Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is done to concrete introduction.
The adjusting bolt assembly is for a vitals on automobile light-modulating motor, and as shown in Figure 1, concrete structure is that an adjusting bolt 1 made of iron is pressed in the screw mandrel 2 that the POM material makes to its structure, between adjusting bolt 1 and screw mandrel 2, is interference fit.So-called torsional test just refers to exchanges the relative torsion that joint bolt 1 and screw mandrel 2 apply a certain size, and in the utility model, we are called target torsion by this torsion.If under this target torsion, relative rotation does not occur with screw mandrel 2 in adjusting bolt 1, and this assembly is certified products; Otherwise counterrotating words occur with screw mandrel 2 in adjusting bolt 1, and this assembly is unacceptable product.
Referring to Fig. 2 and Fig. 3, the torsional test tool that is applicable to the adjusting bolt assembly of the present utility model comprises: torsionmeter 3, for the torsion aluminum barrel 4 of fixing screw mandrel 2, for the fixed block 5 of secured adjusted bolt 1, with fixing the first inductive disks 6 of torsion aluminum barrel 4, for controlling the first photoelectric sensor 7 of detecting the first inductive disks 6 position of rotation, with fixing the second inductive disks 8 of fixed block 5, for controlling the second photoelectric sensor 9 that detects the second inductive disks 8 positions, motor 10 and the gear train 11 that drives fixed block 5 to rotate.Thereby fixed block 5 rotates torsion aluminum barrel 4 and apply torsion between adjusting bolt 1 and screw mandrel 2, and torque magnitude is read by torsionmeter 3.
From Fig. 1, we can find out, screw mandrel 2 has the lug boss vertical with length direction 201, torsion aluminum barrel 4 is ingenious this structure of having utilized just, a groove structure with lug boss 201 respective outer side edges is set on torsion aluminum barrel 4, when torsion aluminum barrel 4 drops to certain position, thereby the groove structure just in time coordinates and clamps screw mandrel 2 with lug boss 201.
Further, this tool also comprises for adjusting the elevating mechanism of torsionmeter 3 and torsion aluminum barrel 4 height.Preferably, elevating mechanism comprises: slide rail 12 and the cylinder 13 for realizing lifting.
In order to understand better the utility model, the use procedure of tool is summarized as follows: adjusting bolt 1 is fixed on fixed block 5, then the height of torsion aluminum barrel 4 is dropped to and just in time clamps screw mandrel 2; Starter motor 10, under the driving of gear train 11, fixed block 5 rotates, in fact gear train 11 is by a plurality of gear mix proportions, because adjusting bolt 1 and fixed block 5 are fixed together, so adjusting bolt 1 also just must be rotated, drive with the screw mandrel 2 of its interference fit and rotate, in this process, torsion aluminum barrel 4 will apply torsion to screw mandrel 2, and the size of torsion can read from torsionmeter 3.
In actual testing process, torque magnitude often has a desired value, and such as standard commonly used on market is 3.5Ncm, this tool can be neatly according to market demand target setting torsion, and 3.5Ncm herein is only one and illustrates.Whether product is qualified when judging that easily torque magnitude reaches target torsion, and the first inductive disks 6 is provided with the induction breach, and when torsion reaches target torsion, its induction breach is just in time detected by the first photoelectric sensor 7, and representative products is certified products.Then motor 10 reversions, torsion is progressively cancelled, and the adjusting bolt assembly is returned to original state, by the second inductive disks 8 and the second photoelectric sensor 9, cooperatively interacts to control rotary position, and control principle, with the first inductive disks 6, does not repeat herein.
If relative rotation has occurred with screw mandrel 2 in adjusting bolt 1 before reaching target torsion, to respond to so breach and just can not detected by the first photoelectric sensor 7, product is exactly unacceptable product, the tool alert that gives the alarm.
For the structure that makes tool itself is compacter, also comprise that one is provided with the base 14 of start button and stop button, motor 10 is arranged at base 14 belows.
Further, for accuracy and the reliability that guarantees test result, tool also comprises the centering governor motion of being regulated for the centering to torsionmeter 3.Specifically, the centering governor motion comprises: for fixed head 15 that torsionmeter 3 is installed, for the horizontal adjustment plate 16 of adjusting fixed head 15 positions with vertically adjust plate 17.At horizontal adjustment plate 16 and vertical the adjustment on plate 17, adjusting screw(rod) is set, horizontal level and the vertical position of fixed head 15 are adjusted, thereby torsionmeter 3 centerings are arranged.
In sum, torsional test tool of the present utility model can be tested regulating bolt assembly quickly and easily, and then whether the adjusting bolt 1 that judges the adjusting bolt assembly is qualified with the interference fit of screw mandrel 2, high efficiency and testing result are accurate, have good marketing prospect.
Above demonstration and described ultimate principle of the present utility model, principal character and advantage.The technician of the industry should understand, and embodiment does not limit the utility model in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection domain of the present utility model.
