Embodiment
With example the utility model is described in further detail with reference to the accompanying drawings below:
Noise test auxiliary locator comprises three parts: test frame, right angle testing jig and height measuring device, wherein test frame is the core of this device.Referring to Fig. 2, Fig. 3 a, b, c, test frame 10 combines with right angle testing jig 20, the measuring position that is used to measure the length and width of toy and determines microphone, and height measuring device shown in Figure 5 is used for measuring the height of toy.Test frame 10 comprises a L shaped frame body, this L shaped frame body mutually vertically is provided with and constitutes perpendicular to the location- plate 11 and 12 of testing stand by two, L shaped frame body can be to be formed by one flat plate folding quarter bend, also can be to be fixedly connected to form by two orthogonal location-plates.The coboundary of each location-plate is provided with the scale portion of measuring, described measurement scale portion can be the scale that directly is engraved in the location-plate top, also can be to be installed on orthogonal two straight steel rulers 111 of location-plate coboundary and 121 respectively, wherein one is straight steel ruler 121 length scales, and another straight steel ruler is a width scale 111.A wherein location-plate 12 outer setting of L shaped frame body have carriage, and carriage comprises the slide rail 13 that is packed in location-plate 12 outside surfaces and traverses location-plate, and be slidingly connected with described slide rail, slide block 14 that can level slides on slide rail 13; And in that (when carrying out the test of European EN71 desktop, ground sounding toy noise, this preset distance is 50mm) is provided with an altitude scale 16 vertical with testing stand apart from these location-plate 12 preset distance places, the starting point of altitude scale 16 is a testing stand.Described altitude scale is fixedlyed connected with an end of a connecting rod 17, and an end of the other end of connecting rod and a scale pointer 15 all is fixed on the slide block 14 by coupling arrangement, and slide block 14 just can drive tuning drive gear 15 and drive altitude scale 16 by connecting rod 17 and move horizontally along this location-plate 12 like this.In actual applications, strong for making altitude scale, this altitude scale is packed on the fixed head 161 by screw 162, becomes one with fixed head.
Noise test auxiliary locator also comprises a right angle testing jig as shown in Figure 4, and described right angle testing jig is made of three flat boards, and described three flat boards are vertical mutually in twos to be connected, and forms cubical three faces.Noise test auxiliary locator also comprises height measuring device as shown in Figure 5, and height measuring device is the height that is used for measuring toy.Height measuring device comprises a base 31, is fixed on the base and also is testing stand perpendicular to the starting point of second altitude scale, 32, the second altitude scales 32 of testing stand; And be fixed on the fixed bar 33 that is parallel to second altitude scale 32 on the described base 31, second carriage is set on the fixed bar 33, second carriage comprises a slide block 34, slide block 34 and fixed bar 33 loose fits, and slide block 34 can move up and down along fixed bar 33.34 are equipped with a horizontal draw point 35 on the slide block, and horizontal draw point 35 passes through second altitude scale 32, and slide block 34 can slide up and down by the horizontal draw point 35 of drive, are used for measuring and indication toy height on second altitude scale.Horizontal draw point is fixed on the slide block by hold-down nut 36, and therefore the fixed position of horizontal draw point can be adjusted, and promptly draw point 35 can move horizontally in slide block 34.
The method that adopts above-mentioned noise test auxiliary locator to carry out the test of toy noise is as follows, as Fig. 1, shown in Figure 2, before carrying out the test of toy noise, need to measure earlier reference case 5 sizes of toy, its method is that toy is placed on the test board by normal operating condition, the location-plate 11 among the figure is close in two sides of toy, 12, with the two sides of two right angle testing jigs respectively with test board and location- plate 11,12 are close to, the another side of right angle testing jig is close to the two sides of toy respectively, and the joint by right angle testing jig 20A and length scales 121 and the joint of right angle testing jig 20B and width scale 111 can be read length (A) and wide (B) of toy.The height of toy (C) is measured by height measuring device, determines the toy peak by moving up and down horizontal draw point 35, and read the toy height on second altitude scale 32, and like this, reference case 5 sizes of toy have just accurately also obtained easily.Next just microphone position can have been determined.Make tuning drive gear 15 on length scales 121, point to A/2 by moving slider 14, close altitude scale 16 surfaces of microphone end face, because therefore tuning drive gear tip and altitude scale flush left make the microphone centrally aligned scale left side; Because the distance on altitude scale surface lies location-plate surface is 50mm, guaranteed that therefore microphone end face and toy surface is at a distance of 50mm; Adjust the microphone height then, make the position of H/2=(C+50mm)/2 on its centrally aligned altitude scale 16, like this, the measurement point of toy sample length direction has just been determined.Sample Rotate 180 °, can record another point of length direction equally; Two measurement points of Width also in kind can be determined.This shows, adopt noise test auxiliary locator of the present utility model, can accurately make things convenient for the position of determining the test microphone intuitively, improved toy noise precision of test result and efficient.
Be understandable that, for those of ordinary skills, can be equal to replacement or change according to technical scheme of the present invention and inventive concept thereof, and all these changes or replacement all should belong to the protection domain of the appended claim of the present invention.
