Description
Technical field
The present invention relates to a kind of cable automatic plug-pull devices for quality center of mass measurement, belong to field of measuring technique.
Background technique
For the quality center of mass measurement of the large sized objects such as rocket, automobile, submarine, existing measuring technique is mainly static(al)
Square balance method is weighed that is, using the weight of three or four weighing sensor measurement test products by three (or four)
The reading and its relative positional relationship of sensor calculate the quality center of mass position of product to be measured.
The general step of quality center of mass measurement process is: 1, being not loaded with test product, measure the quality center of mass of tooling；2, add
Carry test product, measurement product and the total quality center of mass of tooling；3, product posture is converted, product quality matter under the posture is measured
The heart.When loading test product and switching product measurement posture, need tooling rise disengaging it from weighing sensor, Yi Mianchong
It hits, vibrate etc. and sensor is damaged, falling on tooling on weighing sensor together together with product after the completion.
In order to realize the automation of whole process, top division of labor dress inevitably has motor, obliquity sensor, limit switch etc.
Electronic device.And during above-mentioned lifting process, transformation product posture, the minor change for the cable being connected with electronic device,
Such as length variation, change in location, operator accidentally touch the accuracy that can influence quality center of mass measurement result.
As shown in fig. 6, to measure the general type of the device of product quality mass center, the device using statical moment balance method
It mainly include two parts, lower part is divided into bottom measurement part, including weighing sensor, spiral lift etc.；Top is divided into tooling,

The rolling of test product is such as realized in the adjustment of product posture, and upper layer Fixture Design has motor, in addition, in order to realize upper layer tooling
Level can also include the electronic devices such as obliquity sensor.
The step of existing quality center of mass measures is:
Step 1: upper layer tooling integrally drops to 3 (or 4) in the measurement part of bottom when being not loaded with test product
On weighing sensor, the electric operation apparatus connecting with measuring device acquires and calculates the quality center of mass of upper layer tooling；
Step 2: rising upper layer tooling, weighing sensor is disengaged it from, loads test product；Upper layer tooling and product are whole
Body falls onto the weighing sensor in bottom measurement portion point, measures total quality center of mass of test product and tooling；
Step 3: rising upper layer tooling and test product, motor work, driving test product rotation converts product posture；
Upper layer tooling and product integrally fall onto the weighing sensor in bottom measurement portion point, measure test product and work under the posture
Total quality center of mass of dress；
Step 4: rising upper layer tooling and test product, entire measurement process is completed.
Existing quality center of mass measurement method has following limitation:
In the measurement process, product and tooling gross mass centroid position subtract tooling quality center of mass position, in order to survey
The quality center of mass position of the product of amount.And during whole operation, because of frequent rise and fall tooling, if in step 1 in tooling
The cable of motor with Step 2: in step 3 motor cable change in location, as operator accidentally touches, or pullled by personnel,
Article, which is pressed onto, makes upper layer tooling stress etc., all will affect the accuracy of quality center of mass measurement result.
To sum up, the minor change of the connected cable of electronic device influences quality in existing quality center of mass measurement measurement process
The accuracy of centroid measurement result.
