During dynamic device 64, the side of the circular groove and screw rod to be measured of two pieces of metallic plates of clamping plate 61 offsets, and realizes and clamps；When to be measured
When screw rod is disconnected with clamping section 3 and Impulsive load portion 4, handling driving device 64 is again started up, clamping plate 61 is to be measured in clamping
While screw rod, drive screw rod to be measured to move upwards, screw rod to be measured is jacked up out of leading-out portion 2 upper plate 21, convenient unloading
The screw rod of detection is completed.Certainly, the structure not limited to this of handling part 6.
In addition, the application further includes display unit 7 and control unit.Wherein, display unit 7 is connected with test section 5, is mainly used for receiving
Collect the various load that simultaneously real-time display screw rod to be measured is born, facilitate operating personnel to judge whether to continue to load, in the specific reality
Apply in example, display unit 7 is specially the digital display type push-pull effort table of the upper surface of the roof supporting 11 installed in test bracket 1.Control
Portion is connected with test section 5, clamping section 3 and Impulsive load portion 4 respectively, according to the feedback information of the test section 5 received, control folder
Tight portion 3 and Impulsive load portion 4 act, convenient to realize automation.Control unit includes the controlling switch 8 being installed on test bracket 1.
When control unit judges that the load that clamping section 3 and Impulsive load portion 4 are applied is smaller, booster air pump, air pump fills to clamp driving
Put 32 and Impulsive load driving device 42 continue slowly to inflate, pressure gradually increases, realize loading；When control judges clamping section 3
When the load applied with Impulsive load portion 4 reaches preset value, air pump shuts down, and air pump stops to 32 He of driving clamping device
Impulsive load driving device 42 is inflated, and completes test.
In addition, being equipped with balance performance monitor 9 between the support side plate 13 of test bracket 1 and driving clamping device 32, it is used for
Operating personnel judge whether the operating of the equipment keeps balancing in detection process, and balance performance monitor 9 uses dial plate form, convenient
Operating personnel intuitively read judgement.In addition, being additionally provided with air gauge 10 near each driving cylinder, operating personnel are facilitated to detect
During judge air pressure in each cylinder, on the one hand advantageously ensure that safety, be on the other hand conducive to operating personnel and judge to work as
Whether the pressure value of preceding each cylinder output is consistent with the numerical value shown in display unit 7.
Operating process provided by the present invention for the automatic full inspection test equipment of automobile power back door screw rod is as follows：
Display unit 7 and controlling switch are opened, inputs related preset value；
Nut to be measured is fixed on the upper top 21 of guide part 2；
Start driving clamping device 32, the crank of toggle 312 rotates, and drives feed screw nut 311 to rotate, leading screw
The nut slider of nut 311 drives the mobile fixture block being attached thereto close to nut to be measured, until clamping the side of nut to be measured；
Start handling driving device 64, clamping plate 61 opens, and clamps the bottom sides of screw rod to be measured；
Start test section 5；
Driving clamping device 32 and Impulsive load driving device 42 are slowly loaded to the side of screw rod to be measured and nut respectively；
Read the reading shown on display unit 7；
Until screw rod to be measured starts bent, stop the loading of driving clamping device 32, and the maximum read on display unit 7 resists
Curved intensity level；
Until screw rod to be measured departs from nut, stop the loading of Impulsive load driving device 42, and read on display unit 7
Maximum impact strength value and the screw rod rotation elastic angle value of riveting；
Close clamping section 3, Impulsive load portion 4 and test section 5；
Handling driving device 64 is again started up, clamping plate 61 moves up, and screw rod to be measured is jacked up out of guide part 2；
Screw rod to be measured is removed, completes a working cycles.
In conclusion one kind provided by the present invention is used for the automatic full inspection test equipment of automobile power back door screw rod, including
Test bracket 1, guide part 2, clamping section 3, Impulsive load portion 4 and test section 5.Guide part 2 is longitudinally fixed by screw rod to be measured.Due to
Clamping section 3 clamps the side of screw rod to be measured, and screw rod to be measured does not move axially；Start the detection of test section 5 clamping section 3 at the same time to apply
The load value of screw rod side to be measured is added to, measures the maximum flexural strength of screw rod to be measured.Again since Impulsive load portion 4 is from guiding
The bottom in portion 2 jacks up guide part 2, and when shock loading reaches certain value, guide part 2 is relative to screw rod to be measured along test bracket 1
Move up, jack up nut, nut is departed from screw rod to be measured, measuring screw rod to be measured, most on the whole impact strength and screw rod rotation riveting are loose
Tightness.During the test, clamping section 3 and Impulsive load portion 4 apply load to screw rod to be measured at the same time, close to the reality of screw rod to be measured
Border stressing conditions, with coupling measurement, measuring method is more reasonable, it is therefore possible for the detected that screw rod to be measured each performance parameter it is more accurate.
Finally, it is to be noted that, herein, such as term " comprising ", "comprising" or its any other variant
Non-exclusive inclusion is intended to, so that process, method, article or equipment including a series of elements not only include
Those key elements, but also including other elements that are not explicitly listed, or further include for this process, method, article or
