Description of drawings
Fig. 1 is front view of the present invention.
Fig. 2 is the left view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in further detail.
As shown in Figure 1, 2, the present invention includes frame 100,4 guide rollers 8 are installed on the frame 100, the bottom of frame 100 is provided with supporting steel plate 15, and the slide block 7 that slides up and down is slidingly mounted between the guide roller 8.The middle part of slide block 7 is connected with cursor slide 3, cursor slide 3 front ends are provided with bearing pin 2, and bearing pin 2 offsets with the cam 1 that rotatably is installed on the frame 100, and the height point A of cam 1 and the distance between the low spot B usually should be greater than 40 millimeters, in the present embodiment, height point A and the distance between the low spot B of cam 1 are 55 millimeters.Cam 1 connects buncher 9 by camshaft 11, and the output shaft of buncher 9 is provided with photoelectric counter 10.The upper end of slide block 7 is provided with falling stop piece 6, and the frame 100 of falling stop piece 6 belows is provided with buffer head 5, is provided with buffer spring 4 in the buffer head 5, and the lower end of slide block 7 is provided with suspension ring 12, and during test, the handle of tested electric iron 14 is hung on suspension ring 12 by flexible bandage 13.
Before starting characteristics test, cam 1 should be in the position (position among Fig. 1) of high some A, the handle of tested electric iron 14 is hung on the suspension ring 12 of slide block 7 bottoms by flexible bandage 13, makes iron plate become horizontality when hanging and guarantees that in the distance of rigid support steel plate 15 be 40 millimeters.At the trial, buncher 9 drives camshaft 11 by shaft coupling makes cam 1 along arrow C direction (being counter clockwise direction among Fig. 1) rotation, so that the bearing pin 2 on the cursor slide 3 is fallen the low spot B of cam from the height point A of cam 1, (A, the distance that B is 2 is 55 millimeters), because cursor slide 3 is fixed on the slide block 7, therefore slide block 7 is under Action of Gravity Field, along four guide roller 8 vertical drops, the also thereupon vertical drop of tested electric iron 14 is bumped against with supporting steel plate 15, finishes single test, the continuous rotation of buncher 9 is carried out test continuously.Falling stop piece 6 is housed on the slide block 7 slide block 7 has been fallen bump against with buffer head 5 after 45 millimeters, stoped slide block 7 to continue to fall, the buffer springs 4 in the buffer head 5 can reduce impact noise.Photoelectric counter 10 on buncher 9 output shafts passes the signal along to control system, and speed and number of times are fallen in control, and test is carried out automatically until finish.
