Description
Technical field
The present invention relates to a kind of test machine of rotating shaft, particularly relate to a kind of rotating shaft friction force of frame sensor type and the test machine in life-span.
Background technology
Electronic installation with screen, for example laptop computer, cover-folding type mobile phone machine, usually utilize several rotating shafts as the entire pivot of opening between screen and main frame, rotating shaft must have suitable friction force, allow the user easily screen is fixed on certain angle, but friction force again can not be excessive, to avoid causing out entire difficulty.In addition, the life-span of rotating shaft also must can have been born long-term use, makes friction force all can remain on the scope of setting, thus the fabricator must test to confirm the rotating shaft quality whether qualified.Provide a kind of measuring machine that can test rotating shaft maximum static friction force and permanance though China's utility model discloses No. 2499900 patent, it has following shortcoming:
1. sensor places bolster below, the end, and main frame is placed in bolster top, the end again, and sensor has just born the weight of end bolster and main frame before measurement, so must make zero before each measurement and revise adjustment, expends time in.
2. sensor is oppressed by the long-term gravity of end bolster and computing machine, and the precision of sensor may misalignment cause fault or need often maintenance.
The invention provides a kind of frame sensor type spindle testing machine, can improve the shortcoming of prior art, make test job not need often to make zero and adjust operation, and prolonged the serviceable life of sensor.

Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in detail.
Please refer to Fig. 1.Test machine of the present invention is provided with several pivot seats 11 at a board 10 upper surfaces.Board 10 is provided with propulsion system 20 in addition, and propulsion system 20 can be servo motor, motor gear module etc., and propulsion system 20 provide suitable, the back and forth power of a rotation output counterclockwise by a transmission shaft 21.Propulsion system 20 can be arranged at board 10 inside as Fig. 1, also can install at board 10 upper surfaces, output power by transmission shaft 21.
Two straight-bars of underframe 30 are articulated in pivot seat 11, and propulsion system 20 conduct to underframe 30 by transmission shaft 21 with power.The cross bar 32 of upper frame 31 is provided with several fixed blocks 33, and fixed block 33 can grip the screen 62 of electronic installation 60, and therefore, propulsion system 20 drive underframe 30, upper frame 31 and screen 62 by transmission shaft 21 and make reciprocally swinging.
Before testing, the main frame 61 of electronic installation to be measured 60 is placed brace table 40, and screen 62 is fixed on upper frame 31 with fixed block 33, this moment is not because the two ends of sensor 50 apply power, therefore under the situation that does not have load, can prolong the life-span of sensor 50, and not need sensor 50 adjustment of making zero.
When testing, propulsion system 20 see through 21 pairs of underframe 30 application of forces of transmission shaft, and underframe 30 is by 50 pairs of upper frame 31 application of forces of sensor, so the resistance that sensor 50 two ends can the sensing rotating shaft; Before the maximum static friction force that overcomes rotating shaft 63, the stressed of sensor 50 increases gradually, and by signal wire (not illustrating) electronic signal transmission gone out; When the application of force of 31 pairs of screens 62 of upper frame during greater than the maximum static friction force of rotating shaft 63, upper and lower framework 30,31 beginnings are on main frame 61 directions are entire, what sensor 50 measured at this moment is the kinetic force of friction of rotating shaft 63, and continues to spread out of through the electronic signal of signal wire with this friction force; Screen 62 relative main frames 61 are back and forth opened entire, and the dynamic and static friction force electronic signal that sensor 50 continues to sense spreads out of, and can test the frictional force data and the serviceable life of rotating shaft 63.
Certainly, more than only be concrete exemplary applications of the present invention, protection scope of the present invention is not constituted any limitation.In addition to the implementation, the present invention can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the present invention's scope required for protection.
