Technical field
The present invention relates to the detection range of hydrophobic glass, particularly the device for testing endurance of hydrophobic glass.
Background technology
Existing vehicle glass is to be processed by float glass or general sheet glass, because float glass is bigger than water with the surface tension of general sheet glass, so they all do not have the hydrophobic effect; Development along with technology; Hydrophobic glass will replace simple glass gradually, constantly popularization and application in vehicle glass, and hydrophobic glass need carry out durability test to it in R&D process; Just test the number of times that the windscreen wiper bar rubs on hydrophobic glass, judge the serviceable life of hydrophobic glass according to this.Must make the windscreen wiper bar hydrophobic glass that repeatedly rubs if want to carry out this test, workload is very big, but also is not exclusively used in the device of test hydrophobic glass permanance at present, and there is very large difficulty in test.
Summary of the invention
The device for testing endurance that the purpose of this invention is to provide hydrophobic glass a kind of simple in structure, easy to operate.
For realizing above-mentioned purpose; The present invention has adopted following technical scheme: a kind of device for testing endurance of hydrophobic glass comprises and carries model and wiper body that the print of hydrophobic glass is placed on and carries on the model; The side of print is provided with fixed cell; Windscreen wiper bar on the wiper body is pressed on the surface of print, and fixedly the windscreen wiper arm of windscreen wiper bar connects travel mechanism, and described travel mechanism drives the windscreen wiper bar and on print, moves back and forth.
Owing to adopt above technical scheme; What travel mechanism's drive windscreen wiper bar did not stop on print moves back and forth, and imitation windscreen wiper bar wiping glass for vehicle window tests out the number of times that the windscreen wiper bar rubs on hydrophobic glass; Thereby draw the serviceable life of hydrophobic glass; Realize the durability test of hydrophobic glass, this apparatus structure is simple, and is easy to operate.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Device for testing endurance like Fig. 1, a kind of hydrophobic glass; Comprise and carry model 10 and wiper body 30; The print 20 of hydrophobic glass is placed on and carries on the model 10, and the side of print 20 is provided with fixed cell, and the windscreen wiper bar 31 on the wiper body 30 is pressed on the surface of print 20; Fixedly the windscreen wiper arm 32 of windscreen wiper bar 31 connects travel mechanism 40, and described travel mechanism 40 drives windscreen wiper bar 31 and on print 20, moves back and forth.Wiper body 30 adopts the windscreen wiper arm 32 and windscreen wiper bar 31 structures that uses on the vehicle bodies, can make friction force between windscreen wiper bar 31 and the print 20 more approach windscreen wiper bar 31 and the friction force between the hydrophobic glass on the car load, the degree of accuracy of assurance measurement result.Print 20 firm being fixed in unit that be fixed carried on the model 10, can be along with windscreen wiper bar 31 does not move around, and travel mechanism 40 drives moving back and forth that windscreen wiper bars 31 do not stop on print 20; Imitation windscreen wiper bar 31 wiping glasss for vehicle window; After the friction through limited number of time travel mechanism 40 is stopped to observe the degree of wear of hydrophobic glass, thereby draw the serviceable life of hydrophobic glass, realize the durability test of hydrophobic glass; This apparatus structure is simple, and is easy to operate.
As shown in Figure 1; Described travel mechanism 40 comprises two-way Rodless cylinder 41 and two five-way electromagnetic valves 42; First venthole 421 of described two five-way electromagnetic valves 42 links to each other with first chamber 411 of two-way Rodless cylinder 41; Second venthole 422 of two five-way electromagnetic valves 42 links to each other with second chamber 412 of two-way Rodless cylinder 41; First coil 426 that the air admission hole 423 of two five-way electromagnetic valves 42 connects 70, two five-way electromagnetic valves 42 of air pump is connected controller 60 respectively with second coil 427, and controller 60 connects power supply 80.Rodless cylinder is meant and utilizes the direct or indirect mode of piston to connect extraneous topworks, and makes it follow piston realization reciprocating cylinder.The piston of the two-way Rodless cylinder 41 among the present invention is divided into first chamber 411 and second chamber 412 with cylinder body; Give vent to anger in second chamber 412 when 411 air inlets of first chamber; Give vent to anger in first chamber 411 when 412 air inlets of second chamber on the contrary; Thereby piston moves around in cylinder body, and then the outside slide block 413 that drives two-way Rodless cylinder 41 comes and goes along straight line and moves.
When the right valve of two five-way electromagnetic valves 42 is worked; First venthole 421 is communicated with air admission hole 423; Second venthole 422 is communicated with second vent port 425; Gas gets into two five-way electromagnetic valves 42 by air admission hole 423 after first venthole, 421 backs get in first chamber 411 and promote piston moves to second chamber 412; This moment, second chamber, 412 interior gases got into two five-way electromagnetic valves 42 after second vent port 425 is discharged in the air through second venthole 422, realized that the forward of two-way Rodless cylinder 41 moves; When the left valve of two five-way electromagnetic valves 42 is worked; Second venthole 422 is communicated with air admission hole 423; First venthole 421 is communicated with first vent port 424; Gas moves to first chamber 411 through getting in second chamber 412 behind second venthole 422 and promoting piston after getting into two five-way electromagnetic valves 42 by air admission hole 423; This moment, first chamber, 411 interior gases got into two five-way electromagnetic valves 42 after first vent port 424 is discharged in the air through first venthole 421, realized oppositely moving of two-way Rodless cylinder 41.
The side of described year model 10 is provided with liquid taking device 50, and this liquid taking device 50 comprises reservoir 51 and flexible pipe 52, and an end of flexible pipe 52 places the top of print 10, and the other end connects reservoir 51, and flexible pipe 52 is provided with peristaltic pump 53.Store in the reservoir 51 for concentration be 50% cleaning glass liquid; Cleaning glass liquid is dropped in print 20 under peristaltic pump 53 effects; The state of windscreen wiper bar 31 cleaning Vehicle glass panes on the imitation car load; Print 20 is cleaned in realization automatically, and the environment the when working environment of the windscreen wiper bar 31 when making test and use is fitted more, thereby further improves the degree of accuracy of test findings.
Be installed with balancing weight 33 on the described windscreen wiper bar 31; Described year model 10 horizontal arrangement, described fixed cell are to be arranged on two blocks 11 that carry on the model 10, these two blocks 11 along the moving direction of windscreen wiper bar 31 arrange and two blocks 11 between distance adjustable, print 20 is placed between two blocks 11.Balancing weight 33 guarantees when the friction force between windscreen wiper bar 31 and the print 20 is used with reality more approaching, improves the experimental result degree of accuracy.Print 20 only receives windscreen wiper bar 31 friction force effect on surface level in process of the test, so only need just can realize the fixing of print 20 to print 20 at this direction upper limit.Be block 11 to be set respectively at the two ends of print 20 prevent it among the present invention, guarantee to realize normally carrying out that this structure is comparatively simple, is easy to realize along with windscreen wiper bar 31 moves.
The exit in described first chamber 411 and second chamber 412 is equipped with air pressure regulator 46, can realize the translational speed of outside slide block 413 through regulating air pressure regulator 46 limits, thereby realize measuring the permanance of windscreen wiper bar 31 print 20 when the different motion state.
