Abstract

The invention relates to a torque force detecting method of a lens fixing seat for a camera of a mobile phone. The torque force value of a thread of the fixing seat can be measured precisely, and the torque force of the thread is mastered accurately. The method is simple, and is easy to operate; further, the test result is precise; and the method is applicable to the popularization and the use in the test of internal threads in the precision electronic field.

Description

A kind of torque detection method of mobile phone cam lens fixing base

Technical field

The present invention relates to the precise electronic product field, especially a kind of torque detection method of mobile phone cam lens fixing base.

Background technology

At present, the detection mode of thread torsion is only for measuring relevant size, yet judge the big probable value of torsion with the size accuracy of size, thread torsion can't accurately be controlled, cause when judging whether product that the client provides meets the specific torsion production standard of product, judge inaccurate, thereby cause the production assembling process instability of product, influence product percent of pass.

Summary of the invention

Fundamental purpose of the present invention is to provide a kind of torque detection method of mobile phone cam lens fixing base, can accurately record the torque value of holder thread, controls thread torsion exactly.

To achieve these goals, solution of the present invention is:

Step 1, tooth rule and the coaxial close fit of torsionmeter;

Step 2, holder product slowly screw in tooth rule 1～2 circle, with fixing a little to holder;

Step 3, the torsionmeter pointer is made zero;

Step 4, the holder product is screwed in tooth rule gently equably, range estimation screws in the position up to holder and reaches pre-provisioning request substantially;

Step 5, the whole assembly of step 4 is positioned on the test platform of altitude gauge,, measures and adjust the holder height again to designated value with the zero clearing on tooth rule surface of altitude gauge probe;

Step 6, read and write down the reading on the torsionmeter.

Before carry out step 2, can carry out outward appearance to the holder product earlier and confirm, and will blow clean in the holder product tooth with air gun.

Adopt such scheme can accurately record the thread torsion of mobile phone cam lens fixing base, can grasp the real-time torsion situation of holder effectively, make with it operations such as the Related product production that cooperates, detection, assembling quicker, convenient, accurately, the stability and the product percent of pass of raising production.This method is simple to operation, and test result is accurate, is suitable for promoting the use of of precise electronic field internal thread test.

Description of drawings

The invention will be further described below in conjunction with accompanying drawing:

Figure 1 shows that the assembling synoptic diagram of tooth rule and torsionmeter;

Figure 2 shows that product structure figure;

Figure 3 shows that product screws in the synoptic diagram of tooth rule;

Fig. 4 is the partial enlarged drawing of Fig. 3.

Embodiment

A kind of torsion of mobile phone cam lens fixing base detects tool air gun, hairbrush, torsionmeter 1, tooth rule 2 and altitude gauge etc.Its detection method is as follows:

At first, must make outward appearance before product detects and confirm, and thread be blown clean with air gun; Secondly whether, confirm torsionmeter 1 whether in proofreading and correct the term of validity, it is intact and clean with hairbrush to confirm that tooth is advised 2 threads.

After preliminary work is finished, earlier with tooth rule 2 and torsionmeter 1 coaxial assembling, and not shown with fixed pin 11(, invisible) tooth rule 2 are fixing, as shown in Figure 1;

Then, left hand is torsionmeter 1 rotating disc fixedly, the right hand slowly screws in tooth rule 1～2 circle with holder product 3, extremely shown in Figure 4 as Fig. 2, product must confirm whether product 3 directions are correct before screwing in tooth rule 2, in order to increase the friction force between finger and the holder product 3, guarantee the stability of operating, hand thumb and forefinger must be put on fingertip;

After product 3 screwed in, left hand unclamped torsionmeter 1 rotating disc, and torsionmeter 1 pointer is made zero;

Again then, left hand is held torsionmeter 1 chassis, the mild uniform product 3 that screws in of the right hand, whether the position that palpus visualization product 3 screws in the screw-in process reaches the operation or work standard requirement of this type product 3, moves and measures highly with altitude gauge if reached just to stop to screw in;

Advise zero clearing on 2 surfaces with the altitude gauge probe at tooth, measurement products height again, confirm whether to have the operation or work standard that reaches this type product 3 to require the position, product 3 just can read position shown in the red point on the torsionmeter 1 after rotating to specified altitude assignment, there is not scale between the 0-20g on the torsionmeter 1, so when torsion is between this, 20 scales on torsionmeter 1 rotating disc must be rotated counterclockwise to chassis scale 0 aligned in position after reading again;

After value is intact product 3 is screwed out counterclockwise, registration torsion force measured value, and the torsion standard value contrast of the holder product 3 of style number therewith, with the torque value of definite this product whether in acceptability limit.

To survey the back product and install and enclosed the label reservation with sack, and the rule of the tooth on the torsionmeter taken out put back to tooth rule holder.

The above only is preferred embodiment of the present invention; it is not qualification to protection domain of the present invention; the those skilled in the art is in the spirit and scope of the present invention that do not break away from claims and limited; the many variations that the present invention is made all falls into protection scope of the present invention in the form and details.

Claims

1. the torque detection method of a mobile phone cam lens fixing base is characterized in that, this detection method may further comprise the steps:

Step 1, tooth rule and the coaxial close fit of torsionmeter;

Step 2, holder product slowly screw in tooth rule 1～2 circle;

Step 3, the torsionmeter pointer is made zero;

Step 6, read and write down the reading on the torsionmeter.

2. the torque detection method of a kind of mobile phone cam lens fixing base as claimed in claim 1 is characterized in that, earlier the holder product was carried out outward appearance and confirm before carry out step 2, and will blow clean in the holder product tooth with air gun.
