 4.Spacing ring 3 is fixed on the rear end face of shell 4.Locking compression assemblies is sleeved on the front end of shell 4, and tight lock part is fixedly connected with the front end of cubic thread bush 9, and press section and tight lock part are fixed and offseted with dish spring 11, and dish spring 11 is squeezed in outer lug boss.
Locking compression assemblies specifically comprises clamping screw 12, locating ring 6 and pressing plate 7.Locating ring 6 is sleeved on the front end of shell 4, forms slidably clearance fit with shell 4.One end of locating ring 6 exceeds the end face of shell 4 front ends, and the other end touches mutually with dish spring 11, for the outside boss direction of dish spring 11 is implemented to extruding.Pressing plate 7 covers the endface position at locating ring 6.Clamping screw 12 is screwed in threaded hole by the front end of cubic thread bush 9 through the center of pressing plate 7, and fixing with pressing plate 7 and cubic thread bush 9 respectively by Double-ended nut 5.
