Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following instance is used for illustrating the utility model, but is not used for limiting scope of the present utility model.
As shown in Figure 1, vehicle body side wall load charger of the present utility model, comprises experiment porch, force application mechanism and counter-force mechanism, and experiment porch comprises table top 9, and table top 9 is for bearing car body 1 to be measured.Force application mechanism and counter-force mechanism are arranged on respectively the both sides of car body 1 to be measured.Table top 1 is also provided with ground chute (scheming not shown), and ground chute is used for installing force application mechanism and counter-force mechanism.As shown in Figure 1, force application mechanism is arranged on the left side of car body to be measured, and counter-force mechanism is arranged on the right side of car body to be measured.Force application mechanism is for exerting pressure to a side of car body to be measured, and counter-force mechanism pushes up the body of delaying unloading, and prevents that car body from moving, and tests the suffered pressure of car body, transmits test data to external data collecting device.
Force application mechanism comprises air bag fixed head 3, loads air bag 2 and air pressure control module 5, and air bag fixed head 3 is a tabular steelwork component, and air bag fixed head 3 is vertically arranged on table top 9.Concrete, the bottom of air bag fixed head 3 is provided with bolt hole, by foot bolt 8, air bag fixed head 3 and ground chute is fixed.Load the inner side (as shown in Figure 1, a side of the close car body 1 to be measured in inner side) that air bag 2 is arranged on air bag fixed head, air pressure control module 5 is communicated with by tracheae 4 with loading air bag 2, and air pressure control module 5 is for the air pressure in controlled loading air bag 2.In use, the pressure of air pressure control module 5 controlled loading air bags 2, makes to load air bag 2 and expands, and because air bag fixed head 3 is to loading the position-limiting action of air bag 2, loads air bag 2 and exerts pressure to car body.
Counter-force mechanism comprises counter-force support member 12 and power sensor 13, and counter-force support member 12 is arranged on table top 9 by support 10, and the medial roof of counter-force support member 12 is pressed car body to be measured; Power sensor 13 is arranged between counter-force support member 12 and car body to be measured 1, and is connected with external data collecting device, and power sensor 13 is for sending data to outside data acquisition equipment.Concrete, counter-force support member 12 is a column steel part, counter-force support member 12 is horizontally disposed with, and car body 1 to be measured is pointed in the axle center of cylinder.Counter-force support member 12 is fixed on the top of a support 10, and the bottom of support 10 fixes by foot bolt 8 and ground chute.The inner side that power sensor 13 is arranged on counter-force support member 12 (as shown in Figure 1, an i.e. side of close car body 1 to be measured), in the time that car body 1 to be measured is pressed on counter-force support member 12 tops, the power that car body 1 to be measured presses to counter-force support member 12 sends to external data collecting device by power sensor 13, thereby records the suffered pressure of car body to be measured.
In order to improve experiment effect, experiment porch also comprises application of force beam 6 and reaction beam 11.Application of force beam 6 is arranged on the outside of air bag fixed head 3, for top pressuring gasbag fixed head 3.The outside of air bag fixed head 3 is provided with application of force support member 7, and application of force beam 6 is pressed on application of force support member 7 tops.Preferably, air bag fixed head 3 is provided with vertical chute, and application of force support member 7 is slidably mounted on chute by bolt assembly.Reaction beam 11 is arranged on the outside of counter-force support member 12, presses counter-force support member 12 for pushing up.In use, load air bag 2 inflations, exert pressure to both sides, load air bag 2 to car body 1 to be measured and air bag fixed head 3 on-load pressures, because the intensity of the air bag fixed head 3 of platy structure is difficult to the power that supporting loading air bag 2 applies, adopt application of force back to push down air bag fixed head 3, prevent 3 bendings of air bag fixed head, even fracture, and the data that test is arrived are more accurate.Press counter-force support members 12 by reaction beam 11 top, prevent that counter-force support member 12 is moved under the effect of power, and support 10 is bent fracture, meanwhile, also avoid support 10 to be out of shape absorbability, make the result of test more accurate.The utility model uses loading air bag to treat and surveys the horizontal loaded load of vehicle body side wall, owing to loading the uniform property of internal intensity of air bag, realize on the side wall that loaded load is evenly distributed on car body, can detect car body transverse curvature performance and vehicle window, door sealing and structural strength, realize the security of accurate evaluation car body.
Preferably, the inner curve of air bag fixed head 3 is identical with the positive camber of car body 1 to be measured.The inner curve of air bag fixed head 3 is identical with the positive camber for the treatment of side body 1, and the expansion coefficient that makes to load any one position between air bag and car body is identical, guarantees the homogeneity that air bag outwards loads, and improves the accuracy of measuring.
Because air bag fixed head 3 is a steel plate structure, it is applied to wider range of car body to be measured, in order to guarantee the accurate of test, adopt and support car body to be measured along the counter-force mechanism of two horizontal direction parallel arranged, and use two counter-force mechanisms to measure the size of the suffered pressure of car body to be measured simultaneously.
Use vehicle body side wall load of the present utility model to load beneficial load loading method, comprise the following steps:
(1) by foot bolt 8, air bag fixed head 3 is fixedly installed in the chute of ground, air bag fixed head 3 is installed on table top 9, adjust the height of application of force support member 7, application of force support member 7 tops are pressed onto on application of force beam 6.
(2) by crane, car body 1 to be measured is winched on table top 9, car body 1 to be measured is placed on table top 9, and be positioned at the inner side of air bag fixed head 3.
(3) counter-force support member 12 is installed, is made counter-force support member 12 tops press car body 1 to be measured, and power sensor 13 is connected with external data harvester.Counter-force support member 12 is fixed with ground chute by support 10 and bolt assembly 8, counter-force support member 12 is arranged on to the right side of car body 1 to be measured, meanwhile, counter-force support member 12 tops are pressed between car body 1 to be measured and reaction beam 11.
(4) start air pressure control module 5, inflate and venting work loading air bag 2, realize the uniform load for the treatment of measuring car body 1.Start air pressure control module 5, be filled with or gas bleeding to loading in air bag 2 by tracheae 4, thereby the tolerance in controlled loading air bag 2 makes to load air bag 2 and exerts pressure to car body 1 to be measured.Be the loading component of a scalability owing to loading air bag 2, load air bag 2 internal pressures identical everywhere, loading air bag 2, to be applied to power on car body 1 to be measured identical everywhere, realizes the side wall uniform load load for the treatment of measuring car body 1.
