Background technology
In recent years, along with Development of Multimedia Technology, the range of application of camera lens module is also more and more wider, and for example, it is widely used in digital camera, video camera and has in the portable type electronic products such as mobile phone of camera function.
The camera lens module generally comprises camera lens and microscope base.Described camera lens comprises lens barrel and is arranged at the interior a plurality of optical elements of lens barrel, for example eyeglass, distance piece, optical filter etc.Described lens barrel outer wall is provided with external thread, so that screw togather with microscope base.Described microscope base has and the corresponding resettlement section of lens barrel, and the resettlement section has and the corresponding internal thread of the external thread of lens barrel.During assembling camera lens module, can be earlier a plurality of optical elements be packed into according to a definite sequence and form camera lens in the lens barrel; Again lens group is gone into microscope base, be about to the resettlement section that lens barrel screws in microscope base, to be assembled into the camera lens module.
After the assembling of camera lens module is finished, need to adopt the method for pick test that the camera lens module of producing in batches is carried out torsional test usually, whether the camera lens module that assembles with test meets the assembling requirement.During test, operating personnel outward winding camera lens and microscope base earlier, and make microscope base be fixedly arranged on plummer; Secondly, the lower end of torsionmeter is fixed on the camera lens; Once more, make torsionmeter drive rotation of lens, until camera lens is screwed in microscope base; At last, observe the registration of torsionmeter, can obtain the acrotorque value that camera lens cooperates with microscope base.
Yet along with the development of present camera lens module toward miniaturization, the volume of camera lens is more and more littler.Therefore, when carrying out torsional test, be difficult to when camera lens is screwed in microscope base guarantee the stable of torsionmeter, cause torsionmeter in test process, to be moved easily, thereby cause test result inaccurate.
Summary of the invention
In view of this, be necessary to provide a kind of fixing torsionmeter of stablizing to promote the torque test device of accuracy rating of tests.
A kind of torque test device, it comprises a torsionmeter, a holder and a bracing frame that is fixedly arranged on this holder that is used to place determinand.This bracing frame comprises a back up pad parallel with this holder, and this back up pad offers a through hole.This torsionmeter is arranged in this through hole and is fixed on this back up pad to test the torsion of this determinand.
Compared with prior art, above-mentioned torque test device positions torsionmeter by bracing frame, can stablize this torsionmeter of fixing so that the determinand on the holder is tested in test process, thereby promotes accuracy rating of tests.

Fig. 2 is the decomposing schematic representation of the torque test device among Fig. 1.
Embodiment
For torque test device of the present invention is described further, lifts following embodiment and conjunction with figs. and be elaborated.
See also Fig. 1, be a kind of torque test device 10 provided by the invention, it is used for providing torsional test to determinand, and in the present embodiment, this determinand is that example describes with the camera lens module.This torque test device 10 comprises a holder 11, a bracing frame 12 and a torsionmeter 13.
See also Fig. 2, this bracing frame 12 comprises back up pad 121 and four fixed legs 122 parallel with this holder 11, and these four fixed legs 122 are fixed on this holder 11.This back up pad 121 offers a through hole 121a, and this torsionmeter 13 is arranged in this through hole 121a.
This torsionmeter 13 comprises one first cylinder 131, one second cylinder 132, rotating part 133, handle 134, a display part 135 and a flexible member 136.
This second cylinder 132 is connected with this first cylinder 131, and the diameter of this first cylinder 131 is less than the aperture of this through hole 121a, and the diameter of this second cylinder 132 is greater than the aperture of this through hole 121a.This first cylinder 131 is arranged in this through hole 121a.
This rotating part 133 is arranged on the free end 131a of this first cylinder 131.Wherein, the structure of this rotating part 133 is determined by determinand, as long as can clamp determinand and can drive its rotation.In the present embodiment, determinand is the camera lens module, and then this rotating part 133 is a plurality of raised structures, to clamp this determinand.
11 pairs of this holders should offer a groove 111 by rotating part 133, and this groove 111 is used to accommodate and fixing determinand, and in the present embodiment, this groove 111 is for square and just accommodate determinand.
This handle 134 is affixed with this second cylinder 132.This handle 132 is arranged on the free end 132a of this second cylinder 132.In the present embodiment, this handle 134 is tried one's best near the end of these second cylinders 132 with the axial vertical of this second cylinder 132 and this handle 134, so, can make operating personnel laborsaving when rotating this handle 134.Preferably, this handle 134 and this second cylinder 132 structure that is one of the forming so, can make structure more firm.
This display part 135 is a pointer watch dial, is used to show torque value, and this display part 135 is arranged on the end face of free end 132a of this second cylinder 132.Be appreciated that this display part 135 also can show for numeral, and also can separate setting with this second cylinder 132.
