Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is done concrete introduction.
The adjusting bolt assembly is for a vitals on the automobile light-modulating motor, its structure 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, and is interference fit between adjusting bolt 1 and the screw mandrel 2.So-called torsional test just refers to exchange joint bolt 1 and screw mandrel 2 and applies a certain size relative torsion, and we are called target torsion with this torsion among the present invention.If under this target torsion, relative rotation does not occur with screw mandrel 2 in adjusting bolt 1, and then this assembly is certified products; Otherwise counterrotating words occur with screw mandrel 2 in adjusting bolt 1, and then 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 invention comprises: torsionmeter 3, be used for fixing screw mandrel 2 torsion aluminum barrel 4, be used for the fixed block 5 of secured adjusted bolt 1, with fixing the first inductive disks 6 of torsion aluminum barrel 4, be used for the first photoelectric sensor 7 that control detects the first inductive disks 6 position of rotation, with fixing the second inductive disks 8 of fixed block 5, be used for the second photoelectric sensor 9 that control detects the second inductive disks 8 positions, motor 10 and the gear train 11 that drives fixed block 5 rotations.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.
We can find out from Fig. 1, screw mandrel 2 has the lug boss vertical with length direction 201, torsion aluminum barrel 4 is ingenious this structure of having utilized just, at torsion aluminum barrel 4 a groove structure with lug boss 201 respective outer side edges is set, when torsion aluminum barrel 4 drops to certain position, thereby just in time cooperating with lug boss 201, the groove structure clamps screw mandrel 2.
Further, this tool also comprises for the elevating mechanism of adjusting torsionmeter 3 and torsion aluminum barrel 4 height.Preferably, elevating mechanism comprises: slide rail 12 and be used for to realize the cylinder 13 of lifting.
In order to understand better the present invention, the use procedure of tool is summarized as follows: adjusting bolt 1 is fixed on the fixed block 5, then the height of torsion aluminum barrel 4 is dropped to and just in time clamp screw mandrel 2; Starter motor 10, fixed block 5 rotates under the driving of gear train 11, in fact gear train 11 is by a plurality of gear mix proportions, because adjusting bolt 1 is fixed together with fixed block 5, so adjusting bolt 1 also just must be rotated, the screw mandrel 2 of drive and its interference fit rotates, and torsion aluminum barrel 4 will apply torsion to screw mandrel 2 in this process, and the size of torsion can read from torsionmeter 3.
In actual testing process, torque magnitude often has a desired value, is 3.5Ncm such as standard commonly used on the market, and this tool can be neatly according to market demand target setting torsion, and 3.5Ncm herein only is 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 reached target torsion, its induction breach was just in time detected by the first photoelectric sensor 7, and representative products is certified products.Then motor 10 counter-rotatings, torsion is progressively cancelled, and the adjusting bolt assembly is returned to original state, cooperatively interacts to control rotary position by the second inductive disks 8 and the second photoelectric sensor 9, and control principle is not given unnecessary details with the first inductive disks 6 herein.
If relative rotation has occured 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, comprise that also 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 for the centering governor motion that the centering of torsionmeter 3 is regulated.Specifically, the centering governor motion comprises: be used for to install torsionmeter 3 fixed head 15, be used for adjusting the horizontal adjustment plate 16 of fixed head 15 positions and vertically adjusting plate 17.At horizontal adjustment plate 16 and the vertical plate 17 of adjusting adjusting screw(rod) is set, horizontal level and the vertical position of fixed head 15 is adjusted, thereby torsionmeter 3 centerings are arranged.
In sum, torsional test tool of the present invention can be tested regulating bolt assembly quickly and easily, and then whether the adjusting bolt 1 of judging the adjusting bolt assembly is qualified with the interference fit of screw mandrel 2, and high efficiency and testing result are accurate, have good marketing prospect.
More than show and described ultimate principle of the present invention, principal character and advantage.The technician of the industry should understand, and embodiment does not limit the present invention in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection scope of the present invention.
